This paper introduces the concept of Consolidated Demand Reduction Bid (CDRB) and develops a dynamic algorithm to compute the same for a consumer having a set of devices with different ratings, importance and constraints. CDRB consist of various power levels at which consumer is willing to curtail it's load during a particular control interval Pl(k) and the corresponding bid to curtail Pl(k) units of power for a specified duration is F(CPl(k)). The proposed algorithm can be implemented using two way communication between the consumer and the service provider. The applicability of the dynamic algorithm is illustrated using a cases study. The dynamic nature of the algorithm is also illustrated for different choices of the service provider.","PeriodicalId":127217,"journal":{"name":"2015 IEEE 8th GCC Conference & Exhibition","volume":"344 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122644846","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}

Towards that goal, in this paper we present an extensive study consisting of 18 experimental subjects controlling a simulated robot, using either no feedback or auditory feedback. Multiple observables were recorded, including not only joystick and robot angles and timings, but also subjective measures of difficulty, personality and usability data, and automated analysis of facial expressions and blink rate of the subjects. Our initial results indicate that: First, that the subjective difficulty of teleoperation with auditory feedback has smaller variance as compared to teleoperation without feedback, and second, that the subjective difficulty of a task is linearly related with the logarithm of task completion time. We conclude with a forward-looking discussion including future steps.","PeriodicalId":127217,"journal":{"name":"2015 IEEE 8th GCC Conference & Exhibition","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129691637","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}

From its inception, ECE accommodated the largest share of students in the college and was usually favored by students compared to other departments. Nevertheless, it was observed that students refrain from selecting ECE as a first choice in the last couple of years. In 2005, 33% of students applying for specialization chose ECE as their first choice. Today, the number is south to 13%.

The inverter is modulated with space vector PWM. However, the proposed approach is independent of the modulation technique. The open-circuit faults under study are single transistor open-circuit, single inverter switch open-circuit, double-transistors open-circuit, double-switches open-circuit, and inverter leg/legs open-circuit. The proposed approach is based on measuring the terminal voltages of the inverter and compares it with the output voltages of the analytical model. These measurements require one cycle from the output voltage to detect the fault and to identify the fault location. Simulation and experimental results of common open-circuit faults occurred in the five-phase voltage source inverter are given. Results and analysis lead to extract rules for different fault conditions. These rules help for both fault detection and localization.","PeriodicalId":127217,"journal":{"name":"2015 IEEE 8th GCC Conference & Exhibition","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126693287","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}

Oman Electricity Transmission Company and Tractebel Engineering analyze the challenges and review the existing load demand forecast studies used in Oman. Different studies analyze load forecasting at short to medium term. A spatialization of the long term load forecast is required in the Transmission Master Plan (2014-2030) of Oman in order to correctly address the transmission expansion plan. Several approaches are proposed to review and challenge existing studies and to spatialize the load demand forecast. The approaches are called global and areabased forecasting methods. Each approach is complimentary and allows to cross-check the adequacy of the method to the peculiarities of the local load demand and the accuracy of the data available. The global method allows linking the electricity consumption to the various economic indicators through mathematical regression relating the electrical energy consumption to socio-economic indicators. The area-based based method aims to spatialize the load forecast taking into account the consumption at regional level and the local characteristics of each area in the Sultanate. The results of the load demand forecast analysis defined the area with very high growth, the amount of generation required in the firm of the Transmission Master Plan and accordingly the least cost transmission network development plan.","PeriodicalId":127217,"journal":{"name":"2015 IEEE 8th GCC Conference & Exhibition","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125811220","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 this connection-oriented protocol, network failures can cause a serious disruption to critical data traffic which is unacceptable for customers who require highly reliable services. To guarantee high QoS and enhance network performance during failures, researchers have developed different recovery mechanisms for MPLS to ensure rerouting traffic from original faulty paths to alternate paths. In this paper, a comprehensive study is carried out on MPLS recovery mechanisms for protecting and restoring traffic after failure occurrence. In order to model the recovery mechanisms in MPLS networks, a new modeling framework for MPLS recovery was developed on a multi-layer approach. The new framework was designed to be generic and flexible in order to easily model network topologies with different MPLS recovery mechanisms and simulate variable parameters/scenarios for performance analysis purposes.","PeriodicalId":127217,"journal":{"name":"2015 IEEE 8th GCC Conference & Exhibition","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123983847","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}

As a result, electrical voltage is induced in other electrodes. The measured voltage across driver and non-driver electrodes/segments are called the piezoelectric voltage and the induced voltage respectively. The induced voltage has been used in displacement estimation and control of piezoelectric tube actuators since 2006, while the piezoelectric voltage has been used for the same purpose since 1980's. However, the newly introduced signal of the induced voltage has never been critically assessed for piezoelectric tubes' displacement estimation and control purposes, particularly in comparison with the piezoelectric voltage, another easy to measure electrical signal; this article aims to present such an assessment. In this research, both signals were mapped into displacement through linear and nonlinear models. It was shown displacement can be estimated less accurately via the induced voltage compared to the piezoelectric voltage and the relationship of displacement with the induced voltage presents higher nonlinearity compared to one with the piezoelectric voltage.","PeriodicalId":127217,"journal":{"name":"2015 IEEE 8th GCC Conference & Exhibition","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126354351","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 is found that the constantgain output injection is sufficient to make the observer globally convergent under the condition that all the system parameters are known. In addition, if the persistent excitation condition is verified, the time-varying output injection is easily conceived by appropriate selection of a free design parameter. The observer design methodology is stated as the solution of a linear matrix inequality which is numerically tractable.
