How do you cook the perfect steak?

Fillet is the best cut. Trust me. It’s worth the money.

Use molecular gastronomy to take advantage of decades of researching how meat changes with heat. Science indicates that the best cooking temperature is around 55˚C, and definitely not above 60˚C. At a high temperature, myofibrillar (hold 80% of water) and collagen (hold beef together) proteins shrink. Shrinking leads to water loss. In the water lies the flavour.

To cook the fillet use a technique called sous vide. It involves vacuum wrapping the beef and keeping it at 55˚C in a water bath for 24–72 hours. This breaks down the proteins without over heating. The beef becomes tender but retains flavour and juiciness.

Take the beef out. It will look unpalatable. Quickly fry it on high heat on both sides to brown it. The high heat triggers the reduction of proteins or the Maillard reaction. Enjoy with a glass of your favourite red.

Which tablet?

Tech Review

A few weeks ago a good friend of mine made the mistake to ask, ‘Which tablet should I buy?’ After two hours and a long rant, I think he regretted asking that question.

The reason? Until a few years ago buying a tablet was easy, few products really competed with the iPad. Now, however, the choice is much more difficult.

The tablet market is very varied with products ranging in price from a few hundred euro to €1000. So are the more expensive tablets always better?

The answer has to be a resounding ‘no’. And the choice is not limited to budget. You would also need to consider size, both physical and memory-wise, OS (Operating System), and manufacturer.

The right choice mostly depends on the intended use. As an e-book reader alternative, a light and portable 7 to 8 inch tablet seems ideal. Here Google’s Nexus 7 proves an excellent budget choice, with the iPad Mini a more expensive but stylish alternative.

Size does matter. If you intend to use your tablet to browse the internet or watch movies a 10 inch tablet is your best choice. Here the iPad Air still provides a powerful tablet with an excellent display in a lightweight package. Equally strong and stylish are the offering from other manufacturers such as the leather cladded Samsung Galaxy Note and the waterproof Sony Xperia Z2.

If you wish to replace your laptop with a tablet, now you can. Windows based tablets as the Microsoft Surface Pro 2 add a clever keyboard and a full Windows 8.1 experience to provide a real alternative to a laptop. Hybrids such as the Asus Transformer, a netbook with a detachable screen, and the Lenovo Yoga show that functionality does not need to be sacrificed when opting for a tablet.

I could go on, and on and on…

Students for Research

Education is a word we are constantly bombarded with. After sitting for hundreds of exams, having read thousands of notes, spent endless nights fighting with coffee machines and sticky notes, you probably know the hardships of our education system. However, education is much more than books and lectures.

Education is a way of life. It changes us and can bring out our potential. Our University is the place we all come to learn, work, and ultimately spend most our time. Be it students, staff members, academics, or researchers, it is of utmost importance for us all to be in line with why we are all here, to nurture education and develop our society’s future.

The University has been growing rapidly in the past decade. Construction is ongoing, labs are being renovated, and the number of postgraduate courses and doctorates has grown exponentially. Naturally, research has spiked up too, and the UoM is also spearheading a few world-class projects.

Why am I putting so much importance on research? The answer is simple. Without research Malta can never make a leap forward to improve our quality of life. The main aim of research is always that of identifying and exploring new knowledge that will ultimately make our world a better place.

Locally, researchers are not just donning white lab coats. Maltese researchers are diving deep into Mediterranean waters to explore native aquatic species, some are crawling face down in garigue environments to investigate local flora and fauna, while others are breaking new grounds to find the Maltese genetic components responsible for cancer and other deadly diseases.

Students perform research for their dissertations (see the student section of Think). This is when a student will first experience hands-on research. A university supported to conduct top research is necessary to give students more real-world research opportunities. Encouraging a research mentality within the early stages of the University experience is essential to foster a lifetime commitment towards our alma mater.

Unfortunately, the biggest obstacle in research is funding. This problem is worldwide. But whilst other countries have already made substantial efforts to fight this problem, locally we have just started to get the ball rolling to instill the much needed awareness and culture around research funding.

