This paper describes an attempt to analyze, understand and eventually to prevent cheating. It was done for an introductory course in computer science located in the second semester of a three-year bachelor program and is backed by a detailed statistical analysis that was possible thanks to the incorporation of an E-learning platform (Moodle). The experiment was conducted over two years. In the first year possible sources and ways of cheating had been analyzed. Based on these findings, means to prevent cheating have been identified. In the second year the effect of the selected measures was tested. The experiment showed that at least some types of cheating can be significantly reduced. However, reducing the possibilities for cheating does not motivate all students to actually show a true effort. © 2017 IEEE.

Background: RESTful web services nowadays are state-of-The-Art in business transactions over the internet. They are however not very much used in medical informatics and in clinical research, especially not in Europe. Objectives: To make an inventory of RESTful web services that can be used in medical informatics and clinical research, including those that can help in patient empowerment in the DACH region and in Europe, and to develop some new RESTful web services for use in clinical research and regulatory review. Methods: A literature search on available RESTful web services has been performed and new RESTful web services have been developed on an application server using the Java language. Results: Most of the web services found originate from institutes and organizations in the USA, whereas no similar web services could be found that are made available by European organizations. New RESTful web services have been developed for LOINC codes lookup, for UCUM conversions and for use with CDISC Standards. Discussion: A comparison is made between "top down" and "bottom up" web services, the latter meant to answer concrete questions immediately. The lack of RESTful web services made available by European organizations in healthcare and medical informatics is striking. Conclusion: RESTful web services may in short future play a major role in medical informatics, and when localized for the German language and other European languages, can help to considerably facilitate patient empowerment. This however requires an EU equivalent of the US National Library of Medicine. © 2017 The authors and IOS Press.

The objective of POLLUX is to develop a distributed real time embedded systems platform for next generation electric vehicles, by using a component and programming-based design methodology. Reference designs and embedded systems architectures for high efficiency innovative mechatronics systems will be addressed with regard to requirements on composability, networking, security, robustness, diagnosis, maintenance, integrated resource management, evolvability and self-organization. Next generation EVs will begin the convergence between computer and automotive architectures: future automobiles will be mechatronic systems comprising a multitude of plug-and-play and self configurable peripherals. Peripherals will be embedded systems containing hardware, algorithms, software. The architecture will be based on distributed energy while the propulsion systems will adopt radical new control concepts. Sensing, actuation, signal processing and computing devices will be embedded in the electronic equipment, electrical motors, batteries and the mechanical parts as well. The systems used to control the chassis and the power train will form the computing engine that automates lower level tasks during vehicle use (driver assistance, terrain evaluation, predictive battery management) and will enable future higher level functionalities (auto pilot), by means of novel human-machine interfaces. POLLUX addresses the embedded system needs for the next generation electric vehicles by exploiting the synergy with the ENIAC E3Car project which aims to develop nanoelectronics technologies, devices, circuits, and modules for EVs in preparation for the launch of a massive European EV market by 2015-2020. The project considers both vertical integration and horizontal cooperation between OEMs, hardware/software/silicon providers to build a solid, embedded-systems European industry while establishing standard designs and distributed real-time embedded-systems platforms for EVs.

Enhancing interconnectivity of short & long distance transport networks through passenger focused interlinked information-connectivity IC-IC will develop an ICS (InfoConnectivity System), involving the airports of Amsterdam, Frankfurt, Paris & Vienna, related ground transport & airlines, representing both short- & long-distance transport. Many stakeholders will get involved in a Stakeholders Forum & Conference. By providing currently missing information which travellers already wish to have with regard to facilities & services of their next immediate destination and/or next transport provider(s), the ICS is expected to improve the travelling experience implying a possible gain of time, and improve change between transport modes. Much of such information can be provided while waiting, e.g. in the airport train/bus, the lounge, the airplane, utilizing camera mobile phones to connect to information provided by QR (Quick Response) codes, and mobile phones fitted with NFC (Near Field Communication) able to connect to respective tags. To provide ICS information to the multi-lingual target group of travellers, a language translation software will be employed to offer all information in 14 languages with English as the reference language. Requirements of the ageing population are considered by utilizing the Age Explorer, a suit that lets test persons experience the obstacles old persons encounter when moving, filling out forms, operating Self Check-in, or a ticket machine. 1000 persons in 3 countries will be interviewed, information of Stakeholders collected, model ICS applications developed & implemented to serve in real live situations. The effectiveness of the InfoConnectivity improvements will be assessed with regard to information made available which otherwise a traveller would not have been able to access plus gained time & ease of passenger transfer between transport networks. Based on this, an ICS handbook will be elaborated.

