Fallout 4

Fallout 4 is an action role-playing video game developed by Bethesda Game Studios and published by Bethesda Softworks. The fifth major installment in the Fallout series, the game was released worldwide on November 10, 2015 for Microsoft Windows, PlayStation 4, and Xbox One.

It is set in a post-apocalyptic Boston in the year 2287, 210 years after a devastating nuclear war, in which the player character emerges from an underground bunker known as Vault 111. Gameplay is similar to that of Fallout 3 and Fallout: New Vegas. The player completes various quests and acquires experience points to level up their character. With first- and third-person perspectives available, players can explore Fallout 4's open world setting at will, allowing nonlinear gameplay. Companions can accompany the player on their voyages to assist them in battles and help with scavenging. Players have the ability to construct and deconstruct buildings and items, and use them to build a settlement, which can attract and be inhabited by non-playable characters.

Nuclear fallout

Nuclear fallout, or simply fallout, is the residual radioactive material propelled into the upper atmosphere following a nuclear blast or a nuclear reaction conducted in an unshielded facility, so called because it "falls out" of the sky after the explosion and the shock wave have passed. It commonly refers to the radioactive dust and ash created when a nuclear weapon explodes, but such dust can also originate from a damaged nuclear plant. Fallout may take the form of black rain (rain darkened by particulates).

This radioactive dust, consisting of material either directly vaporized by a nuclear blast or charged by exposure, is a highly dangerous kind of radioactive contamination.

Types of fallout

An air burst (that is, a nuclear detonation far above the surface) can eventually produce worldwide fallout. A ground burst can produce possibly much more severe, local fallout.

Global fallout

After an air burst, fission products, un-fissioned nuclear material, and weapon residues vaporized by the heat of the fireball condense into a fine suspension of small particles 10 nm to 20 µm in diameter. These particles may be quickly drawn up into the stratosphere, particularly if the explosive yield exceeds 10 kt.

Humour

Humour (in Commonwealth English), or humor (in American English) is the tendency of particular cognitive experiences to provoke laughter and provide amusement. The term derives from the humoral medicine of the ancient Greeks, which taught that the balance of fluids in the human body, known as humours (Latin: humor, "body fluid"), controlled human health and emotion.

People of all ages and cultures respond to humour. Most people are able to experience humour—be amused, smile or laugh at something funny—and thus are considered to have a sense of humour. The hypothetical person lacking a sense of humour would likely find the behaviour induced by humour to be inexplicable, strange, or even irrational. Though ultimately decided by personal taste, the extent to which a person finds something humorous depends on a host of variables, including geographical location, culture, maturity, level of education, intelligence and context. For example, young children may favour slapstick such as Punch and Judy puppet shows or cartoons such as Tom and Jerry, whose physical nature makes it accessible to them. By contrast, sophisticated forms of humour such as satire require an understanding of its social meaning and context, and thus tend to appeal to the mature audience.

FO4

Fan-out of 4 is a process-independent delay metric used in digital CMOS technologies.

Fan out = C_load / C_in, where

As a delay metric, one FO4 is the delay of an inverter, driven by an inverter 4x smaller than itself, and driving an inverter 4x larger than itself. Both conditions are necessary since input signal rise/fall time affects the delay as well as output loading.

FO4 is generally used as a delay metric because such a load is generally seen in case of tapered buffers driving large loads. Also, for most technologies the optimum fanout for such buffers generally varies from 2.7 to 5.3.

A fan out of 4 is the answer to the canonical problem stated as follows: Given a fixed size inverter, small in comparison to a fixed large load, minimize the delay in driving the large load. After some math, it can be shown that the minimum delay is achieved when the load is driven by a chain of N inverters, each successive inverter ~4x larger than the previous; N ~ log₄(C_load/C_in) .

In the absence of parasitic capacitances (drain diffusion capacitance and wire capacitance), the result is "a fan out of e" (now N ~ ln(C_load/C_in).
