<p>AbstractDifferent approaches for implementing a complex multiplier in pipelined FFT are considered andimplemented to find an efficient one in this project. The implemented design is synthesized on Cyclone IIand Stratix III to know the performance. The design is implemented with a focus of reducing the resourcesused. Some approaches resulted in the reduced number of DSP blocks and others resulted in reducednumber of LUTs. Analysis of Synthesis results is performed for different widths (bit lengths) of complexmultiplier approaches.</p>

This operations research thesis should be situated in the field of the power generation industry. The general objective of this work is to efficiently solve the Generalized Unit Commitment (GUC) problem by means of specialized software. The GUC problem generalizes the Unit Commitment (UC) problem by simultane-ously solving the associated Optimal Power Flow (OPF) problem. There are many approaches to solve the UC and OPF problems separately, but approaches to solve them jointly, i.e. to solve the GUC problem, are quite scarce. One of these GUC solving approaches is due to professors Batut and R

The dynamic characteristics of hydrogen and ionic bonding contributes to the reversible properties of acrylic polymers, opening new avenues for designing materials with mechanical strength and processability. These non-covalent interactions function as physical crosslinks, which provide enhanced structural and mechanical integrity to acrylic block copolymers. The strong hydrogen bonding or ionic interaction also directs self-assembly to hierarchical microstructures, which enables many applications including thermoplastic elastomers and energy storage devices.

The good performance achieved by this system indicates that higher throughput is possible while maintaining performance. An analytical bound for the performance of this system is presented.

In this paper, an idea of using space-time block coding (STBC) in multi-user cooperative diversity has been exploited to improve the performance of the transmission in wireless local area networks. The theoretical and simulation results show that, using STBC approaches can always achieve the better performance than existing techniques without introducing the space-time coding. By analyzing the throughput and frame error ratio (FER) of the two different STBC cooperative schemes, we find the trade-off between throughput and reliability.

However, some bits in the MBR representation are needed to track the basis information. The MBR image quality is deteriorated by discontinuities at block boundaries, as

Modern agriculture couples the management of invasive weed species with enhancing crop yields through the intensive use of herbicides. As a result of herbicides being the primary method of weed control in agronomic crops, herbicide resistance has evolved and there has been a vast increase in the occurrence and distribution of herbicide resistant weeds. Many of the most problematic weeds have now evolved multiple herbicide resistance (MHR), which is associated with an enhanced ability to detoxify xenobiotics, enabling the weed to survive herbicide application irrespective of the mode of action.

Cette thèse a commencé en novembre 2003 et présente la suite de travaux réalisés dans notre laboratoire (4 thèses déjà présentées). Le sujet de recherche de ces thèses est l'utilisation des filtres linéaires périodiquement variant dans le temps (LPTV) dans les communications analogiques et numériques. L'objectif de cette thèse consiste à appliquer les changements d'horloge périodiques (PCCs) à la conception des systèmes d'accès multiple. L'étude s'est focalisée sur une classe de PCCs : les entrelaceurs bloc (entrelaceurs matriciels, entrelaceurs circulaires et permutations aléatoires). Après u

Public sector reforms of recent decades in Europe have promoted managerialism and aimed at introducing private sector thinking and practices. However, with regard to public sector executives' self-understanding, managerial role identities have not replaced bureaucratic ones; rather, components from both paradigms have combined. In this article, we introduce a bi-dimensional approach (attitudes and practices) that allows for different combinations and forms of hybridity. Empirically, we explore the role identities of public sector executives across Europe, building on survey data from over 7,00

Modern agriculture manages competitive weed species through the intensive use of herbicides to ensure crop productivity. Resistance to aryloxyphenoxypropionate and sulphonylurea herbicides in the problem weed black-grass (Alopecurus myosuroides) is now a major problem in the United Kingdom, affecting approximately 80% of cropland. Increasing numbers of black-grass populations now exhibit multiple herbicide resistance (MHR), based on an enhanced expression of the biosystem responsible for herbicide detoxification termed the “Xenome”. The xenome is composed of cytochrome P450s (CYPs), glutathion

This work concentrates on the application of diversity techniques and space time block coding for future mobile wireless communications. The initial system analysis employs a space-time coded OFDM transmitter over a multipath Rayleigh channel, and a receiver which uses a selection combining diversity technique. The performance of this combined scenario is characterised in terms of the bit error rate and throughput. A novel four element QOSTBC scheme is introduced, it is created by reforming the detection matrix of the original QOSTBC scheme, for which an orthogonal channel matrix is derived.

碩士<br>國立臺灣科技大學<br>資訊管理系<br>91<br>Given six real video sequences, based on four new observations among the motion vector of the current block and the motion vectors of the eight neighboring blocks, this paper first presents a novel multiple--block--based search area prediction scheme. A sampling strategy with 4:1 sampling rate is used to realize the proposed multiple-block-based search area prediction scheme in order to compromise the tradeoff between the predicted accuracy and the required computation time. According to our proposed search area prediction scheme, this paper then pre

碩士<br>中原大學<br>電機工程研究所<br>91<br>The objective of the thesis is to present the block-based algorithm for multiple description image transmission. In this algorithm, the wavelet coefficients of the image to be delivered are partitioned into different groups including the low-pass and high-pass subbands. Then, the groups of high-pass subband are divided with block-based algorithm. The wavelet coefficients in each block and the group of low-pass subband are independently encoded using the set partitioning in hierarchical trees (SPIHT) technique. The decoders of the transmission system can reconstru
