FOTsis (European Field Operational Test on Safe, Intelligent and Sustainable Road Operation) is a large-scale field testing of the road infrastructure management systems needed for the operation of seven close-to-market cooperative I2V, V2I & I2I technologies (the FOTsis Services), in order to assess in detail both 1) their effectiveness and 2) their potential for a full-scale deployment in European roads.\n\nSpecifically, FOTsis will test the road infrastructures capability to incorporate the new cooperative systems technology and provide the following services in four European Test-Communities (Spain, Portugal, Germany and Greece) regrouping 9 Test-Sites:\n\nS1: Emergency Management\nS2: Safety Incident Management\nS3: Intelligent Congestion Control\nS4: Dynamic Route Planning\nS5: Special Vehicle Tracking\nS6: Advanced Enforcement\nS7: Infrastructure Safety Assessment\n\nUsing an integral and comprehensive approach, FOTsis will therefore review the road infrastructure and communication networks required to secure a proper connectivity from the traffic control centres (and all the information they already have available, enhanced with the V2I data) with the users/vehicles.\n\nRelying on the common European and open ITS architecture guideline proposal (supported by the project COMeSafety), able to incorporate available and future ITS services and systems, FOTsis aims to contribute to the safety, mobility and sustainability challenges faced nowadays by the European road transport system.\n\nThe project represents a major step forward to better connect vehicles, infrastructures and traffic management centres, the main focus being placed on the responsibilities of the road operator.

An increase in energy intake and/or a decrease in energy expenditure lead to fat storage, causing overweight and obesity phenotypes. The objective of this review was to analyse, for the first time using a systematic approach, all published evidence from the past 8 years regarding the molecular pathways linking non-shivering thermogenesis and obesity in mammals, focusing on mechanisms involved in brown adipose tissue development. Two major databases were scanned from 2006 to 2013 using 'brown adipose tissue' AND 'uncoupling protein-1' AND 'mammalian thermoregulation' AND 'obesity' as key words. A total of 61 articles were retrieved using the search criteria. The available research used knockout methodologies, various substances, molecules and agonist treatments, or different temperature and diet conditions, to assess the molecular pathways linking non-shivering thermogenesis and obesity. By integrating the results of the evaluated animal and human studies, our analysis identified specific molecules that enhance non-shivering thermogenesis and metabolism by: (i) stimulating 'brite' (brown-like) cell development in white adipose tissue; (ii) increasing uncoupling protein-1 expression in brite adipocytes; and (iii) augmenting brown and/or brite adipose tissue mass. The latter can be also increased through low temperature, hibernation and/or molecules involved in brown adipocyte differentiation. Cold stimuli and/or certain molecules activate uncoupling protein-1 in the existing brown adipocytes, thus increasing total energy expenditure by a magnitude proportional to the number of available brown adipocytes. Future research should address the interplay between body mass, brown adipose tissue mass, as well as the main molecules involved in brite cell development. © 2014 The Authors.

Participatory sensing has emerged as a novel paradigm for data collection and collective knowledge formation about a state or condition of interest, sometimes linked to a geographic area. In this paper, we address the problem of incentive mechanism design for data contributors for participatory sensing applications. The service provider receives service queries in an area from service requesters and initiates an auction for user participation. Upon request, each user reports its perceived cost per unit of amount of participation, which essentially maps to a requested amount of compensation for participation. The participation cost quantifies the dissatisfaction caused to user due to participation. This cost is considered to be private information for each device, as it strongly depends on various factors inherent to it, such as the energy cost for sensing, data processing and transmission to the closest point of wireless access, the residual battery level, the number of concurrent jobs at the device processor, the required bandwidth to transmit data and the related charges of the mobile network operator, or even the user discomfort due to manual effort to submit data. Hence, participants have strong motive to misreport their cost, i.e. declare a higher cost that the actual one, so as to obtain higher payment. We seek a mechanism for user participation level determination and payment allocation which is most viable for the provider, that is, it minimizes the total cost of compensating participants, while delivering a certain quality of experience to service requesters. We cast the problem in the context of optimal reverse auction design, and we show how the different quality of submitted information by participants can be tracked by the service provider and used in the participation level and payment selection procedures. We derive a mechanism that optimally solves the problem above, and at the same time it is individually rational (i.e., it motivates users to participate) and incentive-compatible (i.e. it motivates truthful cost reporting by participants). Finally, a representative participatory sensing case study involving parameter estimation is presented, which exemplifies the incentive mechanism above. © 2013 IEEE.

Renewable fuels, as an alternative fuel, can be produced from different biomass types such as vegetable oils of various origins, waste cooking oils and fats. The most common biofuel is FAME biodiesel that produced via transesterification of vegetable oils. Due to many disadvantages of FAME biodiesel new technologies are under investigation for the production of second generation biodiesel such as Fischer-Tropsch and hydrotreated vegetable oils, waste cooking oils and fats. In the present study the main properties that specify the quality of renewable diesel fuels were examined and a detailed comparison between different types of these fuels was performed. The renewable diesel fuels examined include FAME biodiesel, green diesel, Fischer-Tropsch diesel, hybrid diesel and white diesel. © 2013 Elsevier Ltd.