Investing in research is essential and we are seeing an initial good response from society. People are slowly starting to realise that through research we are not only creating a hope for future generations, but we are also aiding the education of our children and helping our country’s socio-economic well-being. In the past year we have managed to raise important funds for cancer and kidney research, and other important causes.

The University Research Trust’s latest initiative, in collaboration with the KSU, is a project whereby students can directly donate funds towards research within their faculties. Dubbed as the UoM Caution Money Scheme, this initiative lets final year students from the Faculties of Engineering, ICT and Sciences donate their laboratory caution money towards research projects and equipment in their faculties. Ten students, who decided to set an example for their peers to follow, launched this scheme during an annual KSU event, showing that everyone can contribute towards research at University.

We are now encouraging all final year students from these faculties to follow suit and also contribute towards research. Malcolm Zammit, one of the students who already donated the money appealed to his peers saying, ‘This small deposit we had left in our first year is negligible when compared to the amount that the University has invested in all of us. Today, I feel it my natural duty to give something small back to this place which has given me so much.’

The initiative has also encouraged other student organisations to donate. ELSA has just given the Research Trust some funds for University research. These initiatives are all helping towards fostering more awareness and funding so that together we can  continue leaving a tangible impact on our campus and society.

TxK

Game Review_Costantino

TxKTxK marks the return of seminal designer Jeff Minter whose career spans over 30 years. The recurring themes in Minter’s works are frenetic action and psychedelic experiences. All these abound in TxKa new arcade shooter for PS Vita.

The game starts off with the player in a wireframe setting being attacked by what looks like an army of angry ribbons. Soon you will discover that you are actually an oddly shaped spider(ish) creature that is crawling at extremely high velocity. Once your attacking abilities have been mastered, the environment will constantly reshape around you. Before you know it, you will find yourself up-side down fighting enemies from every direction. 

It is an exercise in minimalism; so much is achieved with few details. It is up to the player to make sense of the bizarre juxtapositions of graphics and sounds. Thanks to its unique style, TxK shines.

Plan to Live

Can planning really sustain us? Should we plan to survive or is project planning simply there to overcome obstacles when we are faced with them? Dr Rebecca Dalli Gonzi writes about a group of project management M.Sc. students who she asked to prepare a project plan. During their project students suddenly faced an unexpected turn of events. They were asked to counteract the problem and face the challenges that they encountered. This is their story

Planning is constant action; it never stops. If you are moving to a new house or country, you probably know what this means. Planning is pervasive, but can it get out of hand? What does planning a gap year mean? Do you plan every single minor detail or do you let loose to enjoy some spontaneity? If, for example, a couple is turning a shell apartment into a home it would involve a lot of tasks, planning leave in advance, and chasing the architect. They just might give up when a book shelf cannot get through the door. If we can plan to live, how would it help us get out of a rut when things really go wrong?

Managing your life is not that different to managing a project. When you manage a project you need a flexible plan that can meet the unplanned changing demands that life hurls at you. We live in a time when the efficiency of a service or project is based upon its ability to meet change or increasing demands. Would a project plan ensure that your plans run smoothly even when your life path starts changing its course?

Project managers cannot always foresee every eventuality when planning and managing a project. Once a project is underway many unexpected events can affect project target dates and resources. Planning at its simplest would mean better management and more knowledge, while at its most complex, it could mean more peace of mind. Trying to plan a complex project without a plan is like trying to cross the Pacific Ocean without a navigation system.

Positioning your project within vulnerable situations during the initial planning stages means your team can generate ideas develop creative solutions, and have a solid idea about the resources they have, time schedules they need to stick to, and budgets. This is exactly what helped Rita Sant manage change during an unexpected turn of events as soon as her project was launched.

