An important aspect of the credibility of search results is regionality of Web pages. In this paper, we propose a system for helping users assess the credibility of search results by measuring and presenting the regionality of support to Web pages. We conceive two different types of measures for evaluating \"geographical social support\": the uniformity of support and the proximity of support. The uniformity of geographical support (US) indicates uniformity of geographic distribution of Web pages linking to a Web page. It is calculated by using the Kullback-Leibler (KL) divergence. The proximity of geographical support (PS) express how a page is supported by pages geographically located close to the page. We describe our implemented prototype system that shows the two measures for Web search results.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132142214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the general flat format hologram has a limited viewable area, we usually cannot see the other side of the reconstructed object. There are some holograms to solve this problem. A cylindrical-type hologram is well known as the 360-deg viewable hologram. There are two kinds of cylindrical holograms, a multiplex hologram and a laser reconstruction 360-deg hologram. Since the multiplex hologram consists of many 2-D pictures, the reconstructed image is not truly 3-D. In contrast, a laser reconstruction 360-deg hologram has a true 3-D effect. In our previous study, the computer-generated cylindrical hologram was realized as a Fresnel hologram. However, since the spatial resolution and pitch of the output device is not enough. Its panel size 14.5mm x 10.9mm, resolution 1,400 x 1,050pixel, pixel pitch 10.4μm of Liquid Crystal on Silicon use reduced to 1/12 and made a hologram. In this report, panel size 13.8mm x 7.56mm, resolution 1,920 x 1,080 pixel, pixel pitch 7μm of Liquid Crystal on Silicon use reduced to 1/16 and made a hologram. To scale up reconstructed image size, we calculated high resolution computer-generated cylindrical hologram. Then, we print these fringes with the improved output device. As a result, we obtain a good reconstructed image from a computer-generated cylindrical hologram.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125855790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The figure of F0 in relations to the period of cycles of sound waves is one branch of the rectangular hyperbola. Based on a few symmetry assumptions on the hyperbolic property, we achieve a generalized hyperbolic structure so as to aggressively manipulate F0 contours. The modeling proves an equivalent expression of the resonance mechanism capable for dealing with the interaction of tone and intonation. Also, it is language-independent because no language-dependent hypothesis is necessary. This paper describes two applications of the hyperbolic structures of F0 contours to prosodic information processing. One modulates the baseline F0 contours when fusing additional makeup information onto them without altering the underlying linguistic information. The other separates local rise/fall F0 movements and global scale component from observed F0 contours, both being useful for estimating dynamical F0 variation. Our experimental results are very positive.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129241283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper we present a software program, JSPad, for writing Japanese sign language (JSL) with SignWriting. SignWriting has a large set of visually iconic symbols that represent handshapes, movements, locations and facial expressions; it can take a lot of time to find and choose appropriate symbols from the set to compose signs, particularly for novice users of SignWriting. JSPad can generate SignWriting signs from JSL text written in the JJS notation, which is a gloss-based notation system we proposed. This facility allows users to write JSL sentences in SignWriting in shorter time.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132623728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have developed this method by using a complementary combination of 1) received signal strength indicators (RSSIs) and vibration data acquired from active RFID tags, and 2) human behavior detected from various types of sensors embedded in the environment. Regarding the former, we use a pattern recognition method to select a feature appeared in SSIs received by several radio frequency (RF) readers at different places and to classify them into a particular location. In our work, we regard the estimated location as the most probable location where the object is placed. As for the latter, we use the detected human behavior to support the estimation based on the analysis of RSSIs. Experiment results showed that the proposed method improved the estimation performance from about 50 to 95% compared with using only RSSIs to localize objects. Moreover, the results also suggested that we can estimate object location indoors without sensors for detecting human position. This indoor object localization method can contribute for constructing an indoor object management system that improves living comfort.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"34 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120852363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the context-aware service, function of overall system and quality of service are also required to be maintained by circulating context information in adequate quality. This scheme manages the context information based on relationship between quality of context and quality of service. This scheme can avoid degradation of available network bandwidth and computational resource caused by circulation of excessive context information. From the initial experimental results using a prototype system of a ubiquitous live streaming video service, we confirm the available network bandwidth and computational resource.

The ESSEM framework comprises two phases, offline and online phases. In the offline phase, we prepare an environment structure that is formed by multiple sets of hidden Markov models (HMMs). Each HMM set represents a particular speaker and speaking environment. In the online phase, ESSEM estimates a mapping function to transform the prepared environment structure to a set of HMMs for the unknown testing condition. In this study, we incorporate the soft margin estimation (SME) to increase the discriminative power of the environment structure in the offline stage and therefore enhance the overall ESSEM performance. We evaluated the performance on the Aurora-2 connected digit database. With the SME refined environment structure, ESSEM provides better performance than the original framework. By using our best online mapping function, ESSEM achieves a word error rate (WER) of 4.62%, corresponding to 14.60% relative WER reduction (from 5.41% to 4.62%) over the best baseline performance of 5.41% WER.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127139847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
