How does an engine contribute to a car's powertrain?

The powertrain in a vehicle is the system responsible for generating power and delivering it to the wheels to propel the vehicle forward. The operation of a powertrain can vary depending on whether the vehicle is powered by an internal combustion engine (ICE) or an electric motor (in the case of electric vehicles). Here's a general overview of how a powertrain works in both types of vehicles:

Internal Combustion Engine (ICE) Vehicle - Combustion Process: In an ICE vehicle, the powertrain starts with the combustion process in the engine. Fuel (gasoline or diesel) mixes with air in the combustion chamber and is ignited by spark plugs (in gasoline engines) or compression (in diesel engines).

Power Generation: The combustion process generates energy in the form of mechanical power, causing pistons to move up and down within the cylinders of the engine. This motion drives the crankshaft, converting linear motion into rotational motion.

Transmission: The rotational motion from the crankshaft is transmitted to the transmission, which consists of gears that allow the driver to select different ratios (speeds). This enables the engine to operate efficiently across a range of vehicle speeds.

Drivetrain: The transmission sends power to the drivetrain components, including the driveshaft, differential, and axles, which transfer power to the wheels. The differential allows the wheels to rotate at different speeds, enabling smooth turns.

Wheel Movement: The power transmitted through the drivetrain causes the wheels to rotate, propelling the vehicle forward or backward depending on the gear selection and throttle input from the driver.

Electric Vehicle (EV) -

Battery Pack: The primary source of power for the EV, storing electricity in chemical form.Powers the electric motor and provides electricity for all electronic devices within the EV.

Battery Management System (BMS): Monitors battery cell conditions, including voltage, current, temperature, and state of charge (SoC).It protects the battery against overcharging, deep discharging, and overheating and helps balance the charge across cells. Ensures optimal performance and longevity of the battery by regulating its environment.

Inverter: Converts DC from the battery pack into AC to drive the electric motor.Adjusts the frequency and amplitude of the AC output to control the motor’s speed and torque. Critical for translating electrical energy into mechanical energy efficiently.

Onboard Charger: Facilitates the conversion of external AC (from the grid) to DC to charge the battery pack. Integrated within the vehicle, allowing for charging from standard electrical outlets or specialized EV charging stations. Manages charging rate based on battery status to ensure safe and efficient charging.

DC-DC Converter: Steps down the high-voltage DC from the battery pack to the lower-voltage DC needed for the vehicle's auxiliary systems, such as lighting, infotainment, and climate control. Ensures compatibility between the high-voltage battery system and low-voltage electronic components.

Electric Motor: Converts electrical energy into mechanical energy to propel the vehicle. It can be of various types, such as induction motors or permanent magnet synchronous motors, each offering different efficiencies and characteristics. Typically provides instant torque, resulting in rapid acceleration.

Vehicle Control Unit (VCU): The central computer or electronic control unit (ECU) that governs the EV's systems. Processes inputs from the vehicle’s sensors and driver inputs to manage power delivery, regenerative braking, and vehicle dynamics. Ensures optimal performance, energy efficiency, and safety.

Power Distribution Unit (PDU): Manages electrical power distribution from the battery to the EV’s various systems. Ensures that components such as the electric motor, onboard charger, and DC-DC converter receive the power they need to operate efficiently. Protects the vehicle's electrical systems by regulating current flow and preventing electrical faults.

In both ICE vehicles and EVs, the powertrain's components work together to convert energy into motion, enabling the vehicle to move efficiently and effectively. However, the specific technologies and processes involved differ significantly between the two propulsion systems.

Drive-by-wire design

Introduction

Over the past few decades, the automotive industry has seen a significant upheaval, driven by technical advancements that have led to a move away from conventional mechanical systems and toward sophisticated electronic solutions. Drive-by-Wire (DBW) technology stands out among these advancements as a game-changer, revolutionizing the way contemporary cars function and providing a host of advantages along with some special difficulties.

What is drive-by-wire technology?

