Abstract :

The present paper proposes analytical expressions allowing the prediction of damage in different scenarios of collisions involving ship structures. The internal mechanics of the collision is described by a theory of plastic deformation based on the penetration of projectiles on metallic plates. A theoretical model is presented for the analysis of stranding and bulbous bow collision or objects with similar profile, such as underwater gliders or rocks, with structures of the ship hull. The model takes into account the collision energy to calculate the final displacement on the hull, considering the profile of the striking object, the hardening effect and the equivalent thickness method to account for stiffeners contribution. Experimental data found in literature were used to validate the model and limitations are discussed. The comparison of the calculations and literature data revealed that the model predictions were in good agreement in several collision scenarios.

Abstract :

Traumatic injuries and fractures resulting from falls by elderly individuals have become a major issue for the government bodies responsible for health, medical care, and social welfare because they markedly reduce the individuals’ ability to engage in activities of daily living. Major causes of such falls by elderly individuals are decreased balance ability and impairment associated with aging. Proprioceptive information obtained by movement of the lower extremity muscles and joints are important for maintaining balance. However, there have been very few studies concerned with further quantifying lower extremity proprioceptive sense, which for elderly individuals is important for maintaining standing balance. The objectives of this study were to develop the first device to quantitatively evaluate changes in the proprioceptive threshold (motion sense and joint position sense) that is associated with changes in the angle of the ankle during standing and, based on this evaluation, establish methods of evaluating and training joint sense that are needed to improve balance ability by using a new device.

The subjects were five elderly individuals (mean 71.4 years) and seven young individuals (mean 20.6 years) who were not proficient at sports. A new device was used to evaluate the motion sense and the joint position sense during plantar flexion, dorsiflexion, inversion, and eversion of the ankle with the individual in the standing position. The device was shown to be capable of measuring ankle proprioceptive sense during standing to 1 degree of accuracy. The subject stood with their dominant foot on the motor-driven foot plate of the device. Next, the motor-driven plate was inclined at a specified angular velocity, and the subject was instructed to stop the plate by pressing a button near their hand when they felt that the inclination angle matched that of the non-dominant leg. Four movement directions were used for the ankle: dorsiflexion, plantar flexion, eversion, and inversion. The two dorsiflexion angles used were 5 and 10 degrees; the three plantar flexion angles were 5, 10, and 15 degrees; the two eversion angles were 5 and 10 degrees; and the three inversion angles were 5, 10, and 15 degrees. The two angular velocities used were 1 and 2 degrees/sec. For the analysis, the inclination angle of the non-dominant foot was used as the set angle, and the angle at which the subject stopped the plate was used as the stop angle. The error (| set angle - stop angle |) was the test parameter. The minimum error value obtained in the two trials was recorded.

Abstract :

The detection of the mixed microbial communities in an environmental sample has represented a hurdle for long time due to the selection imposed by the culturing on specific media and by the minimum number of cells required. Here, we simulated a contamination of a sterile radiochemical by adding a known amount of Staphylococcus epidermidis and we developed a methodology, based on a metagenomic approach, to isolate DNA without a previous selection, from a low starting material and in limited time. The obtained sequences have been further used to characterize the microbial populations present in the sample using a bioinformatics tool.

Abstract :

MANET has received the significant attention in every field of Information and Communication Technology industry. The nodes in Mobile Ad hoc networks continuously move leading to randomly changing topology which further leads to many problems such as link breakages and loss of packets sent by the source node to the destination. In MANETs, the nodes are mobile and battery operated. As the nodes have limited battery resources and multi hop routes are used over a changing network environment due to node mobility, it requires energy efficient routing protocols to limit the power consumption, prolong the battery life and to improve the robustness of the system. This paper evaluates the performance of various adhoc routing protocols such as DSDV, AODV, DSR, TORA and AOMDV in terms of energy efficiency and it also proposes a new routing algorithm that modifies AOMDV and it provides better performance compared to all the above protocols.  This paper gives an overview of the MANET and AOMDV protocol .It also explains its advantages and disadvantages.

Abstract :

In automotive industry several kinds of alloys are used for manufacturing the components. With the increasing use of aluminum wheels in automotive industry, the aluminum foundry industry had to focus on the quality and reliability of the components. The quality of the components can be increased by monitoring the defects and evaluating it.

Aim of this study is to drop the casting defects with the help of quality control tool. This study shows the systematic approach to find the root cause of major defects in aluminum castings using defect diagnostic approach as well as cause and effect diagram. Casting defect analysis is carried out using techniques like historical data analysis, cause-effect diagrams, design of experiments and root cause analysis. Data from X-ray inspection (Radiographic Inspection) have been collected along with the production parameter data. Using Pareto chart major defects in the aluminum castings were noted. The major defects for the rejections during production were identified as shrinkages, inclusions, porosity/gas holes and cracks. Each defect is studied thoroughly and the possible causes for the defects are shown in Fishbone Diagrams (Cause Effect Diagrams). As the shrinkages mainly occur due to lack of feed ability during the fluid flow the stalk changing frequency is noted along with the shrinkages defects and a relation is drawn between them. As hydrogen forms gas holes and porosity in the aluminum castings the amount of hydrogen present in the molten metal is studied by finding specific gravity of the samples collected. The molten metal temperature affects the amount of the hydrogen absorbed by it. .So the effect of molten metal temperature on the specific gravity of the sample collected have been shown in a graph and the optimum value for molten metal temperature was found out.

