SIFT: Scale Invariant Feature Transform (Review)
This paper presents a study on SIFT (Scale Invariant Feature transform) which is a method for extracting distinctive invariant features from images that can be used to perform reliable matching between different views of an object or scene. The features are invariant to image scaling, translation, and rotation, and partially invariant to illumination changes and affine or 3D projection. There are various applications of SIFT that includes object recognition, robotic mapping and navigation, image stitching, 3D modeling, gesture recognition, video tracking, individual identification of wildlife and match moving.

Significance of OSPF Routing Protocol in Mobile Ad Hoc NETworks (MANET)
Mobile Ad Hoc Network (MANET) is collection of multi-hop wireless mobile nodes that can communicate with each other without centralized control or established infrastructure. The network in which wireless links are highly error prone and can go down frequently due to mobility of nodes, interference and less infrastructure. Routing in MANET is a quite difficult due to highly dynamic environment. Several routing protocols have been proposed for mobile ad hoc networks. This paper proposed OSPF routing protocol in Mobile Ad Hoc Network. Here, the router first find out the shortest path from source to destination and forwarded the packet in that path.

Hard Faced Layer on Mild Steel Made by Paste Technique with Smaw Electrode to Improve Surface Properties
Mild steel (MS) is a soft metal having various applications in the field of engineering. Mild steel is subjected to surface contact with other metals such in lathe guide ways, dipper dozer teeth’s with soil , nozzles to impact jets etc.Surface improvement technique has been chosen for the study to improve the surface characteristics of material. Hardfacing has been done on mild steel after applying chromium paste .Three factorial design has been chosen by taking chromium percentage and current as parameters. Higher percentage of chromium and lower current gives higher hardness and having minimum wear rate.

Performance Study on a Pier Designed using Force based and Direct Displacement Methods
An elevated metro system is more preferred type of metro system due to ease of construction and also it makes urban areas more accessible without any construction difficulty. An elevated metro system has two major elements pier and box girder. This paper concentrates only on the design of pier and its performance. Conventionally the pier of a metro bridge is designed using a force based approach. During a seismic loading, the behaviour of a single pier elevated bridge relies mostly on the ductility and the displacement capacit y. It is important to check the ductility of such single piers. Force based methods do not explicitly check the displacement capacity during the design. The codes are now moving towards a performance-based (displacement-based) design approach, which consider the design as per the target performances at the design stage. In this paper, performance of a pier designed by a Direct Displacement Based Design is compared with that of a force-based designed one. The design of a pier is done by both force based seismic design method and direct displacement based seismic design method and perform ance assessment is done based on both the methods.

Comparison of Two Similar Buildings with and Without Base Isolation
Reinforced concrete is a major construction material for civil infrastructure in current society. Construction design has always preceded the development of structural design methodology. Dramatic collapse of buildings has been observed after each disastrous earthquake, resulting in loss of life. To prevent such a loss Base isolation is used which enables a building to survive potentially devastating seismic impact by providing flexibility into the connection between the building and the foundation. The mechanism of the base isolator increases the natural period of the overall structure, and decreases its acceleration response to earthquake/seismic motion. A reinforced concrete building with lead rubber bearing is used. The study analysis performed to check for the adequacy of the base isolation against earthquake damage when compared to the conventional earthquake resistant design. A building was analyzed using the equivalent lateral force method and response spectrum analysis as fixed base (FB) and as isolated base (IB) with lead rubber bearing. The analysis represents a case study for reinforced concrete to show the ultimate capacity of the selected bearing system, and to make a comparison for the difference between the isolated base and the fixed base buildings. Results show that the presence of the lead rubber bearing reduces significantly the displacement, moment and shear generated for the same mode and hence the reinforcement required is also lesser when compared to the traditional fixed based structure.

Mechanical Properties of Alkali Treated Agave Americana (Rambaans) Fibre Reinforced Epoxy Composite
Composite based on short Agave Americana (Rambaans) fiber (untreated and alkali treated) reinforced epoxy resin using three different fiber length (3 mm, 5 mm, and 10 mm length) are prepared by using open mould technique. The composite thus prepared were subjected to the evaluation of different mechanical properties such as tensile and impact strength. The results obtained suggest that composites reinforced with Agave Americana fiber exhibited better mechanical properties than neat epoxy. All mechanical test showed that alkali treated fiber filled composites withstand more fracture strain than untreated fiber composites. Keywords: Composite; Agave Americana fiber; Alkali treatment; Epoxy Polymer; Tensile and Impact strength.
