The Mac, the iPod and the iPhone are just a few of the innovations that have changed the face of consumer technology. Sleek, functional design and a founding myth of three friends in a garage are foundations of a brand that many student Engineers dream of working for. For Bristol University student Jamie Surjeant, this dream became a reality in the summer of 2018, when he interned for Apple at their California HQ.
Professor Ben Hicks visited Jamie whilst he was on placement and said the opportunity, environment and support are exceptional. The fact that Jamie has been embedded in a design team and has been working directly on Apple products from day one is testament not only to his ability and his undergraduate training at Bristol but also the value and importance of interns to Apple. Apple interns are also given considerable support to assist them in relocating for the duration of their internship and are part of a large community of interns who support each other.
Jamie has now been offered a long-term position with Apple, who were so impressed by Jamie’s work during his internship that they are now collaborating with the Industrial Liaison Office to offer Bristol Engineering students internships in California this summer. Interns will be working on Apple TV Product Design. Interested students need to apply by midnight on the 29th October.
Phishing is coming to an inbox near you… And the attacks are getting more sophisticated by the day. Rob Larson from the University of Bristol’s Cyber Security group talks to us about the latest developments and how you can protect yourself online
Last year, 76% of organisations experienced phishing attacks, with nearly half noticing an increase from the previous year*. According to the FBI, American businesses lost $12.5 billion through corporate email attacks. Closer to home, the NHS ransomware attack of 2017 affected dozens of authorities; staff resorted to using pen and paper, and operations were cancelled, with potentially life-threatening results.
Not only are these attacks on the rise, but scammers are turning to ever-more sophisticated methods, exploiting moments in our everyday lives when we’re at our busiest and most vulnerable.
This is an area which interests Rob Larson, whose PhD focuses on online social engineering attacks. He questions the long-standing idea that individuals are the weakest link in the security chain, instead seeing them as an asset and the first line of defence. He believes that a strong organisational defence is multi-layered, with systems fortified through technology and staff trained to understand the psychology of phishing attacks.
Rob explains the prevalence of phishing attacks: “When it comes to defences, organisations have traditionally put up a perimeter, to keep the bad guys out, and locked down the systems inside it, in case they get in. So it’s often easier to just target the users of the systems, sitting behind the defences.”
We asked Rob about the wide-ranging aspects of phishing – and for some advice on what to look out for online.
“I’ve always had an interest in the psychology of social engineering, such as phishing scams, and why something so simple remains so effective.
“As a computer scientist, I wanted to understand how they’re performed, why they’re successful and what defences are available. I really wanted to bring our understanding of social engineering up-to-date and address this belief that the people who fall victim are at fault.”
On the evolving face of phishing…
“Phishing can be a very low-cost, low-overhead attack as opposed to using exploitative code to break through a hole in the system, or other costly techniques. Traditionally it was deployed willy-nilly with hundreds to thousands of emails being sent, as spam. Now, we’re seeing not only an increase in the number of attacks, but also an increase in their sophistication. Instead of casting a wide net with a mass generic email, they’re targeting a small number of people with content which is more relevant to the recipient.
“Take a university, for example, the email might talk about systems such as ‘Blackboard’ which students within the university actually use. It might reference specific personal details to seem more legitimate, such as their student ID number or course name. Links in the email might then take users through to a website which is tailored to look like the university’s web portal login, asking the target to input their username and password.
“It’s common to see emails putting pressure on the target to elicit an emotional response. Fear of loss is a common one, like replicating a university email and warning the student that they’ll be withdrawn from their course if they don’t respond quickly. If the student clicks on the link they’re redirected to a fake university system and once they’ve logged in the system steals their credentials. The email will thank them for confirming attendance so they’ve no reason to suspect anything.
“These emails have a greater degree of sophistication and subtlety… They’re similar to earlier, more generic phishing scams, but are well-targeted and done in a way that users are less likely to report them, or even notice they’ve fallen victim to anything.”
“Part of my research is trying to understand the spectrum of spear phishing and how sophisticated the attacks get. Spear phishing is a bit of a different animal to the more generic, widely distributed spam-like email; it might be a bit more specific, mentioning you by name. It could come from a contact which looks familiar or appropriate, such as a friend or a colleague, or may include some personal information. It’s quite common to see scammers deploying persuasive techniques in these emails, that leverage authority. For example, they might impersonate your boss and importantly, it might be requesting urgent action.
