Virtual Desktop Infrastructure (VDI) is a new generation of cloud service in which users operating systems execute in a cloud data center. Users can access their desktops and applications by using thin client devices. This thin client is consisting of only a screen attached with low power CPU. This new paradigm of delivering remote desktop provides benefits in terms of flexibility, cost reduction, data security and energy saving which are the green benefits from using VDI. VDI becomes an important technology in green computing and energy saving. In this paper, we present and review the green benefits for using VDI in large and small organizations. The usefulness and energy-saving features of VDI are also illustrated by some experiments. [less ▲]

A multitude of factors contribute to complex diseases and can be measured with ‘omics’ methods. Databases facilitate data interpretation for underlying mechanisms. Here, we describe the Virtual Metabolic Human (VMH, www.vmh.life) database encapsulating current knowledge of human metabolism within five interlinked resources ‘Human metabolism’, ‘Gut microbiome’, ‘Disease’, ‘Nutrition’, and ‘ReconMaps’. The VMH captures 5180 unique metabolites, 17 730 unique reactions, 3695 human genes, 255 Mendelian diseases, 818 microbes, 632 685 microbial genes and 8790 food items. The VMH’s unique features are (i) the hosting of the metabolic reconstructions of human and gut microbes amenable for metabolic modeling; (ii) seven human metabolic maps for data visualization; (iii) a nutrition designer; (iv) a user-friendly webpage and application-programming interface to access its content; (v) user feedback option for community engagement and (vi) the connection of its entities to 57 other web resources. The VMH represents a novel, interdisciplinary database for data interpretation and hypothesis generation to the biomedical community. [less ▲]

The nonlinear heat transfer process occurring during hybrid laser welding was simulated using the Virtual-node Polygonal Element (VPE) method within the framework of the Finite Element Method (FEM). To achieve robustness in large-scale welding simulations, a dynamic mesh refinement with quadtree and octree data structures was used in the welding region. Accuracy, convergence and efficiency were verified by solving two and three dimensional problems. It is found that the present VPE can successfully simulate the hybrid laser welding process with good accuracy and convergence. The adaptive refined mesh box can synchronously move with the welding heat source, which dramatically reduces the number of field nodes. Compared with the standard FEM,the VPEM requires only approximately 42% of the total degrees of freedom used in standard FEM for the same accuracy. Furthermore, we compare the computational cost and accuracy of the method to that of the finite element method, the edge based virtual node polygonal element/virtual node method, the edge-based Smoothed Point Interpolation Meshless Method (ES-PIM), the edge-based Element (ES-PIM) the Element Free Galerkin (EFG) method and the Meshless Local Petrove-Galerkin Petrov-Galerkin (MLPG) method. Compared to all those methods, the proposed scheme is found competitive in terms of computational cost versus accuracy, and benefit from a simple implementation. © 2012 Elsevier B.V.

With rapid transfer of many forms of social inquiry through structured questionnaires to the Web it is increasingly important to explore whether the Web is indeed a ‘socially neutral’ research tool as many believe. Because of the graphical and interactive nature of the Web and the context of global environment, social desirability effects in Web surveys may be different from with other self-administered methods, which usually reduce them. In addition, increased use of interactive services, such as multiple user domains, interactive chat rooms and interactive online games encourages widespread adoption of ‘virtual personas’ on the Web. It is thus important to explore how participation in such interactive services may mitigate potential benefits of the Web for social research. Our research explores whether those who are frequent participants in so-called ‘alternate realities’ on the Web are more likely to present their ‘virtual personas’ or their ‘real selves’ when answering questions in Web surveys. Users of interactive services are identified in a large national Web survey of Internet users in Slovenia within the project RIS (http://www.ris.org) at the Faculty of Social Sciences, University of Ljubljana. They are asked a variety of questions relating to self-image that are known to be subject to social desirability bias. At the end of the survey they are asked for their telephone number. A random sample of respondents from the population of non-users of interactive services is also selected. Both groups are then administered a telephone survey, with the key self-presentation and social desirability items replicated. We then compare the responses to the telephone survey with those provided in the Web survey. Our hypothesis is that those who are regular participants in interactive services are more likely to present themselves in a different light on the Web than on the telephone, relative to the non-user group.

The technical complexity of automotive Cyber-Physical Systems (CPS) traditionally demands high development and validation efforts. Due to the new technologies entering the automotive market, such as Highly Automated Driving (HAD) (>= SAE L3) and connected infotainment, the overall system complexity is currently increasing significantly, challenging traditional system development methods and requiring new approaches for validation and verification (V&V). In parallel, new Electric/Electronic (E/E) architecture patterns are emerging in the automotive industry, distributing the functionalities across several multi-core Electrical Control Units (ECU) connected via Ethernet-based in-vehicle networks. This distributed approach leads to complex inter- and intra-ECU timing relations challenging the concept of freedom from interference according to the ISO 26262, and adding another dimension of effects analysis during V&V. This work enhances a cyber-physical functional simulation tool to include timing effects in distributed cause-effect chains and multi-technology-communication networks (incl. Ethernet and CAN). The resulting simulation allows the system designer to evaluate the impact of timing properties on a given distributed vehicle function, enabling an early validation of the system, avoiding rework during later stages of the development process resulting from wrong design choices.

The presentation defends a fullblooded, 'thick' virtue-theoretic account of epistemic normativity. If we think of beliefs as under the control of rational agents, by means of their rational capacities, the norm of excellence (or 'virtue') applies to doxastic action as well as any other rational action. An argument is presented to the effect that the knowledge norm is the right norm of belief. [less ▲]
