This is done by using Artificial Neural Network technique to select the weight, and ...
Abstract Sustainable concrete provides a considerable solution to the increasing cost of conventional concrete production in the world. Though, it is generally described as cheap, however it’s design and cost implications for low income communities needs to be evaluated. Hence, this paper evaluates the production of sustainable concrete and its cost implication in Nigeria. Experimental design of high strength concrete made with steel fibre and bamboo fibre as reinforcement having a targete...
Most variable speed wind turbines have pitch angle control mechanisms and one of their objectives is to extract maximum power from available wind speed. By adjusting pitch angles of wind turbine. In this research the use of pitch angle control for wind turbine equipped with self-exited induction generators (SEIGs) and power electronic converters is presented. To extract the maximum available power from the wind, the wind turbine is controlled using pitch angle control based on power sign...
Vaccines container detector based on gold nanoparticles was synthesized according to plant seeds extract method which is simple, efficient, economic and environmentally In this study two types of seeds were used to produce gold nanoparticles: black seed (Nigella sativa) and fenugreek seed (Trigonella foenum graecum) extracts as reducing agent to reduction of gold precursor of Au+3 (HAuCl ) to Au 0 in the presence of a stabilizer (Gum Arabic) which keeps nanoparticles apart, thus avoid...
ABSTRACT Solar energy applications being developed to assist in limiting the extent of climate change through low-carbon technologies, rely on the natural environment that may be sensitive to changes in the climate, resulting from rising carbon emissions. Climate models are essential to predict the future of solar irradiance fields needed for long range planning of solar energy use. Despite the wide use of numerial models on precipitation and agriculture, their applications on measuring the ...
The standard IEC61850 is the first standard that considers all the communication needs within a substation. The main goal of this standard is to support interoperability of IEDs, to allow IEDs from different manufac turers to operate on the same network sharing information and commands. This thesis discusses challenges for implementing the new communication architecture of IEC61850. The aim of this thesis is to demonstrate how an IEC 61850 source code application running at station leve...
The main drawback of Orthogonal Frequency Division Multiplexing (OFDM) systems is the high peak-to-average power ratio (PAPR), which leads to a significant reduction in power efficiency. In this research discusses different PAPR Reduction techniques in OFDM. Techniques like clipping, Selective Mapping (SLM), Partial Transmit Sequence (PTS) based different modulation and different channel. Clipping technique is simple, SLM reduction technique; generation of phase sequence is very random...
It is very important to protect country's borders from intruders who carry out illegal activities such as terror attacks or smuggling of people or their properties. Borders should be monitored to avoid the above-mentioned risks by using border surveillance system which consists of ground surveillance radar and camera to achieve this mission. To perform the monitoring, signals are sent from radar to the microcontroller, according to target location, in order to move the camera to capture...
ABSTRACT This research is focused at designing of water storage facilities of size 875,000 litres (750,000 litres for underground water storage, and 125,000 Litres for elevated steel tank) of treated wastewater and its transmission system for the storage and re-use of treated wastewater. The project is aimed to structurally design water storage facilities and its transmission system from the reservoir to the overhead tank for the re-use of treated wastewater in Covenant University. The desig...
The ejector is a device that been used to release the vapor and gases, or used to suctioned fluid from place to another been pumped to. Power plants condenser need this equipment to release gases and uncondensate steam, the ejector available in Kosti Thermal Power Station (KTPS) is not sufficient for produce the required vacuum for releasing gases and vapor. In this research the ejector was studied and some modifications to it like change is done the in throat length and divergent lengt...
Sickle cell disease (SCD) is the most popular inherited blood disease, that red blood cells change its shape form circular shape to sickle shape and loses its main job which carries oxygen throughout the body. The watershed segmentation method has become highly developed for automated analysis of overlapping red blood cell microscopic images. The aim of this work is to suppress over segmentation problem which is a major drawback of the watershed algorithm. The experimental resultsshowed...
IPv6 is the next generation in internet protocol. It is developed by the Internet Engineering Task Force (IETF) to provide better performance and also to provide new services in comparison to IPv4. It is intended to serve for sufficient IP address space to meet the present Internet growth. Security attacks have been common across the Internet, therefore in order to protect IPv6 networks from security attacks; IPSec has made an inbuilt component of IPv6 to ensure the integrity, authentic...
A wireless sensor network is composed of a large number of sensor nodes and a sink. In the wireless sensor networks the main problem is limited battery life used by sensor nodes and the mobility of the sink nodes in the network. To avoid this problem, protocols with mobile sinks were proposed. They helped in achieving load balancing and uniform energy consumption throughout the network. This research aimed to concentrate on the dynamic requirements of the mobile sink by providing an ove...
ABSTRACT The utilization of lignocellulosic biomass as feedstock for the production of fuel ethanol has attracted considerable interests in the last few decades. The emergence of new technologies has provided hope for fuel ethanol potential uses. Lignocellulose is a valuable alternative energy source. The enzymatic hydrolysis of lignocellulosic biomass is constrained due to its complex structural features, so pretreatment is important to enhance its enzymatic digestibility. In this study, th...
ABSTRACT Numerous failures and eventual losses in the chemical industry have been traced to corrosion processes. Failures resulting from the inability of metals to support designed load requirements because of losses imposed by corrosion effects can be combated economically through the use of chemical inhibitors. Despite the fact that synthetic inhibitors are effective, nonetheless they are associated with problems of toxicity, disposal, litigation and enormous costs. In order to protect the...