“Scammers often want a quick reaction – they want you to just respond on auto-pilot. You’re taking a heuristic route and going off your gut, rather than taking time to think it through. It’s something we do naturally, that we need to do to work effectively, and they take advantage of that.”
On ‘crime as a service’…
“Spear phishing used to be so labour-intensive. It was the preserve of people who had the time, money or interest; state actors; organised criminals after big money; or cyber criminals with a persistent interest in a target;
“But now you can buy this kind of service on the Dark Web, for as little as $25. Criminals can go there and say: ‘I want to impersonate a bank, I would like that bank’s website and login page cloned.’ They can pick-up a similar domain and a security certificate. It’s gotten to the point that for very little cost, they can even hire a call centre, and direct users there to steal information by a different route, or add a degree of authenticity.
“It’s a perfect storm. Stolen personal information can be bought and sold online. You can buy tools and services to generate websites, and software packages to generate phishing emails that already include these psychological ploys within the templates.”
On whaling (or ‘CEO phishing’)…
“Whaling, or Business Enterprise Compromise is also increasing dramatically. Think of whaling as ‘phishing’ for a really big fish. For example, criminals target someone in finance and the CEO of the company. They might compromise a device on the company’s network, and send an email appearing to come from the CEO instructing someone in finance to make a money transfer.
“In the past five years, according to the FBI, this kind of fraud has cost US business $12.5 billion. That’s not a small figure by any kind of reckoning. If we’re talking about subtlety or lightness of touch, whaling is right at the top end of the spear-phishing spectrum. The focus is on one person and it will be very targeted and very specific.”
On social-media phishing…
“Another good example of phishing is on Facebook. Someone might visit a club, and check in on Facebook – the scammers message them that they’ve been tagged in a photo at that particular club on that particular night. They click on it because it’s somewhere they actually were, maybe they’re worried that it’s a terrible photo that they don’t remember. If the hackers manage to compromise the target’s social media account they can then use that to launch targeted attacks on their contacts.
“Recruiter scams are also common. Because many legitimate companies recruit primarily through LinkedIn, it’s definitely a good place to be if you’re job hunting. People put loads of information on there about their university and educational history, crucially, the kind of job roles they’ve held in the past and are currently looking for. A prevalent attack comes from fake recruiters or head-hunters. With all the information people are sharing about themselves it’s very easy for a scammer to tailor a convincing job offer email.
“It’s easy to say be careful about what you share online, but it’s always a toss-up between the benefit you’re getting from using an online service and the risk.”
On what to look out for in phishing emails…
“Despite this greater sophistication in scams, a lot of the advice given about spotting phishing still stands up. So watch out for any of any of the following when you receive an email:
It’s generic or impersonal: they don’t greet you by name or mention your account number, instead using an ambiguous greeting such as “Dear user, student, or customer”.
The message looks odd: spelling or grammar errors are common in less sophisticated attacks. Company branding or logos may be incorrect or appear poorly formatted.
The email address of the sender looks wrong: for example, a message might claim to come from ‘email@example.com’ but the email shows as ‘firstname.lastname@example.org’. However, it is possible to impersonate or ‘spoof’ addresses, so you shouldn’t rely on this alone.
It’s asking for sensitive or personal information: such as your password, PIN etc.
It’s trying to rush you with an urgent deadline to respond.
It has a suspicious link or attachment: similarly to email addresses, links that do not match the web address of the company or service the email claims to represent.
On protecting yourself online…
“As I’ve mentioned, a common goal of these scams is to steal your username and password. Don’t forget to use different passwords for different services and use strong passwords too. It doesn’t have to be the letters, numbers and special characters thing that a lot of sites promote – you could use pass-phrases like six random words, tied together with hyphens. But make sure the words aren’t related to you and are as random as possible. Personally, my preference is to use a Password Manager which generates strong passwords and stores them securely. I’d also recommend services with two-factor authentication, that’s when you login and have a second code sent to you. So, even if your username and password is stolen they still need another piece of information.
“There’s been a lot of advice about phishing and social engineering detection. Some of it is really questionable. For example, ‘don’t click on things’ – that’s like saying you should never leave your house if you don’t want to get mugged!
