within the country , there is evidence of the prevalence of alcohol consumption among young people and students. the major purpose of the present study was to investigate social science faculty of tehran university students’ attitude toward alcohol consumption and to explain this attitude from rational choice theory perspective. the method of this research was survey and the data collection ins...

We begin this article with the assumption that attitudes are best understood as structures in longterm memory, and we look at the implications of this view for the response process in attitude surveys. More specifically, we assert that an answer to an attitude question is the product of a fourstage process. Respondents first interpret the attitude question, determining what attitude the questio...

In this paper, an optimal batch estimator and filter based on the Minimum Model Error (MME) approach is developed for three-axis stabilized spacecraft. Three different MME algorithms are developed. The first algorithm estimates the attitude of a spacecraft using rate measurements. The second algorithm estimates the attitude without using rate measurements. The absence of rate data may be a resu...

BACKGROUND Knowing and, if necessary, altering competitive athletes' real attitudes towards the use of banned performance-enhancing substances is an important goal of worldwide doping prevention efforts. However athletes will not always be willing to reporting their real opinions. Reaction time-based attitude tests help conceal the ultimate goal of measurement from the participant and impede st...

Ballistic correction rocket is a kind of smart ammunition which can attach aims exactly. Based on domestic and foreign literature, the technology of flight attitude measurement technology was summarized. The process of the research includes independently inertial measurement unit and inertial navigation system. The previous stage is the measurement technology only depend on a navigation equipme...

A formation optical range and attitude sensor is being developed that uses a laser beam source and a modulated retro-reflector (MRR) target to measure distances between a few meters and a few kilometers with sub-millimeter resolution. Data extracted from multiple MRR targets on a single spacecraft will also provide arcminute-accuracy attitude information with over a ±10-deg field of view. Infor...

The focus of this study is on the attitude estimation of the four-rotor helicopter known as quadrotor. The choice of the algorithm is a complementary filter based on quaternions. For the four-rotor helicopter system has nonlinear, strong coupling, multi-variable features, it is difficult to obtain the accurate attitude values, and in order to solve this problem a quaternion-based complementary ...

This article introduces the Causal Attitude Network (CAN) model, which conceptualizes attitudes as networks consisting of evaluative reactions and interactions between these reactions. Relevant evaluative reactions include beliefs, feelings, and behaviors toward the attitude object. Interactions between these reactions arise through direct causal influences (e.g., the belief that snakes are dan...
