ORGANIZATIONAL REENGINEERING

[SYS ENG] The study, capture, and modification of the internal mechanisms or functionality of existing system management processes and practices in an organization in order to reconstitute them in a new form and with new features, often to take advantage of newly emerged organizational competitiveness requirements, but without changing the inherent purpose of the organization itself. Also known as systems management reengineering.

NICHOLSON'S HYDROMETER

A modification of Fahrenheit's hydrometer in which the lower end of the instrument carries a scale pan to permit the determination of the relative density of a solid.

MORGAN EQUATION

A modification of the Ramsey-Shields equation, in which the expression for the molar surface energy is set equal to a quadratic function of the temperature rather than to a linear one.

MODIFICATION

A major or minor change in the design of an item, effected in order to correct a deficiency, to facilitate production, or to improve operational effectiveness.

METER-TON-SECOND SYSTEM

A modification of the meter-kilogram-second system in which the metric ton (1000 kilograms) replaces the kilogram as the unit of mass.

LINEARIZATION

1. The modification of a system so that its outputs are approximately linear functions of its inputs, in order to facilitate analysis of the system. 2. The mathematical approximation of a nonlinear system, whose departures from linearity are small, by a linear system corresponding to small changes in the varilimited-pressure cycle See mixed cycle.

JET BIT

A modification of a drag bit or a roller bit that utilizes the hydraulic jet principle to increase drilling rate.

HOLLOW-ROD DRILLING

A modification of wash boring in which a check valve is introduced at the bit so that the churning action may be also used to pump the cuttings up the drill rods.

COMPOSITE SAILING

A modification of great-circle sailing used when it is desired to limit the highest latitude. The composite track consists of a great circle from the point of departure and tangent to the limiting parallel, a course line along the parallel, and a great circle tangent to the limiting parallel to the destination. Composite sailing applies only when the vertex lies between the point of departure and destination.

SEA TRIALS

A series of trials done at sea to determine whether the ship has met the specifications of design, modification, or repair
