Importance of tree hollows for biodiversity of mites (Acari) in the forest reserve „Śrubita” (Carpathian Mountains, south Poland)

Tree hollows harbour a specialized fauna, and mites usually are the most numerous arthropods in this microhabitat. Mite fauna in 3 types of tree hollows was studied in the forest reserve “Śrubita” near Żywiec, at an altitude of about 850 m. In total, 2037 individuals of Acari and 1414 of Oribatida, representing 72 species, were collected. Over 1200 individuals per 100 g dry weight of wood dust were collected from tree hollows. The total number of oribatid species in tree hollows was higher than in the forest floor. Most species (also dominants) were obligate members of communities of a certain type of tree hollows

New Mobile Marketing Capabilities of the Android Platform

Rapid development of the intelligent mobile devices such as smartphones and tablets created numerous opportunities for new forms of both mobile marketing and marketing in general. The emergence of smartphones complies with the drive for new ways of targeted and measur- able marketing as proposed by integrated marketing communication paradigm. New technical features such as barcode scanners, QuickResponse codes, AGPS or Near Field Communication (NFC) enable high level of personalization and engagement. The Android platform additionally increases the potential of smartphone marketing. The aim of this paper is to explore new technical features available in Android 4.0 Ice Cream Sandwich and investigate their potential use in mobile marketing. The emphasize is put on the special role that NFC may play in the marketing of the future. Besides, the significant part of the paper is committed to existing ways of marketing using smartphone and indicating the superiority of Android over other platforms in terms of results

Hypergrammar-based parallel multi-frontal solver for grids with point singularities

This paper describes the application of hypergraph grammars to drive linear computationalcost solver for grids with point singularities. Such graph grammar productions are the rstmathematical formalism used to describe solver algorithm and each of them indicates thesmallest atomic task that can be executed in parallel, which is very useful in case of parallelexecution. In particular the partial order of execution of graph grammar productions can befound, and the sets of independent graph grammar productions can be localized. They canbe scheduled set by set into shared memory parallel machine. The graph grammar basedsolver has been implemented with NIVIDIA CUDA for GPU. Graph grammar productionsare accompanied by numerical results for 2D case. We show that our graph grammar basedsolver with GPU accelerator is order of magnitude faster than state of the art MUMPSsolver

Applications of a hyper-graph grammar system in adaptive finite-element computations

This paper describes application of a hyper-graph grammar system for modeling a three-dimensional adaptive finite element method. The hyper-graph grammar approach allows obtaining a linear computational cost of adaptive mesh transformations and computations performed over refined meshes. The computations are done by a hyper-graph grammar driven algorithm applicable to three-dimensional problems. For the case of typical refinements performed towards a point or an edge, the algorithm yields linear computational cost with respect to the mesh nodes for its sequential execution and logarithmic cost for its parallel execution. Such hyper-graph grammar productions are the mathematical formalism used to describe the computational algorithm implementing the finite element method. Each production indicates the smallest atomic task that can be executed concurrently. The mesh transformations and computations by using the hyper-graph grammar-based approach have been tested in the GALOIS environment. We conclude the paper with some numerical results performed on a shared-memory Linux cluster node, for the case of three-dimensional computational meshes refined towards a point, an edge and a face

Testing for the economic and environmental impacts of EU Emissions Trading System: A panel GMM approach

The COVID‑19 pandemic has had a great impact on the economies of the EU, also with regard to the future of EU climate policy. The plan to rebuild and support the EU economy seems to place less emphasis on environmental issues as the main focus has been shifted to a quick economic recovery. One of the issues discussed in this context is the continued operation of the EU ETS. From this perspective, empirical research devoted to a thorough analysis of the impact of the EU ETS is of particular importance. At the same time, the current economic literature lacks any econometric analyzes devoted to the issues in question that would use detailed and reliable databases on EU ETS like the one provided by the Wegener Center for Climate and Global Change. The aim of this paper is to make a preliminary assessment of the effectiveness of the EU ETS in terms of reducing the actual emissions while preserving the economic growth of EU member states. The extensive empirical analysis is focused on examining the issues in question for different phases of the EU ETS and various groups of EU economies that vary in terms of economic development and the overall air pollutant emission

Testing for economic and environmental impacts of EU Emissions Trading System: A panel GMM approach

The COVID 19 pandemic has had a great impact on the European Union economies in many aspects, also with regard to the discussion on the future of EU climate policy. The plan to rebuild and support the European Union's economy, which is currently under discussion at European governments summits, seems to place less emphasis on environmental issues as the main focus is being placed on a quick recovery of EU economy in the realms of global competition. One of the issues discussed in the EU's recovery plan following the COVID19 epidemic is the continued operation of the EU ETS. In this context, empirical research devoted to a thorough analysis of the impact of the EU emissions trading program is of particular importance. At the same time, current economic literature lacks any econometric analyzes devoted to the issues in question that would use detailed and reliable databases on EU ETS like the one provided by the Wegener Center for Climate and Global Change. The aim of this paper is to make a preliminary assessment of the effectiveness of the EU ETS in terms of reducing the actual emissions to the air while preserving economic growth of EU member states. The extensive empirical analysis is focused on examining the issues in question for different phases of the EU ETS and various groups of EU economies that vary in terms of economic development and the overall air pollutant emission

Two-dimensional HP-adaptive Algorithm for Continuous Approximations of Material Data Using Space Projection

In this paper we utilize the concept of the L2 and H1 projections used toadaptively generate a continuous approximation of an input material data inthe finite element (FE) base. This approximation, along with a correspondingFE mesh, can be used as material data for FE solvers. We begin with a brieftheoretical background, followed by description of the hp-adaptive algorithmadopted here to improve gradually quality of the projections. We investigatealso a few distinct sample problems, apply the aforementioned algorithms andconclude with numerical results evaluation