Although electronic throttle control systems are the main application for drive-by-wire (DBW) technology, they can also be used for other vital vehicle systems like steering and braking. To manage vehicle functions, DBW essentially substitutes electronic sensors, actuators, and controllers for conventional mechanical connections.

When the accelerator pedal is depressed in a traditional mechanical system, a cable attached to the throttle body is pulled, opening the throttle to let more air into the engine. On the other hand, DBW systems accomplish the same goal by using electrical impulses. Sensors identify the position of the accelerator pedal as it is depressed, and an Electronic Control Unit (ECU) receives this data. After processing the data, the ECU instructs an actuator to modify the brakes, steering, or throttle as necessary.

Important Drive-by-Wire System Elements

The main parts of a conventional throttle drive-by-wire system are as follows:

Accelerator Pedal Position Sensor (APP): The accelerator pedal position sensor (APP) gauges the amount of pressure applied to the accelerator pedal. To ascertain the driver’s intended action, the ECU receives data from the sensor.

Vehicle Control Unit (VCU): Often called the “brain” of the system, the VCU interprets sensor data, decides what to do, and orders actuators. To guarantee accurate control, the throttle position sensor (TPS) keeps track of the throttle valve’s position and feeds feedback to the VCU.

Throttle actuator: A servo or electronic motor that, in response to commands from the VCU, modifies the position of the throttle valve.

Drive-by-Wire Systems’ Advantages

DBW systems have many benefits over conventional mechanical systems, including:

Precision and Management:

Vehicle functions can be precisely controlled using DBW systems. It is possible to fine-tune electronic signals to react to driver inputs more rapidly and precisely.

Enhanced Fuel Efficiency:

DBW systems improve combustion and fuel efficiency by more effectively maximizing the air-fuel ratio.

System Integration:

DBW systems enhance overall vehicle performance and safety by smoothly integrating with other vehicle control systems, such as cruise control, traction control, and stability control.

Adaptive Qualities:

Adaptive features like changeable steering sensitivity, throttle responsiveness, and gear shifting according to driving situations are made possible by these systems.

Decreased Complexity of the Mechanical System:

DBW systems simplify vehicle design by doing away with parts like throttle cables, which may save production costs and maintenance needs.

Improved Safety Features:

To increase vehicle safety and stability, DBW technology complements safety features including electronic stability control (ESC) and anti-lock braking systems (ABS).

Personalized Driving Modes:

Remote Maintenance and Diagnostics:

Manufacturers can find problems, update software, and increase maintenance efficiency with the use of DBW systems’ remote monitoring and diagnostic capabilities.

Weight Reduction:

Vehicle weight is decreased by removing mechanical parts like throttle cables, which enhances handling and fuel economy.

Advanced Driver Assistance System (ADAS) compatibility:

ADAS technologies like adaptive cruise control, lane-keeping assistance, and autonomous driving depend on DBW systems.

The drawbacks and difficulties of drive-by-wire systems

Although DBW systems have several advantages, engineers, and manufacturers must also overcome the following issues:

Redundancy and reliability:

Potential failure spots are introduced by the dependence on numerous electronic components. Putting redundant systems and fail-safe measures in place increases complexity and expense.

Risks to Cybersecurity

Due to their electronic control, DBW systems are susceptible to hacking. Strong cyber security defenses are necessary to stop illegal access and manipulation.

Driver Disconnect:

Traditional mechanical systems’ tactile feedback is preferred by certain drivers. DBW systems might not have the “feel” that fans anticipate.

Increased expenses for implementation:

Compared to typical systems, DBW systems have greater initial expenses. Specialized equipment and knowledge may also be needed for maintenance and repairs.

Diagnostic Difficulties:

Electronic system diagnosis and repair can be difficult and call for specialized knowledge and tools.

Dependency on Power:

A dependable power source is necessary for DBW systems. Even with backup mechanisms in place, essential vehicle functions could be jeopardized by an electrical failure or power loss.

Enthusiast’s worries:

The mechanical responsiveness of conventional systems is frequently preferred by auto enthusiasts, especially in sports or performance vehicles.

