Background: Hundreds of patient education materials i.e. pamphlets are annually published in healthcare systems following their design, correction, and revision. Aim: to design and evaluate patient education pamphlets based on readability indexes and their comparison with literacy level in society. Method: The average literacy level among 500 patients admitted to two training hospitals in Bojnu...

For any natural number n we define f(n) to be the minimum number with the following property. Given any arrangement A(L) of n blue lines in the real projective plane one can find f(n) red lines different from the blue lines such that any edge in the arrangement A(L) is crossed by a red line. We define h(n) to be the minimum number with the following property. Given any arrangement A(L) of n blu...

An ongoing discussion in IS research and practice emphasizes that divergent expectations of clients and vendors seem to contribute to outsourcing failures. Research in IS outsourcing has thus increasingly turned its attention to the role of relationship management between client and vendor. So far, studies have focused on addressing relationship factors in general, not taking different outsourc...

This expository article outlines the construction of De ConciniProcesi arrangement models and describes recent progress in understanding their significance from the algebraic, geometric, and combinatorial point of view. Throughout the exposition, a strong emphasis is given to combinatorial and discrete geometric data that lies at the core of the construction.

In this paper we study two problems concerning the arrangement of a given finite point set in the unit cube. We give a satisfying solution for both of these problems in dimension one and show their intimate relation. 2010 Mathematics Subject Classification: 11K06, 11K38.

Let K be a number field containing, for some prime `, the `-th roots of unity. Let L be a Kummer extension of degree ` of K characterized by its modulus m and its norm group. Let Km be the compositum of degree ` extensions of K of conductor dividing m. Using the vector-space structure of Gal(Km/K), we suggest a modification of the rnfkummer function of PARI/GP which brings the complexity of the...

The paper is focused on issues of processing of non-ferrous metals in practice, namely on Mg-Al-Zn based on magnesium alloys with graded Al contents. It is well known that forming of these alloys is difficult since this feature is caused by their crystallographic arrangement. Nevertheless, application of appropriate methods of forming, such as e.g. some of SPD processes, makes it possible to ac...

We define the decision problem data arrangement, which involves arranging the vertices of a graph G at the leaves of a d-ary tree so that a weighted sum of the distances between pairs of vertices measured with respect to the tree topology is at most a given value. We show that data arrangement is strongly NP-complete for any fixed d ≥ 2 and explain the connection between data arrangement and ar...

1 2 Preface This book presents work in two of the most popular areas of geometric computation: Robust Geometric Computing and Optimal Visibility Coverage. Both areas have been extensively researched in recent years and attracted the attention of many researchers and developers in both the academic and the industrial worlds. The work we present here aims to contribute to this effort by providing...
