Cycling for research

As the ALIVE Charity Foundation gets ready for the next edition of the RE/MAX ALIVE Cycling Challenge for Cancer, Chairperson Nicky Camilleri tells us why, year after year, they continue donating funds towards cancer research.
Words by Iggy Fenech for RIDT.

Every year for the past four years, dozens of cyclists have committed themselves to training for 16 weeks, cycling over 1,000km in just one, and raising a minimum of €2,400 which is donated to cancer research. These cyclists are leaving behind a legacy.\

Why write?

By Prof Victor Grech

All academics are constantly encouraged to share their research with the world through journals. Furthering knowledge is the aim, providing colleagues far and wide with a building block on which to potentially further their own work. But are these noble motivations what really drive researchers to publish? According to a study by Bryan Coles (1993), the short answer is no.

It has been shown that authors in the sciences publish primarily to disseminate their own work (54%). Other reasons are the furthering of career prospects (20%), improving funding opportunities (13%), ego (9%), and patent protection (4%).

Clearly, there are huge personal motivations to publish, and with good reason. Globalisation has seen job competition rocket. Today, finding a job opening is hard enough, let alone climbing the career ladder. The term ‘publish or perish’ takes on a more threatening and terrifying overtone as this is now literal and no longer a metaphor.

Careers depend on publishing.I research is conducted without being written up as a paper and accepted in a reputable journal, then it is almost as if it has simply not been done at all. It has not been given official public recognition. Not only this, but even if one has a worthwhile research project to investigate and write up, there are many intervening steps that must be negotiated before a paper can be completed; from drafting a proposal for ethics and data protection, to opting co-authors, all the way to dealing with rejections, editors, and resubmissions, the road to publication is a rocky one.

Understandably, the process can be daunting for many. Thankfully, there are people and courses specifically tailored to help researchers with this. How to Write a Scientific Paper (WASP) is one of them: this is a three-day intensive course being held in London at the Royal College of Paediatrics and Child Health, with formal lectures and interactive sessions that will help researchers not only start their journey to publishing, but also see it through.

The organisers are also tentatively planning to hold another of these courses in Malta in 2017.

Robot see, robot maps

by Rachael N. Darmanin

The term ‘robot’ tends to conjure up images of  well-known metal characters like C-3P0, R2-D2, and WALL-E. The robotics research boom has in the end enabled the introduction of real robots into our homes, workspaces, and recreational places. The pop culture icons we loved have now been replaced with the likes of robot vacuums such as the Roomba and home-automated systems for smoke detectors, or WIFI-enabled thermostats, such as the Nest. Nonetheless, building a fully autonomous mobile robot is still a momentous task. In order to purposefully travel around its environment, a mobile robot has to answer the questions ‘where am I?’, ‘where should I go next?’ and ‘how am I going to get there?’

Like humans, mobile robots must have some awareness of their surroundings in order to carry out tasks autonomously. A map comes in handy for humans. A robot could build the map itself while exploring an unknown environment—this is a process called Simultaneous Localisation and Mapping (SLAM). For the robot to decide which location to explore next, however, an exploration strategy would need to be devised, and the path planner would guide the robot to navigate to the next location, which increases the map’s size.

Rachael Darmanin (supervised by Dr Ing. Marvin Bugeja), used a software framework called Robot Operating System (ROS) to develop a robot system that can explore and map an unknown environment on its own. Darmanin used a differential-drive-wheeled mobile robot, dubbed PowerBot, equipped with a laser scanner (LIDAR) and wheel encoders. The algorithms responsible for localising the robot analyse the sensors’ data and construct the map. In her experiments, Darmanin implemented two different exploration strategies, the Nearest Frontier and the Next Best View, on the same system to map the Control Systems Engineering Laboratory. Each experiment ran for approximately two minutes until the robot finished its exploration and produced a map of its surroundings. This was then compared to a map of the environment to evaluate the robot’s mapping accuracy. The Next Best View approach generated the most accurate maps.

Mobile robots with autonomous exploration and mapping capabilities have massive relevance to society. They can aid hazardous exploration, like nuclear disasters, or access uncharted archaeological sites. They could also help in search and rescue operations where they would be used to navigate in disaster-stricken environments. For her doctorate, Darmanin is now looking into how multiple robots can work together to survey a large area—with a few other solutions in between.


This research was carried out as part of a Master of Science in Engineering, Faculty of Engineering, University of Malta. It was funded by the Master it! Scholarship Scheme (Malta).

