Bio-CNG production potential from locally available biomass

Today Mumbai is facing the problem of waste accumulation in different areas and limitation of waste disposal sites. These wastes are dumped in the form of big heaps. The degradation of these waste starts after few days. The process of degradation is aerobic at outer layer and anaerobic at inner layers. Due to these reactions, putrescible gases are come out and causes the health hazard. The Bio-CNG plant gives the best solution for this problem. It uses the vegetable waste as raw material and converts it into a high calorific value fuel. Hence it minimizes the waste accumulation and also solves the problem of energy crisis at the same time. In this study 6kg waste is digested under controlled environment condition n a mesophilic temperature range(30°C-45°C) for 26 days to obtain Biogas. The Biogas so obtained contains CH₄, CO₂, H₂S, and Moisture content. The presence of CO₂, H₂S, and Moisture content in Biogas is considered as impurities as it reduces the calorific value of fuel and hence removed using three scrubber units to obtain the composition of natural gas.These three scrubber units contained Sodalime, Silica gel, and Tri-ethylene glycol to remove CO₂, H₂S and moisture content respectively. The Bio-CNG obtained above contains more than 85% of CH₄ which has high calorific fuel value. These Bio-CNG can be used as automobile fuel, for cooking as well as for power generation. It can also be considered an alternative fuel option against the limited stock of conventional fuels like coal, petroleum etc in future.

Design of fixture for floor grid of Asphalt Paver

A fixture is the most effective tool used to maintain the tolerance and precision in manufacturing industries. This project revolves around the development of fixture to manufacture the chassis of asphalt paver vehicle from L&T construction equipment ltd. The design of the fixture is optimized to provide the company to build the chassis more effective and precise with the knowledge acquired during the literature survey. The fixture is set up on the dowel-pin platform. The project will give an overall development of a fixture from the design process till the scaled prototype going under multiple iterations of analysis through Finite Element Analysis Method. The parameter or the constraints in the design are studied thoroughly such that no failure of the fixture occurs during high volume manufacturing in the company. The end product will be designed considering parameter which could be affected by various shop floor activities. Also carried out tolerance stack-up analysis to find out whether the introduced precision tolerance at the component level is meeting the assembly level functional requirement. The material selected for fabricating the fixture is specified for frequent periodic usage and open environment. The final product will meet all the requirements for large volume manufacturing in L&T construction equipment ltd.

Deadlock recovery and mutual exclusion with atomic operations of cloud storage

While using consumer electronic devices consumers continue to produce and spend a large amount of data. To store consumer’s data, a huge volume of storage is needed. A cloud-of-cloud which is a virtual cloud storage service using heterogeneous public cloud storage services can be a solution. To support concurrent accesses for multiple consumers and devices, a mutual exclusion in a cloud-of-cloud is necessary. From the base paper, they proposed a mutual exclusion method for concurrent access in a cloud-of-clouds. The proposed method includes an atomic operation for cloud-of-cloud a deadlock recovery and a race condition control. To evaluate the proposed method, we modified two modules of saving me which is a cloud-of-clouds storage service system with experiments on the implemented system, we found out to the optimal number of files in a file table and the deadline time for deadlock avoidance. The proposed method does need not only any server system but also any communication between clients. We confirm that the proposed method provides mutual exclusion features to deadlock avoidance.

Characterization of bioactive components from petiole of two varieties of colocasia seen in Kerala

Colocasia is a genus of flowering plant belongs to the family Araceae native to South Eastern Asia and Indian subcontinent. Some species are widely cultivated and naturalized in other tropical and subtropical regions. Different varieties of Colocasia are seen in Kerala of which Colocasia aquatilis is labeled as an aggressive weed that grows in dense clusters along lake shores and riverbanks, displacing native shoreline vegetation. . Qualitative analyses of two samples are done using crude extract from both the varieties. Antimicrobial activity of wild variety is evaluated in both gram positive and gram negative bacteria using pure extract. Even though both comprise the same genus Colocasia, significant differences were seen in the result of these varieties. In our work , we have used two common varieties of Colocasia one is edible variety Colocasia gigantea and other one a a weed Colocasia aquatilis

Formulation of solutions of a special type of standard congruence of prime modulus of higher degree

In this paper, a special type of congruence of the prime modulus of higher degree is considered. A direct formula is established. The formula is well-tested by solving suitable examples. A comparison is made with the method established by Eugen Vedral and the method presented in this paper and the method is proved to be a generalization of Eugen Vedral's method. It is proved more useful than the method suggested by Eugen Vedral.

Managing overbooking in hotels: A probabilistic model using Poisson distribution

Yield Management is commonly practiced in all hotels and other industries where advance booking is required. Various revenue and non-revenue tools of yield management have been practiced and applied. One important tool for yield management is using overbooking in hotels and airlines industries. For management at an operational level, a sound understanding of overbooking will allow maximizing revenue. The real challenge arises when faced with the question regarding how many overbooking is optimum. If we are overly cautious and overbook very less, it would mean a loss of revenue for the hotel. On the other hand, if we overbook to a large extent it could result in confirmed reservations being walked (turned away). This may lead to unsatisfied guests and a poor brand image for the hotel. Hence a balanced approach is required which will help us optimize the overbooking level. In most hotels, this is achieved by adjusting overbooking level based on the experience of Front Office manager. This paper utilizes Poisson distribution as a tool to model the probability of no-shows in a hotel using historical data and hence optimize the number of overbooking to be accepted in a given time period.
