Artifact (video Game)
''Artifact'' is a 2018 digital collectible card game developed and published by Valve Corporation, Valve for Windows, macOS, and Linux. It focuses on online player-versus-player battles and is based on the universe of ''Dota 2'', a multiplayer online battle arena game by Valve. ''Artifact'' was designed by ''Magic: The Gathering'' creator Richard Garfield. While ''Artifact'' gameplay and drafting mechanics received praise, it was criticized for its high learning curve and monetization model, which some saw as pay-to-win. It saw a 95% decline in players within two months of its release, with only around a hundred concurrent players by mid-2019. Valve was surprised by the response, describing it as the largest discrepancy between their expectations for a game and the outcome. Valve reworked the game as ''Artifact 2.0'', altering several features, including removing the need to buy or trade cards with money. It was tested through a closed beta starting in March 2020. A year later, V ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artifact (enterprise Architecture)
Enterprise architecture artifacts, or EA artifacts, are separate documents constituting enterprise architecture.Winter, R. and Fischer, R. (2006), ''Essential Layers, Artifacts, and Dependencies of Enterprise Architecture'', In: Vallecillo, A. (ed.) Proceedings of the 10th IEEE International Enterprise Distributed Object Computing Conference Workshops, Hong Kong, China, pp. 30-37. EA artifacts provide descriptions of an organization from different perspectives important for the various actors involved in strategic decision-making and implementation of IT systems. They can be considered as key elements and cornerstones of an EA practice. Essentially, an EA practice revolves around using specific sets of EA artifacts for improving communication between different actors. Overview EA artifacts are main instruments of an EA practice enabling effective decision-making and IT planning in organizations. The systematic use of EA artifacts for collective decision-making distinguishes a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compression Artifact
A compression artifact (or artefact) is a noticeable distortion of media (including images, audio, and video) caused by the application of lossy compression. Lossy data compression involves discarding some of the media's data so that it becomes small enough to be stored within the desired disk space or transmitted (''streamed'') within the available bandwidth (known as the data rate or bit rate). If the compressor cannot store enough data in the compressed version, the result is a loss of quality, or introduction of artifacts. The compression algorithm may not be intelligent enough to discriminate between distortions of little subjective importance and those objectionable to the user. The most common digital compression artifacts are DCT blocks, caused by the discrete cosine transform (DCT) compression algorithm used in many digital media standards, such as JPEG, MP3, and MPEG video file formats. These compression artifacts appear when heavy compression is applied, and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Artifacting
Composite artifact colors is a designation commonly used to address several graphic modes of some 1970s and 1980s home computers. With some machines, when connected to an NTSC TV or monitor over composite video outputs, the video signal encoding allowed for extra colors to be displayed, by manipulating the pixel position on screen, not being limited by each machine's hardware color palette. This mode was used mainly for games, since it limits the display's effective horizontal resolution. It was most common on the IBM PC (with CGA graphics), TRS-80 Color Computer, Apple II and Atari 8-bit computers, and used famously by the '' Ultima'' role-playing video games. Software titles (such as ''King's Quest'' for the IBM PC) usually provided an option to select between ''"RGB mode"'' and ''"Color Composite mode"''. On PAL displays the effect is also present, but generates more limited colors. Depending on the exact PAL system used results will vary (if PAL-M or PAL-N are use ...

Virtual Artifact
A virtual artifact (VA) is an immaterial object that exists in the human mind or in a digital environment, for example the Internet, intranet, virtual reality, cyberspace, etc. Background The term "virtual artifact" has been used in a variety of ways in scientific and public discourse. Previously it has referred to objects of different nature (e.g. images, user interfaces, models, prototypes, computer animationvirtual books that exist in digital environments. The concept behind the term is rapidly developing and expanding as new phenomena emerge in the virtual domain. History of the phenomenon Imaginary worlds, characters, items, etc. have been described in stories and tales since the dawn of humanity. In the philosophic discourse, utopias have existed where extensive systems and their components have been depicted in detail. Imaginary artifacts have been described and created in terms of language and visual presentation. The development of the visual presentation techniques (e. ...

