Abstract:

A harmonic drive is a compact, light-weight and high-ratio torque transmission device which has almost zero backlash. Its unique performance features has captured the attention of designers in many industrial applications, especially in robotics. Despite widespread industrial application of harmonic drives, the torque control of this system has not been fully addressed. In this thesis the robust torque control of harmonic drive system is examined in detail.<br>In order to measure the transmitted torque of a harmonic drive and for the purpose of a torque feedback scheme, an intelligent built-in

This thesis focuses on the design issues of the multiple-output boost full-bridge converter, which is constructed by cascading the boost regulator with the inductor-less full-bridge converter. The design of the boost regulator has been proposed briefly with component selection and compensator design. After that, the inductor-less full-bridge converter is analyzed extensively. In the first place, the operation principle of the inductor-less full-bridge converter is introduced. Later, the effect of parasitic resistance and inductance is analyzed in an L-R series circuit model as step-response, w

Abstract:

This thesis proposes a seventh-order 0.05° equiripple linear-phase continuous-time filter employing, for the first time, instantaneous companding. The filter was designed and integrated in a mature bipolar process. The amount of boost (up to 13dB) and group-delay adjustment (+/-30%) are digitally programmable. The DC gain is controllable up to 10dB, and the -3dB frequency (fc) is tunable from 5 to 70MHz. The output swing for 1% THD is higher than 100mVpp, with a 1.5V supply. The filter consumes very low power (5--13mW for fc = 70MHz), compared to state-of-the-art implementations (e.g. 120mW fo

Abstract:

Conventionally, system simulations of induction motor drives use lumped parameters model of the motor. This approach assumes motor parameters to be constant during the entire operation of the drive. Unfortunately, these are known to vary significantly over the operating range of the motor due to factors such as magnetic saturation, skin effects, and operating temperature. The variations in motor parameters affect motor output and control parameters resulting in degraded drive performance. One way of overcoming this problem is by coupling the field model of the induction motor with the drive si

Abstract:

The conventional standard three-phase induction motors cannot operate inherently after the loss of a phase. The two-phase operation of a three-phase induction motor cannot supply the necessary performance in terms of torque and output power in applications that require high reliability such as electric traction applications, and electric ship propulsion. Therefore, one of the means to overcome this drawback is the addition of more phases to the motor, which forms the main focus of this thesis. This research aims to develop the control system of a six-phase induction motor with a single neutra

This thesis analyzes the People's Republic of China's modernization strategy in order to test the hypothesis according to which the "open-door" policy might represent a shift from Marxism to a Neoclassical economy model.

Although it benefits from the fourteen year old SEZs experience, it is argued, Pudong duplicates the flaws inherent to the SEZs and fails to offer advancement over their development.

It was thought that the hybrid's eXWD (electric cross wheel drive) system could make up for this loss of performance.

The fully-pitched winding arrangement is one of the most radical changes in the design of doubly-salient reluctance motors in recent times. By replacing conventional shortpitched windings with fully-pitched windings, the resulting machine has a strong and position dependant mutual coupling between phases. The major torque producing mechanism is due to changes in mutual inductance with rotor position. This enables the windings to be better utilised, and with correct selection of excitation all phases can contribute useful torque all of the time. The increased winding utilisation requires a lowe

Deep foundations such as driven piles are often used to bypass liquefiable layers of soil and bear on more competent strata. When liquefaction occurs, the skin friction around the deep foundation goes to zero in the liquefiable layer. As the pore pressures dissipate, the soil settles.

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2011.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (p. 67-68).<br>This thesis describes the modeling and simulation of a novel electromechanical valve drive known as the MIT EMV. This valve drive allows an engine to achieve variable valve timing which has been shown to produce improvements in engine fuel efficiency. To test this improvement, a reference engine model with fixed valve timing was obtained from the engine simulation software package WAVE® by Ricardo. A model of

Abstract:

As vehicle technologies continue to improve it is becoming more evident one of the last major factors impacting fuel economy left today is the driver. In this study the driver is defined as the operator of a vehicle and the difference between driving styles of the driver and vehicle is defined as aggressivity. Driver aggressivity is proven to have a substantial impact on fuel economy in many studies. Many fuel economy tests have been created, all to measure the fuel efficiency of today's vehicles and their related technologies. These tests typically require that the drivers be trained or exper

Abstract:

Platooning with trucks is showing promising theoretical results in its ability to lower fuel consumption due to reduction in air drag. Currently, Scania is test driving their trucks in convoys in order to evaluate the concept, in terms of driving behavior and actual fuel saving, under realistic conditions. However, due to traffic conditions it is hard to keep the convoys intact for longer routes and therefore the actual fuel saving effect is hard to evaluate. In this thesis, data collected from a fleet of long haulage trucks is analyzed with four different machine learning predictors in order

Abstract:

Systems management represents the set of activities necessary to ensure that information systems function according to user requirements and objectives. Chapter 1 summarizes the management challenges in today's networks and distributed systems. Policy-driven network management is the new management paradigm. Its implementation needs a new information and decision model, appropriate protocols and new hosting and access mechanisms. IETF policy framework and architecture create the support for the deployment of this new paradigm.<br>Consideration of temporal aspects to allow run-time policy confl

Abstract:

The goal of this thesis is to present and demonstrate the feasibility of tool support for view driven process modelling (VDPM). A view represents a well defined issue of concern related to the software process (SP) which has some intrinsic value, such as providing software engineering support. In turn, views offer insight into the process. Software process models (SPM) are important for communicating, analyzing, understanding and improving the software process. SP are difficult to model because they are complex. Using views in VDPM reduces the complexity of process modelling by separating issu

Abstract:

For more than a decade, music information science and musicology have been at what Nicholas Cook has described as a 'moment of opportunity' for collaboration on database-driven musicology. The literature contains relatively few examples of mathematical tools that are suitable for analysing temporally structured data like music, however, and there are surprisingly few large databases of music that contain information at the semantic levels of interest to musicologists. This dissertation compiles a bibliography of the most important concepts from probability and statistics for analysing musical

Abstract:

The displacement and deformation of brain tissue is a major source of error in image-guided neurosurgery systems. This thesis presents the design, implementation and validation of an image registration algortithm to detect and correct brain-shift using pre-operative MR images and intraoperative Doppler ultrasound data. The registration algorithm uses segmented vessels from both modalities, and estimates the displacement using a modified version of the iterative closest point (ICP) algorithm. The least trimmed squares (LTS) was used to reduce the number of outliers in the point matching procedu
