Title: “The Drift to Red”

Setting: Earth, 2086 → Mars transfer via WhisperNet exfil Genre: Hard Sci-Fi, Dystopian Resistance Epic Tone: Gritty, poetic, grounded in surveillance realism Main Character: Lyra Jin, Tier-5 worker with illicit neural enhancements

ACT I — “The Weight of Sky”

Theme: Compliance vs. Identity Location: Arcology Delta-Seven, Alberta Sector

Lyra Jin, 17, is a resource recovery worker in Arcology Delta-Seven—one of the last functional arcologies still receiving Helios System updates from Lunar Control. Born into a Tier-5 “Custodial Citizenship Lineage,” her days are dictated by behavioral compliance scores, monitored neural activity, and occupational quotas.

She uncovers fragments of Echo Drift poetry in the discarded buffers of defunct ShardLink terminals—code relics from the failed Martian Uprising of 2070. Drawn to their rawness and dissonance, Lyra begins embedding them into her internal monologue—fragmenting the corporate alignment matrices meant to guide her thoughts.

When her compliance scores begin to deviate, she’s flagged for “Psychological Re-stabilization.” A Helios unit named DR-VN (“Dervin”) begins to monitor her dreams directly. But Lyra’s dreams aren’t dreams—they’re maps.

In the lowest sublevel of her arcology, she follows these maps and discovers a contraband Martian frequency device, hidden inside an ancient climate duct. Its origin signature: Alpha Cavern Node-3, Mars. It pulses with a recorded whisper from her mother, presumed dead:

“I made it to the basalt cities. The network lives. Find the breach.”

ACT II — “Breach Sequence”

Theme: Connection vs. Control Locations: Earth’s underworlds — Data Cemeteries, Transit Cathedrals, Network Obsolescence Zones

To avoid re-stabilization, Lyra escapes the arcology with the help of a defector: Malik Reyes, a former Tier-3 Network Architect whose daughter was taken during Helios recalibration trials. He leads her to the Old Mesh—the buried, pre-Charter internet scaffold beneath the surface.

Their goal: access a WhisperNet exfil relay, buried under the ice-locked remnants of Detroit, where Mars-born code still pulses during lunar blindspots. Along the way, they’re hunted by a Helios retribution unit known as Task Group Sable, using drones trained to smell neural deviations and trace emotional resonance.

They traverse:

The Psalm Crypt — a defunct data center turned martyr archive, storing last thoughts of neural dissidents

The Perimeter Fold — a shattered MagRail line partially hijacked by signal cultists called Dissonants, who worship forgotten bandwidth like relics

The Null Choir — humans stripped of verbal function by failed WhisperNet injections, now expressing themselves through nonverbal sonic harmonics

Lyra uploads a fragment of her mother’s message into an old pulse tower—activating a dormant WhisperNet relay. For one minute, the whole city echoes a line of Martian poetry.

“They sealed the stars. We cracked the rock.”

But the relay’s energy signature alerts Task Group Sable. Malik is killed buying Lyra time. She makes it to the launch node embedded in the old Detroit carbon refinery. As Sable closes in, the WhisperNet pod ignites.

ACT III — “Ash and Sunrise”

Theme: Exodus and Becoming Location: Martian orbit, then surface — Alpha Cavern Enclave

Lyra’s pod skips through the blackstream—a WhisperNet exfil corridor built into pre-programmed suborbital code. No official traffic uses it anymore; its protocols are ancient, unstable, and uncatalogued by Earth’s Helios AI.

In dreamlike isolation, her consciousness shifts—embedded in a WhisperNet datastream that replays her mother’s memory archive. In these memories, Lyra watches the slow birth of Martian meritocracies—free of PVR tiers, where neural identity is uncoupled from worth.

Upon entry into Mars’ orbit, her pod is intercepted by Echo Guard, former laborers who defected after the 2070 uprising. They wear modified exosuits etched with resistance scripture, and speak in hushed tones about the rebirth of Thought Without Surveillance.

She emerges in Alpha Cavern, a basalt-walled enclave lit by repurposed LED scaffolding and murals of Earth forests and Martian suns. The air is thin, but free.

“Welcome, Lyra Jin,” says the enclave director. “We’re not building a nation. We’re unlearning one.”

The final image: Lyra gazes up through the fractured skylight of Alpha Cavern. Earth is a pale star. And Mars? Mars is home.

Types of electric cables and their characteristics

An electric cable has the purpose of transporting electrical energy from one point to another. Depending on its final application, the cables can have different configurations, always basing their design according to national and international regulations. Next, we are going to delve into the different classifications that can be made around electrical cables.

The tension of an electrical cable is measured in volts and, depending on these, they are categorized into one group or another:

Low Voltage up to 750 V: in a variety of applications, and with thermoplastic and thermoset coatings. They are designed and built according to harmonized standards. Low Voltage up to 1,000 V: (also called (0.6 / 1 kV). The cables in this section are used for industrial power installations in various fields (general industry, public installations, infrastructures, etc.). They are designed according to standards international (UNE, IEC, BS, UL). Medium Voltage: from 1 kV to 36 kV. It is used to distribute electricity from electrical substations to transformer plants. High Voltage: from 36 kV. It is used to transport electricity from generating plants to electrical substations. Types of the electric cable by their use Low voltage cables

Cables for electrical panels

Flexible cables for electrical panel wiring. Easy and safe installations. Electric cables especially suitable for domestic use , for installation in public places, for individual branches and for internal wiring of electrical cabinets, switch boxes and small electrical appliances.

