In network code setting, a constant dimension code is a set of k-dimensional subspaces of F nq . If F_q n is a nondegenerated symlectic vector space with bilinear form f, an isotropic subspace U of F n q is a subspace that for all x, y ∈ U, f(x, y) = 0. We introduce isotropic subspace codes simply as a set of isotropic subspaces and show how the isotropic property use in decoding process, then...

Potency tests, known as quantitative tests, are designed to determine how much of the active drug is in the sample. Stability tests are used to determine a beyond-use date for a preparation. Employing the proper method to determine potency or stability is key to understanding the difference between potency testing and stability testing. Methods of determining potency may or may not be stability...

Potency tests are designed to determine how much of an active drug is in a sample. Stability tests are used to determine an expiration date of a product or a beyond-use date of a preparation. Being able to employ the proper method to determine potency or stability is the key to understanding the difference between potency testing versus stability testing. In order to determine potency, a method...

This paper introduces the impact of negative online reviews on consumers’ purchase intention from the dimension of the product information, namely tangible dimension and intangible dimension. By using the experimental method, this study analyzes the impact of product information, dimension of negative online reviews on purchase intention and the moderating role of product type. Results suggest ...

The VC-dimension plays an important role for the algorithmic problem of guarding art galleries efficiently. We prove that inside a simple polygon at most 5 points can be shattered by L1-visibility polygons and give an example where 5 points are shattered. The VCdimension is exactly 5. The proof idea for the upper bound is different from previous approaches.

This paper introduces a method for modification of the formula of the fractal box counting dimension. The method is based on the utilization of the probability distribution formula in the fractal box count. The purpose of this method is to use it for the discrimination of oil spill areas from the surrounding features e.g., sea surface and look-alikes in RADARSAT-1 SAR data. The result shows tha...

A first-order expansion of the R-vector space structure on R does not define every compact subset of every Rn if and only if topological and Hausdorff dimension coincide on all closed definable sets. Equivalently, if A ⊆ Rk is closed and the Hausdorff dimension of A exceeds the topological dimension of A, then every compact subset of every Rn can be constructed from A using finitely many boolea...

This paper deals with three resolving parameters: the metric dimension, the upper dimension and the resolving number. We first answer a question raised by Chartrand and Zhang asking for a characterization of the graphswith equalmetric dimension and resolving number. We also solve in the affirmative a conjecture posed by Chartrand, Poisson and Zhang about the realization of the metric dimension ...

phenomena in two dimensions. I spent most of the academic years 2013-2015 in Bonn, Germany (at the Max-Planck Institut and then the Hausdorff Center). In general, the Hausdorff dimension of a product is at least the sum of the dimensions of the two spaces. Does equality hold if one space is Euclidian? So let be. I find this discussion in Wikipedia very good: Fractal dimension Imagine a particul...
