To work efficiently, UI data binding has to address input validation and data type mapping. A bound control is a widget whose value is tied or bound to a field in a recordset (e.g., a column in a row of a table). Changes made to data within the control are automatically saved to the database when the control's exit event triggers.
There is a built-in dynamic loader so classes can have dynamic dependencies (loaded on-demand). There are two types of dependencies in ExtJS. Dependencies declared with requires property are loaded before the instance of the class is created. Dependencies defined in uses property might be loaded after the instance of the class is created.
Google designed Angular as a ground-up rewrite of AngularJS. Unlike AngularJS, Angular does not have a concept of "scope" or controllers; instead, it uses a hierarchy of components as its primary architectural characteristic. [7] Angular has a different expression syntax, focusing on "[ ]" for property binding, and "( )" for event binding. [8]
O values. In the 1950s, Harold Urey performed an experiment in which he mixed both normal water and water with oxygen-18 in a barrel, and then partially froze the barrel's contents. The ratio 18 O / 16 O (δ 18 O) can also be used to determine paleothermometry in certain types of fossils. The fossils in question have to show progressive growth ...
Properties may also be classified with respect to the directionality of their nature. For example, isotropic properties do not change with the direction of observation, and anisotropic properties do have spatial variance. It may be difficult to determine whether a given property is a material property or not.
The normalized angle, referred to as angular distance, between any two vectors and is a formal distance metric and can be calculated from the cosine similarity. [5] The complement of the angular distance metric can then be used to define angular similarity function bounded between 0 and 1, inclusive.
A quantity related to inertia is rotational inertia (→ moment of inertia), the property that a rotating rigid body maintains its state of uniform rotational motion. Its angular momentum remains unchanged unless an external torque is applied; this is called conservation of angular momentum. Rotational inertia is often considered in relation to ...
The physical properties of gallium are highly anisotropic, i.e. have different values along the three major crystallographic axes a, b, and c (see table), producing a significant difference between the linear (α) and volume thermal expansion coefficients. The properties of gallium are strongly temperature-dependent, particularly near the ...
