We are investigating new ways to help users learn to use public access interactive tools, in particular for the visual exploration of government statistics. Our work led to a series of interfaces using multi-layered design and a new help method called Integrated Initial Guidance. Multi-layer designs structure an interface so that a simpler interface is available for users to get started and mor...

The purpose of this paper is to design a guidance and control system and evaluate the performance of a sample surface‑to‑surface flying object based on preset guidance with a new prospective. In this study, the main presented idea is usage of unique property of governor differential equations in order to design and develop a controlled system. Thereupon a set of system output variables have bee...

Achievements of the Space Shuttle experience and recent research activities were analyzed and absorbed, and a rapid generation technique of trajectories was focused on for the terminal area of reentry runway-landing flight vehicles. Based on the present processing capability of onboard computers, the trajectory geometry preset planning can be replaced by logic condition based algorithms which c...

This work focuses on the use of mult i-criteria decision-making method AHP for using in educational and vocational guidance. Analytical Hierarchy Process (AHP), proposed by the mathematician Thomas Saaty in 1980, is a method of analysis greatly used in the context of a mult i-criteria analysis; it allows the comparison and the choice between the preset options. To achieve this goal, a vital wor...

We are investigating new ways to help users learn to use public access interactive tools, in particular for the visual exploration of government statistics. Our work led to a series of interfaces using multi-layered design, a new help method called Integrated Initial Guidance, and video demonstrations. Multi-layer designs structure an interface so that a simpler interface is available for users...

We have investigated how birds avoid mid-air collisions during head-on encounters. Trajectories of birds flying towards each other in a tunnel were recorded using high speed video cameras. Analysis and modelling of the data suggest two simple strategies for collision avoidance: (a) each bird veers to its right and (b) each bird changes its altitude relative to the other bird according to a pres...

In recent years, the rapid development of robot technology means more kinds robots appear in life and they are applied different fields society. Service mainly used to provide convenience for human beings. Guide a kind service robot, which can replace manual instruction guidance. However, most existing studies preset guidance trajectory guiding or let user choose next target point position guid...

OBJECTIVE To evaluate three image acquisition presets for four-dimensional cone beam CT (CBCT) to identify an optimal preset for lung tumour image quality while minimizing dose and acquisition time. METHODS Nine patients undergoing radical conventionally fractionated radiotherapy for lung cancer had verification CBCTs acquired using three presets: Preset 1 on Day 1 (11 mGy dose, 240 s acquisi...
