Abstract: In the present study a hybrid GA-ANN based model has been developed for the prediction of Surface Roughness obtained in a conventional turning process. Surface roughness is a very important property of a machined part and is hard to predict due to the complex nature of turning process. Artificial neural networks are intelligent tools, capable of modeling complex non-linear relationships by simulating the working process of a nervous system. Genetic Algorithm is a powerful and efficient global optimization method. These two tools are coupled in the present study to accurately model turning process. A significant improvement in predicted values is observed in comparison to a simple ANN model.

Keywords: Artificial Neural Networks, Genetic Algorithms, MATLAB, Surface Roughness, Turning.

Abstract: Concrete is most widely used construction material in the world next to water. It is estimated that every day around 3km3 of concrete is cast globally. Besides, manufacture of cement is highly energy intensive, consumes voluminous natural resources and causes environmental health hazards. In addition, it produces considerable amount of green-house gases like CO2. Apparently, this is the cause of concern among the researchers global-wide regarding cement, which is impelling them to develop alternate materials that could replace cement completely...........

Abstract: Electro-kinetic treatment has been recognized as a promising technology for different purposes in both civil and environmental engineering. The main focus of this study is to improve the durability of cement concrete by application of electro-kinetic method.This method can be used mainly in pre-cast, pre-stressed and reinforced concrete members like railway sleepers, girders and other precast and prefabricated structural elements. Durability of structures is of global concern, many engineers and researchers are working to enhance durability of concrete elements.The durability of concrete can be improved by pore filling effect by ionic migration by adopting electro-kinetic concepts.

Abstract: Underwater concreting is one of the oldest methods of placing concrete under the water for the construction of submerged structures like harbors, bridges, aqueducts and other similar structures. From the literatures, it is found that very few works has been done for promoting the underwater concrete (UWC) at present scenario. There is a global need for preparing the UWC which should have properties to suit the current requirements to withstand environmental needs, strength, anti-washout properties, quick setting and also to have bonding properties with existing old concretes for the repairing purposes..........

Abstract: As the concept of SCC and conventional concrete is different, traditional models cannot be extrapolated without any verification in SCC, however the matrix shows a very high filler content, much higher than in traditional concrete. Although self- compacting concrete (SCC) is currently used in many countries, there is a fundamental lack of the intrinsic durability of the material itself. It is widely reported that self-compacting concrete mixtures usually show improved durability characteristics as compared with normally vibrated concretes. In the current era, the present day world has witnessed a phenomenal rise in construction activities over decades. The demolition of existing old structures inevitably results into the generation of construction and demolition (C&D) waste, the disposal of which is a problem causing environmental hazards. The main target of this research is the evaluation of the durability properties and pore structure studies of medium strength self-compacting concretes with recycled aggregates and their comparison with those measured on reference normally vibrated concretes...........

Abstract: Ground water is considered as primary source of water for construction usage. Due to deep excavation and higher water level many times, the availability of water is quite more than the requirement for construction purpose which results in huge wastage of water. It initiates proper analysis of water availability and its management for other purpose to cope up with a current water requirement. There should be proper water management system considering improved reusability aspects............

Abstract: Devarayapuram and surrounding villages situated at the foot of Western Ghats, about 20 km west of Coimbatore is mainly depending upon Agriculture. Dry crop farming is the only source for the people in these areas, as there is no perennial water source. The Noyyal River which flows eastwards from the Western Ghats, feeds the lands on the southern banks and a small area on the upper reaches. The geological formation of this area also does not permit this river to feed the lands between foot of perumalmudi hills and the north bank of the river. The people in these areas are mainly depending upon the dry farm cultivation only and a farmer...........

Abstract: Wind has been used as a source of energy since the early middle ages. Initially, windmills were used for mechanical purposes such as the milling of grain and the pumping of water. The modern wind turbine however converts the energy extracted from the wind to electrical power which can be used elsewhere. There are different types of foundation in different water depth for offshore wind turbine. Generally in India, production of wind power plant has not yet established. In this study, a location at West Cost of India has been selected...........

Abstract: In this paper a materially damped linear homogeneous beam-like equation has been considered. The viscoelastic beam is simply supported at both ends, whereas general initial conditions are considered. From mechanical and physical point of view the problem describes a mathematical model of internally damped transversal vibrations of a moving conveyor belt or a viscoelastic chain drive. From Hamilton's principle, a fifth order partial differential equation (PDE) for axially moving continuum has been formulated. The axial speed of the beam is considered to be positive..........

Abstract: The purpose study will discover the evident analysis of one humped dromedary foot. The analysis influences in finding sand of the camel sole in slipper regions that would support in discovery of footpad and foot syndromes. Behaviour of sole pad penetration into sand was predicted on camel's fore and rear feet using computed technique, for the corresponding segments at the same weights and speeds and for their selected distinctiveness. Camel walk's and his ordinary steps and increase speed to travel and cut off roads and deserts with the magnitude of the weights have a direct impact on the camel feet and stretch the pads, which requires the study of the case and shape of these feet-pads,...........

Abstract: Proper quantification and characterization are essential for successful solid waste management. Proper segregation, collection, recovery and systematic disposal are very rarely followed in India, particularly in rural areas. Solid waste management in Mylavaram, a Panchayat in Krishna district, AP is considered in the present study and examined the scope for improvement. Presently, there is no proper implementation of solid waste management practises in Mylavaram except for collection of solid wastes and dumping in two sites outside Mylavaram. Systematic studies are conducted in Mylavaram...........
