Computational Design of Prosthetic Hip Implant AL-sanea, Abdulrahman; Omara, Akram; Naresh Kumar, Nitturi; Eltayeb, Megdi - In this study a 2D/3D CAD model of an artificial hip joint was designed using SolidWorks software program. Biocompatible and robust enough materials such as Titanium alloy Ti6Al4V and Alumina ceramic Al2O3 were used in the designing process for such parts of the hip joint. The finite element (FE) method was used to obtain a solution for the stress and strain distribution throughout series of adjacent elements, further the design was analyzed using computer-aided engineering (CAE) software after it was loaded with static loads 250N, 350N, and 450N respectively to check the durability of the design. The stability of the model was verified by static test.

High Speed Low Power Cyclic Redundancy Check-32 using FPGA S. Abdulnabi, Mohamed; Ahmed, Hisham Cyclic Redundancy Check (CRC) is a method used for error detection technique and data integrity. CRC take a block of a message’s bits and divide it by a binary number called polynomial, the result of this division is the checksum that will be added to the message. On the receiver side, the same division will be performed to get the remainder which could be compared with the transmitted checksum if there are no differences that are mean there are no errors. This paper aims to design CRC32 that applied in the Ethernet frame by using Field Programmable Gate Array (FPGA) Virtex-7. Lookup tables and slicing-by-16 algorithm are used together to calculate the CRC32 in parallel. Xilinx ISE used as IDE and synthesis tool and I-Sim used for simulation purposes. The result of this design is 1.250 ns which is the processing time and 102.4 Gbps which is the throughput, furthermore the power consumption is very low as well as the device utilization.

IMPLEMENTATION OF CYCLIC STEAM STIMULATION TO ENHANCED OIL RECOVERY FOR A SUDANESE OIL FIELD: CASE FULA NORTH EAST FIELD Ali Elbaloula, Husham A.; A. Musa, Tagwa - Tertiary oil recovery or Enhanced Oil Recovery (EOR) is the injection of fluids or energy to the reservoir to improve oil recovery and it can be applied at any phase of oil recovery including primary, secondary, and tertiary recovery and its objective is to increase oil recovery from reservoir depleted by secondary recovery such as water flooding. Steam Injection is to inject steam to heat the oil to higher temperatures and to decrease its viscosity so that it will be more easily to flow; cyclic steam stimulation (CSS) consists of three stages and happened in single well, CSS is particularly attractive because it has quick payout, however, recovery factors are low (10-40%) from Original Oil in Place (OOIP). In a variation, CSS is applied under fracture pressure. Fula North Field (FNE) reservoirs are highly porous (~30%), permeable (1-2) Darcy and unconsolidated in nature. the fluid properties include viscous crude with 15 to 17.7 API. Corresponding viscosity are in the range of (727 and 3800) cp at reservoir conditions and the current recovery factor is 3.6 %. The objective of this paper is to illustrate and analyze the performance of CSS phase’s implementation starting from the first pilot up to full field scale through different stages. In this paper overall analysis for the CSS performance implementation including the injection parameters in FNE field will be presented furthermore detail comparison between CSS cycles and cold production discussed. Finally the challenge for this project has been listed; Advanced Thermal EOR Simulator from Computer Modeling Group (CMG) software has been used to propose the location of the new wells and to compare between CSS and Cold case for FNE Field. The result showed that the CSS is very successful and the average oil rate is almost 1.6 times compared to cold production, the CSS only can increase the recovery percent from 32.5 to 34.2% which makes it more attractive method as development scenario for FNE oil field, and the new wells drilled with 100 % success ration.

Design of a Novel X-band Slotted Waveguide Antenna Array with TE20 Mode Feeding Elhefnawy, Mohamed The Slotted Waveguide Antenna Array (SWAA) was introduced since the decade of 40s. This type of antenna array is well known by its reliability and ability to handle large amounts of power and high operating frequencies, so that the SWAA is commonly used as a part of radar systems. This research paper studies the design of a novel X‒band Slotted Waveguide Antenna Array (SWAA) which is excited by TE20 mode. The radiation characteristics of TE20 mode excited SWAA are compared with conventionally designed TE10 mode excited SWAA. The CST Microwave Studio (CST MWS) simulation results show that the SWAA with TE20 mode feeding features high bandwidth, narrow beamwidth, and high gain as compared with TE10 mode fed SWAA. Feeding the SWAA by using TE20 mode instead of TE10 mode results in increasing the bandwidth by 5.7 %, decreasing the beamwidth by 30˚, and improving the antenna array gain by 2.2 dBi higher than the obtained gain with TE10 mode feeding.
