Thermal and Vibrational Analysis of Shell and Tube Heat Exchanger
-Karthikprabhu.T ; B.Annadurai; B.Prabhu
Heat exchangers are devices used to transfer heat between two or more fluid streams at different temperatures. A very serious problem in the mechanical design of heat exchangers is flow induced vibration of the tubes. In this paper a simplified approach to optimize the design of Shell Tube Heat Exchanger [STHE] by flow induced vibration analysis [FVA] is presented. The vibration analysis of STHE helps in achieving optimization in design by prevention of tube failure caused due to flow induced vibration. The main reason for tube failure due to flow induced vibration is increased size of STHE. It is found that in case of increased size of STHE, the surface area and number of tubes increases, thus the understanding and analysis of vibration becomes a very difficult task. Again it is found that flow induced vibration analysis is considered as an integral part of mechanical & thermal design of STHE. The detailed design and analysis work was carried out at Precision equipments (Chennai) Pvt.Ltd. Read More...

An enhanced Method for performing clustering and detecting outliers using mapreduce in datamining
-Mayuri G. Vadgasiya ; Prof. Ishan K. Rajani
Existing studies in data mining focus on Outlier detection on data with single clustering algorithm mostly. There are lots of Clustering methods available in data mining. The values or objects that are similar to each other are organized in group it’s called cluster and the values or objects that do not comply with the model or general behavior of the data these data objects called outliers. Outliers detect by clustering. Many Algorithms have been developed for clustering. Where partitional and Hierarchical Clustering is the two well known methods for clustering. In comparison of Hierarchical and Partitional Clustering Majority of the Hierarchical algorithms are very computationally, complex and consume high memory space. Whereas majority of Partitional clustering algorithm have required a linear time with better effectiveness. The clustering quality is not as Better as that a Hierarchical clustering algorithm. Hierarchical and Partitional Clustering algorithm have advantage over each other so in our proposed algorithm we integrate the Partitional Algorithm K-Modes because of Categorial Dataset and Hierarchical Clustering Algorithm CURE because of Large dataset, robust to outliers and identified cluster having non-spherical shape. And we plan to implement that algorithm in MapReduce Framework so the execution time of the algorithm is improve. Read More...

-S.G.Shiny ; M.Kalimuthu
In most automotive companies they maintain the stock details in Excel sheet, that’s not secure for all transactions. Here the E-excel bills of materials are computerized and an easy viewing and tracking of all bill details are done. The bills here contain both the material needed and the primary design of BIW (Body in white) for reference, if any material is to be added or removed from bill or in case of any change in design the bill is updated (i.e) revised. Since bill contain the primary design and the material used which might be needed by other company to produce a better product or to attract customer to produce the same product with some change in design for low cost. This leads to concern in security so a new technique for securing bill of material is introduced in proposed system to provide higher security from hacker like third party hacker, employee leak data to another company. This primarily concerns when unauthorized remote computer break-ins through communication networks such as the Internet, but also includes those who debug or fix security problems, and the morally ambiguous. A secured environment for billing of material is provided using data leakage detection, IDS, IP synchronization. The system is tested for its effectives, flexibility, accuracy and user friendly.

A Review Paper on Cluster Based Ant Defence Mechanism Technique For Attack In MANET
-Sweety Patel ; Sanket Patel; Rinkal Patel; Dhvani Panchal
A selective forwarding attack is one of the most crucial security problems in MANET. Usually such attacker degrades the network performance in terms of packet loss rate, collision, and overhead. Designing MANET that can work reliably even in the presence of inside packet drop attackers is really challenging. In ant based defense mechanism we have implemented S-ACK scheme to transmit the secure acknowledgement. To detect attackers, a trust model is designed. The Forward ant agents transmit back the digitally signed SACK through the Backward Ant agent to detect any selective forwarding attack against any source node. Cluster distributes traffic among diverse multiple paths to avoid congestion, which optimizes bandwidth using and improves the sharing rate of channel. It uses clustering’s hierarchical structure diverse to decrease routing control overhead and improve the networks scalability. By implementing the algorithm on the OPNET environment, the result shows that this algorithm balances the load of the network and deals with the change effectively of the network topology, and also improves the reliability, throughput and stability of the network efficiently.

-Brijesh V Dave ; Balvant J Makwana; Prashant D Sanchaniya; Bhagwat V Pandya; Ranjit A Solanki
This paper discusses about the Mode Conversion from TE11 to TM11 mode in circular waveguide using step discontinuity is investigated. We use this method for Ku band (12GHz – 18GHz) application and our designed frequency is 15 GHz. We get the amount of power converted from TE11 to TM11 is 10 to 20 %. In this paper we have designed the light weight, compact size and high directivity Circularly Polarized waveguide with high Directivity, high Gain, low return losses and good VSWR. It is found that an abrupt change in guide radius (step) will produce a wide range of mode conversion which can be used in most dual – mode feed horn applications. The step discontinuity is found to produce relatively constant mode conversion over a wide band of frequencies. In this we have varied the length, flare angle, aperture diameter of the conical antenna These dimensions will explain the required features such as impedance matching, radiation pattern of the conical antenna. The electromagnetic accuracy of the antenna is measured with the help of High Frequency structure simulator (HFSS) Software. The measured results of the conical antenna confirmed the simulation results and satisfied the design requirement. In view of this paper, the measured results show that this antenna has gain of 10.80 to 13.20 dB, bandwidth of 300 %, return losses level of -25dB. Simulation for horn antenna has been done on Ansoft HFSSv11. Read More...

A time series data were obtained from NIMASA and NPA annual bulletin (2004-2013) on the pillars of cabotage and total cabotage trade operations were analysed using the ordinary least square (OLS) method of the Multi linear Regression algorithm, and were analysed with the aid of Statistical Package for Social Science (SPSS V.20), to determine the degree of significance of the pillars of cabotage as it influences cabotage trade operations. From the findings, it was deduced that, the number of Nigerian registered vessels (X2) and indigenous human capacity development (X3) variables are statistically significant and correlates positively with the dependent variable. It was however, recommended that marine transport policy makers should stimulate private and public sector investments in the development of maritime infrastructure and construction of ship building dock yards. In conclusion, cabotage trade operations in Nigeria needs strict control and management measures, so that the problems of foreign domination can be effectively checkmated and maximum efficiency achieved.

-Shinde Rahul Kashinath ; Patale Sneha Ashok; Pawar Aniket Gajanan; Shinde Vidhya Sunil
In recent year weight reduction is most important research in Automobile industry. Reduction of weight while increasing or maintaining good strength of products is most important in the modern world. And this weight reduction is possible by introducing Composite materials .Therefore composite materials are solution of such type of problems. By using composite material we design a composite leaf spring for suspension system of light weight vehicle. In this we describe design and analysis of composite leaf spring. The objective of our product is to compare the strength and weight of composite leaf spring with that of steel leaf spring. Now a day’s industries are interested for replacement of steel leaf spring with that of composite leaf spring, because the composite materials has high strength to weight ratio, good corrosion resistance & low weight. There are different composite materials. The material selection depends upon availability of resource and also depends on its properties. In our project high strength with low weight composite material is required because it is used in suspension system. The composite materials E-glass epoxy, carbon epoxy, graphite epoxy, polythelylene terephthalate, polytetrafluoroethylene are actually used. The most preferable composite material is glass fiber reinforced polymer (E-glass epoxy). The strength of composite multi leaf spring varies in percentage is depending on material selection. If we use E-glass epoxy then about 60-70% weight reduction is possible. The design of model will be done on CATIA & analysis on ANSYS. Read More...
