Authors: Kaur Sharndeep, Gupta Anuj

IJAET/ Volume V/ Issue IV/ Oct.-Dec..'2014/01-05

ABSTRACT
MANETs is a collection of wireless mobile nodes forming flexible networks, thus they do not require any existing infrastructure and centralized access points. With increase in the use of Mobile Ad hoc Networks security became an fundamental requirement due to its dynamic topology, limited processing capability, bandwidth constraints, lack of central control and high bit error rate. To provide protected communication between mobile nodes, there is need to build multifence security and routing solution to overcome from these challenges. In this paper we attempts to give a review on various secure routing protocols, security analysis of available secure protocols by identifying their advantages and disadvantages as well as comparing their relative metrics and requirements. This paper structured into three sections: Section first includes a brief introduction of MANETs with their routing protocols. Section second explains the security attacks and challenges in MANETs. Third, discusses the security analysis of each secure routing protocols with comparison.

TACKLING MUDA – THE INHERENT WASTES IN MANUFACTURING PROCESSES

Authors: Dr. Charles Chikwendu Okpala

IJAET/ Volume V/ Issue IV/ Oct.-Dec..'2014/06-11

ABSTRACT
The inability of many manufacturing companies to remain viable and also compete effectively in today’s world class manufacturing has been blamed extensively on their difficulty to identify, reduce, and possibly eliminate all wastes that are inherent in their manufacturing processes. This paper introduced the concept of waste (otherwise known as muda in Japan) in Lean Production System, and also gave a detailed explanation of the entire 7+1 wastes that bedevil manufacturing processes. The various approaches, tools and techniques of tackling muda were discussed in detail, although it was noted that companies will not achieve the desired results if the tools are not properly utilized; the paper went a step further to discuss their specific applications and benefits which will assist in starting improvement processes, increase the overall awareness of quality, and also enhance the change of attitude of employees. Finally the paper concluded that the effective tackling of all wastes in manufacturing processes will not only enable companies to remain competitive, but will also lead to increased throughput, as Waste identification and subsequent elimination is one of the most effective ways of increasing the profitability and viability of any business.

THE BENEFITS AND APPLICATIONS OF NANOCOMPOSITES

Authors: Dr. Charles Chikwendu Okpala

IJAET/ Volume V/ Issue IV/ Oct.-Dec..'2014/12-18

ABSTRACT
The intensification in research of nanostructure materials in recent years has occurred primarily due to their attractive potential, that is mechanical and physical properties significantly improved compared to the conventional grain materials. At the most basic level of common understanding, nanoscience involves the study of materials where some critical property is attributable to an internal structure with at least one dimension less than 100 nanometers. This paper gave a broad definition of nanocomposites, nanofilers, the benefits of nanocomposites, the processing, milestones in nano development, the strengths and limitations, as well as the various applications of nanocomposites. Due to the higher surface area available with nanofillers, polymer nanocomposites offer the potential for enhanced mechanical properties, barrier properties, thermal properties and flame retardant properties when compared to conventionally filled materials. The knowledge of the immense value of nanocomposites will enable the manufacturers to recognise that polymer nanocomposites will herald a new era in materials advancement just as polymer composites transformed the face of industry many years ago. On the applications of nanocomposites, the paper explained that experimental work has generally shown that virtually all types and classes of nanocomposite materials lead to new and improved properties, when compared to their macrocomposite counterparts. Therefore, nanocomposites promise new applications in many fields such as mechanically-reinforced lightweight components, non-linear optics, battery cathodes and ionics, nanowires, sensors and numerous other systems.

