Abstract:
Cognitive radios have been proposed as a new technology to counteract the spectrum scarcity issue and increase the spectral efficiency. In cognitive radios, the sparse assigned frequency bands are opened to secondary users, provided that interference induced on the primary licensees is negligible. Cognitive radios are established in two steps: the radios firstly sense the available frequency bands by detecting the presence of primary users and secondly communicate using the bands that have been identified as not in use by the primary users.<p><p>In this thesis we investigate how to improve the

Abstract:
The efficient use of radio spectrum depends upon frequency assignment within a telecommunications network. The solution space of the frequency assignment problem is best described by the acyclic orientations of the network. An acyclic orientation Ɵ of a graph (network) G is an orientation of the edges of the graph which does not create any directed cycles. We are primarily interested in how many ways this is possible for a given graph, which is the count of the number of acyclic orientations, a(G). This is just the evaluation of the chromatic polynomial of the graph χ(G; λ) at λ = -1. Calculat

Dynamic Spectrum Access allows wireless users to access a wide range of spectrum which increases a nodeâ s ability to communicate with its neighbors, and spectral efficiency through opportunistic access to licensed bands.

The objective of this research is to investigate the power-control problem and analyze the network capacity in cognitive radio (CR) networks. For CR users or Secondary users (SUs), two spectrum-access schemes exist: namely, spectrum underlay and spectrum overlay. Spectrum overlay improves the spectrum utilization by granting SUs the authority to sense and explore the unused spectrum bands provided by PUs. in this scheme, designing effective spectrum-sensing techniques in PHY layer is the major concern. Spectrum underlay permits Sus to share the same spectrum bands with PUS at the same time and

We present a serially concatenated coding scheme for partial response channels. The encoder consists of an outer irregular LDPC code and an inner matched spectrum trellis code. These codes are shown to offer considerable improvement over the i.i.d. capacity (> 1 dB) of the channel for low rates (approximately 0.1 bits per channel use). We also present a qualitative argument on the optimality of these codes for low rates. We also formulate a performance index for such codes to predict their performance for low rates.

Thus, risk-targeted ground motion with 1% probability collapse in 50 years is adopted on ASCE 7-10.

The majority of steel-framed buildings in the CEUS were designed without regard to seismic loads. Such frames possess limited seismic resistance, and may pose an unacceptable risk if a large earthquake were to occur in the region. A key ingredient of bu

Abstract:
The capacity spectrum method is a very popular tool in the performance based earthquake resistant design of structures. Though it involves nonlinear static analysis, it can be used to predict the dynamic behaviour of the building under earthquake load. Since the analysis is only static and not dynamic, it is very well suited for the design offices and low end computer terminals as opposed to dynamic analysis which is very resource consuming. There are several methods/variations of methods, to perform the nonlinear static analysis, popularly known as pushover analysis and convert it to capaci

The design procedure always is pure frame. But have many brick wall fill in frame after finished. Are both factor arcade and brick wall building to collapse? Hence this study use capacity spectrum and SCM3D program to proceed by static pushover analysis. After pushover analysis, we can obtain capacity curve of building and to decided performance point by demand spectrum curve and damping. The performance point is actual response of

The vertical distribution of seismic force and capacity spectrum method adopted during pushover analysis will lead to significant impacts on the seismic capacity assessment results of buildings structure. Therefore, in this dissertation an in-depth investigation has been carried out with respect to the seismic force distribution and capacity-spectrum method for seismic capacity assessment of buildings str

Abstract:
碩士<br>國立高雄第一科技大學<br>營建工程所<br>92<br>The capacity spectrum method to be adopted in Taiwan uses the capacity spectrum of a concrete structure and its deducted demand spectrum to come up with a performance point, so as to demonstrate the maximum displacement and evaluate the seismic resistance of the structure during earthquakes. First, based on the type of concrete structures and the seismic condition of construction sites, this study calculates and compares the minimum design seismic forces and relevant parameters under both the 2001 version seismic design codes and the latest revised draft cod
