Abstract:

Discovery of semantic Web services is a heavyweight task when the number of Web services or the complexity of ontologies increases. In this paper, we present a new logical discovery framework based on semantic description of the capability of Web services and user goals using F-logic. Our framework tackles the scalability problem and improves discovery performance by adding two prefiltering stages to the discovery engine. The first stage is based on ontology comparison of user request and Web service categories. In the second stage, yet more Web services are eliminated based upon a decomposition and analysis of concept and instance attributes used in Web service capabilities and the requested capabilities of the client, resulting in a much smaller pool of Web services that need to be matched against the client request. Our prefiltering approach is evaluated using a new Web service repository, called WSMO-FL test collection. The recall rate of the filtering process is 100% by design, since no relevant Web services are ever eliminated by the two prefiltering stages, and experimental results show that the precision rate is more than 53%.

Abstract:

In the field of computer vision and more specifically multi-camera systems color correction is an important topic of discussion. The need for color-tone similarity among multiple images that are used to construct a single scene is self-evident. The strength and weaknesses of color- correction methods can be assessed by using metrics to measure structural and color-tone similarity and timing the methods. Color transfer has a better structural similarity than histogram-based prefiltering and a worse color-tone similarity. The color transfer method is faster than the histogram-based prefiltering. Color transfer is a better method if the focus is a structural similar image after correction, if better color-tone similarity at the cost of structural similarity is acceptable histogram-based prefiltering is a better choice. Color transfer is a faster method and is easier to run with a parallel computing approach then histogram-based prefiltering. Color transfer might therefore be a better pick for real-time applications. There is however more room to optimize an implementation of histogram-based prefiltering utilizing parallel computing.

Abstract:

A possibility for parametric signal estimation by Prony class methods is investigated in this work. So-called exponential-sinusoidal models are considered. These models comprise damped exponentials, damped and undamped sinusoidals, and various their additive combinations. Two main methods – the classical Prony method and Prony method with prefiltering – are studied in this work. The formulas for estimation of parameters of undamped and damped sinusoidals by the classical Prony method are derived. The algorithm for calculation of the impulse response of the filter used in Prony method with prefiltering is given. Software for estimation of exponential-sinusoidal models by Prony class methods is developed (in the MATLAB environment). Numerical experiments are carried out using the software developed. The conclusions on possibilities of application of the classical Prony method and Prony method with prefiltering are stated on the basis of simulation results.

Abstract:

碩士<br>國立交通大學<br>資訊科學與工程研究所<br>98<br>In recent years, optical proximity correction (OPC) technology has been widely used in semiconductor industry. Some software has been applied to simulate the exposure results for OPC photomask while other software has been used to check the (simulated) etched circuit for process constraints such as minimum spacing/width. These constraints are defined to avoid electrical failures such as bridge and pinch. This thesis research proposes an efficient algorithm to check the spacing of the OPC simulation results. The algorithm first applies a pre-filter to rapidly check minimum the spacing using low-resolution image. Sub-images for areas which may cause bridges are then restored with high resolution, through interpolation, to facilitate more precise examination of the spacing. Some preliminary experimental results show that the proposed system can provide required analyses satisfactorily in terms of accuracy and speed.

Abstract:

博士<br>國立臺灣科技大學<br>電子工程系<br>97<br>Most geographic information systems (GISs) use relational databases to manipulate information efficiently. They however suffer from interoperability issues because they need to expend significant effort mapping heterogeneous geographic information, which may have complicated structures, into relational data models, and vice versa. Geography Markup Language (GML) is regarded as a standard for expressing, storing, and exchanging geospatial data, and has been applied to help solve interoperability problems. Interestingly, no GIS has been built on native XML/GML technologies so far. There are two possible reasons for this: current XML processors are incapable of processing geospatial information, and they are inefficient in manipulating large XML documents. In this paper, we resolve these two difficulties and move forward to realizing GML-native Web-based geographic information systems. Specifically, we develop an XML/GML prefilter for enhancing query performance in the GML-native Web-based GISs as well as other generic XML processors. The prefilter is an efficient, small-scale, lightweight, minimal intrusive, and transparent technique for improving XML processing in large documents. The prefilter essentially uses a tiny search engine to locate interesting fragments in the source XML documents by approximately executing the user's queries. The interesting fragments and some necessary structural information are gathered into a candidate-set XML document that is returned to the XML applications for further processing. The prefilter can either reduce computational resources or lower query execution time. Depending on the nature of user queries, the enhanced query processors can reach ten-fold performance improvement, while an overhead of about 10~15% would incur for answering queries that return almost the entire documents.

Abstract:

碩士<br>國立成功大學<br>電腦與通信工程研究所<br>106<br>Combating inter-antenna interference (IAI) and inter-symbol interference (ISI) caused by multipath channels is a very important issue in single-carrier spatial modulation (SC-SM) systems. Although using linear equalizers achieves a low complexity, the bit–error-rate (BER) performance is far from optimal. The maximum likelihood detector (MLD) gives the optimal BER performance; however, the complexity increases exponentially with a larger constellation size or a longer data block length. Taking advantage of the block circulant characteristic of the channel in the SC-SM systems, the M-algorithm can be directly applied to reduce the complexity of the MLD. Due to the fading channels, however, this method needs to retain a large number of branches to maintain a good BER performance, which results in a high complexity in tree search. In the thesis, we propose to precede the M-algorithm with an appropriately designed frequency-domain prefilter to improve the equivalent channel, so that the number of branches retained by the M-algorithm (and thus the complexity of tree search) can be significantly reduced. Since the signal processing and design of the prefilter are done in the frequency domain, the complexity overhead incurred by prefiltering is relatively small. Simulation results demonstrate that compared to the conventional M-algorithm, the proposed algorithm achieves the same BER performance with a considerably lower complexity

Abstract:

Abstract Although systematic studies of non-linear time series modelling are fairly recent activities, non-linearity has been recognized for quite a considerable time. In the past, a popular approach was first to pass the data through a simple non-linear filter (e.g. a limiter; cf. the hard censoring device of §3.3.2) and then the filtered data could be modelled by a linear model. This is somewhat similar in spirit to the pre-whitening approach advocated by Tukey in the 1950s in spectral analysis (see e.g. Priestley 1981, p. 556). An early example of successful application of this prefiltering approach to non-linear time series modelling was in control engineering (see e.g. Otomo et al. 1972).
