Fitness, Flexibility, and Suspension: An Aquatics Facility on Washington, D.C.'s Southwest WaterfrontBiesiadny-Mrstik, Michelle Marie 02 July 2004 (has links)
To create a legible building, the structure's form must describe and reinforce the mission of the organization that inhabits it. This proposal for a regional competition, training and recreational aquatics facility demonstrates ideas of physical fitness through an exploration of muscles, cables, tension, joints, and bones. The building is part of a larger urban strategy for redeveloping the Washington Channel waterfront in Southwest Washington, D.C. Early images of transformed beach glass, thread, and basswood generated the inspiration for the basic architectural components: the wall, the columns, and the suspended jewels. The following document gives definition to the basic elements. / Master of Architecture

Development of a New High Speed Cable-Based Planar Parallel ManipulatorSun, Nan Nan January 2012 (has links)
Industrial robots and automation technology have advanced rapidly in the last several decades. New
types of manipulators that uses parallel mechanisms are becoming more popular due to their high speed
and high stiffness. This thesis focuses on a sub-class of parallel manipulators that uses cables to replace
rigid links for further increase in speed. The design strategies in this study were expanded from research
works by Khajepour. Behzadipour, and Edmon Chan. This thesis presents analysis and development of a
new cable-based planar parallel manipulator that is based on a previous prototype built by Edmon Chan.
The new manipulator design added a new rotational DOF to the end-effector, and the number of
cables are doubled in order to increase the stiffness. New methods for kinematics and dynamics analysis
are formulated to make the procedure more systematic. A new mathematical formulation for stiffness
matrix of the end-effector is presented. The resultant stiffness matrix is equivalent to the stiffness matrix
formulated by Behzadipour. Additional stiffness analysis is conducted on valid range of stiffness
calculation and comparison of different cable configurations. A multi-objective optimization problem is
formulated in order to search for the best set of design parameters for the manipulator, and it is solved
with an exhaustive complete search method.
A physical prototype of the manipulator is modelled and manufactured with the help of partners from
Conestoga college. Experiments with the manipulator show that more powerful motors are needed to run
the robot at full speed. Motor torque measurements show that the dynamics analysis of the manipulator is
valid. Stiffness of the manipulator is measured by applying external force to the end-effector, and it is
shown to be strong. The manipulator is able to demonstrate a sort and pick-and-place operation at 60
cycles per minute while running at 70% of the maximum speed, with an acceleration of 2.8 g and velocity
of 4 m/s.

A Study on the Regulation for Convergence of Telecommunication and Cable TV Industries -Sampling European UnionLin, Jia-Hung 12 June 2001 (has links)
THESIS ABSTRACT
A Study on the Regulation for Convergence of Telecommunication and Cable TV Industries -Sampling European Union
Audio, video and data are transferred by different channels traditionally. Therefore, there are diverse industries such as telecommunications, cable TV etc. But now the boundary between industries is ambiguous which is affected by technology development. This phenomenon makes it possible that competition exists between different industries. Moreover, it enhances the opportunities of convergence of industries and operation across industries. However conventional regulation defines regulatory scope according to products, services or technology. But changes of technology and market make conventional regulation unsuitable to current environment. Hence we should take a new regulation framework adapted to new market and development.
European Union had involved these issues since 1980s and submitted a regulation framework suitable for future situation. Therefore, the researcher describes the roles and functions of relating authorities of E.U. and demonstrates the concrete implementations in response to convergence.
Afterward, the researcher analyzes E.U. regulation by two perspectives: regulation authorities and regulation measures. From regulation authority perspective, the roles and attitudes about operation process are observed. From regulation measure perspective, these measures will be analyzed by goal, type and strategic level.
Finally, the researcher tries to search for a general regulation framework for Taiwan¡¦s reference. In addition, after Taiwan¡¦s entrance to WTO, the process of negotiation between countries of E.U. could be a reference for Taiwan¡¦s authority to deal with international affairs.
