Toward A Model Of Instruction For Architecture Design Studio, Garry Allen Perryman
Toward A Model Of Instruction For Architecture Design Studio, Garry Allen Perryman
Theses
This inquiry addresses some fundamental issues raised in a debate over the effectiveness of architecture studio instruction. It argues that as currently structured the studio's potential effectiveness is often unrealized, because of the paucity of standardized educational resources and instructor's lack of training in educational theories of instruction. This has resulted in instructional planning that is seldom structured on educational theory or research. It is also argued that in order to maximize it's effectiveness, beginning studio instruction must be premised upon a theory of instruction which includes specifying explicit instructional goals and objectives and that this would create a more …
Robotic Arms With Flexible Links As The Links Approach Rigidity, George A. Downes
Robotic Arms With Flexible Links As The Links Approach Rigidity, George A. Downes
Theses
The dynamics of single link flexible robotic arms are modeled using the Bernoulli-Euler beam equation and Lagrange's equation. The Bernoulli-Euler beam equation derivation is reviewed and is studied in the limiting case as the flexiblity approaches zero. Using the Bernoulli-Euler beam equation, a procedure is developed to calculate the position of the endpoint of a link given the displacement, slope or curvature of any point on the link. Also a procedure is developed to calculate the minimum Young's modulus of elasticity, E, given a specified endpoint displacement tolerance.
A rigid link model based on Lagrange's equation and a flexible link …

The Study Of Paper Surface Efficiency, Wandee Charoenpholphibool
The Study Of Paper Surface Efficiency, Wandee Charoenpholphibool
Theses
Paper surface efficiency (PSE) is a response resulting from the combination of paper gloss and oil absorptivity. A review of previous studies regarding the effect of paper surface efficiency on printed process color appearance is presented. This previous work related densitometric responses to PSE in terms of hue error and grayness. This current study investigated the PSE response in a similar manner, but densitometric responses were replaced by colorimetry. The colorimetric terms used were chroma (C*), huedifference (AH*), and lightness(L*). These correspond to hue error and grayness of the densitometric responses. Simple linear regression models relating the PSE and each …

A Shift Variant Filter Applied To Edge Trace Analysis, David C. Johnson
Theses
A shift variant filter that automatically locates edge toe and shoulder points was used to reduce the noise in the plateau regions of simulated edges having uncorrelated noise. Edges were generated from Gaussian and triangle spread functions and represent edges produced by linear imaging systems only. Versions of these having flare were also used. For comparison a simple "chop" filter was applied to the same edges. Optical Transfer Functions were generated from the 12 categories of edges, ie. unfiltered, shift variant filtered, and chop filtered for each edge type. Modulation transfer functions of these were compared with MTFs of noiseless …
Determination Of Image Quality For Added Noise As A Function Of Spatial Frequency, Yun-Ching Kuo
Determination Of Image Quality For Added Noise As A Function Of Spatial Frequency, Yun-Ching Kuo
Theses
The noise in color images which is referred to as chromatic noise represents a distribution within three spectral bands and contributes to chromatic and achromatic visual effects. The chromatic noise depends very strongly on the spatial frequency response of the visual system. Therefore, this study characterizes the variation in perceived chromatic noise level and generates the noise field to add to the color image samples. From these degraded images, we found that noise in low spatial frequencies is much more disturbing than in the medium and high spatial frequency regions. The perceived quality scales of the modulated chromatic noise images …
