Design Studio
A studio is a space set aside for creative work of any kind, including art, dance, music and theater. The word ''studio'' is derived from the , from , from ''studere'', meaning to study or zeal. Types Art The studio of any artist, especially from the 15th to the 19th centuries, characterized all the assistants, thus the designation of paintings as "from the workshop of..." or "studio of..." An art studio is sometimes called an " atelier", especially in earlier eras. In contemporary, English language use, "atelier" can also refer to the Atelier Method, a training method for artists that usually takes place in a professional artist's studio. The above-mentioned "method" calls upon that zeal for study to play a significant role in the production which occurs in a studio space. A studio is more or less artful to the degree that the artist who occupies it is committed to the continuing education in his or her formal discipline. Academic curricula categorize studio classes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Downloading
In computer networks, download means to ''receive'' data from a remote system, typically a server such as a web server, an FTP server, an email server, or other similar systems. This contrasts with uploading, where data is ''sent to'' a remote server. A ''download'' is a file offered for downloading or that has been downloaded, or the process of receiving such a file. Definition Downloading generally transfers entire files for local storage and later use, as contrasted with streaming, where the data is used nearly immediately while the transmission is still in progress and may not be stored long-term. Websites that offer streaming media or media displayed in-browser, such as YouTube, increasingly place restrictions on the ability of users to save these materials to their computers after they have been received. Downloading on computer networks involves retrieving data from a remote system, like a web server, FTP server, or email server, unlike uploading, where data is sent to ...

Arrow Keys
Arrow keys or cursor movement keys are keys on a computer keyboard that are either programmed or designated to move the cursor (computers), cursor in a specified direction. The term "cursor movement key" is distinct from "arrow key" in that the former term may refer to any of various keys on a computer keyboard designated for cursor movement, whereas "arrow keys" generally refers to one of four specific keys, typically marked with arrows. Arrow keys are typically located at the bottom of the keyboard to the left side of the numeric keypad, usually arranged in an inverted-T layout but also found in diamond shapes and linear shapes. Arrow keys are commonly used for navigating around documents and for playing games. The inverted-T layout was popularized by the Digital Equipment Corporation LK201 keyboard from 1982. Historical development Before the computer mouse was widespread, arrow keys were the primary way of moving a cursor on screen. Mouse keys is a feature that allows c ...

Thumb Signal
A thumb signal, usually described as a thumbs-up or thumbs-down, is a common hand gesture achieved by a closed fist held with the thumb extended upward or downward, respectively. The thumbs-up gesture is associated with positivity, approval, achievement, satisfaction and solidarity, while the thumbs-down gesture is associated with concern, disapproval, dissatisfaction, rejection and failure. History Ancient Rome The Latin phrase ''pollice verso'' is used in the context of gladiatorial combat for a hand gesture used by Ancient Roman crowds to pass judgment on a defeated gladiator. While it is clear that the thumb was involved, the precise type of gesture described by the phrase ''pollice verso'' and its meaning are unclear in the historical and literary record. According to Anthony Corbeill, a classical studies professor who has extensively researched the practice, thumbs up signalled killing the gladiator while "a closed fist with a wraparound thumb" meant sparing him.< ...

Logical NOR
In Boolean logic, logical NOR, non-disjunction, or joint denial is a truth-functional operator which produces a result that is the negation of logical or. That is, a sentence of the form (''p'' NOR ''q'') is true precisely when neither ''p'' nor ''q'' is true—i.e. when both ''p'' and ''q'' are ''false''. It is logically equivalent to \neg(p \lor q) and \neg p \land \neg q, where the symbol \neg signifies logical negation, \lor signifies OR, and \land signifies AND. Non-disjunction is usually denoted as \downarrow or \overline or X (prefix) or \operatorname. As with its dual, the NAND operator (also known as the Sheffer stroke—symbolized as either \uparrow, \mid or /), NOR can be used by itself, without any other logical operator, to constitute a logical formal system (making NOR functionally complete). The computer used in the spacecraft that first carried humans to the moon, the Apollo Guidance Computer, was constructed entirely using NOR gates with three inputs ...

Combinatorial Game Theory
Combinatorial game theory is a branch of mathematics and theoretical computer science that typically studies sequential games with perfect information. Research in this field has primarily focused on two-player games in which a ''position'' evolves through alternating ''moves'', each governed by well-defined rules, with the aim of achieving a specific winning condition. Unlike game theory, economic game theory, combinatorial game theory generally avoids the study of games of chance or games involving imperfect information, preferring instead games in which the current state and the full set of available moves are always known to both players. However, as mathematical techniques develop, the scope of analyzable games expands, and the boundaries of the field continue to evolve. Authors typically define the term "game" at the outset of academic papers, with definitions tailored to the specific game under analysis rather than reflecting the field’s full scope.

Sign
A sign is an object, quality, event, or entity whose presence or occurrence indicates the probable presence or occurrence of something else. A natural sign bears a causal relation to its object—for instance, thunder is a sign of storm, or medical symptoms a sign of disease. A conventional sign signifies by agreement, as a full stop signifies the end of a sentence; similarly the words and expressions of a language, as well as bodily gestures, can be regarded as signs, expressing particular meanings. The physical objects most commonly referred to as signs (notices, road signs, etc., collectively known as signage) generally inform or instruct using written text, symbols, pictures or a combination of these. The philosophical study of signs and symbols is called semiotics; this includes the study of semiosis, which is the way in which signs (in the semiotic sense) operate. Nature Semiotics, epistemology, logic, and philosophy of language are concerned about the nature of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relative Direction
In geometry, direction, also known as spatial direction or vector direction, is the common characteristic of all ray (geometry), rays which coincide when translation (geometry), translated to share a common endpoint; equivalently, it is the common characteristic of vector (geometry), vectors (such as the relative position between a pair of points) which can be made equal by scaling (geometry), scaling (by some positive scalar multiplication, scalar multiplier). Two vectors sharing the same direction are said to be ''codirectional'' or ''equidirectional''. All codirectional line segments sharing the same size (length) are said to be ''equipollent (geometry), equipollent''. Two equipollent segments are not necessarily coincident; for example, a given direction can be evaluated at different starting Position (geometry), positions, defining different unit directed line segments (as a bound vector instead of a free vector). A direction is often represented as a unit vector, the res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Downgrade
In computing, downgrading refers to reverting software (or hardware) back to an older version; downgrade is the opposite of upgrade. Programs may need to be downgraded to remove introduced bugs, restore useful removed features, and to increase speed and/or ease of use. The same can occur with machinery. An example of a downgraded program is Gmax, a downgraded version of 3ds max used by professional computer graphics artists, free to download and simplified for ease of use. The term "downgrade" became especially popularized during the days of Windows Vista, with users wanting to return to, or downgrade to (with some even calling it an "upgrade") Windows XP due to Vista's performance and familiarity issues.InfoWorlBursting the Vista sales bubble: metrics show 35% of enterprise-class users downgrade from Vista to XP Retrieved on 2009-12-20 Another reason could be that the user's applications do not support their new OS and they want to revert to an older version.