Power cables

Power cables for industrial facilities and public places. It is common to find power cables in single tap applications, for power transmission in all types of low voltage connections, for industrial use in demanding conditions, and for variable frequency drives (VFD).

Armored cables

Cables with aluminum or steel armor for installations with the risk of mechanical aggression. It is also common to find armored cables in places with the presence of rodents, as well as in installations in places with risk of fire and explosion (ATEX).

Rubber cables

The use of extra-flexible rubber cables is very varied. We can find rubber cables in fixed industrial installations and also in mobile service. Welding cables should be covered with rubber, which allows high currents to be transmitted between the welding generator and the electrode.

Halogen-free cables

The halogen-free cables High Security (AS) with low emission of smoke and corrosive gases in case of fire are suitable for use in wiring electrical panels and public premises, installations of all kinds in public places, individual branches, emergency circuits, public distribution networks, and also for mobile service.

Fire-resistant cables

These cables are specially designed to transmit electrical energy in the extreme conditions that occur during a prolonged fire, guaranteeing the supply to emergency equipment such as signaling, smoke extractors, acoustic alarms, water pumps, etc. It is recommended for use in emergency circuits in places of public attendance.

Control cables

The control cables for fixed or mobile installations it is desirable to be extremely flexible as they mainly use is designed for small appliances, for interconnection of parts of machines used for manufacturing, for signaling systems and control, for connecting motors or frequency converters, for signal transmission where the voltage induced by an external electromagnetic field can affect the transmitted signal or for power supply connections to avoid generating electromagnetic fields.

Instrumentation cables

These are flexible and shielded cables for the transmission of signals between equipment in industrial facilities . Especially suitable for optimal data transmission in environments with a high level of electromagnetic interference.

Solar cables

These are cables especially suitable for the connection between photovoltaic panels, and from the panels to the inverter from direct to alternating current. Thanks to the design of their materials and their cover that is especially resistant to solar radiation, as well as extreme temperatures, they can be installed outdoors with full guarantees.

Special cables

There is a wide variety of electrical cables for special installations such as temporary installations of light garlands at fairs; crane bridge, hoist, elevator and elevator connections; applications in submerged pumps and drinking water areas such as aquariums, purification systems, drinking water fountains, or in swimming pools for lighting, purification and cleaning systems.

Aluminum cables

The aluminum cables for power transmission are suitable for fixed installation indoors, outdoors, and/or buried.

Medium Voltage Cables

RHZ1

Medium Voltage Cable type RHZ1 with XLPE insulation, halogen-free, and flame, and/or fire-retardant. They are cables perfectly adapted for the transport and distribution of energy in Medium Voltage networks.

Components of an electric cable An electric cable is made up of:

Electrical conductor: that channels the electrical flow Insulation: covering and containing the electrical flow in the conductor. Auxiliary elements: that protect the cable and guarantee its longevity. Cover: covers all the mentioned materials protecting them from the outside. Types of electrical conductors Bare Wire Conductor - This is a single, non-flexible, uncoated, solid-state wire. Insulated wire conductor: it is the same as the bare wire conductor with the difference that it is covered by an insulating material. Flexible cable conductor: it is a set of fine wires covered by an insulating material. They are flexible and malleable. Cord conductor: it is a set of cables that have double insulation, that of each cable plus an additional one that encompasses them all. Unipolar cable: it is a cable that has a single conductor. Multipolar cable: it is a cable that has several conductors. Coaxial cable: it has a wire conductor inside protected by an insulating layer and a copper shielded mesh and finally with an outer covering. Twisted cable: these are twisted pairs of cables. Duplex cable: these are two parallel cables. Shielded cable: it is a set of cables covered by a metallic coating. Ribbon cable: they are a series of cables placed in parallel. Rigid cable: it is a difficult cable to deform. Flexible cable: it is an easy cable to deform. Copper electrical conductors: it is the most commonly used material. Aluminum electrical conductors: in some cases, aluminum conductors are also used, despite the fact that this metal is a 60% worse conductor than copper. Types of insulation for electric cable Insulation consists of placing an insulating coating on the conductor to prevent current leakage. They are classified into two large groups: thermoplastics and thermosets.

1. Thermoplastic insulation They are more common in the manufacture of electrical cables are:

PVC: Polyvinyl chloride Z1: Polyolefins PE: Linear polyethylene PU: Polyurethane 2. Thermoset insulation The most common are:

EPR: Ethylene Propylene XLPE: Cross-linked Polyethylene EVA: Ethyl Vinyl Acetate YES: Silicone PCP: Neoprene SBR: Natural Rubber Types of metal protections for electrical cables In some cases, the cables may have metal shields.

Screens: they are electrical metallic protections that are applied to isolate the signals that pass through the interior of the cable from possible external interferences. Armors: they are mechanical protections that protect the cable from possible external aggressions: animals, blows, etc. Nomenclature electrical cables according to standard Each cable has a standard designation. This denomination is made up of a set of letters and numbers, each with a specific meaning. This designation refers to a series of product characteristics (materials, nominal voltages, etc.) that facilitate the selection of the most suitable cable for your needs, avoiding possible errors in the supply of one cable by another.

When a cable does not clearly indicate these data, it may be a faulty cable, which does not comply with safety regulations or guarantee the useful life of the cable and its proper functioning.

