Title: Marine Propulsion Engines and Design of Propeller Shaft

Authors: Anoop Johny,S.Sunil, Besta Manikanta Raju, Shaik Nazma Sharon

For Abstract: Click Here
In this report an attempt was made to study about the various failures of the piping system and repairs. A deep study of ship building from the steel plate treatment to final assembling of various blocks and the in between processes has been made. The study consists of plate treatment, plate cutting, gas cutting processes of the material removal, and vessel preparation as per design, welding processes, block preparation based on crane capacity, final assembly, piping system incorporation and failure in piping of ships. The propulsion of merchant shipping has, during the last century, undergoes a significant transformation. It is now dominated by diesel propulsion machinery with the cost of fuel accounting for a large proportion of the running costs of the ship. Against this background, recent developments have led many in the industry to question whether the present modes of ship propulsion are sustainable due to three main factors: • Rising fuel costs as a result of the escalating price of oil. •Environmental regulations introduced to mitigate the effects of climate change. •The potential introduction of carbon taxes  The report focuses on the recent techniques of alternate fueled engines that are suitable to ship and the useful data is presented in all possible aspects. Design of shaft systems, which is used to transmit power from one machine part to another. The design calculations has been done according to designing from first principles and design from classification society rules. The valves obtained from classification society rules are compared with valves obtained from first principles and these are in the safe limits. The shaft calculations are mainly based on combined bending and torsion and design of bearings.

Title: Design of Turbo Charger for Two Wheelers

Authors: N.S.Vishnu Vardhan,P.Deepak Raj

For Abstract: Click Here
The accentuation today is to give a doable building answer for assembling financial matters and "greener" street vehicles. It is a result of these reasons that turbochargers are presently ending up plainly more prominent in car applications. The new turbocharger is coupled to an airwater bury cooling framework to diminish the delta air temperatures. This venture dissected the bury cooling framework and tried the last plan in the vehicle. The outcomes demonstrate that the cooling framework parts bought are satisfactory for this framework. The aim of this paper is to provide are view on the techniques used in turbo charging used in two stroke single cylinder petrol engine by this to increase the engine output and reduce the exhaust emission levels. This paper is to analyze a turbocharger system in a two stroke petrol engine. The perfect turbocharger configuration would be littler than the framework bought. The paper will likewise make speed sheets for use in figuring the important parameters for another turbocharger framework, or to alter the present framework.

Title: A Study for the Extraction of Dynamic Characteristics in CNC Machine Tools from Trajectory Measurement

Authors: Ben-Fong Yu, Jenq-Shyong Chen

For Abstract: Click Here
In the present production environments, machining centers are increasing required to be fast, accurate, and stable at the same time during processing. The dynamic characteristic of  CNC machine tool is an important factor that has influence in high-speed movements. First we were analyzing the kinematic profiles (position, velocity, acceleration, and jerk) for tool-path planning that have significant effects on the dynamic behavior of machine. In order to define the machine’s dynamic characteristics along feed motion, this paper builds method on the measurement for motion trajectory by using the motor encoder, linear scale, and cross grid encoder (KGM). The KGM is mounted on the tool center point (TCP) in machine tools. The position of TCP was related to the tool and table in the machine tool, it's useful to guarantee obtain the machine's dynamic response completely. Finally we have modified the relevant variables for kinematic profiles, and we have proposed to stimulate the mechanical resonance for machine by the simple tool-path. In experimental results of the TCP measurement, it’s shown that the machine resonance can be decreased effectively.

Title: Comparitive Analysis of Corrosion Controlling Techniques on Hull of the Ship

For Abstract: Click Here
In the ship building procedure and its operational period, the ship is presented to different substance impacts of the condition that reason distinctive consumption harms. Serious basic material harm caused by erosion can influence both the security and general existence of the ship. To log jam or  take out the erosion procedure on the boats they must be secured by different measures an innovative strategies. The paper shows the mechanical procedures of erosion insurance, beginning from auxiliary and innovative measures, use of defensive coatings, the utilization of consumption safe materials, cathodic security and the work of inhibitors. Thusly, the consumption  insurance in shipbuilding is an essential innovative process, which may eventually and fundamentally influence ship's administration period, as well as the cost of the ship building and support costs. For inorganic and natural coatings the qualities ought to  be given volume by volume. The use of zinc-rich introductions on ferrous substrates is an extremely  effective strategy for anticorrosion assurance. To accomplish a long life covering framework you  require a zinc groundwork as a first coat. Zinc offer triple security since it; seals the hidden metal from contact with its destructive condition, gives galvanic assurance and "repairs" minor harms in a covering framing a hindrance to encourage electrochemical activity. A short portrayal of these properties will be introduced in this paper. Contrasted with epoxy the silicates can be  pigmented at amazingly abnormal amounts of zinc  tidy offeringzinc to zinc metal contact and subsequently, great cathodic assurance properties like those acquired with electrifying. There is a pattern in new worldwide benchmarks that the interest for zinc content is the same for zinc epoxy and zinc silicate given weight by weight. In the event that it is a desire to have a similar zinc content level.

Title: Laboratory simulation study of Bituminized Jute Paving Fabric for its potential application in road constructions

Authors: Rajib Bhattacharyya, Swapan Kumar Ghosh

For Abstract: Click Here
Geotextiles have witnessed unparalleled growth worldwide in recent years in the field of different civil engineering constructions. With the growing environmental concern the global emphasis is towards the application of eco-concordant, renewable green products and this has inclined towards the natural fibre-made fabrics. Jute Geotextile (JGT) is increasingly gaining ground over its synthetic non-biodegradable and toxic counterpart in different significant civil engineering constructions. One such prime application of JGT is in road construction where it has been restricted so far as underlay. Hence, there is an urgent need to design and develop a fabric as overlay on existing pavements to stay technically and economically competitive in the global market. Such a fabric will not only prove techno-economically viable but will also reduce the carbon foot-print generation to a large extent. This paper focusses on the laboratory simulation study of Bituminized Jute Paving Fabric (BJPF) carried out by the Department of Jute and Fibre Technology, University of Calcutta in collaboration with Central Road Research Institute (CRRI), New Delhi to establish its efficacy in reducing the cost of maintenance of the road and serving as a partial substitute of bitumen mastic enhancing thereby the life expectancy of the road.

Title: Mineral Composition of Some Accessions of Sesame Seeds (Sesamum Indicum L.) Collected from Morocco

Authors: H.Rizki, A. Nabloussi, F.Kzaiber, H.Latrache , H.Hanine

For Abstract: Click Here
The mean heavy metal and minerals of sesame seeds were determined by ICP-AES. The mean values of Ca, Mg, K, P varied with an average of 971.142, 347.4, 493.571 and 545.828 mg/100g respectively. In addition, Fe, Zn and Se values of sesame seeds were found at the levels between 14.8 to 15.9, 5.74 to 5.96 mg/100g and 51.9 to 60 µg/100 g respectively. The results showed a high content of Calcium, Phosphorus and Potassium in the accessions, in addition to a significant amount of Selenium. Thus, a variation in the amount of these elements was noted for the studied areas, which may be due to several factors related to soil types, irrigation and harvest period.
