Abstract: Image inpainting was historically done manually bypainters for removing defect from paintings and photographs. It isthe art of filling in missing data in an image. The purpose ofinpainting is to reconstruct missing region in a visually plausiblemanner so that it seems reasonable to the human eye. In Imageinpainting region filling of missing information from a signal usingsurrounding information and re-form signal is the basic work ofinpainting algorithms. Inpainting refers to the art of restoring lostparts of image and reconstructing them based on the backgroundinformation. There have been several approaches proposed for thesame. Here, an algorithm is based on the exemplar based proposedto implement adaptive image inpainting algorithm. A algorithmautomatically inpaint the selected area according to the backgroundinformation. The image can then be saved. The algorithm isimplemented in the software tool MATLAB, present exemplar basedalgorithm will be modified by changing values of variable andadaptively using fminsearch algorithm.

Priti Bhanushali, Prof. N. M. Patel

Volume: I , Issue: III  Publication Year: 2014 , Page(s): 129-132

 

Abstract: Pressure swing adsorption (PSA) is a very versatiletechnology for separation and purification of gas mixtures. Ascompared to conventional cryogenic distillation technique, PSA isless hazardous and economical technique. The general model isdiscussed to separate gases such as nitrogen, oxygen, hydrogen,carbon dioxide from the air with the use of an adsorbent forisothermal process.Detailed model is developed for Skarstromcycle. The model is developed to get oxygen product from the airwith the use of zeolite 13X as an adsorbent. In this model, manyequations are there like partial differential equation, algebraicequation etc. Numerical method is adopted to solve partialdifferential equation. Partial differential equations are converted toordinary differential equation by OCFE (Orthogonal Collocationon Finite Elements) method. This ODE’s are solved by differentsolver in Scilab. This model can predict the percentage recoveryand purity of product gas. The results obtained from this modelwill be compared with available literature data.

Volume: I , Issue: III  Publication Year: 2014 , Page(s): 137-142

 

Abstract: The modern approach to earthquake resistant design isPerformance Based Seismic Engineering. To cover intricate rangeof issues faced by structural engineers it is extended over a limitstatebased design approach. As compared to beam-column inconventional slab, flat slab and prestressed flat slab diaphragms arebecoming popular and gaining importance because of free design ofspace, shorter construction time, and architectural –functional andeconomical aspects. It is important to study response of flat slabsand prestressed flat slab under seismic conditions because they maynot have been designed for seismic forces. We have figured out theresults obtained by performing push over analysis on conventionalbeam slab, flat slab and prestressed flat slab by using softwarepackage SAP2000 in this paper. An irregular C - shaped buildingframe with (G+5) storeys having 6 bays in X direction and 4 bays inY direction is considered for analysis. The results from the analysisfor all the diaphragms which is presented in the paper shows thatshear bearing capacity of the building decreases when flat slab andprestressed flat slabs are used in place of conventional beam slabdiaphragm.

Suman M. Sharma, Mayur G. Vanza

Volume: I , Issue: III  Publication Year: 2014 , Page(s): 143-149

 

Abstract: The common practice to design the foundation isto provide, first the shallow foundation such as isolatedfooting or raft to support structure and if this is not adequatethen deep foundation like piled foundation. At places whereclay deposit are of larger thickness, and if it possessessufficient strength (qu>100 KN/m), raft foundation can beemployed. If the foundation has a very poor strength (qu=0to 25 KN/m²), purely pile foundation will prove to be a betteroption. But if the clay deposit has an intermediate strength(qu=50 to 100 KN/m²), the only option available is piled-raftfoundation which is economical since the piles help inreducing settlements and the raft provides an ample bearingcapacity as well as resistance to differential settlements. Thuspiled-raft is a good alternative at places where more totalsettlements are permissible for the structure along with aconsiderable bearing capacity. In this paper the choicebetween a piled raft and beam & slab raft foundation dependsupon the soil properties and the weight of the building. In thispaper, study is carried out for comparison of “Piled Raftfoundation” and “Beam & Slab Raft foundation”. In this paperanalysis and design of economical foundation for high risebuilding has been done considering both geotechnical andstructural design aspect. Quantitative study has been carriedout for different values of Soil Bearing Capacity. Based onthis study we conclude that for given bearing capacity like 125KN/m2, 150 KN/m2, and 180 KN/m2) Piled Raft foundation isfound most safe and economical rather than Beam & Slab Raftfoundation.

Volume: I , Issue: III  Publication Year: 2014 , Page(s): 154-157

 

Abstract: Earthquake is a force which cannot be neglected during the design of the building. The performance of building is tested during the massive earthquake only. After a massive earthquake, the destruction is very huge which can't be bearable. To overcome this issues, some complex designs are introduced in the structural design field. This paper contains the design of Reduced Beam Section (RBS). In this design, the area of flange is reduced by giving it shape or drilling holes. The shapes may be of circular, tapered or straight cut. In this paper,a beam is taken whose flange is cut in straight shape by calculations and the creation of plastic hinge with the help of FEMA 350. The simulation of the design is done in ANSYS software with all relative constraints and to get the equivalent stress, equivalent strain and total deformation.

Abstract: The synthetic textile waste materials and unused cottonstalk is available in abundant amount in an India. The study is basedon utilization of both this waste materials in wood based composites.Because if we recycled the synthetic textile materials likepolypropylene, polyvinyl chloride, polyethylene, etc. which ispossible to use by replacing the virgin polymers used in wood basedcomposites materials and also as the cotton stalk is having somewhatsimilar properties like hardwood, which also can be utilized as byreplacing the wood flour content in wood based composites. In thisstudy the experimental composites are produced as per similarcontents in exiting commercial wood plastic composites (WPCs).Oneis made up of Wood flour and Polyvinyl chloride (WPVC) and otheris made up of Wood flour and Polypropylene (WPP). Then thesamples of all composites (Commercial and Experimental) wereevaluated by their physical and mechanical properties. The resultsshows that’s the experimental composites gives the slightly more orless physical and mechanical properties compared to existingcommercial composites. Hence from this study it is conclude that wecan use these abundantly available waste materials in wood basedcomposites. Which is gives the new alternative materials to thecomposites industries at less comparative cost than existing rawmaterials of composites industries. This is beneficial to decreasingthe cost of existing wood based composites materials.
