Application of operations research in the Indian Aviation Industry

The aforementioned paper is an attempt to understand the aviation industry in India and address it’s most common problems. India is said to have higher growth percentages in the sector compared to any other country in the world along with managing the busiest airports in the world In Mumbai and Delhi, in terms of the number of passengers and Number of flights flying in and out during the year. This niche approach helps us understand what flyers are most dissatisfied within their overall flight experience and provide possible solutions. This is an industry which traditionally tends to operate on very thin margins. Considering the tremendous pressure that’s been building on them in terms of growth in frequency of flights, a number of flyers and high fuel prices, it’s important to sustain what’s under their control, and their clientele qualifies as the most important element.

Case Study

Design and simplification of multipurpose cutter using Scotch Yoke Mechanism

The Scotch yoke (also known as slotted page link mechanism) is a reciprocating motion mechanism, converting the linear motion of a slider into rotational motion, or vice versa. The piston or other reciprocating part is directly coupled to a sliding yoke with a slot that engages a pin on the rotating part. The location of the piston versus time is a sine wave of constant amplitude, and constant frequency given a constant rotational speed. This project aims to fabricate the “mechanical multi-cutter” by using Scotch Yoke mechanism with lower price to improve productivity and to reduce the time. The machine is designed such a way that a smooth trace of each cut stump can be obtained using reciprocating blades. The machine performs eventually even in small and soft fields. The mechanical cutters’ innovation will bring a revolution in the development of the agricultural industry

Influence of industrial waste water in Nagpur area on properties of silica fumed concrete

In today's era of modern construction techniques addition of silica fume in concrete to get high strength and superior performance is normal practice. Although we utilise the waste silica fume in concrete, there are many other waste products, bi-products which needs to be utilized in a scientific manner to prevent the deterioration of the environment. Also, all utilization should be done in ways which are helpful to mankind otherwise they will create more haphazard threats. In this study, the effects of industrial wastewater on silica fumed concrete were experimentally investigated. The main objective of the study was to replace the use of fresh water in casting and curing of concrete structures with industrial wastewater and to analyze the effect on various parameters like Tensile, Compressive and flexural strength, Slump, acid resistivity, corrosion of silica fumed concrete. The silica fume was incorporated in concrete at levels of 5%, 10%, 15%, 20%, 25% & 30% while water-cement ratios were 0.45 to 0.49. All tests were carried out after wet curing of 7,14 & 28 days. Tests results show that though silica fume and industrial wastewater both can be used in high-performance concrete, they should be in proper proportion.

Research Paper

Scaling resistance of silica fumed concrete using industrial waste water

In the modern era of fast construction practices due to the inappropriate use of various suer-plasticisers, admixtures and improper curing methods scaling is one of the rapidly upsurging complications in exposed concrete. This problem can be seen in many structures which had insufficient curing and porous finishing layer. Excessive use of deicing salts, severe exposure of concrete and improper mix design add acute complexities to scaling. Main reason for scaling is porous finishing surface. This problem can be solved by using silica fume as it fills the voids between cement particles. Other reason is cyclic expansion and contraction of entrapped water which not only widens the pores but also leaves behind harmful chemicals in residual form. These chemicals can not reside if concrete already possesses the acidic properties. In this research, we used silica fume as partial replacement of cement and mildly acidic industrial wastewater in concrete. Results show that when silica fume is added by 20% of cement and industrial wastewater is added in same proportion as potable water chloride concentration can be reduced by 35% which can be very useful in preventing the scaling.

Cost analysis of building construction by using autoclaved aerated concrete block (AAC), fly ash brick and clay brick as masonry component

This research work was done to show comparative study residential building while considering dead and live load using AAC block or fly ash and a clay brick for G+5 building was done. The use of AAC blocks offers an innovative solution to the construction industry associated with preserving environmental issues. In this work, also an attempt has been made to calculate bricks and blocks quantity per floor. The G+5 building was designed with the help of Staad pro software and the cost calculation for steel take off, cost of structure etc. was carried out. Autoclave aerated concrete (AAC) block has been found to be economical as a construction material replaced by conventional brick. After designing the structure we are found that if we used AAC block in place of conventional brick we are saving almost around 25.08 % of steel in the overall project.
