Speed enforcement and speed choice
Accident Analysis & Prevention, 1982Abstract A rational appraoch to practical problems of speed enforcement requires an understanding of the manner in which enforcement affects speed choice. In this report, four experiments are described. Each experiment consisted of measuring speeds of vehicles before, during and after enforcement took place, accompanied by a control section to which ...

Speed testing without speed tests
Proceedings of the 10th ACM SIGCOMM conference on Internet measurement, 2010How fast is the network? The speed at which real users can download content at different locations and at different times is an important metric for service providers. Knowledge of this speed helps determine where to provision more capacity and helps detect network problems. However, most network-level estimates of these speeds today are obtained using

Proceedings of the 23rd Conference on l'Interaction Homme-Machine, 2011
We present the SPEED method to predict endpoints, based on analysis of the kinetic characteristics of the pointing gesture. Our model splits the gesture into an acceleration phase and a deceleration phase to precisely detect target. The first phase allows us to identify a velocity peak that marks the beginning of the second phase.

ACM SIGPLAN Notices, 2009
This paper describes an inter-procedural technique for computing symbolic bounds on the number of statements a procedure executes in terms of its scalar inputs and user-defined quantitative functions of input data-structures. Such computational complexity bounds for even simple programs are usually disjunctive, non-linear, and involve numerical ...

ET a broadcasting link between radio station and radio car; a global satellite navigation signal tracking the location of a ship; or an electric railway signal alerting train drivers about the status of the line ahead. A more recent trend has seen the design of transport applications that rely on a variety of communications techniques.

In “Speed Lines: Futurism and Superheroes,” Daniel Worden reads the superhero as a quintessentially modernist trope, arguing that superheroes participate in both modernism’s visual, formal experimentation and in its problematic fascination with fascist politics.

A Fluidic Low-Speed Air-Speed Indicator
Journal of Aircraft, 1970Crossflow and parallel flow techniques were investigated. The parallel flow technique was chosen. A prototype has been wind-tunnel tested. It has a near linear response from 0.3 to 90 fps. This sensor is light in weight, simple in operation and has no moving parts. Efforts are underway to optimize the sensor performance and develop a flightworthy unit.

Sex Differences in Clerical Speed: Perceptual Speed versus Comparison and Decision Speed
Perceptual and Motor Skills, 1977The hypothesis that sex differences in clerical speed are based on differences in perceptual speed was tested in an experiment using tachistoscopic presentation of pairs of items requiring same-different judgments. This procedure eliminated the attentional shifts from item to item as well as the repetitive nature of the task.
