Modal windows are sometimes called heavy windows or modal dialogs because they often display a dialog box. User interfaces typically use modal windows to command user awareness and to display emergency states, though interaction designers argue they are ineffective for that use. [1] Modal windows are prone to mode errors. [1] [2] [3]
Values greater than 5/9 may indicate a bimodal or multimodal distribution, though corresponding values can also result for heavily skewed unimodal distributions. [28] The maximum value (1.0) is reached only by a Bernoulli distribution with only two distinct values or the sum of two different Dirac delta functions (a bi-delta distribution).
Modal analysis is the study of the dynamic properties of systems in the frequency domain. It consists of mechanically exciting a studied component in such a way to target the modeshapes of the structure, and recording the vibration data with a network of sensors.
Modal logic is a kind of logic used to represent statements about necessity and possibility.It plays a major role in philosophy and related fields as a tool for understanding concepts such as knowledge, obligation, and causation.
Modal impact hammer with interchangeable tips and accompanying temporal and frequency responses. An ideal impact to a structure is a perfect impulse, which has an infinitely small duration, causing a constant amplitude in the frequency domain; this would result in all modes of vibration being excited with equal energy. The impact hammer test is ...
Modal share is an important component in developing sustainable transport within a city or region. In recent years, many cities have set modal share targets for balanced and sustainable transport modes, particularly 30% of non-motorized ( cycling and walking ) and 30% of public transport .
A modal filter, sometimes referred to as a point closure, [1] is a road design that restricts the passage of certain types of vehicle in road transport. Modal filtering is often used to help create a low traffic neighbourhood (LTN), where motor traffic is diverted away from residential streets [ 2 ] [ 3 ] and instead toward feeder roads .
In modal logic, modal collapse is the condition in which every true statement is necessarily true, and vice versa; that is to say, there are no contingent truths, or to put it another way, that "everything exists necessarily" [1] [2] (and likewise if something does not exist, it cannot exist).
