Amplifying the Significance of Systems Theory

In system theory organizations are viewed as closed or open systems. An open system interacts with the environment for its sustainability. The closed system does not interact with its setting consequently its behavior depends largely on internal dynamics of its parts. The centricity of an open organizational structure is one created and empowered to learn and change very fast to successfully achieve desired goals. However open systems need to embrace change as follows: transform inputs of energy and information to produce the products demanded by the customers, transact with key stakeholders to access resources, regulate system behavior to achieve stable performance, and adapt to continuously changing high velocity competition to increase productivity.

Antropomorphe Robot with 4 Degrees of Freedom for Didactic Use

The work relates to practical conceivement and achievement of mecanical and action structure of an antropomorphe industrial robot with 4 freedom degrees + gripper, conceived at “C. Brâncuşi” University – Târgu Jiu for didactical usage. The work presents cinematical chain and building solutions used for mechanical structures, actionand comand systems and speed regulate system of an industrial robot.

Design of the AC Motor Speed Regulator Controlled by ARM

The paper proposes an AC motor speed regulate system based on ARM. The system's hardware core is the LPC2131, in which processor successfully transplanted the μC/OS-II real-time operating system. In the form of task, each functional module of the system can be achieved on the processor LPC2131.The system is simple hardware circuit, software module to realize the complex control algorithms. Experiments show that the multi-task classify program is feasible on the embedded real-time operating system based on LPC2131 and μC / OS-II, it ensures the system's real-time, has good multi-task operating and transferring characteristics and improves the system stability and reliability.
