Revolving Credit Facility
Revolving credit is a type of credit that does not have a fixed number of payments, in contrast to installment credit. Credit cards are an example of revolving credit used by consumers. Corporate revolving credit facilities are typically used to provide liquidity for a company's day-to-day operations. They were first introduced by the Strawbridge and Clothier Department Store. It is an arrangement which allows for the loan amount to be withdrawn, repaid, and redrawn again in any manner and any number of times, until the arrangement expires. Credit card loans and overdrafts are revolving loans, also called evergreen loan. Typical characteristics * The borrower may use or withdraw funds up to a pre-approved credit limit. * The amount of available credit decreases and increases as funds are borrowed and then repaid. * The credit may be used repeatedly. * The borrower makes payments based only on the amount used or withdrawn, plus interest. * The borrower may repay over time (subjec ...

RCF Audio
RCF S.p.A. (formerly Radio Cine Forniture - R.C.F. S.r.l.) is a widely recognized Italian manufacturer of high performance audio products including power amplifiers, loudspeakers, digital mixers and digital signal processors (DSP). History RCF is an Italian audio products manufacturer founded in 1949 in Reggio Emilia, Italy. The first products sold were microphones and electroacoustic transducers (loudspeakers). In the late ’60s, concert sound was going electric, and many loudspeaker pioneers were searching for high-powered devices to use in their designs. RCF was one of the first European OEM suppliers for international brands, thanks to the experience built on high power transducers. After a few years, thanks to the in-depth know-how in loudspeaker technology, RCF began to develop and produce sound reinforcement systems under the same brand. The introduction of the ART Series, in 1996, has established RCF among the few global manufacturers of active loudspeakers. The TT+ ...

Row Canonical Form
In linear algebra, a matrix is in row echelon form if it can be obtained as the result of Gaussian elimination. Every matrix can be put in row echelon form by applying a sequence of elementary row operations. The term ''echelon'' comes from the French ''échelon'' ("level" or step of a ladder), and refers to the fact that the nonzero entries of a matrix in row echelon form look like an inverted staircase. For square matrices, an upper triangular matrix with nonzero entries on the diagonal is in row echelon form, and a matrix in row echelon form is (weakly) upper triangular. Thus, the row echelon form can be viewed as a generalization of upper triangular form for rectangular matrices. A matrix is in reduced row echelon form if it is in row echelon form, with the additional property that the first nonzero entry of each row is equal to 1 and is the only nonzero entry of its column. The reduced row echelon form of a matrix is unique and does not depend on the sequence of elementary ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Real Closed Field
In mathematics, a real closed field is a field F that has the same first-order properties as the field of real numbers. Some examples are the field of real numbers, the field of real algebraic numbers, and the field of hyperreal numbers. Definition A real closed field is a field ''F'' in which any of the following equivalent conditions is true: #''F'' is elementarily equivalent to the real numbers. In other words, it has the same first-order properties as the reals: any sentence in the first-order language of fields is true in ''F'' if and only if it is true in the reals. #There is a total order on ''F'' making it an ordered field such that, in this ordering, every positive element of ''F'' has a square root in ''F'' and any polynomial of odd degree with coefficients in ''F'' has at least one root in ''F''. #''F'' is a formally real field such that every polynomial of odd degree with coefficients in ''F'' has at least one root in ''F'', and for every element ''a'' o ...