Plan for Health

Sant designed a healthcare concept for homebound patients called ‘SMART At HOME’. It offered a combination of home health and community based services. She carried out in-depth research to come up with the right strategy, marketing analysis, project milestones, and deployment plan. Things seemed perfect on paper. Yet she ran into a game changer. Shortly after the project was launched, a competing company called HomesforYou was set up. It threatened to put her project on hold. HomesforYou offered similar concepts that which her project sponsors had in mind. However, Rita and her team had engineered some alternate options before the actual launch to keep the company ahead of the competition. Putting the project in a vulnerable position through an in-depth SWOT analysis (analysis of the strengths, weakness, opportunities, and threats of a project) helped show the project sponsors where their focus should be. Her focus was primarily on selecting target markets and helping attract new customers. Sant was able to direct her team towards the right networks. She identified gaps in the south of Malta, and worked directly with doctors and insurance providers to bring in new customers.

Sometimes, we are so taken up by our projects that we fail to see the obvious, to question the challenges whilst assuming we have already envisaged the end result. Project planning helps identify areas of weakness through tools like PESTEL analysis (analysis of political, economic, social, technological, environmental and legal factors that impact business), SWOT analysis, performance testing to verify strategies (plan workability), design of project think tanks, project recovery planning, contingency planning, and risk analysis (amongst other research areas). There is a lot of research behind project management.

Plan for Energy

Areas in the project that could have been overlooked suddenly become crucial. Sometimes being realistic is crucial to success. Another student, Joseph Borda, immediately received a notice that should his project exceed the proposed budgets the project sponsors would incur heavy fines. Borda was clear with his ideas from the start. Developing the power engineering workforce for the future is what he had in mind. His design of a solar panel array on the Malta International Airport car park would mean the generation of just enough energy to supply the airport. Proper time scheduling ensured that the project would be delivered within the specified time-frames. This could only work together with a proper team organisational structure and pre-designed hierarchical task network, which is the approach to automated planning where dependency among actions is given in the form of a network. A well-researched proposal helped Borda envisage proper scheduling to ensure the project was delivered within the specified time objectives, together with the team organisation structure and task hierarchies required to complete the task in time. Could a project schedule really have helped Borda stick to his time-frames? A project’s life or death hinges on its delivery date. Incurring fines meant that the project was narrowed down to a critical selection of what areas of the project had to be done in time.

“A solar panel array on the Malta International Airport car park would mean the generation of just enough energy to supply the airport”

The schedule alone would not have been a guarantee to a successful outcome. The initial stages of project research helped him and his team realise that the costings report for mounting and installation of the array was heavily over-priced. The project schedule helped mitigate the over-budget fines through the planning of phased installations and so areas that were going to be over-budget were shifted into a secondary phase. Typical project management requires attention to time, cost and quality. Once restrictions appear in one area, other areas begin to shift to accommodate new demands.

Having project management principles in place means there is a greater chance of fulfilling your objectives within the overall strategy and facilitating diagnosis of different situations as they occur. Just like captains need chart plotters or radars for distance and bearing to be able to manoeuvre ships in the worst conditions, so project managers use Gantt charts (a type of bar chart used to illustrate a project’s schedule) to help manoeuvre projects through time. Detailed planning helps translate business objectives into deliverables, provide a list of resource requirements, and a realistic assessment of project time-scales. Control measures can also be used to ensure there are no delays in target dates or to help identify team members who are not being productive.

Plan for Success

Measures of project progress can also be used to indicate when things are not moving as planned. Marc Spiteri decided to incorporate this approach into his project plan to meet a specific target: managing the Malta national rugby union team to qualify for the Rugby World Cup. Spiteri chose sports engineering as his field of study.

Spiteri’s primary objectives were to promote sports locally and to increase Malta’s appeal as a destination for sports tourism. The management plan was designed to operate on a three-point plan: first, having funding mechanisms in place for potential stakeholders and sponsors to bring in further investments; second, training and game planning aimed to work with the national team chosen to aid the organisational requirements for training camps and competitive games; third, a marketing strategy to tap into the local resources.

However, Spiteri was faced with a difficult challenge. Sponsorship for his project plan was threatened to be reduced if specific targets were not reached. Spiteri had knowledge and insight at the planning stage to moderate the negative effects of this cut. During planning he was able to set key performance indicators in areas of finance, training, competition and markets as part of the project design. The performance indicators allowed him to set targets to reach his ambitious goal. Rather than add a measure of control as an after-thought, he was able to integrate this as a whole concept. This meant that significant changes or shortcomings would be assessed against a measurement system, allowing a prompt response to take place with the significant action.

