P.Asana Mustoora, A.Rameez Fathima, S.Udaya Easwari, Dr.S.Ebenezer Juliet
Abstract – Foot ulcer for diabetic patients is a major problem. In today’s healthcare systems Medical image processing plays an important role. The results of Medical Imaging procedures can be used for surgical planning and simulation, radiotherapy planning and to find the healing status of the disease. Visual assessment of diabetic wound images by physicians suffer with time consumption and also do not produce objective measurements and quantifiable parameters of the healing status. But the above mentioned problems can be solved by doing the medical image analyzes automatically using computer by applying various image segmentation methods. In this paper, Wound Image Analysis System partitions the wound image into meaningful segments using image segmentation technique in order to analyze the wound status. The aim is to accurately segment the wound region and to perform color analysis to find the healing status of wound. The image is captured and then the wound healing status is determined by applying Adaptive Mean Shift Image Segmentation followed by wound boundary determination. Experimental results show that the proposed Wound Image Analysis System minimize the frequency of health centre visit by the diabetic patients and also help to find the healing status of wound by referring the history of recently stored wound images.

5 Comparative Analysis of Compressive Strength and Stress-Strain Behaviour of Sifcon with Ferrocement
V. Prathima, Dr. T. Suresh Babu
Abstract – Concrete is a composite material composed mainly of water, aggregate, and cement. The desired physical properties of the finished material can be achieved by including additives and reinforcements in the mixture. Generally, fibres used in concrete are to control cracks, shrinkage and to reduce permeability. Fibres also shows excellent resistance towards impact and abrasion. SIFCON (slurry infiltrated fibre reinforced concrete) is one of the recently developed construction material. It is a special type of fibre reinforced concrete with high fibre content. It is a unique construction material possessing high strength, as well as large ductility and it contains excellent potential for structural applications when accidental or abnormal loads are encountered. “Ferro cement is a type of thin wall reinforced concrete, commonly constructed of hydraulic cement mortar, reinforced with closely spaced layers of continuous and relatively small size wire mesh. The mesh may be made of metallic or other suitable materials” In this project, we are using steel fibres of aspect ratio 50, steel mesh of diameter 0.62mm with spacing of 5mm. 1:1 mix was taken to cast the cylinders (30cm X 15cm). Tests were conducted on cylinders to determine compressive strengths & stress–strain behaviour. Fibres of 5%,10% & 15% were added in both parallel and random orientation. Steel mesh of 5%,10% & 15% were added in parallel manner and results are compared among those and as well as with conventional cement mortar.

10 Sulphate Attack on Blended Cement Mortar – Combination Sulphates
T.Kala Deepthi, Dr. T. Suresh Babu
Abstract – As industries are increasing day by day, so its by-products also increase. We can use these by-products in construction industry to improve certain properties of cement. Blending is the addition of supplementary cementitious materials like fly ash, ground granulated blast furnace slag (GGBS) to the cement. The resulted cement mortar is known as BLENDED CEMENT MORTOR. This will have improved qualities like strength, workability, durability. Ca(OH)2of hydrated cement paste reacts with sulphate ions and forms Calcium Sulphate, which further reacts with C3A to produce ettringite. This is known as SULPHATE ATTACK. Sulphate attack can be either ‘external’ or ‘internal’. External: Due to penetration of sulphates in solution, in groundwater for example, into the concrete from outside. Internal: Due to a soluble source being incorporated into the concrete at the time of mixing. Examples include the use of sulphate-rich aggregate, excess of added gypsum in the cement or contamination. Properties like strength and weight of sulphate attacked cement mortar differs from the normal conventional cement mortar. Here we make an attempt to find out these changes.

12 The Fog Computing Paradigm
Pankaj Sareen, Parveen Kumar
Abstract – Cloud computing is a delivery platform which promises a new way of accessing and storing personal as well as business information. It provides resources to its users through the Internet. But it also has a risk that is the involvement of a third party which makes it difficult to trust that user data is secure enough and will not be misused. To provide security, new technology called Fog computing. Fog computing, also termed edge computing, can address those problems by providing elastic resources and services to end users at the edge of network, while cloud computing are more about providing resources distributed in the core network. Fog computing extends cloud computing by providing virtualized resources and engaged location-based services to the edge of the mobile networks so as to better serve mobile traffics. Therefore, Fog computing is a lubricant of the combination of cloud computing and mobile applications.

