Average Speed Bumps: Four Perspectives on Averaging Speeds

Average Speed Bumps: Four Perspectives on Averaging Speeds

highway, where each car travels at a constant speed. Assume that the distribution of the speeds is the same throughout the length of the highway. You adjust your speed so that during a given time unit you overtake the same number of cars as the number of cars that overtake you. Does this mean that your speed is the median of the speeds of the cars on the highway? Surprisingly, the answer is no!...

From hackers to hacktivists: speed bumps on the global superhighway?

This article traces the emergence of the new social movement of hacktivism from hacking and questions its potential as a source of technologically-mediated radical political action. It assesses hacktivism in the light of critical theories of technology that question the feasibility of reengineering technical systems to more humane ends. The predecessor of hacktivism, hacking, is shown to contai...

Reconciling Speed Limits with Design Speeds

Cancer biomarker discovery: speed-bumps and tire shredders.

In this remarkable era of modern molecular biology we have been fortunate to be able to perform high throughput investigations of cancer-specific DNA sequence variations, RNA expression profiling, proteomics, and metabolomics with tremendous expectations for their application to the early detection and treatment of human cancer. The ease of obtaining such high dimensional data and the throughpu...

Dynamic Interaction Between Heavy Vehicles And Speed Bumps

The paper presents finite element (FE) model development and experimental validation for a truck tractor with a three axle single drop lowboy trailer. The main objective of this research activity was to create a simplified, three dimensional virtual FE model, applicable for computer simulation of dynamic interaction between a vehicle and a bridge or road structure. Such model should provide a r...