Plan for Death

Project control helps to ‘diagnose’ issues, plan for tackling weaker areas and adjust quickly to changes. It is normal for the team to assume that everything will work out well in the end but unpredictable behaviours, unfortunately, do happen. A lack of ownership can cause as many problems as unscheduled timing of events or project delays. A project plan gives the team the ability to envisage areas in which people conduct their activities and carry out their responsibilities. The more prepared the team is (in terms of knowledge and know-how of project plan), the quicker the recovery period. Planning is also useful as a tool when it is used to focus and highlight project needs to those involved. This is of particular importance when a project manager has to suggest different solutions to his or her client. Johann Farrugia was particularly good at providing a number of solutions for his concept of a digital cemetery when he had a major on-site problem with humidity.

“Information in cemeteries is handwritten meaning that some of the oldest records are today hardly legible. This is why cemeteries need an IT system to meet today’s needs”

Cemeteries are sacred, emotional spaces but also witnesses of human history. Information in cemeteries is handwritten meaning that some of the oldest records are today hardly legible. This is why cemeteries need an IT system to meet today’s needs. Farrugia identified the needs of all the different groups of people who make use of or work at a cemetery and figured out a system that allowed the public to request information easily. Through the website, staff and undertakers could access all the information they needed about gravesite location and burial details.

Farrugia faced problems with the testing system. Extreme humidity was interfering with the IT infrastructure limiting system usage. However, he integrated alternatives as part of his project planning phase thus being able to suggest solutions to his stakeholders and project investors. He was able to locate a secondary location system for supporting the project, thus eliminating completely the location of IT structures on-site. He also factored costings for any added insulation works required to counteract the problem and sought alternative zones that suffered from less humidity within the cemetery. 

In this case, since the unexpected problem arose at an early stage, the project manager could be flexible in his planning, allow for change, and bring in alternate ideas to deal with these issues. Having considered the options beforehand meant that he could reduce the impact of a sudden major change. 

In some cases, external events can trigger unexpected time delays. At times it can appear impossible to finish a project punctually, especially when there are delays in materials or suppliers. Sometimes a schedule should be consistent with your experience from previous projects. Your main focus should be on getting your critical requirements completed while avoiding distractions. The project management plan is critically dependent on the people who run it, design it, create it, and implement it. Moreover, increases in dependences increase time-frames.

Plan for Sustainability

Time-frames can quickly overrun when introducing sustainable measures into a residential development. Another student, Joslyn Magro, was keen to integrate into her project grey water reservoirs used to hold second class water for domestic use including lavatory use and landscaping photovoltaic panels, double glazing, and landscaping works. Sustainability has been an evolving theme to encourage environmental responsibility and promote intelligent decision- making with respect to energy use. Bad weather delayed the required materials that were being imported and this set the project back by a month.

By using a Gantt chart, Magro saw the negative effects of this delay. It would impact other installations and works. To reduce the burden, she scheduled architectural detailing and structural elements to run in parallel. This would reduce the dependency on strict delivery dates.

Information in cemeteries is handwritten meaning that some of the oldest records are today hardly legible. This is why cemeteries need an IT system to meet today’s needs

In her project plan she had also considered sourcing from different suppliers so she was able to negotiate costs affected by the delays. Once the materials were delivered on site, she could also introduce secondary teams of labourers to make up for the one-month back log. Costings saved during the delay, were used on a double-managed team unit. In her case, this may have proved to be the winning strategy as managing the on-site team as best as possible would help to counteract any further setbacks.

Taking advantage of constraints is the best way in project planning when possible. Projects revolve around expectations so it is better to envisage opportunity rather than to try control an event. Turning a shell apartment into a home might sound like a simple project in comparison to the ones discussed earlier but the problems would, theoretically, be very similar. Delays, supplier changes and exceeded budgets would surely impact your strategy along the way. Having strict milestones might be useful. It is not always necessary to consider worst-case scenarios but do consider carefully how much risk is actually acceptable. Most importantly, do not try to solve the problem, solve the cause. 

