Abstract:

Current efficiency measurements of variable hydraulic axial piston pumps are performed with the displacement system locked at maximum volume, thus without the controller. Therefore, the controller’s effect on the efficiency is not quantified at state of the art measurements. Former research on control systems mainly focused on the dynamic behaviour. This paper aims to quantify the losses in the displacement and control system and to research the dependencies of those. Therefore, a test rig is built up at IFAS to measure the control power of displacement controlled pumps. Furthermore, a simulat

Abstract:

The efficiency of electrical machines carries a global impact because they fulfill about three-quarters of global electrical energy consumption. Its improvement requires a sound knowledge of energy loss properties of magnetic materials used in the core of electrical machines, especially non-conventional supply conditions, such as non-sinusoidal, high induction, alternating (1-D) and rotating (2-D) flux waveforms that have been posed with the incorporation of new electronic devices and materials in the systems. For these reasons, novel theoretical models and experimental techniques need to be d

Abstract:

Evolutions in integrated circuit technology require the use of a high-frequency synchronous buck converter in order to achieve low cost, low profile, fast transient response and high power density. However, high frequency operation leads to increased power MOSFET switching losses. Optimization of the MOSFETs plays an important role in improving converter performance. This dissertation focuses on revealing the power loss mechanism of power MOSFETs and the relationship between power MOSFET structure and its power loss.

The Fontan repair is a three-stage palliative surgical procedure for single ventricle congenital heart diseases, ultimately resulting in the right heart bypass.

Over the years several modifications have been suggested, ultimately leading to the total cavopulmonary connection (TCPC), which is the current procedure of choice.

Abstract:

Access to reliable electric power is considered by the developed world to be a minimum requirement for a reasonable standard of living. In addition to meeting a fluctuating demand, the modern electricity industry must now integrate intermittent generation sources like wind into the grid. Reserve margin allocation (RMA) for an acceptable loss of load expectation (LOLE) allows traditional generators to maintain grid reliability in the presence of small penetrations of wind energy. However, traditional RMA over-allocates the reserve capacity in the presence of short-term intermittency mitigation

Thus, the energy consumption of the battery-electric truck needs to be analysed in detail, and the differences in the conventional powertrain, recuperation by regenerative braking during driving and charging during standing, need to be considered.

Abstract:

Titanium and its alloys have been widely used in oral implantology due to their mechanical properties, corrosion resistance and biocompatibility. However, under in vivo conditions the implants are subjected to the tribocorrosion phenomenon, which consists in the degradation mechanisms due to the combined effect of wear and corrosion. This process contributes to limiting the life span of the implant and may generate clinical problems in patients as metallic ions are released. Another cause of dental implant failure may be the loosening of the implant as metal does not promote osseointegration.

After that, the plant with main RCS and PXS components was modeled and the steady state calculation was implemented to acquire 100% rated power opera

博士<br>國立暨南國際大學<br>電機工程學系<br>99<br>This thesis focuses on the analysis and design of low-power CMOS receiver front-ends for ultra-wideband (UWB) systems, 60 GHz low-insertion-loss CMOS bandpass filters, and 60 GHz high efficiency power amplifier. In the first half of this thesis, we discuss the analysis and implementation of an ultra-low-loss transmission line, a low-power DC~10.5 GHz distributed low noise amplifier (DA), and a number of matrix low-power distributed low-noise amplifiers (LNAs) in the CMOS technology. In the second half of this thesis, the implementation of a number of low-power

To handle the Fukushima-like conditions, Taiwan Power Company proposed the Ultimate Response Guideline (URG) to ensure the NPP safety. The purpose of this mitigation strategy is to keep the fuels under water. The current criteria are listed as follows: (1) The Peak Cladding Temperature (PCT) is below 1088 K (1500°F) for Station-Blackout (SBO) and below 1477 K (2200°F) for loss of coolant accident (LOCA). (2) The maximum thickness of the claddin

Abstract:

abstract: As the world becomes more electronic, power electronics designers have continuously designed more efficient converters. However, with the rising number of nonlinear loads (i.e. electronics) attached to the grid, power quality concerns, and emerging legislation, converters that intake alternating current (AC) and output direct current (DC) known as rectifiers are increasingly implementing power factor correction (PFC) by controlling the input current. For a properly designed PFC-stage inductor, the major design goals include exceeding minimum inductance, remaining below the saturation

Abstract:

In this thesis, we investigate two different system infrastructures in underlay cognitive radio network, in which two popular techniques, cross-layer design and cooperative communication, are considered, respectively. In particular, we introduce the Aggressive Adaptive Modulation and Coding (A-AMC) into the cross-layer design and achieve the optimal boundary points in closed form to choose the AMC and A-AMC transmission modes by taking into account the Channel State Information (CSI) from the secondary transmitter to both the primary receiver and the secondary receiver.

Abstract:

In recent years, the electric power industry around the world is changing continuously due to transformation from regulated market structure to deregulated market structure. The main aim of the transformation of electric supply industry under open access environment is to overcome the some of the limitations faced by the vertically integrated system. It is believed that this transformation will bring in new technologies, integration of other sources of energy such as wind, solar, fuel cells, bio-gas, etc., which are self sustainable and competitive, and better choice for the consumers and so o
