The goal of this research is to develop algorithms using low-resolution images to perceive and understand a typical indoor environment and thereby enable a mobile robot to autonomously navigate such an environment. We present techniques for three problems: autonomous exploration, corridor classification, and minimalistic geometric representation of an indoor environment for navigation. First, w...

Path finding has focused primarily on collision free paths that are smooth and short. However, in todays computer games, it is often desired to stay out of sight of enemies and, as a result, close to obstacles. In this paper we propose a method that uses an existing roadmap and produces a set of corridor polygons from which a path is generated. Weights calculated from tactical data can be speci...

This paper describes the design of an optimal-control-based active safety framework that performs trajectory planning, threat assessment, and semiautonomous control of passenger vehicles in hazard avoidance scenarios. The vehicle navigation problem is formulated as a constrained optimal control problem with constraints bounding a navigable region of the road surface. A model predictive controll...

A deterministic model based on ray tracing and dealing with periodic roughness is developed, for an indoor radio propagation channel and experimentally validated at a frequency of 10GHz. Two different scenarios are studied, namely a smooth corridor and a corridor having artificial periodic roughness. The periodic roughness consists of a set of conductive semi-cylinders attached to the corridor ...

The corridor between Oslo and Berlin is by the politicians of the regional authorities in the Scandinavian part of the corridor seen a region with unique qualities and a large innovation and growth potential. In order to explore and develop this potential an Interreg project has been launched. Even though development of transport infrastructure is seen as pivotal in this process, there is a com...

Supply chains are the backbone of trade and commerce. Their logistics use different transport corridors on regular basis for operation al purpose. The international supply chain transport corridors include different infrastructure elements (e.g. weighbridge, package handling equipments, border clearance authorities, and so on). Th is paper presents th e use of multi-agent systems (MAS) to model...

At present, there is obvious regional segmentation in the protection of intangible cultural heritage (ICH) Yangtze River Economic Belt. ArcGIS spatial analysis method and minimum cumulative resistance (MCR) models are used to investigate distribution characteristics ICH suitability corridor construction this region. On basis, strategies for proposed. (1) The results show that density Belt have ...

The purpose of this study is to characterize the indoor channel for IEEE 802.16 (WiMAX) at 3.3 to 3.6 GHz frequency. This work presents a channel model based on measurements conducted in commonly found scenarios in buildings. These scenarios include closed corridor, wide corridor and semi open corridor. Path loss equations are determined using log-distance path loss model and a Rayleigh multipa...

The influence of spatially distinct host subpopulations on helminth community structure and pattern was examined in a migratory avian host species. Forty helminth species represented by 24,082 individuals were collected from 184 blue-winged teal (Anas discors; BWT) from 2 primary migratory corridors in Florida (eastern migratory corridor; EMC) and Louisiana and Texas (western migratory corridor...

Leeches are fascinating creatures: they have simple modular nervous circuitry yet exhibit a rich spectrum of behavioural modes. Leeches could be ideal blue-prints for designing flexible soft robots which are modular, multi-functional, fault-tolerant, easy to control, capable for navigating using optical, mechanical and chemical sensorial inputs, have autonomous inter-segmental coordination and ...
