Factually, this polynomial has big number of terms, which makes it difficult to deal with in order to obtain useful information. For that reason, another technique, called the Reduction technique was introduced, for a simplified reliability polynomial. This technique transforms a complex network to its equivalent series and parallel form. Geometrically, a diffeomorphism has been used to change the initial reliability polynomial into a simplified form. Due to this original outcome, we formulate and prove some original results, regarding the “reliability”1 hypersurface for a given network model, and to find the critical points of the reliability polynomial, which proved the nontrivial compatibility of the system. In addition, we had analyzed and computed the Hessian Matrix of reliability polynomial, and try to algebraically interpret the manner in which the reliability polynomial had been convex or concave, which reveals that the reliability of the system is increased or decreased. Most of the calculations and figures made in this paper have used Mathematica software.1In the present work, the term “reliability” refers to extending of the standard definition of reliability; i.e. $mathrm {R}_{mathrm {i}}in (-infty, infty )$.","PeriodicalId":337384,"journal":{"name":"2017 Second Al-Sadiq International Conference on Multidisciplinary in IT and Communication Science and Applications (AIC-MITCSA)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122075890","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}

This paper introduces a two level secure colored image transmission system based on a recently proposed chaotic system, called Nahrain. In the first level, the chaotic system is used as a key for encrypting the secure color image. In the second level, the chaotic system is used as radio frequency carrier signal for modulating the digital data. The paper also proposes two new chaotic modulation methods, each method is designed with different testing types. The first method has seven types and based on single bit modulation. The second method has three types and based on two bits modulation. The nonlinear control laws are used to verify the synchronization of master-slave parts of the Nahrain Chaotic Map (NCM). The performance of the proposed methods is measured using Peak Signal to Noise Ratio (PSNR) and Bit Error Rate (BER) over Additive White Gaussian Noise (AWGN) channel. In comparison with Henon and Logistics chaotic systems, NCM showed better results when using Chaotic Shift Keying (CSK) Modulation. In this simulation, NCM achieved BER of $1.2787times 10^{-6}$ at SNR of 21dB, while the Henon and Logistic achieved 0.0124, and 0.0313 respectively. Furthermore, the results showed that the performance of the proposed single bit modulation methods over perform CSK where most of the testing types were error free at SNR equals 10 dB. Alternatively, the proposed two bit modulation methods can duplicate the transmission rate with few degradation in SNR does not exceed 2 dB at BER equals $10^{-4}$ as compared with single bit modulation methods.","PeriodicalId":337384,"journal":{"name":"2017 Second Al-Sadiq International Conference on Multidisciplinary in IT and Communication Science and Applications (AIC-MITCSA)","volume":"1997 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128225172","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}

It has emerged as an alternative to traditional forms of identification, like card IDs. Face recognition stands as the one of the most challenging modalities, since it is the natural mode of identification among humans. The Traditional FR methods that based on Visible Spectrum (VS) have facing challenges like pose variation, object illumination, facial disguises, and expression changes. Unfortunately these limitations degrade performance of Face Recognition. To overcome all these limitations, the Infrared Spectrum (IRS) is used in human FR, is chosen due to its inherent nature of being immune towards drastic ambient light changes. This paper presents the design and implement of Human face recognition system based on fusing three spectral images visual face images with near infrared image and thermal images to achieve feature integration in the recognition process and to improve final FR system performance. Gabor wavelet transform is used in feature extraction stage for extracting features. Support Vector Machine (SVM) is used in the classification stage. The proposed approach is tested on a Carl Face Database (Visual/ Near Infrared / Thermal) images. Experimental results show that our approach exhibits better detection accuracy for fusion of Multispectral Image (Visual/ Near Infrared / Thermal) than visual image. The maximum success of 96.4% recognition has been achieved.","PeriodicalId":337384,"journal":{"name":"2017 Second Al-Sadiq International Conference on Multidisciplinary in IT and Communication Science and Applications (AIC-MITCSA)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125214843","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}

A new scheme exhibited miniaturization more than 58 % compared to Euclidean microstrip loop resonator. A small patch was attached in one corner of a square loop resonator to degenerate dual mode configurations. On the other hand, a step impedance technique was utilized to tune the second band of the suggested BPF. Dual mode dual band responses are located at the medical applications (2.45 GHz) with -40 dB as a return loss and two transmission zeroes for sharp skirt response as a first band and also a tunable band from (4-5 GHz) for LTE applications with return loss less than -10 dB as a second band. To validate this structure design and analysis, CST computer simulation package was used. The dual mode simulation results have been extracted and compared with the literature which finding closed to each other. So that, CST simulator certified and can be adopted it for extracting a tunable dual-band results which have been achieved using a mentioned simulator.","PeriodicalId":337384,"journal":{"name":"2017 Second Al-Sadiq International Conference on Multidisciplinary in IT and Communication Science and Applications (AIC-MITCSA)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121447447","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}
