The effect of voluntary speed reduction criteria on attainable ship speed
2015The reasons for ship speed reduction in a seaway may generally be divided into two categories: natural reasons, such as the added resistance due to wind and waves, change of wake field and loss of thrust ; technical or “design” reasons that are controlled by the shipmaster, such as very large motion amplitudes, velocities and accelerations, slamming ...

Measuring the Impacts of Speed Reduction Technologies
Transportation Research Record: Journal of the Transportation Research Board, 2005This paper presents the results of a quantitative and qualitative evaluation of a dynamic curve warning system deployed at one site on Interstate 5 in Oregon. On a dynamic message sign, the system displays messages directed to drivers on the basis of the observed speed of approaching vehicles.

High-Speed Algorithms and Architectures for Range Reduction Computation
IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2011Range reduction is a crucial step for accuracy in trigonometric functions evaluation. This paper shows and compares a set of algorithms for additive range reduction computation and their corresponding application-specific integrated circuit implementations (ensuring an accuracy of one unit in the last place).

Speed Reduction Mechanisms of Transverse Lines
Transportation Human Factors, 2000The psychological mechanisms responsible for speed reductions caused by transverse lines were investigated. Using a driving simulator, 24 experienced drivers drove toward intersections with transverse lines at both reducing and constant spacing, with lines extending 0.6 m from the lane edges (peripheral transverse lines), and no lines (control), both ...

SPEED REDUCTION UNIT WITH BEARING
1995In a speed reduction unit adapted for attachment to a load-bearing structure (1) of a consumer through its casing (4), and being provided with bearings (17, 18) for supporting the output shaft (14) as well as the consumer itself, the casing (4) is secured on the load-bearing structure (1) through an intervening swing mount (20; 30) making for easier ...

The Reduction of Sights in High Speed Aircraft
Journal of Navigation, 1949When designing the periscopic sextant now coming into production it was realized that the conditions in the pressurized aircraft for which this sextant was designed differed sufficiently from those previously experienced to make it worth while reconsidering what methods would be most applicable to the new combination of pressurized aircraft and ...
