On the drive dynamics of a 4WS-car
In the article study of drive dynamics of a 4WS-car (Four-Wheel Steering) based on the one-track model is resumed. Attention was focused on three single problems. At solving equations both analytical and numerical techniques were applicated. To effect calculations and plot outputs the programming language Matlab was used.

Robust navigation control of a 4WD/4WS agricultural robotic vehicle
Abstract This paper reports the development of a robust controller based on backstepping sliding mode control (SMC) for a four-wheel-steering (4WS) and four-wheel-drive (4WD) agricultural robotic vehicle. Two RTK-GPS receivers were installed on the vehicle to provide feedback of the robot’s location and orientation.

Computer modeling in nonlinear optics: 4W-mixing theory [PDF]
A fully-quantized nonperturbative coherent four-wave (4W) mixing theory and a three-dimensional computer program to solve the model are presented here. A detailed algorithm for the solution, program extension for extra resonances, and plotting techniques are also given.

Who Drowns? Encoding the Second Component of the 4W Model
The aim of the current study was to identify the casualty characteristics that contribute to drowning according to the 4W model (Avramidis, Butterly, & Llewellyn, 2007, 2009). Qualitative content analysis was used to analyze drowning incident videos (n = 41) and semistructured interviews of those involved in drowning incidents (n = 34). Results confirm

The autodriver algorithm is an intelligent method to eliminate the need of steering by a driver on a well-defined road. The proposed method performs best on a four-wheel steering (4WS) vehicle, though it is also applicable to two-wheel-steering (TWS ...
