The huge amount of data need to be processed with algorithms such as beam forming, FFT, FIR, and more complex algorithm in the field of machine learning. Then the result is need to be displayed in a computer screen. One way to accomplish the data process system is to use the digital circuit gate-level parallel logic in FPGA to realize simple algorithms, and CPU to realize more complex algorithms. However, this kind of system has defects such as complicated hardware, low commonality, limited calculation ability in CPU. Therefore, a new kind of software system based on CUDA/OpenGL is designed, which needs simpler hardware as well as lower cost, and has more flexibility in use relative to the traditional system. Without any auxiliary hardware, tests show that the software system can present much higher efficiency in ultrasonic data process over the traditional way.","PeriodicalId":243839,"journal":{"name":"2016 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124155144","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 investigate the mass sensitivity of SAW sensors, which were fabricated based on Si/AlN structure by depositing aluminum oxide (AhO3) thin films on the active area between the input port and output port of the SAW devices. The material of the IDTs is aluminum. To validate the sample accommodation and protection function of the SiN thin film in bio-liquid detection processes, the contact angle of the SiN surface is also detected. We found that the mass sensitivity of the SAW devices is as high as 1958 MHz/g and the SiN surface is hydrophilic with contact angle of 45 degree. The research results indicate the AlN based SAW devices can be well employed in certain biosensing applications.","PeriodicalId":243839,"journal":{"name":"2016 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"35 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120871368","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 band gaps are calculated taking magneto-electro-elastic coupling into account. The influences of material and the filling fraction are discussed.

In this article, we use the radial cylindrical layered model to examine monopole logging response with a two-dimensional axisymmetric finite difference method. Three variables are set, that is, the transition zone thickness, the source frequency and source-receiver spacing, respectively. We also use the slowness-time correlation-method to evaluate sound speed variations under different conditions. At last, based on the ray theory, the variation characteristics of the arrival time of the first wave under different conditions are analyzed. We conclude that the radial detection characteristics of compression waves are greatly affected by spacing. By combining different signals with various spacings, it is possible to obtain the tomography of the compressional wave velocities near wellbore.","PeriodicalId":243839,"journal":{"name":"2016 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133865780","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 basic frequency of the horn is 16.86 KHz, and its input electrical power is 1 kW. It can operate continuously at 100 centigrade on the industrial scale. Firstly, according to the working environment, the modal of the ultrasonic horn was designed. Based on the equivalent circuit method and the transfer matrix method, the parameters of the horn were calculated. Secondly, the optimum operation mode and frequency were determined by modal analysis and harmonic response analysis using the FEM (finite element method) software ANSYS. At last, a prototype was made, and its basic frequency is in good agreement with the FEM simulation. The results show that this high-power ultrasonic horn can be applied on the industrial scale in viscosity reduction of heavy oil and ultrasonic sludge disintegration.","PeriodicalId":243839,"journal":{"name":"2016 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"47 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132398810","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}

Besides, the form of scattering wave is also deduced and the dynamic response is calculated and discussed.

There are four piezoelectric ceramic plates are bolted at the middle of the rod-shaped transducer and used to excite the stator's blending vibration mode. The ring is used to amplify the vibration amplitude of the rod-shaped transducer. The rotor pressed on the conical surface of the stator can be driven to rotate by the friction force induced by the traveling wave vibration of the stator. It can be seen from experimental results that proposed motor can rotate at the maximum value of 65 rpm and the maximum output torque is 0.07N•m, while applied with the driving voltage of 250 Vp-p.

The research using the transfer matrix method based on the nonlocal piezoelectricity continuum theory. The analytical expressions of the phase velocity equations of SH-waves propagation in the periodic layered piezoelectric structure with size effect are obtained for the case of wave propagation in the direction normal to the interface. The nonlocal effect has an obviously effect on the high frequency waves, but the effect on the lower frequency is not obvious, and the first band gap width can be decreased slightly when taking account of the nonlocal effect, and near the cut-off frequency, the bands are dense and flat, which imply that a strong wave localization phenomenon occurs. Furthermore, a cut-off frequency is found, beyond which the elastic waves cannot propagate through the periodic structure, and the size effect influence on the cut-off frequency and the wave propagation behavior are discussed.","PeriodicalId":243839,"journal":{"name":"2016 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114454621","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}
