Content-Control Software
Content-control software, commonly referred to as an Internet filter, is software that restricts or controls the content an Internet user is capable to access, especially when utilised to restrict material delivered over the Internet via the Web, Email, or other means. Content-control software determines what content will be available or be blocked. Such restrictions can be applied at various levels: a government can attempt to apply them nationwide (see Internet censorship), or they can, for example, be applied by an ISP to its clients, by an employer to its personnel, by a school to its students, by a library to its visitors, by a parent to a child's computer, or by an individual user to their own computer. The motive is often to prevent access to content which the computer's owner(s) or other authorities may consider objectionable. When imposed without the consent of the user, content control can be characterised as a form of internet censorship. Some content-control software includes time control functions that empowers parents to set the amount of time that child may spend accessing the Internet or playing games or other computer activities. In some countries, such software is ubiquitous. In Cuba, if a computer user at a government-controlled Internet cafe types certain words, the word processor or web browser is automatically closed, and a "state security" warning is given.

Fallout Shelter (Video Game)
Fallout Shelter is a free-to-play simulation video game developed by Bethesda Game Studios, with assistance by Behaviour Interactive, and published by Bethesda Softworks. Part of the Fallout series, it was released worldwide for iOS devices in June 2015, for Android devices in August 2015, for Microsoft Windows in July 2016, Xbox One in February 2017, and PlayStation 4 and Nintendo Switch in June 2018. The game is also available on Tesla vehicles. The game tasks the player with building and effectively managing their own Vault, a fallout shelter. Upon release, Fallout Shelter received mostly positive reviews. Critics enjoyed the game's extension of the Fallout universe, the core gameplay, and its visual style. Common criticisms included the game's lack of depth, its use of unnecessary microtransactions, and its lack of an ending. The game grossed US$5.1 million (equivalent to about $5.5M in 2019) in microtransaction sales in the first two weeks after its release. While Fallout Shelter is a single-player experience, a multiplayer board game adaptation of the game was released about five years after its original release.

Cinnamon (Desktop Environment)
Cinnamon is a free and open-source desktop environment for the X Window System that derives from GNOME 3 but follows traditional desktop metaphor conventions. Cinnamon is the principal desktop environment of the Linux Mint distribution and is available as an optional desktop for other Linux distributions and other Unix-like operating systems as well. The development of Cinnamon began as a reaction to the April 2011 release of GNOME 3 in which the conventional desktop metaphor of GNOME 2 was abandoned in favor of GNOME Shell. Following several attempts to extend GNOME 3 such that it would suit the Linux Mint design goals, the Mint developers forked several GNOME 3 components to build an independent desktop environment. Separation from GNOME was completed in Cinnamon 2.0, which was released in October 2013. Applets and desklets are no longer compatible with GNOME 3. As the distinguishing factor of Linux Mint, Cinnamon has generally received favorable coverage by the press, in particular for its ease-of-use and gentle learning curve. With respect to its conservative design model, Cinnamon is similar to the Xfce and GNOME 2 (MATE and GNOME Flashback/Classic) desktop environments.

Crowd Counting
Crowd counting refers to estimating the number of individuals who share a certain region. This work present a survey for the main methods that calculate how many individuals are in a physical region. We start by reviewing traditional computer vision methods and then review deep learning-based methods.

VC Dimension
In Vapnik–Chervonenkis theory, the VC dimension (for Vapnik–Chervonenkis dimension) is a measure of the capacity (complexity, expressive power, richness, or flexibility) of a space of functions that can be learned by a statistical classification algorithm. It is defined as the cardinality of the largest set of points that the algorithm can shatter. It was originally defined by Vladimir Vapnik and Alexey Chervonenkis. Formally, the capacity of a classification model is related to how complicated it can be. For example, consider the thresholding of a high-degree polynomial: if the polynomial evaluates above zero, that point is classified as positive, otherwise as negative. A high-degree polynomial can be wiggly, so it can fit a given set of training points well. But one can expect that the classifier will make errors on other points, because it is too wiggly. Such a polynomial has a high capacity. A much simpler alternative is to threshold a linear function. This function may not fit the training set well, because it has a low capacity. This notion of capacity is made rigorous below.

Core (Game Theory)
In cooperative game theory, the core is the set of feasible allocations that cannot be improved upon by a subset (a coalition) of the economy's agents. A coalition is said to improve upon or block a feasible allocation if the members of that coalition are better off under another feasible allocation that is identical to the first except that every member of the coalition has a different consumption bundle that is part of an aggregate consumption bundle that can be constructed from publicly available technology and the initial endowments of each consumer in the coalition. An allocation is said to have the core property if there is no coalition that can improve upon it. The core is the set of all feasible allocations with the core property.

Sine
In mathematics, the sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle (the hypotenuse). For an angle [math]\displaystyle{ x }[/math], the sine function is denoted simply as [math]\displaystyle{ \sin x }[/math]. More generally, the definition of sine (and other trigonometric functions) can be extended to any real value in terms of the length of a certain line segment in a unit circle. More modern definitions express the sine as an infinite series, or as the solution of certain differential equations, allowing their extension to arbitrary positive and negative values and even to complex numbers. The sine function is commonly used to model periodic phenomena such as sound and light waves, the position and velocity of harmonic oscillators, sunlight intensity and day length, and average temperature variations throughout the year. The function sine can be traced to the jyā and koṭi-jyā functions used in Gupta period Indian astronomy (Aryabhatiya, Surya Siddhanta), via translation from Sanskrit to Arabic, and then from Arabic to Latin. The word "sine" (Latin "sinus") comes from a Latin mistranslation by Robert of Chester of the Arabic jiba, which is a transliteration of the Sanskrit word for half the chord, jya-ardha.