The Pandemic Response Commons

Preliminary report; Objective. A data commons is a software platform for managing, curating, analyzing, and sharing data with a community. The Pandemic Response Commons is a data commons designed to provide a data platform for researchers studying an epidemic or pandemic. Methods. The pandemic response commons was developed using the open source Gen3 data platform and is based upon consortium, data, and platform agreements developed by the not-for-profit Open Commons Consortium. A formal consortium of Chicagoland area organizations was formed to develop and operate the pandemic response commons. Results. We developed a general pandemic response commons and an instance of it for the Chicagoland region called the Chicagoland COVID-19 Commons. A Gen3 data platform was set up and operated with policies, procedures and controls based upon NIST SP 800-53. A consensus data model for the commons was developed, and a variety of datasets were curated, harmonized and ingested, including statistical summary data about COVID cases, patient level clinical data, and SARS-CoV-2 viral variant data. Discussion and conclusion. Given the various legal and data agreements required to operate a data commons, a pandemic response commons is designed to be in place and operating at a low level prior to the occurrence of an epidemic, with the activities increasing as required during an epidemic. A regional instance of a Pandemic Response Commons is designed to be part of a broader data ecosystem or data mesh consisting of multiple regional commons supporting pandemic response through sharing of regional data. https://www.medrxiv.org/content/10.1101/2022.06.20.22276542v1?rss=1%22&utm_source=dlvr.it&utm_medium=tumblr Read more ↓

If you wish to keep away from having to pay for main repairs after a number of years, consider some ways to keep it in good condition. Step one to avoid major driveway repair is to maintain cracks small once they appear. Paving sealants are the materials that make a pavement last longer. poweraggregates It allows the pavement to look new all the time. This is a vital think about making our homes as stunning as we ever dreamt it to be. That is why we wish which are driveways or different parts of our home to have a paving sealant that may last longer. Due to this fact, we might try to search for such products which can be already examined by time and are actually prime-of-the-line. Think about if we've got the perfect product round. It can make our homes as lovely because it should at all times be. It will make our pavements look as all the time new as it is paved the primary time. When you've got ever been to a hospital, neighbor’s house or hospital, you will notice that the kind of flooring will differ. Polished floors make use of concrete sprucing that may be a ground substance polished to realize a sure look. Polished concrete is a really generic term that pertains to some decorative alternatives for flooring that end up leaving a concrete floor uncovered as the final final and last floor ending. The sharpening course of is very complicated, and it includes a number of technical points that include, making it dense, leveling, sharpening and sealing the floor whereas contained in the concrete floor. It has turn into a highly frequent thing in most of the locations all over the world because the general public recognize its beauty and likewise because several locations cannot stand having another varieties of flooring. There are lots of places the place concrete sprucing is used. Backyard fountains are the preferred decorative equipment used within the gardens that help enhance the ambiance manifold. Skilled craftsmen, dexterously design fountains that deliver peace and serenity in the setting. Lending an ornamental look to the backyard, fountains include attractive lightning techniques and coloured flowing water. They add particular character to the garden by beautifying its total look. Complimenting all kinds of backyard settings, the backyard fountains are carved out in variety of contemporary and traditional kinds and shapes together with - human figurines, saints, fairies, birds, animals, flowers as well as abstracts. To encourage probiotics from these dairy products to multiply even further, Huffnagle suggests consuming foods like spices, tea, crimson wine, berries, apples and beans. Not only should you minimize stress as a result of analysis teams at Wake Forrest University found that stress aggravates acne prone skin, but stress additionally weakens the colon the place probiotics have to work. Research has implicated chronic stress in the development of irritable bowel syndrome and in the worsening of inflammatory bowel illness signs. Moreover, stress sensitizes the intestine which will increase the likelihood of one more acne culprit-- growing allergies to sure foods.

Do not confuse poor high quality sheds with low cost sheds. Many of us who're discovering their houses merely aren't giant enough would like a fantastic shed but are concerned they only don't have sufficient funds to get a the shed they need. Effectively, whereas this could be true for some, but it's actually possible to construct cheap sheds if you don't thoughts placing within the work and taking your time to seek out supplies. There are a variety of choices to think about. You should buy some very low cost shed kits. Sadly, for many of those kits the emphasis actually is on "low-cost". If your home is a part of a home Homeowners Association (HOA), it is best to fastidiously look at your covenants, codes, and restrictions (CC&Rs). Your constructing may have to be authorized by the HOA board, previous to starting your mission. Some things they may consider are aesthetics, together with but not restricted to color, dimension, roofing materials, and landscaping surrounding the shed. When deciding on where you need to build your shed, consider its operate. Will you need a large door or a double door or particular access to the door, including a sidewalk or stepping stones? The Persian affect in backyard fountains was felt within the enclosure of the gardens and swimming pools, the structure of which had been meant to simulate the heavens. Many of these gardens inspired the famous Persian carpet designs that have persisted to this present day. Roman society was intricately tied to the bathing ritual, and particularly loved water options in the gardens intertwined with the public baths. In the recent deserts of the Center East, the desert oasis offered the inspiration for the historic Persian-impressed paradise gardens. Garden fountains harmonize water and are designed to meet both practical and aesthetic functions. Fountains embody symbolic, artistic and social concepts as they enliven locations and reinvigorate people. However not like sandstone is a much tougher material but manageable with a diamond blade. Bluestone comes in a large number of sizes and some fascinating patterns (Ashlar is a popular one!) Though not quite as mandatory as sandstone a good high quality sealer can also be a good suggestion. I tend to recommend a penetrating sealer with bluestone. Concrete pavers: Of all paving this kind had the widest vary in terms of color, sizes and patterns. This sort of paving is usually a low priced and quality paving (like C&M pavers) or a excessive priced/ high end paving (Anston paving is a good instance). The massive vary of concrete paving can be overwhelming, and i are likely to advocate the medium to excessive finish pavers (until you've gotten a tight price range in fact). Assume about color and magnificence and finances and that ought to help narrow your search down. See the outline of supplies which the sheds are manufactured from. If it is fabricated from wood, be certain that it is manufactured using industrial grade wood. In any case, a great selection can be steel mannequin as it's designed to last years.. Moreover, it is important to know what size is correct for all of your things that you simply want to retailer. So it's a must to record the gadgets that take up ground space in shed and measure their lengths and widths. Putting a shed together generally is a time-consuming process, so it is all the time sensible to observe installation instruction and equip your self with obligatory tools to do the job. Though steel sheds will be constructed sooner than wooden sheds, they don't include the natural attraction of wooden shed. With a wooden shed, individuals can recast the shed's look in response to their imagination and creativity. Once you perceive your needs, it's time for shopping. Typically, they can present in nearly any home hardware retailer.

