The analysis takes into account the fact that the most suitable sites for installation of wind farms are located mainly in Southern Italy and that the power flows from wind turbines will arise in addition to the existing ones, mainly directed to Central Italy, thus increasing the possibility of network congestions. By means of a procedure of Optimal Power Flow the analysis determines any limitations to the full exploitation of wind generation capacity because of the constraints imposed by the transmission system, especially if not properly reinforced. Moreover, a sensitivity analysis, based on the nodal index Weighted Transmission Loading Relief (WTLR), assesses the impact of wind farms' generation on power system security. In any case the analysis aims at highlighting the need to complete the development plan of the Italian transmission system.","PeriodicalId":256057,"journal":{"name":"Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126417654","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 original electromechanical system, incorporating an intermediate energy storage located in a spring, is based on harnessing the energy from movement. We have built an electromechanical model using the Matlab Simulink application and proceeded with its experimental validation on various movement profiles. Our research has highlighted the existence of an optimal transfer of energy (obtained by either influencing generator design or regulating output voltage of the active rectifier connected to the generator) that helps maximize energy recovery. Finally, this paper presents the results of a system resizing study for the purpose of studying potential system productivity at other scales, and highlights the existence of an optimal set of parameters maximizing energy recovery.","PeriodicalId":256057,"journal":{"name":"Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121287093","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}

Moreover, the advent of new services such as Voice over IP (VoIP), Video on Demand (VOD) and Videoconferencing applications have caused a sever increase in traffic, which makes it extremely hard to ensure an acceptable level of quality. This is mainly attributed to current routing strategies, such as Link State (LS) and Distance Vector (DV), which are not optimal in terms of Quality of Service (QoS). This paper presents a QoS-Aware routing strategy based on the Ant Colony Optimization (ACO) concept, where a set of artificial ants are used to determine the optimal path. The proposed method was compared to other state of the art ACO procedures and traditional routing schemes like LS and DV. Simulation results clearly demonstrate that the proposed scheme outperforms all the methods considered in this paper where throughput gains of 8% and a reduction in delay of 38% for time critical applications were achieved.","PeriodicalId":256057,"journal":{"name":"Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121296544","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}

Ancillary services (AS) represent a good negotiation opportunity that must be considered by market players. Based on the ancillary services forecasting, market participants can use strategic bidding for day-ahead ancillary services markets. For this reason, ancillary services market simulation is being included in MASCEM, a multi-agent based electricity market simulator that can be used by market players to test and enhance their bidding strategies. The paper presents the methodology used to undertake ancillary services forecasting, based on an Artificial Neural Network (ANN) approach. ANNs are used to day-ahead prediction of non-spinning reserve (NS), regulation-up (RU), and regulation down (RD). Spinning reserve (SR) is mentioned as past work for comparative analysis. A case study based on California ISO (CAISO) data is included; the forecasted results are presented and compared with CAISO published forecast.","PeriodicalId":256057,"journal":{"name":"Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference","volume":"324 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122989359","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}

For dimension reduction, Principal Component Analysis (PCA) and for determination of gender, Fisher Linear Discriminant (FLD) algorithms were applied to masked face images. Moreover, the effects of racial features on gender classification were studied. Experimental results indicated that the nose is the most influential part for gender classification.

The time resolution is 1.89ps, and DNL of 0.9 and INL of 1.0 are achieved in simulation. To amplify the time residue of the first stage, the 16x cascaded time difference amplifier(TDA) using differential logic delay cells is employed. By using differential logic cells for the delay chain instead of CMOS logic cells, the 16x cascaded TDA realizes stable time difference gain(TD gain) and fine time resolution. The TDA have been fabricated in 0.18um CMOS process. Measurement results show that our TDA achieves 4.4% TD gain offset at 30ps input range, the standard deviation and the maximum error of the difference between the ideal amplified value and measured value is 13.0ps and 30.0ps respectively. The maximum error corresponds to 0.99 LSB. Linearity of the two stage TDC depends on the specifications of a TDA greatly. The linearity of the proposed TDC improved by using the 16x cascaded TDA and using only one TDA in the two stage TDC instead of using a lot of TDAs.","PeriodicalId":256057,"journal":{"name":"Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference","volume":"228 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123036702","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}

Dynamic eccentricity produces low frequency air gap flux components, however they can be observed in stator current only under mixed eccentricity. Unlike MCSA (motor current signature analysis), described method allows to detect purely dynamic eccentricity or to detect dynamic eccentricity under mixed eccentricity with a minimal effect of static eccentricity. Although many papers have been focused on external magnetic field analysis, they have usually decribed other types of faults. In this paper the amplitudes of characteristic frequency components are predicted using FEM and some obtained results are verified by measurement. Both purely dynamic and mixed eccentricities are taken into account as well as saturation of magnetic circuit due to its significant influence on calculated spectrum.","PeriodicalId":256057,"journal":{"name":"Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131559148","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}
