The emphasis is on optimal the clusters and locations of clusters to maximize the multi-hop range along a line based on the glowworm swarm optimization (GSO). We build the CT model which can't be solved by conventional method, and solve it by using GSO algorithm to get the optimal result. In GSO algorithm, every mobile node was considered as a glowworm, and the intensity of signs was the intensity of luciferin. Firstly, the initial deployment of nodes is set randomly. Then, after calculating the value of the movement probability, the direction of movement is determined as well as the direction of movement under the constraint of outage probability in CT model. Finally, the deployment of cluster nodes is finished by iterations. Simulation results show that our improve GSO (IGSO) algorithm has such characteristics as high precision and time saving by comparing with traditional GSO and ant colony system (ACS) algorithm.","PeriodicalId":331484,"journal":{"name":"2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124995632","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 paper, we developed a wireless wearable system for quantifying and tracking fatigue. The system is based on the scientific electromyography kinesiology study, which shows the mean frequency of the surface electromyogram (sEMG) signal decreases with the increase of fatigue intensity. According to this clue, from the engineering viewpoint, we assume the decrease relation mentioned is a linear relation and use statistical analysis (including 10 male subjects and 7 female subjects) to prove this assumption. Besides, in order to accurately assess fatigue, fatigue level is defined. Based on the simplified linear model mentioned, the fatigue level can be calculated efficiently. Furthermore, by considering the fatigue process as a dynamic process, we track the fatigue level by “forgetting” the sEMG measurement history taken at a relatively long time ago. Finally, the performance of the developed fatigue tracking system is tested and verified by the experiment of holding self weight.","PeriodicalId":331484,"journal":{"name":"2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121261099","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}

Pharmaceutical chemicals are often produced by means of freeze-dryers with very good results, even though the slowness of drying process may increase the product cost. Increasing the shelf temperature accelerates the drying process, but can increase the risk of melting and damaging the product. This risk could be minimized by following the product temperature evolution during the drying step, by means of a noninvasive measuring system able to perform an in situ continuous monitoring. Actual sensors are too invasive to permit a reliable measurement and in addition their dimension does not allow to employ many sensors in a small volume. This paper describes the development of a new multi-sensor structure based on an array of thermocouples having nanometric thickness. The thermocouple array can be embedded into the glass wall of a test vial having all the other characteristics equal to the remaining batch thus providing meaningful and reliable results. Prototypes of the proposed thermocouple array have already been realized and tested making it possible to map the temperature at intervals of few millimeters, following the ice edge during lyophilization.","PeriodicalId":331484,"journal":{"name":"2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130574369","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}

A high energy output can be only reached by an appropriate harvester design taking the parameters of the available vibration into account. Very often ambient vibration sources have relative low frequencies and amplitudes. In this paper, a novel cylindrical electrodynamic resonant vibration converter is developed for low frequency and low amplitude. The design envisages a fixed coil to have a reliable connection to energy management electronic. For repulsion forces a magnetic spring is proposed to ovoid friction and aging effects of mechanical springs. This ensures a high reliability and compactness of the system. The design parameters have been optimized by finite element method modeling and by experiments. In order to validate the simulation results, an experimental setup for the converter is realized. An evaluation for the generated energy is also treated. The results show that the harvester is able to generate 470 mV for frequency excitation equal to 26 Hz and a low amplitude vibration equal to 1 mm. For the power output evaluation, the optimal load resistance is close to the coil resistance which is equal to 34 Ω and the converter is able to generate 0.72 mW.","PeriodicalId":331484,"journal":{"name":"2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122964244","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 sensor is composed by a strip of aluminum plate with two ultrasonic piezocomposite transducers bonded at the ends of the plate. The time reversal technique acts as a dispersion compensator of the guided waves propagating in the plate, allowing time recompression of the waves. When the plate is subjected to a longitudinal traction, a time reversal focusing is performed between the transducers in order to detect the change in the focus due to strain. The strain can be evaluated by measuring the change of the amplitude and shift in the time of flight, and comparing them with a reference signal obtained at zero strain state. In order to improve the systems sensitivity, 2-2 piezocomposite transducers designed to operate between 0.2 to 3.0 MHz are used. Experiments are conducted by applying strain up to 150 μ-strain. The results show an increase in sensitivity when compared with the results of the conventional mono-element transducer greater than 200%.

A functional polymer with Bis (2-ethylhexyl) phthalate (DEHP) template was immobilized on the sensing surface of the inter-digital (ID) capacitive sensor with sputtered gold sensing electrodes fabricated over a native layer of silicon dioxide on a single crystal silicon substrate. Various concentrations (10 to 200 ppm) of DEHP in deionized MilliQ water were exposed to the sensor surface functionalized with molecular imprinted polymer (MIP) in order to capture the analyte molecule, hence introducing molecular selectivity to the testing system. Impedance spectra were obtained using EIS in order to determine sample conductance for evaluation of phthalate concentration in the solution. Electrochemical Spectrum Analyzer algorithm was used to deduce equivalent circuit and equivalent component parameters from the experimentally obtained impedance spectra employing Randle's cell model curve fitting technique. Experimental results confirmed that the immobilization of the functional polymer on sensing surface introduces selectivity for phthalates in the sensing system.