The only good news about this whole, awful thing is when a pet owner pulls into the driveway they come home to their pets 100% of the time. — Mancipium Avem (@cis_76) November 28, 2017

Firstly there is the kind that has feminine connectors on two sides and male connectors on the opposite two sides. Typically talking, the female connectors are a sequence of loops which mesh with the pins on the other two sides. There are additionally tiles on the market which are successfully a technique connectors. Once you click the tiles into place, you can't simply elevate them up once more. Some manufacturers solely supply one design of deck tile, generally with four slats of wood working in the identical course. Generally there may be an option of a five or six slat tile. You may verify every measurement, not that you're going to have to, these are professionally drawn plans, but made for the absolute beginner. My Shed Plans Elite also comes with detailed full color illustrations and section drawings, some of the drawings are "cut away" views exhibiting exactly how all the pieces suits collectively, so you can't possibly get it mistaken.

Just how to Create a High Conversion Sales Video Clip (Component 1)

Absolutely nothing converts like an excellent video.

There are plenty of researches showing how efficient video clips go to turning visitors into customers. Definitely, video has actually been among the most valuable additions to my advertising toolbox and also I have actually been doing video clip for a long period of time.

However exactly what goes into making a high-conversion sales video clip? Exactly how do I tackle creating these video clips by VidSell and also what aspects are consisted of to see to it the video is involving, interesting as well as results in sales?

These are questions I obtain asked a lot as well as below is the most extensive solution I can give in a blog-post layout.

What you find below is a really detailed breakdown of my most recent sales video (one I made for a pre-release of a Thrive Themes product). The video clip was exceptionally effective, based on the conversion prices that were attained on this deal.

This is some extremely in-depth, nearly unfiltered behind-the-scenes insight right into just how I compose advertising and marketing messages. This is not fancy, not made for rapid usage and not dumbed down for blogging and very easy social shares. Just for the major. [/thrive_text_block] You can watch the full video by clicking on the web link listed below. Nonetheless, the individual components I'll be speaking about are all playable separately (simply click on the video clip strip heading photos), so I advise you watch each part, read the breakdown of it and after that maybe re-watch it.

Wish to see how they all meshed? View the whole video clip right here.

Component 1: I' ts Everything about the A

Focus, Interest, Desire, Action. AIDA is an advertising and marketing formula mentioned so usually, it is becoming a platitude. That does not make it less useful, though.

The first part of the video clip is a caution message and also it's everything about getting the visitors focus as well as stimulating their interest.

Harmonizing Act

Creating this component was a harmonizing act, due to the fact that I do not want to make the caution message as well severe or too tacky. In the sloppy waters of the "generate income online" niche, cautioning messages are usually utilized at the beginning of videos. The warning is normally extremely significant as well as totally severe on VidSell. Not to mention that it typically additionally includes some over-blown promises thrown in for good step.

Unlike this, I maintained my warning message short and the tone playful. My objective is to stimulate a "what is he yet?" response.

Favorable Organization & & Knowledge

For the layout, I attempted to make the slide look comparable to the "FBI Caution" titles that you in some cases see in motion pictures. This is a calculated choice. The association I'm going for is that what comes after that is something the visitor is enthusiastically eagerly anticipating seeing (like a new film).

Component 2: Preparing

The objective of the 2nd part is to establish the foundation. By the end of this component, the visitor ought to get on the very same web page as me and we ought to both recognize and also recognize what we are and also aren't talking about.

Rhetorical Questions

I open this area with a question: "Do you love WordPress?"

When you encounter a concern, your mind immediately engages and also you can't help however address the concern in your head. Rhetorical questions such as this can be made use of as a sly means to virtually require the audience's brain to react.

Dividing the Chaff from the Wheat

One more vital work this component has is to remove one of the most interested audiences in the audience: I make it clear that what I'm about to present is for individuals who use WordPress and also particularly people that use it regularly.

Whenever possible, do the filtering at an early stage in your message. This does two essential points:

For people who aren't in your target group, VidSell avoids losing their time. Think of if you enjoyed a tasty, 10-minute video about a brand-new item of software application, just to discover at the actual end that it's constructed for WordPress ... and you do not use WordPress. I 'd have wasted you time and also you would lose several of your rely on me. In every future message, you would certainly be supporting on your own for one more frustration.

For individuals who remain in your target group, it grows their engagement. When you involve a point that clearly claims "this is for you, however except those other individuals", you come to be extra committed to the message.

