Abstract:

<p>An electronic-hardware-based oscillogenic controller previously developed by P. K. Mercure was used as a model for translation into a software-based control algoritnm. The oscillogenic instrument, invented by P. R. Rony and P. K. Mercure, uses a feedback element (the oscillogenic controller) and a sensor component to produces a periodic signal yielding information about the instrument's sensor component. A control program that utilized the oscillogenic control algorithm was written in the Turbo Pascal programming language. An IBM PC with 640 kilobytes of read/write memory and with anal

Abstract:

Phylogenetics is the study of evolutionary relations between different organisms. Phylogenetic trees are the representations of these relations. Researchers have been working on finding fast and systematic approaches to reconstruct phylogenetic trees from observed data for over 40 years. It has been shown that, given a certain criterion to evaluate each tree, finding the best fitted phylogenetic trees among all possible trees is an NP-hard problem. In this study, we focus on the topology searching techniques for the maximum-parsimony and maximum-likelihood phylogeny inference. We proposed two

Abstract:

The goal of the Internet of Things’ sensing technology is to provide LBS(location-based services); a key technology is finding out how to positioning the sensing devices. For positioning outdoors, mature tech-nology such as GPS and cellular network location can be used. There is little research about indoor positioning, and there is no finished product on the market. This paper shows how to use both Wi-Fi and ZigBee signal for position-ing; Wi-Fi to find the area position and ZigBee to find the coordinate position.

<p> Global optimization problems sometimes attain their extrema on infinite subsets of the search space, forcing mathematically rigorous programs to require large amounts of data to describe these sets.

Abstract:

An increasing number of enterprises have the need of transferring data from a traditional database to a cloud-computing system. Big data in Teradata (a data warehouse) often needs to be transferred to Hadoop, a distributed system, for further computing and analysis. However, if data stored in Teradata is not synced with Hadoop, e.g. due to data loss during the communication, sync and copy process, it will cause the data to disaccord. A survey shows that except for the algorithm provided by Hadoop, the Bloom filter algorithm can be a good choice for data reconciliation. MD5 hash technology is a

Vocal tract morphology is an important factor in voice production. Its analysis has potential implications for educational matters as well as medical issues like voice therapy.

Abstract:

碩士<br>淡江大學<br>資訊管理學系碩士班<br>94<br>The research on the shortest path algorithm has quite a long history in computer science. It has also seen many applications in different fields such as intelligent transportation system (ITS), geographical information system (GIS) and robotics. Recently with the progress in technology, people began to use the electronic map in hand for path finding. To find the shortest path, precision, efficiency, and time are the three factors of concern. Under the premise of no pre-processing, traditional works focus on reduction of the search time by improving the heap dat

Abstract:

碩士<br>國立臺灣大學<br>電機工程學研究所<br>91<br>Deinterlacing is a scanning format conversion from interlaced picture to progressive picture. Multi-format digital broadcast and progressive display require the deinterlacing technology. Motion adaptive deinterlacing has been used widely in various kinds of commercial products but the picture quality is still not good at motion area. Motion compensated deinterlacing solves this problem by interpolation along the motion trajectory and has become the next generation technology for deinterlacing. However, it suffers visible artifacts caused by incorrect motion ve

The most important of all is to combine video technology with computers; many products such as video capture and TV box, etc, need to use video decoder. At the same time, video decoder can be used for video editing or even can be merged with digital communications. In the past, video decoding is achieved in analog way but in these days digital architecture is used for improving the quality of decoding and exten

However, some issues will be encountered for robot path planning such as long computation time, local optimal solution. So the mentioned approach can’t be applied on real-time path planning. A hybrid genetic algorithm is proposed for mobile robot path planning. A small amount of calculation in selection and crossover, use a small penalty factor, the majority of genes can contribute to the search. It

博士<br>元智大學<br>電機工程學系<br>106<br>Thinning algorithm has played an important role in digital image processing. Pattern reconstruction and shape preservation are the even more fundamental requirements of thinning algorithm. Both the widely used rule-based parallel thinning and distance-based medial axis transform have suffered from skeleton distortion. In a rule-based parallel thinning process, the increased iteration count caused by the incessant accumulation of the hidden deletable points (HDP) may give rise to skeleton distortion. Besides, the fork skeleton is split into more fork skeletons. Si

Iris biometric system has a high degree of stability and not easily copied or forged characteristic features, and does not require direct contact with user. It is a useful and highly secure biological characteristic in the biometrics identification. This paper presents an alternative and straightforward iris identification approach, which differs with the traditional approaches using transforma

Abstract:

General integer programming is an important mathematical approach for many decision-making problems. In this field, a major theoretical breakthrough came in 1983 when H. W. Lenstra, Jr. proposed a polynomial-time algorithm for general integer programs while the number of variables is fixed. Two key ingredients of Lenstra's algorithm are ellipsoidal approximation of polytopes and lattice basis reduction. However, the lack of practically efficient algorithms and software for the ellipsoidal approximation of polytopes has made it difficult to study the computational properties of Lenstra's algori

Because the executing times of GA are terrible when the scale of problem is large, it is necessary to distribute the computing jobs of GA with a distributed computing architecture. Apache Spark is one of the most efficient distributed computing architecture; however, there is still lack an efficient framework for integrating with GA and Apache Spark. For this research gap, this study proposes a novel architecture for highly integrating with
