We are studying a hydraulic system design and vehicle dynamic modeling for a development of tire roller system, because those are very important in analysis of tire roller. Generally, tire roller is one of the useful machines in a road construction field and it technically applied for many other construction fields. Also, we conceptualize of new hydraulic and traction system, and define about t...

This paper gives an overview of the current industry based projects in the field of vehicle modeling and simulation in the Duisburg Mechatronics Laboratory. It shows the wide range of research fields covered in Duisburg, including vehicle systems, vehicle dynamics, occupant safety, adaptive cruise control, power steering, hardware in the loop, fault tolerant real time systems and tolerance anal...

Radio frequencies in bands around 28 GHz are being discussed as candidates for mobile communications of the fifth generation (5G). Beam steering will be a key feature in the context of 5G. It will be a major challenge to test the beam steering capabilities of base stations and user equipment in every phase from research and development through production. Conducted measurements will be mainly r...

An international track wheelchair (ITWC) with a center of gravity directional controller (COGDC) is described in this paper. The rules for international track competition disallow devices designed solely for steering. Equipment has been disqualified for having steering handles, crown compensators, and other lever systems. However, the rules do allow tie-rod linkage and the use of springs for da...

OBJECTIVE To find an association between cognitive-perceptual problems of older drivers and unsafe driving performance during simulated automobile driving in a virtual environment. DESIGN Cross-sectional study. SETTING A driver evaluation clinic in a rehabilitation hospital. PARTICIPANTS Fifty-five drivers aged 65 years or older and 48 drivers in their late twenties to early forties. ME...