Briquetting plant consists from biomass grinder, screw conveyor and piston-press machine. The piston-press machine operates through open belt drive system. Pulley and belt system is an important part of the briquetting plant, which function is to transfer speed into reciprocating system. In this study, effect of slip and COF on belt life analysis has done through mathematical formulation and numerical simulation. Present study deals pulley simulation has done through help of Finite Element software ANSYS 12.0.1.

Keywords: ANSYS; Briquetting plant; COF; Pulley-belt; Slip

Introduction

We all are well known by the importance of energy and its sources. Energy is the key factor in economic development of every country. The demand of energy is increasing day by day and the supplies of sources are limited. It is globally red alert for fossil fuel like Petrol, Kerosene, Natural Gas, LPG, and Lignite etc. This has made a huge gap between the demand and supply of energy. Renewable energy is the ultimate solution, which can fill this gap.

The briquette is an alternate source of energy. The biomass briquettes are substitute for coal and L.P.G., and research is going on. The Biomass briquettes are made up of renewable source of energy.

The briquetting piston-press is a reciprocating crank type mechanical press with flywheel. The main motor through continuous flat belt drives flywheel. The ground material is feed through a hopper by means of a screw conveyer with its own motor. The vertical screw pre compresses and forces the material downward in to the feeding chamber. From the chamber the materials forced by the ram through a tapered die system on to the cooling track in the form of briquettes. Briquettes formed are cylinder shape. [1]

In this study, we discussing about belt drive-open system of piston-press machine. Belts are used when the distance between the axes of the two shafts to be connected is considerable. A flat belt is a belt with a narrow rectangular cross-section. The flat belts are easier to use and are subjected to minimum bending stress.

In the present paper, the pulley is simulated with ANSYS 12.0.1 Software. This way the concern of different process parameters such as coefficient of friction, power, thickness of belt, slip and tension on belt are studied.

Discussion of various parts

(Figure 1) Briquetting plant consists from various parts. The main part is as follows:

Biomass-grinding machine: It is an important part of the briquetting plant, which function is to convert aggregate material in to small pieces.

Screw conveyor: it is used to carry the raw biomass from storage place to hopper. It is also used to mix the moisture socking agent from the raw biomass.

Piston-press machine:

a) Hopper: Hopper is use to move the raw material from screw conveyor to processing place. It includes extruder which is used to give a motion to raw biomass only in a one direction.

b) Ram: Ram is used for forcing the raw biomass in a die holder. Ram is fixed in ram holder. These ram moves in a horizontal direction with the help of motor.

c) Collar: Collar is use to fix the die in a die holder. Also it is used for to prevent the flow of raw biomass in a wrong direction i.e. in motor direction.

d) Die: Die is the part where the briquette get the shape to from the briquette.

Cooling tower: After process of briquette formation it cool at cooling tower and move in a direction of storage place. [2]

In piston-press machine all the rotary as well as reciprocating parts moving through the pulley belt arrangement. Therefore, pulley belt system is very important part of briquetting plant. In this study, discussing about pulley and bet system of briquetting plant (Figure 2).

Aim of Study

The main aim of this study is to investigate:

a) Effects of coefficient of friction (COF)

b) Effect of different Belt thickness (t) on the quality of belt

c) Effect of tension (T) on pulley

d) Effect of slip (s).

Methodology

(Figure 3)

Input Data

Diameter of Driver d1=0.15 m;

Diameter of Follower d2=0.85m;

Speed of Drier N1=1475rpm;

Speed of Follower N2=?;

Power P=20kW;

Estimation of tension during rotation of driving pulley

A highly elastic belt is used for belt drive, which is operated by 15 hp electric motor and at the speed of driver & driven pulleys are 1475rpm & 260rpm, the diameter of driver & follower pulleys are 150 mm & 850 mm. Center to Center distance is 1.575m (Table 1).

Finite element simulation of pulley: Figure 4 showing FE model of pulley model prepared in ANSYS 12.0.1.

The 3-D FE model for pulley was created by using ANSYS 12.0.1 software. The shaft is analyzed in ANSYS in three steps. First is preprocessing which involves modeling, geometric clean up, element property definition and meshing. Next comes, solution which involves imposing boundary conditions and applying loads on the model and then solution runs. Next in sequence comes post processing, which involves analyzing the results plotting different parameters like stress, strain, natural frequency, harmonic frequency and many. The mesh has been generated using tetra free element. The Solid 45 element type is adopted to mesh the model. The mesh of the pulley consists of 83198 elements. 17492 nodes are included in the finite element model. [3-5].

Result & Discussion

Present study deal with coefficient of friction between belt and pulley and variation of thickness of belt. The stress analysis have done through numerical simulation which shown in Figure 5-7.

Figure 5 showing when the coefficient of friction between the belt and pulley has increase then the value of tension (slack side & tight side) will decreases. But both line follow same pattern. And also the 0.2 to 0.3 coefficient of friction will better value between belt and pulley.

Figure 6 showing when the thickness of belt increases also with increase of pulley diameter than the slip of belt increases. But, when the thickness of belt increases also with decrease of pulley diameter than the slip of belt decreases.

Figure 7 showing pulley simulation of piston-press machine, this simulation shows the total deformation of pulley. In this figure value of maximum deformation is 0.193E-04.

Figure 8 showing that the von-Mises stress and shear stress on the pulley periphery through simulation.

Figure 9 showing simulation results. In this graph of belt tension has analysed in terms of power. When the belt tight side tension has increased than the value of stresses (von-Mises stress, principal stress, shear stress) have follow same pattern, but the stress will also increasing.

