Item An efficient electricity theft and fault detection scheme in distribution system(Science International, 2016) Muhammad Fahad Zia; Fahad AliCurrently the world is facing energy (electricity) crisis and it is becoming severe with the passage of time. Every country is striving to produce and save electricity. In developing countries, especially, a considerable amount of revenue is lost due to electricity pilferage and fault occurrence on the distribution system. Therefore, it is required to design a system that would be able to detect electricity theft as well as the faults on the distribution system. This paper presents an efficient and simple technique which operates efficaciously as an electricity theft detector and also serves the function of a protective relay. In this scheme, each customer is provided with smart meter and a main observer meter is connected to distribution transformer. Meters send the readings to the data acquisition center where the proposed algorithm is applied to detect theft or fault scenario. Electricity theft can be considerably reduced by using this proposed metering technique. This algorithm can also identify associated areas of electricity theft.Item Exact solutions of second order obstacle problems using reduction-to-first order method(Science International, 2016) Shaukat IqbalIn this article we used the Reduction-to-First –Order method to solve the systems of second order boundary value problems. Two examples are presented to get exact solution, which illustrate the effectiveness of the method.Item GUI based fuzzy logic control system(Science International., 2016) Muhammad Tahir MushtaqThe work presented in this paper addresses a generalized graphic user interface(GUI) based Fuzzy Logic Control System(FLCS) to design, edit and execute control system. The proposed system is a user friendly and easy to implement. It helps the user to create a fuzzy logic system in simple steps, inserting the names and membership functions details of all inputs and outputs defining the rule base for FLCS. Detailed structure of the system and design of modules, fuzzifier, inference engine, rule base and defuzzifier were discussed. The results of proposed model were compared with the results of MATLAB Simulink. This research work proposed to develop a novel control system to create and succeed FLCS in few steps efficiently.Item Position Control of Switched Reluctance Motor Using Super Twisting Algorithm(Mathematical problems in Engineering, Hindawi, 2015) Shaukat IqbalThe inherent problem of chattering in traditional sliding mode control is harmful for practical application of control system. This paper pays a considerable attention to a chattering-free control method, that is, higher-order sliding mode (super twisting algorithm). The design of a position controller for switched reluctance motor is presented and its stability is assured using Lyapunov stability theorem. In order to highlight the advantages of higher-order sliding mode controller (HOSMC), a classical first-order sliding mode controller (FOSMC) is also applied to the same system and compared. The simulation results reflect the effectiveness of the proposed technique.Item Unsteady Boundary-Layer Flow over Jerked Plate Moving in a Free Stream of Viscoelastic Fluid(The Scientific World Journal, 2014) Sufian Munawar; Ahmer Mehmood; Asif Ali; Najma SaleemThis study aims to investigate the unsteady boundary-layer flow of a viscoelastic non-Newtonian fluid over a flat surface.The plate is suddenly jerked to move with niform velocity in a uniform stream of on-Newtonian fluid. Purely analytic solution to governing nonlinear equation is obtained. The solution is highly accurate and valid for all values of the dimensionless time 0 ≤ 𝜏 < ∞. Flow properties of the viscoelastic fluid are discussed through graphs.Item Internet markets & e-advertising active models in Pakistan: Signifying e-advertising artifacts apposite for e-business startups(2012) Hammad Mushtaq; Imran Sadiq; Syed Nouman AliIn recent years internet market continues to maturely expand at even more pace than ever before. In Pakistan entrepreneurs and organizations are accepting web technologies to expand businesses utilizing the robust dynamics of Internet Marketing and e-Advertising. The e-Advertising artifacts offer wide range of benefits to business community such as interactive and personalized e-ads, social media and use of SEO to reach target customers precisely. This study is focused on attempt to mark the trend for adoption of such models in Pakistan e-Business startups and their effectiveness. There are variety of advertising models available in e-Advertising i.e. Search engine marketing, permission advertising, affiliate advertising etc each with its own unique features. The core benefits of e-advertisement are measured in terms of creating brand awareness, attracting customers and improving brand loyalty. The literature review establishes a sphere highlighting use of internet in businesses around the globe generally and Pakistan especially. Furthermore, a close study of Pakistani environment has been taken as a test case to understand and develop an e-Advertising model for e-Business startups. The e-Advertisement adoption model suggests artifacts that are most suitable for e-Business startups considering their specific needs. This model will be helpful for organizations in Pakistan who wish to utilize the exciting features of e-Advertisement artifacts such as feedback of e-Advertisement campaigns or just in time advertisements.Item Prospects of adopting on-line advertising: firms practicing e-businesses in Pakistan(COMSATS Institute of Information Technology, 2009) Hammad Mushtaq; Haroon RashidGrowing awareness in Business community of Pakistan for adopting technology to expand businesses in-land and overseas has made place for utilizing various e-advertisement models. Thus using technology advancement that produced wide range of advertisement models which offer benefits to business such as interactive and personalized e-ads and reaching target customers precisely in advertisement campaigns. There are variety of advertising models available i.e. search engine marketing, permission marketing, affiliate marketing etc each with its own unique features. This study is focused on marking the trend for the adoption of such models in Pakistan business industry and effectiveness of such models. It is apparent that specific economic, socio-technical & cultural factors has their impact on devising electronic advertisement practices of organizations in Pakistan. The core benefits of electronic advertisement are measured in terms of creating brand awareness, attracting customers and improving brand loyalty. The e-advertisement adoption framework will be helpful for organizations in Pakistan who wish to exploit the exciting features of e-advertisement such as feedback of e-advertisement campaigns or just in time advertisements.
