The formation control of multiple vehicles using a perceptive frame is studied in this paper. The method is applied to multiple mobile robots. The controller design and lab experiments are shown in the paper. Some useful strategies of coordination are implemented in a perceptive frame by reference projections. The feature of the coordination is illustrated by experiments of three mobile robots.

Conventional particle swarm optimisation relies on exchanging information through social interaction among individuals. However for real-world problems involving control of physical agents (i.e., robot control), such detailed social interaction is not always possible. In this study, we propose the Perceptive Particle Swarm Optimisation algorithm, in which both social interaction and environment...

This paper discusses a perception-based theory for a multi-variate stopping problem with a monotone rule by Yasuda et al. (1982). The problem is developed by using the perceptive analysis of the previous work(Kurano et al. (2004)). We will show a recursive equation which determines the perceptive value of its equilibrium point for the model.

The development and continuous improvement of campus networks brings new changes to the campus and college life, more and more students are turning to micro-blog to express their views and opinions, and through the micro blogging to achieve fast and efficient sharing and exchange of information and resources. In the micro blog era, the power of micro blogging can not only impact college student...

terrorism is a violent action with special features; terrorists are different than other criminals too and it is not possible to judge them as crazy criminals or a person with deviant character or someone who is affected by the inappropriate financial circumstances. terrorists are individuals with planed acts faced to the specific aims which are prompted by the ideological motives. in this thes...

Previous research has shown the existence of strong relationships between affective polarization and culture wars, but it is unknown to what extent this emotional division is, in fact, a ‘false polarization’ generated from second-order beliefs those identity issues that categorize define group membership. Using data ‘First National Survey Political Polarization’ Spain, an operationalization con...

Recent research has shown dramatic benefits to incorporating social media in public facing websites. Using a perspective based on the duality of goals, we argue that social media, with emphasis on facilitating visitors’ unconstrained exchanges, may undermine the communicative purpose of an organization’s website and may not be desirable in some cases. We tested these ideas by examining the soci...

Psychophysical length and width spatial interactions associated with a line target were measured in normal observers dichoptically and in observers with naturally acquired amblyopia to investigate the neural locus of end-stopped perceptive fields. Results show (1) interocular transfer of psychophysical end-stopping, flank-inhibition, and length and width summation; and (2) severe, but significa...
