However CSP has some shortcomings, particularly, it is sensitivity to noise and outlier data which results in lower classification accuracy. In this paper, we propose a regularized version of the original CSP (Corr-CSP), in which the objective function is penalized by a properly designed penalty term which encourages decorrelation between the data from two classes in such a way that the resulting objective function has still straightforward solution through Eigen value decomposition. Furthermore, we have used three different datasets from the BCI Competition BCI database in order to evaluate the performance of the proposed approach and compare it to the original CSP. The simulation results show on the average 4% of improvement in terms of classification accuracy for the proposed Corr-CSP approach.","PeriodicalId":6683,"journal":{"name":"2019 27th Iranian Conference on Electrical Engineering (ICEE)","volume":"92 1","pages":"1770-1774"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86232267","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}

However, their performance is exposed to failure due to high risk of short circuit (SC) fault. Although the output current of the resolver is negligible, its thin copper wires increases the probability of the short circuit fault. To avoid the propagation of the turn-to turn SC fault to the whole coil and undesirable performance of the motion control drive, it is necessary to diagnose it at the very beginning of its development. Meanwhile, the first step of diagnosing faults is their modeling. Time stepping finite element analysis is the most accurate, but computationally expensive method for modelling the electromagnetic devices. Therefore, it is required to establish an accurate, yet computationally fast model. In this regards, an analytical model based on d-q axes theory is proposed. Then, the success of the proposed model is validated by experimental tests on the studied sensor.","PeriodicalId":6683,"journal":{"name":"2019 27th Iranian Conference on Electrical Engineering (ICEE)","volume":"76 1","pages":"486-490"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91391797","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 order to have a wide frequency range and to keep the basic parameters of the PLL constant, a control unit is required. The proposed control circuit has two calibration sections; the first part is the frequency calibration, which determines the value of the digital code in the capacitor bank of the Voltage Controlled Oscillator (VCO), and the second part is the Charge Pump (CP), which measures the amount of the VCO gain (KVCO) and consequently changes the CP current flow to provide a fixed Bandwidth (BW). The main circuit of a PLL with an integer divider are implemented in a standard 0.18µm CMOS technology. This PLL, considering the time needed for calibration, is locked up within a period of 12.5µs. Phase noise ratio has been improved to the value of 1.3dBc/Hz by using the calibration circuit. The power consumption of the systems is 13.89mW at the supply voltage of 1.8V.","PeriodicalId":6683,"journal":{"name":"2019 27th Iranian Conference on Electrical Engineering (ICEE)","volume":"41 1","pages":"149-153"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91103166","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 fusion process is done in a patch-wise manner by adding the detail patches to the low resolution multispectral (LMS) patches. The detail patches are obtained from a sparse linear combination of the atoms (columns) of the detail dictionary which is constructed from the high-frequency information of the panchromatic (PAN) image. Therefore, the correlation coefficient between the PAN image and the ideal high resolution multispectral (HMS) image is considered as the injection gain of the details patches. To address the problem of unavailability of the ideal HMS image, an iterative algorithm is proposed which adaptively determines the injection gains. Also, the weights of constructing the intensity component, which is used to find the sparse coefficients of the detail patches, are optimally calculated using the least square error method. The simulation results of the Pleiades and GeoEye-l data demonstrate the superiority of the proposed method in comparison with the state-of-the-art methods in both visual and quantitative aspects.","PeriodicalId":6683,"journal":{"name":"2019 27th Iranian Conference on Electrical Engineering (ICEE)","volume":"44 1","pages":"1560-1565"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85129916","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}

Inspired by structure of blood vessel clogged partially by a blockage (e.g. due to atherosclerosis disease), a DMC system in a partially blocked biological cylinder is considered in this paper. Diffusive information molecules in the fluid medium are assumed to be exposed to biological receptors on the boundary, degradation reaction, and constant flow. The channel impulse response (CIR) for a point-to-point DMC system is numerically analyzed employing COMSOL Multiphysics tool as a finite-element solver. The impact of different system parameters on the CIR is examined. Our results reveal that the blockage significantly affects the CIR in the biological cylinder which may be employed by nanomachines for detection and characterization of the blockage in the blood vessels.","PeriodicalId":6683,"journal":{"name":"2019 27th Iranian Conference on Electrical Engineering (ICEE)","volume":"2016 1","pages":"1704-1709"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87780971","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}
