The antennas were designed and fabricated on a substrate with dielectric constant of 4.4, thickness of 1.6 mm, and tan δ = 0.02. A novel Eagle shape uni-planar compact electromagnetic band gap (UCEBG) cells are applied to reduce the mutual coupling between array elements with the same shape. The results show that a reduction in mutual coupling of 6 dB is achieved at first band (1.71 - 2.98) GHz, 10 dB at second band (4.26 - 5.62) GHz, and 6 dB at third band (6.57 - 9.16) GHz. The microstrip array was studied by CST simulator and fabricated by proto laser machine with precision 25μm. The radiation patterns are measured in an anechoic chamber with Nearfield Systems Inc. (NSI) 700S-30 spherical near-field system. The antenna can be used in the military or wireless applications.","PeriodicalId":362288,"journal":{"name":"2016 Fourth International Japan-Egypt Conference on Electronics, Communications and Computers (JEC-ECC)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124756261","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 three major forms of parallelism on a modern processor are ILP, DLP, and TLP, which are not mutually exclusive. To gain further performance improvements, MPI can be used on a cluster of computers. This paper exploits the capabilities of distributed multi-core Intel processors for accelerating the well-known singular value decomposition (SVD) based on Jacobi's algorithm. On a cluster of Fujitsu Siemens CELSIUS R550 with quad-core Intel Xeon E5410 processor running at 2.33 GHz, hierarchical block Jacobi is implemented and evaluated. On eight nodes, our results show a performance of 184.56 double-precision GFLOPS by exploiting multi-threading, SIMD, and memory hierarchy techniques. Moreover, on large matrix size, the speedups of the hierarchical block Jacobi algorithm over sequential one-sided Jacobi improve from 17.33 using superscalar implementation to 30.46, 62.94, and 86.55, by exploiting the SIMD, multi-threading, and multi-threading SIMD techniques, respectively.","PeriodicalId":362288,"journal":{"name":"2016 Fourth International Japan-Egypt Conference on Electronics, Communications and Computers (JEC-ECC)","volume":"2000 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131334256","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 circuit overall dimension is (115 × 52 × 1.6) mm3 including the storage capacitor and operates over quad-band RF frequencies. Unlike the related works which use a separate antenna and a separate matching circuit per frequency band, we propose to use a single antenna and a single matching circuit that can operate over the different frequencies of interest. We design a single antenna that is optimized to simultaneously operate at 900 MHz, 1.8 GHz, 2.1 GHz, and 2.4 GHz with directivity of 2.119, 4.256, 4.436 and 4.028 dBi, respectively. The overall RF-to-DC conversion efficiency is 85.7% at -10 dBm, 52.3% at -15 dBm, and 23.8% at -20 dBm, respectively.

The embedding watermark is done by applying SVD on the reflectance component of the sub-band LL. The results of the proposed watermarking approach are compared with those of the other traditional approaches. Evaluation is based on visualization, Peak Signal-to-Noise Ratio of watermarked image (PSNR), Normalized Correlation of watermark after detection (NC).

The timing problem that occurs when combining the pulse-position modulation and the pulse-amplitude modulation has been resolved using the proposed technique by applying the AM modulation to the data signal and the clock signal. Using the proposed architecture, the reception of the pulse-position modulated bits will not be affected by the combining of the amplitude modulation and the number of the amplitude levels can be increased as many as possible. The PPM technique and the AM technique are combined in so as to increase the total number of the transmitted bits without affecting the transmitted data signal bandwidth. A 5 bits 4 GB/s PAM-PPM link has been designed and simulated in 130 nm CMOS technology using 800 MHz input clock signal. The simulation results indicate that combining PAM technique with PPM technique increases the number of transmitted bits per clock cycle of the data signal without altering the bandwidth.
