79,787 | Algodoo () is a physics-based 2D sandbox freeware from Algoryx Simulation AB (known simply as Algoryx) as the successor to the popular physics application Phun. It was released on September 1, 2009 and is presented as a learning tool, an open ended computer game, an animation tool, and an engineering tool. The software... | Algodoo | 0.800004 |
79,788 | In the next step, the declarative query is translated into a logical query plan. A query plan is a directed graph where the nodes are operators and the edges describe the processing flow. Each operator in the query plan encapsulates the semantic of a specific operation, such as filtering or aggregation. In DSMSs that p... | Data Stream Management System | 0.800003 |
79,789 | Its unusual chemistry has prompted further speculation that Hypatia may predate the formation of the Solar System.In 2018 Georgy Belyanin of the University of Johannesburg and colleagues found compounds including polyaromatic hydrocarbons and silicon carbide associated with a previously-unknown nickel phosphide compoun... | Hypatia (stone) | 0.800003 |
79,790 | Cloud computing provides large-scale computing thanks to its ability to provide the needed CPU and storage resources to the user with complete transparency. This makes cloud computing particularly suited to support different types of applications that require large-scale distributed processing. This data-intensive comp... | Distributed file system for cloud | 0.800003 |
79,791 | In molecular biology, Small Cajal body specific RNA 13 (also known as scaRNA13 or U93) is a small nucleolar RNA found in Cajal bodies and believed to be involved in the pseudouridylation of U2 and U5 spliceosomal RNA. scaRNAs are a specific class of small nucleolar RNAs that localise to the Cajal bodies and guide the m... | Small Cajal body specific RNA 13 | 0.800002 |
79,792 | The Archimedean spiral, studied by Archimedes as a method to trisect an angle and square the circle. The spiric sections, sections of tori studied by Perseus as sections of cones had been studied by Apollonius.A fundamental advance in the theory of curves was the introduction of analytic geometry by René Descartes in t... | Curved lines | 0.800002 |
79,793 | The lemma can be applied to give a covering theorem in Rn. Specifically (Stein 1993, Lemma X.2.1), if Ej is a collection of Lebesgue measurable subsets of a compact set in Rn such that then there is a sequence Fj of translates such that apart from a set of measure zero. | Borel–Cantelli lemma | 0.800002 |
79,794 | In 1910, he derived the Planck radiation formula using a method which Max Planck agreed was simpler than his own. In 1911, when Albert Einstein took an appointment as a professor at Prague, Bohemia, Debye took his old professorship at the University of Zurich, Switzerland. This was followed by moves to Utrecht in 1912,... | Peter Debye | 0.800002 |
79,795 | Before the 1960s (and in some cases decades after), many eventual materials science departments were metallurgy or ceramics engineering departments, reflecting the 19th and early 20th-century emphasis on metals and ceramics. The growth of materials science in the United States was catalyzed in part by the Advanced Rese... | Engineering material | 0.800001 |
79,796 | Selling the certificates is another way for renewable producers to supplement their revenues.Certificate prices fluctuate based on overall energy demand and competition among renewable producers. If the amount of renewable energy produced exceeds the required amount, certificate prices may crash, like with carbon tradi... | Feed-in Tariff | 0.800001 |
79,797 | Greenhouse Solutions with Sustainable Energy is a 2007 book by Australian academic Mark Diesendorf.

79,798 | A reference dimension is a dimension on an engineering drawing provided for information only. Reference dimensions are provided for a variety of reasons and are often an accumulation of other dimensions that are defined elsewhere (e.g. on the drawing or other related documentation). These dimensions may also be used fo... | Reference dimension | 0.800001 |
79,799 | This theorem has applications to Ramsey theory, specifically graph Ramsey theory. Using this theorem, a relationship between the graph Ramsey numbers and the extremal numbers can be shown (see Graham-Rothschild-Spencer for the details). | Symmetric hypergraph theorem | 0.800001 |
