Efficiency of any route discovery process depends on the length of the discovered route and the total number of messages exchanged over that route. Specifically in Wireless Sensor Networks (WSN) these factors have direct impact on the energy of sensor nodes and thus on the overall network lifetime. This paper adopts the theory of Small World Phenomenon to discover the short and long range paths between any given source-destination pair. OPNET based simulations are carried to evaluate the performance parameters such as number of messages, and network level energy consumption. Simulation results show 8% reduction in energy consumption and 40% reduction in message exchanges throughout the network by using the proposed mechanism.","PeriodicalId":174378,"journal":{"name":"2015 IEEE 10th International Conference on Industrial and Information Systems (ICIIS)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132310256","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}

Direct and Indirect discretization of the s to z transform is the commonly used technique for the design of Fractional order differentiators and Integrators. In this paper, second and third order s to z transforms are reduced to first order one by using model order reduction techniques. These novel transforms are used for the discretization. The designed filter coefficients are tabulated. All simulations are carried out using MATLAB.","PeriodicalId":174378,"journal":{"name":"2015 IEEE 10th International Conference on Industrial and Information Systems (ICIIS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127526282","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}

To reduce this gap a study has been done to measure the properties of a commercially available natural ester based insulating liquid and compared its ageing performances with conventional mineral oil based insulation. Moreover, ageing behavior of cellulosic pressboard insulation in the natural ester is also compared to that of in mineral oil. This study simulate the FDS response of both mineral and natural ester filled transformer under different conditions including, oil replacement, drying out of solid insulation and replacement of aged mineral oil with new natural ester based insulating liquids.","PeriodicalId":174378,"journal":{"name":"2015 IEEE 10th International Conference on Industrial and Information Systems (ICIIS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133052666","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}

During transformer operation oil may expose to various stresses such as electrical, thermal, chemical etc. As a result electrical properties of the oil may be degraded and hence leads to transformer failures. This study aims at monitoring condition of field aged oil and establishing any correlation among electrical properties. Twenty four oil samples (750 ml each) were collected from field aged transformers. The samples covered a wide spectrum of field ageing from one year to 40 years. First, colour of the collected oil samples were observed and categorized according to standard colour code (ASTM-D1500). Then electrical properties were obtained by frequency domain spectroscopy (FDS) measurements and breakdown voltage tests. The FDS measurements give the frequency dependent complex capacitance (C' & C\") and loss tangent (tanδ). Measurements were further utilized to estimate conductivities of the oil samples. As one may expect longer service life (i.e. longer ageing time) leads to darkening of the oil and lower breakdown voltages. The loss tangent and colour code has a reasonable good negative correlation with the breakdown voltage. The loss tangent and permittivity has a good positive correlation. However colour code and breakdown voltage does not have a correlation with the permittivity.","PeriodicalId":174378,"journal":{"name":"2015 IEEE 10th International Conference on Industrial and Information Systems (ICIIS)","volume":"35 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133636653","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 accurate determination of limb lengths is crucial for not only constructing the limb motion trajectories which are used for evaluation process of human kinematics, but also individually recognising human beings. Yet, as the common practice, the limb lengths are measured manually which is inconvenient, time-consuming and requires professional knowledge. In this paper, the estimation process of limb lengths is automated with a novel algorithm calculating curvature using the measurements from inertial sensors. The proposed algorithm was validated with computer simulations and experiments conducted with four healthy subjects. The experiment results show the significantly low root mean squared error percentages such as upper arm - 5.16%, upper limbs - 5.09%, upper leg - 2.56% and lower extremities - 6.64% compared to measured lengths.","PeriodicalId":174378,"journal":{"name":"2015 IEEE 10th International Conference on Industrial and Information Systems (ICIIS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113992950","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}
