    Impact of Varying Channel Model Mixtures on Radio Resource Management for the OFDMA Downlink

    Adaptive resource allocation can drastically increase the throughput of an Orthogonal Frequency Division Multiple Access (OFDMA) system when the Channel State Information (CSI) is accurately known. Unfortunately, in practice, perfect CSI is rarely possible. In this paper, the authors study the efficiency of the OFDMA downlink for different vehicular user...

    Tracking 3D Human Pose With Large Root Node Uncertainty

    Representing articulated objects as a graphical model has gained much popularity in recent years; often the root node of the graph describes the global position and orientation of the object. In this paper a method is presented to robustly track 3D human pose by permitting greater uncertainty to be modeled...

    Using Visualization to Debug Visualization Software

    Developing visualization applications is non-trivial and poses special challenges. This is due to the fact that typical visualization software processes a large amount of data resulting in large and sometimes very complex data structures. Traditional tools for debugging are of limited use because they de-couple the information they report from...

    Do Powerful Chief Executives Influence The Financial Performance Of United Kingdom (UK) Publicly Listed Companies?

    Drawing a framework from the economics and power strands of organization theory this paper examines the relation between the decision-making power of Chief Executive Officers (CEOs) and the financial performance of 224 United Kingdom (UK) Publicly Listed Companies (PLCs) using panel data for 2003-2008. Overall, the authors' results do not...

    A Localization Scheme for Underwater Wireless Sensor Networks

    In this paper, we study the localization problem in large-scale Underwater Wireless Sensor Networks (UWSNs). Unlike in the terrestrial positioning, the Global Positioning System (GPS) can not work efficiently underwater. The limited bandwidth, the severely impaired channel and the cost of underwater equipment all makes the localization problem very challenging....

    The Historical Relation Between Savings, Investments, Exports, Domestic Consumption And Economic Growth In Sweden Between 1830 And 1970: An Exploratory Analysis

    In this paper, the authors examine the empirical relation between economic growth and financial intermediation in Sweden between 1830-1970, and also examine the effect on economic growth of exports, savings and investment and changes in private consumption over that period. The economic history literature advances three main arguments for the...

    What I Read About The Global Financial Crisis In 2007 And 2008

    Inspired by Eliot Weinberger's piece in the London Review of Books ('What I Heard about Iraq in 2005') and Walter Benjamin's 'Method' of montage the author traces the global financial crisis through selected quotes. The author follows a chronological approach, sometimes briefly fastforwarding to pursue a storyline. The quotes build...

    Wireless Mesh Networks

    Wireless telemedicine using GSM and GPRS technologies can only provide low bandwidth connections, which makes it difficult to transmit images and video. Satellite or 3G wireless transmission provides greater bandwidth, but the running costs are high. Wireless networks (WLANs) appear promising, since they can supply high bandwidth at low cost....

    Real Time Scientific Visualization of the ALE Based Free Surface Simulation for Virtual Reality Applications

    Free surface flows are found in many natural and manmade environments. Examples of natural occurrence include waves due to tsunami, flooding and interface between oil and gas. Examples of artificial environments are: Waves generated by ships, sluice gates and manufacturing applications such as metal casting. Modeling such waves normally forms...
