I have been directly involved in ICT for over 30 years. The last 10 years have been all dedicated to ICT in health.

I have visited hospitals and health centres in the United States, Canada, the United Kingdom, Ireland and Italy. During the several health conferences I have attended, I met with people from practically every corner of the world. Their common denominator: no health system is sustainable unless ICT is perceived as an enabler to assist health providers deliver an improved and more efficient care service that governments can afford.”Malta shares this concern. The added pressure is its ageing population.

Q:How can ICT truly reduce the financial pressures on our Health Service and make it sustainable?

A:Malta needs to develop a culture where citizens realise their responsibility to monitor their own health and maintain their own online electronic medical record. This can be done through daily, weekly or monthly monitoring of vital signs such as blood pressure, weight and others. Studies prove that people using eMonitoring services take better care of their own health.

I urge the Ministry of Health to run a simple pilot project in Malta. It could be run amongst the diabetic community. The pilot project would include 1,000 people. 500 of them will use the standard glucose-monitoring device while the other 500 will use a personal, electronic glucose-monitoring device. Within three to six months the results will show the superiority of eMonitoring devices for patient care. These existing health tools can enable people to live healthier lives and stay away from our overburdened hospital. The key is to control a condition without depending on medicines.

Q:Length of stay in hospitals and outpatient visits can be reduced through eMonitoring devices. How?

A:How many patients remain in hospital after medical intervention to have their vital signs monitored? Using these devices patients can be discharged from Mater Dei sooner by being given an eMonitoring kit to monitor themselves from home. The data would be sent electronically to Mater Dei for doctors or clinicians to analyse. These devices could reduce the patient length of stay and make more beds available at Mater Dei translating into reduced costs and waiting lists. They could alleviate the number of outpatient visits that would reduce pressure on the infrastructure and workforce providing more time to increase care quality. Such devices provide an opportunity for every Maltese citizen to have an online electronic medical record that would be always available to clinicians and general practitioners.

My vision for the Maltese health service is one of empowerment. The patient will be enabled to take better care of him or herself and become more accountable, disciplined, and committed to self-healthcare in the same way someone is committed to their job or hobby.

Well-being for all through E-health

E-health uses electronic processes and communications to enhance healthcare. The aim is to improve patient care, reduce costs, and empower patients to work towards maintaining their own well-being.

To work e-health needs a lot of data about patients. This health data is also crucial to discovering new drugs and improving patient care. Using specialised devices and telemedicine, a wide range of conditions can be monitored at home. Smartphones can process the information and transmit it to healthcare professionals and/or patients. Using e-health, conditions can be monitored continuously providing real-time monitoring of the condition and its treatment. 

For the full potential of e-health to be realised electronic health records need to be linked to other information, like images and text. This combined knowledge then needs to be distributed through a cloud service, so that a patient or doctor can see it immediately. Genetic profile and socio-economic factors can also be included to provide improved diagnoses and health predictions. In addition, approaches such as data mining offer exciting research opportunities. Data mining can help identify more effective treatments, improve drug safety, reduce risk, and better public health systems. E-health can improve how diseases develop and disabilities are spread throughout different populations.

Assistive technology can be provided through an intelligent healthcare device. These devices include a dispenser that might text you to remind you to take your pills — especially useful for patients with memory problems. If the patient does not take their medication after multiple reminders, the system could automatically alert a family member or carer. This could prove a lifesaver for patients with depression or dementia. Through relatively simple technology, patients can take care of themselves at home, reducing the burden on hospitals.

At the University of Ulster we have been researching e-health solutions for decades. It ranges from cloud computer systems for ‘big’ healthcare data to home-sensor based reminder systems for Alzheimer’s patients. We have also worked with designers to embed sensors into clothing designed to help older people become more active outdoors. Our focus has been to developed new algorithms (computer programmes that do a specific task) to analyse data collected by a system of devices. What we learn from these algorithms can be used to adapt the environment to take better care of the patient. Such feedback is essential to make the technology seamlessly integrate with a patient’s needs and preferences. Feedback could either be through an audio prompt or transmit an alert to a carer indicating that assistance is required. The research opportunities are endless.

In Malta, the University of Malta is well placed to leverage research opportunities for local solutions. Key components are already in place in several faculties, where the focus on Communications and Intelligent Computer Systems is particularly relevant to Malta, with a number of ongoing e-health research projects.