“My advice is to treat any approach like somebody coming to your door to sell you something. If you don’t have the time to check their credentials, don’t play into their time frame. If you’ve got 50 emails and one pings a red flag to you, put it into a folder, crawl through the other emails, and come back to this one when you’ve got time to look at it properly. Don’t reply to it, don’t click on the link, don’t open the attachment. If the email claims to come from an external organisation, such as your bank or University, call the bank directly via information on their official website rather than links or numbers in the message. If it’s from a friend or someone internal to your organisation, drop them a quick call to check.
“At the end of the day, it’s important for individuals and organisations to understand that even with extensive training and a detailed understanding of these scams people still fall for them, because they leverage vulnerabilities present in all of us and happen whilst we’re distracted by other things.”
On collective responsibility…
“People will still mistakes, such as choosing weak passwords, so organisations need to support them with technology and policy where possible, such as taking measures to prevent weak passwords being used or limiting the speed at which attackers can try to guess a password. An awful lot of the systems and countermeasures out there still fail to support the user adequately, meaning these relatively simple attacks remain a big problem.
“So for my PhD, I wanted to find out what’s really going on. I wanted to give something back to help people devise better training, build better defences and create software to lessen the burden on users and to ultimately make people’s jobs easier in the fight against cybercrime.”
The University of Bristol’s Cyber Security Group is part of the Academic Centre of Excellence in Cyber Security Research (ACE-CSR) at Bristol. The group’s research focuses on three over-arching but interlinked strands: security of cyber-physical infrastructures, software security and human behaviours.
It’s Green Britain Week this week. While debate rages between environmental campaigners and those wandering the corridors of power, engineers are ever pragmatic and practical. Our researchers are working on a range of technological advances that will reduce the carbon in our atmosphere.
Here’s nine of our projects:
Wind power: Harnessing wind power will be a key component of a greener energy mix. In partnership with Offshore Renewable Energy, the Wind Blade Research Hub is pushing the boundaries of current technology to produce a 13MW turbine. They are working on blades that will be 100m long, requiring new designs, materials and manufacturing processes. The world-leading expertise of the Bristol Composites Institute (ACCIS) is crucial in delivering this and other sustainable structures.
Offshore wind and tidal lagoons:In another initiative to tap into the UK’s potential for offshore wind and tidal energy, a proposed tidal lagoon in Swansea Bay could provide electricity for more than 155,000 homes. It will take a solution that is affordable and scaleable to turn this idea into a reality. Researchers from Bristol and Plymouth Universities are part of a project to design and develop a prototype.
Solar Cells:Solar energy is getting ever-more affordable. A £2 million grant from the EPSRC has funded work to develop new low-cost photo-voltaic materials. Researchers from the Bristol Electrochemistry Group’s PV Team are looking to replace elements such as gallium, indium, cadmium and tellurium which are rare, expensive to extract and toxic.
Electric Vehicles: The move away from petrol/diesel and towards low carbon hybrid/fully electric vehicles depends on the availability of compact, highly efficient engines. The Electrical Energy Management Group are innovating and testing solutions. Their industrial collaboration on high performance electro-mechanical drives is important for the traction, steering and road handling of the cars of the future.
Energy Storage:If the sun is shining and the wind is blowing, how can we store all that free energy? This question is being addressed by researchers from the Universities of Bristol and Surrey as part of self-funded company Superdielectrics Ltd. They have discovered new hydrophilic materials, like those used in contact lenses, that could rival the storage capacity of traditional batteries and charge much faster. Rolls-Royce recently signed a collaboration agreement with Superdielectrics, highlighting the keenness of industry to find new solutions.
Microgrids:Ditching fossil fuels and halting deforestation can’t happen unless there’s a sustainable energy alternative. It’s estimated that 1.2bn people across the world don’t have access to electricity. By working with NGOs, local authorities and residents in rural areas, researchers from the Electrical Energy Management Group are designing a micro-grid system, intended for remote communities. It could generate enough power for 250 homes, using wind, solar and micro-hydro energy. A scaleable modular design means extra units can be added as and when.
Water management:Climate change is having an impact on our water cycle with flood patterns already changing. The way we manage water resources will be increasingly key to mitigate natural disasters and provide clean drinking water to a growing population. The Water and Environmental Engineering group brings together engineers and scientists, taking a multi-disciplinary approach to the complex issues raised through modelling, measuring and prediction.