Abstract :

Almost industrial activities play an important role in human life by delivering the adequate resources. However oil and gas pipelines represent the back bone for these industrial resources due to oil and gas transportations around the world. But unfortunately sometimes great losses are recordedannually due to leakages in thesepipelines. So this idea attracts most of the researcher to shrink the heavy losses by incorporating the artificial intelligence theory to predict the behavior for these pipelines and estimate the probability for leakage occurrence and provide enough information about leak position and size rather than a prior protective actions against the corrosion and environmental risks if exist. This work adopts a new proposed neural network model with back propagation algorithm as one of the popular methods for leak detection in a pipeline which is usually used to classify the leak size and position along the pipeline. Achieved results of the work in this paper explained the difference between various transfer functions used for hidden and output neurons in ANN, also the confusion matrix for each learning algorithms shows the outperformance for the batching method against the incremental method for weights updating in the BPNN.Also different neuron based transfer functions with various characteristics are compared from classification accuracy and training performance points of view.

Abstract :

This study aims to explore and develop a clearer understanding of the factors that influence success  in Malaysian small and medium enterprises by implementing entrepreneurship and strategic management, as perceived by local owner and/or managers. Using a qualitative approach, fifteen in-depth face-to-face semi-structured interviews were conducted with selected owner-managers of SMEs, forming a judgmental selection, to explore their experiences, beliefs, and attitudes with respect to the external factors of success. The study suggested that there are three generalized factors that influence success and performance in SMEs based on the entrepreneur’s perceptions: the “owner and manager attributes” which involves the language skills factor, financial and networking partnership, and business characteristics with a focus on the location factor, which was mainly associated with the selected districts in Malaysia. The importance of financial resources stemmed from the substantial challenges faced by SMEs in Malaysia. A response to these challenges often adopted an equity model of financial resources. Furthermore, the concepts of conduct, equipment, and commitments, clearly explained the importance of a good infrastructure to the appreciation of success in this type of business. The study contributes to the understanding of the impact of critical external factors on the success of SMEs in Malaysia. The three significant factors could be considered to be ways of understanding the external environment by small business owners and managers, allowing the impact of external factors to become part of the way that the small business owners conduct their business.

Abstract :

Banking bot is an artificial intelligent development for banking operations, which can understand people queries and responds accordingly. The main aim of this project is to develop a banking bot using artificial intelligent algorithms which should be able to analyze and understand user’s queries and react accordingly. For any banking related queries we have to go to the bank or call to customer care. It takes lot of time and effort and bank people are also very busy to attend our queries. On the other hand we don’t get complete information from the customer care executives.  It will be more suitable if we can directly post our queries online or chat with the bank people and get the response within less time. To overcome this problem we proposed banking bot where people can directly chat with a bot and they can integrate all of their bank accounts into same bot account and access them easily. In this Banking bot, we have included the four basic bank operations namely adding and viewing the beneficiary, fund transfer, viewing the balance and mini statement. In addition, users can post any query regarding the banking operations.

Abstract :

The present contribution addresses the construction of political wills in the elaboration of governmental projects. "Lack of political will" is often deplored when certain projects, even though they have their established value, can not be imposed on the government agenda or, when they do, are not effectively implemented. The literature has dealt with the issue from various angles and frames of reference (public policy cycles, stakeholder analysis, advocacy, among others). In order to test the explanatory power of the groups approach or the coalitions of interest (here treated as a synonym), in infrastructure policy, the present article explores the history and content of the concept and establishes a research roadmap to be applied in studies of the decision process in selected infrastructure projects.

Abstract :

The simple counter-flow vortex tube consists of a long hollow cylinder with tangential nozzle at one end for injecting compressed air. Compressed air supplied to the vortex tube is separated into low pressure hot and cold air from its two ends. The exact mechanism of this temperature separation is not known today. Most of the investigators have studied the various operating characteristics of vortex tube based on the cold mass fraction. Vortex tubes of different geometrical configurations give optimum performance at different cold mass fractions.

This paper presents results of Maximum coefficient of performance at given L/D ratio of 32.5 by varying cold mass fraction from 0.1 to 0.9 for 1,2,3,4 number of nozzles carried out on Ranque–Hilsch vortex tube (RHVT). Different parameters such as cold mass fraction, conical valve angle 30º, 45º, 60º, 90º, number of nozzles are investigated. It shows that coefficient of performance increases with increase in cold mass fraction. Also it is observed that valve angle has significant effect on performance of vortex tube. At the end of study it is found that the maximum coefficient of performance is 0.165 at valve angle 300 for nozzle 4.
