We present, within kohn–sham density functional theory calculations, a quantitative method to identify and assess the partitioning of a large quantum-mechanical system into fragments. We then show how within this framework simple generalizations of other well-known population analyses can be used to extract, from first-principles, reliable electrostatic multipoles for the identified.

The complexity i’m talking about is the unwanted complexity, the complexity that is hidden and is mucking up an organization. There are the strategic causes of unwanted complexity competing in too many customer segments, markets, or geographies, with too many products, services or pricing options.
This procedure includes five steps: (1) definition of the scope of the products and processes to be included in the analysis, (2) grouping of products into a,b, and c categories, (3) identification and quantification of the most important complexity cost factors, (4) identification of initiatives for the possible reduction of complexity costs.
Reduction gear is an arrangement by which an input speed can be lowered for a requirement of slower output speed, with same or more output torque. A reduction gear assembly consists of a set of rotating gears connected to a wheel work. The high speed incoming motion from the wheel work is transmitted to the set of rotating gears, wherein the motion or torque is changed.
Elegance is often invoked as a characteristic of good design, but it cannot be pursued as a design objective because of the absence of actionable definitions that can be translated into design strategies and metrics. In this work, we analyze elegance in the context of systems engineering using a perspective that integrates visual art, gestalt psychology, neuroscience, and complexity theory.

In computability theory and computational complexity theory, a reduction is an algorithm for transforming one problem into another problem. A sufficiently efficient reduction from one problem to another may be used to show that the second problem is at least as difficult as the first. Intuitively, problem a is reducible to problem b if an algorithm for solving problem b efficiently could also be used as a subroutine to solve problem a efficiently.
