In this paper a small-scale energy system called emergency container is presented. This container has lots of applications and can be designed as stationary solution in remote areas such as rural electrification and a mobile solution for disaster situation, military purposes and exploration teams. In this study the container is a hybrid PV/wind/engine energy system that is designed to provide electricity and drinkable water for 1000 person in disaster situations. A transient model implemented in Transient Simulation System (TRNSYS) program is developed and performance of the system during one-year operation for two locations (Nairobi in Kenya and Nyala in Sudan) with relatively high solar insolation is analyzed. The result of the model is significantly important in order to choose the right size of the different components. Due to the fluctuations of solar and wind energy as well as the importance of the battery life cycle, there is a need to have a smart power management and an appropriate fast response control system. In order to achieve it and to fulfill the energy demand as much as possible through renewable energies, a dispatch strategy is introduced and a control algorithm is applied to the model. This control algorithm has increased system reliability and power availability. The transient simulation shows that the share of power generation by solar energy is 63% and 80% and the share of wind power is 27% and 12% in Nairobi and Nyala respectively. It means that most of the energy demand (around 90%) can be covered by renewable energy. This results in significant mitigation of environmental issues compared to using only diesel engine that is a common solution in disaster situations. © 2014 Published by Elsevier Ltd. Source

This studio explains the application through the application of the ProKEx architecture is used to improve the process of allocation of funding at the European Institute of Innovation and Technology (EIT). The mission of the EIT is to grow and capitalize on the innovation capacity and capability of actors from higher education, research, business and entrepreneurship from the EU and beyond through the creation of highly integrated Knowledge and Innovation Communities (KICs). This case offers the scenario of a complex application where a fragmented process with several actors is dealing with the different domains of knowledge of each KIC. Starting from the Business Process Model, applying text-mining techniques we extract the ontology elements from the activity description and converted into an Ontology of the process domain. By the critical analysis of the information contained in the model, we gain the relevant information to improve the current approach. © 2014 Springer International Publishing. Source

Operator-governed opportunistic networks (ONs), which are dynamically created, temporary coordinated extensions of the infrastructure, are the first ingredient for the proposed networking solution. This article presents the concept of cognitive management systems (CMSs) for the management of ONs, their coordination with the infrastructure, and evaluation of an indicative test case as a proof of concept for the aforementioned approach. © 2011 IEEE.

