this research focuses on determining the presence of malaria and proves the relationship between the subsystems Red and dispersion angle, absorption, and the presence of hemozoin. All readings were taken from Ibrahim Malik Hospital tested by prototype, with total readings 40. The total of non-malaria was six. The readings are divided into two parts: negative readings were thirty four and positive readings are 6 Readings. The scattering angle depends on the absorption of the malaria parasite. The detection accuracy of our system is determined to be 95%, these are Male results but unfortunately all reading for females is zero.

The primary aim of total hip replacement procedure is to relieve joint pain and to reset normal joint function as far as possible. This study aims to design hip implant with optimum combination of dimensions and material with acceptable range of motion ROM. By utilizing of existing computer-aided design (CAD) to generate 3 Dimension model of hip joint. This in order to identify the ideal prosthesis size and position, based on Finite Element and ROM analysis. Further this study providing groundwork for future development of using of design parameters and component positioning for improve the Pre-surgical planning. 3-D hip implant model was designed by using solidworks package, and then finite element analysis was performed. Component parameters included oscillation angle ($Theta $), cup abduction $alpha$), cup anterior opening ($beta $), the angle of the femoral neck component from the horizontal plane (a) and the femoral neck anteversion was used to calculate ROM by using mathematical equations applied on Matlab. Depending on ANSYS and Matlab results model was modified and improved until arrive to acceptable fimal design.

In this paper a new method, Optimal Path from Source to Sink Node (OPSSN), is proposed for achieving the Quality of Service (QoS) in terms of packet delivery reliability and better energy consumption in Wireless Sensor Networks (WSN). Routing in WSN has more expected node failures than the traditional networks; so to establish a routing protocol which supports QoS in WSN, requires considering the reasons for node failure to improve network performance. In case of failure (node failure or link failure), this method will offer automatic adaptation to dynamic linking and low processing overhead by choosing the default path through intensive nodes. This method increases the number of spare neighbors for original nodes which are preserved for data transmission through them, to be used in case of failure. This algorithm is simulated using MATLAB. Results showed that OPSSN achieved better performance compared to LEACH in terms of network life time, packets received at Base Station (BS), number of Cluster Heads (CH) per round, and total energy consumption.

The traditional type $x$ inverted pendulum is highly unstable, nonlinear and challenging system. The paper stabilizes the $x$ inverted pendulum through adaptive gain scheduling PID algorithm. The $x$ inverted pendulum is modeled based on Lagrange's approach. The performance of proposed controller is verified via various simulation works, which include disturbance and variation of parameters with time. The proposed controller is benchmarked with a conventional PID controller. It's found that the gain scheduling PID controller reduces the transient response 15.5% with respect to the traditional PID controller.

Zinc Oxide (ZnO) nanoparticles in powder form were synthesized through the hydrothermal method. The structural properties were investigated using X-Ray diffraction (XRD) and Fourier Transform infrared (FTIR) spectroscopy. XRD pattern showed that the structure of ZnO is to be crystalline, while FTIR and EDX studies confirmed the formation of ZnO functional group. The optical band gap energy was obtained using UV-VIS-NIR diffuse reflectance spectroscopy. The obtained band gap was approximately 3.38eV this attributed to semiconductor behavior. The Dye Sensitized Solar Cells (DSSC) were constructed from Zinc oxide (ZnO) nanoparticles using two different types of substrates, the efficiency was found to be 1.1% for ITO-ZnO, which is almost four times the value of the efficiency of FTOZnO which was found to be 0.3%. The fill factor (FF) was calculated for both solar cells and was found to be approximately 0.68 from ITO-ZnO and 0.6 for FTO-ZnO.Dye sensitized solar cells (DSSC) were constructed, using drop casting method from ZnO nanoparticles dissolved in ethanol and evenly distributed on fluorine doped tin oxide (FTO) and indium doped tin oxide (ITO) substrates. Rodhamine B dye was used as the dye sensitizer for both cells, then the fill factor and efficiency were found for both cells

In Geographical Information System (GIS), digitizing is an exhausting and time consuming process which is used for digital mapping and map updating. Popularity of mobile services and autonomous vehicles technology based on roads network increase the need for road automatic digitizing. Last years, deep-learning gave excellent results on roads segmentation from aerial and satellite imagery [1], that highlighted the automatic digitizing. In this paper statistical method is applied to extract roads from segmented images, and tested with images for three different scenes and gave an average accuracy of 86 percent.

As the big data and application complexities increase, the dynamic performance optimization is becoming a very significant issue. Auto-tuning of the execution of applications has gained a lot of attention recently. However, the exploitation of the dynamic behavioral changes in performance optimization still represents a challenge. This paper proposes a phase-based optimization approach by utilizing the dynamic behavioral changes in applications. This approach aims at enabling each application’s phase to adapt its resource usage based on the dynamic needs of the resources during its execution. Through a priori and posteriori knowledge of the application, operating systems could expose the characteristics of the application’s behavior and the actual resource requirements of each phase. The results of the comparative evaluation with a previous work show, significant improvements in performance with less resource usage, and more convergent results which guarantees the quality of service.

This paper presents the mechanical, electrical and electronic design of a smart multi-function air conditioner (SMAC). SMAC has three tasks and three ways of control besides three ways of power supplies. The first SMAC task is working in Emergency situations, In case a fire happened in the room there is a sensor will detect the smoke and then air suction will work. The second task is cooling the air using the principle of water air conditions. Third task is heating air using a DC electrical heater, all the three previous tasks can work with three power sources (batteries, solar panel and the general electricity) the general electricity will be converted from AC to DC as input to the air condition because all the system of this air condition works with DC. Also it has three ways of controlling mode, the first way of control is manual control by using keypad board, second by using remote control and third by using internet.All above mentioned scenarios and tasks as well have been tested and verified successfully.

This paper introduce a design and simulation of VHF yagi-uda antenna array to be used in radar application. A single folded dipole yagi-uda antenna is simulated and optimized at 165MHz then a yagi uda antenna array with two rows, each row has 6 elements is designed and simulated. The same array is analyzed by introducing a phase shift between the two rows and with using two different elements spacing, $0.5 lambda$ and $0.7 lambda$. Simulation is done using matlab, and parameters of directivity and side lobe levels are investigated for each array. From simulation results, as the distance between antenna elements is increased from $0.5 lambda$ to $0.7 lambda$, the directivity is increased, side lobe level in azimuth is increased and side lobe level in elevation is the same. Also, rotating the beam of the array through a phase shift of 65 degree will not affect azimuth side lobe level but in contrast, elevation side lobe level will increase and the directivity is reduced by a small amount. Also in this paper, blake chart is drawn for the proposed VHF yagi-uda antenna array. The maximum free space range have been taken to be 300 km, 0 degree tilt angle and for the antenna height, two heights have been used 2.7 meters and 4.7 meters, the chart have been investigated for each antenna height and for both element spacing, $0.5 lambda$ and $0.7 lambda$, with and without a phase shift between the rows of the array.
