Automated Road Milling Cutter for Repair of the Road Surfaces with Variable Trackage

Study of the effective cutter radius for end milling of free-form surfaces using a torus milling cutter

Optimizing Road Milling and Resurfacing Actions

A condition-based maintenance optimization approach is developed for the road-cracking problem in order to derive optimal maintenance policies that minimize a total discounted maintenance cost. The approach is based on a Markov decision process that takes into account multiple actions with varying effects on future road performance. Maintaining the road consists of adding a new asphalt layer; h...

Computing Cutter Engagement Values in Milling Tessellated Free-Form Surfaces

High speed milling (HSM) has great potential use in die/mold cutting, but traditional machining plans do exploit HSM capabilities effectively. An important consideration for in HSM is to limit cutting force variations, and one way to do so is to reduce Cutter-Workpiece engagement (CWE) variations. CWE is measured as the area of the tool instantaneously engaged with the part. Estimating CWE as a...

Repair road map

A report on page 195 by BekkerJensen et al. maps out the damage-induced rearrangement of proteins involved in repairing doublestranded DNA breaks (DSBs). The map, the authors hope, will help scientists assign functions to future putative damageresponsive proteins. Treatments such as ionizing radiation (and chemotherapy) that induce DSBs lead to the accumulation of nuclear foci containing repair...

Coding of Road Information for Automated Highways

Communication of information from the roadway infrastructure to vehicles is expected to enhance Automated Highway Systems (AHS) by supporting subsystem functions like vehicle motion control, multiple vehicle coordination, and vehicle navigation. A suitable communication channel is information coding in the lateral reference used for automatic steering and lane keeping control, e.g. in the magne...