Komal Rawat, Hina Akhtar, Anirudh Gupta, Ravi Kumar
Abstract – In the present paper 2D CFD model of H-Darrieus Wind Turbine has been developed. The model was implemented in ANSYS Fluent solver to predict wind turbines performance and optimize its geometry. As the RANS Turbulence Modeling plays a strategic role for the prediction of the flow field around wind turbines, different Turbulence Models were tested. The results demonstrate the good capabilities of the Transition SST turbulence model compared to the classical fully turbulent models. The computational domain was structured with a rotating ring mesh and the unsteady solver was used to capture the dynamic stall phenomena and unsteady rotational effects. Both grid and time step were optimized to reach independent solutions. Particularly a high quality 2D mesh was obtained using the ANSYS Meshing tool while a Sliding Mesh Model was used to simulate rotation. .Coefficient of lift and drag were calculated at different values of attack. Main parameter that is monitored in this study is the Tip Speed Ratio (TSR) . Thus, an optimum value of TSR is obtained at which the turbine gives maximum power.
18 Modulated Intensity Gradient and Texture Gradient Based Image Segmentation
Monika Patel, Megha Soni
Abstract – Image segmentation is currently a prominent topic for both military and commercial researchers. This paper concentrates on the image segmentation based on the combination of modulated intensity gradient and texture gradient. Image segmentation is an integral part of image analysis. In image processing different processes are done on images to enhance it at different parameters. These processes are not directly applied on images but before that it needs to be segmented or divided in smaller parts called pixels or small blocks of pixels. So segmentation becomes an integral and basic part in image analysis and error at this stage can influence other processing techniques. The performance of this method is compared with the available techniques. The proposed system improves the Mean Square Error (MSE), Maximum Error (MAXERR) and Peak Signal to Noise Ratio (PSNR).

20 A Comparative Study between Reactive Powder Concrete and High Performance Concrete
L.Jaya, Sumanth Doodala, Dr.T.Suresh Babu
Abstract – Reactive Powder Concrete (RPC) is composed of very fine powders (cement, sand, and silica fume), steel fibres (optional) and superplasticizer. A very dense matrix is achieved, and this compactness gives RPC ultra-high strength and durability properties. A comparison of the physical, mechanical and durability properties of RPC and high performance concrete (HPC) shows that RPC possesses better (Both compressive and flexural strength) results compared to HPC. HPC leads the way to achievement of the maximum compressive strength of the order say 120-150 Mpa or so. However, at such a level of strength, the coarse aggregate becomes the weakest link in concrete. In order to increase the compressive strength of concrete even further, the only way is to remove coarse aggregate. This philosophy has been employed in what today known as Reactive powder concrete. The principal objective of this study is to compare mechanical and durable properties of M60 grade High performance concrete with RPC120. In the present study, performance of reactive powder concrete without quartz powder and containing silicafume as a replacement for cement and High performance concrete M60 grade with silicafume as as admixture at the varying percentage of 0%, 5%, 10% , 15% and 20% by each is investigated. To compare the results of cement replaced mixture, specimens without cement replacement are also casted. Performance of the various mixes is tested by the Compressive strength, Flexure strength and Tensile strength. The results show improvement in compressive strength, flexural strength and Tensile strength in cement replaced mixes in Reactive powder concrete.

