چکیده
Motivated by the Arhangel?skii ?s-Lindel?f cardinal function? definition, Kocinac, Konca, Bonanzinga, Maesano and Singh defined studied set covering properties. In this paper, we study some versions of compact-type properties give partial solution to a problem posed in [11].

A ~e on some empirical properties of the Mandelbrot Set
In this note we inspect the kind of patterns produced by the quadratic iteration used to generate the Mandelbrot set. A very simple relation involving the Fibonacci numbers can be found between the relative positions of the disks which form the Mandelbrot set and the number of attractors of the iteration. Using this insight the concept of escape time can be generalized to points inside and not ...
متن کاملOn Some New Properties of Soft Set Operations
In this paper, we establish some new results related to distributive properties of AND ( ) and OR ( ) -operations with respect to operations of union, restricted union restricted intersection, extended intersection and restricted difference on soft sets, and provide some illustrative examples.
متن کاملSome properties of equivalence soft set relations
The soft set theory is a new mathematical tool for dealing with uncertainties that is free from the difficulties that have troubled the usual theoretical approaches. Babitha and Sunil [Soft set relations and function, Computers and Mathematics with Applications 60 (2010) 1840–1849] introduced the notion of soft set relations as a soft subset of the Cartesian product of soft sets and discussed m...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولSome Bijections on Set Partitions
We study three similar bijections on set partitions. The first is an involution defined by Kasraoui and Zeng which proves the symmetry of the distribution of crossings and nestings. We show that a stronger result can be deduced. The second gives a bijective proof of the equivalence of two statistics with a q-Stirling distribution. The third proves the equivalence of a multivariate block size di...