Impact on the Environment:

There may be environmental effects from the manufacture and disposal of electronic components, which frequently involve rare earth elements.

Problems with Compatibility:

Compatibility issues might make it difficult to upgrade or replace parts of a DBW system, particularly when it comes to aftermarket modifications.

The learning curve

Conclusion

Drive-by-wire technology is a major advancement in the functionality and design of automobiles. By substituting electrical technologies for mechanical parts, DBW provides unmatched accuracy, effectiveness, and versatility. The potential of DBW systems to influence transportation in the future is further highlighted by their integration with cutting-edge safety features and driver support technology.

However, to guarantee broad adoption and long-term success, issues like cost, cyber security, and dependability must be properly handled. DBW systems are positioned to be crucial to the development of contemporary automobiles as long as manufacturers keep coming up with new ideas and solving these problems.

Introducing Google Axion Processors: A New Era for Cloud

Google Axion Processors

Arm Based CPU

At Google, they continuously push the limits of computers to investigate what can be done for big problems like global video distribution, information retrieval, and, of course, generative AI. Rethinking systems design in close cooperation with service developers is necessary to achieve this. Their large investment in bespoke silicon is the outcome of this rethinking. Google is excited to present the most recent iteration of this effort today: Google Axion Processors, Google’s first specially made Arm-based CPUs intended for data centers. Later this year, Axion which offers performance and energy efficiency that leads the industry will be made accessible to Google Cloud users.

Axion is only the most recent model of customised silicon from Google. Google’s first Video Coding Unit (VCU) increased video transcoding efficiency by 33x in 2018. Five generations of Tensor Processing Units have been launched since 2015. Google invested in “system on a chip” (SoC) designs and released the first of three generations of mobile Tensor processors in 2021 to boost bespoke computing.

General-purpose computing is and will continue to be a vital component of their customers’ workloads, even if Google investments in compute accelerators have revolutionised their capabilities. Extensive computation power is needed for analytics, information retrieval, and machine learning training and providing. The pace at which CPUs are being improved has slowed lately, which has affected customers and users who want to satisfy sustainability objectives, save infrastructure costs, and maximise performance. According to Amdahl’s Law, unless Google make the corresponding expenditures to stay up, general purpose compute will dominate the cost and restrict the capabilities of their infrastructure as accelerators continue to advance.

Google BigTable

In order to deliver instances with up to 30% better performance than the fastest general-purpose Arm-based instances currently available in the cloud, as well as up to 50% better performance and up to 60% better energy-efficiency than comparable current-generation x86-based instances, Axion processors combine Google’s silicon expertise with Arm’s highest performing CPU cores. For this reason, on current generation Arm-based servers, Google have already begun implementing Google services such as BigTable, Google Spanner, BigQuery, Blobstore, Pub/Sub, Google Earth Engine, and the YouTube Ads platform. Google also have plans to deploy and expand these services, along with others, on Axion shortly.

Superior effectiveness and performance, supported by Titanium

Axion processors, which are constructed around the Arm Neoverse V2 CPU, offer massive performance gains for a variety of general-purpose workloads, including media processing, web and app servers, containerised microservices, open-source databases, in-memory caches, data analytics engines, and more.

Titanium, a system of specially designed silicon microcontrollers and tiered scale-out offloads, provides the foundation for Axion. Platform functions like networking and security are handled by titanium offloads, giving Axion processors more capacity and enhanced performance for workloads from customers. Titanium also transfers I/O processing for storage to Hyperdisk, Google’s recently launched block storage solution that can be dynamically supplied in real time and decouples performance from instance size.

Titanium

A system of specially designed silicon security microcontrollers and tiered scale-out offloads that enhances the dependability, security, life cycle management, and performance of infrastructure.

Google-powered Titanium

Titanium is a free platform that supports Hyperdisk block storage, networking, the newest compute instance types (C3, A3, and H3), and more on Google Cloud.

