Tong-Kong sakura shrimp is one of important fisheries in southwest coast. Tong-Kong sakura shrimp, blue fin tuna and mullet roe are called Three Treasures of Tong-Kong . It brings significant economic benefits for local residents. This research is based on Gordon-Schaefer Model theory that combines with fishery catch statistics and operational cost data. Also, we use these data to discuss open-access fishing ground and dynamically optimal fishing ground of balance status under equilibrium level. Next step is to do stimulation analysis that based on annual fishery catch statistics of sakura shrimp. After stimulation, we can make comparisons of equilibrium values of these two fishing grounds. From analysing fishery catch statistics and fishing resource we may know that it can shows that the management of sakura shrimp tends to dynamically optimal fishing ground, and also can state that the management mechanism of sakura shrimp is an ideal of sustainable management. Then, through the example, we can understand how each variation influences fishing resources and fishing effort of these two fishing grounds. Finally, we simulate fishing resources model of two fishing grounds to show the result. If we don¡¦t manage fishery of sakura shrimp well and keep uncontrolled fishing, not only the fishing ground will become an open-access fishery, but also fishing resources will become extinct. However, once we can manage fishing ground efficiently, it will become a dynamically optimal fishing ground and the fishery of sakura shrimp will develop sustainably.

A simple design methodology of optimal model reference adaptive control (OMRAC) scheme with perturbation estimation for solving robust tracking problems is proposed in this thesis. The plant to be controlled belongs to a class of MIMO perturbed dynamic systems with input nonlinearity and time varying delay. The proposed robust tracking controller with a perturbation estimation scheme embedded is designed by using Lyapunov stability theorem. The control scheme contains three types of controllers. The first one is a linear feedback optimal controller, which is designed under the condition that no perturbation exists. The second one is an adaptive controller, it is used for adapting the unknown upper bound of perturbation estimation error. The third one is the perturbation estimation mechanism. The property of uniformly ultimately boundness is proved under the proposed control scheme, and the effects of each design parameter on the dynamic performance is also analyzed. An example is demonstrated for showing the feasibility of the proposed control scheme.

The purpose of this dissertation is to study the robust control for the smart flexible linkage mechanism. The control of flexible linkage induced inertia force under high-speed rotation is taken into consideration with the system parameter uncertainties such as modeling error, truncation error, and both of control spillover and observation spillover due to the residual modes of structural control problem. Based on the principles of LQ, optimal model following (OMF) and frequency shaping, this study proposes some sufficient conditions of stability criteria for the design of robust controller, respectively. These techniques guarantee that the controlled plant, under both bounded parameter perturbations and model truncation, could remain stable. Meanwhile, searching for the optimal locating positions of sensor and actuator by applying Taguchi method and genetic algorithm (GA) combined technique is further studied. The system is modeled through employing finite element method (FEM), and the limited lower frequency part modes are separated into controlled modes and residual modes. In time domain, at first we design a Luenberger-observer-based robust controller for the finite-dimensional mode plant keeping stability in a specified region. And then, a robust controller with the OMF is designed for the controlled system to achieve the performance as those of the specified optimum model. From the view of frequency domain, the robust controller could also be deigned according to the frequency shaping principle to suppress the exciting effect of higher frequency residual modes, and similarly avoid that the system might be destabilized. Finally, the combination of Taguchi method and GA technique to search the optimal locations for placing actuator and sensor to coincide with the stability and performance requirement is also done. From the computer simulation, the middle point movement of the linkage is obviously well controlled; hence, the designed robust controllers can certainly suppress the affection of parameter uncertainties and the spillover stimulation of residual modes, and can produce satisfactory results.

