A simple method for determining an overall heat transfer coefficient that is useful to find the heat transfer between simple elements such as walls in buildings or across heat exchangers is shown below. Note that this method only accounts for conduction within materials, it does not take into account heat ... | wikipedia |
wiki_6147_chunk_10 | Supramolecular chemistry | Both and values can be determined at a given temperature, , by means of Isothermal titration calorimetry. For an example, see Sessler. et.al. In that example a macrocyclic ring with 4 protonated nitrogen atoms encapsulates a chloride anion; illustrations of ITC data and a titration curve are reproduced in Steed&Atwoo... | wikipedia |
wiki_39272_chunk_1 | Schur algebra | Construction
The Schur algebra can be defined for any commutative ring and integers . Consider the algebra of polynomials (with coefficients in ) in commuting variables , 1 ≤ i, j ≤ . Denote by the homogeneous polynomials of degree . Elements of are k-linear combinations of monomials formed by multiplying togeth... | wikipedia |
wiki_35759_chunk_20 | Original North American area codes | In this table, the assignments of the nine area codes to the Canadian provinces are highlighted by a blue background. The red fields are the NPAs that hosted the Regional Centers for toll-switching established in the General Toll Switching Plan of 1929: New York City (212), Los Angeles (213), Dallas (214), Chicago (312... | wikipedia |
wiki_26794_chunk_1 | Molecular graph | In some important cases (topological index calculation etc.) the following classical definition is sufficient: a molecular graph is a connected, undirected graph which admits a one-to-one correspondence with the structural formula of a chemical compound in which the vertices of the graph correspond to atoms of the mole... | wikipedia |
wiki_8143_chunk_1 | Topological graph theory | Embedding a graph in a surface means that we want to draw the graph on a surface, a sphere for example, without two edges intersecting. A basic embedding problem often presented as a mathematical puzzle is the three utilities problem. Other applications can be found in printing electronic circuits where the aim is to p... | wikipedia |
wiki_33320_chunk_1 | Michael R. Powers | Research
Powers has published numerous scholarly articles on a variety of risk-related topics, with particular focus on issues of government regulation and public policy. His major research contributions include: the introduction of intertemporal discounting into collective risk theory (actuarial ruin theory); the deri... | wikipedia |
wiki_30830_chunk_19 | Data & Analysis Center for Software | DACS Technical Area Tasks
As is the case with all DTIC managed IACs, DACS serves as a contract vehicle that enables DoD components to acquire technical services from commercial providers (Defense contractors, small businesses, etc.) and academic institutions without having to engage in a formal competitive bid process.... | wikipedia |
wiki_17538_chunk_2 | SmartCode | In the discussion of Smart Growth as an alternative to urban sprawl, one key aspect often overlooked is the currently prevailing system of community development codes and standards that by design, whether intentionally or not, have promoted subdivisions and strip malls. To change these community settlement patterns to... | wikipedia |
wiki_11323_chunk_5 | Dynamic covalent chemistry | The concept of a thermodynamic template is demonstrated in scheme 1. A thermodynamic template is a reagent that can stabilize the form of one product over others by lowering its Gibb's free energy (ΔG°) in relation to other products. cyclophane C2 can be prepared by the irreversible highly diluted reaction of a diol wi... | wikipedia |
wiki_1681_chunk_18 | List of unsolved problems in physics | Plasma physics
Plasma physics and fusion power: Fusion energy may potentially provide power from abundant resource (e.g. hydrogen) without the type of radioactive waste that fission energy currently produces. However, can ionized gases (plasma) be confined long enough and at a high enough temperature to create fusion... | wikipedia |
wiki_20128_chunk_1 | CRC Handbook of Chemistry and Physics | As late as the 1962–1963 edition (3604 pages) the Handbook contained myriad information for every branch of science and engineering. Sections in that edition include: Mathematics, Properties and Physical Constants, Chemical Tables, Properties of Matter, Heat, Hygrometric and Barometric Tables, Sound, Quantities and Un... | wikipedia |
wiki_23194_chunk_24 | Map database management | Identifiers assigned to entries in a table are 16-bit integers and therefore have a range of 65536 values. This is too few to cover the world, so separate tables are formulated for each country or region of a country. For a given metropolitan region, only intersections along freeways, arterials and some major roads a... | wikipedia |
wiki_2784_chunk_19 | Assignment (computer science) | Parallel assignment
Some programming languages, such as APL, Common Lisp, Go, JavaScript (since 1.7), PHP, Maple, Lua, occam 2, Perl, Python, REBOL, Ruby, and PowerShell allow several variables to be assigned in parallel, with syntax like: a, b := 0, 1 | wikipedia |
