However, classical PF techniques suffer from particle degeneracy and sample impoverishment. This paper proposes a new scheme for joint state and parameter estimation, based on the sequential importance resampling (SIR) particle filter. First, a local search strategy is proposed as a resampling strategy to overcome particle impoverishment. Second, a switching multiple modes filter is adopted to handle sudden changes of parameters in the state evolution model due to faults, which cannot be processed by conventional PF that assumes gradual parameter variations over a long period. The proposed estimation method is applied to degradation and remaining useful life (RUL) prediction of dynamic systems, such as heat exchanger in the heating, ventilation and air conditioning (HVAC) systems. Both natural and transient degradations are evaluated, while parameters dominating the degradation models are assumed to change before and after transient decay. The developed method is evaluated using simulation data, and results demonstrate the effectiveness of proposed method in state estimation and degradation prediction in heat exchanger.","PeriodicalId":424006,"journal":{"name":"2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128731149","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 several applications such as proximity detection, multiple capacitances have to be measured simultaneously. This could involve multiple transmitter electrodes and a receiver electrode connected to the body whose proximity is to be detected. In order to excite the transmitter electrodes, a single sinusoidal source is multiplexed to each electrode one at a time, while capacitance measurements are made between the excited electrode and the receiver. This process is slow and limited by the switching speed of the multiplexer used and hence all the capacitances involved cannot be measured simultaneously. To address this issue, a simple multiple-frequency capacitive measurement scheme is proposed in this paper. Sinusoidal signals of unique frequencies are produced using a binary counter and used as excitation for the transmitter electrodes. The displacement current received by the receiver is converted to a voltage signal and fast Fourier transform is performed on it to extract the magnitudes of the frequency components corresponding to the excitation frequencies. Thus, all the capacitances involved can be measured simultaneously. A simulation study performed, showed that the proposed multiple frequency scheme has low cross-excitation sensitivity compared to the multiplexer based scheme. Finally, the proposed scheme was implemented on an ophthalmic anesthesia training system to detect the proximity of the needle to important structures of the eye model. Test results from a prototype developed show that the scheme is effective in detecting the needle proximity and touch to various ocular structures thus demonstrating its use for practical proximity detection purposes.","PeriodicalId":424006,"journal":{"name":"2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116498719","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}

These devices, in addition to their particular function, can provide useful context information about the user behavior. In this paper we propose an indoor localization technique that exploits the presence of commercially available devices in the GiraffPlus AAL environment. GiraffPlus is a EU funded project, running in several test sites across Europe, that combines social interaction and long-term monitoring to help people live independently. In this context, the proposed localization algorithm is able to provide the position information in terms of last room visited by the user improving considerably the reaction of a user's caregiver in emergency situations. This paper also aims at providing a performance characterization of the commercially available devices used in the GiraffPlus AAL environments. We prove that, in order to guarantee an high level of reliability, this kind of device show a considerable transmission delay that makes the localization process non-trivial.","PeriodicalId":424006,"journal":{"name":"2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128098712","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}
