1 In the context of object linking and embedding, information such as a drawing which may be linked or embedded into another document. 2 In the context of object oriented programming, a combination of variables, data structures and procedures stored as an entity called a 'method
Translated version of a program which has been assembled or compiled. Cf source code,
A method to share and transfer information between application programs, eg a drawing may be embedded into a text document,
An approach to programming using the concept of an object. The approach uses a hierarchical object structure which reflects the system to be modelled. Programming languages offering this approach include Smalltalk, modula-2, C++ and some versions of Pascal. Abbrev OOP.
Knowledge of the continued existence of an object, even when the object is not accessible to direct sensory awareness. According to J Piaget this ability does not develop until infants are approximately eight months or more. Also object constancy.
Usually the lens of an optical system nearest the object. Abbrev OG, objective glass for microscope work.
A method of processing the original observations by computer to give all values of the atmospheric variables needed to produce a numerical forecast, in contrast to a subjective analysis made by scrutinizing observations plotted on charts. The computer programs, after checking for transmission and other errors, produce interpolated grid-point values dynamically con
Sound level meter in which noise level to be measured operates a microphone, amplifier and detector, the last named indicating noise level on the phon scale. The apparatus is previously calibrated with known intensities of the reference tone, 1 kHz, suitable weighting networks and an integrating circuit being incorporated in the amplifier to simulate relevant properties of the ear in appreciating noise,
A narrow-angle ca 1 prism placed in front of the objective lens or primary mirror of a telescope, which causes the image of each star to give a small spectrum. Those of many objects within a small field can thus be recorded simultaneously, either photographic
