Abstract: For the last two decades Pune has registered a steep growth in number of public-private vehicles. But the road infrastructure and the utilities have not expanded in commensurate with increase in number of vehicles. The City manifests all the problems of a metropolis like increase in traffic congestion, speed reduction, environmental pollution and degradation quality of life. The problem of urban congestion has been brought out by an unprecedented growth in motorized vehicles which is further aggravated by the interstate truck movement that cuts through the Pune City. Existing public bus service falls short while catering to rising demand. This paper briefly explains to study the concept of BRT and to implement the BRT which factors are required to study the impact on city structure. In this paper, we study the existing city structure and transportation system of Pune city.  

Abstract: This thesis involves in Airfoil aerodynamic performance in heavy rain conditions for particular airfoils with different Cambers. Rainfall is an environmental phenomenon that can potentially influence flight performance. Comparing the simulation results with each other thus predicting significant aerodynamic penalties for the airfoil in heavy rain conditions is going to be carried. Adhered water increases the effective mass of the wings and body and alters the wing's moment of inertia, whereas drop impact imparts downward momentum to the body. Raindrops impacting wings can also produce roughness will increase aerodynamic drag. Moreover, non-uniform distribution of drops across the body and wings may adversely influence control and maneuverability. The percentage decrease in CL and the percentage increase in CD will be going to be calculated. Airfoil Performance degradation in heavy rain at low angles of attack will be determined near the leading edge using ICEM CFD and FLUENT. Finally the major characteristics involved in the airfoil aerodynamic penalties will be indicated.

Abstract: Supply Chain Management is recognized as a leading process improvement, cost saving and revenue enhancing business strategy. It applies to all businesses involved in the delivery of construction projects. Supply Chain Management requires a corporate initiative, supported by strategic and tactical planning, to instill systems thinking and promote a new discipline that companies must master. Construction Projects Supply Chain Management requires a good understanding of production management; planning, design, and construction; and business drivers like other disciplines within an organization, such as structural, mechanical, electrical, or process engineering, accounting and materials management. Supply Chain Management must have a champion who can drive the ideas across disciplines within the organization as well as across organizational boundaries.

Abstract: In this paper, we discuss the method of risk measurement of project risk, based on the risk matrix method. Generally project risk management primarily deals with cost and time uncertainties and risk associated with each activity of the project network. In this paper, we have identified the major risk sources and quantified the risk in terms of likelihood, impact and severity in a complex infrastructure project. The methodology for this work was the response from the experts associated and involved in this and other projects. The risk assessment for this project is carried out by risk matrix method. And risks are categorized according to the priority.

Abstract: A large quantity of rice husk in Nigerian rice milling industries poses a serious environmental and health hazards. Rice husk particleboard is therefore one of such material which may be considered a potential substitutes for wood and woods-based board products.
This study presents an experimental work which investigates the potentiality of rice husk in the production of particleboards using starch and wood glue (Top bond) as an alternative source of adhesives. The weighing scale was used to weigh the rice husk, starch, and wood glue (Top bond) and the mixture ratio adopted being 0.75kg: 0.15kg: 0.10kg of the rice husk, starch, and wood glue respectively, thoroughly mixed manually by using the mixer. The mixture was then poured into a mould with a dimension 300mm x 300mm x 15mm. The particleboard was compacted using a hydraulic press in two (2) compacts. The particleboard was tested for water absorption in both cold and hot media. The cold absorption test was performed by immersing the composite sample was immersed into the cold water a period of 30mins, 1hr, 2hrs, 4hrs, 6hrs and 8hrs at room temperature (25oC) and the thickness of the board. In hot absorption test, the composite sample was immersed into the hot water with temperature ranging 45oC, 65oC, 85oC and 100oC at constant time of period of 1hour and the thickness of the board taken.
The percentages of absorption were then calculated for both the cold and the hot medium. The thickness of the particle board produced increases with an increasing time and temperature for both the cold and hot media water, until a point is reached when a saturation point is attained and the board could no longer accommodate any more water. At this point the density remains constant. This value indicates that the board should be reserved for indoor application since percentage water absorption absorbed increases with increasing time of immersion.
It is concluded that rice husk waste can be utilized in the manufacture of a water-resistant particleboard tropical area like Nigeria with long raining season. The use of starch, a biodegradable adhesive reduced the use of the more expensive synthetic adhesive based on petroleum resources. The test results showed that the rice husk, starch and wood glue combination provides results which have high potential to be used in the production of particleboard.

Abstract: A Jet erosion is normally used to study the relative erosion behaviour of different material at moderate solid concentration, velocity, and particle size and impact angle. A slurry pot t is then fabricated by inserting propeller from the bottom of the cylinder and is rotated at the speed required for uniform distribution. The test specimens are then mounted on test fixture which is fixed and has a provision to move in different angular position to find out the wear for different angles. Erosion of materials is occurs due to the impact of high velocity of slurry which is comes out from the nozzle and impacting on the test specimen. Two different experiments are conducted preliminarily first for repeatability test for fix parameters such as 450,particle size 655micron,angle and 10% solid concentration for 60 minutes and another one for authentication. The results were obtained for ductile material and are found in good arrangement with the literature.

Abstract: Radio frequency identification is the hot topic of wireless security research, because RFID message exchanges through open air are attracting the attention of malicious users. The Quadratic Residue assumption supported by the Chinese Remainder Theorem (QR-CR duo) is one of the many diverse functions used for encrypting the exchanged messages. However, authentication protocols using the QR-CR duo have been facing severe analysis. The present work analyzes one of the very latest works using the QR-CR duo in a scheme, similar to protocols previously shown to have vulnerabilities. The analysis demonstrates the presence of serious vulnerabilities in the design. The consequences of the deficiencies in the scheme are important in reaching a final decision whether to recommend the proposed scheme; because the protection of the users of an authentication protocol is of great concern.

Abstract: The error in scientific computing has induced serious accidents and disasters. New proposal are presented toward an error reduction mechanism or management in scientific numerical computing. The first important point is to share the knowledge of error with other researchers. Sharing known error contributes to the error reduction or management. In addition, for specific problems, one can prepare multiple programs with different rounding methods and or different precisions, and can compare the results among the programs generated for a specific problem. If differences appear among the results, it suggests the specific problem may have some error problem. The second method provides a simple and effective inference method of the error. Error come from various sources, from physics and mathematical model error, insufficient numerical precision, floating point precision, programming error, data processing error, visualization errors, as well as human errors. Another type of error comes from the discretization step size of ∆t  or  ∆x in numerical computation, the discretization step size of ∆x  or ∆t  must be selected appropriately in numerical computations in order to describe short waves phenomena concerned to the target programs. This error would be also reduced by multiple program computations with the different size of  ∆t and ∆x, to find out the appropriate step size under keeping numerical stabilities. In this paper we proposed these error reduction mechanisms.
