The Dramatic Imagination is a book written in 1941 by American scenic designer Robert Edmond Jones.\nIt is considered the basic blueprint from which all innovations of modern stage design have been crafted. |
| Unexplained wealth of the Marcos family |
The Marcos family, a political family in the Philippines, owns various assets that Philippine courts have determined to have been acquired through ilicit means during the presidency of Ferdinand Marcos from 1965–1986. These assets are referred to using several terms, including "ill-gotten wealth" and "unexplained wealth," while some authors such as Philippine Senator Jovito Salonga and Belinda Aquino more bluntly refer to it as the "Marcos Plunder."Legally, the Philippine Supreme Court defines this "ill-gotten wealth" as the assets the Marcoses acquired beyond the amount legally declared by Ferdinand and Imelda Marcos in the president's statements of assets and liabilities—only about US$13,500.00 worth from his salary as president. |
| In-system programming |
In-system programming (ISP), or also called in-circuit serial programming (ICSP), is the ability of some programmable logic devices, microcontrollers, and other embedded devices to be programmed while installed in a complete system, rather than requiring the chip to be programmed prior to installing it into the system. It also allows firmware updates to be delivered to the on-chip memory of microcontrollers and related processors without requiring specialist programming circuitry on the circuit board, and simplifies design work.There is no standard for in-system programming protocols for programming microcontroller devices. |
| Heat capacity |
Heat capacity or thermal capacity is a physical property of matter, defined as the amount of heat to be supplied to an object to produce a unit change in its temperature. The SI unit of heat capacity is joule per kelvin (J/K). |

Investors are repaid from the principal and interest cash flows collected from the underlying debt and redistributed through the capital structure of the new financing. |
| Causality conditions |
In the study of Lorentzian manifold spacetimes there exists a hierarchy of causality conditions which are important in proving mathematical theorems about the global structure of such manifolds. These conditions were collected during the late 1970s.The weaker the causality condition on a spacetime, the more unphysical the spacetime is. |
| Conditions races |
Conditions races are horse races in which the weights carried by the runners are laid down by the conditions attached to the race. Weights are allocated according to the sex of the runners, with female runners carrying less weight than males; the age of the runners, with younger horses receiving weight from older runners to allow for relative maturity, referred to as weight for age; and the quality of the runners, with horses that have won certain values of races giving weight to less successful entrants. |

The Payment Card Industry Data Security Standard (PCI DSS) is an information security standard for organizations that handle branded credit cards from the major card schemes.\nThe PCI Standard is mandated by the card brands but administered by the Payment Card Industry Security Standards Council. |
| Supercavitation |
Supercavitation is the use of a cavitation bubble to reduce skin friction drag on a submerged object and enable high speeds. Applications include torpedoes and propellers, but in theory, the technique could be extended to an entire underwater vessel. |
| Publicly traded private equity |
Publicly traded private equity (also referred to as publicly quoted private equity or publicly listed private equity) refers to an investment firm or investment vehicle, which makes investments conforming to one of the various private equity strategies, and is listed on a public stock exchange.\nThere are fundamentally two separate opportunities that private equity firms pursued in the public markets. |

Manufacturing engineering is a branch of professional engineering that shares many common concepts and ideas with other fields of engineering such as mechanical, chemical, electrical, and industrial engineering. \nManufacturing engineering requires the ability to plan the practices of manufacturing; to research and to develop tools, processes, machines and equipment; and to integrate the facilities and systems for producing quality products with the optimum expenditure of capital.The manufacturing or production engineer's primary focus is to turn raw material into an updated or new product in the most effective, efficient & economic way possible. |
