The extra dimension is used to sample the signal in space and treat each frequency independently. Two methods to calculate the weights for the desired array pattern have been compared. These are Spatial Response Variation Constraint Pattern Synthesis (SRVCPS) and Inverse Discrete Fourier Transform (IDFT). The SRVCPS method relies on optimizations. The Spatial Response Variation (SRV) is constrained to ensure wideband operation. The IDFT method applies inverse Fourier transformation to the desired pattern which produces the required weights. Methods are compared in terms of beamwidth, sidelobe level and processing speed.","PeriodicalId":125634,"journal":{"name":"2011 Saudi International Electronics, Communications and Photonics Conference (SIECPC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117272425","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 sensor consists of Aluminum plus shape paddle bridge resonator with two proof mass arms, driving electrodes, sensing electrode and silicon substrate. Working in a resonant condition, the sensor's vibration amplitude is converted into the sensing capacitance change, which reflects the outside magnetic flux-density. Based on the simulation, the key structure parameters are optimized and the resonant frequency is estimated. The results of the device are in accordance with the theoretical values of the designed model. The results indicate its sensitivity 0.252 pA/uT, when operating at 10% of critical damping. The sensitivity and resolution can be enhanced through vacuum packaging.","PeriodicalId":125634,"journal":{"name":"2011 Saudi International Electronics, Communications and Photonics Conference (SIECPC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121256374","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 470–862 MHz frequency band is currently allocating to several services such fixed wireless access (FWA). International telecommunication union-radio (ITU-R) sector has allocated sub-bands within 470–862 MHz for IMT-A system. This concurrent operation causes a destructive interference that influences the coexisting feasibility between IMT-A and this existing service, FWA. This paper addresses a timely and topical problem dealing with spectrum sharing and coexistence between an IMT-A systems and FWA service within 790–862 MHz. Co-channel and adjacent channel with an overlapping band and with or without guard band are intersystem interference scenarios investigated. The deterministic analysis is carried out by spectral emission mask (SEM) technique. Different significant factors such as channel bandwidths, propagation path lengths, and clutter loss which influence the feasibility of coexistence are examined. Feasible coexistence coordination procedures in terms of separation distance, frequency offset, and guard band are suggested.","PeriodicalId":125634,"journal":{"name":"2011 Saudi International Electronics, Communications and Photonics Conference (SIECPC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126966599","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 simulation results indicated that the laser under strong optical feedback induce CW, pulsation or chaos operation depending on the value of α-factor and optical feedback strength. At higher values of α-factor and under very strong optical feedback the pulsing operation associated with reasonable intensity noise level (as low as quantum noise level) and becomes more dominant. We expect that fiber-grating laser subjected to strong optical feedback exhibits much more stability under higher values of α-factor which, means that the laser is locked at the external cavity frequency and pulsing operation is optimum for operating fiber-grating lasers.","PeriodicalId":125634,"journal":{"name":"2011 Saudi International Electronics, Communications and Photonics Conference (SIECPC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115459967","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}

To reduce delay, DSS identifies nodes for different sleep/wake according to their traffic load at two levels: a) Nodes with different sleep/wake schedule requirement according to their different traffic load based on their topological importance in the network. b) Nodes with different sleep/wake schedule based on handling burst traffic in the proximity of event occurrence node. It then assign different active interval to the nodes, according to their variable traffic load requirement defined by node topological importance and by handling burst traffic in the proximity of event occurrence node. Using these heuristics DSS reduces end-to-end delay and minimize energy per packet by minimizing the congestion at nodes having heavy traffic load. Simulations are carried out to evaluate the performance of the proposed protocol, by comparing its performance with S-MAC and anycast protocols. Simulation results demonstrated that the proposed protocol has significantly reduced the end-to-end delay, as well as has improved average energy per packet.","PeriodicalId":125634,"journal":{"name":"2011 Saudi International Electronics, Communications and Photonics Conference (SIECPC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122635295","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}

Magnitude of electromagnetic field response is very low and cannot be able to detect the deep target. To detect deep target new aluminium curve antenna is designed by using computer simulation technology (CST) software. 3D scale modeling with and without hydrocarbon was done by Finite integration method (FIM). Straight and curve antenna comparison was done in a 3D scaled marine environment. It was investigated that new design gave 158% higher magnetic field strength than straight antenna. A scale tank with a scale factor of 2000 was built to test the new designed antenna. The series of experiments were done to evaluate the performance of new design antenna with and without the presence of oil in a scale model. Magnitude verses offset (MVO) was done with new design curve antenna with and without oil. The experimental data was recorded with new design antenna with and without oil placed left and right side of receivers (Rx−1, Rx−3) respectively. The magnitude of the EM waves of this new designed antenna increases up to 168% with hydrocarbon. Curve fitting method using MATLAB software was done to validate the MVO data of new designed antenna with and without oil. Correlation value with new design antenna also confirms the presence of oil in a scale model.","PeriodicalId":125634,"journal":{"name":"2011 Saudi International Electronics, Communications and Photonics Conference (SIECPC)","volume":"29 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122838635","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}
