Item Enhancement of wind power generation in Pakistan.(Science International., 2015-01) Ahmad Chaudhry, IjazThe widening gap between supply and demand of electricity is a global issue and it needs serious attention. For sustaining economic growth and development, many countries are facing the challenge of high energy demand. The conventional source of energy, fossil fuels, are depleting rapidly. The environmental impact of these fossil fuels are alarming, worsening air pollution. The cost of imported fossil fuels is also increasing. So, there is an urgent need to find energy sources that are reliable, environmental friendly and cost effective. Worldwide, people have shown great interest in developing renewable energy sources. Renewable energy resources are the best replacement of conventional energy resources, but renewable energy resources alone cannot provide for the energy demands of our country. In fact, we need a share of both of them to cope up with the energy requirements of our country. In this study, we will investigate present energy scenario of Pakistan, enhancement of wind power generation in Pakistan, energy policy of Pakistan and solutions for ending energy crisis in Pakistan. Pakistan has plenteous available renewable energy resources of which wind energy has many advantages. Wind energy has attracted many countries and is being used by them to generate electricity. Many countries of the world have adopted this technology as wind is extensively available, has no effect on environment and is low cost. It is a successful, developed, cutting-edge, excellent and leading technology that has a large possibility for the generation of electricity in Pakistan. Several wind projects in Pakistan have been initiated and they have shown very encouraging and assuring signs of future success.Item Compare Cost of Good Quality & Cost of Poor Quality And Have a Wise Decision: A study from Automobile Industry of Pakistan.(IOSR Journal of Business and Management., 2015-09) Ashraf, Syed RehanFor the rationalization of improved quality, quality needs to be provided in numeric / monetary values, for this purpose cost of quality is measured and analyzed to get optimum levels. In this connection it is required to compare cost of good quality against cost of poor quality, to have a wise judgment of better choice. Survey was conducted in target population that helped in identification of importance of investment on cost of good quality rather than bearing loss due to poor quality. Furthermore, several other correlations were also identified between cost of quality and overall product cost. Purpose & Scope: Objective of the study is to find a quantifiable relationship of cost of good quality and cost of poor quality, so the importance of quality could be explained effortlessly and effectively. Study is carried out within the automobile industry of Pakistan, mainly in the northern part of country. Design / methodology / approach: In order to measure COGQ & COPQ, a structured format was developed and used for data collection (actual & hypothetical) through emails and in person interviews from industry experts. Findings: Study showed that the cost of good quality is 22 ~ 50 times lower than cost of poor quality and this comparative ratio is derived and may be used as rule of thumb. Originality / Value: COGQ is often compromised and ignored, as its ability to safeguard COPQ is not known in numeric terms or monetary values, this study has provided an example to calculate and compare these two costs.Item Development, control and stuctural analysis of bionic elbow joint.(Science International (Lahore), 2016) Rasheed, Faiza; Osaid, Hafiz Muhammad; Tabassum, Salim Abid; Ahmad Chaudhry, IjazDuring the last decade or so, Pakistan is unlucky to face the increasing number of amputees owing to a series of earthquakes, road accidents and terrorism. But the paucity of progress and advancement in the field of prosthetics is failing the provision of artificial limbs for doomed amputees. This field demands extensive work, consideration and dedication for amelioration of damned Pakistani populace. This research aims to provide amputees the potential for their routine life errands; to ameliorate their pecuniary and personal autonomy through the establishment of bionic elbow joint. Presently, many developed countries are functioning well in the realm of prosthetics, and are offering mobile and user friendly feigned limbs to amputees but a catholic research work is obligatory in Pakistan to create cost-effective and handy artificial limbs. This delve rally round to study the subject of biomedical engineering and its relevant techniques in detail with the help of Matlab, DAQNavi, ANSYS. It explores mathematical techniques and artificial intelligence for the study of electromyographic signals; likewise Artificial Neural Networks (ANN), dynamic recurrent neural networks (DRNN), and fuzzy logic system.Item On the turning modeling and simulation: 2D and 3D FEM approaches(Mechanics & Industry, 2014) Muhammad Asad; T. Mabrouki; H. Ijaz; Aurangzeb Khan, Muhammad; W. SaleemFor qualitative prediction of chip morphology and quantitative prediction of burr size, 2D and 3D finite element (FE) based turning models have been developed in this paper. Coupled temperaturedisplacement machining simulations exploiting the capabilities of Abaqus r with a particular industrial turning insert and a newly proposed geometrical version of this insert have been performed. Limitations of 2D models in defining the chip morphologies and surface topologies have been discussed. The phenomenological findings on the Poisson burr (Side burr) formation using 3D cutting models have been highlighted. Bespoke geometry of the turning insert has been found helpful in reducing the Poisson burr formation, as it reduces the contact pressures at the edges of tool rake face-workpiece interface. Lower contact pressures serve to decrease the material flow towards workpiece edges (out of plane deformation). In contrast, higher contact pressures at tool rake face-workpiece interface lead to more material flow towards workpiece edges resulting in longer burr. Simulation results of chip morphologies and cutting forces for turning an aluminum alloy A2024-T351 have been compared with the experimental ones. Finally, it has been concluded that the newly proposed geometry of the insert not only decreases the burr but also helpful in lessening the magnitude of tool-workpiece initial impact.
