DESIGN L-g침 L-

g침 is a thoughtful, innovative, and interactive exhibition. The reaction it provokes is from the very base of the

senses and is the first final year project exhibition from BFA in Digital Arts degree students organised by the Department of Digital Arts, Faculty of Media and Knowledge Sciences. The exhibitors chose an intriguing moniker: the most enigmatic and iconic rune in the Maltese alphabet (L-g침). Together they used it as a starting point and explored the thematic elements it connotes. The students tapped into six themes and developed twelve projects. Despite majoring in animation or graphic design, each artist worked with a subject they discovered and developed over several months. Creativity and variety are abundant, with projects ranging from audio-visual experiments and curatorial work to interactive documentaries and highly thematic visual material. The body of research and thought behind each project sheds recognition on conceptual and creative transformations currently occurring in the practice of art and design. They shift the boundaries of art, design, and media and how they can be used together.

of spinning particles at close to the speed of light, it smashes them together in the bid to better understand the fundamental makeup of matter and ultimately answer the age old question. A magnificent feat of engineering, the LHC goes where no other machine has gone before. The magnets it uses to guide the particles’ trajectory are cooled to temperatures below those found in space. On the other hand, the collisions are over 100,000 times hotter than the sun’s core. These collisions generate enough data per year to fill millions of hard drives. The cables needed to transfer that data could be wrapped everything.

arduous for Giubellino and the ALICE has grown over 26 years to now encompass over 1,500. With no legal structure holding them together, everyone continues to collaborate, all the while bringing in their own resources, trusting that they will be respected and valued. And they clearly are. Propelled by the keen curiosity that brought them together all the way back in 1989, they continue to venture into uncharted territory, changing the world as they go. ‘What we have achieved here is unique,’ says Giubellino, and we at THINK could not agree more.

Physicist Dr Giacinto De Cataldo (Head of the HMPID detector) got in touch with Gatt and Casha to work on two microelectronics projects for CERN. Their first project was the O2 Project—a series of upgrades for the ALICE experiment. One of upgrades focuses on improving the RingImaging Cherenkov detector (RICH), found in the HMPID detector, a device that identifies the type of electrically charged particles being emitted by the detector. The second project is the implementation of a Remotely Configurable L0 Trigger Fan-out Module for the ALICE Detector. It involves the clocking management of the ALICE detector with high precision. This research could also be used in consumer telecommunication systems, improving radio frequency circuits’ performance.

“My summer experience at CERN was remarkable. The sharing of knowledge among students and researchers was the highlight of the trip. During the openlab programme we attended lectures about security, machine learning, computer hardware, software optimisation and lots more, many of which are topics not covered at our home university. We also played a role in the ALICE experiment and I worked on my project alongside top notch computer scientists. Another positive aspect of the programme were the various trips to companies and universities in Switzerland. Being able to say that I have worked at CERN is something I will value throughout my career.”

PHYSICS CERN SUMMER STUDENT

ʻThe months spent at CERN for the summer student internship programme were not only an invaluable experience, but also an insight to future potential careers for my colleagues and I. Based within the HMPID detector of the ALICE experiment, we had a six-week lecture program focused on the fundamental properties of nature. The bulk of the work we were involved in centred on implementing programming languages to process raw data from collisions into useful knowledge. Geneva provided a change of pace for us that was conducive to both hard work and extra curricular activities. Travelling across borders, visiting main projects and control centres at CERN, while also socialising with students from all over the globe, made it an all-encompassing experience not easily matched.ʼ

So far, he has manipulated computer processes to create parallelism, allowing for processes that previously happened one after the other to occur simultaneously. He also used high-throughput interconnects, which, when coupled with parallelism, are expected to increase data collection tenfold.

Option two would kill 400 people. ‘In this case,’ comments Brockdorff, ‘most people would advise the minister to go for the first option; the more risky option.’ ‘Intelligent’ robots that live in the fantasy world of Asimov’s

Brockdorff wanted her work to improve people’s lives. Evidence-based policy making was her chance to make a difference

Knowing how people make decisions is an important area of research in the emerging fields of cognitive science and cognitive neuroscience. As Brockdorff explains, decision making is interesting as a matter of pure scientific interest; the quest for knowledge. More important to society, however, it is essential that governments and policymakers understand how people make decisions in order to do the greatest good. Her lab is particularly interested in studying decisions making to inform public policy. Her lab’s researchers investigate the way people

THE SOLUTION The DFRG is made up of podiatrists, engineers, surgeons and researchers from the Centre for Biomedical Cybernetics, the Department of Podiatry (University of Malta), Mater Dei Hospital and Staffordshire University. Their goal is quite simple at face value but invariably complex in practice: to detect diabetes and foot-related issues before obvious problems rear their ugly heads. The current gold standard in diabetes detection involves the analyses of blood pressure. A doctor compares the blood pressure in the ankle against the forearms, a measurement known as the ankle-brachial pressure index (ABPI). When the pressure is lower in the ankle, it means an artery is blocked in the lower limb. However, this method is not a completely accurate indicator and only provides information on the ankleâ&#x20AC;&#x2122;s blood supply; the rest of the foot is not considered. Additionally, when the toe brachial pressure is recorded, measurements are only taken from the big toe or the second toe, not all of them. The pressure index is also effectively useless when a patient is older or has chronic kidney disease because of calcification in the arteries that can skew results. All this highlights how unreliable the current gold standard in diabetes detection is. Diabetics are known for not having an equal blood flow throughout their foot. Imagine that blood supply has stopped in a diabeticâ&#x20AC;&#x2122;s small toe.

will be lost. This has led the DFRG researchers to investigate the potential of thermographic imaging, also known as Medical Infrared Imaging. This is a quick, non-contact technique that eliminates the risk of infection while providing important information about the blood supply to the feet. The research is currently in its second phase and already making significant headway. The first part of the project assessed thermographic images of healthy individuals. Foot and hand temperature patterns were analysed, followed by an evaluation of the thermal symmetry of the same limbs on opposite sides of the body. This study concluded that the hands and feet demonstrate a characteristic

Naqsam il-MUŻA is a branch project inspired by MUŻA. Currently in progress, participants in the Naqsam il-MUŻA project were selected from different communities around Malta and taken to see the art collection of the National Museum of Fine Arts. They will then exhibit their choice of artwork from the museum in their localities. It brings the museum to the people, rather than the other way round.

In Malta, the Sant’ Antnin sewage treatment plant produces recovered waste water supplied mostly for agriculture, and to a lesser extent, industry. The recovered water consumes 3.5 times less energy to produce. The demand for the regenerated water has been in decline (National Statistic Office, Malta, 2014) and there are also reports of low quality water from the plant. Malta recently invested in developing waste water recla iming technologies, with the intention to eliminate over extraction from aquifers and then regenerate them using reclaimed water. Cost effective reactors use advanced oxidation processes, which is the aim of Zammit’s project, are integral to these water reclaiming plants. Through the project, the scientists also aim to better understand antibiotic resistant spread from reclaimed water to crops which has health implications for consumers worldwide. The project has the potential to improve Malta’s water situation and the world’s health. Reducing antibiotic resistance will help control this burgeoning problem. Ian has just started the first year of a three-year grant and says, ‘I would love to do research for a living, be it academic or industrial’. Here’s hoping he does.
