PS is based on matching a desired phonetic pattern over existing phonetic lattices, avoiding heavy computations of acoustic probabilities during the search. Since PS requires substantial acoustic and language resources (LR) for training acoustic models, there is a need for reducing model training costs to support new target languages. Particular cases of under-resourced languages pose even a greater challenge for PS as the available LR are not sufficient for acoustic model training. This study examines methods for keyword search in a new target language, using existing models of another source language in the lattice generation phase. We explore methodologies for learning cross-language phonetic mappings depending on the availability of data in the target language. We describe three approaches for creating phonetic-mappings: linguistic, acoustic, and statistic, introducing an efficient way for learning a robust statistical cross-language mapping. Our cross-language PS experiments showed that learning a good cross-language mapping can alleviate acoustic mismatches between languages, to significantly improve cross-language phonetic-search.","PeriodicalId":177385,"journal":{"name":"2012 IEEE 27th Convention of Electrical and Electronics Engineers in Israel","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121270370","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}

However the application of direct pressure, as in the treatment of an external hemorrhage, is not possible. Most common techniques to achieve vasoconstriction are through heat; yet heating causes irreversible destruction of organ tissues. Therefore, there is a need for a non-thermal based technology for hemorrhage control. The current research describes, for the first, an attempt to reduce the amount of bleeding in animal model liver injuries by using electrical pulses treatment (EPT). In the experiments, which were performed on 28 rats and 14 rabbits, a short (25μs and 50μs) EPT was applied to the treatment groups and the amount of bleeding was compared to the non-treatment (NT) groups. A reduction of 60%, 36% and 44% in blood volume, was found in the 25μs-rats, 50μs-rats and 25μs-rabbits EPT groups, respectively (P<;0.001). Also, it was found that the hemorrhage control was not caused by the mechanical pressure applied by the electrodes, and there was no evidence for thermal coagulation. Further research is needed to fully expose the potential of this treatment and the modality for hemorrhage control in civilian and military settings.","PeriodicalId":177385,"journal":{"name":"2012 IEEE 27th Convention of Electrical and Electronics Engineers in Israel","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121701035","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}

Inform. Theory, May 2000), the capacity of fading channels with imperfect channel-state information (CSI) can be lower-bounded by assuming a Gaussian channel input X, and by upper-bounding the conditional entropy h(XY, Ĥ), conditioned on the channel output Y and the CSI Ĥ, by the entropy of a Gaussian random variable with variance equal to the linear minimum mean-square error in estimating X from (Y, Ĥ). We demonstrate that, by using a rate-splitting approach, this lower bound can be sharpened: we show that by expressing the Gaussian input X as as the sum of two independent Gaussian variables X(1) and X(2), and by applying Medard's lower bound first to analyze the mutual information between X(1) and Y conditioned on Ĥ while treating X(2) as noise, and by applying the lower bound then to analyze the mutual information between X(2) and Y conditioned on (X(1), Ĥ), we obtain a lower bound on the capacity that is larger than Medard's lower bound.","PeriodicalId":177385,"journal":{"name":"2012 IEEE 27th Convention of Electrical and Electronics Engineers in Israel","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114696331","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}

When electromagnetic pulses are applied to a molten metal during its solidification, the Lorentz forces causes to pressure waves, which change the microstructure from columnar dendrites to globular grains. PMO has a great potential in precise controlling of the solidification microstructure. The current work presents the development and the construction of a high current short pulse generator, which was required for the PMO research. The sample configuration consists of the non conductive crucible with a molten metal, which is placed coaxially inside a solenoid coil. The pulse generator is able to introduce short pulses with current amplitude of kA order into the coil. The proposed generator is based on resonance LCL circuit structure using a high current SCR switch. The fundamental idea of the power system is to convert a low-power, long-time input into a high-power, short-time output. Using resonant LC topologies, the durable resonant capacitor charging process established firstly, drawing low current from the net. Afterward, high frequency, high amplitude capacitor discharging process provides the necessary current to the work coil. The calculations and simulations of the system parameters and operation are described and the results of the experimental system behavior are shown. The theoretical considerations and the test results were found to be closely resembled.","PeriodicalId":177385,"journal":{"name":"2012 IEEE 27th Convention of Electrical and Electronics Engineers in Israel","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130265063","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}
