Abstract: Background: The indiscriminate disposal of waste polyethene/plastic in some developing countries has become a huge challenge to those environments. Polyethene is a non-bio-degradable materials and when disposed indiscriminately causes drainage blockage, accumulation of moisture on asphalt pavements which eventually result in early pavement failure. Polyethene is a carbon-hydrogen (C-H) compound and possesses water proofing quality hence, could be used to modify bitumen for asphalt concrete production. Material and Method: This study was conducted to investigate the moisture resistance properties of asphalt concrete made from Pyrolized polythene....

Abstract: Engineering based SME is rapidly growing to be a key contributor to the national economy in Bangladesh by simultaneously creating jobs for the up-and-coming skilled labour forces, strengthening foreign currency resersve by reducing dependence on imported products for local industries and exporting high quality products. But growth of this promising field is often hinderd by the lack of internal R&D initiatives by the stakeholders. As a result, competing against international conterparts have become a struggle. In this work, we investigate widely used competeing automotive parts to identify parameters that contribute to the quality variation between local and imported components. We compare between......

Abstract: As electric wheelchairs are on a raising trend, there is plenty of scope in achieving a strong, lightweight and cost-effective wheelchair. This project illustrates some elegant engineering innovations in the chassis, motor and powertrain system that can help us achieve the goal. Furthermore, the project describes how the wheelchair can be converted into a stretcher and be used for transportation of patients and goods in hospitals or industries. As we proceed, we will see the designs, calculations and analysis for all the mechanical components such as power transmission, chassis and stretcher mechanism.

Abstract: Background: The pile construction is a complicated process in comparison open foundation construction, insufficient or inaccurate data collection from a geotechnical investigation may lead to unforeseen delays and cost variations during the pile installation. The characteristics of a soil influences the depth of pile, size of the pile, grade of the concrete, quantity of reinforcement in addition to super structure load. While, casting the pile, preventive measure shall be planned, practiced from pile side wall collapse and also verticality of drilling pile bore must be maintained. The excavated soil should be disposed as per contract agreement. In this paper work, the relationship (i.e. a model) among various factors have been constructed to assess the quantity of steel and also a equation (i.e. a model) among the factors......

Abstract: The demands for precautionary principles are increasing so fast in the global construction industry for bringing sustainability in a shorter period. While businesses are looking for high profit margins in a sooner period, sustainability related issues are rising or can be said it is being ignored most of the time. Therefore, several challenges are occurring that have been focused in the research work. For resolving those challenges, how the precautionary principles are helping has been illustrated with a clear overview by selecting several effective journals. The contribution of this work has justified the significance and reliability throughout the analytical journey.

Abstract: The target of this research is to study the effect of adding a simple-girder supported transfer floor on the behavior of a residential building. Numerical analyses of a 3-D model were conducted and the results compared to Elawady 2012 models. The 3-D model analyses were conducted using ETABS program. The program can be used to model high rise structures and to conduct nonlinear analyses accurately. It can practically & efficiently analyze structures up to 40 floors in height. The loading conditions can include pre-determined load conditions and combinations of loads necessary for proficiently modeling shear walls, [M.H., N.V.R., 2018]. Seismic forces were inserted by implementing the linear.....

Abstract: Cutting hard and high strength material such as Hardox 400 using conventional machining is extremely uneconomical and time consuming. Non-conventional cutting is usually performed on such material. In this paper cutting using laser technique will be tested to find how far the surface quality is deviated. In carrying out this investigation 3 main factors, namely, cutting speed, gas pressure and standoff distanceare considered as the input parameters. Their effects on the response parameters represented by the Kerf width of the cut, surface roughness quality and the heat affected zone are investigated.
