the student Rahim Sadek Majeed from the Department of Mechanical Engineering at the University of Technology, received a PhD for his thesis (Application of the Algorithm of the Automated Robot for Free Navigation based on image processing and the optimal algorithm)
 The researcher focused on the design and implementation of a guided algorithm for the steering of a motorized robot, which restricts the direction of free navigation within a predetermined path with the least errors in the course of tracking the path and overcoming the obstacles fixed and moving without intersection after locating and moving and speed of movement using the image processing method. The first stage consists of four stages. The first phase includes a synthetic nerve control to control the movement of the robot with low energy consumption and less deviations from the desired path. In the second stage, the self-tuning of the neurotransmitter factors is done by using the optimization particle-optimization algorithm. The third stage is the construction of the path according to the specified path and the obstacle locations. The fourth stage scans As part of University of Technology programs for Postgraduate Scholarships and for the promotion of modern competencies at the university, Asst. Prof. Salim Khalifa Kadhim, a lecturer from Control and system Engineering Department at the University of Technology, received his PhD in Biomedical Engineering from the University of Petronas, Malaysia Titled "Numerical and experimental investigation of the effect of induced vibrations on the mechanical heart valve"
 (Diode diffuser) The research involved the use of widely diffused mechanical heart valves (BMHV) to replace diseased original cardiac valves. However, BMHV may fail for certain reasons such as plaque buildup, and damage to blood cells leading to valve heart failure. Previous research has indicated that there are unknown reasons for BMHV failure.
 In this research, one of the possible and unknown causes of valve failure, the effect of induced vibrations (FIV) on the performance of bipolar heart valves and its components, will be investigated. It is also known that blood flow in the artery is a pulsed flow, which can cause vibrations known as induced vibrations.
 To achieve this, a numerical simulation with experimental measurements was performed for the Reynolds blood flow in the interstellar flow, ranging from 114 to 1950, using FSI technique. The numerical model was verified against experimental measurements. From numerical simulation, it was found that the shear stress values in the blood flow in the surface of the LED surface reached high values causing plaque buildup and could cause damage to blood cells especially in the diffused valve area and valve installation areas with LED structure
