Abstract: Steel casting is a specialized form of casting involving various types of steel. Steel castings are used when cast irons cannot deliver enough strength or shock resistance.Examples of items that are steel castings include: hydroelectricturbine wheels, forging presses, gears, railroad truck frames, valve bodies, pump casings, miningmachinery, marineequipment, turbochargerturbines and engine cylinder blocks.Steel castings are categorized into two general groups: carbon steels and alloy steels.Steel is more difficult to cast than iron. It has a higher melting point and greater shrinkage rate............

Abstract: A water network of 24 pipes depending on mainly gravity and covers an area of 3.78 square kilometers was taken an as a case study to test and compare the analysis. The governing equation of this network are internal flow in pipe equations, which consist of the continuity equation, the modified Bernoulli's equation, and the head loss due to the length of the pipe. The three equations are nonlinear algebraic equations because of the square power of the discharge in the head loss equations, which need to be solved numerically. Hard Darcy method and Newton Raphson method are used to solve the system of nonlinear equations, and to compare the solution.So, twenty four nonlinear equations.............

Abstract: This article deals with the usage of translucent concrete and also the advantages it brings in the field of smart construction, that it can reduce the power consumption of illumination and use the optical fibre can be made to sense the stress of structures and this concrete as an architectural purpose for good aesthetical view of the building. Translucent concrete is a concrete based material with light-trans missive properties, obtained by embedding optical fibres in it. Light is conducted through the fibre from one end to the other. This results into a certain light pattern on the other surface...............

Abstract: Coal excavating robot is the remote controlled robot can be used in mines to excavate coal with utmost efficiency and minimum human intervention. In some coal mines labour work extremely hard to shovel and load the coal in trucks in harsh temperatures, heavy work load and stressful conditions. Labour risks their health and life to do hazardous work in shoveling coal from mines. Labour life risks in coal mines can be reduced by implementing coal excavating robot in coal mines to excavate coal. Coal excavating robot has a scoop shaped heavy loader bucket in front side of robot to load the coal in mines. Loader bucket, links and Robot body frame of robot are designed in Solid works 2016 designing software..............

Abstract: Feature recognition has been always an important link between CAD and CAM. Feature recognition is applied in successive stages. Firstly, feature entities extraction should be applied, followed by an algorithm of how to relate the entities together. Finally, the feature recognition algorithm is applied. In this paper,a logic for identifying face-face interaction is applied. The type of face-face interaction is needed for further use in feature recognition. A methodology is introduced to determine the relation between faces............

Abstract: The article concerns the analysis of the impact of distributed heat storages (accumulators) type TES (Thermal Energy Storage) on the parameters of the district heating network. The simulation results show that the heat storage has a significant impact on the functioning quality of the heating system, reduces the time delay of transport and as well as minimizes heat loss during distribution process. The comparative analysis of simulation results and the data obtained from measurements confirmed the correctness of simulation studies.

Abstract: In Nigeria Road transport system is the most important means of transportation as in many developing countries. Roads are the major connecting links of states, towns, cities and villages. Nigeria has the largest road network in West Africa and second largest road network south of the Sahara with an estimated road length of 193200 kilometres. The roads have to be maintained so as to prolong its life. Without maintenance, roads can quickly fall into disrepair leading to increased costs for road users in vehicle operation, time, reliability and safety. The aim of this study is to examine the road maintenance management of Kano metropolitan roads and the possible ways of improving it...........

Abstract: Naturally convective and thermally radiative MHD Casson fluid with nano particle flow through a vertical porous plate has been studied. A flow model is established by employing the well-known boundary layer approximations. In order to obtain non-dimensional system of equations, a similarity transformation is applied on the flow model. The coupled non-linear partial differential equations are solved by explicit finite difference method and the numerical results have been calculated by Compaq Visual 6.6a. The effects of various parameters entering into the problem on velocity, temperature and concentration are shown graphically.

Abstract: Modern activities in India leads to use of plastic bags in excess. Plastic being non-biodegradable material, it takes years to decompose. Plastic bags have main constituent as poly-ethylene. The poly-ethylene when combusted produces a by-product of Carbon dioxide which leads to global warming.In this,we study the efficiency of reusing plastic waste in concrete by comparing compressive strength of concrete whose fine aggregate is partially replaced by plastic(5%,10%,15%,25%) with control concrete of M20 grade. To compensate for the strength lost due to replacement, iron fibres of diameter 1-2 mm are used in fixed amount

Abstract: Due to lack of plain terrain in Shimla, it offers sloppy terrain for construction site. Behaviour of buildings on sloppy terrain behaves different than the building on the plain terrain. Past construction practices in Shimla includes common irregularity such as soft storey, mass irregularity, torsional irregularity, unsymmetrical layout of plan, vertical irregularity and pounding. Over the past earthquakes and research papers have shown that RC buildings in sloppy terrain affects more. The present study investigates the irregularities (Table 4&5 of IS 1893 (Part-1): 2002) in the RC construction practices in hilly region (Shimla). The behaviour of (G+3) storey building with regular and irregular configurations is checked for the linear and non linear analysis based on studies that had done
