The main objective of this study was to use a watershed scale model SWAT (Soil & Water Assessment Tool) as a modeling tool for predicting the impact of the Land Use change on water quality of Rawal Lake. Specific objectives were to (a)develop pollution source inventory mapping(b) quantify the pollutant load (organic nitrogen and phosphorus) with respect to Land Use change that causes eutrophication and (c) model the alternative Best Management Practices (BMP’s) and evaluate their effectiveness. In the pre field phase the collection and preprocessing of data (DEM & Landsat images (30m resolution)) was done. Land Use (2001 & 2010) classification was done using Landsat imagery in ArcGIS. For the pollution source inventory, mapping the study area was surveyed. In the post field phase the model was calibrated (2002-2006) by using the observed and simulated surface runoff data and then validated (2007-2010) .The, model’s accuracy was further verified by using R2 and Nash Sutcliffe Efficiency (NSE). SWAT simulations resulted in 392.40 % and 391.72 % increase in the quantity of organic nitrogen and phosphorus with respect to Land Use change (2001 & 2010). By the application of BMP’s such as filter strips, the average reduction in the concentration of N could be 75.155% while that of P could be 96.93%, similarly by the application of terracing the average reduction in the concentration of N could be 52.73% while that of P could be 94.18% in the selected sub basins. By the application of contouring the average reduction of 35.64% for N and 92.09% for P could be achieved. This study would provide decision maker a source of information on most feasible and cost effective BMP’s.","PeriodicalId":19924,"journal":{"name":"Pakistan Journal of Scientific & Industrial Research Series A: Physical Sciences","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79059412","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}

Before and especially during Covid-19 pandemic pulse oximeter is most necessary in intensive care units (ICU) and in operation rooms but there is a general shortage of such equipment and the one that is available is very expensive. In this project we aim to create an affordable device that allows a person to measure their physiological parameters and provide breathing support so that it may be used in homes and in medical facilities. This device is controlled by programmable microcontroller with some peripherals and sensor. First, the device was built in breadboard afterward it was built on vero board. This device is based on the variation of photon. This device measures pulse rate, body temperature and oxygen level with oxygen saturation of hemoglobin in blood. This device allows a patient to monitor their health at home which is especially useful for Covid patients observing self-isolation and it can be easily set up in remote areas and can be operated on battery. It is an affordable method of allowing people to monitor their health and avoid frequent visits to hospitals and clinics. The device contains a bag valve mask (BVM) that is compressed using a motor to allow for breathing supports for patients in critical condition.\u0000'Drought,' 'After Drought,' and 'No Drought.' DenseNet, ResNet, InceptionV3, Xception, and VGG19 deep learning architectures were utilized for training the models. Accuracy, Precision, Recall, F1-Score, and ROC curves were used to evaluate all models. According to the experimental results, DenseNet and ResNet were the best-performing models with an accuracy of 70%, while VGG19 was the lowest-performing model with an accuracy of 60%.","PeriodicalId":19924,"journal":{"name":"Pakistan Journal of Scientific & Industrial Research Series A: Physical Sciences","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78065213","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 main essence of geographically distributed software development is to expand company working by follow-the-sun strategy, get skilled labors at cheaper rates from low economy regions of world and pool-up company resources to raise their utilization graph. The requirements elicitation process is considered as one of the most challenging tasks during software development process in traditional as well as geographically distributed software development projects due to its social and collaborative nature. This article presents a comprehensive insight about major challenges faced by requirements elicitation teams engaged in geographically distributed software development projects. The article also elaborates the possible strategies, which can be adopted to minimize the negative impact of geological distribution of software development activities. The presented study will help the requirements elicitation teams to better plane their requirements elicitation sessions for geological distributed software development projects by encountering the expected hurdles.","PeriodicalId":19924,"journal":{"name":"Pakistan Journal of Scientific & Industrial Research Series A: Physical Sciences","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80206116","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 interaction of electric vehicles to an intelligent grid by accomplishing a synergistic affiliation to disseminate power is vibrant for refining on its way. The aptitude of EVs fleets to turn as one unit for surplus energy storage allows for the mass integration of renewable sources into a conventional grid structure. In this study, a vehicle equipped with V2G functionality offers numerous features such as support for actual and reactive power, load leveling, filtration of current harmonics, etc. Nevertheless, the concept of V2G additionally arises noticeable issues, like depletion of batteries, communiqué bottleneck between grid and vehicle, a modification for the design of a distribution network.

The task may be about conveying some information to a person when the user meets him, sort things in his wardrobe, or locker, etc. A user can meet the person anywhere or anytime so he cannot set a reminder for a specific time. Such tasks can be accomplished if the user has a reminder system, which reminds him about the tasks at runtime. In this paper, we present a reminder system based on speech recognition & speaker identification; personal voice- controlled aid for the user to remind about the tasks when some specific keyword/phrase is spoken by the user or user reaches a specific location so that the user can accomplish the important time independent tasks without being time-bound. The specified keyword can be anything, person name, place name, and any phrase. The user can speak to the assistant to remind about some task without un- locking his mobile or opening the application for a specific keyword/phrase & location. When the specific keyword/phrase is spoken or user reaches the specific location the assistant also speaks and reminds the user about the task. Voice reminder assistant supports Text-Independent Speaker Identification unlike other voice assistants already available.","PeriodicalId":19924,"journal":{"name":"Pakistan Journal of Scientific & Industrial Research Series A: Physical Sciences","volume":"67 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83849707","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}
