A laser vaporization cluster source produces ions using a combination of laser desorption ionization and supersonic expansion. The Smalley source (or Smalley cluster source) was developed by Richard Smalley at Rice University in the 1980s and was central to the discovery of fullerenes in 1985.
Television viewers distinguish between the credibility of official (or elite) and citizen (or nonelite) sources. Expert ratings alter subjects' judgments of source credibility. Race does not affect credibility. Debate about the credibility of elite versus nonelite sources dates back to at least the 1920s. Walter Lippmann argued in favor of elite sources in his 1922 book Public Opinion. John Dewey argued citizens are credible sources in his 1927 book The Public and its Problems. Elite, male sources outnumber nonelite, female and minority sources in American journalism. Television news viewers perceive stories with elite sources as significantly more credible than stories with nonelite sources. Source titles and manner of dress played a larger role in viewer estimations of credibility than did either race or even what the sources said on air.
In June 2015, Valve announced that the entirety of Dota 2 would be ported over to Source 2 in an update called Dota 2 Reborn. Reborn was first released to the public as an opt-in beta update that same month, and officially replaced the original client in September 2015, making it the first game to use the engine. The engine was also used for Valve's digital collectable card game Artifact, released in 2018, with a version of Source 2 created for Android and iOS to support the game on those platforms. Half-Life: Alyx, an upcoming virtual reality (VR) game by Valve, will also use Source 2.
Open source promotes universal access via an open-source or free license to a product's design or blueprint, and universal redistribution of that design or blueprint. Before the phrase open source became widely adopted, developers and producers used a variety of other terms. Open source gained hold with the rise of the Internet. The open-source software movement arose to clarify copyright, licensing, domain, and consumer issues.
A plasma sound source (PSS), otherwise called a spark gap sound source, or simply a sparker, is a means of making a very low frequency sonar pulse underwater. For each firing, electric charge is stored in a large high-voltage bank of capacitors, and then released in an arc across electrodes in the water. The underwater spark discharge produces a high-pressure plasma and vapor bubble, which expands and collapses, making a loud sound. Most of the sound produced is between 20 and 200 Hz, useful for both seismic and sonar applications.
A powerful source is intended to bring about compliance in the receiver. An example would be a police officer giving an anti-drink drive message.
In December 2010, Source and PIMCO, the world's largest fixed income manager announced their partnership of creating fixed income ETFs based on proprietary indices and range of actively managed products. Source and PIMCO launched their first two products in early January 2011 - the PIMCO Euro Enhanced Short Maturity Source ETF and the PIMCO European Advantage, the former being Europe's first actively managed ETF. The latest addition to the platform was the PIMCO US Dollar Enhanced Short Maturity Source ETF. In line with its inaugural aim, the products offered through the partnership focus on "the unmet demands", of European investors through innovation." For instance, in the current challenging environment of low returns for money market ETFs PIMCO Source Euro and US Dollar Enhanced Maturity funds aim to overcome this issue by active management. PIMCO's older US-domiciled MINT fund that is based on the same strategy has been very successful so far in attracting investor money with the fund becoming the very first actively managed ETF in the world to cross $1bn mark. The PIMCO European Advantage Government Bond Index Source ETF, though a passive tracker, addresses the fundamental issues in bond investing by replicating PIMCO's European Advantage Government Bond Index that is based on GDP-weighted methodology.
Source SDK is the software development kit for the Source engine, and contains many of the tools used by Valve to develop assets for their games. It comes with several command-line programs designed for special functions within the asset pipeline, as well as a few GUI-based programs designed for handling more complex functions. Source SDK was launched as a free standalone toolset through Steam, and required a Source game to be purchased on the same account. Since the release of Left 4 Dead in late 2008, Valve began releasing "Authoring Tools" for individual games, which constitute the same programs adapted for each game's engine build. After Team Fortress 2 became free-to-play, Source SDK was effectively made open to all Steam users. When some Source games were updated to Source 2013, the older Source SDKs were phased out. The three applications mentioned below are now included in the install of each game.
