The key element of this architecture is a single transistor with 513 inputs. The system includes one pair of configurable shift registers, a comparator stage with hysteresis and an output stage. The correlator is designed for processing sequences of 256 bits and is validated for a technology process of 0.35μm. The novel proposed architecture is described here and its operation is validated using simulation tools. We discuss ways to resolve the problems of simulation generated by the use of the 513-input floating gate device. The architecture is proposed to operate at low voltage.","PeriodicalId":285783,"journal":{"name":"2015 12th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126773880","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 study, Tungsten (W) filament material was employed for decomposing the source gases in the reaction chamber. Effect of chamber pressure on the phase transition in silicon oxide (SiOx) has been studied by using X-Ray diffraction (XRD) and Raman spectroscopy techniques. A relationship between phase transition of thin film and Si-H bonding has been recognized and explained by using Fourier transform infrared (FTIR) spectroscopy. The samples deposited at low substrate temperature of 200°C, has shown photoluminescence spectra in the red region and emission of spectra has been found to be in correlation with the size of nc-Si and/or defects present in the thin film.","PeriodicalId":285783,"journal":{"name":"2015 12th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127515147","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 current work, a methodology involving novel iterative technique considering feed-forward neural networks (FNNs) is suggested to extract approximate solution for the second-order nonlinear PDEs with real constant coefficients (RCCs) taking into account initial and boundary conditions. This perspective is designed to grant good approximation on the basis of learning technique which is associated with quasi-Newton rule. The constructed FNN has the regularizing parameters (weights and biases), which can be utilized to make the error function minimal. The construction of the model leads to the satisfaction of the initial and boundary conditions along with the training of FNN which satisfies the PDEs. Numerical experiments with comparisons exhibits the superior behavior of this technique. We have displayed that the proposed algorithm is much more effective than the other numerical method that confers solutions with good universalization and high precision.","PeriodicalId":285783,"journal":{"name":"2015 12th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132313910","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}

First, the image regions of the single isolated crystals are segmented by combining three different techniques: thresholding, single nearest prototype classification and snakes. Then, the image positions of the vertices of each single isolated crystal region are determined by using the Hough Transformation. Finally, both the shortest linear edge and the longest diagonal of each single isolated crystal region are extracted by measuring and comparing distances between the found image positions of the single isolated crystal region vertices. Experimental results revealed an absolute length error of 4.18 percent and 2.32 percent of the extracted shortest linear edges and the extracted longest diagonals, respectively.","PeriodicalId":285783,"journal":{"name":"2015 12th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132773509","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}

Then, the trajectory of the torque and flux are predicted and evaluated to minimize the defined cost function, the AVSV that minimize the error is selected and applied in the next control cycle. With this control scheme is possible to obtain a fast dynamic performance similar to the conventional direct torque control, with the advantages of a constant switching frequency and a larger sample time. The control scheme is simulated using Matlab/Simulink to verify the performance under steady and dynamic operation.","PeriodicalId":285783,"journal":{"name":"2015 12th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125534449","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}

Intrinsic amorphous silicon (a-Si:H) films and P3HT:PCBM heterojunctions were investigated as absorbing layers. Solar cell performance was characterized by current-voltage measurements under AM1.5 illumination and spectral measurements in the range from hν = 1.5 to 3.5 eV. The stack structure with a-Si:H (absorbing layer)/PEDOT:PSS (p-layer) interface exhibited the highest short circuit current density (Jsc). The best open circuit voltage (Voc) as a large as 0.73 V was observed in the stack structure with a-Si:H/P3HT:PCBM heterojunction as absorbing layer.
