Cluster Life Cycles: Types and Driving Factors

Cluster Life Cycles - Dimensions and Rationales of Cluster Development

We present a model that explains how a cluster moves through a life cycle and why this movement differs from the industry life cycle. The model is based on three key processes: the changing heterogeneity in the cluster describes the movement of the cluster through the life cycle; the geographical absorptive capacity enables clustered companies to take advantage of a larger diversity of knowledg...

Driving Cycles Project Final Report

Wheelchair batteries: driving cycles and testing.

The battery performance of electric wheelchairs was measured under indoor and outdoor conditions, and simulated driving cycles for these two environments were derived from these tests. Driving cycles were used to bench-test deep discharge wet cell and gel cell lead-acid batteries, nickel-cadmium batteries, and experimental nickel-zinc batteries. Results of this study support the conclusion that...

Psychotropic drugs and driving: prevalence and types

BACKGROUND Some psychotropic medications (e.g., benzodiazepines, sedative antidepressants, etc.) may impair cognitive and psychomotor functions and, therefore, endanger traffic safety (Ravera, Br J Clin Pharmacol, 72(3):505-513, 2011). They affect detection, registration, and information processing, problem solving, and decision-making processes, and they also affect emotional and social aspect...
