In order to give the force effect on the windings, clamps and pressboards, a mass-spring vibrating system is used as a model for study.

{"title":"Cluster Algorithm for Electing Cluster Heads Based on Threshold Energy","authors":"Ying Huang, Cong Huang","doi":"10.1109/ICECE.2010.657","DOIUrl":"https://doi.org/10.1109/ICECE.2010.657","url":null,"abstract":"One of important requirements for many Wireless sensor network applications is to prolong network lifetime. The cluster head consumes more energy than other member nodes, because it gathers data from its member nodes, processes it (e.g. data fusion), and transfers data to the sink node or to the base station that maybe located remotely. Therefore, the cluster head should be elected periodically within the cluster to avoid the quick death of the head node and make all node loads distribute evenly. Based on the extensive analyzing of those algorithms such as LEACH, a cluster algorithm for electing cluster heads based on threshold energy is presented. The lifetime is suggested to be expressed as to both the maximum last node dying time and the minimum time difference between the last node dying and the first node dying. In order to obtain the effect, threshold energy was obtained and evaluated. The threshold energy is related to the initial energy of each node (Eo), number of nodes(n), energy consumption of cluster head (ECch), and energy consumption of cluster members (ECcm). The main purpose is to obtain the maximum network lifetime. What we now have done just to analyse the static threshold energy. When the optimal Dynamic threshold energy is adapted in the algorithm, the lifetime can be prolonged while the performance of network can maintain unabated. Results demonstrate that this algorithm which is more effective routing protocol prolongs the network lifetime when cluster heads are elected with the optimal threshold energy.","PeriodicalId":6419,"journal":{"name":"2010 International Conference on Electrical and Control Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79246292","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 chaotic signals are non-stationary signals, and contain some of the peaks and mutations. The denoising method using the traditional Fourier transform analysis is powerless. The wavelet analysis can simultaneously carry on the analysis in the time frequency range to the signals, so that it can more effectively distinguish the mutant part of the signals and noise to achieve signals denoising. This article used threshold denoising principle based on wavelet transform. Denoising signals are reconstructed in order to achieve the denoising purpose. The denoising system applied the db9 wavelet of Matlab7.0 Toolbox and soft denoising method for collection of the primary waveform to wavelet analysis. Results illustrate that this method can extract characteristics of signals effectively and have good value in practice.","PeriodicalId":6419,"journal":{"name":"2010 International Conference on Electrical and Control Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84454027","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}