Efficient Aircraft:Aviation is a major contributor to global CO2 emissions, burning more fossil fuels per passenger than any other form of transport. The Advanced Simulation and Modelling of Virtual Systems (ASiMoV) partnership aims to produce a jet engine simulation so accurate that designs can be signed off by the civil aviation authorities pre-production. It is hoped that by modelling the physical effects of thermo-mechanics, electromagnetics and computational fluid dynamics, more cost effective and energy-efficient engines will get off the ground.
LettUs Grow was founded in 2015 by three Bristol University Students – Ben Crowther and Charlie Guy (Engineering Design) and Jack Farmer (Biology).
As a company they wanted to tackle some of the biggest problems facing the planet, by reducing the waste and carbon footprint of fresh produce. Their solution was to design and develop aeroponic irrigation and control technology for indoor farms. On World Food Day, they share their thoughts:-
Global warming and greenhouse gas emissions are two of the defining problems of our generation. Agriculture is a big piece of the puzzle, producing a third of global emissions. But the problem of global food security is much more than just emissions. A stable food supply is a fundamental human need and there is a severe lack of innovative solutions to help feed the next generation.
A common misconception about plants is that they only “breathe” through their leaves, but part of the oxygen and CO2 they use is also absorbed through their roots.
We knew things needed to change, so we devoted ourselves to finding food-focused solutions. By combining our backgrounds in engineering and biology we’ve found innovative ways to help indoor farmers scale up their operations to compete with traditional agriculture. Our novel technology builds on the successes of hydroponics and addresses many of the issues which have been holding back indoor farming.
A common misconception about plants is that they only “breathe” through their leaves, but part of the oxygen and CO2 they use is also absorbed through their roots. By suspending our plants’ roots in the nutrient dense mist rather than in water, we’ve overcome some of the problems faced by hydroponics. Because they’re not submerged, plants can respire optimally during their whole life cycle. Using this system, called aeroponics, we’ve seen up to a 70% increase in crop yields over hydroponics.
The UK was ravaged by storms and snow from February to March, scorched by months of temperatures exceeding 30°C.
As is often the way, aeroponic growing’s biggest strength can also be its greatest downfall. Most systems produce their mist by pushing nutrient-rich water through strips of nozzles. The small holes quickly become clogged with falling plant debris and a buildup of salts and nutrients – much like how limescale forms inside a kettle. We’ve developed a system without any nozzles, so there is nothing to clog and break. Alongside our patent-pending hardware, we’ve also developed an integrated farm management software system, called Ostara®, which reduces labour requirements, optimises conditions for plant growth and makes farmers’ lives easier.
The incredible weather of 2018 has shown the need for this sort of technology. The UK was ravaged by storms and snow from February to March, scorched by months of temperatures exceeding 30°C during the summer and more snows are predicted before the end of the year. These extreme weather conditions put an enormous strain on farmers. They’re faced with the choice of swallowing their losses or increasing their prices – something tricky to do when at the mercy of supermarkets!
If you’re keen to see one of our aeroponic grow beds in action and learn how we can help feed the next generation, come visit us at the People’s Tech on Saturday 20th October in the Engine Shed. We’ll be there along with another agri-tech startup, the Small Robot Company, who’re replacing bulky inefficient tractors with small robots. Tickets start from as little as £3 and can be bought from here: www.eventbrite.co.uk/e/peoples-tech-october-tickets-49245025196.
Starting university can be daunting at the best of times, but even more so when you’re studying overseas and leaving your home country for the first time.
That’s what Indian student Samia Mohinta faced when starting her MSc in Advanced Computing last month. Samia has thrown herself into life in Bristol and has some advice and insight for others in a similar position…
Are you having cold feet – terrified to leave your home country? Or have you taken the big leap, but missing home? Keep reading! This post lists all that I found useful while coming to the UK and after two weeks of being here.
This is my first time anywhere outside India. I am an avid traveller, but stepping out of India, to go to a place for a year without family and friends, did freak me out. So, trust me, I can understand how you all are feeling. Don’t worry, you are not alone.
Here are a few tips to help organise yourself and shake off the blues before and after you travel to the UK:
Prepare beforehand: If you are planning to study at the University of Bristol, get an idea about the city before you arrive. Bristol is hilly, so start working on improving stamina, because you’ll need a lot of that when you climb up to reach your lectures. There are quite a few blogs on the city of Bristol and reading one of those will give you sufficient information of what the city is like. Currently, for me, it’s fantastic.
