Measurement of Urine Flow Rate is one of the important parts of Urodynamics. Uroflowmetry, part of Urodynamics, is a non-invasive test easy to implement. It involves measurement of urine flow rate and other associated parameters. This paper presents Urine Flow Rate measurement based on pressure measurement technique to examine the functioning and dysfunctioning of Lower Urinary Tract. For implementation of this technique special purpose probe is designed. Pressure sensor used is from MPX series. The output of the sensor is connected to Analog to Digital Converter and Microcontroller after signal conditioning and amplification. The main principle of measurement technique uses the air pressure in a closed tube above a column of water (urine). As flow rate changes, the level in container changes accordingly and the air pressure in the closed tube above the column will change proportionally. By measuring the air pressure and associated time the flow rate is calculated. Once flow rate is calculated the other parameters as decided by the International Continence Society like maximum flow rate, average flow rate, voided volume and total time for voiding, time for maximum flow rate are calculated and displayed on PC. The graphs of Volume (milliliters) versus time (second) and Flow rate (milliliters/second) versus time are plotted. These graphs have typical nature in normal functioning of lower urinary tract if, this nature gets changed then there might be some problem associated with this tract or patient may need further investigations. By observing this nature of graph Doctor used to do the diagnosis.","PeriodicalId":171993,"journal":{"name":"2012 IEEE 7th International Conference on Industrial and Information Systems (ICIIS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122817879","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}

Once the optimal condition is achieved the correlated interference signal components are cancelled out and the desired signal can be extracted as the Wiener filter error signal. In practice, for most applications, the signals in concern tend to be non-stationary in nature with fluctuating bandwidths. Thus, training the Wiener filter under such conditions is essential for proper interference cancellation. In our work it was noticed that the use of a narrowband training signal, which is unable to span the channel transfer function, results in incomplete tuning of the adaptive filter. This results in erroneous interference cancellation for bandwidth varying environments. On the other hand, it will be shown in this paper that through proper selection of a training signal that can span the entirety of the channel transfer function, the channel can be modeled properly through the Wiener filter leading to significant performance enhancement. This work also presents an analysis on the impact of different types of training sequences on the performance of interference cancellation systems. This will enable proper selection of training sequences for interference cancellation problems based on application requirements.","PeriodicalId":171993,"journal":{"name":"2012 IEEE 7th International Conference on Industrial and Information Systems (ICIIS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126771443","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 a number of GIS installations, the main design considerations involved in gas insulated equipment are at cone insulator, gas and metal interface. Hence there is a need for control of electric stress in order to reduce internal discharges, surface discharges to the enclosure surface. In conventional approach, in order to reduce such distortion of electric field, many techniques applied like, control of the spacer shape, additional shielding of electrodes for relaxation of electric field around spacer and low permittivity material of spacer, etc., from this point of view the new techniques of Functionally Gradient Material (FGM) spacer has been proposed in this paper. The applicability of FGM spacer for gas insulated power apparatus has been verified. In the FGM spacer, a spatial distribution of permittivity for the control of the electric field distribution in and around the spacer is used. The electric field calculations for several types of FGM spacers have been carried out using Finite Element Method (FEM). The electric field distribution along the radial distance of the spacer insulator has been obtained for various FGM materials and results are compared.","PeriodicalId":171993,"journal":{"name":"2012 IEEE 7th International Conference on Industrial and Information Systems (ICIIS)","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114840764","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 robots are initially arbitrarily placed on a 2D plane. The definition of the circle formed by these robots is governed by two strict rules (a) all robots should be positioned on the circle circumference (b) all robots should be uniformly placed on circle circumference. The software framework proposed in this paper utilizes two fundamental design patterns the decorator and the observer. Each robot is assigned a unique identity, which is used for conflict resolution in various situations. The model treats the environment as a first class entity providing partial support to the robots for circle formation. All robots are situated in this environment and when a robot is first introduced its position is known in terms of its x and y coordinates. The approach suggested in this paper is a leader-follower approach wherein the environment that determines the leader and then the leader determines the positions on the circle circumference for the follower robots, such that, the total distance travelled by each follower is minimum and therefore the distance travelled by all the robots to form a circle is minimized.","PeriodicalId":171993,"journal":{"name":"2012 IEEE 7th International Conference on Industrial and Information Systems (ICIIS)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123501641","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}
