Volume: I , Issue: III Publication Year: 2014 , Page(s): 13-18

 

Abstract: The buildings with vertical stiffness irregularity make avery large portion of urban infrastructure. Due to accommodation ofvehicles and their movements at ground levels infill walls aregenerally avoided, which creates soft storey effect. This paperpresents an analysis of a 5-storey RC frame building with andwithout infill walls. The masonry infill walls are modelled as theequivalent diagonal strut and ‘compression only’ member. In thisstudy an attempt has been made to evaluate and critically assess theeffects of infill walls on the seismic response of 5-storey RC framebuildings. The modelling of infill walls are made using FEMA approach, Holme’s approach and Smith’s approach. The 5-storey RCframe building with open ground storey is designed using the seismiccoefficient method and the seismic demands are investigated in theforms of storey shears, storey displacements and inter-storey driftsusing time-history analysis in E-TABS 13 software.

Volume: I , Issue: III Publication Year: 2014 , Page(s): 19-21

 

Abstract: The vibratory screening machine is used in different industries like mining, pharmaceutical, food etc. In the past, the study of screening machine has been done on the basis of its design parameters like diameter of wire, length, mesh size, throwing index etc. The work regarding vibrational parameters is not widely done in the past. A little work on mathematical modeling has been done on the rectangular type vibratory screening machine. In this paper modal and harmonic analysis has been done to predict the natural frequencies of different mode shapes of the circular vibratory screening machine. This analysis can be used as the methodology for the further study of the VSM. In this dissertation work it the design and working frequencies of the screening machine are of safe region.

Volume: I , Issue: III Publication Year: 2014 , Page(s): 26-34

 

Abstract: voltage and current waveforms are preferably idealsinusoids. Nowadays popularity of electronic and other non-linearloads are increased which causes distortion in these waveforms. Thedivergence from a perfect sine wave can be represented by harmonicscomponents having a frequency that is a multiple of the fundamentalfrequency. Hence it is essential to measure the harmonic componentsto estimate their effect. The division of a variety of frequencycomponents with respect to the fundamental frequency is carried outto measure Total Harmonic Distortion (THD) which is useful tointend suitable filters to eliminate the harmonics. This paper presentsthe estimation of harmonic of different equipments in distributionsystem to improve power qualit. The 11 bus distribution system istaken as case study and harmonic distortion of different elements ofthis system is identifier using Electrical Transient Analyzer Program(ETAP) software.Keywords: Harmonics, Total Harmonic Distortion, estimation ofHarmonics, Power Quality Improvement (PQI)

Volume: I , Issue: III Publication Year: 2014 , Page(s): 35-38

 

Abstract—Arc welding is a variety of welding that usesa welding power supply to create an electric arc between anelectrode and the base material to melt the metals at the weldingpoint. Laser beam welding (LBW) is a welding method used to fixmultiple pieces of metal using of a laser. Hybrid Laser Arcwelding (HLAW) is a latest style of welding practice that joinsthe methods of laser beam welding and arc welding. The adventof combination of the laser process and the arc process,both weld penetration depth and welding speed has beenimproved. In this paper, the methodology of HLAW isdescribed. the HLAW process solves laser not only limitations ofwelding, also shows ability to produce acceptable welds in jointswith less than perfect furnish between parts. This makes weldingprocess more robust process envelope by a factor of threecompared to a conventional laser-only process.

Volume: I , Issue: III  Publication Year: 2014 , Page(s): 54-58

 

Abstract: Decolorization of different azo dyes has been studied byseveral authors but in this work, the combined treatment ofozonation followed by aerobic biodegradation has been done. Theeffect of ozonation on the degradation process of azo dyes CIReactive Black 5(RB5), CI Reactive Violet 5(RV5) has been studiedin the semi batch rector and parameters such as pH, Absorbance(atmaximum wavelength, λmax ), conductivity, COD, TOC, BOD5 weremonitored during process at different time intervals. The resultsobtained indicate that ozonation is highly effective way to removethe color of synthetic dye solutions. COD and TOC removals werehowever less complete, suggesting production of colorless ozonationby-products. Decolorization as well as reduction in COD and TOCwas found faster in mono azo reactive dye (RV5) compared to di-azoreactive dye (RB5). Ozonation increased the biodegradability of thestudied dyes, as observed by increase in BOD5/COD ratio from zeroto 0.47 and 0.49 for RB5 and RV5 respectively, after 80 minozonation. Aerobic biodegradation of these ozonated dye solutionsshowed more than 90% reduction in COD and TOC. Results of thisstudy demonstrate the potential of combined ozonation and aerobicbiodegradation for treatment of azo-dyes from economic andecological point of view.

Volume: I , Issue: III  Publication Year: 2014 , Page(s): 59-64

 

Abstract: Procedures and results of experimental work to measureTemperature distribution in electric discharge machined surfaces arepresented. In this investigation, an axisymmetric thermo-physicalFEA model for the simulation of single sparks machining duringelectrical discharge machining (EDM) process is exhibited. Thismodel has been solved using ANSYS 14.0 software. A transientthermal analysis assuming a Gaussian distribution heat source withtemperature-dependent material properties is used to investigate thetemperature distribution. The effect on significant machiningparameters (Gap current – Gap voltage) on aforesaid responses hadbeen investigated and found that the peak temperature sharplychanges with the parameters [1].The FEA model is then used to study the relation between aboveparameters and maximum temperature attended at the end of cyclewhich can be further used to find residual stress produced at the endof cooling cycle. To find residual stresses in the work piece duringEDM, the temperature distribution at the end of pulse duration inthe work piece has to be estimated [2]High residual thermal stresses are developed on the surfaces ofelectric discharge machined parts because of the high temperaturegradients generated at the gap during electrical discharge machining(EDM) in a small heat-affected zone. Because of these thermalstresses there can be micro-cracks, decrease in fatigue life andstrength and possibly catastrophic failure. The results of the analysisshow high temperature gradient zones and the regions of largestresses where, sometimes, they exceed the material yield strength.A transient thermal analysis assuming a Gaussian distribution heat scan be used to investigate the temperature distribution

Abstract: This paper investigates the different aspects of AISI 316 to increase the life of the twist drilling tool of stainless steel. No one has represented the work on modeling and modification of the tool geometry to generate the long life of twist drill of AISI 316 stainless steel. Many researchers have worked on effect produced by changing the cutting parameters as well as coating material for the same. The work has also been presented to find the Torque, Power and Thrust at the different feed, different material hardness and material factor for AISI 316 stainless steel material. Rigorous analysis is going to be carried out to decide a proper tool geometry for stainless steel tool with the help of experimental analysis and software.
