How to evaluate the performance of an electric power distribution system unambiguously and quantitatively is not easy. How to accurately measure the efficiency of it for a whole year, using real time hour-by-hour Locational Marginal Price data, is difficult. How to utilize distributed computing technology to accomplish these tasks with a timely fashion is challenging. This thesis addresses the issues mentioned above, by investigating feeder performance analysis of electric power distribution systems with distributed algorithm.

In this thesis, we conducted tests in order to determine how system load affected the speed of commonly used algorithms. The difficulty of obtaining these type of results theoretically due to a large number of factors that can affect performance motivated the use of simulation. An implementation was constructed that ran the sorting algorithms Mergesort, Quicksort and Radixsort while the system was put under different levels of stress. This stress was created by generating cache misses using the software stress-ng. The resulting completion times, as well as the cache activity was logged. The re

Adaptive filters are frequently employed in many applications, such as, system identification, adaptive echo cancellation (AEC), active noise control (ANC), adaptive beamforming, speech signal processing and other related problems, in which the statistic of the underlying signals is either unknown a priori, or slowly-varying. Given the observed signals under study, we shall consider, in this dissertation, the time-varying linear model with Gaussian or contaminated Gaussian (CG) noises. In particular, we focus on recursive local estimation and its applications in linear systems. We base our

In the design of material handling systems with complex and unpredictable dynamics, conventional search and optimization approaches that are based only on performance measures offer little guarantee of robustness. Using evidence from research into complex systems, the use of behavior-based optimization is proposed, which takes advantage of observed relationships between complexity and optimality with respect to both performance and robustness. Based on theoretical complexity measures, particularly algorithmic complexity, several simple complexity measures are created. The relationships betw

Experimental and observational data emerging from various scientific domains necessitate fast, accurate, and low-cost analysis of the data. While exploring the landscape of big data analytics, multiple challenges arise from three characteristics of big data: the volume, the variety, and the velocity. High volume and velocity of the data warrant a large amount of storage, memory, and compute power while a large variety of data demands cognition across domains.

This short note discusses performance bounds for "Ahrens" algorithm, that can generate random variates from continuous distributions with monotonically decreasing density. This rejection algorithms uses constant hat-functions and constant squeezes over many small intervals. The choice of these intervals is important. Ahrens has demonstrated that the equal area rule that uses strips of constant area leads to a very simple algorithm. We present bounds on the rejection constant of this algorithm depending only on the number of intervals. (author's abstract)<br>Series: Preprint Series / Department

Due to the energy limitations and the hardware constraints of sensor nodes, distributed transmit beamforming is considered as an attractive candidate for long-range communications in such scenarios as it can reduce energy requirement of each sensor node and extend the communicatio

A methodology for increasing the success rate in debt collection by matching individual call center agents with optimal debtors is developed. This methodology, called the trade algorithm, consists of the following steps. The trade algorithm first identifies groups of debtors for which agent performance varies. Based on these diﬀerences in performance, agents are put into clusters. An optimal call allocation for the clusters is then decided. Two methods to estimate the performance of an optimal call allocation are suggested. These methods are combined with Monte Carlo cross-validation and an al

In practical applications, some important classes of problems are NP-complete. Although no worst-case polynomial time algorithm exists for solving them, state-of-the-art algorithms can solve very large problem instances quickly, and algorithm performance varies significantly across instances. In addition, such algorithms are rather complex and have largely resisted theoretical average-case analysis. Empirical studies are often the only practical means for understanding algorithms’ behavior and for comparing their performance. My thesis focuses on two types of research questions. On the science

Furthermore, it is shown that by incorporating domain specific knowledge into a genetic algorithm near optimal solutions can be located in minimal time.

碩士<br>國立清華大學<br>資訊科學學系<br>81<br>In this paper, we propose a performance driven placement method for FPGAs. The proposed system first assigns the levels of the network using as-soon-as-possible method and finds the relative locations by a bipartite weighted matching algorithm. It then searches for the network shape to fit into the given FPGA architecture. Lastly, a bipartite-weighted-matching is performed again to assign cells into the new shape. Our method is able to produce a shorter criti

This is a second signal-detection analysis of the accuracy of a robot in detecting open access (OA) articles (by checking by hand how many of the articles the robot tagged OA were really OA, and vice versa). We found that the robot significantly overcodes for OA. In our Biology sample, 40% of identified OA was in fact OA. In our Sociology sample, only 18% of identified OA was in fact OA. Missed OA was lower: 12% in Biology and 14% in Sociology. The sources of the error are impossible to determine from the present data, since the algorithm did not capture URL's for documents ide

碩士<br>國立中興大學<br>資訊科學與工程學系所<br>107<br>The technological advancements on integrated circuits (IC) drive the increasing of wafer size as well as the number of dies that can be put in a wafer. As a result, the costs of testing and retesting wafers also increase. Wafer test is divided into probing and re-probing phases. Wafer probing phase is for checking the quality of each die in the wafer. Wafer re-probing phase only retests the failed dies discovered in the probing phase. To do chip probing on a wafer, the probes on the probe card need to make contact with wafer for electrical testing (In-Circu

碩士<br>國立清華大學<br>資訊工程學系<br>90<br>The World-Wide Web traffic keeps on growing rapidly. The web proxy is common solution to reduce the web traffic and the policy of the cache replacement plays a key factor to the performance of a web proxy. In the past, cache architecture has been extensively studied in many fields and several cache replacement algorithms for the web proxy have been developed. In the cache of web proxy, there are some phenomena that differ from those of other applications, such as computer architecture and operating systems. There are four different characteristics (1) size dist

碩士<br>國立中正大學<br>電機工程研究所<br>105<br>Image enhancement plays an important role in digital image processing and has been applied to fields of science and engineering. Among all of the image enhancement algorithms, Retinex-based algorithms are considered most effective in maintaining details of images. Despite the advantages, Retinex-based algorithms are generally more complex and consume considerably more time to maintain the balance between image detail and ambient illumination. And like most image enhancement algorithms, conventional Retinex-based algorithms are prone to over-enhancement when
