Abstract: Heat exchanger plays an important role in all the thermal applications which deals with transfer of the heat energy in different forms. Heat transfer should be optimized to get effective temperature distribution. The objective of this work is to model different segmented baffle configurations of shell and tube heat exchanger using 3D modelling and conducting thermal analysis to find the optimized model which produce effective temperature distribution using ANSYS software.

Abstract: Let G be a graph. The graceful labeling of a graph with ‘m’ vertices and ‘n’ edges is a injective function such that the induced function is given by, then the resulting edge labels are distinct. In this paper we investigate some result graceful labeling of merge graph, bistar graph, friendship graph, (graph obtained by adding a pendent edge for each vertex of the cycle, (A cycle with non-intersecting chords).

Abstract: In the era of image processing various diseases can be diagnosed automatically without any human intervention. A symptomatic disease can be recognized either of the imaging techniques such as X-Ray, CT Scan, Fundus imaging and MRI using various approaches present in the field of digital image processing. Diabetic Retinopathy is a symptomatic disease which is very dangerous because it leads to permanent blindness that cannot be cured. But routine checkup can save their vision that can be done under proper scanning and observation. It may cause due to diabetes and most of the cases pertained due to long diabetic duration. Here the proposed system is able to detect Diabetic Retinopathy automatically using Sobel edge detection technique and color mapping. Sobel is the best way to analyze the sensitive data by extracting the impairments in eyes or fundus imaging. Fundus imaging is a scanning technique for obtaining retinal image. System achieved 93% of accuracy which is bit higher than the previous works.

Abstract: In recent years, there has been a significant increase in the number of diabetic patients with diabetic retinopathy (DR). Diabetic retinopathy is the most chronic eye disease provoked by diabetes problems, which affects the eye when the blood vessels in the retina swell and fluid leaks, sometimes blocking blood flow and obstructing blood from passing through that results atypical new blood vessels grow on the retina. All of these changes gradually lead to vision loss or blindness. The intension of this paper is to review certain researches that automatically diagnose the diabetic retinopathy with different methodologies with distinct precision. In the field of medical science; it is required to diagnose the decease precisely because it may reflect the human’s lives severely.

Abstract: India has large tracts of expansive soils commonly known as black cotton soils which covers approximately 20% of the total land area of our country. These soils experience large volume changes on exposure to climates with alternate wetting and drying. Several innovative foundation techniques have been suggested to overcome the problem of expansive soils. Those techniques include sand cushion technique, cohesive non-swelling (CNS) layer technique and under reamed piles. Stabilization of expansive soil with various types of additives is the most commonly used technique. Stabilization is process of fundamentally changing the chemical properties of soft soils by adding stabilizers or binders, either in wet or dry conditions to increase the strength and stiffness of the naturally weak soils. In present investigation, the aim is to reduce swelling and shrinkage behaviour of expansive soil by improving strength and engineering properties of soil. Also, the industrial solid waste Sawdust ash is utilised for stabilisation so as to solve the problem of indiscriminate disposal. The other additive used in this study is Sodiumhydroxide. Various tests are conducted with varying proportions and results are reported.

Abstract: A common technique to optimize the performance of shell and tube heat exchangers (STHE) is by redirecting the flow within the shell side with a series of baffles. A key aspect during this technique is to know the interaction of the fluid dynamics and transfer of heat. The objective of this work is CFD analysis for flow characteristics such as back pressure, velocity, turbulence kinetic energy in various geometrical modifications of Baffles in Shell and Tube Heat Exchanger and their impact on the performance has been collected and discussed and it is found that Triple Segmented Baffles Configuration exhibits best thermal characteristics and best flow characteristics.

Abstract: In India, a marble waste powder industrial waste makes it the most suitable materials for cement-based applications. Concrete is a construction material that consists of cement (commonly Portland cement), aggregate (generally gravel and sand), water and admixtures. Cement acts as a binding material, sand acts as a void filler and coarse aggregates provide strength to the concrete mixture. For special cases to enhance or to retard the properties of the concrete mix, admixtures are added to it. This paper discusses the design of M30 concrete mix by replacing cement with marble powder accordingly in the range of 0%, 5%, 10%, 15% and 20% respectively. The comparative study of the compressive strength of all the cubed is tested and the graphs were plotted accordingly
