An approach to vision-based vehicle localization by viewing corridors as a combination of right parallelepipeds is proposed. The objective is to derive the orientation and lateral position of a vehicle in a right parallelepiped corridor. These two kinds of information are all that is needed for vehicles to navigate safely in a right parallelepiped corridor. This approach offers low hardware cos...

soil salinity is one of the problems threatening agricultural lands. parts of this phenomenon are related to geologic formations and saltpans, while some major factors are resulted from irrelevant agricultural activities, issue of irrigation, and improper cultivation systems which lead to increase in soil salinity. to avoid such consequences that would end up with ecosystem degradation, suitabl...

The characteristics of well-developed downslope winds observed by tethered balloon soundings at multiple locations over a low-angle slope in the Salt Lake Valley are studied using the Regional Atmospheric Modeling System (RAMS). The model successfully simulated the key properties of the observed wind and temperature structure and evolution and provided insight into the forcing mechanisms. The r...

Abstract This paper investigates the surface-layer processes associated with morning transition from nighttime downslope winds to daytime upslope over a semi-isolated massif. It provides an insight into characteristics of and its connection controlling erosion temperature inversion at foot slope. First, criterion for identification days prone development purely thermally driven slope is propose...

INTRODUCTION As shown by McGeer (1990), the passive dynamics of the legs are sufficient to walk down a gentle slope with no external control, and no external energy input save from gravity. Here we consider different models based on passive dynamics, including actively powered models that still make use of passive dynamic principles. We consider the stability of these models, and the implicatio...