Included in the system are:

Titan security microcontrollers are specially designed to provide Google Cloud’s infrastructure a hardware root of trust.

Titanium adaptor: specialised offload card that offers hardware acceleration for virtualization services; frees up resources for workloads by offloading processing from the host CPU

Titanium offload processors (TOPs) are silicon devices placed across the data centre that are used as a scalable and adaptable method of offloading network and I/O operations from the host CPU.

Enhanced functionality of the infrastructure

Titanium offloads computation from the host hardware to provide additional compute and memory resources for your applications.

Hyperdisk Extreme block storage allows for up to 500k IOPS per instance, which is the greatest among top hyperscalers.

200 Gbps or more of network bandwidth

Full line rate network encryption that offers security without compromising speed

Consistent performance comparable to bare metal for the most delicate workloads

Smooth management of the infrastructure life cycle

Infrastructure changes are made easier by Titanium’s modular hardware and software, which also provide offloading capabilities and workload continuity and security.

Advanced maintenance controls for the most critical workloads and seamless upgrades for the majority of workloads

It is possible to start remote infrastructure upgrades from any location.

The Titanium adaptor’s dedicated domains for networking and storage enable for the autonomous upkeep and upgrades of individual services, keeping them apart from the host’s burden.

“Building on Google’s high-performance Arm Neoverse V2 platform, Google’s announcement of the new Axion CPU represents a significant milestone in the delivery of custom silicon optimised for Google’s infrastructure.” The greatest experience for consumers using Arm is guaranteed by decades of ecosystem investment, Google’s continuous innovation, and its contributions to open-source software.”

Customers want to accomplish their sustainability objectives and operate more effectively, not only perform better. In comparison to five years ago, Google Cloud data centres are now 1.5 times more efficient than the industry average and provide 3 times more processing power with the same amount of electrical power. Google lofty objectives include running their campuses, offices, and data centres entirely on carbon-free energy sources around-the-clock and providing resources to assist with carbon emission reporting. Customers may optimise for even greater energy efficiency using Axion processors.

Axion: Interoperability and compatibility with out-of-the-box applications

Additionally, Google has a long history of supporting the Arm ecosystem. They worked closely with Arm and industry partners to optimize Android, Kubernetes, Tensorflow, and the Go language for the Arm architecture. Google also constructed and made them open-sourced.

Armv9 architecture

The standard Armv9 architecture and instruction set serve as the foundation for Axion. Google have made contributions to the SystemReady Virtual Environment (VE) standard, which is designed to ensure that Arm-based servers and virtual machines (VMs) can run common operating systems and software packages. This standard makes it easier for customers to deploy Arm workloads on Google Cloud with minimal to no code rewrites. Google is gaining access to an ecosystem of tens of thousands of cloud users that are already using Arm-native software from hundreds of ISVs and open-source projects and deploying workloads thanks to Google’s partnership.

Axion will be available to users across a variety of Google Cloud services, such as Cloud Batch, Dataproc, Dataflow, Google Compute Engine, and Google Kubernetes Engine. The Google Cloud Marketplace now offers Arm-compatible apps and solutions, and Google just released preview support for the Migrate to Virtual Machines service, which allows you to migrate Arm-based instances.

[sparkler-v]

Thankfully it was only a few pages back into recent documentation that she found a detailed sketch of a familiar object. The dark lantern that contained Sparkler's core, though in this sketch it held what looked to be a wispy spirit with a deeply woeful expression.

The Virus Containment Unit, VCU for short, is a device that is designed to fulfill its namesake. Securely contain a virus that lacks physical form, in order to safely preform removal procedures from programs they have negative impact upon. Due to the nature of energy based virus' and potential risks of transporting one, these devices are constructed to be completely airtight and virtually indestructible. Which brings to question, should Sparkler somehow bumble her way into this device how would we go about releasing her so we may properly ridicule her stupidity.

(She should know better then to reactivate the security measures that would lead to this. I will be properly annoyed if she does.)

