This paper presents and analyses the general relation between such transforms and the 2-D LMS adaptive algorithm. It is shown that, by proper choice of the adaptation constant, the 2-D LMS provides an exact estimate to the forward as well as backward transform coefficients employing any set of 2-D DOT. The 2-D LMS DOT is modular and allows concurrent computation for the transform coefficients and therefore has the potential for fast parallel computations and VLSI implementation. An efficient 2-D threshold LMS DOT algorithm that is robust against impulsive noise is also presented. The efficiency of the 2-D LMS DOT against roundoff errors is demonstrated. Simulation experiments are conducted to justify the analysis and algorithms introduced.","PeriodicalId":379820,"journal":{"name":"2013 Second International Japan-Egypt Conference on Electronics, Communications and Computers (JEC-ECC)","volume":"304 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116268575","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}

Task replication is an established technique to achieve fault tolerance; however it has a negative influence on schedule length. Moreover increasing system reliability always has a negative impact on schedule length. In this paper we devised a new method for optimizing schedule length and maximizing system reliability simultaneously using simulated annealing. Schedule length is investigated in case of fault free operation and in the presence of a processor fault and then the schedule length is averaged based on the probability of the schedule success and failure, then this average schedule length is optimized to the minimum to give the lowest possible makespan in both cases. Results show that our algorithm is able to maximize the system reliability without degrading schedule length, in fact increasing system reliability decrease the averaged schedule length and hence the system overall performance in all cases.","PeriodicalId":379820,"journal":{"name":"2013 Second International Japan-Egypt Conference on Electronics, Communications and Computers (JEC-ECC)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124158966","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}

Closed-form expressions for the nonlinear electrostatic force due to any actuation electrode are obtained, and are used as exciting force for the mechanical part of the gyroscope, which is usually modeled as a set of mass-spring-damper systems representing each mode. Nonlinearity of detection electrodes as well as Brownian noise are modeled too. Numerical solution for the equations of motion was done using Simulink to verify the model. The evolution of vibration induced errors due to nonlinearity of actuation and detection electrodes is explained in details. The model helps quantify some important parameters and limitations for the ring gyroscope.","PeriodicalId":379820,"journal":{"name":"2013 Second International Japan-Egypt Conference on Electronics, Communications and Computers (JEC-ECC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124977974","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, several types of D/A converters employ resistors which consume a relatively large silicon area in addition to their poor tolerance. In this paper, an-all-NMOS-transistors D/A converter that depends on charging a capacitor to a voltage that is proportional to the decimal equivalent of the input bits is proposed. This technique can be extended to any number of input bits and will be simulated for the 0.13 μm CMOS technology with VDD = 1.2 V.

These heterogeneous types of numbers are forming a challenge in calculation the shortest path. In this work we propose a Unified Granular Number (UGN), that we call it G- Number to act as a general form for any uncertain granular number. G- Number represents higher level of abstract that hold only common properties of different types of uncertain granular numbers while ignoring some particular properties which are not necessary to be considered in such higher abstract level. The main benefit of using such a proposed G- number is the ability to represent all types of granular numbers using unified formality that greatly simplifies arithmetic operations.","PeriodicalId":379820,"journal":{"name":"2013 Second International Japan-Egypt Conference on Electronics, Communications and Computers (JEC-ECC)","volume":" 28","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113948820","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, this architecture consumes a relatively large silicon area. So, 1T-1C FRAMs are used instead. Reading 1T-1C FRAMs, however, requires generating a reference voltage that is ideally halfway between the bitline voltage generated in case of “0” reading, V0, and in case of “1” reading, V1. Then, this reference voltage will be compared with the bitline voltage by a sense amplifier. In this paper, a preview of some of the schemes that does not require generating a reference voltage will be introduced. Then, a novel reading scheme that does not require the generation of a reference voltage and depends on using two cascaded inverters is discussed. The proposed scheme will be simulated for the 0.13 μm CMOS technology and shows a 60% reduction in the read access time for stored “1”. The reduction in the read access time can be attributed to the fact that the output data will be taken at a parasitic capacitance that is much smaller than the bitline parasitic capacitance.","PeriodicalId":379820,"journal":{"name":"2013 Second International Japan-Egypt Conference on Electronics, Communications and Computers (JEC-ECC)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114541994","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 segmentation stage, connected component analysis is applied to find objects belong to license number. The objects will be analyzed to attach diacritic and over segmented objects to each other to form a group of recognizable objects. The final objects will be split to digits and letter groups. In recognition stage, an adapted template match technique is introduced to recognize the digits and letter groups separately after normalizing them.

The Wavelength Optical Crossbar (WOC), one of the important devices in optical networks, has been developed based on the phenomenon of wavelength exchanging. High-NonLinear Dispersion Shifted Fiber (HNL-DSF) provides a good performance due to the high mixing efficiency.
