These networks are very important in providing the Internet access to fixed and mobile terminal equipment. The main problem in WMNs (regarding to mesh routers and mesh clients) is a routing protocol, especially because it has to enable the access to network for both mesh and conventional clients. Access to Internet for wireless mesh networks is done via special mesh routers, the gateways. Several gateways may exist in a network. The main role of a routing protocol is to find way to establish connection between an end user and one of the gateways, as fast as possible, considering links status. This path should be optimized from the traffic distribution and path distance point. This paper presents one type of packet routing in wireless mesh networks based on Hopfield neural network. Artificial intelligence is used for path optimization. Distribution of local routing information and routing table updates is realized by mobile agents. In this way, network should have a simple way of routing information delivery and thus for effective user traffic support.","PeriodicalId":227890,"journal":{"name":"10th Symposium on Neural Network Applications in Electrical Engineering","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116417638","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 system consists of EMG amplifiers, force transducers, A/D converter, portable computer and software running in the LabView environment that allows real-time and detailed offline processing of EMG signals in time and frequency domains. We demonstrate the features of the system by using the example of analyzing the strategy to generate 80% percent of the maximum force for prolonged period of time. Force sensor was used to detect muscle fatigue (fall of the force bellow the selected threshold), and EMG recordings were used for the analysis which of the quantitative measures of EMG is correlated with this. We tested the following four methods of EMG measures: 1) median frequency, 2) short-time mean frequency, 3) mean frequency of scalogram and 4) fractal dimension. We show that the system is capable of providing reproducible results and could be used for diagnostics and basic research in motor control. The analysis shows that the median frequency used often is not the best predictor of fatigues, and the measure needs to be selected based on the relative activity of the muscle compared to its maximal activity.","PeriodicalId":227890,"journal":{"name":"10th Symposium on Neural Network Applications in Electrical Engineering","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128643368","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}

We suggest that the segmentation of time-frequency representation image of one-dimensional phonocardiogram signals (PCGs) could be effective for observing possible abnormal heart events. The fact that frequency bands of cardiac events overlap and that different heart dysfunctions can occur simultaneously make image event segmentation a difficult task. Ambient noise and artifact burden make the segmentation problem even more difficult. A method of “splitting and merging” algorithm involving region-growing based on seeds is presented. We demonstrate that this method contributes to design of patterns required for cardiac event recognition and identification on several examples presented here.","PeriodicalId":227890,"journal":{"name":"10th Symposium on Neural Network Applications in Electrical Engineering","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116123141","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 detailed derivation for all types of analogues of 037 is given and shown that they represent a special case of cyclic numbers whose digits and multipliers are equidistant. The derived generic formula for analogues of 037 is correlated with cyclotomic and generalized Golden Mean polynomials, by which is shown their relation with discrete self-similarity, why author named them the Self-similar Numbers.

The results are presented for an example being envisioned for rehabilitation: playing the Wii bowling with the specially constructed pantograph. The pantograph transforms the pointing-like movement into the appropriate motion of the WiiMote (hand held controller for Wii game); thereby, the user is playing Wii bowling with greatly simplified movement of the hand (range and speed) compared with normal play. The data analysis reduced the information to two key parameters for distinction of success vs. no-success: 1) maximal acceleration of WiiMote and 2) the acceleration of the WiiMote at the ball release time.
