A novel neural architecture aimed to estimate superquadrics parameters form range data is presented. The network topology is designed to model and compute the inside-outside function of an undeformed superquadric in whatever attitude, starting form the (x, y, z) data triples. The network has been trained using backpropagation, and the weights arrangement, after training, represents a robust est...

This paper presents implementation of attitude controller for a small UAV using field programmable gate array (FPGA). Due to the small size constrain a miniature more compact and computationally extensive; autopilot platform is needed for such systems. More over UAV autopilot has to deal with extremely adverse situations in the shortest possible time, while accomplishing its mission. FPGAs in t...

Aiming at the practical situation that the navigation processes of spacecrafts usually rely on several different kinds of tracking equipments which track the spacecraft by turns, a series of new outlier-tolerant fusion algorithms are build to determine the whole flight path as well as attitude parameters. In these new algorithms, the famous gradient descent methods are used to find out the outl...

In this paper, we present an indoor positioning system using foot-mounted low cost Micro-Electro-Mechanical System (MEMS) sensors to derive the position and attitude of the wearer and plot the trajectory on the smartphone in realtime. The pedestrian’s motion information is collected by accelerometers and gyroscopes to achieve Pedestrian DeadReckoning (PDR) which is used to estimate the pedestri...

Wearable computing with Input-Output devices Base on Eye-Based Human Computer Interaction: EBHCI which allows location based web services including navigation, location/attitude/health condition monitoring is proposed. Through implementation of the proposed wearable computing system, all the functionality is confirmed. It is also found that the system does work well. It can be used easily and a...

This paper aims to develop a model for online purchase intention in a B2C environment, integrating cognitive and affective responses based on the theory of reasoned action. Seven hypotheses were developedand tested on a dataset of 532 observations collected via a questionnaire survey. The results of this study indicate that both cognitive and affective judgements are important for online transa...

background and aims. infection control is an important issue in dentistry, and the dentists are primarily responsible for observing the relevant procedures. therefore, the present study evaluated knowledge, attitude, practice, and status of infection control among iranian dentists through systematic review of published results. materials and methods. in this systematic review, the required data...
