Acceleration measurements were determined by differentiating data collected using the same equipment. Typical stopping distances were found to be 125 ft to 160 ft (38.1 m to 48.8 m) at 30 mph (48 km/h) and 180 ft to 225 ft (54.9 m to 68.6 m) at 40 mph (64 km/h). For the range...
A new method of determining distances to dark globules. The distance to B 335 Instead, we use a scheme that allows independent determination of the extinction in each line of sight as determined by groups of adjacent stars. The ... S Olofsson,G Olofsson - 《Astronomy & Astrophysics》 被引...
Stopping sight distance is the sum of two distances: (1) the distance traversed by the vehicle from the instant the driver sights an object necessitating a stop to the instant the brakes are applied, and (2) the distance needed to stop the vehicle from the instant brake application begins. ...
The stopping distance sstop is determined using the following formula:where shr is the human perception distance, shr is the human reaction distance, sbrl is the brake lag distance, and sbr is the braking distance. These distances are discussed below....
The comparison is made in the Fourier plane, computing the Euclidean distances between modules of the spatial frequencies components of the images. We propose then to use the results of ISRA and RLA at the iteration number corresponding to the minimum of that distance. The technique is checked ...
are smaller in size than photosensitive surfaces of the photosensitive elements. The dimension of the apertures, the dimension of the photosensitive surfaces of the photosensitive elements and the distances between the first stopping plate, the second stopping plate and the photosensitive elements are ...
Commonly, track-structure simulations for ions are based on interaction cross sections obtained by scaling those of protons13,26; scaling factor is the effective charge squared, determined usually by the Barkas formula27. However, at low energies where each slowing-down particle passes through a ...
by the incident beam spot on the detector. In Fig.2a, tracks recorded on CR39 film are displayed for ions passing through the system with/without target. When the plasma target is inserted, only protons are observed in the TPS. The deflection distances of protons without/with target are ...
It was an utterly chaotic scene: thousands of refugees arriving daily and nowhere to put them. "People were just standing on the roadside, they had travelled long distances, they were injured, some were carrying other people, and there was no food or anything." ...
