Abstract– In today’s world, the road and surface failure of the flexible pavement has become the most important and attention diverting problem, which may be due to the low quality of materials used, less and inadequate experience of the technical staff, and errors that may occur during the designing of the pavement. The design of thickness of the flexible pavement has taken the backbone place in determining the overall performance and providing high level of serviceability of the pavement structure for the heavy traffic loads under the adverse climatic conditions, during the expected design period. The aim of this research is to develop software for the flexible pavement design based on the AASHTO, Group Index, and CBR. This software can be used to determine the thickness of each layer, design life evaluation, knowing the relative damage factor, finding the various design variables like calculating the structural number and equivalent single axle load etc and climatic effects. The results obtained from this software were analyzed and compared with the theoretical (manual) design and with the DARWin, a design software of AASHTO, and were found absolutely feasible and accurate. This flexible Pavement software can save the precious time and avoid the errors and difficulties occurring during the conventional methods of design.

Abstract– the rate of success in higher education is of utmost importance for both students and academic institutions. Indeed, it is a turning point in the students’ life and a prerequisite for entering the professional world and/or developing a career. Additionally, higher-education institutions are competing in keeping a high retention rate and adequate transcripts with high students’ performance. Admissions’ entrance exams, school grades and SATs are some of the screening procedures that institutions exercise in order to monitor students through different programs of studies. Nonetheless, students are not usually fully aware of their choice when they apply for a major in terms of the requirements it shall imply, namely regarding special skills, which reveal only at advanced stages of their studies. In many cases, students fall under probation, face suspension and eventually have to change their major. The objective of this paper is to draft a clear and accurate assessment procedure that shall anticipate the aforementioned predicaments. The procedure will be developed using Educational Data Mining techniques and Neural Networks with the perspective of endowing both students and advisors the capacity of an early-stage decision-making tool based on the performance during the first year of studies and using specific courses, “relieffed” as indicators. Simulation results show the effectiveness of the suggested approach in terms of predicting academic issues at very early stages and offering pertinent guidelines and solutions thus, sustaining a higher retention rate in the different programs and majors.

To Know the Short and Long Term Improvement Works Required for the Bannu D.I. Khan Road

Abstract– Bannu is one of the most important districts of Province Khyber Pakhtunkhwa on the basis of its geographical location and strategic values. It serves as a gateway to the neighboring country Afghanistan and hence to the Russian federation and other linked countries. With the passage of time it has shown substantial economic, social, and industrial growth. As it works as a trade centre between the established areas & federally administrated tribal areas of Pakistan, and Afghanistan so its roads gets very congested. The main D.I Khan Road which connects it to the important and main trade zones of the country was reconstructed in 2003, and now the fast economic development, increase in population, and change in land use patterns has made it heavily congested. The length of road under observation has been divided into residential, commercial, and industrial areas according to its surrounding. From 2003 to 2011, the number of vehicles has increased by 51%, so the level of service it provides in all the three zones lies in category “F” of the HCM. As Pakistan is a developing country and its authorities don’t have enough funds to provide congestion free “A” level services, so this research was conducted to know short term policies to cope the problem, and according to results the level of service can be improved somehow by removing the encroachment and on-street parking specially in the residential area. But on the basis of existing situation, and keeping in view the building up peace in Afghanistan and the rapidly developing infrastructure in the tribal areas, the road passing through commercial and industrial areas would require extra widening.

Reduction of Power Loss of Distribution System by Distribution Network Management

Abstract– Reducing the losses of power distribution systems (technical and non-technical losses) is an absolutely necessary objective in the sound management of any electrical utility. The transmission & distribution losses in Indian power system are high. Recent progress in optimization practices and computer technology has made it possible to perform accurate analysis of the distribution system and distribution losses. Most of the efforts of power planners concentrate on augmenting supply by building new power plants. But saving is possible by improving operating conditions for the distribution network. Due to inadequate planning and methods adopted for load shuffling, some networks are under loaded while others are overloaded. Thus there is some scope for improvement in operating strategies. Network reconfiguration in distribution system is realized by changing the status of the sectionalizing switches and is usually done for loss reduction and avoids overloading. In primary distribution system (11KV), the need for reconfiguration occurs in emergency condition following the fault to isolate faulted section and in normal condition to reduce system losses or to avoid overloading of network. The main objective of the paper is to outline a methodology for management of distribution system for loss reduction by network reconfiguration.

Department of Mechanical Engineering, Nnamdi Azikiwe University PMB 5025, Awka, Nigeria

Abstract– The delay differential equations describing the turning and milling processes are solved using MATLAB and results compared. The same set of parameter combinations are used for turning tool, one tooth, three tooth and six tooth milling tools in generating graphical trajectories of cutting process. This resulted in the comparison that gave rise to the conclusion that under full-immersion conditions milling stability characteristics get closer to that of turning as the number of teeth of milling tool increases.
