Research and development professionals are seizing the opportunity to design and integrate more functions and services for smart home monitoring and control systems utilizing such microcontrollers. This paper presents a wireless irrigation system for a smart home garden that can be integrated with existing smart home control systems. The system consists of slave nodes and a master station each of which is equipped with a wireless microcontroller. Each slave node is equipped with a temperature sensor, a soil-moister sensor, a water valve, a microcontroller and a zigbee transceiver. The slave microcontroller reads and frames the surrounding temperature of the garden's grass and trees along with soil moisture. Then, the frame is forwarded to the master station via a zigbee ad-hoc network. The master station has an embedded fuzzy logic irrigation algorithm to water the grass and trees based on a set of rules. A home web-server is interfaced with the master station for remote access monitoring and operation. The proposed system can be operated as a stand-alone unit or can be integrated with existing home automation systems.","PeriodicalId":395644,"journal":{"name":"2015 International Conference on Communications, Signal Processing, and their Applications (ICCSPA'15)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127784630","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 likelihood ratio test (LRT) is considered as the optimal fusion rule when applied at the fusion center. However, applying the LRT at the fusion center requires both the channel state information (CSI) and the local sensors performance indices. Acquiring these information is considered as an overhead in a energy and bandwidth constrained systems such as WSNs. To avoid these drawbacks, we propose a modification to the traditional three-layer system model of WSN where the LRT is applied as a local decision method at the sensors level and an equal gain combiner (EGC) is used as a fusion rule at the fusion center. Applying the LRT at the sensor level does not require the CSI or the local sensors performance indices. It only requires the signal-to-noise ratio (SNR). Simulation results show that the performance of the proposed model outperforms the traditional model that applies either the maximal radio combiner (MRC) or Chair-Varshney fusion rules. In addition, it provides comparable performance to the traditional model that applies the LRT at the fusion center.","PeriodicalId":395644,"journal":{"name":"2015 International Conference on Communications, Signal Processing, and their Applications (ICCSPA'15)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114369688","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}

Ultrasound B-imaging is one of mostly used displaying method in radiology. Our developed method and program use of the principle of B-imaging and displaying in grayscale according to pulse-echo approach principle. The program is focused on measurement echogenic area inside defined ROI. So, we measure level of echogenicity for examined tissue. It is based on binary thresholding due to grayscale displaying. We observe how echogenic area is changed according to threshold. Results were verified by an experienced sonographer and also by independent observers. We also observed average correlation between different ultrasound machines (r > 0.82) and between observers (r > 0.85, inter-kappa > 0.83, intra-kappa > 0.9). Up to now we tested the program for substantia nigra echogenicity to Parkinson's Disease diagnosis, raphe nucleus echogenicity and currently we examine atherosclerotic plaques in B-images with high correlation between 2 independent observers (r > 0.75) in a pilot study. Due to reached results of verification we proved the developed algorithm should be universally used in many diagnostics in which is B-MODE used, not only in neurology.","PeriodicalId":395644,"journal":{"name":"2015 International Conference on Communications, Signal Processing, and their Applications (ICCSPA'15)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127280578","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}

Modern digital control systems require fast on line and sometimes time varying solution schemes for differential equations. This paper presents new nonlinear adaptive numeric solutions for ordinary differential equations (ODE) with initial conditions. The main feature is to implement nonlinear polynomial expansions in a neural network-like adaptive framework. The transfer functions of the employed neural network follow a power series. The proposed technique does not use sigmoid or tanch non-linear transfer functions commonly adopted in conventional neural networks at the output. Instead, linear transfer functions are employed which leads to explicit power series formulae for the ODE solution. This allows extrapolation and interpolation which increase the dynamic numeric range for the solutions. The improved and accurate solutions for the proposed power series neural network (PSNN) are illustrated through simulated examples. It is shown that the performance of the proposed PSNN ODE solution outperforms existing conventional methods.","PeriodicalId":395644,"journal":{"name":"2015 International Conference on Communications, Signal Processing, and their Applications (ICCSPA'15)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130042987","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}
