Design methodologies of microwawe integrated circuits for satellite telecommunications
… a specific performance such as power, low-noise, linearity, broadband etc. For these reasons circuit design is always a “compromise”, an investigation for the best solution to reach a trade off between the desired performances. This approach becomes crucial in the design of microwave systems to be …

A reduced-order crawler crane model with active control to attenuate the transient vibrations
The nonlinear differential equations describing the motion of a crawler crane in a plane are formulated by applying Lagrange's equation to the system kinetic energy, potential energy and virtual work. The transient response of the crane system due to the vertical drop of the suspended load is …

The influence of high performance matrices on fracture behavior of concrete
… behavior of concrete is investigated. While the linear elastic fracture mechanics (LEFM) concept is not appropriate for concrete, a nonlinear fracture model based on the load vs. load-line deflection and the load vs. crack-mouthopening displacement (CMOD) responses of the three-point bend tests …

High Frequency, High Current Density Voltage Regulators
… are the high current, high di/dt, and stringent load-line requirement. When the energy is transferred from the input of a VRM, through the VRM, then through the power delivery path to the processor, it needs sufficient capacitors to relay this energy. The capacitors' number appears to be …

Advanced Control Schemes for Voltage Regulators
… should be high in order to meet the stringent load-line requirements with the high current and high di/dt, otherwise, a lot of decoupling capacitors are necessary. Capacitors make the VR cost and size higher. Therefore, the VR control method is very important. This dissertation discusses the …