This dissertation focuses on the investigation and development of an effective prosthetic training and rehabilitation platform with the use of virtual reality to facilitate an effective process to return amputees to the highest level of independence and functioning possible. It has been reported that approximately 10 million people live with a limb loss worldwide, with around 30% being an upper-extremity amputee. The sudden loss of a hand or arm causes the loss of fine, coordinated movements, reduced joint range of motion (ROM), proprioceptive feedback and aesthetic appearance, all which can be improved with the use of a prosthesis and proper training. Current literature has shown prosthetic devices to provide limited function to users in a variety of areas including hand operation, functionality and usability, all which could be improved with proper rehabilitation and training. It has been exhibited that a large percentage of amputees abandon or reject prosthesis use mostly due to limited function and lack of training or knowledge of the device. It has been reported that untrained amputees will adjust their body in an awkward or compensatory body motion rather than repositioning a joint position while performing a task with a prosthetic device. This causes misuse and improper function that has been shown to lead to significant injuries. An effective prosthetic training and rehabilitation regime would be advantageous in returning the patient to the highest level of independence and functioning possible, with proper use of their prosthetic device. A successful training and rehabilitation program would allow an amputee to improve their ability to perform with optimal motion and use all prosthetic control capabilities. This dissertation describes the development of a stick figure model of the user’s motion in real-time and a character avatar animating the individualized optimal goal motions. The real-time model directly corresponds to the user’s motion, with the option to have the character avatar simultaneously animating an optimal goal motion for the user to follow. These were implemented into the Computer Assisted Rehabilitation Environment (CAREN) system (Motek Medical, Amsterdam, Netherlands) to provide real-time visual feedback to the users while performing specified training and rehabilitating tasks. A ten camera Vicon (Oxford, UK) optical motion captured system was used with the CAREN system capabilities to track body and upper extremity prosthetic segments during range of motion (ROM), activities of daily living (ADL), and return to duty (RTD) tasks, with and without the use of the virtual reality visual feedback. Data was collected on five able-bodied subjects and five subjects with a unilateral transradial amputation using their personal prosthetic device. Through investigation and development, a preferred and effective way to display the visualization of the real-time and optimal models were revealed. Testing the subjects with and without the virtual reality visualization, exhibited the effectiveness of providing visual feedback. Results showed subject’s to have improved positing, movement symmetry, joint range of motion, motivation, and overall an improved performance of the series of tasks tested. With the integration of the optimal model visualization, real-time visual feedback, and additional CAREN system capabilities, upper-extremity training and rehabilitation techniques were shown to enhance with the use of virtual reality, through improved task performance, and functional advances. The results of this dissertation introduce an alternative means for clinicians to consider for effectively rehabilitating and training upper-limb amputees. Findings of this dissertation sought to provide useful guidelines and recommendation to aid in the development of a small-scale adaptable option for rehabilitation practitioners and at home use. The techniques investigated in this study could also be applicable for lower-limb amputee, post-stroke, traumatic brain injury, poly-trauma, and other patients with physically limiting disabilities. The techniques investigated in this study are expected to aid in the development of training and rehabilitation procedures for a variety of patient populations, to enhance the effectiveness and assist in improving the overall quality of life of others.

This thesis deals with the personality of prominent lawyer and a political scientist Zdenek Mlynar during his tenure at the Institute of State and Law of the Czechoslovak Academy of Sciences. Mlynar was one of the leading figures and ideologues of the Prague Spring; in the first half of 1968 he was a member of the Central Committee of the Communist Party and later he became its secretary. He was also one of the authors of the 'Action Programme' of the Communist Party, precisely of its political part. Nevertheless his ideological development was not straightforward; he started as a devoted ideologue and dogmatist in the 1950s to become a reformer in the second half of the 1960s. And during that whole time period Mlynar had been employed as a scientist at the Academy of Sciences in the field of the legal theory. For the purpose of this thesis was Mlynar's more than twelve-year long tenure at the Academy of Sciences is divided into three periods: a research assistantship between 1957 and 1959, his tenure as a head of the Department of Theory of State and Law between 1960 and 1966 and then the time of his work on the political reform in 1968, with a special attention being paid to the interdisciplinary team "Development of the political system in the socialistic society" which was initiated and...
