Factorization Norms and Hereditary Discrepancy
The ellipsoid-infinity norm of a real m × n matrix A, denoted by ‖A‖E∞, is the minimum `∞ norm of an 0-centered ellipsoid E ⊆ R that contains all column vectors of A. This quantity, introduced by the second author and Talwar in 2013, is polynomial-time computable and approximates the hereditary discrepancy herdiscA as follows: ‖A‖E∞/O(logm) ≤ herdiscA ≤ ‖A‖E∞ ·O( √ logm). Here we show that both...
متن کاملVoting and different ranking orders in DEA
Data Envelopment Analysis (DEA) technique now widely use for efficiency evaluation of a set of Decision Making Units (DMUs). As regards of the necessity for ranking efficient units different DEA models presented each of which has advantages and rank efficient units from special aspects. Note that all the existing ranking models have disadvantages, as well and there is not a model in which all t...
متن کاملStatistics Orders and Determinant Factors in Tariffs in Iran
Import tariffs are set based on the following factors: terms of trade, government revenue, trade agreements, trade protection, and political economy. This study attempts to evaluate the explanatory power of these factors in influencing the import tariffs in Iran. The data sources that have been used in this study are: Iran’s custom, import and export regulation book, survey of industrial plants...
متن کاملHereditary benign Telangiectasia: Report of 6 cases in a family
Hereditary benign telangiectasia is an uncommon idiopathic skin disorder characterized by generalized telangiectases and angiomatous lesions of the skin. The diagnosis should be suspected in patients with such cutaneous lesions, positive family history, no associated bleeding problems, and no mucosal involvement. We present six cases of hereditary benign telangiectasia in three generations of o...
متن کاملOn orders induced by implications
In this paper, the orders induced by the residual implications obtained from uninorms are investigated. A necessary and sufficient condition is presented so that the ordinal sum of fuzzy implications satisfies the law of importation with a t-norm $T$. Some relationships between the orders induced by an ordinal sum implication and its summands are determined. The algebraic structures obtained fr...