Minecraft creator Mojang has quietly started offering a 'standalone' version of Java with its loader as part of a new approach that should limit the effects of the software's infamous insecurity on tens of millions of desktop gamers. Until now, running Minecraft has meant having Java installed at a system level, which given its historically flaw-ridden stats presents a security risk for a computer even when Minecraft is not being used. Given that an unknown number of users only install Java to play the famous game, integrating that into the launcher keeps this exposure to a minimum and in theory overcomes the issue of users who don't bother to update Java to stay ahead of software flaws. The company appears to have been testing this feature in recent months without making much fuss but has now included the technology for the Windows PC Edition of Minecraft (OS X support is promised by year end) for new downloads of the launcher. As we understand it, users running the current version will need to update their software and then make an adjustment in the Minecraft Profile to point at the new javaw.exe executable. Full instructions on how to do this have helpfully been posted on the How-To Geek website. According to HTG, not only would users inadvertently running 32-bit see a significant increase in performance, even an up-to-date 64-bit Java installation might see a boost in FPS. The former is likely although the latter is hard to understand. Essentially, it's the same Java but just called by the application rather than through Windows. "A really, really big percentage of our players use 32-bit java on 64-bit machines, and they don't even know. 64-bit java runs significantly better in a lot of scenarios for Minecraft, so it's just a waste that they do this," said an unnamed Minecraft developer on Reddit some weeks ago. Exactly how long the new Java-free install has been available is not clear but it appears to data back to the middle of January. The Minecraft website has a single line noting that Windows users no longer needed to install Java to run the software. A few points. De-installing Java in favour of Minecraft's install won't suit anyone who needs Java for something other than Minecraft. Users should also check that the version in use by the game is kept up-to-date because in theory there could be some delay between Oracle issuing patched versions and Mojang making them available. Numerous analyses have identified Java as the top source of both unpatched known flaws and serious zero-days and yet the world keeps turning and little seems to change. Some users have de-installed Java completely but of course that stops super-game Minecraft from working. Many just ignore the issue, even running completely out-of-date versions. For background, Danish security firm noticed a staggering 145 software flaws affecting Java in the third quarter of 2014 alone. In total, 77.65 percent of users running Personal Software Inspector (PSI) were running Java with around half running unpatched versions covering all versions including end of life. Despite its vulnerability and continuing popularity with attackers, Java has added some security features over the years, including December 2012's Java Version 7 Update 10 which made it possible to disable Java browser plug-ins. Wolfgang Kandek, CTO of security firm Qualys, suggested that the security benefits were welcome. "Including Java inside its own installation is a good move by the Minecraft team. It enables Minecraft to have the best version of Java available for its type of processing, giving better performance. On top of that they can turnoff specific unnecessary items such as the browser integration part that are a huge win from a security perspective." he said. "My backup program CrashPlan uses the same mechanism and it has been instrumental in making my Java installations on my desktop simpler - I don't have Java on the desktop anymore. I wish other programs such as Symantec AV for Mac went the same route." "It reduces the Java threat to zero." Mojang is now part of Microsoft's stable having been bought by the firm last September for $2.5 billion.
The damning report released by auditors last week on the European Institute of Innovation and Technology (EIT) was predictable. Since it was conceived about 10 years ago, the EIT — a €3-billion (US$3.4-billion) mechanism that is supposed to stimulate innovation in areas that are considered to be among Europe’s foremost societal challenges — has suffered more than just teething problems (see page 291). As the auditors pointed out, the EIT has struggled to align business and research communities in sectors such as public health or the development of clean technologies in a way that could address common market failures. The EIT as a whole has still to prove that its existence makes a real difference. To do so, managers must monitor more closely — and demonstrate more plausibly — whether the substantial tax money spent on the EIT triggers the desired effects on innovation. Creating commercially relevant knowledge through basic research needs incentives. But innovation is not something that technocrats (or bureaucrats) can easily order. Innovation and bureaucracy are in fact not a good match — too much of the latter is one of the reasons why the EIT has failed to meet expectations. The audit report comes as proposals swirl for yet another European Union innovation body — one to be called the European Innovation Council. The idea might seem inappropriate at a time when top-down approaches to stimulate absent market forces have been weighed and found wanting. But the EIT’s failure is a good occasion to think about what is missing. It’s a given that the EU needs to unlock its innovative potential to make its ageing societies fit for the future and create jobs for the next generation. So why are the EU’s economic competitors in North America and Asia more able to transform the ideas of academic scientists and engineers into marketable goods and services? It is not for want of good intent and trying. European universities have long ceased to be academic havens where students and staff ponder the wonders of the world in splendid isolation. Science parks, incubators and technology-transfer offices have become the rule on European campuses. Also, the European Commission’s €80-billion Horizon 2020 research programme has a strong emphasis on producing applicable science in partnership with small and large companies. Other schemes — EU Finance for Innovators, Joint Technology Initiatives, European Innovation Partnerships and the EU Innovation Union — likewise intend to obtain the maximum economic return on research money. And yet the quality in question is in short supply. Why hasn’t the investment and effort led to greater innovation? The byzantine complexity of the EU’s innovation support is making it less effective than policymakers would like it to be. There are just too many programmes, too many levels, too many forms, bodies, requirements and exceptions. The bureaucratic confusion is not stifling innovation all together — the EU’s graphene flagship project and countless small entrepreneurial success stories are sufficient evidence that some things do work very well. But given the EIT dilemma, Europe’s leading research universities have rightly reminded policymakers that streamlining and simplifying EU innovation instruments is a better approach to stimulating the sought-after quality than adding another layer of complexity on top of it. This does not mean that a European Innovation Council — for which the European Commission issued a call for ideas in February — would necessarily be wasted money. But such a council must seek to optimize, rather than add to, the existing portfolio of initiatives and mechanisms. Europe’s paradoxical innovation bureaucracy might still benefit from a high-level advisory body comprising competent business leaders, researchers and policy experts. So, incidentally, might the floundering EIT.
