During a broadcast route discovery, the intermediate forwarding nodes include their location and mobility information in the Route-Request messages. Upon failure of all the node-disjoint paths learnt from the latest route discovery, the destination runs the algorithm to determine the set of node-disjoint paths on a predicted global topology, constructed from the location and mobility information collected during the latest broadcast route discovery, and sends a sequence of Route-Reply messages on each of the predicted paths. If the source receives at least one Route-Reply message within certain time, it continues to send the data packets along the newly learnt node-disjoint paths. Otherwise, the source initiates another broadcast route discovery. Simulation results of LPBR-M along with the link-disjoint path based AOMDV and node-disjoint path based AODVM routing protocols indicate that LPBR-M incurs the longest time between successive broadcast route discoveries and a hop count close to that incurred by the minimum hop count based multi-path protocols.","PeriodicalId":356711,"journal":{"name":"2009 3rd International Conference on Signal Processing and Communication Systems","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122767349","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}

They also provide secure communication in hostile environments where Radio Frequency-based communication can be easily tapped into or jammed by a hostile agent. Mobile optical communication will thus provide a highly desirable system in such an environment, e.g., a battlefield. This paper presents the design and performance of a system for providing mobile voice communication that is based on optical links. The voice channel is created over two Field Programmable Gate Array (FPGA) development boards which allow parameters to be changed as needed. These parameters are chosen so that the voice channel emulates the G.711 ITU-T standard. Several configurations with different data rates can be obtained by varying the sampling rate and the number of bits representing each sample so as to optimize the transmission parameters from both fidelity and dynamic range perspectives. The Quality of the audio channel for each configuration is determined by measuring the Mean Opinion Score (MOS) using an Agilent Voice Quality Tester (VQT). Other parameters such as echo and delay are also measured.","PeriodicalId":356711,"journal":{"name":"2009 3rd International Conference on Signal Processing and Communication Systems","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121804674","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 patients in our study developed transient vocal cord dysfunction; however surgery and anesthesia can also cause permanent vocal cord paralysis, which is a significant clinical problem. Early detection is important to optimize the chance of repair, and to avoid complications associated with an impaired swallow. We have developed an algorithm to detect altered vocal cord function, which is based on Wavelet Packet Analysis (WPA) and Support Vector Machines (SVM). This method is compared to the Hoarseness Diagram method (HDm), which was reported as an objective voice quality evaluation approach and can be used for pathological voice discrimination. We believe that our algorithm is unique in that samples were obtained from the same patients before and after their surgery. Our experiments using voice signals recorded from subjects before and after the procedure show a high classification accuracy, whereas HDm fails in the detection of a hoarse voice.","PeriodicalId":356711,"journal":{"name":"2009 3rd International Conference on Signal Processing and Communication Systems","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114127527","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 writing stroke is recorded from an image sequence taken by a moving camera. The automatic speed adaptation capability developed in the motion detection system has enabled very robust writing stroke detection. As a result, the temporal stroke distortion due to irregular writing speed has been eliminated. Since both the direction and magnitude of motion is detected at each instant, the writing stroke is correctly reconstructed by integrating the results. For this reason, feature vector for each digit character was constructed by connecting feature distribution in each direction. As a result, handwriting gesture recognition is achieved by simple template matching. The system performance has been evaluated by digit-writing gesture recognition with irregular writing speed, different users, or cursive writing. Preliminary experiments on hand-writing Chinese character recognition have also been attempted and the potentiality of the algorithm for more complicated gesture patterns has been tested.","PeriodicalId":356711,"journal":{"name":"2009 3rd International Conference on Signal Processing and Communication Systems","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115535402","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}
