The team of computer scientists collaborated with global semiconductor chip maker ST Microelectronics to p roduce MEMS (Micro-Electro-Mechanical Systems). MEMS are the tiny sensors or devices often found in smartphones that allow them to act like a compass, know how fast a person is going, or detect sound. In Malta, the new equipment is being used to measure mechanical properties (for example shear testing and flexure testing) of tiny mirrors that can be used to turn phones into high-quality projectors (part of the Lab4MEMS2 project part-funded by the EU). This toolkit is incredibly versatile, forming part of a station that can have additional add-ons to widen its applications. Now the team wants to buy more sensitive microforce probes and microgrippers that will allo w the manipulation and assembly of microsystems. This toolkit’s micromechanical testing can be used in many research and industrial applications. This way, the horizon is open for studies into semiconductor technology, microsystem development, materials science, micromedicine, or biotechnology—placing Malta on the semiconductor map.

 

Upgrades, Updates & ALICE

Analysing Alice: Finding order in chaos

With every particle collision in the ALICE experiment, a terabyte of data per second is generated for analysis. But not all of it is essential information. David Reuben Grech speaks to Dr Gianluca Valentino and Dr Johann A. Briffa about their work in separating the wheat from the chaff and removing noise from two of ALICE’s 18 subdetectors.

Meet the research team

Prof. Ing. Edward Gatt & Dr Ing. Owen Casha – Faculty of ICT

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 Ring-Imaging 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. Finally, Gatt is researching how to improve chip designs used to detect physical phenomena from particle collisions with the aim of making them more intelligent and power-efficient.


Kevin Napoli – Computing CERN Openlab Student

 kevin-napoli“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.”


Julia Vella – Physics CERN Summer Student

julia-vellaʻThe 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


Josef Magri – M.Sc. Student

josef-magriThe HMPID takes snapshots of the faint patterns generated by the high-energy collisions, passing this information through the RICH electronics module which cleans and transforms it for analysis. Magri is working to optimise the electronic circuits and control boards to improve how data is handled. 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. Magri’s work will be combined with that of other researchers and integrated by 2020 in order to improve the detector’s accuracy, potentially revealing building blocks of matter that might have yet to be seen.


Clive Seguna – Ph.D. student

clive-segunaWorking in close collaboration with Magri, Seguna is developing novel electronic circuitry for the CPV and HMPID detectors, that will boost the speed at which collisions are read, going from 4 kHz to 50 kHz, the speed at which the beams interact: true real time. Seguna’s research will be taken on at CERN between 2020–2023.


Further down the rabbit hole

The European Organisation for Nuclear Research—CERN—is synonymous with the world’s brightest minds, cutting-edge research and groundbreaking discoveries. Lars Lorenz interviews Dr Kevin Vella (Faculty of ICT) about the University of Malta’s involvement at CERN and its game-changing tech contribution to the ALICE experiment.

Counting pennies for creativity

Crowdfunding has proven to be a revolutionary business-financing phenomenon. From an A to Z list of every indie game, record or publication imaginable, to rebuilding homes, rehoming puppies and sending people to the Olympics, crowdfunding platforms have shown they can be just the right kind of push to get hatchlings to fly the nest. Having a local crowdfunding platform gives entrepreneurs and communities in Malta a unique edge.

Crowdfunding is a place where local ideas, concepts and projects meet and can receive public support. But, in a world of large crowdfunding opportunities across the globe, what does Malta actually stand to gain by having a platform with a local focus?

Financing options on the Maltese Islands are notoriously limited. Over 70 per cent of small-to-medium enterprises (SMEs) resort to traditional lending services like bank loans and overdrafts. Getting a new business off the ground is a daunting task, and 30% of local entrepreneurs admit to finding difficulty in securing investments.

Enter Zaar, the donation and reward-based crowdfunding platform set up by the Malta Business Bureau and the University of Malta [UoM]. The idea initially was to help bridge gaps in the market when it comes to financing for start-ups, innovation, and research projects. A local crowdfunding platform helps local companies by bypassing the legal and bureaucratic obstacles that come with using international platforms. While projects targeting Maltese recipients benefit from local context and backing, backers need not be based in Malta at all. By giving local creators the space to attract funding in the most efficient way, Zaar aims not only to fuel dreams, but to fulfil them.

That being said, Zaar is not just about financing, and one of the company’s core values is about getting good ideas out in the open. In operation for seven months, the platform has managed to fund everything from album launches to charity events. Some of the most successful offspring to date include: a soon-to-be launched Pet Cabin at Mater Dei; eeMod—a modular and multi-functional platform for makers, engineers, and students; funding for the UoM student racing team to build a new formula style car; and a project to bring graphic novels to Malta’s Public Library. Without a little push from Zaar to get public interest going, none of these projects may have made it.

Local crowdfunding also opens up new avenues for researchers and their projects. Governmental and EU funds are becoming harder to come by, but Zaar ensures that every researcher who has ever been told that their field lacks the appeal for funds, at least has the opportunity to try. For the first time, people have the chance to fund studies that they want to see done, and the thought of that is genuinely exciting.

Crowdfunding is going to be a game changer for innovation, and Zaar has the first pin down on the local map.
