Izydorczyk","doi":"10.1109/MELCON.2010.5476034","DOIUrl":"https://doi.org/10.1109/MELCON.2010.5476034","url":null,"abstract":"In the present article a method of lossless nonuniform transmission line (NUTL) analysis is proposed. The method reduces analysis of the NUTL to the analysis of cascaded sections of linear varied transmission line (LNTL). Frequency response of each section is described by Bessel functions. Therefore direct implementation of the method in circuit simulator is usually impossible. LNTL input-output relations can be approximated by rational function in frequency domain. It is a form of Padé approximation. The model can be implemented in circuit simulator as an active circuit. Unfortunately circuit input reflection coefficient is distorted in unacceptable manner. Input reflection coefficient is equal for DC to one irrespectively of order of Padé approximation. Author proposed a method which deforms rational approximation residua slightly so frequency response of the model is disturbed minimally and passivity of the circuit is preserved. Synthesis of the passive modeling circuit was conducted for broad range of LNTL slope parameter. The circuit was a cascade connection of Darlington C-type sections. Parameters of the sections were approximated by polynomial regression functions. The specific insensitivity of cascaded circuits on parameter changes assures high accuracy of the model despite inevitable errors in process of parameter regression.","PeriodicalId":256057,"journal":{"name":"Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116413214","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}

Most of them focus in raising issues as routing algorithms, network lifetime, and more recently, Multiple Input Multiple Output wireless networks. In contrast with all those studies, we present a practical application of wireless networks: The sensing of the pH and temperature for a fish farm. The application requires two different kind of modules: the sensor itself and the wireless module. The sensor collect and transmit the information to a wireless module using a wired connection. Once the information reaches the wireless node, it is forwarded to the central unit through a wireless protocol. The central unit starts and manages the network, as well as stores all the received data. The sensor module includes an pH sensor based on a specially designed ISFET and a commercial temperature sensor. The wireless node collects the sensed data by means of an asynchronous wired serial polling communication. The use of this kind of protocol allows to connect a single master with multiple slaves. In our particular case, we have connected one master with four slaves using a transmission rate of 9600 b/s. The wireless transmission follows the standard IEEE 802.15.4, and implements the routing protocol based on the ZigBee standard. The number of nodes distributed in the fish farm has been limited to 30 while the maximum number of hops to 6. Moreover, between the MAC and the routing layer an energy management layer have been included. This layer reduces the power consumption of the wireless network using an RF activity duty cycle for the reception stage at the final end device of around 0.02%.","PeriodicalId":256057,"journal":{"name":"Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130625262","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}
