It is common convention to use greek indices when writing expressions involving tensors in Minkowski space, while Latin indices are reserved for Euclidean space. Well-formulated expressions are constrained by the rules of Einstein summation : any index may appear at most twice and furthermore a raised index must contract with a lowered index.
All superlative indices produce similar results and are generally the favored formulas for calculating price indices. [14] A superlative index is defined technically as "an index that is exact for a flexible functional form that can provide a second-order approximation to other twice-differentiable functions around the same point."
These new rules required that 100% of the assessment in a GCSE be submitted in the final examination series, at the same time as applying for certification of the full qualification. [ 31 ] [ 32 ] [ 33 ] The examination boards complied by modifying the syllabi of the remaining GCSE qualifications to remove modular components.
GCSE Bitesize was launched in January 1998, covering seven subjects. For each subject, a one- or two-hour long TV programme would be broadcast overnight in the BBC Learning Zone block, and supporting material was available in books and on the BBC website. At the time, only around 9% of UK households had access to the internet at home.
In mathematics, especially the usage of linear algebra in mathematical physics and differential geometry, Einstein notation (also known as the Einstein summation convention or Einstein summation notation) is a notational convention that implies summation over a set of indexed terms in a formula, thus achieving brevity.
A rare “stay at home” warning has been issued for parts of the United Kingdom and Ireland as a severe storm lashes the region, bringing dangerous 100mph (160 kmh) winds and unleashing travel ...
A judge pressed the Justice Department on a Trump executive order directing the military to stop using preferred pronouns and argued there was no link between pronouns and military readiness.
Sample of a well maintained data [clarification needed]. In statistics and research design, an index is a composite statistic – a measure of changes in a representative group of individual data points, or in other words, a compound measure that aggregates multiple indicators.
