Design an Improved Structure for 10-Bit Pipeline Analog to Digital Converter Based on 0.18µm CMOS Technology
Authors: Rezapour Arash , Setoudeh Farbod , Tavakoli Mohammad Bagher 
Published: December 2019

Abstract
This paper proposed a novel structure of a 10-bit, 400MS/s pipelined analog to digital convertor using 0.18 µm TSMC technology. In this paper, two stages are used to converter design and a new method is proposed to increase the speed of the pipeline analog to digital convertor. For this purpose, the amplifier is not used at the first stage and the buffer is used for data transfer to the second stage, in the second stage an amplifier circuit with accurate gain of 8 that is open loop with a new structure was used to speed up, also the design is such that the first 4 bits are extracted simultaneously with sampling. On the other hand, in this structure, since in the first stage the information is not amplified and transferred to the second stage, the accuracy of the comparator circuit should be high, therefore a new structure is proposed to design a comparator circuit that can detect unwanted offsets and eliminate them without delay, and thus can detect the smallest differences in input voltage. The proposed analog to digital convertor was designed with a resolution of 10 bits and a speed of 400MS/s, with the total power consumption 74.3mW using power supply of 1.8v.
Transport of Solid Particles with Fluid Flow in Rotating Pipes

Published: December 2019

Abstract
The article addresses the recent problem of borehole lifting of oil containing sand solids. The presence of sand in oil produced results in a reduced operating life of downhole equipment. The problem of preventing sanding up and sand formation in pumping equipment may be solved and stable sand production may be ensured by producing oil using borehole screw pumps with a surface-type drive, in which the screw is rotated by rotating hollow rods. Rotating hollow rods improve carry-over of sand particles to the surface with rotational oil flow by imparting additional momentum to these particles. Rotational variables of the pipe (cylinder) that enables transport of solids are set only for the air flow moving in a horizontal pipe (cylinder). The purpose of the study is to establish pipe rotational variables in directional wells that enable stable sand transport with fluid flow. Work results have been obtained from numerical studies using the differential equation system and rules of theoretical solid movement, computer simulation and experimental results processing at a laboratory facility. Theoretical study results have been acknowledged by experimental studies. The work establishes the criteria that allow defining the speed range of directional hollow rods that enables carry-over of solids to the surface with fluid flow. Study results may be used to produce oil with submersible screw pumps with a surface-type drive that use hollow sucker rods for pump down.
Best predictors in logarithmic distance between positive random variables
Authors: Gzyl H. 
Published: December 2019

Abstract
The metric properties of the set in which random variables take their values lead to relevant probabilistic concepts. For example, the mean of a random variable is a best predictor in that it minimizes the L
2 distance between a point and a random variable. Similarly, the median is the same concept but when the distance is measured by the L
1 norm.
Also, a geodesic distance can be defined on the cone of strictly positive vectors in ℝ
n
in such a way that, the minimizer of the distance between a point and a collection of points is their geometric mean.
That geodesic distance induces a distance on the class of strictly positive random variables, which in turn leads to an interesting notions of conditional expectation (or best predictors) and their estimators. It also leads to different versions of the Law of Large Numbers and the Central Limit Theorem. For example, the lognormal variables appear as the analogue of the Gaussian variables for version of the Central Limit Theorem in the logarithmic distance.
Fractional calculus pertaining to multivariable I-function defined by Prathima
Authors: Kumar D. , Ayant F. Y. 
Published: December 2019

Abstract
In this paper, we study a pair of unified and extended fractional integral operator involving the multivariable I-functions and general class of multivariable polynomials. Here, we use Mellin transforms to obtain our main results. Certain properties of these operators concerning to their Mellin-transforms have been investigated. On account of the general nature of the functions involved herein, a large number of known (may be new also) fractional integral operators involved simpler functions can be obtained. We will also quote the particular case of the multivariable H-function.
Temporal ‘Since’ in Slovak: Conjunction(s) and Aspect Choice – A Corpus Study
Authors: Kyselica Paula , Genis René M. 
Published: December 2019