The first solution is also the most straight forward. Release her using the computers in Hyrule's remote security room, located beneath Kakariko Village. Specifically in the tunnels located beneath Impa's hut, and in the mountains behind it. Of course while this is the most straight forward method, it is also the most dangerous to Sparkler's being. As once the VCU is connected to the computer via plug in insert, total access to her code is given. While we possess many trustworthy allies in our group who would simply free her with the device. I simply will not recommend this method until Lan's occupation of Kakariko has ended. Thus preventing potential risks to Sparkler's being should plans to free her using this method fail.

This leads me to consider our second solution, which is to locate the key for opening VCUs in the event of one locking by mistake. This key is known to be in the possession of the Head of Security. Which I refuse to believe the identity of is Lan, no matter how much he claims to be. No, Monk Maz Koshia is the one who truly owns that title. It would be a matter of then of reaching him in the Final Trial in order to explain our case of releasing Sparkler from the unit. However, all attempts I have made to establish contact have failed thus far. This is likely due to the ramifications of Lan's meddling with the entrance of our world. Seeking contact with Monk Maz Koshia may unfortunately be a trail of its own.

There is one other solution that I have considered, though it is based on theory rather then on any solid evidence. It is not one I wish to dwell upon, though if we are desperate... I should at least record my theories and hope nothing comes from them.

The page ended there, though the entry clearly continued on the next one.

Zelda nodded, already opening the book and starting to search... though she did step over to Riju's couch and sink down onto the cushions.

The sooner they found how to free Sparkler, the sooner they could give Link a little peace of mind...

Sprint 2 Overview

Sprint Recap: 

To recap what our group did, we found out there are different transportation needs for different contexts, for different needs, students want to see different information, and Info on popular map/navigating apps is inaccurate or doesn’t display the info students wish to see. This research has allowed us to see that in order to achieve an objective the issue that needs to be addressed is access to information. I was responsible for finding out the preferred & available transportation options in RVA and also analyzing the navigation apps. 

I was able to figure this out using a Reddit poll posing as a VCU freshman in need of advice, I was able to analyze and identify the preferred transportation method. It gained 170 votes in total and gave a different result from the last Sprint

In analyzing the reviews of 5 apps related to navigation, I found most of them suffer from not meeting the need for the best accuracy, reliability, and generally being up-to-date for the people, some worse than others.

Next Sprint Plan:

For the next Sprint, We as a group will be working on the prototype for the solution to the problem statement. We are given a task to complete for the overall prototype.

Reflections:

The Sprint taught me that data collection must be prioritized and a specific audience must be targeted to better understand the topic. Additionally, the results may differ when sourcing data from a different audience. I’ve also learned that I need to be able to explain the findings in a short and easily understood way. 

For the rest of the project, The prototype will have to be something that’s able to solve everything the student finds issues with planning trips from the last two Sprints.

Sprint 1 Overview

Introduction:

Richmond is a city known for its walkability. Compared to other United States cities, Richmond has an impressive sidewalk network that makes getting from one neighborhood to another relatively easy. Sidewalks won't end in the middle of the road and everything is a short distance away from each other. It seems almost perfect until you realize the condition of these sidewalks. Missing chunks and misaligned pieces of brick litter the sidewalks surrounding Richmond. Areas near the VCU campus especially have very rough sidewalk conditions. The current conditions could pose a real danger to pedestrians who could easily trip and get hurt if they weren't looking too closely. Our goal as the Sidewalk Surgeons is to figure out a solution to make the RVA sidewalks less hazardous for pedestrians by researching, documenting, and interviewing the people of Richmond. 

Sprint Recap: 

For our first Sprint, our goal was to research basic information about the Richmond sidewalks such as who owns them, who repairs them, their legal protections, how long they've been in this condition, and more. We then focused on interviewing, polling, and observing the residents of Richmond/VCU to see if they've had any troubles caused by the sidewalk conditions and if sidewalk repair was a problem they cared about. Observations showed that a lot of pedestrians were struggling to walk on the Cathedral Place sidewalks. We focused the most on the Cathedral Place sidewalks because of the intense damage they displayed. We determined that the Bishop of the Cathedral of the Sacred Heart is in charge of repairs to that specific sidewalk. We also looked into ways to repair the sidewalks and the legality and likelihood behind each method. We determined that repairing the sidewalks might pose problems because they are historically protected and we might not be allowed to alter them.

