IP traffic connections are allocated network resources based on their priority, data rate or network utility, which guarantee in turn the degree of service availability-quality-of-recovery (QoR) — of these connections when a failure occurs in a network. Using a Markov chain process, a mathematical model is conceived to quantify service availability which can be supported by M : N protection scheme, namely 1 : N protection scheme in IP-over-WDM networks. This model is analytically evaluated in terms of service availability and service disruption rate performance metrics.","PeriodicalId":119104,"journal":{"name":"2011 IEEE GCC Conference and Exhibition (GCC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114973805","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 idea was to design and manufacture a small size and light weight glass climbing robot for cleaning purposes. The design consists of four active (scanning) type suction modules, two servo motors, two free wheels, a cleaning mechanism, and a programmable onboard microcontroller. Each of the suction modules includes a vacuum generator and a chamber mounted on the supporting frame for adhering to the surface. The innovation of the proposed project is in using a scanning type suction module which is based on aerodynamics principles to provide adhering force for the attachment to the glass surface.","PeriodicalId":119104,"journal":{"name":"2011 IEEE GCC Conference and Exhibition (GCC)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116969724","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 smooth control signal is important if the controller is to suppress torsional vibrations in drillstrings. This is mandatory to avoid placing the expensive top-drive under loads of oscillatory torque; maintaining its integrity and minimizing maintenance costs. A chattering free sliding-mode controller optimized using a Particle Swarm Optimization (PSO) routine is proposed to avoid bit sticking phenomena and in addition, provide a smooth control signal to the top drive system. In this work, a discontinuous lumped-parameter torsional model of four degrees of freedom is considered, and the bit-rock contact is taken to be a variation of the Stribeck friction together with the dry friction model.","PeriodicalId":119104,"journal":{"name":"2011 IEEE GCC Conference and Exhibition (GCC)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125867709","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}

Game Theory is used to simulate bidding behavior of Gencos and develop Nash equilibrium bidding strategies for Gencos in electricity markets. In the proposed methodology, competition is modeled as a bi-level problem with the upper level subproblem representing individual Gencos for maximizing their profits, and the lower level sub-problem representing the Independent System Operator (ISO), which minimizes consumer's payments. The simulation results show that Gencos yield less total revenue in expectation under pay-as-bid pricing than under uniform pricing.","PeriodicalId":119104,"journal":{"name":"2011 IEEE GCC Conference and Exhibition (GCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116442162","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 current transport system, especially in large urban centers, requires significant improvements to reduce the current levels of carbon emissions and traffic congestion.

Ferromagnet-semiconductor Schottky diodes are useful model devices that allow for understanding of basic physical and electronic processes in transport of spin-polarized electrons across the interface between a conventional ferromagnet (itself a natural reservoir of spins) and a spin hospitable semiconductor like galliumarsenide (GaAs), where spin-carrying electrons can be used for quantum information processing. This paper will introduce a model that explains experimentally observed voltage dependence of finite spin transfer efficiency, using Schottky tunneling contact, and drift-diffusion equations. In the same framework we present a rate-equation based explanation for voltage dependent spin relaxation of hot electrons, which has also been experimentally observed in spin light emitting diodes (spin-LEDs). Based on this model, we present device suggestions that are realizable within the modern semiconductor growth and nanoprocessing R&D sector.","PeriodicalId":119104,"journal":{"name":"2011 IEEE GCC Conference and Exhibition (GCC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114424772","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}

Therefore the improvement of the performance of these microscopes relies on fabricating extremely sharp tips with well defined shapes. Tips with an apex radius of a few nanometers are often characterized in the field ion microscope (FIM) or the field emission microscope (FEM), to estimate their sizes. However, these methods are only sufficient for characterizing the very end of the tip. Here we present a quantitative model that links the electric field, which is adequate to generate either FIM or FEM images at certain applied voltages, to the radius of the nanotip and to the radius of the tip base as well. This model introduces a more accurate method to estimate the overall tip shape over a relatively long range.","PeriodicalId":119104,"journal":{"name":"2011 IEEE GCC Conference and Exhibition (GCC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128575246","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}

Because of the input voltage is supplied by a PV module, several types of feedback configurations are studied in order to select the most suitable circuit configuration that corresponds to minimum output voltage fluctuations. The feedback signal is taken from either line or the load side. Four circuit configurations have been studied; auxiliary, modified auxiliary, cascade, and modified cascade circuits. PSIM and MATLAB platforms were used to simulate the behavior of these circuits. The simulation results and the conducted analysis states that modified auxiliary circuit present the optimized configuration for PV modules. The feedback control for this circuit compensates the output voltage fluctuation due to irradiation change and temperature effect on the PV cells. Design recommendations and suggestions are proposed for future work.","PeriodicalId":119104,"journal":{"name":"2011 IEEE GCC Conference and Exhibition (GCC)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129258583","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}

We Implement an all-integrated programmable 16×16 magnetic coil array chip with a die-size of 1.5×1.5mm2 designed in bulk CMOS 0.5μm 3M2P technology. The integrated design does not require any external magnetic source. It relies on the Hall effect generated by the smallest permissible vertical coil inductors (in this reported technology, the inductor's planar area is 6μm×6μm). The coil array is selectively and dynamically controlled. Each cell, composed of the coil and its logical control circuitry, can emit eight programmable magnetic field levels. All array components are tuned to work at 900MHz and incorporate highspeed serial row/column switching. The array can be used to manipulate a small, in the order of 6μm×6μm, single molecule or in collaborative manipulation of larger bio-material objects.","PeriodicalId":119104,"journal":{"name":"2011 IEEE GCC Conference and Exhibition (GCC)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124596731","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}
