Is Hesaabdaaree an Adequate Equivalent for Accounting?
Some of the difficulties and misunderstandings that happen in accounting theory, practice, regulation and education are grounded in language and linguistics. As an illustration of this the Persian equivalent of 'accounting' is linguistically analysed to reveal how a mistranslation may cause difficulties in understanding and improving Iranian Accounting. This paper shows how Hesaabdaaree is not ...
متن کاملMedian Filtering is Equivalent to Sorting
This work shows that the following problems are equivalent, both in theory and in practice: • median filtering : given an n-element vector, compute the sliding window median with window size k, • piecewise sorting : given an n-element vector, divide it in n/k blocks of length k and sort each block. By prior work, median filtering is known to be at least as hard as piecewise sorting: with a sing...
متن کاملConstraint Problems: Computability Is Equivalent to Continuity
In many practical situations, we would like to compute the set of all possible values that satisfy given constraints. It is known that even for computable (constructive) constraints, computing such set is not always algorithmically possible. One reason for this algorithmic impossibility is that sometimes, the dependence of the desired set on the parameters of the problem is not continuous, whil...
متن کاملNumber of Variables Is Equivalent to Space
We prove that the set of properties describable by a uniform sequence of rst-order sentences using at most k + 1 distinct variables is exactly equal to the set of properties checkable by a Turing machine in DSPACEn k ] (where n is the size of the universe). This set is also equal to the set of properties describable using an iterative deenition for a nite set of relations of arity k. This is a ...
متن کاملExact PT-Symmetry Is Equivalent to Hermiticity
We show that a quantum system possessing an exact antilinear symmetry, in particular PT -symmetry, is equivalent to a quantum system having a Hermitian Hamiltonian. We construct the unitary operator relating an arbitrary non-Hermitian Hamiltonian with exact PT -symmetry to a Hermitian Hamiltonian. We apply our general results to PT symmetry in finite-dimensions and give the explicit form of the...
