This paper presents some results of a study, which aimed at modelling pavement evolution by different methods. In a first part, a database was constituted with data collected on French roads in the last decades. The database contains skid resistance values (Sideway Force Coefficient measured by SCRIM/Sideway force Coefficient Routine Investigation Machine), macrotexture values (Mean Profile Dep...

A parafoil controlled by parafoil brake de ection offers a lightweight and space-efŽ cient control mechanism for autonomous placement of air-dropped payloads to speciŽ ed ground coordinates. The work reported here investigates control issues for a parafoil and payload system with left and right parafoil brakes used as the control mechanism.It is shown thatparafoilandpayloadsystems can exhibit ...

Negative slope coefficient has been recently introduced and empirically proven a suitable hardness indicator for some well known genetic programming benchmarks, such as the even parity problem, the binomial-3 and the artificial ant on the Santa Fe trail. Nevertheless, the original definition of this measure contains several limitations. This paper points out some of those limitations, presents ...

Because pigs frequently lose their footing and slip, it is important to understand slipping and its relation to different floor surfaces. An experiment was conducted to evaluate the gait and footing of young pigs walking on concrete floor surfaces having known friction characteristics and to determine critical skid resistance values in terms of the fitness of a concrete surface for flooring in ...

This paper addresses issues in the design of wheel grousers for planetary rovers. It has been shown in prior and related work that grousers on wheel rims can improve traveling performance of rovers on loose soils. However, the main focus of these studies, so far, has been limited to straight grousers and to straight line motion of the wheels. This work extends such studies to include chevron-sh...

MOTIVATION TRAIL has been widely studied for the ability to kill cancer cells selectively, but its clinical usefulness has been hindered by the development of resistance. Multiple compounds have been identified that sensitize cancer cells to TRAIL-induced apoptosis. The drug LY303511 (LY30), combined with TRAIL, caused synergistic (greater than additive) killing of multiple cancer cell lines. W...

This paper develops and experimentally demonstrates a robust automatic parallel parking algorithm for parking in tight spaces. Novel fuzzy logic controllers are designed for each step of the maneuvering process. The controllers are first demonstrated by simulation using the kinematic model of a skid steering autonomous ground vehicle (AGV). They are then demonstrated experimentally on a skid st...

Low skid resistance of road marking paint is one of the major issues in the safety of vehicle drivers, cyclists, and pedestrians when traveling on the city streets. Among the variety of marking paint, two-component paint is widely used at intersections and roundabouts. Therefore, the paint used should have adequate skid resistance. The object of this study was to evaluat...
