ABSTRACT Natural gas hydrate formation prevention by injection of chemical inhibitors of different weight percentages was investigated. The chemical inhibitors investigated in this study are methanol, ethylene glycol, diethylene glycol and triethylene glycol of different weight percentages of 10%, 20%, 25% and 40%. Natural gas hydrate formation was mitigated against by these chemical inhibitors by […]

ABSTRACT Design and implementation of a low cost control scheme of sensor less Permanent Magnet Synchronous Motor (PMSM) for efficiency improvement of pump and compressor is presented in this paper. The main problems of sensor less control of PMSM are starting jerk and loss of synchronism during acceleration. Due to absence of rotor position sensor, […]

ABSTRACT Strategies were devised for development of inorganic binders with moderate levels of moisture resistance using primarily natural raw materials subjected to simple processing methods. The raw materials considered here included gypsum, lime, citric acid and soda ash. In this binder, gypsum and calcite (resulting from carbonation of lime) provide binding effects, and the presence […]

ABSTRACT In this Work, a comprehensive practical study in total cost estimation of welded Aluminum 6061 pipes using three different types of welds, Metal Inert Gas (MIG), Tungsten Inert Gas (TIG) and Friction Stir Welding (FSW) . The cost component of joining Al 6061 aluminum pipe welding was each component cost (labor cost, Power cost, […]

ABSTRACT The effect of semi nano filler from rice husk on the mechanical properties of epoxidized natural rubber was studied and compared with carbon black filled epoxidized natural rubber composite. The particle size distribution of the milled rice husk was determined using optical microscopy and digital imaging technique. The semi nano powder obtained by ball […]

ABSTRACT The rapid growth of renewable energy globally is connected to the developed performance of the system especially in solar and wind powers. This is in association with enormous research conducted worldwide. After Saudi Arabia has acknowledged the new vision of the country in 2030 which of the major aims is to enhance the utilisation […]

ABSTRACT Lignocellulosic fibrous materials account for second largest biopolymers after cellulosic material. The presence of lignocellulose in fibres gives distinct characteristics such as improved strength, stiffness and reinforcement of the material. It also gives distinct identity as a textile fibres i.e., bast fibre. However, there are more than 1000 derivatives of lignocellulosic materials of which […]

ABSTRACT The main production constrain is the availability of reliable and safe planting material. Planting materials obtained through conventional methods do not meet the increasing demand for planting and they are of poor quality. Tissue culture approach can solve these problems but it is yet to benefit majority of small scale farmers because of the […]

ABSTRACT Image segmentation is the important task for image analysis and understanding it. The segmentation of color image is challenging task in the image analysis process. Segmentation of color images gives more information than gray scale image. This paper performs segmentation of color image in different color spaces, as segmentation of RGB color image not […]

ABSTRACT Real time systems are type of operating systems that respond with respect to time. Quality of real time systems is of at most importance as failure of system can lead to severe results. Quality assurance procedures, methods and standards must be implemented to ensure quality of the system.  Different scheduling techniques are adopted as […]