Authors: G.R. Chavhan*, S.W.Burande, Dr.L.P.Dhole

IJAET/ Volume V/ Issue IV/ Oct.-Dec..'2014/19-21

ABSTRACT
Shock absorbers are an important part of the suspension systems of automobiles, motorcycles, and other wheeled or tracked vehicles, as well as aircraft landing gear and the supports for many industrial machines. Large shock absorbers have also been used in structural engineering to reduce the susceptibility of structures to earthquake damage and resonance. A transverse mounted shock absorber, called a yaw damper, helps keep railcars from swaying excessively from side to side, and is important in passenger railroads, commuter rail, and rapid transit systems because it increases passenger comfort and prevents railcars from damaging station platforms.
The main function of vehicles suspension system is to separate the vehicle body and passengers from the oscillation created by the irregularities and to provide continuous contact of vehicle’s wheel from the road surface. The vehicles suspension systems are mainly classified in three categories (1.passive suspension system 2.semi-active suspension system 3.active suspension system).
Firstly we have shock absorber of PLEASURE automobile as an existing model. We will check the strength ability, damping factor, shock absorbing capacity etc with the help of software available at the college by static and dynamic analysis. For this we have to take the dimension of each part of existing shock absorber. For this purpose we are to cut shock absorber on the lathe machine and then make the model on the Pro-E/CAD showing dimension of each component. After this we have to use the ANSYS software for static and dynamic (harmonic) analysis by changing three different materials for spring. So that we will be able to suggest which is better and also to tell which type of material will help to increase the ability of shock absorber.

THE TOOLS AND TECHNIQUES OF LEAN PRODUCTION SYSTEM OF MANUFACTURING

Authors: Chukwutoo C. Ihueze and Charles C. Okpala

IJAET/ Volume V/ Issue IV/ Oct.-Dec..'2014/22-27

ABSTRACT
This paper discussed in details the main tools and techniques of Lean Production System (LPS) – a manufacturing strategy that has been adjudged the world’s best practice, and is aimed at improving throughput and profitability, by eliminating all wastes that are inherent in all manufacturing processes. In LPS, waste (muda) is seen as anything that destroys resources and does not add value to the requirements of the customer. The production approach is geared towards turning manufacturing which used to be full of waste of time and resources into a well organized, efficient and more profitable venture. The discussed tools and techniques are Cellular Manufacturing, Just-in-Time, Total Productive Maintenance, Value Stream Mapping, Poka Yoke, Five-S Practice, Single Minute Exchange of Dies, Takt Time Analysis, Kaizen, Visual Management, and Single piece flow. The paper revealed that the successful application of the various tools and techniques of LPS assists manufacturing companies in starting improvement processes, increase the overall awareness of quality, and also enhance the change of attitude of employees. However, the paper also explained that the tools and techniques will not achieve the desired results if they are not properly utilized; this is because LPS is not just the application of a bunch of tools but rather a completely different approach of manufacturing.

Authors: K. Sivanagireddy, Ch. Adibabu

IJAET/ Volume V/ Issue IV/ Oct.-Dec..'2014/40-44

ABSTRACT
In this paper we present wavelet transforms are used to compress the input images by Set Partitioning in Hierarchical Trees (SPIHT) algorithm and by incorporating lifting concepts. SPIHT algorithm on wavelet transform which gives better simplicity and better compression compared to the other techniques. But to scale the image more so as to get better compression we are using the Lifting-based Wavelet transform (LWT) because it requires lower memory without affecting the result of Wavelet transform. This technique is implemented on 2-D images including both colour and monochrome images and validates such compression algorithm by calculating PSNR, and Compression Ratio.

Authors: Paramjit Singh, Kiran Ahuja

IJAET/ Volume V/ Issue IV/ Oct.-Dec..'2014/48-52

ABSTRACT
As with demand of real time scenario there is need of different traffic pattern to be implemented on MANET. Topology management is art of removing redundant links on the network to improve the performance of the network. In this paper we implemented two scenarios. In the first scenario we implemented topology management of clustering scheme with cooperative communication. Also in the second scenario we implemented dynamic traffic pattern like Email, FTP & HTTP on the proposed network. Simulation results show the QoS performances (Throughput, Delay, SNR & Response Time) of different traffic patterns are better on the proposed network..
