Exaction
An exaction is a concept in US real property law where a condition for development is imposed on a parcel of land that requires the developer to mitigate anticipated negative impacts of the development. The rationale for imposing the exaction is to offset the costs, defined broadly in economic terms, of the development to the municipality. Exactions are similar to impact fees, which are direct payments to local governments instead of conditions on development. Exactions and takings The Supreme Court of the United States has identified several criteria for identifying when an exaction becomes a taking that requires compensation under the Fifth Amendment. Essential nexus In ''Nollan v. California Coastal Commission'', the court ruled that an exaction is legitimate if it shares an "essential nexus" with the reasons that would allow rejection of the permit altogether. In ''Nollan'' the court required compensation for a public easement over the dry sand area of the beach as a conditio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Exact Editions
Exact Editions is an integrated content management platform for magazine and book publishers. It was launched in 2005 by Adam Hodgkin, Daryl Rayner and Tim Bruce. The platform expanded from a web-based subscription service into developing branded iOS apps for Apple’s Newsstand. These use the freemium model, offering subscriptions via an in-app purchase. They allow users to sync issues for offline use, share app content via social media and email, and bookmark pages to return to. The platform offers subscriptions to individuals and to institutions, as well as several titles in French and Spanish. In 2009 the company launched an Android app called ‘Exactly’, which offers access to all titles. In 2012, they began offering publishers the additional option to offer apps on the Kindle Fire through the Amazon Appstore. In 2012, Exact Editions launched its first complete digital archive for ''Gramophone'' magazine, offering subscribers access to 90 years' worth of back issues ( ...

Exact Differential
In multivariate calculus, a differential or differential form is said to be exact or perfect (''exact differential''), as contrasted with an inexact differential, if it is equal to the general differential dQ for some differentiable function Q in an orthogonal coordinate system. An exact differential is sometimes also called a ''total differential'', or a ''full differential'', or, in the study of differential geometry, it is termed an exact form. The integral of an exact differential over any integral path is path-independent, and this fact is used to identify state functions in thermodynamics. Overview Definition Even if we work in three dimensions here, the definitions of exact differentials for other dimensions are structurally similar to the three dimensional definition. In three dimensions, a form of the type :A(x,y,z) \,dx + B(x,y,z) \,dy + C(x,y,z) \,dz is called a differential form. This form is called ''exact'' on an open domain D \subset \mathbb^3 in spac ...

Exact Algorithm
In computer science and operations research, exact algorithms are algorithms that always solve an optimization problem to optimality. Unless P = NP, an exact algorithm for an NP-hard optimization problem cannot run in worst-case polynomial time. There has been extensive research on finding exact algorithms whose running time is exponential with a low base. See also * Approximation-preserving reduction * APX is the class of problems with some constant-factor approximation algorithm * Heuristic algorithm In mathematical optimization and computer science, heuristic (from Greek εὑρίσκω "I find, discover") is a technique designed for solving a problem more quickly when classic methods are too slow for finding an approximate solution, or whe ... * PTAS - a type of approximation algorithm that takes the approximation ratio as a parameter References {{reflist Computational complexity theory Optimization algorithms and methods ...

Exact Coloring
In graph theory, an exact coloring is a (proper) vertex coloring in which every pair of colors appears on exactly one pair of adjacent vertices. That is, it is a partition of the vertices of the graph into disjoint independent sets such that, for each pair of distinct independent sets in the partition, there is exactly one edge with endpoints in each set... Complete graphs, detachments, and Euler tours Every ''n''-vertex complete graph ''K''''n'' has an exact coloring with ''n'' colors, obtained by giving each vertex a distinct color. Every graph with an ''n''-color exact coloring may be obtained as a ''detachment'' of a complete graph, a graph obtained from the complete graph by splitting each vertex into an independent set and reconnecting each edge incident to the vertex to exactly one of the members of the corresponding independent set. When ''k'' is an odd number, A path or cycle with \tbinom edges has an exact coloring, obtained by forming an exact coloring of the complete ...

Exact Couple
In mathematics, an exact couple, due to , is a general source of spectral sequences. It is common especially in algebraic topology; for example, Serre spectral sequence can be constructed by first constructing an exact couple. For the definition of an exact couple and the construction of a spectral sequence from it (which is immediate), see . For a basic example, see Bockstein spectral sequence. The present article covers additional materials. Exact couple of a filtered complex Let ''R'' be a ring, which is fixed throughout the discussion. Note if ''R'' is \Z, then modules over ''R'' are the same thing as abelian groups. Each filtered chain complex of modules determines an exact couple, which in turn determines a spectral sequence, as follows. Let ''C'' be a chain complex graded by integers and suppose it is given an increasing filtration: for each integer ''p'', there is an inclusion of complexes: :F_ C \subset F_p C. From the filtration one can form the associated graded comple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exact Sequence
An exact sequence is a sequence of morphisms between objects (for example, groups, rings, modules, and, more generally, objects of an abelian category) such that the image of one morphism equals the kernel of the next. Definition In the context of group theory, a sequence :G_0\;\xrightarrow\; G_1 \;\xrightarrow\; G_2 \;\xrightarrow\; \cdots \;\xrightarrow\; G_n of groups and group homomorphisms is said to be exact at G_i if \operatorname(f_i)=\ker(f_). The sequence is called exact if it is exact at each G_i for all 1\leq i |
Exact Functor
In mathematics, particularly homological algebra, an exact functor is a functor that preserves short exact sequences. Exact functors are convenient for algebraic calculations because they can be directly applied to presentations of objects. Much of the work in homological algebra is designed to cope with functors that ''fail'' to be exact, but in ways that can still be controlled. Definitions Let P and Q be abelian categories, and let be a covariant additive functor (so that, in particular, ''F''(0) = 0). We say that ''F'' is an exact functor if whenever :0 \to A\ \stackrel \ B\ \stackrel \ C \to 0 is a short exact sequence in P then :0 \to F(A) \ \stackrel \ F(B)\ \stackrel \ F(C) \to 0 is a short exact sequence in Q. (The maps are often omitted and implied, and one says: "if 0→''A''→''B''→''C''→0 is exact, then 0→''F''(''A'')→''F''(''B'')→''F''(''C'')→0 is also exact".) Further, we say that ''F'' is *left-exact if whenever 0→''A''→''B''→' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
