Some of the Distributed Generators (DGs), those are dispatchable and have high capacity, can individually participate in the power market but they may choose VPP if they hope to reach a higher benefit in the power market through VPP. Some of the others, those are very small or have stochastic nature, can not gain access to the power market without aggregation. Depend on the capacity and characteristics of distributed energy resources, their aims for joining to VPP and their dependency to VPP may be different. VPP may be their ownership, their operator or only an interface entity that can facilitate more economical opportunities for them in the power market. This paper characterizes a general framework for VPP which can be included the various DG technologies in both medium and low voltage distribution networks. Based on the degree of dependency to VPP, the VPP components are categorized into three classes, i.e. market component parts, contractual component parts and internal component parts, and also their trading relation with VPP are discussed.","PeriodicalId":163141,"journal":{"name":"2009 2nd International Conference on Adaptive Science & Technology (ICAST)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126954726","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}

That is, a system that learns to fly a helicopter the way a human pilot would. It draws on the benefits of using inverse simulation and genetic algorithms to model systems similar to human process. The goal is to define tasks for the helicopter and have the pilot find control settings that carry out those tasks. The inverse simulation technique generates the control inputs required for a desired set of motion outputs. Genetic algorithms (GA) generate feasible solutions to the inverse problem in which the helicopter's trajectory is defined as a set of way-points. The continuous controls encoding method was implemented in flying a longitudinal acceleration/deceleration maneuver. The helicopter pilot was formulated as a multi-optimization problem with four objectives imposed as penalties. The work proposed an optimization approach termed maxPenalty, which compared and returned the biggest of the four penalties. The GA attempts to maximize the fitness and while minimizing the pilot workload. The work shows some aspects of the GA-produced flight that are human-like, and the fact that humans do not move along precise trajectories.","PeriodicalId":163141,"journal":{"name":"2009 2nd International Conference on Adaptive Science & Technology (ICAST)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122161912","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 addition it shows that the call for a new paradigm incorporating existing economic activities within these communities is surfacing. The main research question discusses what policy framework enables beneficial use of ICTs on both a national and communal level. The paper does so by researching recent literature to combine the advantages of both the national and communal approach and by using Egypt as a case study to derive components of a framework and to construct a new framework policy to improve Egypt's governance approach to social project development. It is concluded that such a combination is possible. Furthermore, a new framework is presented that incorporates a governance approach to social project development and that supports the aim of ICT4D to economically advantage the people it was originally designed for.","PeriodicalId":163141,"journal":{"name":"2009 2nd International Conference on Adaptive Science & Technology (ICAST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125975716","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}

Considering the increasing utilization of VoIP (voice over IP), it is important to adequate the UMTS systems to this technology, in order to maximize the efficiency of transmission over the air interface. This paper considers a new contribution in this direction, based on the reduction of VoIP packet overhead, aiming to lower power consumption during a typical conversation. It is well known the advantages of HSPA systems for VoIP transmission, but at this moment there are only a few networks commercially available using this technology.","PeriodicalId":163141,"journal":{"name":"2009 2nd International Conference on Adaptive Science & Technology (ICAST)","volume":"300 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127614985","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 follows that public safety organizations in developing countries are faced with increasingly volatile environments—sometimes in absence of resources that they direly need. Among these resources are modern technological and tactical tools that help to provide timely response to crises situations, aid in conflict prevention and support day-to-day management functions. To this end, the design and implementation of an integrated homogenous Vehicular Information and Communications Technology (VICT) system, which must be robust, resilient and secure, can be significant force multiplier.","PeriodicalId":163141,"journal":{"name":"2009 2nd International Conference on Adaptive Science & Technology (ICAST)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115945715","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 paper presents two feedforward neural networks for conditioning the mV output of the type-B thermocouple: one, a two-layer network for structural identification and the second, a radial basis network for repeatability enhancement. The networks were trained in MATLAB. Results show that complete thermocouple data could be reproduced using the logistic network.

Good quality ECG are utilized by physicians for interpretation and identification of physiological and pathological phenomena. However, in real situations, ECG signals are corrupted by artifacts. So the noise removal is a classical problem in ECG records, that generally produces artifactual data when measuring the ECG parameters. The Block LMS (BLMS) algorithm, being the solution of the steepest descent strategy for minimizing the mean squared error in a complete signal occurrence, is shown to be steady-state unbiased and with a lower variance than the LMS algorithm. In this paper, we present a BLMS algorithm for removing artifacts preserving the low frequency components and tiny features of the ECG. Finally, we have applied this algorithm on ECG signals from the MIT-BIH data base and compared its performance with the conventional LMS algorithm. The results show that the performance of the BLMS algorithm is superior than the LMS algorithm.","PeriodicalId":163141,"journal":{"name":"2009 2nd International Conference on Adaptive Science & Technology (ICAST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129673115","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}
