process

Chemical Engineering
  • 1. Refers to the changes from one equilibrium state, or steady state, to another that take place within a system. For example, in a heating process, heat is transferred to the system from the surroundings.

    2. A term used in process control to describe the collective functions performed in and by the process in which the process variables such as temperature, pressure, flow, and level are controlled.

    3. A shorthand for chemical process, which is a collective description of the way that useful chemical products are manufactured from raw materials through chemical, physical, or biochemical means.


Computer
  • 1. (task) A stream of activity. A process is defined by its code, i.e. the ordered set of machine instructions defining the actions that the process is to take, the contents of its workspace, i.e. the set of data values that it can read, write, and manipulate, and its process descriptor, which defines the current status of any resources that are allocated to the process.

    2. To carry out the actions defined by the sequence of instructions that make up the code of a program.


Philosophy
  • A sequence of events. In the process philosophy of Whitehead, the fundamental fact of cosmology is the unfolding of processes, not conceived in terms of modifications of underlying substances, but united by networks of relations, and selected in advance by God. A process theory of mind sees its unity not in terms of underlying substance (see personal identity) but as the relatively permanent form or pattern displayed by continuously changing processes, just as a wave maintains its form although it is constituted by different volumes of water at different times. Process theology, again stemming from Whitehead and Charles Hartshorne, develops a concept of God as involved in unfolding processes in a way that brings him into contact with the ordinary human mess without actually being responsible for it.
