Rendezvous radar for the orbital maneuvering vehicle

This paper describes the development of the Rendezvous Radar Set (RRS) for the Orbital Maneuvering Vehicle (OMV) for the National Aeronautics and Space Administration (NASA). The RRS was to be used to locate, and then provide vectoring information to, target satellites (or Shuttle or Space Station) to aid the OMV in making a minimum-fuel-consumption approach and rendezvous. The RRS design is that of an X-Band, all solid-state, monopulse tracking, frequency hopping, pulse-Doppler radar system. The development of the radar was terminated when the OMV prime contract to TRW was terminated by NASA. At the time of the termination, the development was in the circuit design stage. The system design was virtually completed, the PDR had been held. The RRS design was based on Motorola's experiences, both in the design and production of radar systems for the US Army and in the design and production of hi-rel communications systems for NASA space programs. Experience in these fields was combined with the latest digital signal processor and micro-processor technology to design a light-weight, low-power, spaceborne radar. The antenna and antenna positioner (gimbals) technology developed for the RRS is now being used in the satellite-to-satellite communication link design for Motorola's Iridium telecommunications system

The relationships between porcine longissmus dorsi histological traits and carcass and performance characteristics

Twenty-six hogs were raised four to a pen until the average weight per pen was 100 kg. Immediately after slaughter the carcass weight, carcass length and back fat thickness were measured. Following a 14 to 16 hour chill, the weights of the trimmed hams and loins were recorded and converted into percentages. The loin eye at the 10th rib was scored for color and marbling and a one inch chop removed for histological examination. Cross sections (16 microns) were stained for ATPase activity and the muscle fiber types differentiated. Their areas and numbers were recorded and the mean areas and percentages of each fiber type were calcu-lated. The fat cells were stained with Oil-Red-0 and their mean areas calculated. Six of these cross sections for each sample were given a histologically determined marbling score. Simple correlation coefficients were calculated. These showed a relationship between histologically determined marbling and loin eye area (-.49), back fat thickness (0.47) and marbling (0.61). The mean fat cell area was signifi-cantly correlated with loin eye area (-.60), back fat thick-ness (0.55) and marbling (0.52). All the barrows were Durocs and all of the gilts were crossbreeds, therefore any variation between the two groups could not be designated as a result of either sex or breed. The analysis of variance between the Duroc barrows and crossbreed gilts indicated that the mean fat cell area, back fat thickness and marbling score were significantly (P \u3c .01) larger for the Duroc barrows. The crossbreed gilts had significantly (P \u3c ,01) longer hot carcass lengths, higher percent ham and loin and larger loin eye area

State-of-The-Art Technology Applications

This document provides information on descriptions of state-of-the-art technology using schools across the country. It is a resource that can be used by teachers, school administrators, and researchers who are investigating the varying applications of technology in the classroom. It should be helpful in: 1) learning how other schools have implemented similar technology and integrated in within specific curricula, 2) planning, purchasing, adopting, or implementing technology in a classroom or entire school, and 3) it serves as a valuable resource to identify such schools already engaged in exceptional educational technology usage

Efficient optimisation of structures using tabu search

This paper presents a novel approach to the optimisation of structures using a Tabu search (TS) method. TS is a metaheuristic which is used to guide local search methods towards a globally optimal solution by using flexible memory cycles of differing time spans. Results are presented for the well established ten bar truss problem and compared to results published in the literature. In the first example a truss is optimised to minimise mass and the results compared to results obtained using an alternative TS implementation. In the second example, the problem has multiple objectives that are compounded into a single objective function value using game theory. In general the results demonstrate that the TS method is capable of solving structural optimisation problems at least as efficiently as other numerical optimisation approaches

Effect of Brief Biofeedback via a Smartphone App on Stress Recovery: Randomized Experimental Study.

BACKGROUND:Smartphones are often vilified for negatively influencing well-being and contributing to stress. However, these devices may, in fact, be useful in times of stress and, in particular, aid in stress recovery. Mobile apps that deliver evidence-based techniques for stress reduction, such as heart rate variability biofeedback (HRVB) training, hold promise as convenient, accessible, and effective stress-reducing tools. Numerous mobile health apps that may potentially aid in stress recovery are available, but very few have demonstrated that they can influence health-related physiological stress parameters (eg, salivary biomarkers of stress). The ability to recover swiftly from stress and reduce physiological arousal is particularly important for long-term health, and thus, it is imperative that evidence is provided to demonstrate the effectiveness of stress-reducing mobile health apps in this context. OBJECTIVE:The purpose of this research was to investigate the physiological and psychological effects of using a smartphone app for HRVB training following a stressful experience. The efficacy of the gamified Breather component of the Happify mobile health app was examined in an experimental setting. METHODS:In this study, participants (N=140) underwent a laboratory stressor and were randomly assigned to recover in one of three ways: with no phone present, with a phone present, with the HRBV game. Those in the no phone condition had no access to their phone. Those in the phone present condition had their phone but did not use it. Those in the HRVB game condition used the serious game Breather on the Happify app. Stress recovery was assessed via repeated measures of salivary alpha amylase, cortisol, and self-reported acute stress (on a 1-100 scale). RESULTS:Participants in the HRVB game condition had significantly lower levels of salivary alpha amylase during recovery than participants in the other conditions (F2,133=3.78, P=.03). There were no significant differences among the conditions during recovery for salivary cortisol levels or self-reported stress. CONCLUSIONS:These results show that engaging in a brief HRVB training session on a smartphone reduces levels of salivary alpha amylase following a stressful experience, providing preliminary evidence for the effectiveness of Breather in improving physiological stress recovery. Given the known ties between stress recovery and future well-being, this study provides a possible mechanism by which gamified biofeedback apps may lead to better health
