In robotics the common normal of two non-intersecting joint axes is a line perpendicular to both axes. [1] The common normal can be used to characterize robot arm links, by using the "common normal distance" and the angle between the link axes in a plane perpendicular to the common normal. [2] When two consecutive joint axes are parallel, the ...

Standard normal table. In statistics, a standard normal table, also called the unit normal table or Z table, [ 1] is a mathematical table for the values of Φ, the cumulative distribution function of the normal distribution. It is used to find the probability that a statistic is observed below, above, or between values on the standard normal ...
Although many fears are learned, the capacity to fear is part of human nature. Many studies [10] have found that certain fears (e.g. animals, heights) are much more common than others (e.g. flowers, clouds). These fears are also easier to induce in the laboratory. This phenomenon is known as preparedness.
Although fears are common and normal, a phobia is an extreme type of fear where great lengths are taken to avoid being exposed to the particular danger. Phobias are considered the most common psychiatric disorder, affecting about 10% of the population in the US, [ 3 ] according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth ...

The Portuguese portolan charts come from the Majorcan tradition, [18] and as traditional portolan charts did not fulfill the requirements demanded by the expansion of the geographic horizons attained by Portuguese and Spaniards, they superposed the astronomical lines of the equator and tropics on top of the wind line network, and they continued ...
Figure 2: Weight (W), the frictional force (F r), and the normal force (F n) acting on a block.Weight is the product of mass (m) and the acceleration of gravity (g).In the case of an object resting upon a flat table (unlike on an incline as in Figures 1 and 2), the normal force on the object is equal but in opposite direction to the gravitational force applied on the object (or the weight of ...
