Abstract : In general, it is difficult to automatically detect faults within large-scale engineering plants early during their onset. This is due to a number of factors including the large number of components typically present in such plants and the complex interactions of these components, which are poorly understood. Traditionally, fault detection within these plants has been performed through the use of status monitoring systems employing limit checking fault detection. .

Abstract : The aim of this thesis can be divided into two main parts. In the first part an algorithm to solve the inverse kinematics problem of a complex structure robotic manipulator based on the rotation vector concept is presented. Solution of the inverse kinematics problem of the robotic manipulator represents one of the problems in the field of the robotic systems. In the proposed algorithm the orientation of the gripper is described with the aid of the rotation vectors too.

Abstract : In the mobile radio environment, signals are usually impaired by fading and multipath delay spread phenomenon. In such channel, severe fading of the signal amplitude and Inter-Symbol Interference (ISI) lead to unacceptable degradation of the system error performance. It is expected that Orthogonal Frequency Division Multiplexing (OFDM) is capable of providing very high data rate with strong robustness of multipath delay spread, which make that ISI is no longer a problem.
