Wood-cement compounds (WCCs) are composite materials made of wooden aggregates and mineral (cement) binders. These materials are widely used as prefabricated panels in the construction industry. A main obstacle for using casted WCC in construction elements is high shrinkage of the young product and frequently difficult workability of the mixes. This project addresses both of these problems by developing self-compacting low-shrinkage WCCs. Another objective of the study is to reduce cement content, which is typically very high in WCCs (500 to 700 kg/m3 of Portland cement). By replacing Portland cement with inert fillers or pozzolanic waste materials, the environmental impact of the WCCs can be lowered and a "greener" cement-based material is created. To assess the effectiveness of the developed recipes, WCC specimens are evaluated with regard to shrinkage, workability and mechanical performance. © 2016 Taylor & Francis Group, London.

Modern societies are eagerly looking for the integration of mobility and their urban living area to enable reliable and safe transportation, better efficiency and cost, comfort and low emissions for the environment. The trends are obvious, however, providing a hybrid/electrical car is only one part of the full picture. The standard customer is still very reluctant to buy a full electrical vehicle (FEV). The reasons are manifold but the most important is unpredictable mileage and limited autonomy. The prediction of the cruising range without any restrictions in terms of safety and comfort is a key point: essential is D-P-C (Drive safely, Park easily and Charge conveniently).\n\nToday a nominal 100km range might vary from 50 to 130km in reality, depending on various conditions such as temperature and profile of the route. Increasing the capacity of the battery is no viable option because it results in a drastically increase in cost and weight of the car. Through eDAS we will limit the negative impact of high and low environment temperatures from -50% today to a maximum of -20% of the reachable range in electric vehicles, which corresponds to an improvement of 60% compared to state of the art. We will bring the infrastructure of the EV to the optimum operating temperature range for faster fast charging, pre-conditioned passenger compartment and battery, also safety and convenience features, such as de-iced windows during winter time based on the available infrastructure without adding cost and weight based on new designs and architecture combining battery, e-motor, electronics, charger and energy management.\n\nAddressing this challenge of the architecture of all subsystems of the complete EV requires a wide area of expertise, and in consequence leads to a large consortium. To develop and demonstrate the innovative hardware and software solutions, including new materials, adequate resources and budget are required.

The path-breaking HAVEit proposal aims at the long-term vision of highly automated driving. Within this proposal important intermediate steps will be developed, validated and demonstrated. These intermediate results on the one hand offer high potential for exploitation within 3-5 years after HAVEit and on the other hand form the ideal basis to integrate further next generation ADAS (highly automated functionalities) by adding software modules.\n\nHAVEit will significantly contribute to higher traffic safety and efficiency for both passenger cars and trucks, thereby strongly promoting safe and intelligent mobility of both people and goods. The strong HAVEit safety and efficiency impact will be generated by three measures:\n\n(i) By optimizing the task repartition between driver and co-driving system (ADAS) in the joint system. As 95% of all accidents are caused by driver mistakes, it is very important to ensure the driver is in the loop when required to make sure he or she is able to react properly in a potentially critical situation. Within HAVEit a radically new approach will be developed: Instead of just switching off an ADAS system in case of an impending potentially critical situation, a step-by-step-approach will be used to transfer the driving task back from the automated system to the driver. \n\n(ii) By further developing and implementing the failure tolerant, safe vehicle architecture including advanced redundancy management (from the SPARC predecessor project) to suit the needs of highly automated vehicle applications and to arrive at higher system availability and reliability.\n\n(iii) By developing and validating next generation ADAS directed towards higher level of automation compared to the current state of the art: HAVEit integrates 7 cutting edge highly automated vehicle applications for both passenger cars and trucks, e.g. automated assistance in roadworks, automated queue assistance, temporary autopilot, active green driving.

Surgical implant for treating fractures of long bones, notably of the femur, having an intramedullary section (52) of elongated shape, adapted for being inserted into the medullary cavity (37), an extramedullary section (56) substantially parallel to the intramedullary section (52), a deformable curved loop (57) connecting the intramedullary section (52) to the extramedullary section (56), an inclined screw (61) traversing said intramedullary section (52) and said extramedullary section (56). By deforming the loop (57), a continuous adjustment of the angle () of the cephalic screw (61) and thus an optimal adaptation of the implant to the individual anatomy can be achieved. Thanks to its geometry, this implant induces a protection of the greater trochanter and limits the mechanical loads between the cephalic screw (61) and the rest of the implant.

Ensure wellbeing for each of us is a first necessity for peace and development of society while preserving the environmental balance of the blue planet. Today's society is faced with major challenges such as the supply of energy, water, food, etc. Refrigeration is an important factor in the modern world. It is vital before life (sperm banks), for life (conversation food, medicine,.), and after life (preservation of human organs and tissues). However the negative impact of refrigeration on the environment is visible and, consequently, refrigeration systems are subject to prescriptive regulation. This regulation provides a great opportunity for the emergence of new refrigeration technologies and new product markets. In recent years, magnetic refrigeration is considered as a serious alternative for conventional systems. Today proof of the concept is established. Therefore what remains is to provide systems for the society. © 2013 Elsevier Ltd and IIR. All rights reserved.

While there is a growing awareness of the 're-emergence' of working poverty, this topic remains relatively under-researched. This article provides an encompassing review of the literature dealing with the situation in Europe, North America and the Antipodes, with a focus on the theoretical models found in this literature, the definitions used and the risk groups identified. The main conclusion is that most publications were not based on a specific theoretical model, which has led to a flurry of definitions; moreover, conclusions on certain risk groups are divergent. The end of the article focuses on what remains to be done, because there are good reasons to think that working poverty might become a more pressing problem in the near future, and social policy researchers will have to have good theoretical frameworks and robust evaluation strategies in the years to come. © The Author(s) 2013.

Texture-based computerized analysis of high-resolution computed tomography images from patients with interstitial lung diseases is introduced to assist radiologists in image interpretation. The cornerstone of our approach is to learn lung texture signatures using a linear combination of N-th order Riesz templates at multiple scales. The weights of the linear combination are derived from one-versus-all support vector machines. Steerability and multiscale properties of Riesz wavelets allow for scale and rotation covariance of the texture descriptors with infinitesimal precision. Orientations are normalized among texture instances by locally aligning the Riesz templates, which is carried out analytically. The proposed approach is compared with state-of-the-art texture attributes and shows significant improvement in classification performance with an average area under receiver operating characteristic curves of 0.94 for five lung tissue classes. The derived lung texture signatures illustrate optimal class wise discriminative properties.

Magnetic heating, refrigeration and energy conversion have caused awareness of being promising future environmentally benign technologies with much potential to enter some existing markets. An increased research activity is observed, which to the end of the year 2010 lead to approximately forty-two prototypes. As most of these machines contain solid linear moving or rotating beds - consisting of magnetocaloric material - through static magnetic fields or moving magnets, which sweep a magnetic field over a static bed, all researchers face more or less the same problems. These concern materials, fluids, design and the operation characteristics. In this article innovative new system ideas are presented, which may have the potential to overcome existing barriers. The article is a proposal to the research community in the field of magnetocaloric technologies for future R&D activities. Taking into account all the limits and problems that researchers are facing at present, the best chance to bring magnetocaloric technologies to the market is to try some substantially new approaches that go beyond the present state-of-the-art. © 2009 Elsevier Ltd and IIR.
