In daily life, our behavior is guided by various visual stimuli such as the information on direction signs. However, our environmentally-based perceptual capacity is often challenged in crowded circumstances, or more so, in emergency evacuation circumstances. In those situations, we often fail to pay attention to important signs. In order to achieve more effective direction guidance, we conside...

We introduce the concept of Audio Bubbles virtual spheres filled with audio that are geocentered on physical landmarks, providing navigational homing information for a user to more easily locate the landmark. We argue that the way in which tourists navigate is not well supported by traditional visual maps, and that Audio Bubbles better support the serendipitous discovery and homing behaviours e...

Recent studies of the semaphorin family of axon guidance signals and their receptors have revealed a surprising versatility in the ways that they can be used solve problems in neural development, and provided new opportunities for understanding how guidance information is interpreted beneath the cell surface.

Differential geometric guidance command (DGGC) is widely acknowledged as a better method of endoatmospheric interception than three-dimensional (3D) pure proportional navigation (PPN). DGGC can be regarded as an intelligent method due to its sophisticated sense of Lyapunov. However, traditional DGGC cannot guarantee line of sight (LOS) finite time convergence (FTC) to zero against maneuvering t...

A new guidance scheme for the problem of Low-thrust transfer between inclined orbits is developed within the framework of optimal control theory. The objective of the guidance scheme is to provide the appropriate thrust steering program that will transfer the vehicle from an inclined low earth orbits to the high earth orbits. The presented guidance scheme is determined using Pontryagin’s princi...

this aper is concerned with the issue of academic guidance of high school students in iran, the present processes of academic guidance in new system of high school rely on criteria and indices that, the usefulness of some of which seriously in doubt. in this artic le. awhile the criteria and indices of current practices are criticized. an attempt has also been made to predict academic achieveme...

In this paper we consider the problem of air to ground missile guidance system using fuzzy controller which uses Proportional Navigation and Pure Pursuit methods. The fuzzy controller’s rules are defined using Tabu Search (TS). The missile model is assumed as three degree of freedom (3DOF) (assuming the analysis in the vertical plane only). This paper presents numerical results for applying the...
