The pervasive ‘Afro-pessimism’ of the 1980s and 1990s has given way to an image of Africa that is socially and economically vibrant, politically more open, with an assertive civil societ

Cold War militarization and geo-strategic politics have been replaced by a preoccupation with implementing liberal democratic statehood worldwide, and in this way to promote econo

Linear Control Techniques,gulator (LQR) with loop transfer recovery design (LTR), together with some newly developed design techniques, such as the robust and perfect track ing (RPT) method. We will first introduce the precise problem definitions of these techniques and then provide detailed solutions explicitly constructed

Track Following of a Single-Stage Actuator, smaller, leading to lower error tolerance in the positioning of the head. The controller for track following has to achieve tighter regulation in the control of the servomechanism. Current HDDs use a combination of classical control techniques, such as lead-lag compensators, PID compensators, and n

Design of a Piezoelectric Actuator System,lly reported by Chen .. Piezoelectricity is a fundamental process in electromechanical energy conversion. It relates electric polarisation to mechanical stress/strain in piezoelectric materials. Under the direct piezoelectric effect, an electric charge can be observed when the materials are defo