My goals during this first Sprint were to research who was in charge of the sidewalks around different parts of Richmond, learn how to request repair for the sidewalks, and see if and how VCU students were affected by the damaged sidewalks. The first thing I did was research who was in charge of the sidewalks in the Richmond area. This brought me to the City of Richmond's website, clarifying that two companies repair Richmond sidewalks. Roadway Maintenance takes care of project areas smaller than half a block while Capital Projects Management manages larger projects. This page also included ways to inform the City of Richmond about damaged sidewalks such as their Customer Care number and a request form known as RVA311.

My next step was to email VCU's Facility Management to find out who was in charge of VCU's sidewalk repairs. I didn't receive an email back during the first Sprint but received a response two days ago. I will be including this in the second Sprint since they emailed me back after the first Sprint.

I also emailed the City of Richmond asking questions such as how often they repair sidewalks, if they have any plans to repair sidewalks surrounding Cathedral Place, and more. I have not received an answer from them yet. 

To see if VCU students were being bothered by the current condition of the sidewalks, I decided to put up a poll on the VCU subreddit. I asked the students on the subreddit if they had been negatively affected by VCU's damaged sidewalks. I made this poll a simple Yes or No response and told people to comment their thoughts. The results I got back included 27 people voting Yes and seven voting No. Only one person commented specifics about their negative experiences with VCU’s sidewalks. They said that in their experience, the city-maintained sidewalks were worse than those adjacent to VCU property. They said they could usually count on VCU sidewalks being more accessibility-friendly and that at least VCU uses an angle grinder to smooth out their uneven sidewalk sections. At this point in the research, we hadn't considered that a lot of the sidewalks we considered unsafe could be owned by the City of Richmond rather than VCU. Perhaps, this wasn’t a problem with VCU’s legislation like we originally thought. 

After this initial poll, a moderator for the VCU subreddit suggested that I make the poll more specific and add whether people are getting injured and the severity of said injuries. The new options I added include I have had a sidewalk incident that had no injuries, I had a sidewalk incident that resulted in minor injuries, I have not had any issues with the sidewalks, I have had a sidewalk incident that resulted in damage to property (cell phone, bike, etc.), and an option to put extra details in the comment section of the post.

The moderator pinned my poll in the subreddit to ensure people were able to see it. I deleted my old poll because the new one had more specific information. The only photographic evidence of it I have are the two images above.

When the poll was over, 111 people voted. 44 said that they had a sidewalk incident that led to no injury, 18 said they had a sidewalk incident that resulted in minor injury, 40 said they had no issues with the sidewalks, six said that they had an incident with the sidewalks that led to damage to their property, and three people put specifics in the comment section.

The first commenter specified that they had never had a sidewalk emergency but didn't feel safe or comfortable walking on the sidewalks

The second commenter talked about how they were skateboarding on the sidewalk, hit a crack, and flew off their skateboard. They scraped their shoulders and stopped cruising around campus with their skateboard. They said it’s really hard to skate on VCU’s sidewalks because of these conditions.

The last comment specified that if people weren't on their phones, they would have no problems with the sidewalks.

These polls show that there seems to be a large amount of people who are bothered and get hurt because of the sidewalk conditions. There is also a very large amount of people who do not seem to care but they are still outnumbered by those who do. A large enough demand exists from VCU students to get these sidewalks repaired.

Plans for Sprint 2

For Sprint 2, our initial plan was to try and meet up with the Bishop of the Sacred Heart since he was the one in charge of the specific Cathedral Place sidewalk we've been observing. We planned on meeting with him on the 28th to see if he was okay with us repairing the sidewalks but sadly the church was closed for construction. The church is only open during mass. Our new plan is to have two people from the group try and attend mass. After it is over, they can try and interview the Bishop with a set of questions we have prepared.

