The Kuan filter relies on the effective number of looks as a main parameter which is usually adjusted for each image, after several filter runs, in order to tune the filter for best performance. The proposed solution automatically estimates the optimal filter parameter value based on edge pixels statistics, which results in near-optimal performance where the PSNR loss, compared to the best possible filter output, does not exceed 0.1 dB most of the time.","PeriodicalId":149484,"journal":{"name":"2012 International Conference on Engineering and Technology (ICET)","volume":"BME-30 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114122158","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}

However, the limited energy source is the dominant factor where energy starvation occurs due to the large number of messages that need to be transferred through the network. In this paper, we propose new protocols to save the nodes energy as well as prolonging the overall network lifetime. Not like other protocols proposed in the literature, our protocols consider the accuracy/ reliability of the reported data to the sink node. Our first approach considers different types of wireless sensor networks including single and multimodal wireless sensor networks. Our second protocol utilizes the concept of distributed fuzzy logic agents for energy saving in wireless sensor network. Our approaches are extensively tested using simulation as well as real data captured from MIT WSN laboratory. In addition, the paper introduces a WSN prototype based on our data saving approaches. Our conclusion reveals promising results.","PeriodicalId":149484,"journal":{"name":"2012 International Conference on Engineering and Technology (ICET)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115392783","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 this quest, wireless communication technologies provide a brilliant option to reduce the connection effort. The vision is eventually to obtain equipment that may be described as “plug and play”. Nevertheless, the Substation environment is best describes as an electromagnetically harsh environment. To that end, the Zigbee technology is considered as an option. The advantage that Zigbee provides is the availability of multitude of parallel paths. Consequently, if one path is unavailable or “un-fit” to relay the message, another will do. The scope of this paper is to introduce a model of power system automation based on IEC 61850 and Zigbee wireless sensor networks (WSN) technology. The model considered is that of a D1 substation (Distribution substation with less than 5 controlled elements). The model is used to calculate time delays for Zigbee wireless network. Monte Carlo simulation is used to provide statistics to compare message delays in Zigbee to the IEC 61850 requirements. Results show that using multiple channels will improve performance to the fulfillment of IEC 61850 requirements.","PeriodicalId":149484,"journal":{"name":"2012 International Conference on Engineering and Technology (ICET)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116271256","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 changes in the yield stress and appearance of prolonged lüder's strain in the stress strain curves of static strain aged dual phase steel motivate studying the parameters affecting the formation and width of the lüder's strain as function of aging conditions. Static strain aging of fine grained (5 μm) CMn-CrNb dual-phase (DP700) ferrite-martensite steel was investigated. A 3.2 mm sheet thickness of dual phase steel of martensite volume fraction of 0.306 was used to examine the aging behavior at the temperature range of 100 to 500°C for aging times 5 to 180 minutes. Quasi-static tensile tests and optical microstructure investigation were performed on the aged and the as-deformed dual phase steel. The stress strain curves were determined and analyzed to detect the condition of onset of the lüder's strain. A constant aging time of 30 minutes at different temperatures has showed the onset Lüder's strain to be at 190°C while, a 60 minutes aging at 170°C was needed for the onset of the Lüder's strain. The extent of Lüder's strain was observed to be time dependant for the various applied aging temperatures. Lüder's plateau was characterized by a serrated flow within the Lüder's strain and has been correlated to dynamic micro-mechanisms of hardening and softening.","PeriodicalId":149484,"journal":{"name":"2012 International Conference on Engineering and Technology (ICET)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130431334","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}

Many models have been proposed for the HP-memristor based on the window functions. In this paper, we introduce a complete mathematical analysis of the controlled reactance-less oscillator for two different window functions of Joglekar's model (linear and nonlinear dopant drift) to discuss the effect of changing the window function on the oscillator's behavior. The generalized necessary and sufficient conditions based on the circuit elements and control voltages for both the linear and nonlinear models are introduced. Moreover, closed form expressions for the oscillation frequency and duty cycle are derived for these models and verified using PSPICE simulations showing an excellent matching. Finally a comparison between the linear and nonlinear models which shows their effect on the oscillation frequency and conditions of oscillation is introduced.","PeriodicalId":149484,"journal":{"name":"2012 International Conference on Engineering and Technology (ICET)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114501435","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}

Consequently, their recognition problems have challenged due to largely varying appearances and highly complex pattern distributions. However, the complementary properties of these two biometrics suggest fusion of them. Face recognition is more reliable when the person is close to the camera. On the other hand, gait is a suitable biometric trait for human recognition at a distance. Information from these two biometric sources, frontal of face and side of gait, are utilized and integrated at feature level. Face image is represented by the Active Lines among Face Landmark Points (ALFLP) feature vector. Gait image is represented by the Active Horizontal Levels (AHL) feature vector. Face and gait feature vectors are fused using a proposed effective fusion method. The proposed system was tested on CASIA database and the achieved results showed that the integrated face and gait features carry the most discriminating power compared to any individual biometric.","PeriodicalId":149484,"journal":{"name":"2012 International Conference on Engineering and Technology (ICET)","volume":"219 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122848084","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}

Morphological analysis is developed to investigate the best alternative solution for each design parameter. The evaluation criterion is the maximum power transfer from input vibration energy to the electrical output waveform. The standards for PEH are also presented to enhance the system performance.
