Spatial-reuse Time Division Multiple Access or STDMA is a MAC technique that allows simultaneous reception and simultaneous transmission of signals in a wireless network. Simultaneous transmission and reception between different antennas that are geographically very close impose various constraints on the power transmitted by these antennas. This report will delve into how to determine a feasib...

adequate nutrition is essential in early childhood to ensure healthy growth, proper organ formation and function, a strong immune system, and neurological and cognitive development. child malnutrition – as measured by poor child growth – is an important indicator for monitoring population nutritional status and health. in 2013, about 17%, or 98 million children under five years of age in develo...

Whether you just want to take a peek of a remote computer status, or you want to install the latest version of a software on several workstations, you can do all of this from your computer. The networks are growing, the time spent administering the workstations increases and the number of repetitive tasks is going sky high. But here comes MESH to take that load off your shoulders. And because o...

Dear Editor, In their interesting article on Collaboration and CoProduction of Knowledge in Healthcare,1 Rycroft-Malone and colleagues make the following point: “there are some general transferable qualities that might be embodied in researchers, such as being: able to wear more than one hat (being generalists), comfortable in the field, tolerant of messiness, a good communicator with different...

OF THE DISSERTATION Multi-hop Routing for Wireless Mesh Networks

Polygonal meshes are used in many application scenarios. Often the generated meshes are too complex not allowing proper interaction, visualization or transmission through a network. To tackle this problem, simplification methods can be used to generate less complex versions of those meshes. For this purpose many methods have been proposed in the literature and it is of paramount importance that...

We compare selected mesh generation methods from intensity data and binary segmentions with respect to their application to surgical planning and make recommendations on how to receive smooth and accurate surface meshes for exemplary cases. We consider especially local curvature, distances between two meshes (before and after processing) and volume preservation as measures. Sample data from the...

In this paper we present a coder for polygon mesh connectivity that delivers the best connectivity compression rates meshes reported so far. Our coder is an extension of the vertex-based coder for triangle mesh connectivity by Touma and Gotsman [26]. We code polygonal connectivity as a sequence of face and vertex degrees and exploit the correlation between them for mutual predictive compression...

child abuse is a recognized public health and social problem worldwide. according to the world health organization (who), child abuse includes all forms of physical and/or emotional ill-treatment, sexual abuse, neglect and negligent treatment and exploitation. child maltreatment is a global problem with serious life-long consequences. in spite of recent national surveys in several low- and midd...

An automatic adaptive quadrilateral mesh conversion scheme for the generation of adaptive refinement meshes over analytical curved surfaces is proposed. The starting point of the quadrilateral mesh generator is a background triangular mesh of the curved surface. By a carefully controlled process to merge two triangles at a time the triangular mesh can be completely converted to quadrilaterals. ...
