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...

Respondents have selected using simple random sampling technique. The responses were entered and analyzed by using SPSS v11. The findin...
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...
Abstract: Through centuries, the man try to optimize jobs, and reduce the costs. In transportations system, the compact one is more desirable. In this research the sand pneumatic conveying system, used in Garri-4 power plant CFB (Circulating Fluidized Bed) boiler, a problem of high rate erosion studied. And the research aiming to find optimum and reliable solution for it. Experimental test done by using sand-blasting machine to simulate and to test the proposed solution, which is the change ...
ABSTRACT A PLC is a digital computer used to automate electromechanical processes. PLC is frequently used when implementing automated control, which is an important part of many modern industries. This research is based on monitoring Level Temperature Pressure Flow and water cut of crude oil in the vessel by using ABB Programmable Logic Controller . Automatic control of crude oil in vessel can work continuously and can provide accurate quantity of crude in less time. In such process there is...
ABSTRACT The performance of Butan-1-ol (BTU) on the pitting corrosion inhibition of austenitic stainless steel (Type 304) in dilute sulphuric acid contaminated with recrystallized sodium chloride was investigated with the aid of potentiodynamic polarization technique. Corrosion potential, pitting potential, passivation potential, nucleation resistance, passivation range, passivation capacity measurements and potentiodynamic analysis were used to assess the pitting resistance characteristics ...
Abstract This research concerns with the energy resources in Sudan. It includes the steam plants, their unplanned outage problems. The study conducted on Dr. Sharief power station in Khartoum north. The research is studied the station problems occurring during the period (Jan 2011 to Dec 2015), the maintenance program procedure and management method description. Losses resulting from unplanned outage were calculated. The rest of maintenance was not calculated because there were no enough dat...
ABSTRACT Failure of engineering components in service, especially in marine applications, has recently been a major global concern, and corrosion resulting from biofouling has been the primary source of these failures. Ultimately, biofouling and corrosion are detrimental to the lifespan of parts in service. Thus, there is a need to develop protective coatings which are highly resistant to the biofouling-corrosion system. This study developed affordable, eco-friendly and durable bi-phase of Zn...
ABSTRACT African nations have been characterized by conflicts, total war, slave trade, poverty of the highest order, corrupt leadership, undeveloped infrastructures, indisciplined society, we can go on to mention as many as the vices that estranged the continent. It is an irony to see all these in African continent, where civilization of the world began. For all these calamities that befell Africa, I sometimes wonder, if that is why the observation of our God in Genesis 6:5 was made. “The L...
