Challenges in Autonomous Vehicle Testing and Validation

A study, prepared by Strategy Analytics, predicts autonomous vehicles will create a massive economic opportunity that will scale from $800 billion in 2035 (the base year of the study) to $7 trillion by 2050. An estimated 585,000 lives could be saved due to autonomous vehicles between 2035 and 2045, the study predicts.​

While science fiction movies of the 20th century predicted that we’d have flying cars by now, it appears that there are a different set of overarching themes in the auto industry currently on the cusp of becoming a widespread reality. Electric power and the discussion around emissions, has arguably received the most media attention, however other trends such as vehicle sharing, and vehicles being connected to the internet and each other are also becoming prominent. A yearly updating model, where both software and hardware (particularly in fleets), will also become relevant to reflect rapid changes in technology. The final trend is perhaps one with the most technological challenges, and the greatest implication for changing how humans interact with cars (and transport in general): autonomous vehicles.​

An autonomous vehicle (also called a driver-less or self-driving vehicle) is one that senses its environment and operates without any human involvement. Companies such as Waymo, Uber, Tesla, and a myriad of others have been testing solutions for many years, however the task of testing and validating driverless vehicle technology comes with an array of challenges. Coupled with the fact that lives are at stake (both for passengers and pedestrians), there is little room for error. So what are the challenges facing autonomous vehicle testing and validation?​

Let’s start with the issue of gathering enough data, which needs to be collected both from vehicle sensors and from external sources, which is then used to train AI models. While real-world testing offers valuable feedback, there is the difficulty of scaling, where it is physically infeasible to run the millions of miles of tests required to gather enough data. Additionally, there is a need for test commonality, whereby identical tests are run with different types of vehicles. So how does such a large number of tests get carried out in an appropriate time frame? The answer lies in parallelized computer simulations, where, in the case of Waymo, they can achieve around 20 million miles a day in their Carcraft simulation platform (the equivalent of 100 years of driving on public roads). Waymo Driver, the company’s autonomous vehicle software suite, has reportedly accumulated over 15 billion simulated autonomous miles as of April 2020.​

The AI that drives a vehicle needs to also take into account various nuances during the vehicle’s operation, including the comfort of its passengers, which can sometimes be an overlooked factor during the testing process, which is why Waymo takes into account what it calls “Comfort Metrics”. Jonathan Karmel, Product Lead, Simulation & Automation at Waymo explained to VentureBeat that “Some of the key components are things like acceleration and deceleration, and we want to receive that information into simulation to predict what we think a rider or driver reaction would have been in the real world. There’s a machine learning model to predict what those reactions are in (Carcraft).”​

While comfort is important, safety is essential. Autonomous vehicles sometimes struggle during adverse weather conditions, and when approaching unusual objects on the road ahead. In 2016 a Tesla operating in self-driving mode crashed into an overturned white truck trailer on the highway, and another Tesla in 2018 slammed into a parked fire truck. In both situations, the car’s sensors failed to ‘see’ the objects ahead. This notion of ‘seeing’ the road and approaching objects becomes even harder during bad weather. An autonomous vehicle uses multiple systems to drive itself, including GPS, traditional cameras, radar and LIDAR (a technology that bounces lasers off the surrounding environment). The LIDAR system can lose accuracy when operating through raindrops and snowflakes, and the car’s cameras can be blocked by fog or heavy snow. Potential solutions to these problems include creating overlapping, redundant systems on the car itself (in case one is inhibited), along with cars communicating with each other, and even embedding sensors in the pavement to feed data to the surrounding vehicles.(Read More…)

Quality Assurance Services: Ensuring Excellence in Every Aspect

In today's highly competitive business landscape, ensuring the quality of products and services has become paramount. Quality assurance services play a crucial role in this pursuit, serving as the backbone for businesses striving to meet and exceed customer expectations. This article explores the significance of QA services, their key components, and the benefits they bring to businesses.

Key Components of Quality Assurance Services:

Testing and Validation: QA services encompass a comprehensive testing process to identify and rectify any defects or inconsistencies in a product or service. This includes functional testing, performance testing, security testing, and more. Through rigorous testing, QA services ensure that the end product meets the specified requirements and operates seamlessly.

Process Improvement: QA services focus on optimizing and refining business processes to enhance efficiency and effectiveness. This involves evaluating existing workflows, identifying bottlenecks, and implementing improvements. Continuous process enhancement is integral to maintaining a high level of quality across all aspects of a business.

