Impact of Foreign Aid in Education Sector of Pakistan
(Library Information Services, CUI Lahore, 2018) Muhammad Ahsan; SP14-BECO-003; Ms. Zainab Naveed
The role of foreign aid in education in Pakistan has shown mixed results. The present study intends to explore the relationship between foreign aid and education sector of Pakistan using time series date from the year 1975 – 2014. To estimate the model Autoregressive Distributive Lag Technique has been applied. Empirical results confirm the presence of inverse relation between foreign aid and education in long and short run in Pakistan.
Impact of Risk Management Practices on Project Success: A Comparative study of Conventional and BOT Projects in Pakistan
(Library Information Services, COMSATS University Islamabad, Lahore Campus, 2018) Muhammad Ahsan; FA15-RPM-005; Dr. Sajid Nazir; LHR TP 5210
With the growing demand of public infrastructure projects, it is necessary to clearly identify, evaluate and manage the risk associated with the project. The study of this thesis aims to identify and compare the best practices of risk management in build operate transfer projects and conventional projects. This approach also combines aspects of soft and hard skills. This methodological approach involves a literature review to underpin the conceptual framework and a survey to identify the best practices of risk management in build operate transfer projects and conventional projects in Pakistan by using structural survey form. It is a quantitative research. A self-administrated questionnaire comprising of two parts: closed ended questions were asked about gender, age, organization, service, employment type and project. Other variables taken and used within study are linked with 5 points likert scale so that the respondents could select them according to their experiences and attitude towards the variables. The data was analyzed based on sample survey forms collected from reputed companies of Pakistan such as NHA, FWO and NESPAK. The fieldwork involved interviews with project managers and the professionals working on build operate transfer and conventional projects. The total sample size comprises of 70 respondents and the sampling technique that is used is simple random sampling. Further-more data is analyzed by using independent sample t-test. The structural model presented herein provides a means for correlating the hard and soft sides of risk management understanding the best practices of risk management in build operate transfer and conventional projects in Pakistan. The results of the study reveal the best practices of risk management in conventional and BOT projects and its impact on the project success.

Study on the Heat and Mass Transport of Non- Newtonian Powell-Eyring Model Fluid Over Variable Thicker Sheet
(Library Information Services, COMSATS University Islamabad, Lahore Campus, 2021) Muhammad Ahsan; CIIT/SP20-RMT-031/LHR; Dr.Mohsan Hassan; LHR TP 7635
Non-Newtonian fluids are used in a wide range of industries, including the polymer sector, the food industry, and even everyday life. The viscosity behaviour of these fluids identifies their rheological behaviour. Many factors affected viscosity change, including temperature, shear rate, pressure, and so on. When heat and mass flows are explored simultaneously, these effects cannot be underestimated, particularly temperature. In this thesis the problem for Study the Heat and Mass flow of Non-Newtonian Powell-Eyring model fluid is explored across a variable thicker sheet. The fluid is considered to be incompressible, laminar, non-newtonian over variable thicker sheet. All the programming is done on MATHEMATICA. The mathematical model is based on partial differential equations (PDEs) that represent continuity, momentum, and energy. To determine the model's solution, it is first converted into an ordinary differential equation (ODEs), which is then solved using the RK-Method. The model's output is presented in the form of velocity and temperature profiles, as well as various parameters.