E-health provides business opportunities for the private sector. It can take academic research and use it to develop new technologies, deploy it, or manage it. For example in Northern Ireland there has been a huge interest in developing these business opportunities by creating awareness among investors. This investment can bring improved health and well-being, while supporting economic development. Such developments could be relevant to Malta which is similar to Northern Ireland in having a geographically peripheral location within Europe, an integrated healthcare system, and a technically skilled workforce. Due to its objective of establishing a regional hub for a knowledge-based and ICT-enabled economy, SmartCity Malta could be well placed to bring together the research expertise of the University of Malta and businesses. Together they could advance Malta’s healthcare for everyone.

In ancient times games played an integral role in society. Whilst in today’s hyperlinked world, games have evolved into complex, sophisticated mechanisms that enthral millions. Now, however, games are dismissed as trivial, and of no real value. But is this really the case? Cassi Camilleri meets the research team gamED from the University of Malta to find out.

Making 3D multi-view TV a reality

Research in 3DTV has been active for the past decades. Its popularity is growing rapidly driven by market forces and new technologies that are bringing down costs enabling a more widespread distribution. Normal 3D video uses only one camera to generate two video streams for each eye. Multi-view video allows the viewer to choose which angle they want to watch (pictured).

Multi-view video needs to process huge amounts of data since it needs to transmit many different camera angles of the same scene. If the 3D videos are being streamed in real time, the processing power needs grow even further. To reduce computer processing the multi-view plus depth concept was introduced. Using this idea not all the alternative videos are used. Instead a few are selected and the angles in between are filled using sophisticated computer algorithms. The challenge with this approach is to generate high quality videos at different angles whilst keeping the amount of data transmitted as low as possible.

To attempt to overcome these problems, Maverick Hili (supervised by Dr Ing. Reuben Farrugia) analysed the current state-of-the-art video coding standard called H.264. The idea is to compress the amount of data which is transmitted without losing video quality. To achieve a better compression, the depth information in a video was represented with a few parameters. The receiver then has to use these parameters to reconstruct the original depth information. Hili managed to improve compression using this technique, an important step to be able to stream live 3D video into our homes.

This research was performed as part of Masters in Telecommunications within the Faculty of ICT at the University of Malta. It was partially funded by the Strategic Educational Pathways Scholarship (Malta). This Scholarship is part-financed by the European Union — European Social Fund (ESF) under Operational Programme II — Cohesion Policy 2007–2013, “Empowering People for More Jobs and a Better Quality Of Life”.

The Bright Side of Life

Alu_AngeloDalli

My passion in life is succeeding at building competitive and highly competent teams of people who are driven by a common vision towards success, in other words, setting up successful companies. I am a serial entrepreneur with an almost fanatic obsession for using IT and sound business sense to create disruptive solutions in various industries, including the transportation, entertainment, gaming and big data analysis fields.

My interest in IT started when developing small applications as a teenager in secondary school, selling my first program within a few months for a very tiny amount of money. I spent it the following weekend. Soon after, I took Computer Science seriously and ended up representing Malta in various international events. In 1995, when I was 16 years old, I won Malta’s first-ever bronze medal at the International Olympiad in Informatics (IOI). Five years later, I graduated from the University of Malta with a Bachelor’s degree in IT and a Master’s degree in Computational Linguistics. Then, I moved to the UK, where I read for a Doctorate in Computer Science and Search Engine Technology from the University of Sheffield while working for various European Union research projects.

In the UK, I set up one of my first companies. A few years later it became Traffiko, an Intelligent Transport Systems solutions company with offices in the UK, Malta, and Australia. I also wrote proposals that were funded by the UK Joint Research Council and the UK Ministry of Defence Science and Technology Lab (DSTL). Additionally, I published and presented over 23 peer-reviewed papers and journal articles. Around 2005, I built a cluster of servers that copied all text on the Internet to test search engine technology.

In the past decade, I have been focusing on setting up successful IT companies in multiple countries, dealing with the challenges of managing operations in different time-zones and people with different cultures and training. My current businesses all largely employ Maltese IT professionals. They include gaming platforms, cloud-based data-mining and next generation people-sourcing platforms.

The importance of having a diverse skill set and an open mind is also something that leads to career excellence and personal satisfaction. I believe that Malta offers a good base of IT professionals who can achieve brilliant results within the right framework.

I am currently a member of the European Business Angel Network (EBAN). The network helps provide access to early stage finance to entrepreneurs with great ideas that need seed funding, mentoring and guidance.

