Although it is a widely held belief that social capital facilitates knowledge sharing among individuals, there is little research that has deeply investigated the impacts of social capital at different levels on an individual's knowledge sharing behavior. To address this research gap, this study combines a multilevel approach and an optimal network configuration view to investigate the multilevel effects of social capital on individuals' knowledge sharing in knowledge intensive work teams. This study makes a distinction between the social capital at the team-level and that of social capital at the individual level to examine their cross-level and direct effects on an individual's sharing of explicit and tacit knowledge. A survey involving 343 participants in 47 knowledge-intensive teams was conducted for testing the multilevel model. The results reveal that social capital at both levels jointly influences an individual's explicit and tacit knowledge sharing. Further, when individuals possess a moderate betweenness centrality and the whole team holds a moderate network density, team members' knowledge sharing can be maximized. These findings offer a more comprehensive and precise understanding of the multilevel impacts of social capital on team members' knowledge sharing behavior, thus contributing to the social capital theory, as well as knowledge management research and practices. © 2013 Elsevier Ltd.

Hyperthermia as a heat therapy is the procedure of raising the temperature of a part of or the whole body above normal for a certain period of time. Based largely on delivery methods, therapeutic hyperthermia falls under three major categories: local, regional, and whole-body. It may be applied alone or jointly with other modalities such as radiotherapy, chemotherapy, radiochemotherapy, and gene therapy. Because of the individual characteristics of each type of treatment, different types of heating systems have evolved. This paper provides an overview of possible mechanisms of heat-induced cell death and the way heating exerts its beneficial effect. It also discusses various heating devices as well as other modalities used with hyperthermia. The paper concludes with a summary of benefits and risks, obstacles encountered in the treatment process, and future research directions.

This study was driven by three underlying motivations. One of them is the gap between high penetration rate of mobile phone and relatively low adoption rate of m-commerce. The second is to reconcile the inconsistent findings in prior IT adoption research regarding the consistency of the relationship between attitude and intention. Finally, we hope to provide the theoretical underpinning for various interventions to promote m-commerce adoption. In this study, we extended the theory of planned behavior (TPB) by integrating confidence as a moderator for the relationship between attitude and intention. Furthermore, trial, communication and observation are identified as the sources for confidence with m-commerce and their effects are mediated through exposure. The research model was empirically tested and supported. Both theoretical and practical implications are discussed.

The location awareness of the primary user is one of the essential features of cognitive radios. The Location information of the primary user in cognitive radio can be used to assist the communication among secondary users outside the transmission coverage area of primary users or to track the primary users. A cognitive radio network based localization scheme is considered in this paper uses received signal strength (RSS) method to estimate the position and effective isotropic radiated powers of the transmitter source emitting this signal. In our investigation the simulation result for RSS-based localization show the impacts of number of sampling, nodes, sigma variable in the shadowing channel model on mean square error for position estimation and average power estimation error were illustrated. © 2011 IEEE.

The muscle force control of musculoskeletal humanoid system has been considered for years in motor control, biomechanics and robotics disciplines. In this paper, we consider the muscle force control as a problem of muscle coordination. We give a general muscle coordination method for mechanical systems driven by agonist and antagonist muscles. Specifically, the muscle force is computed by two steps. First, the initial muscle force is computed by pseudo-inverse. Here, the pseudo-inverse solution naturally satisfies the minimum total muscle force in the least squares sense. Second, the initial optimized muscle force is optimized by taking the optimization criteria of distributing muscle force in the middle of its output force range. The two steps provide an even-distributed muscle force. The proposed method is validated by a movement tracking of a bionic arm which has 5 degrees of freedom and 22 muscles. The force distribution property, tracking accuracy and efficiency are also tested. © Springer-Verlag 2013.

We describe a calculus that is specific to non-repudiation protocols. The calculus uses the correspondence assertion of Woo and Lam, that is, if there is a non-repudiation of receipt there should be a corresponding non-repudiation of origin. The calculus is a subset of the Pi calculus. The basic constructs are modified in order to handle properties of non-repudiation. We offer a formal syntax and an operational semantics of the calculus. We show the usefulness of the calculus by describing Zhou optimistic protocol.

A well-validated algorithm based on the finite element method (FEM) for determination of confined turbulent flow with a one equation model used to depict the turbulent viscosity is applied to a smooth straight channel. The overall effects of a zone close to a solid wall, "near wall zone" for predicting the distribution of the pertinent variables in this zone has been investigated. For the present work, a finite element technique based on near wall zone modeling has been advocated and the validation of the imposed technique has been examined and comparison with other techniques which has been made even with case of extension of the near wall zone. © 2012 IEEE.

In this paper, we investigate the effect of load size, geometry and properties on microwave heating efficiency and heating uniformity during microwave processing of materials using multi-mode cavity applicators. For this purpose, a numerical technique based on finite element method and implemented using COMSOL Multiphysics package is deployed to compute heating efficiency expressed in terms of power absorbed by the material divided by the input power. Both field variations and resulting temperature evolutions are computed for each size and shape studied. Results show that heating efficiency and temperature uniformity are dependent on the size, the geometry and the properties of the material to be treated and can be controlled to a large extent by just changing these material characteristics without the need of external impedance matching components. The model is experimentally validated and good agreement between the theoretical and experimental results is obtained. © 2016 International Microwave Power Institute

The interior design industry consumes significant amounts of natural resources, making designers morally obligated to the planet and its inhabitants. Designers must consider sustainable solutions to avoid the depletion of fragile ecological systems; they must employ different strategies to adjust all aspects of interior design to incorporate sustainable solutions, despite the many obstacles. This paper aims to explore the barriers preventing the implementation of sustainable design. This study focuses on sustainable practice within the context of interior design solutions.