Our other plan is to look for an alternative path just in case the Cathedral Place repairs don't work out. It's been very hard to get in contact with anyone from the church so we need to make sure we can fall back on another project if this one fails or takes too long.

I've been in contact with Paul Thrift, the Superintendent of Grounds at VCU. He told me he would try and get me in contact with someone from the Cathedral. If sidewalk repairs prove to be too difficult for us to try and accomplish during this project, we're thinking of instead focusing on less direct actions to try and keep pedestrians safe from the sidewalks. We asked Paul if there are any problems that the VCU Facility Management or anybody that is in charge of sidewalks at VCU needs help with. We could instead design posters to warn people of damaged sidewalks or raise awareness in any way that could benefit the VCU Faculty Management's sidewalk problems. My next goal with this plan is to set up a meeting with Paul to try and explain my plan.

Reflections

This first Sprint was the first time I've done a real-world project like this. I feel like we were a little too ambitious with our goals because of this. Having the Cathedral Place sidewalks repaired by the end of this semester is a process that takes way longer than any of us anticipated. It takes weeks for people to get back to us and each step of this process is way too slow for us to be finished by the end of the semester. I learned that we need a backup plan when it comes to projects like this. If we put all of our eggs into one basket, we might not be able to have anything accomplished by the end of the semester at this pace. This is why for the rest of the project, we will be focusing on a smaller scale goal instead.

I also learned that while it is good for everybody to have their own goals during a project, we still need to have collaboration so that our research all connects together. I feel that we have all gathered a great amount of research and that everybody in the group put in a large amount of work. While our individual research was good, I feel like we didn't do too much collaborative research so that we could all be on the same page and try and get to the same goal. For our next sprints, we will be doing more group research such as interviewing the Bishop or discussing our plans with Paul Thrift.

Student discovers 3D printable ink that 'everyone was looking for,' says physics professor

Finding a 3D printable ink that conducts electricity, yet is strong, flexible and stretchable, has been a goal of materials scientists around the world since 3D printing began, says Daeha Joung, Ph.D., an assistant professor in the Department of Physics at Virginia Commonwealth University's College of Humanities and Sciences.

So last year, when Andy Shar came into his lab eager to look for the solution, Joung was apprehensive but gave Shar a chance. And he is grateful he did.

"I was trying to find that ink myself," Joung said. "But somehow, Andy discovered the recipe."

The discovery has opened up new opportunities for Shar, now a sophomore majoring in biology in the College of Humanities and Sciences and minoring in religious studies in the School of World Studies. He has been working with Joung and his research team through the VCU Undergraduate Research Opportunities Program.

    Throughout the past few weeks, my team has mostly brainstormed possible routes we could take in order to eventually solve our problem: the lack of online food ordering at VCU. Since our problem involves changing something within the university, I’ve come to realize how ambitious this endeavor really is. This is only emphasized by our absolute lack of funding and prior connection to the higher-ups at VCU. However, we’ve planned the ways in which we’ll be focusing our research in order to make this idea seem like a profitable solution to modernize student dining and attract prospective students to VCU. So far, we’ve written questions for surveys and are collecting contact information of those in charge of meal plans and dining. In addition, our group has drafted the emails we plan to send to those contacts. Personally, I set up our entire demo presentation and have worked on iterations for the flyers we’ll use to get our surveys out there. 

    The first thing I want to do next is print out as many flyers as possible and hang them in places where we’d receive the most valuable responses. For example, freshman dorm buildings, the commons, library, lamp posts around campus, and various social media platforms. Particularly, VCU student facebook groups, VCU meme Instagram and Twitter accounts. I’m hoping to receive a lot of data from these surveys that we can then pass on to administrators at VCU. If we can show them what students want and what would attract more potential students, we'll start getting some headway into making our solution of online ordering at this university a reality.  

