  • Designing of Parking Spaces on Parking Taking into Account the Parameters of Design Vehicles

    Publication

    - Computation - Year 2020

    Nowadays, in all cities, there is an acute problem of a lack of parking spaces. The number of vehicles is constantly increasing not only in big cities and megacities, but also in small towns of the country, and there are not enough parking places—the pace of solving the problem is several times slower than the growth rate of transport among citizens. The paper is dedicated to the determination of an optimal size of a parking place...

  • The UK's banking system as financial hub for Islamic banking

    Publication

    - International Journal of Behavioural Accounting and Finance - Year 2014

    This paper examines the phenomenon of London as "the Islamic banking hub". It contends that London has become not only an international centre for Islamic finance, but also that there is big interest and demand for Islamic banking products. The authors are also positive that Islamic banking may be a certain solution for the problems that Europe has been suffering since 2007 when the global debt crisis started. Our intention is...

    - JOURNAL OF COMBINATORIAL OPTIMIZATION - Year 2022

    Given a graph G = (V(G), E(G)), the size of a minimum dominating set, minimum paired dominating set, and a minimum total dominating set of a graph G are denoted by γ (G), γpr(G), and γt(G), respectively. For a positive integer k, a k-packing in G is a set S ⊆ V(G) such that for every pair of distinct vertices u and v in S, the distance between u and v is at least k + 1. The k-packing number is the order of a largest kpacking and...

  • Packing [1,Delta]-factors in graphs of small degree

    Publication

    - JOURNAL OF COMBINATORIAL OPTIMIZATION - Year 2007

    Rozważano problem znalezienia w grafie zadanej liczby k krawędziowo rozłącznych [1,Delta]-faktorów, gdzie Delta oznacza stopień grafu. Problem ten można rozwiązać w czasie liniowym dla k=2, jest on jednak NP-trudny dla każdego k>=3. Pokazano, że wariant minimalizacjny problemu dla k=2 jest NP-trudny dla grafów planarnych podkubicznych, jednak w ogólności istnieje algorytm (42 Delta - 30) / (35 Delta - 21) - aproksymacyjny.

    We present an algorithm that computes a function that assigns consecutive integers to trees recognized by a deterministic, acyclic, finite-state, bottom-up tree automaton. Such function is called minimal perfect hashing. It can be used to identify trees recognized by the automaton. Its value may be seen as an index in some other data structures. We also present an algorithm for inverted hashing.Przedstawiamy algorytm, który oblicza...

  • On-line ranking of split graphs

    Publication

    - DISCRETE MATHEMATICS AND THEORETICAL COMPUTER SCIENCE - Year 2013

    A vertex ranking of a graph G is an assignment of positive integers (colors) to the vertices of G such that each path connecting two vertices of the same color contains a vertex of a higher color. Our main goal is to find a vertex ranking using as few colors as possible. Considering on-line algorithms for vertex ranking of split graphs, we prove that the worst case ratio of the number of colors used by any on-line ranking algorithm...

    Modern foot bridges are more and more sensitive to variable load created by moving pedestrians. These are several reasons for that. Quickly growing up road infrastructure forces us to build foot bridges just to reconnect one piece of land, separated now by the new road or railway. These bridges are lightweight because the only live load acting on them comes from pedestrians.The paper focuses on the definition of human induces dynamic...