A good foundation in technology, engineering, and science subjects gives the right analytical and logical analysis skills. They are useful in development and solving issues encountered by IT and technology entrepreneurs — from formulating a business plan to turning a start-up company into an IPO (a company that can be launched on the stock market) in a planned manner.

IT skills should always be coupled with a sense of appreciation for business needs. Entrepreneurs need a healthy dose of optimism and inquisitive curiosity tempered by a logical, practical approach. This philosophy has always been my vital skill set for success.

Wi-Fi Security Map for Malta

Wi-fi is ubiquitous. The technology can be an easy back door for hackers to access a computer through online tools that anyone can learn to use. The global cybercrime bill now tops €700bn and will keep rising. To find out the security of Maltese Wi-Fi networks Kurt Mahoney (supervised by Prof. Ing. Victor Buttigieg) mapped out around 70% of the island’s built-up areas.

Mahoney first carried out in-house testing on Wi-Fi security protocols. He then formulated security categories depending on ease and speed of access to a private network. For example, the WEP (Wired Equivalent Privacy) security standard could be cracked in less than one minute (irrelevant of password complexity). On the other hand, the WPA2 (Wi-Fi Protected Access II) security standard with AES (Advanced Encryption Standard) grade encryption and a twelve-character random alphanumeric password was virtually impossible to crack using brute force techniques.

Setting up a car with several Wi-Fi antennas, he then travelled a preplanned route through all the Maltese villages, apart from Mdina. Private security protocols were noted from automatic Wi-Fi transmissions, however he avoided conducting cracking or penetration testing. Mahoney then created a security map for the Maltese Islands from 64,317 observed private networks. Forty percent of private Wi-Fi networks in Malta were very vulnerable to hacking that increased to 90% if using more sophisticated attacks.

Wi-Fi security was poor all over the Island, with Western and South Eastern districts having marginally lower security. Malta needs a nationwide awareness campaign to increase the security levels of Wi-Fi networks. Top-notch security can be setup in a few minutes. All modern routers support military grade AES encryption standards, and together with a proper password policy one would render a Wi-Fi network almost invulnerable to direct attack.

This research was presented at the fourth Workshop in Information and Communication Technology (WICT). It was performed as part of a B.Sc. (Hons) in ICT at the Faculty of ICT and part sponsored by the Malta Communications Authority. It was shortlisted for the Chamber of Engineers’ Best ICT Student’s Project Award.

Better, cheaper smartphones

MICRo-electro-mechanical systems (MEMS) are about the width of a human hair. They can tell a smartphone which way is ‘up’, enable inkjet printers to eject ink precisely, and are even found in high definition displays. These chips have sensors that detect a physical quantity such as temperature or direction, which is then converted into an electrical signal. The signal can be passed on to a customised computer chip designed for a specific use, called an application-specific integrated circuit (ASIC). A MEMS device operating through an ASIC is called a microsystem, commonly found on handheld devices. Students at the University of Malta are currently researching ways to crucially improve these devices.

Over the past years, research into MEMS has developed sensors for temperature, pressure, inertial forces, chemical properties, magnetic fields, radiation, and more. These tiny microsensors outperformed their larger counterparts at a lower price. Recently, they were adapted for gas and liquid flow control, optical switches, and mirrors found in video projectors.

Locally, the Department of Microelectronics and Nanoelectronics is collaborating with STMicroelectronics, which is funding postgraduate studies in both MEMS and ASIC design. They are investigating accelerometers that, for example, enable a smartphone or a gaming console to know how the device is being held. The Department is using the latest manufacturing techniques to test its research innovations.

Accelerometers have two main functions: sensing direction using an MEMS chip, followed by processing the information using an ASIC. Both chips are placed on a single package. The research focuses on reducing power consumption and cost, which will enable smartphones to perform better at a lower price.

“Training in this field will hopefully entice industry to develop research and design teams focused on this rapidly expanding field,” says Dr Ivan Grech, senior lecturer at the Faculty of ICT. The development of microsystems is an attractive and exciting area of study, which provides new and innovative ways to use smart devices for everyday applications.

 

Research in this area was carried out by Ansel Briffa, Jean Marie Darmanin and Kristian Grixti, as part of their Master of Science in Microelectronics and Nanoelectronics at the Faculty of Information and Communication Technology. They were supervised by Dr Ing. Edward Gatt, Dr Ivan Grech, Dr Ing. Owen Casha and Prof. Ing. Joseph Micallef.
