The high number of small samples that are provided by microplates burden difficulties when designing an inspection system with a single camera. The major concern is the perspective that is unique for every sample, and only a limited number of samples can be imaged in a favourable perspective, that is directly from below or above the sample. A way to overcome this problem is to use multiple cameras. This work presents the integration of an arbitrary number of cameras to support microplates of all types and densities. It provides a mapping framework to deliver the subimages to the inspection algorithms and includes a one-step registration procedure that uses a registration plate with microplate dimensions. Furthermore, an estimation of the system's mapping uncertainty is given.","PeriodicalId":387839,"journal":{"name":"2012 IEEE International Instrumentation and Measurement Technology Conference Proceedings","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126774891","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}

To review this, in this paper are shown the results of a study at “University: Instituto Tecnológico de Chihuahua” in which the quality of thirteen points of waters sources, used for around 5000 users, were analyzed using commercial equipment. The response of ion selective electrode was evaluated with data acquisition system and the smart sensor architecture to measure Fluride concentration it was defined and the compensation method was selected. Also the response time of smart sensor was evaluated and compared with the setting time. Using standard reference solutions of Fluoride was demonstrated that the smart sensor designed has better performance compared with commercial equipment in two different ranges from 1 to 50 ppm and from 1 to 200 ppm. This design procedure can be applied to design smart sensors to measure other water parameters with ion selective electrodes and to do in situ and continuous monitoring in public water supplies.","PeriodicalId":387839,"journal":{"name":"2012 IEEE International Instrumentation and Measurement Technology Conference Proceedings","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126978168","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 a typical mill under normal operating conditions, up to 30% of the disturbances in the pulping process can be explained by chip variations. In this paper, the statistical analysis of the refining processes of the mills data has demonstrated that the chip basic density stabilization could result in 3.4 - 6.4% of refining energy saving. The laboratory scale experiment and its mathematical model simulation has revealed refining energy saving is about 6.3% while the standard deviation of wood chip density reduced from 12 to 7 (kg/m3).

However, a camera will produce much data and consume much energy. Consequently, the cameras, deployed in a large area, would have no overlapping field of views (fovs). This leads to we cannot determine the person's position in unobserved area correctly, due to the person's unpredicted motion change, such as taking turns. Smart phone-based dead reckoning (DR) method is recently observed to be an alternative for filling these cameras' gaps to realize seamless tracking. Therefore, in this paper, we propose to accurately track a person in indoor environment by employing particle filtering, which fuses the absolute position results from cameras and the relative position results from the smart phone-based DR method. Experiment results demonstrate the performance of the proposed joint tracking system. As we expected, the dead reckoning's drawbacks such as accumulative errors and the unavailability of the initial position, are solved by the cameras. As well, the positions' estimations between the cameras are filled with the DR method.","PeriodicalId":387839,"journal":{"name":"2012 IEEE International Instrumentation and Measurement Technology Conference Proceedings","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114357468","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}

Many medical instruments have been well developed and deployed in medical institutes, but many of them are bulky and clumsy for daily recording of subjects' activity. A distributed multi-channel physiological data monitoring system was developed for integrating versatile sensor modules attached in different parts of body. The physiological signals are acquired and processed, and the raw or preprocessed data are then transmitted through wireless communications to a backend server and storage for long-term recording and study. Time synchronization is critical for data fusion and therefore more accurate state discrimination can be achieved. Ubiquitous data access is fundamental, so a smart mobile device in a virtual computing environment will help on this requirement.","PeriodicalId":387839,"journal":{"name":"2012 IEEE International Instrumentation and Measurement Technology Conference Proceedings","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116296542","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 OFDMA receivers, CFOs break the orthogonality among the subcarriers and cause interchannel interference (ICI) and multi-user interference, which are the key impairment factors in OFDMA systems. In the proposed method, we compensate the CFOs in frequency domain by using the property that multiplication in time domain is achieved equivalently by circular convolution in frequency domain. Furthermore, to reduce the computational operations, we adopt different length of convolution filter according to the magnitude of CFO. Accordingly, the proposed method has lower computational complexity compared to the conventional fixed length convolution method under the same performance.","PeriodicalId":387839,"journal":{"name":"2012 IEEE International Instrumentation and Measurement Technology Conference Proceedings","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124147539","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}