Leaving a legacy

A legacy gift is a planned future donation to a charity or trust which is given through a will or other designation. It allows individuals to express personal values by integrating charitable, family, and financial goals. Planned gifts drawn up in wills can be made in cash, or by donating assets such as stocks, real estate, and art pieces. The possibilities are endless.Continue reading

Testing MEMS

mems04How do you test the sensors in smartphones, smartwatches, and up-and-coming medical devices? With a Femtotools FT-RS1002 Microrobotic System of course! In 2016 the Department of Microelectronics and Nanoelectronics (Faculty of ICT, UoM) set up a slew of devices to be able to to probe, prod and poke devices up to a resolution of 1 nm (thinner  than the diameter of a human hair).

Quick Specs

Number of axes: 3

Maximum velocity: 5 mm/s

Minimum motion increment: 1 nm

Actuation principle: Piezoelectric scanning/stepping

Sensor probe tip area: 50 µm x 50 µm

FT-S100000 sensor force range: ±100000 µN

FT-S100000 sensor resolution at 10Hz: ±5 µN

Operating temperature: 5°C to 100°C

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.

Radio Telescope

Malta now has a radio telescope. This is a great step forward for the University of Malta as it helps speed up research.

The Department of Physics, Faculty of Science and the Institute of Space Sciences & Astronomy (ISSA; both at the University of Malta) have just acquired a 5.3m dual-reflector parabolic dish, as part of a European Regional Development Fund (ERDF) project to extend postgraduate research lab facilities. The radio telescope will now allow students and researchers to study celestial objects such as the sun or the centre of the galaxy through the radio waves they emit.

Quick Specs
Dish diameter: 5.3m

Feed horns: L-Band and K-band

Gain: 44 dBi @ 4GHz

Observing modes: Continuum and line observation

Total weight (including pedestal): 1900 kg

Surface accuracy: 0.5mm

PC-based automated control unit

toolkit03

toolkit02When pointed to a radio-loud celestial object (an object which emits large amounts of radio waves, such as the sun), the telescope will receive radio waves from these sources and convert them to voltage readings in the feed. The converted signal is then transmitted to a digitiser that converts these signals into bits and bytes.

The digitised signals are then processed and broken down into the different frequency counterparts (similar to what a car radio does with the radio waves it receives from its antenna), which allows for continuum observation of the skies above. The telescope provides a test-bed for several research initiatives being undertaken at ISSA.

Some of its specialisations include improving the hardware and software processing back-ends for radio telescopes. The on-site telescope can speed up this sort of research immensely. ISSA is part of the largest radio telescope project in the world: the SKA (Square Kilometre Array).

From Immigrants to Theology

Over 1.82 million migrants entered the EU in 2015 and this has triggered much dialogue across member states. In May 2015, the Archbishop of Malta, H.G. Mons Charles J. Scicluna, after the Vatican announcement of the Year of Mercy, reached out to the academic community to reflect on the immigrant phenomenon. This call set in motion The Mercy Project, which aims to create a set of reflections and recommendations around immigration.

The project has four stages. It first reflected on the issues of mercy and immigration within the Maltese context. During this stage, staff members from various University of Malta (UoM) faculties explored the local situation, reflecting on the terminology used, prevailing concepts and current practices. This was followed by a second stage. Academics held meetings to discuss various viewpoints and realities around migration. Those involved included members from the Faculties of Theology, Arts, Social Wellbeing, Laws, Education, and Health. At the third stage, a symposium on ‘Mercy and the Immigrant’ was held on 6 June 2016. The symposium brought together interested parties and agency representatives to reflect on the issue. This provided a platform for a dialogue between theologians and society. Rev. Dr René Micallef S.J. (Gregorian University in Rome) spoke about the mercy, justice, and policies needed to be considered by Malta and the rest of the EU.

The final forth step is underway. A publication of the project’s position papers is being prepared. This will make available to various sectors of the public some of the philosophical, social, legal, educational, and theological ideas which surfaced during the project’s dialogues and consultations. It will provide concrete recommendations for the University of Malta, State, and the Church. 


Dr Pauline Dimech and Rev. Dr Stefan Attard are the project co-ordinators.

Special Feature – The Maltese Genome

DNA is what life is made of. Found in every cell of the human body, it has sent criminals to jail and been the focus of controversial court cases. Dr Jean Buttigieg discusses these legal and ethical issues. DNA has also transformed the meaning of being human, with traits from disease to intelligence all linked to it. DNA is changing the world.