Review your goals: Think and write your aspirations on a page. Judge your potential. The Indian model of imparting education is very different from here. Unlike in India, you won’t be spoon-fed with information and details all the time. You need to be self-motivated and alert to grab the opportunities that come your way.
Understand the course you are going to take: Go through your course modules and check if you understand what it’s about. This is very important. I have seen a lot of my friends dropping out of courses that they chose without self-judgement of potential. Follow your interests and think about your existing experience and skill set.
Reach out for help: If you are travelling alone from India to UK, reach out to people if you face any problem. Don’t panic. Speak to your co-travellers, even if you don’t know them and ask for advice. You shall definitely find someone travelling to the same or a nearby place. Team up! I myself had a four-hour delayed flight, which led to a lot of problems after landing in Heathrow. I reached out to the University representatives, who were present at the airport, bus stops and train stations, and got my issues sorted.
Only pack for one week: Don’t fill your bag with unnecessary stuff. Bring dry food to last a week. Pack some cooked food, just to soothe your cravings. Bring hoodies, warm jackets, gloves, mufflers and sweat shirts. Also pack a few cottons and summer dresses. If you can, pack a pressure cooker or a rice cooker – extremely useful to prepare a quick meal. Carry some cloth hangers and air-tight tiffin boxes as well.
Indian food: Do not carry a lot of Indian spices because you can get everything in the supermarkets. But I shall ask you to pack a small amount of flour or rice for making chapattis or rice, so that you do not need to rush to a supermarket immediately after you arrive. There are a lot of Indian restaurants all around the city, pop in to satisfy your occasional cravings. Take a bus to Easton and find loads of Indian stuff.
When in Britain, do as the British do: Try and get a brief idea about the British culture. You should know how to greet people when you meet them. In India, we usually don’t shake hands, but here it is a common courtesy. Be polite and friendly.
Make new friends: I know it sounds weird. You cannot just be friends with someone after a tiny chit chat. However, meet a lot of people. I am not suggesting you to jump into parties, but during uni hours speak to your classmates and get to know each other. You can join a few societies or clubs (there are nearly 200 clubs and societies in UoB) and make a few friends. Get out of your comfort zone and shake a leg at a dance taster session.
Explore Bristol, reduce boredom: Bored with sitting at home? Grab a backpack and put your travel shoes on. Time to explore Bristol! Bristol boasts of beautiful parks, hot-air balloons (I am personally fascinated with these), Ferry rides at the Harbourside, the Clifton Suspension Bridge (loved the view from it), Museums and some fantastic graffiti decorating the walls of the entire city. Get a student’s one-day bus pass for £3 and explore the Bristol inner zone. You can also buy an outer zone pass that lets you access Bath and Bristol completely for a day.
Take your modules seriously: Go to the lectures. Don’t get unnerved if you find the first few a little difficult. Read the materials and ask for help from your professors. There are dedicated teams for mental health in the University, who can help you cope with the study pressure. A lot of Indians study at UoB as well, reach out to them via the Indian Society and share your worries.
Life is all about taking risks. Sign yourself up for an adventure every day and reap the satisfaction it brings. This new world in Bristol is a lot different from yours back in India. It is way more organised. It is also extremely welcoming. Be confident. You shall shine!
Thank you for being with me till the end.
PS : I shall come back with some other fun stuff about my adventures in Bristol. Stay tuned!
There are many options at Bristol if you need any support settling into University life or just need to chat to somebody. Find out where to get help here.
Dave Cliff, Professor of Computer Science, talks about his experience with a break down in his mental health. How catastrophic thinking, panic attacks and the stigma around mental health made his life miserable and how he came through the other side.
Talking about your mental health (good, bad and everything in between) is something we really encourage and we’re proud that our staff are leading by example. If you’re a student and need to talk to someone about your mental health or get some support you can talk to the teams in your school office, or find more resources on the University of Bristol website. If you ever need a chat you can contact the Samaritans 24/7 no matter who you are.
“People said I was brave”
Dave talks about people’s reactions to the video and the bravery of asking for help
I once made a video, or should I say: a video was once made of me. It was a talking-head interview, about the time I had a breakdown. Severe anxiety and depression; suicidal thoughts. It’s seven minutes long, and I speak maybe a thousand words.