Artifact (archaeology)
An artifact, or artefact (see American and British English spelling differences), is a general term for an item made or given shape by humans, such as a tool or a work of art, especially an object of archaeological interest. In archaeology, the word has become a term of particular nuance and is defined as an object recovered by archaeological endeavor, which may be a cultural artifact having cultural interest. Artifact is the general term used in archaeology, while in museums the equivalent general term is normally "object", and in art history perhaps artwork or a more specific term such as "carving". The same item may be called all or any of these in different contexts, and more specific terms will be used when talking about individual objects, or groups of similar ones. Artifacts exist in many different forms and can sometimes be confused with ecofacts and features; all three of these can sometimes be found together at archaeological sites. They can also exist in different t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artifact (film)
''Artifact'' is a 2012 American documentary film directed by Jared Leto under the pseudonym of Bartholomew Cubbins. It was produced by Leto and Emma Ludbrook through their production company Sisyphus. ''Artifact'' chronicles the modern music business as it charts the legal dispute between Leto's rock band Thirty Seconds to Mars and record label EMI, which filed a $30 million breach of contract lawsuit against them in 2008, after the band tried to exit its contract over a royalties dispute. Thirty Seconds to Mars is shown working with producer Flood to create the 2009 album ''This Is War'', meeting with lawyers between recording sessions. ''Artifact'' had its world premiere at the 2012 Toronto International Film Festival where it received the People's Choice Award for Best Documentary. Critics praised the examination of the state of the modern music industry and its focus on the relationship between artists and record companies. The film received a limited theatrical release beginn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artifact (error)
In natural science and signal processing, an artifact or artefact is any error An error (from the Latin ''error'', meaning "wandering") is an action which is inaccurate or incorrect. In some usages, an error is synonymous with a mistake. The etymology derives from the Latin term 'errare', meaning 'to stray'. In statistics ... in the perception or representation of any information introduced by the involved equipment or technique(s). Computer science In ''computer science'', digital artifacts are anomalies introduced into digital signals as a result of digital signal processing. Microscopy In ''microscopy'', visual artifacts are sometimes introduced during the processing of samples into microscopic slide, slide form. Econometrics In ''econometrics'', which trades on computing relationships between related Variable (mathematics), variables, an artifact is a spurious finding, such as one based on either a faulty choice of variables or an over-extension of the computed relati ...

Artifact (software Development)
An artifact is one of many kinds of ''tangible'' by-products produced during the development of software. Some artifacts (e.g., use cases, class diagrams, and other Unified Modeling Language (UML) models, requirements and design documents) help describe the function, architecture, and design of software. Other artifacts are concerned with the process of development itself—such as project plans, business cases, and risk assessments. The term ''artifact'' in connection with software development is largely associated with specific development methods or processes e.g., Unified Process. This usage of the term may have originated with those methods. Build automation, Build tools often refer to source code compiled for testing as an artifact, because the executable is necessary to carrying out the testing plan. Without the executable to test, the testing plan artifact is limited to non-execution based testing. In non-execution based testing, the artifacts are the Software walkthroug ...

Cultural Artifact
A cultural artifact, or cultural artefact (see American and British English spelling differences), is a term used in the social sciences, particularly anthropology, ethnology and sociology for anything created by humans which gives information about the culture of its creator and users. ''Artifact'' is the spelling in North American English; ''artefact'' is usually preferred elsewhere. Cultural artifact is a more generic term and should be considered with two words of similar, but narrower, nuance: it can include objects recovered from archaeological sites, i.e. archaeological artifacts, but can also include objects of modern or early-modern society, or social artifacts. For example, in an anthropological context: a 17th-century lathe, a piece of faience, or a television each provides a wealth of information about the time in which they were manufactured and used. Cultural artifacts, whether ancient or current, have a significance because they offer an insight into: techno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Artifact
Digital artifact in information science, is any undesired or unintended alteration in data introduced in a digital process by an involved technique and/or technology. Digital artifact can be of any content types including text, audio, video, image, animation or a combination. Information science In information science, digital artifacts result from: *Hardware malfunction: In computer graphics, visual artifacts may be generated whenever a hardware component such as the processor, memory chip, cabling malfunctions, etc., corrupts data. Examples of malfunctions include physical damage, overheating, insufficient voltage and GPU overclocking. Common types of hardware artifacts are texture corruption and T-vertices in 3D graphics, and pixelization in MPEG compressed video. *Software malfunction: Artifacts may be caused by algorithm flaws such as decoding/encoding audio or video, or a poor pseudo-random number generator that would introduce artifacts distinguishable from the desi ...