A Van de Graaff generator is an example of such a high voltage current source. It behaves as an almost constant current source because of its very high output voltage coupled with its very high output resistance and so it supplies the same few microamperes at any output voltage up to hundreds of thousands of volts (or even tens of megavolts) for large laboratory versions.
The ECR ion source makes use of the electron cyclotron resonance to ionize a plasma. Microwaves are injected into a volume at the frequency corresponding to the electron cyclotron resonance, defined by the magnetic field applied to a region inside the volume. The volume contains a low pressure gas.
An attractive source is one that the receiver can identify with, or aspire to. The message from such as source is identified with by the receiver; e.g. "slice of life" advertising, for products such as washing powder, regularly feature actors in situations that are intended to reflect the lives of the target segment.
The Source 2007 branch represented a full upgrade of the Source engine for the release of The Orange Box. An artist-driven, threaded particle system replaced previously hard-coded effects for all of the games within. An in-process tools framework was created to support it, which also supported the initial builds of Source Filmmaker. In addition, the facial animation system was made hardware-accelerated on modern video cards for "feature film and broadcast television" quality. The release of The Orange Box on multiple platforms allowed for a large code refactoring, which let the Source engine take advantage of multiple CPU cores. However, support on the PC was experimental and unstable until the release of Left 4 Dead. Multiprocessor support was later backported to Team Fortress 2 and Day of Defeat: Source. Valve created the Xbox 360 release of The Orange Box in-house, and support for the console is fully integrated into the main engine codeline. It includes asset converters, cross-platform play and Xbox Live integration. Program code can be ported from PC to Xbox 360 simply by recompiling it. The PlayStation 3 release was outsourced to Electronic Arts, and was plagued with issues throughout the process. Gabe Newell cited these issues when criticizing the console during the release of The Orange Box.
Africa Source's first camp was held from March 15 to 19, 2004 at Okahandja, Namibia. It had around 60 participants from across Africa. This event's focus was on "the practical challenges of realising F/OSS [Free/Libre and Open Source Software] in the African context, the aim was to build cooperation between Africa's most active F/OSS individuals and projects in the longer term."
Asia Source 3 gathered 150 representatives in Silang, Cavite in the Philippines from 7 to 12 November 2009 to discuss regional developments in open source. *
Many issues came up for debate at the Africa Source 2. Among them were that FLOSS is still too complicated for non-profit organisations and schools to use, and the need for translating FLOSS into African languages.
In the physical network SSR utilizes source routing. Relaying nodes opportunistically cache the traversed part of the source route of a given packet. This facilitates the collection of routing information while inhibiting polluting of the nodes' route caches with outdated information.
Source has had a website since 1997. Since 2002 this has included a growing archive of all the back issue content of the magazine. Additionally it contains two projects that are specific to the website: oral history interviews and graduate photography online. The Source oral history archive consists of lengthy interviews with photographers, curators and writers about their lives and involvement in photography. These are gradually being made available as indexed audio files sometimes up to three hours in length. Graduate photography online, running since 2007 is a large gallery of the work of graduating photography students in Ireland and the UK with each student represented by a selection of their work indexed by the universities they have attended.
Generally line source acoustic models trace sound ray bundles and calculate spreading loss along with ray bundle divergence (or convergence} from refractive phenomena. Diffraction is usually addressed by establishing secondary emitters at any points of topographic or anthropomorphic “sharpness” (such as noise barriers or building surfaces. Meteorology can be addressed in a statistical manner allowing for actual wind rose and wind speed statistics (along with thermocline data).
The Source Filmmaker (SFM) is a video capture and editing application that works from within the Source engine. Developed by Valve, the tool was originally used to create movies for Day of Defeat: Source, but is more associated with Team Fortress 2. Today, it is open for public use and downloadable via the Steam client.
The first Source Sandals were sold in 1991 under the name Shoresh (Hebrew for root, spring: שורש), at this time there were 3 models: The Biblical sandal, The Roman sandal, The Asia sandal.