I did it because I was asked to do so by a colleague, an old friend, who was putting together material for a new non-credit bearing elective course that would be made available to all students at The University of Bristol, where I work. I didn’t give it much thought, didn’t know what questions I would be asked and didn’t rehearse any of the answers. We shot it in one take, maybe 25 or 30 minutes in total, and then the video production folk went away and skilfully edited it down to a more manageable length. Once the final edit was released to our students, and to the rest of the world on YouTube, I started getting feedback, comments — people saying nice things about it — and in those comments something caught me by surprise. There was this one word that got used a lot when people commented on what I’d done, a word that I didn’t expect at all. People said that I was brave.
I’ve thought quite hard about this and, given this opportunity to write about it now, almost 18 months since we shot the footage and more than five years since I got sick, I’d like to explain why I don’t think I was brave at all. Or, at least, why I don’t want to be thought of as brave for making a video.
Should I first introduce myself? I’m a Professor of Computer Science at The University of Bristol, a role I’ve been in for the past 11 years. Prior to that I’d held professorial posts at Southampton and at MIT, plus I’d spent seven years working in frontline industrial artificial intelligence R&D for Hewlett-Packard and for Deutsche Bank. But what I’m writing here isn’t about my CV. Let’s get back to this bravery thing.
If someone was cycling too fast, had an accident, broke a limb, received medical care, took time off work to get well, and came back fixed, that’d be pretty routine. What if that person then made a talking-head video about what happened, how they’d been riding too fast for too long and how after the accident they don’t ride quite so fast now, quite so recklessly, now they know how painful the end-result can be? Would we call that person brave? I think not. When I made this video I didn’t for a moment think that I was being brave, because it shouldn’t be an act of bravery to talk about what is, after all, an experience that very many people go through and in which for many people, like me, the story ends well. I was just doing what I wish many more people would do, talking openly and honestly about mental health. I got sick, dangerously so. I sought help and got good care, for which I remain very very very thankful indeed. And I got better. And then I told people what happened. How does me telling that story mean that I’m brave?
I’m acutely aware that it doesn’t work out this way for everyone: some people suffer from chronic mental health issues that go on for a very long time, lifetimes even; some people don’t find, or ask for, the right help in time; their stories may not end nearly so as well as mine. In these senses, I was lucky.
As far as I’m concerned, me telling my story wasn’t a brave thing to do at all. It was an act of thanks, a little celebration of my recovery. Like getting back on the bike and going for a ride and enjoying the wind in your face and laughing out loud that you’re once again able to do something you love; that you’re fixed, the bad times are behind you, that you’re well.
Looking back over the whole sequence of events, if I had to choose one thing I did that I do think of as brave, it was the moment when I was first sat facing my doctor, took a deep breath, and spoke honestly about what was going on inside my head. Before I could get a word out I was in tears and could barely talk. But I knew I had run out of road, that I’d lost control and that I couldn’t deal with the situation alone. For me that was an extraordinarily difficult step to take, one that I very nearly didn’t. I am so glad that I did, and I guess I’m writing these words in the hope that maybe they’ll encourage someone else to take that first step, to reach out and ask for help. In my opinion, that’s the brave bit: the bit when you ask for help. No video required.
Writing this has made me think quite hard, and I realise now that when I spoke to my doctor that was the first time I’d said those words out loud. I was talking as much to myself as to the medic: it was my first admission, not just to my doctor but to me, that I was in a desperately bad way; the first time I said that I needed help. I wasn’t just telling my doctor I was sick, I was telling me too. For me, that was the really difficult part. If ever I was brave, that was the brave bit.
I’m very glad I took that step but it was not at all easy. If my video encourages others to take the same step when they’re in a bad place, to be brave enough to admit they need help and to seek that help, then I think it will have been useful. I hope that it is.
The world’s largest student engineering design competition is back. We spoke to Engineering student Harry White about the Formula Student project and being a part of the Bristol Electric Racing team
Formula Student is a long-running international competition where the best engineering students across the world design, manufacture and race open-wheeled single seater formula styled vehicles. The vehicles produced by some of the top teams are truly astounding feats of engineering, with some cars able to accelerate from 0-60 MPH in under 1.5 seconds! The big finale is the head-to-head race at Silverstone, where the teams battle it out to find the overall winner.
