Integrating testing techniques through process programming
Integration of multiple testing techniques is required to demonstrate high quality of software. Technique integration has three basic goals: incremental testing capabilities, extensive error detection, and cost-effective application. We are experimenting with the use of process programming as a mechanism of integrating testing techniques. Having set out to integrate DATA FLOW testing and RELAY, we proposed synergistic use of these techniques to achieve all three goals. We developed a testing process program much as we would develop a software product from requirements through design to implementation and evaluation. We found process programming to be effective for explicitly integrating the techniques and achieving the desired synergism. Used in this way, process programming also mitigates many of the other problems that plague testing in the software development process
Caging Mechanism for a drag-free satellite position sensor
A disturbance compensation system for satellites based on the drag-free concept was mechanized and flown, using a spherical proof mass and a cam-guided caging mechanism. The caging mechanism controls the location of the proof mass for testing and constrains it during launch. Design requirements, design details, and hardware are described
Elastic suspension of a wind tunnel test section
Experimental verification of the theory describing arbitrary motions of an airfoil is reported. The experimental apparatus is described. A mechanism was designed to provide two separate degrees of freedom without friction or backlash to mask the small but important aerodynamic effects of interest
Study to develop gradiometer techniques
The primary goal of the current gravity gradiometer research at Stanford has been to establish the feasibility of using a gravity gradiometer with 1 E accuracy, as the primary sensor in various applications. The two applications considered here in detail are geodesy missions and inertial navigation systems. Preliminary sections on gravity models and gravity gradiometer bias estimation are also included
Develop minimum thrustor control laws and select orbits for a geodesy drag-free satellite
The original motivation for studying control laws for pulse plasma systems was based on the improved life characteristics possible with pulse plasma jets. These pulse plasma units are relatively massive compared with cold gas thrustors. As a result, therefore, significant mass savings can be achieved by minimizing the the number of thrustors. The control laws, therefore, were developed for thrust available from two thrustors only. In a spinning satellite, these thrustors are sufficient to completely control the vehicle as long as the spin rate is sufficiently high for a given level of external disturbance. The thrustors are canted so that a component of each is along the plus and minus spin axis. The other component of each thrustor acts in the radial direction. It is sufficient to analyze the behavior in the plane of spin assuming a single thrustor
On the applicability of integrated circuit technology to general aviation orientation estimation
The criteria of the significant value of the panel instruments used in general aviation were examined and kinematic equations were added for comparison. An instrument survey was performed to establish the present state of the art in linear and angular accelerometers, pressure transducers, and magnetometers. A very preliminary evaluation was done of the computers available for data evaluation and estimator mechanization. The mathematical model of a light twin aircraft employed in the evaluation was documented, the results of the sensor survey and the results of the design studies were presented
Publishing data evidence to support educational technology claims [Editorial]
As is evident by this issue, JTATE publishes works that include rich data evidence, regardless of the method used in the research design. Detailed and careful research analyses, as well as purposeful design and construction of the write-up are critical to building a strong foundation of educational technology literature. Researchers in educational technology and technology and teacher education more specifically, who decide to follow a platinum standard for research publication, are strengthening and broadening the credibility of a relatively young field. The JTATE editors promote this line of thinking, encouraging editorial board members, reviewers, and authors to assist with this important goal
Laurence Dunn, March 4, 1825-January 2, 1895
An Irish immigrant who came to Savannah in about 1851, Laurence Dunn quickly established himself in financial and community affairs. His business interests included real estate, a grocery store and saloon, and some involvement with the shipping industry. Mr. Dunn married Catherine Mitchell in 1854 and together they had five or six children, three of whom lived to maturity. He enlisted to serve in the Con federate Army in 1862. Catherine M. Dunn died in late 1889 and Mr. Dunn survived her by five years, dying in January, 1895. The Dunn descendants were and are active members of the Savannah community in the fields of education, medicine, commerce and law.https://digitalcommons.georgiasouthern.edu/sav-bios-lane/1052/thumbnail.jp

CRIMES AND OFFENSES Controlled Substances: Provide Procedures for the Seizure and Disposition of Forfeited Property; Provide for Liens on Property Subject to Forfeiture; Provide for Distribution of Forfeited Property and the Proceeds from Such Property
The Act declares that certain items are contraband, and that no property rights exist as to those items. The Act provides for the seizure of property subject to forfeiture and for the filing of a lien for forfeiture upon the initiation of any civil or criminal proceeding under this article, as well as upon seizure. The Act provides procedures for forfeiture and the conditions required for the filing of a temporary restraining order against property subject to forfeiture. The Act provides for the evidence to be admissible at hearings and determinations made subject to forfeiture, as well as for inferences and rebuttable presumptions. The Act provides that forfeited property vests in the State at the time of conduct giving rise to the forfeiture. The Act provides for the disposition, sale, or destruction of property forfeited, and provides for the distribution and use of property and proceeds of forfeited property
