Abstract:
In the context of the Internet of Things (IoT), commissioning is the process of securely adding a new device to a network. It covers many different tasks, including the physical deployment of devices and configuration of parameters. It is network installers who need to manually commission each device one by one with the help of commissioning tools. In practice, the first task for a network installer is to identify each device correctly before configuring it with proper parameters. Individually identifying each device, especially in a large network, is a very time-consuming process. This is als

Abstract:
This thesis work will investigate and implement a method for reconstructing an unstructured mesh sequence with evolving topology. The goal of the method is to increase frame-to-frame coherency of the triangulation. The motivation of the method is that many of current state-of-the-art mesh compression and decimation algorithms for mesh sequences are based on static connectivity.

Abstract:
<p>Network on Chip is a scalable and flexible communication infrastructure for the design of core based System on Chip. Communication performance of a NoC depends heavily on the routing algorithm. Deterministic and adaptive distributed routing algorithms have been advocated in all the current NoC architectural proposals. In this thesis we make a case for the use of source routing for NoCs, especially for regular topologies like mesh. The advantages of source routing include in-order packet delivery; faster and simpler router design; and possibility of mixing non-minimal paths in a mainly minim

Robot motion can be described in several alternative representations, including joint configuration or end-effector spaces. These representations are often used for manipulation or navigation tasks but they are not suitable for tasks that involve close interaction with the environment. In these scenarios, collisions and relative poses of the robot and its surroundings create a complex planning space. To deal with this complexity, we exploit several representations that capture the state of the interaction, rather than the state of the robot. Borrowing notions of topology invariances and homoto

Three-dimensional scans and other volumetric data sources often result in representations that are more complex topologically than the original model. The extraneous critical points, handles, and components are called topological noise. Many algorithms in computer graphics require simple topology in order to work optimally, including texture mapping, surface parameterization, flows on surfaces, and conformal mappings. The topological noise disrupts these procedures by requiring each small handle to be dealt with individually. Furthermore, topological descriptions of volumetric data are usefu

Scalar fields occur quite commonly in several application areas in both static and time-dependent forms.

This is done by isolating these features and visualizing them independently or show all similar patterns that arise from a given search pattern.

Our algorithm consists of two phases. In the first phase, certain number of feasible solutions is generated. Firstly, a sweep heuristic is used to partition the whole network into some clusters

Abstract:
M. Tech. Electrical Engineering..<br>Wireless mesh networks (WMNs) have become a better alternative for extending wireless Local Area Networks (WLANs) to provide network coverage up to the furthest of far flung rural areas. This has been implemented by using a meshed backbone network interconnecting the mesh access points (MAPs) that manage each of the WLANs, thus providing a vital mode complimentary to the wireless infrastructure-based networks. The benefits of WMN deployments, however, come with certain challenges e.g., power management. Due to the limited availability of power in typical ru

碩士<br>國立臺灣大學<br>資訊網路與多媒體研究所<br>95<br>The performance of wireless network is significantly influenced by radio signal co-channel interference. In this paper, we address the issue of configuring a given set of wireless nodes so that co-channel interference within this network is minimized. The issue of interference is very important, especially in the case where a wireless node may have multiple network interference cards, and each of these interface can operate on difference channels. We divide the task into two stages topology control and interference control. The topology configuration is

碩士<br>國立交通大學<br>資訊工程系<br>87<br>Under the real-time rendering requirement of Virtual Reality applications, several types of accelerating techniques have been proposed to speed up the rendering process. Techniques of multi-resolution modeling are applied to reduce the geometry complexity in such a way that distant objects take coarsen level of detail while near objects take more detailed geometry. In the thesis, we propose a new mesh simplification algorithm that preserves the geometric and material appearance of a given mesh and modifies the topology to obtain a lower reduction rate.

Abstract:
碩士<br>中華大學<br>電機工程學系<br>106<br>A Hybird Mesh-Ring (HMR) algorithm is proposed for Bluetooth sensor networks. The algorithm is designed in three stages to determine the optimal configuration of the mesh-ring network. Firstly, a designated root advertises and discovers its neighboring nodes. Secondly, a scatternet criterion is built to compute the minimum number of piconets and distributes the connection information for piconet and scatternet. Finally, a peak-search method is designed to determine the optimal mesh-ring configuration for various sizes of networks. To minimum the path length, the

Power reduction issue for the clock network becomes an active research area since a large portion of power is dissipated on clock networks. Clock gating is an eective power reduction technique in sequential circuits. In this work, we propose a fast topology generation algorithm that feeds to zero-skew gated clock network construction. It considers the physical locations, input capacitances, and activity patterns of clock sinks in topology generation stage. Therefore, our algorithm generat
