Walking speed

Uses. Intrathecal baclofen can result in decreased spasticity and increased comfort in many people with severe spasticity. This intervention can also result in functional improvements, especially in cases where voluntary motor control was being masked by spasticity.16 Ambulatory patients with spasticity resulting from a CVA, for example, may be able to increase their walking speed and increase their functional mobility after intrathecal baclofen therapy.37,74...

The standard wind-chill formula [Eq. (14)] should not be confused with the standard wind-chill table [66], The standard wind-chill table is based on a standard of calm of 3 mi / h (typical walking speed), rather than on the true standard of calm V = 0 mi / h in true accordance with the standard wind-chill formula [Eq. (14)] that we adopt in this Sect. 4.2. Also, the recommended ranges of applicability of the standard wind-chill table are —50°F < T < 50°F and 3mi/h < V < 110mi /h [66], But we base our calculations of W on the standard wind-chill formula [Eq. (14)], for which no limits on the range of applicability are stated for either T or V [66]. If there is a sufficiently strong wind on Neptune, then Eq. (14) yields a cold negative Kelvin effective wind-chill temperature VV. 

An alternative is to fit a calibrated container, referred to as a Kalibottle (Figure 5.6), to the nozzle and to collect the spray while treating 25 m2. The volume application rate is then read from the side of the bottle. This technique has the advantage when training teams of spray operators, as they can see the effects of walking speed or other changes in application technique. 

The speed of kinesin calculated as a function of the external force showed that applied forces influence the kinesin motion in a rather complicated way (Figure 3.2, left panel) The speed of kinesin shows a maximum at an intermediate external load ( 5pN) and even larger external load slows down the kinesin walking speed, consistent with the experimental results of Carter and Cross [51]. A hindering force slows down the speed of kinesin in the force range of 0 to about 8pN (for [ATP] = 1 mM), without changing the direction of the net motion and the stall force appears to be insensitive to the ATP concentration, which decreases from about 8pN at 5mM of ATP to 7 pN at 5 pM of ATP. 

Take locomotion, for instance. Human walking, which is one form of locomotion, has been found to have a rate of energy expenditure that depends on walking speed (Dean, 1965 Milsum, 1966 Johnson, 2007) ... 

Rate of energy usage = a + fc( walking speed) Dividing by walking speed gives average power per unit speed ... 

The speed of walking is proportional to the product of the number of steps taken in a given time and the length of the step. The step length is proportional to the length of the leg. Thus, the walking speed is... 

Hence, the speed of the natural walk of a person or animal is dependent on the length of the legs. A small animal may move its small legs faster (smaller T), but its walking speed will be slower than that of a tall animal that moves its legs slower. 

Thus, natural walking speed is nearly 21/2 times slower (or 40% as fast) on the Moon. If one tries to walk faster than this, one either stubs a toe or must expend muscular effort. Apollo astronauts on the Moon preferred, instead, to move about in a series of low jumps a few centimeters high (McMahon, 1984). 

There is an optimum speed of walking. Faster than this speed, additional muscular energy is required to propel the body forward. Moving slower than the optimal speed requires additional muscular energy to retard leg movement. Thus, the optimal speed is related to the rate at which the leg can swing forward. Simple analysis of the leg as a physical pendulum shows that the optimal walking speed is related to leg length ... 

Considering the roadway itself and the catastrophic impact, the influencing factors on human walking speed can be seen as a corresponding coefficient to calculate the equivalent length of the lanes when solving the best relief route (Li G 2000, Fu E J Tang A D 2006, Li S L et al. 1999),...

As for evacuation on foot, it is generally thought that the evacuation speed is not affected by road conditions. Therefore, the best evacuation route is the shortest path of actual geographical distance. The evacuation time can be calculated according to the path and average walking speed. In view of related research (Revi A, Singh AK, 2005), in flat area, the evacuation speed on foot is 5 km/h with the old person 4 km/h and child 2 km/h. 

In both cases, the measurements are taken at walking speed as the user pushes the device on the pavement surface. 

The moving reference datum level devices, known as rolling devices, are simpler to operate and the cheapest to acquire. They are pushed at a walking speed (approximately 2 km/h) and consequently have very low daily output. 

The rear axle is loaded to a standard weight similar to the weight used in the Benkelman beam test. The maximum deflection is recorded by electrical transducers located near the beam pivots. When measurements are taken, the beam assembly is pulled forward at approximately twice the speed of the vehicle, to a new position ready for the next measurement. The working speed of the deflectograph is approximately 2 km/h (walking speed) and measurements are taken every 3.8 to 4.0 m. A deflectograph vehicle is shown Figure 16.50. 

The egress time computedimderNFPA 130 requirements does not consider human factors such as panic or initial disorientation and decision-making time moreover, the walking speeds and egress element capacities used in NFPA 130 are fixed values, not dependent by the pedestrian density levels. It is, however, well established that pedestrian flow rates, and thus walking speed, vary considerably according to density levels.