K.Sudhapriya, S.Preethi, M.Ejas Ahamed
Abstract – Small and medium scale solar photovoltaic inverters are interconnecting to the low voltage distribution system at a rapid growth. The grid connected solar photovoltaic inverters able to provide the reactive power to the low voltage distribution system. Reactive power capability of the solar photovoltaic inverter is depending upon the inverter’s rating and the solar power generation. In this project focuses on the reactive power management for solar photovoltaic (PV) inverter in low voltage distribution system. This strategy can be applied for various solar power generating conditions (no solar power generation, low solar power generation, maximum solar power generation, cloud passing solar power generation). During no and low solar power generation, the inverter inject reactive power and support the voltage by using Dynamic VAR compensation mode. During maximum solar power generation, the inverter absorbs reactive power and there by mitigating voltage rise using Droop characteristics approach. During passing clouds, the inverter will inject reactive power and reduce the voltage fluctuation using Ramp rate control. The objective of the project is to maintain the constant voltage level and to provide the fast reactive power control in low voltage distribution system. The power system model conveyed in the project is established on the MATLAB / SIMULINK R 2009 b platform. The results show that the solar photovoltaic inverter can be used for reducing the voltage rise, voltage fluctuation and improve the voltage profile in various solar power generating conditions.
22 Pulse Charging Method for Electric Vehicles and Renewable Energy Applications
M.Ejas Ahamed, R.Ramya, K.Indirajith
Abstract – High Capacity Li-ion and Pub-acid batteries are broadly used in present Renewable Energy and EV applications. Consequently, charging these batteries in a minimum amount of time while maintaining efficiency is crucial. The need for fast charging has carried up the method of Pulse Charging. However, present pulse charging method which involves hard- switching, pose difficulties due to switching losses in the semiconductor devices. This paper represents a Fast Pulse Charging mechanism for High Capacity Pub-acid and Li-ion Batteries which minimize switching losses by Soft Switching. The operation of the methodology is concentrated on the Fully Clamped Quasi-resonant DC Link Converter which usefully generates current pulses to charge the battery in both between Constant Current (CC) and Constant Voltage (CV) phases. Switching losses are minimized by manipulating Zero Current Switching (ZCS), and the simulated results show that this can be achieved for higher switching frequencies further minimizing the circuit size. Experiments were conceded out by the research group for both conventional CC-CV method and for current pulse charging method. The results declared that proposed methodology reduces the charging time of Pub-acid batteries by 14.01% in comparison to the conventional CC-CV charging method.

25 Comparison of Flexural, Split Tensile & Compressive Strength of HP-SCC using Magnetized Water
Sandesh Jadhav, Rahul S Patil
Abstract – The objective of the report is to plot an effective trend between the strengths of concrete viz. Flexural, Split Tensile & Compressive Strength of HP – SCC Concrete. This will help us understand the exact relation between the three different strengths of the material thereby forecasting & modifying the design phenomenon. Systematic testing of the raw materials, the fresh concrete and the hardened concrete is an inseparable part of any quality control programme for concrete which helps to achieve higher efficiency of the materials used and greater assurance of the performance of the concrete in regard to both strength and durability. Concrete has relatively high compressive strength,but significantly lower tensile strength,and as such is usually reinforced with materials that are in tension(often steel).The elasticity of concrete is relatively constant at low stress levels but starts decreasing at higher stress levels as matrix cracking develops. Concrete would almost always fail from tensile stresses,even when loaded in compression .the practical implication of this is concrete elements subjected to tensile stresses must be reinforced with material that are strong in tension. Reinforced concrete is the most common form of concrete.
26 Decision Based Algorithm for the Removal of High Density Salt and Pepper Noise in Images and Videos
S.Dinesh Krishnan, R.Manoj Kumar
Abstract – A Decision based algorithm for high-density salt and pepper noise removal in images and videos are proposed. The existing non-linear filter like Standard Median Filter, Adaptive Median Filter shows better results at low and medium noise densities. At high noise densities, their performance is poor. Decision based algorithm to remove high-density salt and pepper noise using sheer sorting algorithm is proposed. Results of the algorithm is compared with various existing algorithms and it is proved that the new method has better visual appearance and quantitative measures at higher noise densities as high as 90%. The proposed system works efficient with both Grey scale and coloured images. Divide the image into 3*3 blocks but the image should be in 255*255. By using shear sorting algorithm we will arrange in ascending order and remove the noise by getting the values of 0 and 255. A graph has been displayed to show the result when the noise has been added to image of 10 to 90% and removing the noise. The second phase has been tried the same with Video files which have been converted as frames. The noises at various densities have been applied to the frames. The PSNR and MSE values have been calculated and displayed in graph. Both image and video files have been demonstrated and the quality measures plotted.