Abstract
It has recently been shown by especially [1] through [4] and [12] for Russian and by [8] and [9] for Polish that conjunctions corresponding to Dutch sinds (cf. also [1], [2], [3]) and English since (cf. also [7], [10]) have temporal functions, which are subject to restrictions on the choice of tense and aspect. Ultimately these restrictions can be related to the semantic input of tense and aspect into complex sentences with these connective items. For Polish extensive data provided by corpus research enabled us to shed light on the usage and restrictions in this area and also to establish which constellations with particular conjunctions are more or less likely or not possible (cf. [8], [9]). In the present contribution we present freshly sourced quantitative Slovak SNK-corpus data. We consider the sixteen logically possible tense-aspect constellations, and the Slovak connective items: odkedy; odvtedy, čo / ako; od chvíle, keď / čo / ako; od tých čias, čo / ako; od tej doby, čo / ako. This quantitative data study is intended to pinpoint the areas of future research; for this purpose at certain instances comparisons are made with Polish, the only other language we have such data for to date.
Corpus-Supported Semantic Studies: Part/Whole Expressions in Russian
Authors: Boguslavsky Igor , Iomdin Leonid 
Published: December 2019

Abstract
We investigate valency properties of partials – words and constructions that express the Part/Whole relation, primarily in Russian, offering new observations largely based on the Russian National Corpus. Special attention is given to such lexical units as bol’šinstvo ‘majority’, men’šinstvo ‘minority’, čast’ ‘part’, protsent ‘percentages’, v bol’šinstve svoem ‘in its <their, etc.>majority’, ‘po bol’šej časti ‘for the most part’, etc.
Kinship Terminology in Western Slavic Languages Based on Corpora Analysis
Authors: Kobzová Jana 
Published: December 2019

Abstract
This paper is discussing kinship arrangements and more generally families of Western Slavs based on linguistic and corpora data. It is argued here that we can find correlation between lexicon and society, and that studying of lexicon can provide supportive data for society examination. In this paper we used corpora data that provides us with reliable information about lexicon that is truly used by speakers of Western Slavic languages and provided possible explanations for changes occurring in this part of vocabulary. Paper is divided into three main parts, one discussing relations between social reality and kinship terminology, while the second is discussing data from corpora. Third part is devoted to drawing conclusions.
The Dialekt Corpus and Its Possibilities
Authors: Goláňová Hana , Waclawičová Martina 
Published: December 2019

Abstract
DIALEKT, a corpus of Czech dialects, has been continuously curated and expanded by the Spoken Corpora section of the Institute of the Czech National Corpus. The following paper aims first to give a concise characteristic of the corpus, addressing its sociolinguistic parameters and possible subcorpora derivable thereof, its two-layer approach to the transcription of dialect recordings, and lemmatization & morphological tagging of the corpus. Subsequently, we move on to examples of how linguists can use the corpus and discuss two related projects which expand upon currently available possibilities: an archive of dialect-specific differential phones of the Czech language (completed) and an interactive web environment for spatial map-based visualization of data from all kinds of spoken corpora (in preparation). Thanks in part also to these additional tools, the DIALEKT corpus should serve both experts in the field as well as the general public.
Parts of Speech in NovaMorf, A New Morphological Annotation of Czech
Authors: Petkevič Vladimír , Hlaváčová Jaroslava , Osolsobě Klára , Svášek Martin , Šimandl Josef 
Published: December 2019

Abstract
A detailed morphological description of word forms in any language is a necessary condition for a successful automatic processing of linguistic data. The paper focuses on a new description of morphological categories, mainly on the subcategorization of parts of speech in Czech within the NovaMorf project. NovaMorf focuses on the description of morphological properties of Czech word forms in a more compact and consistent way and with a higher explicative power than approaches used so far. It also aims at the unification of diverse approaches to morphological annotation of Czech. NovaMorf approach will be reflected in a new morphological dictionary to be exploited for a new automatic morphological analysis (and disambiguation) of corpora of contemporary Czech.
Improving Nominalized Adjectives Tagging
Authors: Osolsobě Klára , Žižková Hana 
Published: December 2019