Compliance and Standards: QA services ensure that products and processes adhere to industry-specific standards and regulations. This is particularly crucial in sectors such as healthcare, finance, and manufacturing, where compliance with standards is mandatory. QA services help businesses navigate complex regulatory landscapes and avoid legal implications.

Risk Management: Identifying and mitigating risks is a fundamental aspect of QA services. By conducting risk assessments, QA professionals can anticipate potential challenges and develop strategies to minimize their impact. This proactive approach enhances the overall resilience of a business.

Customer Satisfaction: Ultimately, the goal of QA services is to deliver products and services that satisfy customer expectations. By consistently ensuring quality, businesses can build trust with their customer base, leading to increased loyalty and positive brand perception.

Benefits of Quality Assurance Services:

Enhanced Productivity: QA services contribute to increased productivity by streamlining processes and minimizing errors. This efficiency boost translates into faster product development cycles and more timely service delivery.

Cost Savings: Detecting and addressing defects early in the development process is more cost-effective than fixing issues post-implementation. QA services help businesses identify potential problems before they escalate, reducing the overall cost of quality.

Improved Reputation: A commitment to quality through QA services enhances a company's reputation in the market. Positive customer experiences lead to word-of-mouth recommendations, attracting new customers and fostering long-term relationships.

Market Competitiveness: In highly competitive industries, maintaining high-quality standards is a differentiator. QA services give businesses a competitive edge by ensuring that their products and services consistently meet or exceed industry benchmarks.

Regulatory Compliance: For industries with stringent regulatory requirements, QA services provide the necessary assurance that products and processes comply with applicable standards. This is essential for avoiding legal issues and maintaining the trust of stakeholders.

In conclusion, quality assurance services are indispensable for businesses striving to thrive in today's competitive market. From ensuring compliance with standards to enhancing customer satisfaction, QA services contribute significantly to the overall success and sustainability of a business.

the only reason i'm in academia is for those perfectly incandescent moments when you've been staring at the same problem for 3 hours and then you finally, finally connect the dots (all on your own!) and you are instantly suffused with that shivery golden kind of pleasure because you did it! you figured it out. and maybe life is worth something because look at the beauty you're creating

[privateolives]

This is probably because I grew up watching 24/7 animal planet, but what finally made the allo/aplatonic thing click for me were the nature's of big cats.

Lions are powerful, regal creatures who are uniquely adapted to pack life. They need these connections to live a healthy life; A lonely lion is a miserable creature indeed.

Jaguars are solitary, beautiful creatures who live happily solitary. They prowl their lush world with self-sufficient majesty. A jaguar is not lonely without a pack. In fact, forcing jaguars to share space with others they do not enjoy is just as damaging as forcing a lion to live alone.

A lion may choose to head out on it's own for the most part, but in the end must return to the pack to thrive. A jaguar can choose to trust and enjoy the company of others, but they never feel the need to form a pack.

Is a jaguar selfish for this? A psychopath, a narcissist or any other such horrid assumptions? Is it a less moral creature than a lion, who seeks others like it to thrive?

Is a lion pathetic, or needy, or selfish for wanting community? For requiring contact with others like they require water? For their inherent need to string complicated webs of relationships that may seem silly or dramatic to others?

Of course not. These are ridiculous questions to even ask.

They are simply lions and jaguars.

In fact, is a jaguar that chooses to spend time with you not as magical as a lion's love? For a creature that needs no bond to thrive to still enjoy your presence enough to share it a time? Is a lion who can prowl the night alone not impressive in its strength and resilience? Is it not awe-inspiring in its ability to conquer a life it was never wired for and reign still?

Are they not both beautiful and awe-inspiring in their own ways, without being wrong?

Alloplatonics. Aplatonics. Are we not both special and beautiful in both our bonds and self-confident happiness equal, in each our ways? Is there not unique beauty in lifelong bonded packs and magical encounters that need no perpetuity to carry life forward?

Are we not but lions and jaguars? Neither wrong, neither selfish, but just different and beautiful creatures in each our ways?

That's how I've come to see it, anyway.

It's kinda shocking to me how few people seem to know how prevalent the 'my great grandmother was cherokee' myth is and how it's almost never actually true, especially when it comes with things like 'never signed up' or 'fell off the trail' or 'courthouse burned down destorying the documentation' etc etc.

