Opis:
In this article, I will discuss the position of King, Keohane and Verba. Referring directly to the issues of sociology and political science, these authors set the main goal of their considerations to show how to design a research that brings accurate conclusions about social and political life. Many of their comments are applicable to research in other fields of science, including in psychology. Qualitative, and not only quantitative, methods can be very useful in researching the IT environment. Educational organizations can apply the conclusions from studies which connect the qualitative and quantitative methods to assist in the staff development to achieve organizational goals. Also -in process of proper recruitment of leaders in business management or to assist the stuff to raise the performing of professional tasks, even self-development of stuff members should also use the scientific research findings. Hence I consider both – quantitative but also qualitative methods – worth quoting and analyzing.

Opis:
.
This paper is concerned with a numerical method for solving the problem Δu=f in Ωc (=intR2\Ω), (du/dn)|Γ=g, where ΩR2 is a polygon and Γ is the boundary of Ω. The method is based on coupling finite and boundary element techniques. To compensate for the loss of smoothness of the solution u near the corners of the polygon Ω we refine the triangulation without changing the number of triangles. We apply the affine triangular Lagrangean element of degree kN and the Lagrangean boundary element of degree k−1 to obtain the optimal order of convergence via the Galerkin projection.

Opis:
The suspension is the component decisive about safety of drive of cars, in which dumping elements have essential meaning, which the most often are telescopic hydraulic shock-absorbers. Therefore, in exploitation process so important investigations of their technical condition are in track which opinion of their usefulness should be made not only to more far exploitation, but also the identification of typical damages. The common used method in practical ways of diagnosing of shock-absorber in article was introduced. There are two methods of investigations: built from and shock-absorber built-in in vehicle suspension. In first method - in support about indicatory graph, the characteristic of suppression be appointive. They are the basis to diagnostic opinion of technical condition of studied damper. In second method the results of investigations have approximate character. From those methods the most often used station control of vehicles in Poland - method post EUSAMA and BOGE in article were described, which used in investigations the harmonic excitatory of vibrations stimulant to vibrations unsprung and sprung masses of vehicle. The car is so folded, vibrate mechanical stimulated by excitator to vibrations arrangement. The vibro-acoustic methods of analyses' of signals in article were introduced, which can be practical in investigations of diagnostic shock-absorber. They are then the method of multidimensional analysis of signal - the Short-Time Fourier Transforms (the STFT), Wigner - Ville'a and Wavelet.

Opis:
The article presents in a review way the most important numerical methods used in modern fluid mechanics. The individual chapters discuss Finite Difference Method, Finite Volume Method, Lattice Boltzmann Method, Discrete Element Method and Smoothed Particle Hydrodynamics. The aim of the article is to familiarize the reader with the most important concepts, features and mathematical equations used in particular methods. The article is intended mainly for people who want to get acquainted with the current possibilities of numerical modelling in the field of broadly understood fluid mechanics. The material is intended to facilitate the decision on how to implement the planned play research.

Tools for estimating fake/non-prompt lepton backgrounds with the ATLAS detector at the LHC

Opis:
Measurements and searches performed with the ATLAS detector at the CERN LHC often involve signatures with one or more prompt leptons. Such analyses are subject to `fake/non-prompt' lepton backgrounds, where either a hadron or a lepton from a hadron decay or an electron from a photon conversion satisfies the prompt-lepton selection criteria. These backgrounds often arise within a hadronic jet because of particle decays in the showering process, particle misidentification or particle interactions with the detector material. As it is challenging to model these processes with high accuracy in simulation, their estimation typically uses data-driven methods. Three methods for carrying out this estimation are described, along with their implementation in ATLAS and their performance.

Opis:
In this paper a comparison of different types of maximum power point search methods for the photovoltaic panels is presented. The methods that represent each group of maximum power point techniques will be implemented in the software that allows to test the behaviour of photovoltaic panels in different environment conditions including partial shading. In this paper each implemented method was compared including time of convergence with the maximum power point, tracking error and differences in the energy obtained from photovoltaics during the simulation time. The algorithms were compared under both uniform lighting and partial shade conditions.

Opis:
In this paper we present implementation of the MUSCL-Hancock method for numerical solutions of the Euler equations. As a result of the internal complexity of these equations solving them numerically is a formidable task. With the use of the original C++ code, we developed and presented results of a numerical test that was performed. This test shows that our code copes very well with this task.

Opis:
This study presents detailed systematics of quality assessment methods for marketing organizations diving it into three groups: qualitative, quantitative and qualitative-quantitative (mixed) methods. The first group includes methods such as: marketing audit, marketing excellence evaluation and review oftheethical and social responsibility of the organization. The second group is: sales analysis, market share analysis, impact analysis with marketing expenditures on sales area, financial analysis, profitability and efficiency control, marketing effectiveness ranking and observation on customer satisfaction. The last group includes methods: balanced scorecard and marketing benchmark. Approach towards assessing the quality of organization's marketing activities requires using one particular method. Due to big number of existing methods for assessing the quality of marketing activities, a question arises: which one will allow us fully assess the activity.

Opis:
The large effluxes generated by high-tech plasmas force plasmas to non-equilibrium conditions. This implies that plasma features are decoupled from each other and that therefore different methods have to be used quasi-simultaneously to characterize the plasma. Even more insight in plasmas and methods is obtained if polydiagnostics is applied to a series of plasma conditions that gradually differ in equilibrium departure. After discussing methods of passive and active spectroscopy, we apply polydiagnostics on an argon plasma operated in open air. By introducing H2 and reducing the power we approach conditions of cool atmospheric plasmas (CAPs). It is seen that especially the passive methods for the electron temperature determination are very sensitive to the degree of equilibrium departure suggesting that active spectroscopy is preferable. However, one should realize that lasers can easily heat cool plasmas. This is due to the fact that the ionization degree of (semi-) CAPs is small.
