Generalized efficient solutions to one class of vector optimization problems in Banach spaces
No full textIn this paper, we study vector optimization problems in Banach spaces for essentially
nonlinear operator equations with additional control and state constraints. We assume that
an objective mapping possesses a weakened property of lower semicontinuity and make no assumptions
on the interior of the ordering cone. Using the penalization approach we derive both
sufficient and necessary conditions for the existence of efficient solutions of the above problems.
We also prove the existence of the so-called generalized efficient solutions via the scalarization
of some penalized vector optimization problems
Topological Aspects of Scalarization in Vector Optimization Problems
No full textIn this paper, we study vector optimization problems in partially ordered Banach
spaces. We suppose that the objective mapping possesses a weakened property of lower semicontinuity
and make no assumptions on the interior of the ordering cone. We derive sufficient
conditions for existence of efficient solutions of the above problems and discuss the role of topological
properties of the objective space. We discuss the scalarization of vector optimization
problems when the objective functions are vector-valued mappings with a weakened property of
lower semicontinuity. We also prove the existence of the so-called generalized efficient solutions
via the scalarization process. All principal notions and assertions are illustrated by numerous examples
On existence of efficient solutions to vector optimization problems in Banach spaces
Get PDFIn this paper, we present a new characterization of lower semicontinuity of vectorvalued mappings and apply it to the solvability of vector optimization problems in Banach spaces. With this aim we introduce a class of vector-valued mappings that is more wider than the class of vector-valued mappings with the "typical" properties of lower semi-continuity including quasi and order lower semi-continuity. We show that in this case the corresponding vector optimization problems have non-empty sets of efficient solutions
S. I. Gessen in Memoirs and Assessments of V. V. Zenkovsky: Page from Intellectual History of Russian Emigration
Get PDFThe relationship between S. I. Gessen and V. V. Zenkovsky, representatives of Russian philosophical, psychological, pedagogical and social thought, is considered as an episode of the intellectual history of the Russian diaspora. It is argued that the image of S. I. Gessen, formed in the scientific works and memoirs of a famous teacher, complements the idea of his personality, of the position S. I. Gessen held in the scientific, pedagogical and social life of the emigration. An analysis of the relationship between two thinkers over a quarter of a century is presented. The conclusion is drawn about the “internal dialogue” between them, which developed on the pages of emigre periodicals, was recorded in correspondence with like-minded people and became the subject of reflection and self-reflection in scientific works. The author pays special attention to assessments of the theoretical contribution of S. I. Gessen to Russian and European philosophical and pedagogical thought, which are given in reviews and surveys, the essay “Russian Pedagogy in the XX century” and “History of Russian Philosophy”. It is shown that in this context, the responses to the death of S. I. Gessen and memories of him, which make it possible to determine the attitude of V. V. Zenkovsky not only to S. I. Gessen the thinker, but also to man, acquire great importance
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
TeX v jednoduchém unixovém prostředí
Get PDFsummary:Při ladění TeXového dokumentu potřebujeme mnohokrát opakovaně pouštět TeX, podívat se, jak dopadl výsledek v prohlížeči DVI nebo PDF souboru, mrknout na výpis TeXu na terminálu, podívat se případně do logu a celou činnost opakovat. V tomto článku je ukázáno, jak tuto práci dělá autor článku. Proces "editor-TeX-kuk" je zde podporován jednoduchými unixovými nástroji: bashovým skriptem texloop, který si autor pro tyto účely vytvořil, dále terminálem Xterm a jednoduchým editorem, který umí navázat na klávesovou zkratku spuštění příkazu v systému. Čtenář se zde může inspirovat a přizpůsobit tyto nástroje svým vlastním potřebám. V článku je popsána funkce skriptu texloop, dále je neformálně rozveden dlouholetý vývoj autorova vztahu k textovým editorům a konečně je zde uvedena konfigurace terminálu Xterm, aby vyhovoval českému prostředí jak v kódování ISO-8859-2, tak v kódování UTF-8. Pro kódování UTF-8 si v závěru článku vygenerujeme TeXový formát csplain.summary:By debugging a TeX document it is necessary many times repeatedly to run TeX, to look for the result in DVI or PDF file, to gander the TeX output on the terminal, or eventually to have a look in the log-file, and all that action to repeat. In the paper it is show, how this work is made by author. The process '‘'editor-TeX-look' is supported by simple Unix tools: bash script texloop, created by author for these purposes, Xterm terminal and a simple editor, which is able to link to the shortcut key the activation of a system command. The reader could be inspired with the solution and to adapt these tools to his/her own needs. In the paper the function of the texloop script is described, and further the longstanding evolution of the author's relation to text editors is informal elaborated and finally a configuration of Xterm terminal, suitable for the czech environment with both ISO-8859-2 and UTF-8 encoding is introduced. For UTF-8 encoding the TeX format csplain is generated at the end of the paper

AUTHOR BOOK
No full textVytvořil jsem autorskou knihu o čtyřiceti stránkách s ilustracemi a minimem textu. Kniha je černobílá, dominuje v ní tušová kresba štětcem a perem. Kromě té je v knize ale i text, který slouží jako poetické doplnění ilustrací.
Obsah knihy se zaměřuje na úzký kruh přátel a zároveň vypovídá o autorovi jak vybranými motivy, situacemi tak linkou.
Vyznění knihy je spíše pocitové, má zanechat dojem, ne popisně vysvětlovat.ObhájenoI have created author book that has 40 pages with ilustrations and minimum of text. The book is black and white and contains ink drawings. There is also text poetically coresponding with pictures
