This data is termed as a tradable asset for business. Most of the companies collect and store data of individuals to be used for direct activities such as providing better services to their customers, or to be released for non-direct activities such as analysis, doing research, marketing and public health. This collected data may include sensitive information like criminal records, financial records and medical records, which may result in privacy threats if compromised. A number of approaches are used to ensure Privacy-Preserving Data Publishing (PPDP). But most of the existing methods don't prevent all main privacy disclosure attacks or cause substantial loss of information. In order to prevent membership, identity and semantic similarity attacks while maintaining usefulness of data, a hybrid approach is proposed in this paper. This approach combines the bucketization method of anatomization approach and generalization as well as suppression methods of anonymization approach to achieve the two major privacy requirements: (l, e) diversity and k-anonymity. Our experiment shows that from the view of data privacy, the proposed technique increases the diversity degree of sensitive values by 29% and 37% on average over (l, e) diversity and klredInfo techniques respectively. On the other hand from the view of information loss, the proposed technique reduces the Discernibility Penalty (DP)D by 30% on average over (l, e) diversity technique and increases it by 28% on average over klredIinfo technique. In addition, the proposed technique increased the Normalized Certainty Penalty (NCP) by 12% on average over klredInf technique. Hence the proposed technique preserves data privacy more effectively as compared to klredInfo and (l, e) diversity techniques while maintaining the utility of data.","PeriodicalId":381362,"journal":{"name":"2018 International Conference on Computing, Mathematics and Engineering Technologies (iCoMET)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130319558","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}

China-Pakistan Economic Corridor (CPEC) is a burning topic of fundamental research in energy projects due to reliance on energy imports and of sustainable development. This paper presents progress on the CPEC energy policies and an overview of energy demands & supplies to CPEC energy projects. An outline of the past developments in the energy projects in the Pakistan has been explained. Finally, Long-range Energy Alternatives Planning System (LEAP) model has been used for CPEC energy projects. In this paper, modeling and analysis of existing energy power projects and CPEC energy projects are performed using LEAP model and the results are compared. We have presented three scenarios that are Reference Scenario (RE), Coal Scenario (COA) and Renewable Scenario (REN) to forecast CPEC energy projects in LEAP that was performed from 2013 to 2030. Results indicated that Coal scenario is better while considering environmental and economic effects. This research is beneficial to the forecasting of the role of CPEC energy projects in order to meet high electrical energy in future here in Pakistan. Expected barriers to the change in the energy mix are discussed and are presented from predictable sources of renewable energy sources.","PeriodicalId":381362,"journal":{"name":"2018 International Conference on Computing, Mathematics and Engineering Technologies (iCoMET)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122827630","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 basic purpose is to analyze the behavior of the properties that affect the breakdown voltage, to optimize the results according to the requirement and to enable the researcher to predict results before the experimental work. As we know, if the applied electric field is provided above a certain limit even for few nano-seconds it could lead to the breakdown of transformer oil. There are certain factors and dielectric properties that affect the breakdown strength of transformer oil and compromising the throughput of the electrical system. The optimization technique used for this purpose is Genetic Algorithm because of its good results, simplicity, and ease of use. It can deal with multiple variables at a time. The considered factors that affect the breakdown voltages are temperature, permittivity, tan δ, viscosity, velocity of the particles. The gap length is considered as 10mm and the factors are optimized around breakdown voltage of 50KV. Generally, oil having breakdown less than 50KV requires oil reconditioning. Considering these factors are leads to analyze many other factor affecting the breakdown voltage.","PeriodicalId":381362,"journal":{"name":"2018 International Conference on Computing, Mathematics and Engineering Technologies (iCoMET)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124034388","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}

For obtaining optimum results and maximum efficiency, designers need to choose magnetic components materials very carefully so that high frequency parasitics could be handled effectively without compromising the system efficiency. This paper presents a brief overview of magnetic materials suitability for high frequency (MHz) planar transformer applications. It also presents a comparison of losses and temperature rise of planar magnetic cores made up of different magnetic materials categorized as F, P, R and L. EE core shape is used for designed transformer. The main idea is to find out which material category provides significant benefits in terms of losses and temperature rise for high frequency (MHz) planar transformer's core manufacturing. All results are based on 2D Finite Element Analysis (FEA) for 10W power level at 1MHz operating frequency. Results obtained by analysis shows that L category material possesses minimum losses at operating frequency 1MHz for power level of 10W. Results also signifies that L material is the most thermally stable material for 1MHz operation as its temperature rise is minimum among other core materials.","PeriodicalId":381362,"journal":{"name":"2018 International Conference on Computing, Mathematics and Engineering Technologies (iCoMET)","volume":"46 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132640583","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}

A wireless sensor network is consisting of huge number of small, inexpensive and resource constrained devices called sensing nodes. These sensor nodes are densely deployed to measure a given physical phenomenon. Currently, there exist enormous applications of WSNs in various domains, such as health care (e.g. patient monitoring and assistance), environmental monitoring (e.g. weather forecast, forest fire detection), natural disasters (e.g. flood detection and monitoring, earth quick), military (e.g. military equipment monitoring/surveillance, battle field management), business (e.g. products monitoring and tracking) and smart homes (e.g. monitoring and controlling home appliances). Note that in all above mentioned applications of WSNs, the organizations / enterprises or even individuals take critical decisions on the basis of gathered data from WSNs. We advocate that if the gathered data is accurate and trustworthy, the decisions taken based on that data might be correct, otherwise it will guide the organizations/enterprises in erroneous direction. Since, in WSNs the sensor nodes are interconnected with each other through some wireless channel and use most of the time multi hop ad hoc topology, it makes them vulnerable to various security threats and one of the less addressed security threat of WSNs is the data provenance. It represents one of the key issues in examining the trustworthiness of sensor's data. Thus, the focus of this paper is to provide a detailed review of the state-of-the-art data provenance schemes for wireless sensor networks (WSNs). This paper could serve as a beginning guide for the researchers who just started to explore the domain of data provenance for WSNs.","PeriodicalId":381362,"journal":{"name":"2018 International Conference on Computing, Mathematics and Engineering Technologies (iCoMET)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131562335","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}

Minimizing the effect of multipath fading channels is crucial for any network performance. This paper investigates the influence of fading channels on the performance of ZigBee using IEEE 802.15.4 PHY layer with direct sequence spread spectrum (DSSS) technique and offset quadrature phase shift keying (OQPSK) modulation. Least mean square adaptive linear equalizer (LMS ALE) is combined to the system to minimize the channel effects. Performance and design analysis are presented in details. In addition, two design optimization procedures for the adaptive equalizer based on genetic algorithm (GA) and particle swarm optimization (PSO) are proposed. The multi-objective optimizations aim to choose the equalizer design parameters that achieve the optimum ZigBee transceiver steady-state and transient performance. For verification purposes, the proposed design is simulated and tested in MatLab environment at different network scenarios. The results certify the ability of the proposed technique to extract the original transmitted signal at the receiver with minmum bit error rate (BER) and maximum speed of adaptation.","PeriodicalId":381362,"journal":{"name":"2018 International Conference on Computing, Mathematics and Engineering Technologies (iCoMET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122005501","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}
