In this paper the effect of process parameters of friction stir welded joint for similar aluminium alloys H30 was studied. Taper cylindrical with three flutes all made of High speed steel was used for the friction stir welding (FSW) aluminium alloy H30 and the tensile test of the welded joint were tested by universal testing method. The optimization done using detailed mathematical model is simulated by Minitab17. In this investigation, an effective approach based on Taguchi method, has been developed to determine the optimum conditions leading to higher tensile strength. Experiments were conducted on varying rotational speed, transverse speed, and axial force using L9 orthogonal array of Taguchi method. The present study aims at optimizing process parameters to achieve high tensile strength.

This paper tends to develop for protection for costly appliances which require three-phase AC supply for operation. Failure of any of the phases or sudden change in voltage makes the appliance prone to erratic functioning and may even lead to failure. Hence it is of paramount importance to monitor the availability of the three-phase supply and proper voltage supply and switch off the appliance in the event of failure of one or two phases or if required voltage level is not available. The power to the appliance should resume with the availability of all phases of the supply with proper voltage level. The main advantage of this protector circuit is that it protects three-phase appliances from failure of any phase as well as from fluctuation of voltage. The concept in future can be extended to developing a mechanism to send message to the authority via SMS by interfacing GSM modem. Details description of all types of faults is given below.

This research study investigates preventive maintenance management of diesel engine generators at the Nigerian Maritime Academy, Oron. An optimization methodology taking cognisance of equipment age was applied on failure data of diesel engine generators obtained from the institution’s maintenance data base to provide cost effective maintenance management / replacement programme for critical components of diesel engine generators. The analyzed results using Matlab provides a cost and reliability template which can be used to perform diesel generator maintenance management programme in the academy.

Establishment of vehicular ad-hoc network plays important role in smart traffic management system. Researcher can create VANET by information sharing of road side unit, vehicle and traffic system & implementing it in real world. This system implemented to detect road signs from a moving vehicle. In this technology vehicle is able to detect traffic signs which are on the road side boards e.g. "speed limit" or "school" or "turn ahead". Consider a condition, user is driving a car at night or in rainy season then it is not possible for driver to keep watch on each and every road symbol or the message plates like turn, speed breaker, school, diversion etc. Here in this proposed system every road side board or symbol will use one signal transmitter and the moment vehicle passes from that road side board the vehicle will receive signals with the help of receiver and indicates the symbol on LCD display which is in the car. So that the driver can able to concentrate on driving vehicle.

At present, domestic and overseas researches on concrete cracks mainly focus on the formation of cracks from external factors, such as cracks caused by temperature, external loads and uneven settlement of foundation. Based on other scholars’ study on the reason and settlement of cracks, this paper starts from the defect of concrete structure, and proposes three factors affecting concrete cracks: internal and external stratification during the process of concrete placement, the presence of the transition zone of concrete and multiphase porous system of the cement. In addition, the author has summarized the prevention and repairing measures of cracks.

Development in the field of image processing for reducing speckle noise from digital images/satellite images is a challenging task for image processing applications. Previously many algorithms were proposed to de-speckle the noise in digital images. Here in this article we are presenting experimental results on de-speckling of Synthetic Aperture RADAR (SAR) images. SAR images have wide applications in remote sensing and mapping the surfaces of all planets. SAR can also be implemented as "inverse SAR" by observing a moving target over a substantial time with a stationary antenna. Hence denoising of SAR images is an essential task for viewing the information. Here we introduce a transformation technique called ―Ridgelet‖, which is an extension level of wavelet. Ridgelet analysis can be done in the similar way how wavelet analysis was done in the Radon domain as it translates singularities along lines into point singularities under different frequencies. Simulation results were show cased for proving that proposed work is more reliable than compared to other de-speckling processes, and the quality of de-speckled image is measured in terms of Peak Signal to Noise Ratio and Mean Square Error.