    In all honesty, this is not my first group project over zoom, but there’s been more struggle to spark successful collaboration in the past few weeks. I think our demo presentation could have been better if my group mates had contributed information to the slide presentation that I’d created for us. However, I can feel that we’re all putting a lot more effort in this week and everyone’s starting to get serious about moving forward with the project. This makes me hopeful for what we'll be able to accomplish. Overall, I’ve learned this project is about thinking outside of the modes I normally would. Furthermore, I discovered the importance of working with others to attain as many ideas as possible, and that no idea is a bad one. Moving forward, I plan on making adjustments to how I view the project. Although it’s ambitious, I shouldn’t believe what we’re attempting is impossible. If we can spark something within the people who have control at VCU to consider making this change, then that will stand as a huge success for my group mates and I.

Research Blog #1

My team and I have been working really well together, collaborating to find solutions to the pollution issue primarily around Belle Isle. During our first sprint, the team recapped on the progress we had made in researching this issue and the factors that contribute to it. Prior to the presentation, I made a group chat with my group mates in order to get easy contact with them, and discussed the roles within the presentation. Since this was my idea, I took on the role of describing the problem statement, and how it was refined after conducting the exercises. The original problem statement was lengthy, and did not accommodate as many different types of people as I would have liked. It was originally, how can we find ways to prevent people from disrespecting the environment and polluting the places we love to go to in Richmond? After working with the team, we narrowed the statement down to, large amounts of litter exist in Richmond river parks making them less accessible, safe, and enjoyable. After looking at the statement, I tried to decide what “litter” meant to me to try to categorize the types of trash that is found, and what types of groups of people that may be leaving this litter around. After making the customer map, using the adjectives of less accessible, safe, and enjoyable appealed to members in the inner circles such as, VCU Students, families, hikers, tourists, and the wildlife. Broadening to the outside circle, these adjectives appealed to many groups also like, associations and organization organizing events and volunteer opportunities to clean up these areas we are searching. Lastly, within the sprint we also all included research goals in order to give each member more direction on finding a solution. My goals included finding if there are limited trash cans in Belle Isle which may be contributing to the pollution issue. Also, learning and reaching out to organizations like the James River Association or Friends of the James River to see what efforts they have in place for combating this issue, and how we can further help that. As designers, I think we could make a difference on how people view and contribute to cleaning up Belle Isle.

My plan now looking forward is to continue researching into organizations around the James River that are helping with the pollution issue. People working within these groups are very knowledgeable of the contributing factors to this issue, why, and how we might be able to help. I sent an email to the James River Association in hopes to plan for a zoom interview to find some helpful information on how to solve this issue. I also went out to Belle Isle and walked to count all the trashcans they had available for people to dispose their trash. Along the whole walk alongside the rocks, there was a total of four trashcans. I think the area would benefit if there were more closer to where people sit and hang out. I began doing research on ways other groups have worked to help with pollution through art and design, and I think making visually pleasing signs, and trashcans would be a cool project. I would like to find and contact the organization that puts in the trashcans, and maybe get more there. Lastly, after discussing with local organizations or groups, I would like to utilize social media platforms like Facebook and instagram in order to promote incentives to want to help. I think along with helping keep the environment here, there is an awesome opportunity for a social incentive, and to meet other people working for a cause during this pandemic. Also, organizations with experience in getting people involved could be an important asset, and help my team to get people together and help out. I hope to make a lot of progress before the next sprint demo, and making these ideas come to life.

From this most recent sprint, I learned a lot about collaborating with people and working within a group setting. With Covid, many of us do not have the same opportunities to studio spaces to freely discuss and collaborate to find solutions. After working with three other people, and receiving feedback from the seniors, I found how powerful discussing and planning is to the end result. Skills like communication, mapping out the people affected by the issue, and prototyping are essential skills for the field I aspire to be in. I also learned how quickly two weeks goes by. I think my team worked really well in getting together an informative presentation, and would love to continue throughout this. As the weeks go on, I would like to be more on top of my goals in order to find solid solutions to this issue, or to minimize it.