This article covers some work of the first cohort of students enrolled in the M.Sc. in Project Management launched by the Department of Construction and Property Management, Faculty for the Built Environment, University of Malta. The diversity of projects reflects the range of situations in which project management skills are being applied.

The School of Games

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.

FundMalta

Prof. Gordon Calleja

Picture a Maltese crowdfunding website dedicated specifically to locally based creatives. It would be supported and promoted by government entities to the Maltese public, based locally and abroad. For this to work the public sector plays a crucial role in promoting the site and educating the public on how crowdfunding works. 

The site creates a platform for followers of local creatives to contribute towards performances and products made by artists they love. Unlike sites like Kickstarter, products that can be digitally distributed or ordered will remain on the site doubling as a digital distribution platform for locally made works.

Wear Resistant Aluminium

Aluminium alloys have a low density and are easy to make. These qualities make them popular in the transport industry which can range from cars to planes. A low density makes them perfect to reduce weight in large metal structures. Unfortunately due to poor wear resistance, aluminium alloys can deteriorate quickly which severely limits their applications.

Dr Clayton D’Amato (supervised by Dr John C. Betts and Dr Joseph Buhagiar) modified the surface of an aluminium alloy (called A356) to overcome such limitations by improving wear resistance. D’Amato used a high power industrial CO2 laser to rapidly melt specific regions of the alloy’s surface. He simultaneously introduced additional alloying elements in the melt pool, which mix with the base metal to form new compounds that reinforce the soft aluminium surface. In this way, he formed a strong composite modified surface. Additional experimentation allowed D’Amato to reduce the loss of material due to wear by about 20 times. He optimised the conditions needed to laser process the surface of the aluminium in a uniform and repeatable manner. Adding nickel increased surface hardness 7-fold due to formation of aluminium-nickel compounds. Additional strength was achieved by adding hard ceramics to this aluminium-nickel structure. D’Amato created fine titanium carbide (TiC) particles in a matrix structure (pictured) by alloying a mixture of nickel, titanium and carbon (Ni-Ti-C). Aluminium treated in this way was much stronger.

The exact hardness was related to the mix of alloying elements in the modified surfaces. Hardness improved wear resistance, with large improvements in both surfaces alloyed with nickel and Ni-Ti-C. They lost 20 times less material than normal aluminium preventing severe damage.

Using a high powered laser allows improved wear resistance just where needed. This saves costs and increases versatility. The above technique could be used to manufacture aircraft pump parts, fittings and control parts, and in automotive water-cooled cylinder blocks.

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).

Onirim

BoardGame-Review

Solo board games are a funny business. First of all, nobody can catch you cheating. The temptation of closing an eye to a few little mistakes or ‘forgetting’ a rule are alluring. Second, you have nobody to rub the wrong way when you make a good move. Third, there’s nobody to beat. Board games initially strike us as a multi-player group affair, but solo games do exist. We have all played solitaire.

Onirim is a one-player card game. Although two people can play co-operatively I like it best solo. In Onirim you play as a ‘Dreamwalker’: a person stuck in a dream trying to find his way out before he is consumed by his own nightmares. To escape you must assemble a total of eight doors before the deck runs out. If it does you’re in trouble and stuck forever (till the next game).

By playing cards you move from room to room inside a labyrinth. When you manage to play three rooms of the same colour consecutively, a door of that colour ‘appears’, as in, you search for one inside the deck.

‘Hah, sounds easy!’ you might say. ‘Hah, you’re wrong’. There are nightmare cards, and nightmare cards are… horrible. You can only play one card per turn, and you might have a cunning plan set up cheerfully in your hand, but then a ‘nightmare’ happens, and you need to discard all your cards, and start over. Thankfully, the ‘nightmares’ can be dodged. Prophecies allow you to see the future, while keys negate a ‘nightmare’s’ effects.

I like Onirim. It is different, has gorgeous art, and is wonderfully balanced. The only downside is that it is out of print. But worry not, Dreamwalker! Onirim will be reprinted this year and you can get your dreamy paws on it… soon enough.
