This paper presents an algorithm to solve the inverse kinematics problem for a complex wrist structure six degree of freedom (6DOF) robotic manipulator. The last three rotating axes do not intersect at one point and there are off axes in its coordinate frames. The proposed algorithm based on the rotation vector concept, which is also used to describe the orientation of manipulator end-effector. All the possible solutions of the inverse kinematics problem can be obtained by using the proposed algorithm which is tested practically on the MA2000 robotic manipulator.

The average overhead required for producing a scalar result may be reduced by vectorizing dataflow computations. This reduction may lead to eliminating or reducing pipeline starvation during periods characterized by low degrees of parallelism. A dataflow model based on a vector queueing scheme is presented. The model supports parallelism between different activations of vector nodes, and requires less overhead than conventional dynamic models.

Self-organization systems are rapidly emerging as a powerful paradigm for tacking complexity, improving reliability and optimizing performance in several literatures and are widely applied in a number of domains. Obviously, to develop such complex systems need specified technologies as well as systematic approaches, and they should be developed in an engineering way. We argue software engineering for self-organization systems should consider the specific complexity properties of self-organization and should seek effective approaches to model, design, and dep.oy such systems. This paper aims to survey the state-of-the-art of the researches on software engineering for self-organization systems from theory, technology and tool viewpoints, investigate the potential issues and challenges in current researches, and suggest future research directions.

According to some discoveries and analysis results of network measurement for network traffic in recent years [1, 2], this paper has proposed three propositions about distributions of network traffic. To explain these propositions, the shaping effect for network traffic the Internet structures have is pointed out, and the novel concept of shaping operator and a doublemode transition model between self-similarity distribution and Poisson distribution is put forward. Finally, the validity of the shaping function and three propositions are verified by a lot of simulation experiments on NS2.
