  • Dynamic ranking of cloud providers

    Publikacja

    - Rok 2012

    The paper focuses on how to create an effective dynamic ranking service for IaaS,PaaS and SaaS cloud providers. It considers building of a quality model for thispurpose along with definition of quality measurement procedures. The paper discussesseveral techniques known from already existing price comparison engines that couldbe modified and adopted for comparison of cloud providers. Furthermore, a tech-nique for filtering measured...

  • An Evaluation Engine for Dynamic Ranking of Cloud Providers

    Publikacja

    - Informatica - Rok 2013

    The paper focuses on creation of an effective dynamic ranking service for IaaS, PaaS and SaaS cloud providers. It considers building a quality model for this purpose along with definition of quality measure- ment procedures. The paper discusses several techniques known from already existing price comparison engines that could be modified and adopted for comparison of cloud providers. A technique for filtering measured data is proposed,...

  • Ranking of ecotoxisity tests for underground water assessment using the Hasse diagram technique

    Publikacja

    - CHEMOSPHERE - Rok 2014

    The present study deals with the novel application of the Hasse diagram technique (HDT) for the specific ranking of ecotoxicity tests capable of assessment of underground water quality. The area studied is a multi-municipal landfill in the northern Poland. The monitoring network of the landfill constitutes of 27 piezometers for underground water monitoring and two observation points at surface water courses. After sampling, chemical...

  • A distributed system for conducting chess games in parallel

    This paper proposes a distributed and scalable cloud based system designed to play chess games in parallel. Games can be played between chess engines alone or between clusters created by combined chess engines. The system has a built-in mechanism that compares engines, based on Elo ranking which finally presents the strength of each tested approach. If an approach needs more computational power, the design of the system allows...

  • Integration of cloud-based services into distributed workflow systems: challenges and solutions

    The paper introduces the challenges in modern workflow management in distributed environments spanning multiplecluster, grid and cloud systems. Recent developments in cloud computing infrastructures are presented and are referring howclouds can be incorporated into distributed workflow management, aside from local and grid systems considered so far. Severalchallenges concerning workflow definition, optimisation and execution are...

  • Applications of Tensor Analysis in Continuum Mechanics

    Publikacja

    - Rok 2018

    A tensor field is a tensor-valued function of position in space. The use of tensor fields allows us to present physical laws in a clear, compact form. A byproduct is a set of simple and clear rules for the representation of vector differential operators such as gradient, divergence, and Laplacian in curvilinear coordinate systems. The tensorial nature of a quantity permits us to formulate transformation rules for its components...

  • On weak solutions of boundary value problems within the surface elasticity of Nth order

    Publikacja

    A study of existence and uniqueness of weak solutions to boundary value problems describing an elastic body with weakly nonlocal surface elasticity is presented. The chosen model incorporates the surface strain energy as a quadratic function of the surface strain tensor and the surface deformation gradients up to Nth order. The virtual work principle, extended for higher‐order strain gradient media, serves as a basis for defining...

  • On-line ranking of split graphs

    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...

  • Integracja usług sieciowych z uwzględnieniem poziomu wiarygodności ich dostawców

    Artykuł porusza temat wiarygodności danych pobieranych z usług sieciowych. Przedstawiona została metoda oceny wiarygodności takich danych opierająca się na czterech metrykach: powszechności informacji, niezależności źródła informacji, prestiżu źródła oraz doświadczenia ze współpracy ze źródłem. Metoda ta ma zastosowanie przy integracji usług sieciowych pochodzących od wielu różnych dostawców. Metoda pozwala na automatyczną ocenę...

  • Ranking of Generation Source Locations by a Hybrid Multi-Criteria Method

    The paper presents a ranking of the locations of eight renewable energy sources (RES) made using a hybrid multi-criteria analysis method. The method is a combination of the analytical hierarchical process (AHP) method and numerical taxonomy. The considered generating sources, i.e. solar plants, biogas plants, and wind farms are sources that will significantly contribute to implementing the provisions of the energy and climate package...
