Fixing file descriptor leaks
… implement and test a tool for eliminating file descriptor (FD) leaks in programs at run-time. Our tool monitors FD allocation and use. When the allocation of a new FD would fail because a process's entire pool of FDs is already in use, our tool "recycles" (forcibly closes) an FD. The FD to be …

A Data Layout Descriptor Language (LADEL).
<p>To transfer data between devices and main memory, standard C block I/O interfaces use block buffers of type char. C++ programs that perform block I/O commonly use typecasting to move data between structures and block buffers. The subject of this thesis, the layout description language (LADEL), …

Observer based active fault tolerant control of descriptor systems
… often using a standard state space (i.e. non-descriptor) system model approach. These separate FDD/FE and reconfigurable control designs may not achieve desired stability and robustness performance when combined within a closed-loop system.This work describes a new approach to the integration …

Modeling and Prediction of Amorphous Solid Dispersion Formation Using a Molecular Descriptor
… that an ASD will form in PVPva. Since molecular descriptors are mathematical representations of properties of a molecule, it is hypothesized that they can be successfully applied to predict the formation of amorphous solid dispersions. Specifically, the molecular descriptor R3m was investigated …

(i)chromatographic Methods For Solute Descriptor Determinations (ii)ruthenium Substrate-Catalyzed Growth Of Nickel Nitride Thin Films By Atomic Layer Deposition
… The developed models were used to derive descriptor values for environmentally important organic compounds. The accuracy of the developed models and descriptor values were demonstrated by the application to the estimation of standard environmental properties and by comparison with …

A critical evaluation of the contribution of psychographic measures as descriptor variables in the profiling of market segments for a specific industry
Psychographic measures were widely employed in market segmentation studies in the seventies. Psychographics were said to offer marketers quantitative research that resulted in rich descriptive profiles of target segments. The present use of psychographics in segmentation studies has however become …

Video indexing and summarization using motion activity
… domain motion vector based, known and novel descriptors are then described. It is shown that these descriptors successfully estimate the subjective level of motion activity of video clips. Furthermore, the individual strengths and limitations of the proposed descriptors are determined using a …

Novel color and local image descriptors for content-based image search
… focuses on investigating novel image descriptors based on texture, shape, color, and local information for advancing content-based image search. Specifically, first, a new color multi-mask Local Binary Patterns (mLBP) descriptor is presented to improve upon the traditional Local Binary …

Image feature matching using polynomial representation of chain codes
In this thesis the development of a novel descriptor for boundary images represented in a chain code format is reported. This descriptor is based on a truncated series of orthogonal polynomials used to represent a piecewise continuous function derived from a chain code. This piecewise continuous …

Investigation of new feature descriptors for image search and classification
… this dissertation focuses on exploring new image descriptors by incorporating cues from the human visual system, and integrating local, texture, shape as well as color information to construct robust and effective feature representations for advancing content-based image search and classification. …

Identifying Data Centers from Satellite Imagery
<p>We develop two different descriptors which can be utilized to describe satellite imagery. The first, the differential-magnitude and radius descriptor, describes a scene by computing the directional gradient of the scene with respect to a vector field whose solutions are circles around a pixel to …

Investigation on advanced image search techniques
… image search techniques and presents new color descriptors for image search and classification and robust image enhancement and segmentation methods for iris recognition. First, several new color descriptors have been developed for color image search. Specifically, a new oRGB-SIFT descriptor, …

Language Extension in Social Cognition: Personality Impression Judgment as a Cognitive Matching Operation
… language: the process of tying a particular descriptor to a particular experience of a person. It is proposed that this process of verbal meaning extension, especially as manifested in most psychological rating tasks, involves a cognitive matching operation wherein a descriptor is evaluated …