Following the Green Car Initiative (GCI) included in the European Economic Recovery Plan there is a high demand for electrification of transport in Europe. There are currently several concepts for FEV (fully electric vehicle) and HEV (hybrid electric vehicle) that support this electro mobility demand. The development and improvement of the different concepts require a huge effort in analysis, design, implementation and testing and not to forget feeding back experience, results and knowledge to new generations of Electric Vehicles. Advanced modelling tools and testing procedures going from one-dimension to three dimensional approaches have a fundamental role to play in optimizing during the earliest project phases for the energy dimensioning of FEV & HEV as well as their energy management strategies while reducing projects development lead-time as well as to build-up requirements for subsystems and their related control units. Research in this project will focus on the development and validation of numerical simulation tools, virtual prototyping and advanced physical testing procedures and on the standardization of such tools in order to: Investigate solutions for improving the efficiency and performance of future generation EV and their constituent components and sub-systems that may be critical from the energy efficiency point of view. The development of these sub-systems is however excluded. Assess the effect of different sub-systems solutions in terms of energy efficiency and related increase of autonomy on different specific real life driving cycles that will take into account traffic constraints, road slope evolution, etc. Verify technological feasibility and economic viability of the advanced solutions proposed. ASTERICS project aim is to develop advanced modelling and testing tools and methods that will be the base for future developments of FEV & HEV trough all Europe, contributing to the competitiveness in this sector, in all its aspects.

The SOLUTION project mobilises public / private resources to build showcases of energy self sufficient communities in Austria, Croatia, Finland and Switzerland (together with the associated Slovenian community) with a strong potential for replication throughout Europe. SOLUTION is designed to respond to the needs of an effective take-off of the European SET-plan by demonstrating novel applications of different energy technologies and techniques integrated in an intelligent way within model areas. Although the individual demonstration projects are independent from each other, being designed to fulfil local energy needs and using local resources, there are many similarities between them. The implementation plan is a mix of local and integrating activities, such as 1)sharing latest research results especially of electricity storage, customer behaviour and intelligent RES integration, 2)demonstrating appropriate energy solutions in order to reach self-sufficiency, 3)establishing adequate business environment favourable for CONCERTO demonstrations, 4)serving as benchmark for sustainable communities and spreading best-practice, 5)developing a transparent SOLUTION model for immediate replication. By deploying an interdisciplinary approach, an innovative / cost-efficient mix of actions, a set of sustainability oriented solutions will be pointed out and transferred to and among the identified target groups of SOLUTION. The outcomes and related benefits will be fully exploited by an effective range of actions generating local activities with high visibility character together with the major stakeholders. Thus the members of the consortium will act as forerunners towards the low carbon future. The consortium composition is a balanced mix of representative model areas ready for demonstration and of 17 communal, industrial and scientific European partners (incl. 6 SMEs) with a wide geographical spread, complementary resources and expertise.

Road transport is the second largest EU producer of CO2, one of the greenhouse gases responsible for climate change. While some improvements in efficiency of road vehicles have been achieved, continued growth in traffic and congestion mean that CO2 emissions from road transport have grown overall. At the same time rising fuel prices and supply instability also give pressure for increased efficiency. The EC has set targets for the average CO2 emissions of new vehicles to be 120 g/km by 2012, with further reductions needed to achieve a 40% reduction in CO2 from light passenger vehicles by 2020. The EE-VERT project will develop technologies that will play a key part in achieving these goals. Despite improvements in individual areas of the modern vehicle such as powertrain, a considerable amount of energy is wasted due to the lack of an overall on-board energy management strategy. Further electrification of auxiliary systems (the more electric vehicle) promises energy and efficiency gains, but there is a need for a co-ordinated and predictive approach to the generation, distribution and use of energy. In the state-of-the-art, power is generated with little knowledge of the actual loads, and some systems (both electrical and mechanical) consume power continually regardless of demand. The introduction of systems such as alternator set-point control and EPAS are first steps towards optimising energy use but such systems operate in isolation. This project will develop strategies in conventional vehicles, also applicable to hybrids, for overall energy management (thermal and electrical) to reduce fuel consumption and CO2 emissions. Also, the need for the strategies to guarantee power supply to safety-related systems will be considered. It is estimated that EE-VERT technologies can reduce CO2 emissions by around 10% for a car. For a large vehicle savings of around 40% of the CO2 that is created by an auxiliary system such as climate control is possible.

Engineering Failure Analysis | Year: 2010

For hot rolling, tools are nowadays made of cemented carbides. In service, these rolls suffer from wear and thermal fatigue. Due to the properties of ceramics, their use could cause improvements in tool behaviour. In field tests - when rolling materials with high deformation resistance - cracks developed in the silicon nitride rolls, which grew for a long time period before large parts of the rolls broke apart. In more moderate rolling conditions the rolls operated safely. A FE model is used to analyse the in-service behaviour of cracks in the silicon nitride rolls. For the observed crack path the stress intensity factor of the cracks is determined using the weight function method. It increases up to a crack depth of around 0.35 mm and then decreases again with increasing crack depth. This explains the observed pop-in-type growth of cracks after an overload. Depending on the rolled materials, the popped in cracks have a length of up to 1.2 mm. The further growth of the cracks to a length of several millimetres, which is caused by a fatigue growth mechanism, needs several thousand additional revolutions. © 2009 Elsevier Ltd.
