The accuracy of attitude determination plays a key role in the improvement of surveying and mapping accuracy for high-resolution remote-sensing satellites, and it is a bottleneck in large-scale satellite topographical mapping. As the on-board energy is constrained and the performance of an attitude-measurement device is limited, the attitude acquired is discretely sampled with a settled time in...

This paper presents the design and performance evaluation of a novel integrated attitude filter with application to space navigation. The design is based directly on the sensor measurements as opposed to traditional solutions that resort to rotation parameterizations. The information provided by a low-cost star tracker is merged with the measurements of a triaxial rate gyro to provide accurate ...

Purpose: To compare the effectiveness of a one-time sexual assault prevention theatre performance against a similar content video performance and a non-intervention control group. Methods: Using the College Date Rape Attitudes and Behaviors Survey, four-hundred ninety-seven students provided matched pairs data for analysis. Results: At a three-month follow-up when compared to students in other ...

IN THE study of the APRL-Sierra No. 1 right hand, which preceded that of the left, the results of comparative performance testing indicated that there was little difference between the hand and the hook on the various test activities. Statements of children participating in the study—and of their parents—indicated a relatively high level of performance with the experimental hand, but advantages...

Experimental studies are required to understand the contribution of audio and visual modalities during affective communication. This paper presents a perception study of the audio-visual expression of six French attitudes. The relative importance of each modality in the decoding of these expressions is analysed, as a first step toward a deeper comprehension of their influence on social affects ...