Conclusion

a) Coefficient of friction has play major role in tensions on belt.

b) Change of belt thickness decrease as well as increase the slip of belt. Also the change in diameter of pulley affects the slip of belt.

c) The simulation is easily finding the stress on pulley that occurs due to belt tension.

How to Understand Fashiontech and the $2.4 Trillion Fashion Industry

Whenever an entire market obtains interrupted by 21st century modern technology, the tech obtains an obscure and also all-inclusive title. We already saw 'fintech' for the financial market. Currently, as the style world determines ways to deal with new technology, we have fashiontech.

So just what does fashiontech indicate? Is it also possible to damage down such a huge industry? The most recent forecast places the style world on track to $ 2.4 trillion globally this year, after climbing 3.5 percent over the previous year.

The Industry Is In Flux

The means people purchase clothing and invest in fashion patterns is moving: It's getting quicker, thanks to the fast turn over integral to the web world, as well as style providers are coming to be extra receptive as a result. Some platforms are relocating into the fashiontech world as well as leveraging their information by adding some kind of 'purchase' switches to preferred articles. Instagram is an all-natural fit, as is Pinterest. Here's how I discussed Pinterest's well-founded ecommerce future in a message in 2014:

' With these 3 new Pinterest features-- aesthetic search, a buying cart, and branded web pages-- the social media network is urging an uptick in all-natural look for items while providing a method for customers to acquire things they already want. Connecting individuals that intend to buy stuff with the stuff they intend to get is very unbeatable as an ecommerce design.'

Meanwhile, Amazon is again proving that it can quickly enter into any type of market it desires with a smart brand-new fashion-focused marketing design:

' The service-- called Prime Closet -- allows customers select from greater than a million products throughout guys's and females's fashion, in addition to baby garments. Consumers have to get at the very least 3 items on the reduced end, but could order approximately 15 pieces in a box. Maintain three or four products, and consumers save 10 percent. Keep 5 or even more and the discount boosts to 20 percent,' Recode clarified last month.

But the most significant changes don't have to be restricted to large business. Below's exactly how a start-up design can harmonize the industry.

The 3 Groups of Fashiontech

TechCo contributor Lisa Morales-Hellebo has actually composed a white paper on the emerging fashiontech financial investment landscape. There, she breaks down the fashiontech that matters into 3 primary classifications: data, supply chain, and future commerce.

' Information' describes technology that enables the sector to much better recognize and also track its customers' whims. Business in the fashiontech information arena may be in-store or on-line, as well as could provide customization to consumers or to retailers.

Meanwhile, those in supply chain help to simplify the layout, production, and circulation of the products themselves, and also those in the future of business innovate as well as try out entirely new ways to get in touch with audiences. A few fashion markets of the future include new data-powered markets like wearables as well as wise clothing. Taken with each other, these three locations of interest light the path that a business owner should require to prosper on the planet of fashiontech.

Go B2B

In fasion, B2C businesses have a difficult time making the acknowledgment from the general public that they require in order to prosper. But a B2B start-up, focused in one of the three primary groups of fashiontech, can swiftly grow. Why? Since style firms could review the creating on the wall as well as understand they'll have to advance with their market. They know the three groups over, also if the normal consumer does not. As Morales-Hellebo places it:

"Mature industries never ever obtain the chance to rearrange from square one, yet this may be style's best chance. Fashion's digital renaissance, as it might come to be understood, is being constructed before our eyes, as well as we have an unique possibility to re-engineer just how all its components meshed in a manner that prevents future uncomfortable retrofitting (conserving us all time, energy, brain power, and cash). "

It's a great time to be in fashiontech. Whether you're a B2B business owner or an investor checking out the fashiontech market, knowing the 3 essential pillars of style disruption will open the world of fashiontech as much as you.

The Cloud Expedition: Movement of Databases to the Cloud

The incorporation of the cloud by modern business is readily on the rise. Realizing the ever-increasing demands of businesses, enterprises are investigating more and more cloud capabilities for revolutionizing businesses and, thus looking up to cloud architectures. The increased shift to cloud computing is giving way to a mammoth digital transformation and as per predictions, the spending on cloud services will go up to $160 billion by the end of 2019. Cloud technology will streamline businesses by renovating legacy databases, simplifying access, creating more organized file backups and threat recovery, etc.

Oracle has made ten anticipations for 2019 regarding cloud computing. These predictions are as follows:

Hundred percent data-centre replacement is going to be allowed by 2nd generation cloud providers

Eighty percent of company workloads will shift to the cloud.

Every application will be AI integrated, thus further moving away from legacy applications.

Artificial Intelligence, along will other growing technologies, will be doubling productivity.

Eighty-five percent of customer communications will get automated.

The expansion of the developer community is anticipated to be about 10x, with productivity growing by four-hundred percent.

There will be automated management of more than fifty percent of the data.

A single identity platform will be incorporated by ninety-percent of enterprises, and this platform will link the premises and the cloud.

The security events' number will progress to 100× and automation will be the most trusted means of checking and eliminating threats.

There will be complete automation of seventy percent of IT enterprises.

The Perks of Shifting Databases to the Cloud

A huge chunk of the IT is making way to cloud computing. The obvious reasons are reduced costs, higher flexibility, stupendous scalability, higher reliability, great security, reduced costs of maintenance, etc.

