Volume: I , Issue: III Publication Year: 2014 , Page(s): 68-71

 

Abstract: Fly ash based concrete has a disadvantage of low initial(28 days) compressive strength , over an advantage of highdurability .although this loss of compressive strength is achievedafter 90 days, it requires continuous curing. As Glass fiber basedconcrete has an advantage of very high initial compressive strength,it can be added to fly ash based concrete to conquer its disadvantage.This paper deals with experimental study of strength & durabilityaspect of fly ash based woven roving glass fiber reinforced concrete.For this Investigations were carried out for workability, compressivestrength and durability properties such as water absorption, acidicacid and alkalinity measurement of M25 grade of fly ash basedconcrete mixes with different percentage of woven rowing glassfiber with 25 % replacement as fly ash and 0.1 %, 0.2 % , 0.3 %addition of woven roving glass fiber .the experiments were carriedout for two w/c ratio viz 0.45, 0.5. Experimental results show thatincreasing quantity of glass fiber decrease the workability ofconcrete. 0.2 % addition of woven roving glass fiber with a w/c ratio0.45 gives the optimum result for both strength & durability of M25grade of concrete.

Abstract: This paper presents a brief description of Automatic BarbedWire Making Machine Bwm-700, its modification and designalterations. This machine serves as a development to manuallyhandled barbed wire maker and semi-automatic which were used tomanufacture barbed wires presently available in India. Also BWM-700 capabilities are enhanced to make unloading of wire coil safe andaccurate with respect to weight.BWM-700 has several sub-assemblieseach is associated with some portion of the function of producingfinal wire. There are mechanisms for drawing main wire andauxiliary wire, attaching barbs to the main wire, cutting the accuratelength of barbs, advancing the wire horizontally and finally rolling itover the cage and unloading it. This all units obtains power from thesingle source i.e. 3 phase motor. This machine was not having facilityfor doing any kind of alteration in wire and twisting and turningwhich are the basic operation that is associated to it were lackinguniformity. The final produced wire was also not rolled and packagedproperly and hence spool with fingers was attached to cage assembly.Moreover it also calls for certain accessories like line switches,contactors and length counters being added which will enhance itscapabilities like measuring length of wire coil, stopping cageassembly to unload the coil.

Abstract: To manage the increasing amount of video information, avideo scene change detection method is essential. Many advancedvideo applications require the scene change detection to organize thevideo content. In our paper we are going to implement an effectivescene change detection method using an unsupervised algorithm withthe help of the technique of object tracking. By using this method weare going to perform not only accurate scene change detection, butalso acquire information of the video frames, which is very useful forvideo data indexing, clustering and analysis. We are going to detectmoving objects in colour image sequences. A video stream isprocessed at various levels by comparing the consecutive frames. Thesystem successfully extracts changes from dynamic imagessequences.In our system, we first parse a video sequence into physical shots anddetect changes. According to changes the clustering algorithm willmerge shots into groups. By integrating the video knowledge in theindexing structure, the database system will make more sense insupporting the retrieval and browsing for users. We first present aknowledge-based video indexing and content management for videoinspection system.

Volume: I , Issue: III  Publication Year: 2014 , Page(s): 112-114

 

Abstract: The Infrastructure Sector is one of the fastest growingsectors. The Public private partnership mode has been playing acentric role in the development of this sector in India. Roads are themost requisite part of infrastructure for providing industry andagriculture with the connectivity to markets and more important forimproving the quality of life of citizens. PPP Model gainedimportance in all infrastrure related projects, but the model nowadaysfollow problems from the both side – Public and also from privateplayers. Public frequently agitated to toll booth on the hike of tollrates and due to risk many private companies reluctant to invest inPPP base road project.The Toll Policy was formed in 1997 – After that there is no majorchange in policy; though Country, Infrastructure sector and alsoeconomy had face many changes. Toll Revision policy amended in2008 but with minor changes. After the study – we feel that there isneed to do some changes in toll revision policy. Toll revision policyshould be such that it decreases the risk from private party and alsomake users satisfied with toll rates.
