Separation Of Variables
In mathematics, separation of variables (also known as the Fourier method) is any of several methods for solving ordinary and partial differential equations, in which algebra allows one to rewrite an equation so that each of two variables occurs on a different side of the equation. Ordinary differential equations (ODE) Suppose a differential equation can be written in the form :\frac f(x) = g(x)h(f(x)) which we can write more simply by letting y = f(x): :\frac=g(x)h(y). As long as ''h''(''y'') ≠ 0, we can rearrange terms to obtain: : = g(x) \, dx, so that the two variables ''x'' and ''y'' have been separated. ''dx'' (and ''dy'') can be viewed, at a simple level, as just a convenient notation, which provides a handy mnemonic aid for assisting with manipulations. A formal definition of ''dx'' as a differential (infinitesimal) is somewhat advanced. Alternative notation Those who dislike Leibniz's notation may prefer to write this as :\frac \frac = g(x), but that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Separations (album)
''Separations'' is the third studio album by English rock band Pulp, released on 19 June 1992 by Fire Records. Release and aftermath Recorded in 1989, it was belatedly released in 1992 by the independent record label Fire, having already been released in France in 1991 on Rosebud Records. The songs on the second half of the album range between electronic synthpop and experimental acid house styles, while the first half contains songs more typical of Pulp's late 80s music. The album was reissued and remastered by Fire in 2012 along with 1983's '' It'' and 1987's ''Freaks''. This re-release took several delays as the first stated release date was 8 August 2011 while the albums finally came out on 13 February 2012. An announcement in the interim stated that the albums would be remastered with new bonus tracks to be added to the track listings as well as new artwork and liner notes from music journalist Everett True. This re-release gives an opportunity to hear "Death Comes to Town ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Separatism
Separatism is the advocacy of cultural, ethnic, tribal, religious, racial, governmental or gender separation from the larger group. As with secession, separatism conventionally refers to full political separation. Groups simply seeking greater autonomy are not separatist as such. Some discourse settings equate separatism with religious segregation, racial segregation, or sex segregation, while other discourse settings take the broader view that separation by choice may serve useful purposes and is not the same as government-enforced segregation. There is some academic debate about this definition, and in particular how it relates to secessionism, as has been discussed online. Separatist groups practice a form of identity politics, or political activity and theorizing founded in the shared experiences of the group's members. Such groups believe attempts at integration with dominant groups compromise their identity and ability to pursue greater self-determination. However, econo ...

Mutual Fund Separation Theorem
In portfolio theory, a mutual fund separation theorem, mutual fund theorem, or separation theorem is a theorem stating that, under certain conditions, any investor's optimal portfolio can be constructed by holding each of certain mutual funds in appropriate ratios, where the number of mutual funds is smaller than the number of individual assets in the portfolio. Here a mutual fund refers to any specified benchmark portfolio of the available assets. There are two advantages of having a mutual fund theorem. First, if the relevant conditions are met, it may be easier (or lower in transactions costs) for an investor to purchase a smaller number of mutual funds than to purchase a larger number of assets individually. Second, from a theoretical and empirical standpoint, if it can be assumed that the relevant conditions are indeed satisfied, then implications for the functioning of asset markets can be derived and tested. Portfolio separation in mean-variance analysis Portfolios can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Separation Theorem (other)
Separation theorem may refer to several theorems in different scientific fields. Economics * Fisher separation theorem (corporation theory) - asserts that the objective of a corporation will be the maximization of its present value, regardless of the preferences of its shareholders. *Mutual fund separation theorem (portfolio theory) states that, under certain conditions, any investor's optimal portfolio can be constructed by holding each of certain mutual funds in appropriate ratios, where the number of mutual funds is smaller than the number of individual assets in the portfolio. Mathematics * Gabbay's separation theorem (mathematical logic and computer science) states that any arbitrary temporal logic formula can be rewritten in a logically equivalent "past → future" form. *Planar separator theorem (graph theory) states that any planar graph can be split into smaller pieces by removing a small number of vertices. * Lusin's separation theorem (descriptive set theory) states t ...