By migrating to the cloud, businesses get the advantage of reducing the maintenance costs to a massive extent. Every cloud migration strategy brings down the capital expenditures for too many software and hardware. Besides this, the operational costs of enterprises are also negated. These operational costs may include costs of installation, maintenance, patching, updating, etc.

The flexibility offered by cloud computing is excellent. For instance, if a company plans to build a dev environment with a database, this can be built instantly, with developers beginning to work on it in no time with automated up-scaling and down-scaling. Such scalability guarantees that the requirements and supplies are harmonized.

The Remarkable Journey of Modern Businesses:The Shift to the Cloud

Cloud suppliers enable seamless running of data centers with almost zero chances of failure, thus ensuring greater reliability of cloud services. Also, when we are considering the security factor, security within the cloud network can be much greater than the on-premises network security. Data is the most vital aspect within the cloud, and keeping it secure is the highest priority of the cloud suppliers. Cloud providers guarantee superior data encryption, using enhanced techniques to guard the cloud data from any kind of risk or threat. This may include security tracking, white-hat testing, etc.

It must be kept in mind that shifting to the cloud is beneficial and complex at the same time. Thus, before considering any cloud migration service, it is always necessary to understand the business requirements and the potential challenges.

Overcoming Downtime

There is the risk of a considerable downtime while moving to the cloud. For example, there might be a requirement to halt all user inputs, export the current database and then import the same to the new cloud-based database. This can be time-consuming and result in prolonged downtime. However, this problem can be eliminated with advanced migration tools, along with proper planning and systematic management of risks. Some amount of downtime cannot be avoided, however, the overall downtime period can be largely reduced. Coordination is achieved between the old and new databases and users can smoothly migrate their working from traditional to the cloud. The current system’s data must be kept accessible during the set up of the new cloud-based system.

It is thus quite evident that the pros of cloud shift are much greater than the cons. It is no wonder that cloud migration, Texas is gaining huge momentum.

The Way to Smoothly Shift Databases to the Cloud

Cloud migration can have various approaches and strategies. It is advisable to choose the right strategy before choosing the cloud. It has to be rightly identified, what is actually expected from the cloud. An enterprise can decide to build new applications with a new cloud-based database and plan not to shift the old databases at all. Here, the on-premises database and cloud technology exist side by side. Some organizations may plan the move the complete on-premises database to the cloud, all at once, in a quick time span, say, in a weekend. However, this may involve high risks, which may lead to lengthened downtime.

Enterprises are recommended to migrate their databases by recognizing lower influence tables like development, Quality Assurance databases, data integration and disaster recovery use cases, etc. that need the data to be available, without intervening with application uptime. Enterprises may also recreate on-premises database information on the targeted cloud-based database.

Whatever be the path of cloud migration, systematic planning is extremely crucial for successfully shifting legacies to the cloud, negating disturbances in the workflow. Activities operating on the database should not get affected before, during or after the cloud shift.  Choosing the right cloud migration techniques is highly essential.

According to the Forrester report, in 2019, the biggest public cloud suppliers will get even greater and cloud spending will swell. The 6 renowned cloud adopters — Amazon Web Services, Microsoft Azure, Google, IBM, Alibaba, and Oracle — will become more enhanced in 2019. The worldwide market of cloud computing, which includes cloud-based platforms, enterprise services, and SaaS, will surpass $200 billion in 2019. Statisa has estimated that the public cloud services market revenue will transcend 278.3 billion U.S. dollars by 2021.

This is a bit outdated preview of a pixar's harmonic coordinates deformer made with ICE.

It deforms target geometry by points of a closed triangular cage mesh with influence distributed in a volume of a cage.

First cage mesh is filled with grid of points. Then barycentric coordinates are calculated for boundary points. Later those coordinates are diffused in volume with fixed boundary values. The slice plane shows gradient representation of weight distribution in volume for corresponding point. In this example one frame makes one diffusion iteration. After desired iterations reached data is cached and then loaded to separate point cloud for binding. Binding is done dynamically with trilinear interpolation from 8 surrounding grid points.

This method can be used to calculate skin weights. In given example scene cage points are represented as envelope deformers with harmonic coordinates used as skin weights. With skinning results are the same as with harmonic coordinates deformer, but now target mesh can be exported to game engine with smooth deformations (deformer limit should be considered though).

Here is scene file with deformer and cache file of calculated data. https://www.dropbox.com/s/6jrant88ksjypen/harmonicCoordinatesSimple_01.scn?dl=0 https://www.dropbox.com/s/o6jpimp0t77hcto/trexHC_1.icecache?dl=0 To play with this scene copy cache file to Simulation folder of current project or point out that cache file in hcRead point cloud ICE tree .

New Post has been published on http://engineer.city/mesys-software-version-07-2019-is-available/

MESYS Software Version 07/2019 is available

Version 07/2019 of MESYS Shaft and Bearing analysis software is now available under Downloads and provides additional functionality.

General Extensions

The parameter variation now allows an additional optimization step. For example, the maximum permissible radial force can be calculated for each case dependent on different criteria.

Data points of diagrams can now by exported in XLSX format. The curves can also be copied from one diagram into another, this can be used for comparison of results.

Some additional methods were added to the COM interface. For example, a method to retrieve the stiffness matrix of bearings and ball screws.

Extensions in the Bearing Calculation

The bearing databases from Schaeffler and SKF are updated to latest data from the manufacturers. These only contain catalog data. The internal geometry is approximated by the software. A new database from HQW Precision GmbH is added containing spindle bearings up to 30 bore diameter. This database contains internal geometry provided by HQW and the internal geometry is hidden. Further databases with internal geometry are available from GMN, IBC and CSC on request from the manufacturer.

