ABSTRACT The research evaluates the chemical, mechanical and microstructural characterization of an armour steel sourced from a scraped armoured vehicle in order to develop local content in the armouring technology. Chemical analysis, optical microscopy and mechanical tests were employed to examine the microstructural and mechanical properties of a low carbon armour steel. Chemical analysis showed the elemental constituents and the exact weight per percentage of each element present in the t...
ABSTRACT Majority of small scale farmers and homes are still using open-sun and/or non-convective methods for drying due to either high cost of gas/electric dryer or lack of electricity in their locations. These methods are time consuming and exposed the products to rain and contamination. A maintenancefriendly and properly enclosed dryer is therefore desired. The batch kerosene heated dryer was studied and adapted to suit the need of these people. In this work, the heat and mass transfer an...
Abstract Torsional vibration in Internal Combustion Engines is an important phenomenon occurs due to excitation loads, cycle-to-cycle variations results from the force the burnt gases and to change in inerita forces generated by reciprocating parts during convertoin of rotary motion to the linear one . This conversion leads to twist torque on the crankshaft which, in turn, leads to high stresses causing its damage. The importance of the present study stem from the fact that this phenomenon c...
Abstract With the increase in vehicle production and world population, more and more parking spaces and facilities are required. In this research a new parking system called Smart Parking System (SPS) is proposed to assist drivers to find vacant spaces in a car park in a shorter time and save effort. The new system uses sensors to detect either car park occupancy or improper parking actions. Features of SPS include display of available parking spaces, payment facilities and different types o...
ABSTRACT Agriculture is considered as the basis of life as it is the main source of food and other raw materials. This report describes an IOT Irrigation Monitoring and Control system wherein, the user can monitor and control the supply of water from a remote location. The system makes use of a concept called TOT (Internet of Things). This enables the system to be connected to the internet using a Wi-Fi module. An Arduino Uno board was used to send the control signals and connect to the desi...

Abstract aerospace is one of the most developed science all over the world and it is not exclusive to the developed countries. In a country like Sudan with extended boundaries, huge internal resources never profiteered from this technology. There are numerous security problems represent some challenges. The main objective of this study is to design a small microsatellite structure to solve and control those types of problems. Microsatellite structure was modelled using SOLIDWORKS then the st...
ABSTRACT The performance of diesel engines is heavily influenced by their injection system design. In fact, the most notable advances achieved in diesel engines resulted directly from superior fuel injection system designs. While the main purpose of the system is to deliver fuel to the cylinders of a diesel engine, it is how that fuel is delivered that makes the difference in engine performance, emissions, and noise characteristics. The objective of the present work is to evaluate performanc...
Abstract The pumps work differently in terms of performance characteristics when operated in reverse mode to generate mechanical rotational energy driven by the water energy. The performance characteristics related to head, flow rate, specific speed and efficiency have been predicted differently from available conversion methods. Also, the procedure of selecting pump as hydro-turbine varies from different conversion methods. This article presents the methodological approach of evaluating th...
ABSTRACT Cavitation is the appearance of vapor cavities inside an initially homogeneous liquid medium, occurs in very different situations. According to the flow configuration and the physical properties of the liquid, cavitation is the most commonly required one in all the researches on the pumps and flow systems but they are too hard to manipulate with the primary methods. In this research was study the effects of rotational speed (rpm); flow rate (Q); fluid temperature (T) and pressure (P...
Abstract Abrasive Water Jet Machining – (AWJM) become one of popular and growing processes among Advanced Machining Processes. It has high material flexibility and advantages of geometric, and ability to cut materials that are hard to machine using conventional technologies, it reduces the time necessary for secondary operations like programming, tool changing, or clamping. this allows a significant optimization of the overall manufacturing process chain. All these Advantages lead to (AWJM)...
Abstract The highway system of a developed country contains thousands center line kilometers of streets. Such systems consist of asphalt, concrete or composite streets ranging in condition, in recent years, several road network monitoring and maintenance programs have been established in order to monitor the on-going performance of the road network, to predict future road conditions and assess long term needs, to support investment planning and decision making, and to identify rehabilitation...