People just don't even seem to know the history like.. when the Trail happened. My great great great grandfather was 2 years old during Removal in 1838, so peoples 'my great grandmother hid in the mountains!' is so clearly wrong. And we have rolls. From before and after removal, rolls done by cherokee nation and others by the government, rolls that were not stored in one random flammable courthouse. It's not difficult to find the actual evidence of ancestry.

And just.. there are lots of ways those family stories get started. It was a practice during the confederacy to claim cherokee ancestry to show one's family had 'deep roots in the south' that they were there before the cherokee were removed. Many people pretended to be cherokee and applied for the Guion-Miller payout just to try to steal money meant for cherokees - 2/3rds of the applicants were denied for having 0 proof of actual cherokee ancestry. [We even see lawyers advertising signing up for the Miller roll just to try to get free money.] And the myth even started in some families in the cherokee land lotteries, where the land stolen from us was raffled off, including the house and everything that was left behind when the cherokees were removed. We have seen people whose families just take these things stolen from the cherokee family and adopt them into their own family story, saying that they were cherokee themselves.

If you had some family story about being cherokee and you wanna have proof one way or the other, check out this Facebook group run by expert cherokee genealogists that do research for free. Just please read the rules fully and respect the researchers. They run thousands of people's ancestries a year and their average is only around 0.7% of lines they run actually end up having true cherokee ancestry.

BAHRAIN TESTING : Day 1 | George and Shov

[allwehearisradiosilence]

Hey just letting you self diagnosed autistic people know as a medically diagnosed person.

All those approved tests online made by doctors on self evaluating yourself for autism were used in my ACTUAL medical testing as well. They put the RAADS and Cat Q on me, they gave me “strongly agree-strongly disagree” questions. (Most of) Those tests are just as valid and just as accurate as a medical diagnosis that not everyone has the privilege and access to. You are valid don’t let anyone tell you those tests are “online propaganda for attention seekers” (my mother told me this)

tbh the two biggest fears i have about making the totk rant video (that i really do want to make) is 1. not actually making it bc i want to do alot of things and start them and cant get them done (yippie mental health) 2. it somehow getting seen enough i will be targeted by mass harrassment campaigns (which almost cost me my life once before ... and while i have grown i also think my support network is worse then back then)

i keep thinking about it and really wanting to do it and its important to be present and open about you and your values especially in this current climate- but i am, unfortunately, very afraid, some of it may be le anxiety but i also know what unhinged people can do to you if they believe you deserve it, whether that is actual bigots or angry gamer bros

[kittycouch]

The whole tikkatok situation is two steps below surprising but i will say the timeframe is something i couldn't have possibly imagined

You know what, I'm gonna share my potentially controversial yet firmly held opinion re: wrestling gimmicks

If your fans would struggle to agree on what your my little pony version's cutie mark would be and your MLP self wouldn't be immediately identifiable to someone who knows who you are, you need to refine your gimmick/character more

[vaguely-concerned]

I don't know what I love more, the fact that as rook you can make a statement in NO uncertain terms that you are NOT responsible one way or the other for the theological implications of the shit you're discovering in the 'regrets of the dread wolf' memories. not my jurisdiction. quite simply none of my business. not my chantry circus not my chantry monkeys. irrelevant to the matter at hand here we'll kill that god if we get to him he can get in line. or if the best thing about it is seeing the lone little 'lucanis approves' that pops up right after choosing it. corvid with a knife about to commit deicide keeping it real and sensibly, pragmatically, wilfully agnostic with me here in this magical lighthouse today

Went to a new library a few days back, i didn't know i could be that productive in a day .

P.S. my exams are in 2 weeks and i haven't even started studying 😭

⁠✯

my first post! I'm new to tumblr, I don't really know how it really works but i would like to try and start posting updates (ꈍ��ᴗ⁠ꈍ⁠)

[inthecarpets]

i hope Arknights Endfield will explore the lot of Mc's morality and that it'll be actually well written.

Arknights' the Doctor? A doctor and a commander. A war criminal, responsible for many deaths.

Endfield's Endministrator? Responsible for terraforming an entire planet? The implications of cloning technology being used for workforce inworld (if they stick with the cloning bit)? So many controversies there can be out there!

I've always been told I was smarter, better, more mature, and a good student. I was praised for being good and having the best scores. It just came so easily to me. I came to school, retained information, took tests, and completed the work. Now things are definitely harder. I'm no longer in regular classes, I'm in Honors. I don't know how to study. I've never been taught, and I never figured it out. Help.
