An attempt has been made to develop the Graphical user Interface (GUI) system for function approximation. This GUI system can handle the function approximation of any nonlinear/linear function which can have any number of input variable and 6 output variables. Parameters of neural network can be set from a single panel. This GUI system provides approximation for various functions which made this GUI universal for the wide range of the users without theoretical knowledge about the function approximation. A Neural network with a single hidden layer has been used to approximate the functions. To train the neural network various type of learning algorithms has been accumulated in GUI system. Two 2-D benchmark problem has been tested. Finally comparison has been made which shows that Levenberg-Marquardt (LM) back propagation with single hidden layer FFNN converges faster than other training algorithms.","PeriodicalId":439893,"journal":{"name":"2010 International Conference on Power, Control and Embedded Systems","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123666175","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}

Excitation of individual array elements is computed using the algorithms. Dynamic Range Ratio (DRR) of current amplitude distribution does not exceed a prefixed threshold value. Phase of the individual excitation is fixed at zero degree. Simulation results show considerable enhancements in array performances using the global optimizers. The paper finally illustrates a comparative evaluation of the three proposed algorithms regarding their applicability as numerical optimization techniques.","PeriodicalId":439893,"journal":{"name":"2010 International Conference on Power, Control and Embedded Systems","volume":"16 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120861768","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 slip control scheme has been used for the induction motor. The evaluation of the controller's behavior is made through computer simulation with MATLAB coding. The starting transients of the motor are investigated for different operating speeds. It has been shown that for fuzzy controller, once the parameters are selected for a specified load and speed, it works for all other speed whereas for conventional PI controller, the parameters have to change for each load and speed setting. The fuzzy controller reduces the over shoot value of speed approximately 2 to 5 % for the selected load. The peak value of input DC link current of the CSI is also less in fuzzy PI controller as compared to conventional PI controller. This reduces the rating of the semiconductor switches used in inverter and thus overall cost of the system.","PeriodicalId":439893,"journal":{"name":"2010 International Conference on Power, Control and Embedded Systems","volume":"15 17","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120966150","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}

All nodes have routing capability and forward data packets for other nodes in multi-hop fashion. Since many applications have QoS (quality of service) requirements such as delay and throughput, it is imperative that the wireless part of the communication should be able to support QoS similar to wired network. Numerous solutions to the QoS problems have been proposed in this context. However, these protocols did not consider a major aspect of wireless environments, i.e., mutual interference. Interference between nodes within the proximity of each other cause route coupling. This can be avoided by using zone-disjoint routes. In this paper we have evaluated the performance of priority based routing scheme, which will protect the high-priority flows from the contention caused by the low-priority flows. This priority based routing protocol avoids the coupling between routes used by high-priority and low priority traffic by reserving a high-priority zone of communication. We have use the low-priority call blocking to improve the throughput of high priority flows in a network.","PeriodicalId":439893,"journal":{"name":"2010 International Conference on Power, Control and Embedded Systems","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114130815","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}

Clusters create hierarchical WSNs which facilitate efficient utilization of limited resources of sensor nodes and thus extends network lifetime. ZigBee, a communication standard for LR-WPAN (Low Rate Personal Area Networks), has low power consumption, complexity and cost. ZigBee uses the IEEE 802.15.4 standard as its communication protocol for Medium Access Control (MAC) layer and physical (PHY) layer. The IEEE 802.15.4 MAC standard achieves duty cycle Operation by setting two system parameters, macBeaconOrder (BO) and macSuperframeOrder (SO), to achieve low power consumption for different value of duty cycle. In this Paper we have analyzed cross layer (MAC/PHY) approach for wireless sensor network scenario with clustering in which we consider LEACH(Low energy adaptive clustering hierarchy protocol) algorithms as clustering protocol and DYMO (Dynamic MANET on-demand) as a routing protocol and analyze improvement of clustered over not clustered WSNs. We have calculated the attributes like average jitter, end to end delay, throughput and total charge consumption for different % of duty cycle and have found improvement in network latency and average jitter.","PeriodicalId":439893,"journal":{"name":"2010 International Conference on Power, Control and Embedded Systems","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114153587","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 four controller design methods are Pole Placement method, Linear Quadratic Regulator (LQR), an Eigenvalue Assignment method for shaping the output response and a method based on Moore's Eigenstructure Assignment for controlling the linearized model of MIMO systems. In the Pole Placement method, some components overshoot, the convergence is slow and does not provide robust solution. LQR assures stability robustness with full state feedback but does not provide the flexibility of assigning eigenvalues and eigenvectors in placing closed loop structure.

Many papers have been published in this area. This paper is an effort to briefly review the categorization of various modes of noise generated by SMPS with fly-back converter topology. The effect of Mixed Mode noise is similar to Differential Mode noise but its sources are same as Common Mode noise. Therefore, Y-capacitors can be used to mitigate them. Frequency ranges of different modes are analyzed to show that DM noise is dominant in lower frequency ranges, CM noise is dominant in mid ranges and MM noise in higher ranges. A case study is then presented to investigate the effective use of Y-capacitor for the mitigation of Mixed Mode noise.
