Attitude determination, along with attitude control, is critical to functioning of every space mission. Here, we investigate the application of a steady-state Kalman Filter for attitude determination using attitude sensors (sun sensor and horizon sensors) and rate integrating gyros. The three-axis steady-state Kalman Filter formulation, adopted from literature, offers obvious computational adva...

Despite the importance of attitude in predicting an individual’s behavior, research on IT adoption has discounted the role of attitude in explaining technology acceptance behavior. Additionally, the attitude construct has often been omitted in research on IT acceptance. In this study, we call attention to the role of attitude in explaining technology acceptance behavior. In developing our resea...

Attitude has been understudied in the information systems (IS) field. Research interest in attitude has gone through ups and downs due to the lack of predictability of attitude for behavioral intention on using ICT. In this paper, we first clarify both conceptual and operational confusions on attitudes that may have caused the inconsistent and inconclusive results. Two different types of attitu...

The Ørsted satellite mission imposes comparatively high requirements on autonomy of the attitude control system. Cost requirements, on the other hand, impose simple hardware and cheap actuators in form of magnetorquer coils. These conflicting requirements are fulfilled through development of novel attitude and control algorithms and wide on-board autonomy. The entire control and attitude determ...

Safety attitude is of vital importance to accident prevention, and the high accident rate in the coal mining industry makes it urgent to undertake research on coal miners’ safety attitude. However, the current literature still lacks a valid and reliable safety attitude measurement scale for coal miners, which stands as a barrier against their safety attitude improvement. In this study, a scale ...

The study was conducted to access the attitude of B.Ed. students towards learning through ICT in relation to their learning style. The objectives of the study was to study the overall favorable attitude of B.Ed. students towards learning through ICT, to study relationship between the attitudes of B.Ed. students towards ICT and their learning style, to study the difference in the attitude of mal...

At large attitudes are built on earlier experience with the attitude object. If earlier experiences are not available, as is the case for unfamiliar attitude objects such as new technologies, no stored evaluations exist. Yet, people are still somehow able to construct attitudes on the spot. Depending on the familiarity of the attitude object, attitudes may find their basis more in affect or cog...

UNLABELLED Past research with the Communication Attitude Test (CAT) has shown it to be a valid and reliable instrument for assessing speech-associated attitude of children who stutter (CWS). However, in Japan, the CAT has not been used extensively to examine the communication attitude of CWS. The purpose of this study was to determine if a Japanese version of the CAT could differentiate between...

In this study, attitude control is proposed for helicopters with actuator dynamics. For the nominal helicopter dynamics, model-based control is firstly presented to keep the desired helicopter attitude. To handle the model uncertainty and the external disturbance, radial basis function neural networks are adopted in the attitude control design. Using neural network approximation and the backste...
