The major objective of this project is to designing a quadcopter which can be controlled by hand glove. The control of a quadcopter can be made by the movement of hand, which in turn maneuvers the quadcopter through radio transmission, fully with the hand. The basic step is to designing and fabricating a quadcopter with accurate flight characteristics. This in turn continued by the assembly of various electronic units on a single right hand glove for the hand movement control. This quadcopter can be controlled both by normal radio control and by hand. This type of quadcopter can able to fly approximately a radial distance of about 1 km.

In recent years of technological perspective, the pressure distribution of airfoil has come to be a
wide extent of studies using experimental, theoretical and computational code solving methods. In this
hierarchy, it is more predominant to calculate the value of pressure distribution directly from the airfoil without
any mode of additional requirement of experimental or computational one. In this paper, we present the method
of plotting the NACA 4 digit airfoil and pressure distribution around it at zero degree angle of attack. The
obtained results are compared and contrasted with experimental and computational calculations. The empirical
formula of Cp is given and calculated for NACA 4 digit airfoil and MATLAB codes.
Keywords: - NACA 4 digit, pressure distribution formula, MATLAB codes, etc.

Abatement of emissions from transport sector is one of the major concerns throughout the globe. One of the technical challenges in transportation sector is to reduce emissions from diesel engine and simultaneously to meet the satisfactory performance; hence Dual fuel engines are most attractive due to its lower emission levels in comparison with the conventional diesel engine particularly at full loads. However based on my studies of distinct conclusion of authors, it is required to study the dual fuel combustion process with more information at part loads due to the poor performance and high CO and UHC emissions at these conditions. It is found that at part loads, areas that are influenced by diesel diffusion flames are ignited and premixed charge flame could not propagate properly as the combustion process is slow and leads the heat release to be drawn more towards the expansion stroke which causes incomplete combustion and consequently high amount of UHC and CO will be emitted..............

Slot milling is one of the complex metal cutting process which is to be investigated to make it cost effective and to improve the quality of the machined components by reducing or eliminating the machining induced damages. Hence, in this research work a realistic 3D Finite Element Model is developed in ABAQUS\Explicit to simulate the slot milling process. The Finite Element Model consists of real 3D shape of the tool and workpiece. Slot milling simulation is carried out under different spindle speeds and feeds. The cutting forces, stress and chip formation are predicted from the Finite Element simulation. Moreover, the cutting force profile and data are compared with the experimental results available from the literature and found to be in good agreement. The proposed FE model with the Johnson – cook failure criteria predicts the Cutting forces, Chip formation, stress and the stain rate very effectively. The results obtained from the FE model confirm the quality and capability of predicting good results.

Construction is project based where different parties work together to achieve a common goal. The means of achieving this goal is fraught with hazards. In that major hazard is considered as electrical hazards. Electrical hazard is therefore a phenomenon or a process that can endanger construction worker and their environment. Consequently the study assessed the level of electrical hazard and safety measures awareness among electricity users in construction area.

Nowadays various researches achieved the strength of the concrete; the exposure on quarry dust plays a vital role in the field of construction. Concrete is the commonly used material in the construction industry. The widely used raw material in the concrete are cement, fine aggregate, coarse aggregate and water. River sand is at great rate of depletion and expansive, due to which there was a need for an effective alternative. Quarry dust, has been found as an economic alternative for sand. In fact we need high strength concrete to withstand to the heavy loads in a building.In this paper, we have investigated the study of quarry rock dust as partial replacement of fine aggregate in concrete...........

The term floating column is a vertical member which ends at its lower level rests on a beam which is a horizontal member. The beams in turns transfer the load to other column below it. In present scenario buildings with floating column is a typical feature in the modern multistory construction in India. Such features are highly undesirable in building built in seismically active areas. In the unavoidable circumstance floating columns are adopted in building. Brief analysis will be made for the structure with and without floating column. Floating columns are placed different story levels and different position in the structure, for different seismic excitation by changing the frequency of vibration using ETABS standard Finite element analysis package. Final results for maximum story displacement, maximum inter-story drift, story base shear, overturning moment are compared with different seismic excitation. The most safer and economical method to reduce the cost of floating column beam is suggested..
Keywords - Dynamic Loading, ETABS, Finite Element model, Floating column, Seismic analysis.

Low cost or affordable construction technologies and materials are always in the ever growing demand for rapid housing delivery in developing economies like India. From the global trends in rural to urban migration, most of the developing countries are facing an enormous service backlog and massive delivery challenges in addressing its millennium development goals in the provision of housing and shelter. With growing concern over global warming and climate change, global responsibility in the consumption and production of renewable energy becomes not only a vital necessity, but a moral imperative also. This has imposed a thrust towards the use of eco-friendly materials and sustainable architecture in both developed and developing countries. This paper focused on some of the ecofriendly materials used for construction industries with low cost.
