Microthruster Experimental Analysis
<p>The purpose of this study was to design an experimental apparatus that could accurately test and measure the thrust efficiency of conical shaped microthrusters with varying divergence half angles. The experimental apparatus measured the thrust of micronozzles for various feed pressures in vacuum …

Experimental analysis of database query languages
… hypotheses is emphasized throughout, and experimental guidelines are proposed as a means of evaluating the languages. The purpose of the paper is twofold: to develop design principles for the empirical investigation of query languages, and to apply these principles to the evaluation of …

Experimental analysis of beam B-Dot sensors
… signals were examined during the experiment. The experimental calibration of the B-dots, and the resulting certified accuracy of their remote, non-intrusive measurements of relativistic electron beam parameters should have a wide range of application to many other electron beam machines.

Computational and experimental analysis of plant microRNAs
… Seven previously unknown miRNAs families were experimentally verified, bringing the total number of known miRNA genes in Arabidopsis to 92, representing 22 families. We expanded the range of functionalities known to be regulated by miRNAs to include F-box proteins, laccases, superoxide …

Analytical and experimental analysis of fireplace performance
… design. These values were then compared to experimental data. Four calculations were run under various conditions of inlet air, heat source, and baffie temperatures. The heat source temperature ranged from 1000 to 1300 K. The temperatures predicted by the computer model were within 1 to 28 …

Numerical and Experimental Analysis of a TurboPiston Pump
… the actual pump while running. Additionally, an experimental rig was designed to investigate the performance of the first generation valve on the TurboPiston Pump known as the flapper valve. Means to improve the hydrodynamic performance of both valves have been identified for future study.

Theoretical and experimental analysis of the thermoacoustic refrigeration
The thermoacoustic theory is studied in detail and its application to refrigeration is analyzed. This new refrigerator which uses resonant high amplitude sound in inert gases to pump heat will be described. It will be seen that without any moving parts, except the driver (speaker diaphragm), this …

An experimental analysis of the risk-trust confound
The notion of trust has great significance to an economy. Trust is known to be associated with efficient judicial systems, improved government functioning with lower corruption, and better financial outcomes (Johnson and Mislin, 2011). However, many researchers have argued that risk attitudes may …

Design and experimental analysis of legged locomotive robots
… thesis, I present the design and motion-capture analysis of two previously well-studied dynamic-walking machines, the rimless wheel and the compass gait robot. These robots were the basis for my undergraduate research at the Computer Science/Artificial Intelligence Laboratory (CSAIL) at the …

Experimental Analysis of Parameters Influencing the Bone Burring Process
The experimental quantification of the bone removal characteristics associated with bone burring represents a desirable outcome mainly for the selection of optimal parameters. An experimental apparatus was developed that allowed for concurrent measurement of three outputs associated with the bone …

Experimental analysis on the operation of Particle Swarm Optimization
… approximate size of attraction basin. A deeper analysis of the stall condition reveals that it involves clusters of particles that are performing exploitation, and these clusters are separated by individual particles that are performing exploration. This stall pattern can be identified by a …

An experimental analysis of the parameters of facial screening
… In the second study a reversal design-component analysis was used to compare a translucent to an opaque bib. The translucent bib was ineffective in reducing the self-injurious behavior while the opaque bib eliminated self-injurious behavior as long as facial screening was applied consistently.</p>

Experimental Analysis And Evaluation Of Tidy Tree Drawing Algorithms
Tree Drawings have been used extensively in software engineering and many other business and computer applications. The basic structure of a tree allows for the organization and representation of complex information. Many commercial tools allow their users to draw or construct trees to represent a …

Choice with Indexed Alternatives: a Theoretical and Experimental Analysis
In the last forty years, a considerable amount of experimental research in both psychology and economics has reported various violations of the axioms of classical choice theory, but only recently has axiomatic theory started to take into account this empirical evidence. In particular, the recent …