Separation Process
A separation process is a method that converts a mixture or a solution (chemistry), solution of chemical substances into two or more distinct product mixtures, a scientific process of separating two or more substance in order to obtain purity. At least one product mixture from the separation is enriched in one or more of the source mixture's constituents. In some cases, a separation may fully divide the mixture into pure constituents. Separations exploit differences in chemical properties or physical properties (such as size, shape, mass, density, or chemical affinity) between the constituents of a mixture. Processes are often classified according to the particular properties they exploit to achieve separation. If no single difference can be used to accomplish the desired separation, multiple unit operation, operations can often be combined to achieve the desired end. With a few exceptions, chemical element, elements or Chemical compound, compounds exist in nature in an impure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Separation Principle
In control theory, a separation principle, more formally known as a principle of separation of estimation and control, states that under some assumptions the problem of designing an optimal feedback controller for a stochastic system can be solved by designing an optimal observer for the state of the system, which feeds into an optimal deterministic controller for the system. Thus the problem can be broken into two separate parts, which facilitates the design. The first instance of such a principle is in the setting of deterministic linear systems, namely that if a stable observer and a stable state feedback are designed for a linear time-invariant system (LTI system hereafter), then the combined observer and feedback is stable. The separation principle does not hold in general for nonlinear systems. Another instance of the separation principle arises in the setting of linear stochastic systems, namely that state estimation (possibly nonlinear) together with an optimal state feedba ...

Separation Of Concerns
In computer science, separation of concerns is a design principle for separating a computer program into distinct sections. Each section addresses a separate '' concern'', a set of information that affects the code of a computer program. A concern can be as general as "the details of the hardware for an application", or as specific as "the name of which class to instantiate". A program that embodies SoC well is called a modular program. Modularity, and hence separation of concerns, is achieved by encapsulating information inside a section of code that has a well-defined interface. Encapsulation is a means of information hiding. Layered designs in information systems are another embodiment of separation of concerns (e.g., presentation layer, business logic layer, data access layer, persistence layer). Separation of concerns results in more degrees of freedom for some aspect of the program's design, deployment, or usage. Common among these is increased freedom for simplification and ...

Separation Axiom
In topology and related fields of mathematics, there are several restrictions that one often makes on the kinds of topological spaces that one wishes to consider. Some of these restrictions are given by the separation axioms. These are sometimes called ''Tychonoff separation axioms'', after Andrey Tychonoff. The separation axioms are not fundamental axioms like those of set theory, but rather defining properties which may be specified to distinguish certain types of topological spaces. The separation axioms are denoted with the letter "T" after the German ''Trennungsaxiom ("''separation axiom"), and increasing numerical subscripts denote stronger and stronger properties. The precise definitions of the separation axioms has varied over time. Especially in older literature, different authors might have different definitions of each condition. Preliminary definitions Before we define the separation axioms themselves, we give concrete meaning to the concept of separated sets (a ...

Separated Sets
In topology and related branches of mathematics, separated sets are pairs of subsets of a given topological space that are related to each other in a certain way: roughly speaking, neither overlapping nor touching. The notion of when two sets are separated or not is important both to the notion of connected spaces (and their connected components) as well as to the separation axioms for topological spaces. Separated sets should not be confused with separated spaces (defined below), which are somewhat related but different. Separable spaces are again a completely different topological concept. Definitions There are various ways in which two subsets of a topological space ''X'' can be considered to be separated. * ''A'' and ''B'' are disjoint if their intersection is the empty set. This property has nothing to do with topology as such, but only set theory. It is included here because it is the weakest in the sequence of different notions. ** ''A'' and ''B'' are separated in ' ...

Intertemporal Portfolio Choice
Intertemporal portfolio choice is the process of allocating one's investable wealth to various asset In financial accountancy, financial accounting, an asset is any resource owned or controlled by a business or an economic entity. It is anything (tangible or intangible) that can be used to produce positive economic value. Assets represent value ...s, especially financial assets, repeatedly over time, in such a way as to optimization, optimize some criterion. The set of asset proportions at any time defines a Portfolio (finance), portfolio. Since the returns on almost all assets are not fully predictable, the criterion has to take financial risk into account. Typically the criterion is the expected value of some concave function of the value of the portfolio after a certain number of time periods—that is, the expected utility of final wealth. Alternatively, it may be a function of the various levels of goods and services Consumption (economics), consumption that are attained ...
