Our service, called ERSMAC, is designed to allow the deployment of the IEEE 802.11b protocol in industrial environments characterized by high BER and fast time variation. ERSMAC uses a maximum likelihood estimate of the BER to solve for the optimal packet size that maximizes the success probability of transmissions while minimizing the overhead cost. ERSMAC also implements an adaptive forward error correction scheme using Reed-Solomon code such that every retransmission attempt has a higher probability of success than the previous attempt due to its association with a stronger RS code. Finally, we show, through simulations, that ERSMAC outperforms the original unmodified IEEE 802.11b protocol in terms of average throughput, average delay and efficiency","PeriodicalId":244878,"journal":{"name":"2005 IEEE Instrumentationand Measurement Technology Conference Proceedings","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126091062","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 scanner resolution is limited by the applied acoustic wavelength. Shorter wavelengths result in better scanning resolution and improved scattering characteristics of blood, but suffer an increasing attenuation in tissue, thereby reducing the useful interrogation depth. Such scanners are able to visualize superficial tissue up to a few centimeters deep depending on the particular wavelength and tissue properties. We present results shown as a 3D visualization of the volumetric flow velocity of pervaded tissue cuboid color-coded and we report on an in vivo experiment (human tissue).","PeriodicalId":244878,"journal":{"name":"2005 IEEE Instrumentationand Measurement Technology Conference Proceedings","volume":"71 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115638357","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 method uses radio frequency spectroscopy, and is a small scale version of what is intended to be used directly in the fuel containers arriving to the power plants. The advantages with the method are that it is fast and reliable, and it can be used for measuring mean value characteristics of large amounts of biofuel. Reflection characteristics for frequencies from 310 to 1300 MHz are simulated and measured for sawdust. The attenuation is evaluated in frequency and time domain. It is concluded that a calibration of the whole system is needed to compensate for disturbances in the test system. Both the surface and the bottom reflection are possible to detect in time domain. The simulated and measured attenuation in frequency domain have a similar periodic behavior up to around 800 MHz. Above 800 MHz the system is disturbed by the higher order modes","PeriodicalId":244878,"journal":{"name":"2005 IEEE Instrumentationand Measurement Technology Conference Proceedings","volume":"15 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116898876","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 signal generator, the two channels have completely identical hardware structures so that they generate two identical sequences of pseudo-random signals to simulate two signals obtained from the upstream and downstream sensors of a cross-correlator, respectively. Special control strategies both in hardware and software have been implemented in such a way that the control error of time delay between the two channels can be reduced to less than a microsecond. The shift frequency and sequence length of each signal channel and the time delay between the two channels can be adjusted in wide ranges to satisfy majority of practical requirements. The start/stop control of each channel of signal and adjustments of the above parameters are carried out by a microcontroller with a dedicated keyboard and an LED display. The instrument has been evaluated by using a digital storage oscilloscope (Tektronix TDS220). Results obtained show that the control precision of the time delay is better than 0.05% when the time delay is 1ms and over. Comparison with an E+H commercial noise signal generator and an MP noise generator shows that the error of the new generator is much smaller than those of the other two","PeriodicalId":244878,"journal":{"name":"2005 IEEE Instrumentationand Measurement Technology Conference Proceedings","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127074782","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}
