Ships to Computers
In 1991, when the first DOS-based PCs started to become available, I graduated from the University of Malta after having read for a degree in Electrical Engineering. The Internet and mobile telephones still had not appeared.
There were no ICT courses at the UoM. Engineering courses were the closest I could come to entering this field. Teaching of computer science was therefore obviously limited, but at least we recieved a fair amount of computer architecture and networking theory. We also built our first processor boards, and wrote our first code in assembly language. The Dean was not thrilled when I approached him to announce that I wanted a ‘software only’ thesis, a first. But I got away with it, and built a software driver for a LAN card, a networking card, using a programming language called Modula 2.
When I graduated my computing future did not look bright. I was tied by a two-year contract with Malta Shipbuilding, to whom I was assigned during the student worker scheme. I had spent three summers working there managing a team of electrical technicians, which toughened me. After this experience, managing teams should have been relatively easy.
During my last months at University I decided that I wanted to enter the IT world. I started shopping around for a job while doing some teaching at a private school. I landed a job at the software company Megabyte as a systems engineer and decided to end my contract at Shipbuilding paying the required financial penalties. Financially not the best decision but best for my career.
After seven years at Megabyte , I moved on to become the CEO of the Internet company Maltanet. I spent 8 years running the company. In Malta, during this time the Internet market was growing exponentially. The pace of technology accelerated tremendously making it a very exciting time within a highly competitive environment. When GO was fully privatised we merged all the subsidiaries and I spent nearly 3 years as Chief Commercial Officer for the group. Managing the commercial portfolio of a quad play operator was an instructive and rewarding challenge.
Today I run my own firm called ICT solutions. In 2009 I set up a joint venture focused on two areas, ICT servicing and software development. It employs a team of over 20 people, mostly UoM graduates. They provide solutions to cater for the ever growing ICT requirements of the corporate world.
So what lessons have I learnt? Firstly, there is no ‘one size fits all’ solution and everyone needs to build on their strengths. Secondly, you need to put in long hours. If you do not work harder than your normal 9 to 5 employee, then you will remain a normal 9 to 5 employee. Thirdly, you need to keep abreast and understand technology cycles and where the market is going.
Be technically competent but appreciate business logic. Fourthly, and most importantly, relate to people and build relationships with your team and clients.
Hand pose replication using a robotic arm
Robotics is the future. Simple but true. Even today, they support us, make the products we need and help humans to get around. Without robots we would be worse off. Kirsty Aquilina (supervised by Dr Kenneth Scerri) developed a system where a robotic arm could be controlled just by using one’s hand.
The setup was fed images through a single camera. The camera was pointed towards a person’s hand that held a green square marker. The computer was programmed to detect the corners of the marker. These corners give enough information to figure out the hand’s posture in 3D. By using a Kalman Filter, hand movements are tracked and converted into the angles required by the robotic arm.
The robotic arm looks very different from a human one and has limited movement since it has only five degrees of freedom. Within these limitations, the robotic arm can replicate a person’s hand pose. The arm replicates a person’s movement immediately so that a person can easily make the robot move around quickly.Controlling robots from afar is essential when there is no prior knowledge of the environment. It allows humans to work safely in hazardous environments like bomb disposal, or when saving lives performing remote microsurgery. In the future, it could assist disabled people.

The making of Offshore Wind Energy
Malta has a problem. It relies heavily on fossil fuels such as oil to meet its energy needs. Whenever oil prices increase, either the people or the government take the brunt of the cost. The country also faces a strict deadline: by 2020 it needs to supply 10% of its energy needs from renewable sources such as wind, solar, or wave. To help reach this goal, a new project at the University of Malta is custom-designing offshore wind turbines.
Malta’s territorial waters are quite extensive but deep. The Hurd Bank area is the most suitable site at a depth of 50 to 70 metres. These depths are beyond the reach of current commercially available technology and the latest project in the windy, turbulent North Sea reaches 45 metres (The Beatrice
Project).
To construct a wind turbine for the Maltese region, Thomas Gauci (as part of a team consisting of University academics and industrial partners) is designing a structure specific to Malta. Seventy-metre deep waters will increase costs. On the other hand, the Mediterranean is relatively calm compared to the North Sea, so the support structure keeping the wind turbine in place can be lighter, which shaves off tons of raw materials and reduces the final price.
An offshore wind turbine needs to resist waves, corrosion, and storms. The design process of an offshore support structure is essential to keep it in place and starts with determining exactly where the turbines will be embedded and how they will be supported. After these questions are answered, the turbines’ exact specifications need to be determined, such as material, height, width, and what forces it can resist over a number of years. Speed of blade rotation also needs to be checked to make sure it does not cause discomfort to nearby humans and animals. Mr Gauci’s concept design meets all of these needs in compliance with international and EU standards. At this stage, the design needs to
be costed, right down to the installation and maintainance of the turbines.
If Malta builds these offshore wind turbines it would easily meet the 10% baseline set by the EU. Undeniably, such a large project will face numerous challenges, but perhaps Mr Gauci said it best: “not a day goes by when I don’t learn something new.”