Abstract
Part of speech transitions represent an interesting issue in terms of Automatic Morphological Analysis (AMA). In these cases, two parts of speech have to be considered: initial and final. However, their automatic recognition is complicated by the same form. This article presents the results of a corpus study aimed at mapping nominalized adjectives tagging with a focus on detecting candidates for nominalization among frequent adjectives. Analysis of the data obtained from the ČNK SYN v5 corpus shows different reasons for incorrect tagging. Taking into account these reasons, we propose three solutions for the improvement nominalized adjectives tagging.
Non-Systemic Valency Behavior of Czech Deverbal Nouns Based on the NomVallex Lexicon
Authors: Kolářová Veronika , Vernerová Anna , Verner Jonathan 
Published: December 2019

Abstract
In order to describe non-systemic valency behavior of Czech deverbal nouns, we present results of an automatic comparison of valency frames of interlinked noun and verbal lexical units included in valency lexicons NomVallex and VALLEX. We show that the non-systemic valency behavior of the nouns is mostly manifested by non-systemic forms of their actants, while changes in the number or type of adnominal actants are negligible as for their frequency. Non-systemic forms considerably contribute to a general increase in the number of forms in valency frames of nouns compared to the number of forms in valency frames of their base verbs. The non-systemic forms are more frequent in valency frames of non-productively derived nouns than in valency frames of productively derived ones.
Towards Reciprocal Deverbal Nouns in Czech: From Reciprocal Verbs to Reciprocal Nouns
Authors: Kettnerová Václava , Lopatková Markéta 
Published: December 2019

Abstract
Reciprocal verbs are widely debated in the current linguistics. However, other parts of speech can be characterized by reciprocity as well – in contrast to verbs, their analysis is underdeveloped so far. In this paper, we make an attempt to fill this gap, applying results of the description of Czech reciprocal verbs to nouns derived from these verbs. We show that many aspects characteristic of reciprocal verbs hold for reciprocal nouns as well.

Published: December 2019

Abstract
Biodegradable metallic implants are materials that serve as a temporary implants and scaffolds. They degrade directly in vivo and therefore eliminate need for secondary surgical intervention. They are often made of metals such as magnesium, iron, zinc and can be modified by coating with the inorganic or polymeric layer. In this work iron-based biomaterial was prepared and modified with polymeric (polyethyleneimine, PEI) layer. Its degradation behavior was studied under conditions of simulated body fluids at 37 ± 0.2 °C in the form of static immersion tests. It has been shown that the surface modification caused an acceleration of degradation of the material and also had an influence on the corrosion mechanism.
Multidisciplinary Project of Historical Aircraft Virtual Reconstructions as a Way of Popularizing Science
Authors: Szafran Krzysztof , Kramarski Ireneusz 
Published: December 2019

Summary
Research and development institutions have a wide range of competences in their fields of scientific and technical activity. They also often have some unique capabilities to do research and development (R&D). However, these possibilities are often known only to a small group of industry specialists and few parliamentary representatives. There is also a lack of information about research capabilities of R&D institutes in industry, especially among small and medium enterprises.
The aim of the article is to present the concept of a multidisciplinary research project aimed at testing by a scientific research institution the possibility of using social media and modern techniques of visualization and computer simulation in aircraft reconstruction engineering. The authors propose to try the approach of marketing campaign capabilities of research and development institutions in a way similar to the action of raising funds for some purpose, but unlike this type of action, the campaign should be aimed at increasing technical awareness of the society. As part of the pilot program, the authors propose a virtual reconstruction of the construction of the Polish PZL P-50 Jastrząb fighter plane whose two prototypes were created before the outbreak of World War II. On the basis of analyses, calculations and computer simulations, in the second phase it is proposed to make a preliminary design of the aircraft with performance similar to the PZL P-50 on the basis of modern knowledge and the latest technologies available in aviation technology. One of the ways to encourage people to undertake creative work, including the restoration of historical objects, will allow them to gain valuable employment possibilities in R&D institute [19].
The combination of marketing techniques, using the power of social media, with the strictly engineering challenges of recreating a historic aircraft and designing its modern equivalent, gives the possibility to confirm the technical and organizational capabilities of the research and development institutions. On the basis of the above activities, a database of people interested in research and development activities of scientific institutions and their contribution to the reconstruction of historically important products of Polish technical thought will be built.
The halo effect of foreign brands on the misclassification of local brands
Authors: Sulhaini Sulhaini , Rinuastuti Baiq Handayani , Sakti Dwi Putra Buana 
Published: December 2019

