Abstract

Segmentation is basic process in image processing. It always produces an effective result for next process. In this paper, we proposed the flower image segmentation. Oxford flower collection is used for segmentation.Different segmentation techniques are available. Different techniques and algorithm are developed to describe the segmentation.We proposed a OTSU thresholding technique for flower image segmentation in this paper. which gives good result as compared with the other methods and simple also.Segmentation subdivide the image into different parts.firstly, segmentation techniques and then otsu thresholding method described in this paper.CIE L*a*b color space is used in thresholding for better results.Thresholding apply seperatly on each L, a and b component. accordingly the features can be extracted like shape, color, texture etc. finally, results with the flower images are shown.

Keywords: Otsu thresholding, segmentation, CIE Lab color space, Region based segmentation, globle thresholding method.

Abstract

Construction of tall buildings, both residential and commercial are in insistance. In case of tall structure high lateral forces develops due to earthquake load and wind load are crucial. Thus the effects of lateral loads needs consideration for strength and stability of the structures. In tall buildings, lateral loads are critical as it increases drastically after a certain height of the structure. Shear wall systems are one of the most commonly used dynamic load resisting systems in high-rise buildings which help in achieving strength and stability along with economy. In this study, an attempt has been carried out to check the dynamic stability of a tall residential structure by applying variations symmetric arrangement of the shear wall. The Case study of a 26 storied RCC structure situated in Pune region of Maharashtra, India has been carried out. The effect of location of shear wall on dynamic behaviour of building is analysed using ETABS software using response spectrum method for earthquake analysis and IS875 (III) for wind analysis. The proposed position of shear wall gives the effective results as compare to other position.

Keywords: Dynamic stability, RCC building, Shear wall, Tall structures, Lateral forces, Response spectrum method, wind analysis, IS 875(III)

India
Paper Indexed : : 03.3005/xxxxxxx
International Journal of Computational Engineering Resaerch, Volume 06 ~ Issue 05 (May 2016)

Abstract

The paper is about the process improvement in the assembly line at switch manufacturing company and to improve the process by focusing into the areas viz. Process flow, Time study and rework minimization. This improvement are made by using cause-and-effect diagram, critical path method and root cause analysis. The analysis will help to reduce the amount of rework that occurs during manufacturing of modular switches in the assembly line process.

Abstract

Ride comfortability of vehicle is a big challenge for the automotive industries and de sign engineers. The suspension system is the major source of providing comfortability by absorbing vertical vibrations. This paper presents modeling of the non - linear semi - active suspension system equipped with Magneto Rheological damper. Simulation of the designed model is performed in Simulink. A comparative analysis of the Simulink response shows the difference between linear and non - linear model. It has also shown that fuzzy logic controller has improved the performance of the system.

Abstract

This paper deals with the design of the tool Entitled Database Migration Tool Across Standard Database Formats processing data migration between different relational database management systems (RDBMS).The Database Migration Tool Across Standard Database Formats entitled is mainly aimed at designing a tool to handle for migrating one database from a sources of data to another,changing database's schema if necessary. Paper also proposes methodological guidelines for successful migration of database tables and their data between different RDBMS and suggests the possibility of tool extension when the source or target RDBMS is changed. The proposed tool is shown on data migration of selected database of the source RDBMS to the target RDBMS

Keywords: Database Migration Tool, RDBMS, Migration, ETL, Oracle, MySQL, MS ACCESS, Database format.

International Journal of Computational Engineering Resaerch, Volume 06 ~ Issue 05 (May 2016)

Abstract

Numerical modelling of condensation had been a challenging task for the researchers for many years due to its time scale and rapidity. Present work deals with the characterization of condensation in presence of non-condensable gases on isothermal surfaces which is a common situation in many condensing devices. The investigation includes the effect of different flow parameters on condensation of saturated steam-air mixture using a numerical approach. The study uses wall condensation model through ANSYS CFX solver. The effect of mass fraction of steam, operating pressure and mass flow rate of mixture is studied. Investigation provides some key characteristics about film condensation which normally remain absent in condensation without non-condensable gas. The findings of this study will provide valuable insight in thermal design process of components incorporating this phenomenon.

Abstract

To increase efficiency, reduce emissions, cost and to reduce weight of boiler per MW, the power manufacturing sectors are going towards the once through technology (super critical boiler) instead of sub- critical. Once through supercritical (OTSC) technology has become a focal point for effective utilization of coal-based thermal power generation sector in India. Another main advantage of moving towards OTSC technology is reducing the weight of the boiler per MW, which can be done by going for material capable of handling higher pressure and temperature than the conventional material.......
