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...

The paper explores the factors that affect employees’ attitude and behaviour towards knowledge sharing in Saudi Arabian organisations. A mixed methods approach was used to gather data through a survey and semi-structured interviews. Trust was found to have a negative relationship with knowledge sharing attitude while collaborative climate, management support, openness, and rewards were found to...

Existing position controllers for VTOL UAVs require measurements of the system attitude (orientation) for feedback. However, in practice the orientation cannot be measured directly; it is rather obtained through the use of an attitude observer relying on a set of inertial vector measurements. In this paper a new control strategy is proposed for VTOL-UAVs which avoids the direct measurement of t...

Attitude theory has long proposed a mechanism through which antecedents of message elaboration produce attitude strength consequences. However, little direct evidence exists for the intervening process. The proposed thoughtfulness heuristic holds that perceiving that more thought has taken place leads to greater attitude certainty. Two roles were established for this heuristic: first as a media...

This paper investigates previously unrecognized aspects of the interpretation of clausal arguments of propositional attitude predicates. It provides an account of them based on a newly identified modal operator in the lexical meaning of propositional attitude predicates, which applies to the context change in an attributed information state effected by the argument clause of the attitude predic...

This paper proposes a dynamic analytical initialization method for spacecraft attitude estimators. In the proposed method, the desired attitude matrix is decomposed into two parts: one is the constant attitude matrix at the very start and the other encodes the attitude changes of the body frame from its initial state. The latter one can be calculated recursively using the gyroscope outputs and ...

This paper investigates the syntactic and semantic properties of counterfactual attitude verbs in Taiwanese Southern Min, showing the differences between this type of attitude verbs and those discussed by Anand and Hacquard (2013). I propose that the semantics of counterfactual attitude verbs is composed of two components, a doxastic assertion and a counterfactual felicity condition, the former...

Fazio has shown that repeated attitude expressions increase the accessibility of the attitude. Increases in accessibility in turn lead to greater attitude-behavior consistency. The present work examines the effects of repeated expressions on attitude extremity. In the 1st study, it is shown that repeated expressions increase extremity when the expressions involve only judgments of attitude vale...

Recent theoretical and methodological innovations suggest a distinction between implicit and explicit evaluations. We applied Campbell and Fiske's (1959) classic multitrait-multimethod design precepts to test the construct validity of implicit attitudes as measured by the Implicit Association Test (IAT). Participants (N = 287) were measured on both self-report and IAT for up to seven attitude d...

The enhanced attitude control system experiment is a technology demonstration experiment on the NASA’s small spacecraft technology initiative program’s Lewis spacecraft to evaluate advanced attitude control strategies. The purpose of the enhanced attitude control system experiment is to evaluate the feasibility of designing and implementing robust multi-input/multi-output attitude control strat...
