    Variations on the Author

    No full text
    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Damping of unisothermal axisymmetric bending vibrations of viscoelastic plates

    No full text
    A problem on the forced monoharmonic axisymmetric bending vibrations and dissipative heating of circular viscoelastic plate with the piezoelectric sensors and actuators is considered. Viscoelastic behavior of passive (without piezoeffect) and piezoactive materials is described using the concept of complex moduli which depend on temperature.The nonlinear coupled problem of electrothermoviscoelasticity is solved by numerical methods. The influence of the boundary conditions and temperature of disspative heating on active damping of harmonic vibrations of thin viscoelastic plates with the simultaneous use of sensors and actuators is investigated. For modeling viscoelastic properties of passive and piezoelectric materials, linear models of integral type viscoelasticity are used, which are most effective for simulating the dissipative properties of materials in the linear region. If the material characteristics depend on temperature, investigation of the influence of temperature of dissipative heating is reduced to solution of complicated nonlinear systems of differential equations.Key words: active damping, sensors, actuators.

    Numerical-analytic solution of the problem about the damping isothermal vibrations of viscoelastic rectangular plates

    No full text
    The damping of vibrations of rectangular plates by means of both viscoelastic layers and using piezoelectric inclusions is considered. For modeling viscoelastic properties of passive and piezoelectric materials, linear models of integral type viscoelasticity are used, which are most effective for simulating the dissipative properties of materials in the linear region. In the case of taking into account the influence of the piezoelectric inclusions on the rigid characteristics of the passive plate and in other types of boundary conditions (for example, with rigid fixing of the ends), the finite element method was used to solve the problem of damping. The solutions of concrete problems of damping of stationary and non-stationary vibrations of plates using analytical and finite element methods are given. On the basis of the aforementioned approach, algorithms for solving dynamical problems with both fully and partially electrodes are implemented.Key words: active damping, actuators.Pages of the article in the issue: 77 - 80Language of the article: Ukrainia

    Bending vibrations of viscoelastic plates within the Kirchhoff-Love model

    No full text
    Within the framework of the hypotheses of the classical Kirchhoff-Love theory, complete systems of resolving equations are constructed to determine the stress-strain state and the temperature of dissipative heating under steady transverse vibrations of plates made of a linear viscoelastic material, the properties of which depend on the frequency of external excitation and temperature. The equations were obtained without any preliminary suggestions about the law of temperature variation over the plate thickness. This law is determined in the process of solving the problem. The unrelated problem of vibrational bending of viscoelastic plates for complicated way of fixing a contour and different types of thermal boundary conditions is considered. Mathematical models of problems on the steady-state transverse vibrations of plates made of a linear viscoelastic material, the properties of which depend on temperature for an arbitrary law of its change over the thickness of the object. If the material characteristics depend on temperature, investigation of the influence of temperature of dissipative heating is reduced to solution of complicated non-linear systems of differential equations.Key words: viscoelastic plates, dissipative heating, Kirchhoff-Love theory.Pages of the article in the issue: 64 - 67Language of the article: Ukrainia

    Tato diplomová práce se zabývá tím, jak mohou B2B obchodníci využívat sociální média v prodeji. Na základě systematické rešerše literatury, autor zjistil, že akademici, zkoumající danou problematiku, navrhují další výzkum, a to: v kterých konkrétních krocích se dají využít sociální média v prodeji (Salo, 2017). Autor se na základě toho rozhodl zjistit, jaké sociální sítě, různé technologie a pluginy se dají využít v B2B prodeji - tzv. social sellingu. Social selling se v této práci týká primárně procesu akvizice a okrajově péčí o stávající zákazníky. Autor si vybral kvalitativní průzkum pomocí 10 hloubkových polo-strukturovaných rozhovorů, aby odhalil jak, která sociální média to jsou, tak i motivaci prodejců, proč tato média používat/nepoužívat. Aby autor dodržel správnost vyhodnocení výsledků, data byla analyzována pomocí Tématické analýzy, která v této studii vykrystalizovala 2 hlavní strategické přístupy v social sellingu. Tyto přístupy (tzv. Push a Pull strategie) obsahují praktické příklady a konkrétní aktivity, které mohou prodejci využívat v každodenní praxi. Tyto výsledky jsou prezentovány s důrazem na praktičnost a jednoduchost implementace. Tvoří proto hlavní přínos autorovo výzkumu. V poslední části autor zmiňuje výzvy a manažerská doporučení, které mohou obchodníci využít v každodenním pracovním životě.This diploma thesis focuses on social media usage in B2B sales. Based on the systematic literature review conducted by the author, he has found out that recent researchers (Salo, 2017) suggest further research in the area of how and in which sales phase should various social networking sites, technologies and plugins used. To further fill this research gap, author decided to identify these social media and their usage among B2B salespeople in the so-called social selling process. The social selling process in this thesis applies mainly to acquiring new prospects and tangentially to taking care of existing clients (follow-up step). Author has chosen a qualitative research method via conducting 10 in-depth semi-structured interviews to reveal these instruments as well as motivation of a sales person on why to use social media in the selling process. The collected data was analyzed using Thematic analysis to ensure the right procedure and to identify main themes which crystalized into 2 main strategic approaches in social selling. These approaches (Push and Pull) include practical examples of concrete activities which sales people can use in their daily jobs and are presented with focus on practicality and ease of implementation. These also form the main contribution of author`s research. In the last part, author mentions challenges in social selling and recommended managerial implications for salesforce

    Kanji-Sudokus: Integrating Chinese and Graphics

    No full text
    summary:Článek představuje metodu, jak lze technicky za pomoci METAPOSTu vykreslit sudoku s čínskými glyfy (kandži). Makra nejsou rozsáhlá a jsou v úplné podobě součástí tohoto článku. Na vykreslení sudoku jen s arabskými číslicemi můžete použít balíček sudoku; na generování, vykreslení a řešení sudoku nahlédněte, prosím, na balíček sudokubundle. Oba balíčky jsou dostupné z ctan.org. Sudoku, česky též magický čtverec, je logická hra, kterou vymyslel Howard Garns v roce 1979. Své obliby se dočkala především v Japonsku, ale prakticky se hraje po celém světě. Cílem hry je doplnit chybějící čísla 1 až 9 v předem dané předvyplněné tabulce. K dříve vyplněným číslům je potřeba dopsat další čísla tak, aby platilo, že v každé řadě, v každém sloupci a v každém z devíti čtverců byla použita vždy všechna čísla jedna až devět. Pořadí čísel není důležité. Čísla se nesmí opakovat v žádném sloupci, řádku nebo ve vnitřních malých čtvercích o devíti polích. Kdo by si to rád zkusil, nechť navštíví např. http://profuvsvet.ic.cz/data/sudoku.html nebo http://sudokuonline.cz/. Přehledně o typech sudoku, jejich algoritmech a matematickém pozadí, viz např. Wikipedie [1]. Za zajímavost stojí, že první mistrovství světa v sudoku v roce 2006 vyhrála Češka Jana Tylová z Ústí nad Labem. Turnaj v sudoku můžete absolvovat např. na mezinárodním festivalu Czech Open. Ustavující Guinnessův rekord drží z 23. února 2008 Pavel Jaselský z Vojtovce na Slovensku.summary:The article illustrates the integration of Chinese and METAPOST on a small example. The author draws a Sudoku grid, not with Hindu-Arabic numerals, but with Chinese numerals. This article demonstrates how straightforward the integration of Chinese and METAPOST has become. The source codes are included as small parts in the article commented in detail.
