The modeling of PARR-II was performed using Monte Carlo based open source simulation program called OpenMC. The core modeling was validated with reference values taken from final safety analysis report of Pakistan Research Reactor-II. The calculated value of excess reactivity is 4.14mk with an error of about 3.5% and beryllium shim worth is 19.95mk with an error of 6% and these values were found in good agreement to the reference values. For neutronic beam modeling of beam tube using different materials were done and validated by comparing with beam parametric values found in literature. The selection of reflector, moderator and filters of definite thicknesses for beam tube is based on the required energy and magnitude of the neutron flux required at the exit of tube. The variation of the total and epithermal flux was studied and found that both fluxes decrease with the increase in thickness of both reflector and moderator. In this way an optimum value of moderator thickness 11cm selected according to values of flux (108 neutrons/cm2.s) and energy of neutrons required for therapy as provided by international atomic energy commission (IAEA).","PeriodicalId":285090,"journal":{"name":"2016 International Conference on Emerging Technologies (ICET)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124549309","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}

These photo-neutrons contaminate the therapeutic beam and are of concern to the personnel working around the treatment room. Consequently, study of neutron albedo is very helpful for radiation protection purposes. In this work, the integral neutron albedo is determined as a function of thickness of target materials using parallel beam of thermal neutrons for a number of materials important in radiation protection and medical purposes, including water, aluminum, lead, iron, beryllium, graphite, skin-ICRP, soft tissue-ICRP, muscle skeletal-ICRP using Geant4 Monte Carlo simulation code. These simulations clearly show that neutron albedo rises quickly with target thickness and reaches saturation after about 15 cm. The value of neutron albedo depends upon scattering material thickness and geometry of reflector and its physical properties. The results of this work have also been compared with those obtained with other experimental results and theoretical calculated values, and found a good agreement with simulated value. These calculations will be helpful for evaluating the outcome of future clinical treatment planning in LINACS, radiation protection and radiation safety. The study of these materials demonstrates that a large proportion of neutrons are reflected at the edge of reflector from 1 to 10 cm, further increasing thickness have relatively small effect on neutron-albedo.","PeriodicalId":285090,"journal":{"name":"2016 International Conference on Emerging Technologies (ICET)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114081220","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 mobile users moving in vehicles on the high ways, in streets and canyons are more critical to model their surrounding environments. In order to model such scattering environment, we extend the earlier proposed two-dimensional (2D) elliptical geometric channel model for macrocellular communication systems by introducing elevation of the base station (BS). We consider that MS is placed at the middle of the ellipse and surrounded by uniformly distributed scatterers on the boundary region of the ellipse. Furthermore, we also consider elevation of the BS that is installed in scattering-free region. Taking these assumptions into account, we derive a simple mathematical expression for the probability distribution functions (PDFs) of angle-of-arrival. The elliptical geometry is such that it has adjustable dimensions and can model the streets and highways in a better way according to their widths.","PeriodicalId":285090,"journal":{"name":"2016 International Conference on Emerging Technologies (ICET)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125593105","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}

Considering PHEV to stay for several hours in the parking lot may offer a unique opportunity to charge PHEV from photovoltaic power in those hours. The proposed charging facility is working under smart charging scheduling paradigm, which is independent from forecasting models of PHEVs charging. The proposed paradigm schedules of PHEV is in an optimal way based on two parameters i.e., priority levels of PHEVs charging, and variations in DC link voltage level. Furthermore, the priorities of PHEV charging are based on their power demand, maximum rating of distribution transformer and stay duration of PHEVs in the parking lot during high irradiation of solar effect. The sensing of proposed paradigm is based on change in DC link voltage. The DC link voltage changes due to variance in solar irradiance, temperature and real-time residential load. Such priorities are updated whenever smart charging scheduling paradigm detects changes in voltage and initiate/terminate PHEVs charging. Simulation results express the effectiveness of proposed charging station effectively.","PeriodicalId":285090,"journal":{"name":"2016 International Conference on Emerging Technologies (ICET)","volume":"37 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":"117263062","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}
