1 A Survey on Various Segmentation Methods in Medical Imaging
J.Ruby Elizabeth, S.Ebenezer Juliet
Abstract - Medical imaging is a process to view the internal parts of the body for analyzing the clinical conditions. Medical imaging is used to diagnose, monitor, or treat medical conditions. In order to retrieve the accurate information from medical images segmentation is needed. Image segmentation is a process in which a single digital image is divided into multiple images as a segment. Medical images should be segmented accurately for detecting various diseases. In segmentation, images are simplified or the image's representation are changed, so that it is easier to analyze the possible diseases. Segmentation can also easily detect the affected or injured area and it also act as a key step for the effectiveness of the treatment given to the particular patient. The various segmentation methods are given in this paper.
2 Effect of Salt Water on Compressive Strength, Flexural Strength & Durability of Concrete
Abhishek Patel, Anubhav Rai, Vedant shrivastava
Abstract - In this research, the effect of salt water on the compressive strength, flexural strength& durability of concrete was investigated. This paper therefore presents the result and findings of an experimental research on the effect of salt water on compressive strength, flexural strength& durability of concrete. For this concrete cubes &beams were cast with fresh water and salt water for a design mix of M-30 1:1.84:3.39 by weight of concrete, and 0.45 water- cement ratio. Half of concrete cubes and beams were cast and cured with fresh water and remaining half cubes were cast and cured with salt water. The concrete cubes were cured for 7,14 and 28 days respectively. The result of the average compressive strength, flexural strength of concrete obtained using fresh water ranges from 27.20 - 39.80N/mm2 and 4.64-5.37MPa and using salt water ranges from 28.65 41.6N/mm2 and 4.73-5.49MPa .Salt water concrete is less durable than portable water concrete
3 Experimental Study on Mechanical Properties of Waste Concrete Powder and Coconut Shell Ash
G. Pandeeswari, G.R. Seenivasan, V. Nandakumar
Abstract - Use of waste concrete powder and coconut shell ash in concrete provides an encouraging solution to the problem of waste material management. Based on the survey of production and usage of waste concrete powder in Recycled concrete and the properties of this waste concrete powder is clear and that the concrete can be used in low economical cost. Waste concrete can be used for making normal structural concrete with the addition of some admixtures like fly ash, silica fume and waste materials. The main objective is to determine the compressive strength and tensile strength of concrete by varying the percentage ratio of waste concrete powder and coconut shell ash as cement. The use of waste concrete powder does not affect the strength of concrete. For each ratio, three cube specimens and three cylinder specimens are casted and cured. The specimens are cured in water at 7days, 14days and 28days respectively. The mechanical properties are determined such as compressive strength, tensile strength. The waste concrete powder and coconut shell ash are replaced as cement with varying proportions. For each mix preparation, specimens are casted and cured for 7days, 14days and 28days in water and the mechanical properties (compressive strength and tensile strength) were determined.
