It has the ability to detect bio-targets with refractive indices between 1.33 (water) and 1.5. As the refractive indices of sensitive holes change, a significant shift in the peak of transmission is observed. This structure consists of air holes in silicon slab with 0.48a thickness and 10 $a$ × 10a µm2 active area which has band gap and waveguide modes for TE polarization. Finite difference time domain (FDTD) and plane wave expansion (PWE) methods have been used for the analysis. We've used effective refractive index of silicon for 2D simulation. The simulation results yield a maximum sensitivity of 300 nm/RIU and a quality factor of 418. These results compared with previous experimental or simulated results show considerable improvements.","PeriodicalId":6683,"journal":{"name":"2019 27th Iranian Conference on Electrical Engineering (ICEE)","volume":"32 1","pages":"18-22"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83221834","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 converter employs two active switches with complement gate commands. In order to regulate the output voltage of the converter a robust and adaptive non-linear control approach is presented. In this case an adaptive sliding mode control (ASMC) method is applied for the converter output voltage regulation. The feedback control law is applied based on sliding condition realization. The proposed sliding mode control (SMC) method guarantees asymptotic stability as well as robustness against input voltage variation and load resistance uncertainty. In order to demonstrate the capability of the proposed controller, simulation results, obtained by PSIM software, are presented.","PeriodicalId":6683,"journal":{"name":"2019 27th Iranian Conference on Electrical Engineering (ICEE)","volume":"94 1","pages":"841-845"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83563033","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, using Ionic Polymer-Metal Composites (IPMCs), an active micromixer has been designed.

As known, there is an optimum frequency for each depth of defect. Finding the depth of an unknown defect requires us to find the optimal frequency. In conventional single frequency methods, the optimal frequency is obtained by applying a wide range of frequencies to the system separately and comparing the corresponding results in a time-consuming process. Conventional multi frequency inspections were introduced to obtain more information about test specimens. There are two ways to apply multiple excitation frequencies to the test sample. First way is to apply them sequentially to a single excitation coil which is still time consuming and the second method is to apply them simultaneously to multiple coils. In simultaneous excitation the testing time is shorter, but its processing of phase and amplitude signals is still challenging. We propose and examine the capability of the multi frequency eddy current (MFEC) method to detect the depth of hidden cracks in a shorter time period; using our HTS SQUID gradiometer-based system. The measurements are performed in a noisy environment, and a planar double-D shaped printed-circuit-board coil is used as the excitation coil. Comparing with the results of the consecutive single frequency excitation measurements, the obtained depths of the flaws using MFEC method was confirmed.","PeriodicalId":6683,"journal":{"name":"2019 27th Iranian Conference on Electrical Engineering (ICEE)","volume":"14 1","pages":"360-363"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87275599","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, the effects of leakage flux variation under inter-turn winding fault conditions are studied. To analyze the transformer behavior under inter-turn winding faults, a three-phase transformer with actual dimensions is modelled using time stepping finite element method (TSFEM). For experimental investigation of leakage flux, four search coils are installed on the HV windings of the transformer and the frequency spectrum of search coils are analyzed. Search coils signature analysis for various situations of inter-turn faults and transformer operation are extracted. The obtained results show that leakage flux analysis can be used as an attractive and reliable method for transformer inter-turn fault detection.","PeriodicalId":6683,"journal":{"name":"2019 27th Iranian Conference on Electrical Engineering (ICEE)","volume":"114 1","pages":"709-713"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88091388","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}

Nowadays, Speaker verification based on factor analysis and i-vector space has a great impact on the performance improvement of these systems. In this paper, a method is proposed for weighting the model and test vectors, which utilizes the statistical characteristics of target training vectors. The effect of the use of weighted vectors on the accuracy of scoring and the performance of the entire speaker verification system was evaluated for Mel-frequency cepstral coefficients (MFCC) and power-normalized cepstral coefficients (PNCC) feature vectors, and two scoring methods, i.e., the cosine distance and probabilistic linear discriminant analysis (PLDA).

The test results indicate that the use of proposed weighted vectors reduces the error rate of the speaker verification system significantly.","PeriodicalId":6683,"journal":{"name":"2019 27th Iranian Conference on Electrical Engineering (ICEE)","volume":"2 1","pages":"1647-1653"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77260722","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}

Using the network in these control systems induced new limitations, That the most important of those is bandwidth limit. Scheduling methods are the solution to handle this limitation in NCS. Although This concept has been developed and its algorithms have been extended in time-based NCS, these methods are not usable in event-based NCS; because in these systems, event scheduling requires the simultaneous design of the event-triggering rule and the control algorithm with respect of the bandwidth limit. In this paper, the above issue is examined and lead to a new co-design of control and scheduling.
