The ability of Gaussian noise to induce ordered states in dynamical systems is here presented in an overview of the main stochastic mechanisms able to generate spatial patterns. These mechanisms involve: (i) a deterministic local dynamics term, accounting for the local rate of variation of the field variable, (ii) a noise component (additive or multiplicative) accounting for the unavoidable env...
Localized ecological interactions can generate striking large-scale spatial patterns in ecosystems through spatial self-organization. Possible mechanisms include oscillating consumer-resource interactions, localized disturbance-recovery processes and scale-dependent feedback. Despite abundant theoretical literature, studies revealing spatial self-organization in real ecosystems are limited. Rec...
Zusammenfassung Mit der Urban Challenge hat die DARPA Ende 2007 ihr erklärtes Ziel erreicht, nachzuweisen, dass autonomes Fahren prinzipiell möglich ist. In diesem Ar-tikel wird skizziert, welcher Stand tatsächlich erreicht wurde und welche Herausforderungen nun bearbeitet werden wollen. Summary Late in 2007, DARPA has conducted the Urban Challenge and achieved its declared goal, that autonomou...
This paper describes a system for detecting and estimating the properties of multiple travel lanes in an urban road network from calibrated video imagery and laser range data acquired by a moving vehicle. The system operates in several stages on multiple processors, fusing detected road markings, obstacles, and curbs into a stable non-parametric estimate of nearby travel lanes. The system incor...
This article presents the architecture of Junior, a robotic vehicle capable of navigating urban environments autonomously. In doing so, the vehicle is able to select its own routes, perceive and interact with other traffic, and execute various urban driving skills including lane changes, U-turns, parking, and merging into moving traffic. The vehicle successfully finished and won second place in...
during grain development, appropriate water status of soil has key importance for starch accumulation in grains and hormone changes. for this, the study carried out on two iranian wheat cultivars pishtaz and karaj 3 in a factorial experiment based on randomized complete block design with three replications under irrigated and drought in a field experiment at research farm of agriculture college...