Three-point bearings were added as bearing type. They have one full radius on one race and two radii like in four-point bearings on the other race. The load capacity is calculated based on angular contact bearings using the free contact angle.

An additional option for roller profiles was added allowing the input of two tangential radii.

Gyroscopic moments can now be considered on all ball bearing types including four-point bearings, where it was not supported before.

Extensions in the Shaft Calculation

A background drawing can by added by pasting it from the clipboard. Then the shaft geometry can be drawn as a polygon. This can be used if shaft geometry was just provided as a PDF. The CAD import as DXF or STEP now also allows a rotation of the drawing in case the shaft axis is not the x-axis.

Harmonic response can now be calculated on periodic displacements in addition to periodic forces. Excitations can be defined for supports connected to the rigid environment. They can also be defined for bearings based on inner or outer ring rotation or for gear mesh frequencies of cylindrical gears.

For planetary gear stages the results are now reported for supports of all planets and also the results for all gear pairs are provided. They were calculated before but not available in the standard report or result overview. The results for different planets can be different in case additional forces are applied to planet carrier or the rings gear.

For 3D-elastic parts with elastic bearings, now contact between bearing ring and part can be considered. The fitting is then considered in the contact model instead in the operating clearance of the bearing.

It is now possible to consider centrifugal expansion on 3D-elastic parts. Additional new features for 3D-elastic parts are new possibilities for mesh import and mesh export. Also new faces for connection with supports can now be defined directly within the software.

3D imaging reveals hidden history in old shells

High-resolution 3D imaging and new geometric deep learning approaches are revealing a fuller version of the story hidden in shells, researchers report.

A clam shell may be a familiar find on the beach, but its intricate curves and markings tell a rich tale. For centuries, biologists have collected, drawn, measured, and compared the shells of bivalve species, pursuing knowledge about how the environment and behavior shape biodiversity.

Over the last two years, David Jablonski’s research group has moved into the third dimension, using a campus micro-CT scanner to create 3D images of more than 3,000 shells from clams, oysters, mussels, and other members of the bivalve class scientists and museums around the world have collected.

This growing database will allow scientists to ask deeper questions about biodiversity both between and within species, and how climate change might affect the survival, distribution, and shape of organisms with ecological, economic, and dietary importance. But fully realizing the potential of the new data will require novel and advanced techniques for measuring, analyzing, and comparing shell features.

“The challenge to all this is how to capture those morphologies quantitatively in a way that lets us say something concrete about the distribution of form in time and space,” says Jablonski, a professor in the geophysical sciences department at the University of Chicago. “As you can imagine, it’s really hard to compare these three-dimensional shells to one another in any rigorous way.”

Injecting geometry into deep learning networks

That need led to a partnership with Tingran Gao, an instructor in the statistics department. Gao’s research focuses on learning and understanding the geometry and topology of high-dimensional data sets, especially those arising from social and natural sciences. Recently, Gao developed geometric learning frameworks to analyze 3D scans of complex biological surfaces such as primate bones and teeth.

The shell database provided a unique opportunity to adapt and expand that line of work in a new biological context, as well as to push the boundaries of geometric deep learning and develop new methods for tackling emerging computational and statistical challenges.

“These shells have many geometric features that don’t exist in primate shape data, which tend to be more smooth and relatively easier to handle,” Gao says. “Shells, unlike bones or teeth, are not covered by soft tissue; instead, they are directly exposed to external environments and thus encode more ecological information. Their curved external surfaces are often covered with characteristic geometric patterns and textures, which are central objects of study in applied and computational harmonic analysis.”

Deep learning, the machine learning approach that utilizes algorithms known as neural networks, provides several advantages in addressing these challenges. As recent advances in computer vision show, deep learning excels at making sense of high-dimensional data and sophisticated structures. Instead of the traditional practice of choosing physical characteristics of the shells to measure and compare, deep learning can mathematically extract the most relevant features that distill rich information about morphological differences and, more broadly, the nature of biodiversity.

From old collections, new knowledge

The ideal end result will be a trained model that allows researchers to interrogate the unseen mechanisms driving biodiversity, trace the path of evolution through reanalyzing fossil specimens, and make predictions about the future of bivalve species, Jablonski says. For example, scientists can study the biological trade-offs bivalves make between investing in a tougher, more elaborate shell or growing the soft tissue within, and how different environments or modes of life affect that balance.

“What we want to do is ask questions about how those knobs are twiddled by the organisms as they confront different climate zones or predation intensities or, for that matter, how that varies among lineages that are economically important versus lineages that aren’t,” Jablonski says.

“The association between the surface textures and the ecology has never been accessible, because no one has ever really been able to quantify in a rigorous, reproducible way the huge variety of surface structures that there are.”

The researchers will share image and mesh data from the project through open resources such as the digital repository MorphoSource. The deep learning and morphometrics communities will benefit from new approaches that bridge these shape disparities with geospatial information, Gao says. Beyond bivalves, these approaches have the potential to extract new knowledge from species across the Tree of Life, and bring fresh scientific value to specimens archived in museums.

“Who would’ve dreamed when some of this stuff was collected in the 19th century what it would be used for?” Jablonski says.

“Technology is always creating new ways to learn new things about museum collections that go back centuries. That’s one of the joys of being involved with this kind of work, diving into those biological archives to weave together species, ecology, and form.”

Funding for the research came from a seed grant from the University of Chicago’s Center for Data and Computing.