Abstract
Consumers generally lack the ability to identify brands’ true origins, with their attribution of the wrong origins to well-known brands showing their underlying attitudes. This study suggests that the misclassification of local brands in Indonesia is driven by the halo effect of foreign brands (i.e., brands from Japan, South Korea and China) and the inferior image of locally made products. These constructs, however, differently affect Indonesian consumers’ attitudes towards local brands. This study strongly suggests that, when consumers misperceive local brands as being from more developed countries, they tend to show negative attitudes towards local brands. This study provides useful recommendations for both local and foreign brand owners seeking strategies to enhance competitiveness in the Indonesian market.
The Impact of Dynamic Capabilities on Organizational Effectiveness
Authors: Kareem Mohanad Ali , Alameer Alaa Abdulameer Ahmed 
Published: December 2019

Abstract
This paper aims to investigate the impact of dynamic capabilities constructs i.e. sensing capability, learning capability, and reconfiguration capability on organizational effectiveness in the selected Iraqi public universities context. This study adopted the survey method to collect primary data. An online questionnaire was distributed to around 342 employees, out of which 215 completed questionnaires were obtained. The data were collected during the period from 02-08-2018 to 03-10-2018. The reliability and validity of the dimensions are assessed through confirmatory factor analysis (CFA) and the hypotheses are tested by using structural equation modeling SEM. The analytical results indicate that sensing capability does not have a positive impact on organizational effectiveness while learning capability and reconfiguration capability have a positive impact on organizational effectiveness. Thus, this study provides a better understanding of the effects of dynamic capabilities. The results of this study have the potential to help the decision-makers of universities to develop learning capability and reconfiguration capability, in turn, universities will be able to achieve superior organizational effectiveness.

Published: December 2019

Abstract

Introduction.
The paper aims to identify and systematise basic psychological factors which can influence athletes’ training and competitive activity.

Material and methods.
In order to achieve the aim of the study, we carried out an expert survey and analysed its results statistically. The survey, whose concordance coefficient was 0.78, was completed by 12 experts in the field (sports scientists and highly qualified athletes).

Results.
The study of the scientific and methodological literature about psychological correction taking into account the practice of athletes’ training made it possible to formulate and systematise a number of key psychological factors (volitional, strategic, perceptive-aimed, anticipatory, managerial, psychophysiological, intellectual, introspective, and motivational) that affect the mental state and training process of athletes. The content and forms of the manifestation of psychological factors during competitive activity are examined, and their interrelations are studied. Integral indicators of psychological factors which influence competitive activity in Olympic sports are determined, and their priority of importance is examined.

Conclusions.
According to the experts’ opinions, among the integral indicators of the psychological factors influencing athletes’ activity, the leading ones are motivational, volitional, and psychophysiological factors. The results of the expert survey concerning the psychological factors influencing Olympic sports (game, cyclic, and complex coordination sports as well as martial arts) are analysed.

The Oral History Interview – A Relationship and Space of Trust
Authors: Vrzgulová Monika 
Published: December 2019

Abstract
The oral history interview is a “multi-layered communicative event”. It is a unique, active event, reflective of a specific culture and of a particular time and space. Interviews, more precisely biographical interviews, are the tool I have been using for decades. The relationship between the interviewer and interviewee is, therefore, an essential question for me. I interview people to find out what happened to them, how they felt about it, how they recall it and what wider public memory they draw upon. Focused on the biographical narratives, as well as in-depth and repeated interviews, I have constantly faced ethical and moral questions in accordance with my role as a listener, and as a partner in the interview, but also as a scholar with the goal of using the interview in my scientific work. In my text, I would like to develop Hourig Attarian’s inspiring ideas on self-reflexivity, which brings to light the grey zones that we encounter in our work. This is often a difficult and fragile process. It is central to the connections that I create with the interviewees in my projects. These people always affect the course of my work, but also me personally. This balancing act is an exercise. I try to understand my own limits, I try to push my own boundaries, and assess how each of these circumstances impacts my research.