Chief Engineer, Harry White, explains the uniqueness of this project: “This competition is one of the best opportunities available to university students to experience a complex, real-life engineering problem that requires analytical thinking, design and team work.”
“It allows students to develop important skills that may be less focused on in a classical engineering degree, such as business, marketing and cost analysis.” He continues “We’ll be working hard towards developing our business and marketing case, with the goal of ranking amongst the top teams next year.”
This year’s team are currently building their first car to compete at the 2019 competition. Harry updates us on their progress: “We have most of a rolling chassis, with only a few modifications still required to produce a product that fundamentally works. The next steps this year will be to develop the powertrain, which is no small task, and to continue developing the rolling chassis until the car can drive under its own power. From there the next task will be an extensive testing and commissioning stage. There’s a significant difference between a car that can move and a car that can race.”
One of the great benefits of the project is for the students to work equally as part of team, with all members having the opportunity to contribute significantly to the design. As Harry points out: “There’s a lot of design involved with creating a car from scratch, and this means that younger members of the team can contribute in a way that would be almost impossible in more established teams.”
Importantly, there’s the social aspect of the project: “Working as part of a dedicated team, all focused on achieving the same goal, leads to a tight-knit group of friends, between different years and courses; a social dynamic that is difficult to find elsewhere.”
As Harry sums up: “Formula student is an amazing opportunity that gives real engineering experience and is as rewarding as it is demanding; at Bristol Electric Racing there is the opportunity for anyone who is motivated enough to do great things.”
The Impossible Garden is a set of new experimental sculptures, by artist Luke Jerram, inspired by visual phenomena. The exhibition is a collaboration with Bristol Vision Institute and aims to enhance our understanding of vision. All summer visitors have been exploring the garden and discovering engaging art exhibits, designed to stimulate debate about how visual impairments can affect our perception of the world around us. We gathered some of the best Instagram shots of the exhibits so far.
Think you can do better? The University of Bristol Botanic Garden is a riot of colour as the season change, so grab your camera. The Impossible Garden is open to the public until Sunday 25 November 2018. Open from 10 am until 4.30 pm, 7-days-a-week, including bank holidays. For those with visual impairments, we have audio and braille copies of the brochure available.
Engineering Design student Joe McFarlane has just returned from his Year in Industry in Uganda and Kenya. As well as having a significant impact on the company’s processes and submitting a range of successful tenders, he spent six months project managing a landing bay project. Joe was the youngest and most senior person on site, managing a team of 50 people. The company have already asked him back when he graduates.
Here’s Joe’s experience:
I spent my Year in Industry working for East African Piling in Uganda and Kenya. The company specialises in a variety of piling solutions for private and public infrastructure markets across East Africa.
At first I was mainly working on design and costing proposals for upcoming projects. Services offered include rotary bored piling, continuous flight auger piling, sheet piling, soil nailing, soil anchors and pile load and integrity testing. Through the year I contributed towards 11 bids, 4 of which the company won.
After this stint working on tenders, I moved on to become the Project Manager of a new marine slipway on the coast of Kenya. The slipway extends 74m into the Indian Ocean and was constructed using a sheet pile cofferdam. At the deepest end of the cofferdam, the maximum retained depth of water was 6 m. The completed structure is 105 m long and 6.5 m wide.
We built the cofferdam using a 75 m long barge as a platform. A crane-slung vibrating hammer was used to drive the sheet piles into the seabed to the required depth. Once the cofferdam had been built, the water was pumped out using two 4-inch submersible pumps to create a dry working space. The existing seabed was excavated to a 10% gradient and back-filled with hard-core material. After this, precast concrete slabs, haunches and underlying geotextile material were placed into position from the end of the slipway up to the junction with the existing road. The final step of construction was to flood the cofferdam and cut the sheet piles at a gradient to be flush with the slipway’s haunches.
Despite having to overcome significant challenges over the course of the project, it was a major achievement to produce a quality product which meets all client requirements, within the specified budget and two weeks ahead of schedule.
I thoroughly enjoyed my Year in Industry, having learned an incredible amount about the design, management and implementation of engineering projects. I would recommend it to anyone studying Engineering. With the placement proving to be such a success, I look forward to working with the company again in the future.
