Product life-cycle management (marketing) A model for the product sales lifecycle, with the assumption of four major phases: introduction, growth, maturity, and decline. Curve of sales as a function of the time of the product on the market. After a plateau in sales at product maturity, a steep decline can follow.
Topological sorting. In computer science, a topological sort or topological ordering of a directed graph is a linear ordering of its vertices such that for every directed edge (u,v) from vertex u to vertex v, u comes before v in the ordering. For instance, the vertices of the graph may represent tasks to be performed, and the edges may ...
Software pipelining. In computer science, software pipelining is a technique used to optimize loops, in a manner that parallels hardware pipelining. Software pipelining is a type of out-of-order execution, except that the reordering is done by a compiler (or in the case of hand written assembly code, by the programmer) instead of the processor.
Some bars and restaurants that got in trouble for breaking the state government's COVID-19 closure orders are still being hounded by the Pennsylvania Liquor Control Board (PLCB). Now, some state ...
Control loop. A control loop is the fundamental building block of control systems in general and industrial control systems in particular. It consists of the process sensor, the controller function, and the final control element (FCE) which controls the process necessary to automatically adjust the value of a measured process variable (PV) to ...
This is the case of the Wilson loop, which is defined as a path-ordered exponential to guarantee that the Wilson loop encodes the holonomy of the gauge connection. The parameter σ that determines the ordering is a parameter describing the contour , and because the contour is closed, the Wilson loop must be defined as a trace in order to be ...
Costas loop. A Costas loop is a phase-locked loop (PLL) based circuit which is used for carrier frequency recovery from suppressed-carrier modulation signals (e.g. double- sideband suppressed carrier signals) and phase modulation signals (e.g. BPSK, QPSK ). It was invented by John P. Costas at General Electric in the 1950s.
Orders for long-lasting U.S. manufactured goods increased more than expected in February, while business spending on equipment showed tentative signs of recovery as the economy's growth prospects ...
