Beagle2 is the UK-led lander element on ESA’s Mars Express mission, which will reach Mars in late December 2003. After separation from the Mars Express orbiter 6 days before the atmospheric entry, Beagle2 will descend to the Martian surface by means of ablative heat shields and parachutes. The impact will be cushioned by a set of airbags. The selected landing site at 11.6 deg N / 90.75 deg E (I...

As the main means of monitoring and early warning of geological disaster, the slope stability analysis is an important part of the geological disaster prevention project. GIS plays an important role in the evaluation of slope stability due to its powerful functions for data processing and spatial analysis. This article discusses the key technology of GIS applied in the slope bolt support design...

T he nation’s best performing healthcare systems continue to improve efficiency and have the bottom lines to show it, judging from results of a yearly survey of integrated health networks. Improved occupancy, well-integrated information systems and strong margins marked the results for the 11th annual ranking of health system efficiency and performance by Yardley, Pa.based Verispan, a healthcar...

The objective of the study was to determine the effect of landing surface on plantar kinetics during a half-squat landing. Twenty male elite paratroopers with formal parachute landing training and over 2 years of parachute jumping experience were recruited. The subjects wore parachuting boots in which pressure sensing insoles were placed. Each subject was instructed to jump off a platform with ...

Multi-version software systems achieve fault tolerance through somare redundancy and diversity. In order to investigate this approach, this joint UCLAIHoneywell research project investigated multi-version sojhvare systems, employing six different programming languages to create six versions of s o p a r e for an automatic landing program. The rationale, preparation. execution, and evaluation of...

Objectives: Children aged 10 to 12 years often show dangerous maneuvers during landing, which include increased knee valgus, placing them at higher risk of anterior cruciate ligament (ACL) injuries. The study aimed to investigate the relation of the trunk and hip kinematics with the peak knee abduction angle during single-leg landing among preadolescent female soccer players. Methods: Thirty-s...

We hypothesize that application of an unopposed quadriceps force coupled with an impulsive ground reaction force may induce anterior cruciate ligament (ACL) injury. This situation is similar to landing from a jump if only the quadriceps muscle is active; an unlikely but presumably dangerous circumstance. The purpose of this study was to test our hypothesis using in vitro simulation of jump land...

It is natural to rely on experiences from the aviation industry when developing safety-critical systems for automotive applications. In the aviation industry for several decades programmable systems have been used for flight control, aircraft engine control, landing gear control etc.. The safety and reliability requirements of these systems are comparable with steer-by-wire or brake-by-wire sys...
