The Study Of Boundary Layer Control In A Turbopump Diffuser With Fluid Injection, Diego Garcia Pastor

Theses

Future Space Transfer Vehicles (STV) will be required to perform missions (orbital transfer, Lunar/Mars transfer and descents) for which deep engine throttling is needed. In order to do this the turbopumps that propel the Space Transfer Vehicles need to be able to operate at different flow rates. The current state of the art cryogenic fuel and oxidizer turbopump designs do not operate well at off-design flow rates mainly due to stall and flow separation in the diffuser section. The purpose of this Thesis is to analyze the behavior of the fluid in the diffuser and the vaneless and vaned region …

Iterative Morphological Filters And Application In Document Restoration, Yeqing Zhang

Theses

The binary nature of document degradation decides the suitability of morphological methods for restoration. Although the computational burden in morphological filter design can be mitigated by imposing constraints on the filter and employing the morphological filter MAE theorem in an efficient search strategy, the design constraints on the filter limit the performance of single-pass filter. It has been shown that iterative morphological filters can outperform single-pass filters. The investigation of iterative morphological filter design for image restoration is the main contribution of the present thesis. The study of iterative morphological filter design provides the understanding in depth of how filters …

Signal Detection Using Pseudocolor Scales, Hong Li

Theses

Historically, gray scale has been the standard method of displaying univariate medical images. A few color scales have been proposed and evaluated, but have had little acceptance by radiologists. It is possible that carefully desired scales might give lesion detection performance that equals gray scale and improves performance of other tasks. We investigated 13 display scales including the physically linear gray scale, the popular rainbow scale and the other 1 1 perceptually linearized scales. One was the hot body (heated object) scale and the other 10 were spiral trajectories in the CIELAB uniform color space. The experiments were performed using …

An Artist's Guide To Four-Color Printing: A Prototype Of A Guide To Educate Artists About Four-Color Offset Printing, Whitney Miller

Theses

Occasionally artists need to have their artwork reproduced. The problem is that most artists do not understand what is involved in the four-color prepress and printing processes and, because of this, do not know how to communicate with printers. Artists often do not realize it is very difficult to make an exact copy of their artwork when it is reproduced by four-color offset lithography and are disappointed with the final printed product. The objective of this thesis project is to educate artists about four-color printing so they can communicate more effectively with printers. A prototype for a booklet entitled An …

Moving Toward Reconciliation, Paula Boronell
