H-infinity Based Active Queue Management Design for Congestion Control in Computer Networks†

Mr. Karam Samir Khalid; Assist. Prof. Dr. Hazem I. Ali

Volume 14, Issue 3 , December 2014, Page 1-9

  Abstract – In this paper the design of robust Active Queue Management (AQM) for congestion control in computer networks is presented. The Ant Colony Optimization (ACO) method is used to tune the parameters of PID controller subject to H-infinity constraints. The nonlinear dynamic model for multiple ...  Read More ...

Static Stability Analysis of Hexagonal Hexapod Robot for the Periodic Gaits†

Hind Z. Khaleel; Dr. Firas A. Raheem

Volume 14, Issue 3 , December 2014, Page 10-20

  Abstract –Hexagonal hexapod robot is a flexible mechanical robot with six legs. It has the ability to walk over terrain. The hexapod robot likes insect so it has the same periodic gaits. These gaits are tripod, wave and ripple gaits. Hexapod robot needs to stay statically stable at all the times ...  Read More ...

State Space Parameters Estimation Using Online Genetic Algorithms †

Saad Jabbar Abbas; Alexander N. Grachev; Ali Hussein Hasan

Volume 14, Issue 3 , December 2014, Page 21-29

  Abstract –Accurate on-line estimates of critical system states and parameters are needed in a variety of engineering applications, such as condition monitoring, fault diagnosis, and process control. In these and many other applications it is required to estimate a system variable which is not easily ...  Read More ...

Abdulmohaimen B. Kassim; Asst. Prof. Dr. Shibly Ahmed Al-Samarraie; Prof. Dr. Waladin K. Sa

Volume 14, Issue 3 , December 2014, Page 30-41

  Abstract –In this paper, a mobile manipulator consisting of four degrees of freedom (4-DOF) robotic manipulator mounted at the top of a mobile platform (front point) of a mobile robot with four differential drive wheels is presented. A mobile manipulator combines the dexterous manipulator capability ...  Read More ...

Development of Model Predictive Controller for Congestion Control Problem †

Dr. Amjad J. Humaid; Dr. Hamid M. Hasan; Dr. Firas A. Raheem

Volume 14, Issue 3 , December 2014, Page 42-51

  Abstract— Nowadays congestion in computer networks is pointed out as an important and a challenging problem. TCP (Transmission Control Protocol) has the mechanism to avoid congestion in computer networks. TCP detects congestion by checking acknowledgements or time-out processing and adjusts TCP ...  Read More ...

Modified On-Line RLS Identification for Condition Monitoring †

Dr. Mazin Z. Othman; Shaima B. Ayoob

Volume 14, Issue 3 , December 2014, Page 52-58

  Abstract – The Recursive Least Squares (RLS) is usually utilized in control applications as in self-tuning strategy to estimate the plant discrete-time transfer function. Furthermore, it can be used as a tool to continuously monitoring the operating condition of the plant under control. However, ...  Read More ...
