  • New Air-Jet Weft-Insertion System Without An Air-Guide And With Double-Holed Relay Nozzles - A Study Of Double-Holed Relay Nozzles 
    Natarajan, Vijay; Prášil, Vladimír; Egrt, F.; Hruš, M. (Textile Inst Intl Headquarters, 1993)
    In this paper, a new air-jet weft-insertion system, which does not require any air-guide, such as a confusor or profiled reed, is discussed. Characteristics of the new double-holed relay nozzles, studied by using Pitote-tube ...
  • New findings relating to stability of the OE rotor spinning process 
    Ursíny, Petr; Mägel, Matthias (1995)
    An increase in rotor open-end spinning machine capacity and measures for a higher yarn spinning limit are always measured against the machine efficiency which is significantly affected by yarn breakages and their elimination. ...
  • A note on the convexity theorem for mean values of subtemperatures 
    Brzezina, Miroslav (Suomalainen Tiedeakatemia, 1996)
    In this note we prove the finiteness of mean values of subtemperatures over level surfaces of the Green function and we give a capacitary interpretation of the corresponding ''mean value measure''.
  • On Consecutive labeling of plane graphs 
    Bača, Martin (1991)
    This paper concerns a labeling problem of the plane graphs Pmn. The present paper describes a magic vertex labeling and a consecutive labeling of type (0,1,1). These labelings combine to a consecutive labeling of type ...
  • On the sliding time in flotation 
    Nguyen, Anh Vu (1993)
    The sliding interaction between a particle and a bubble in flotation is discussed in the context of induction time, the important measure of flotation behavior, and is modeled to calculate the sliding time. This permits ...
  • PC software for crystallographic space groups and its application in symmetry analysis of domain structures 
    Davies, Brian L.; Dirl, R.; Janovec, Václav; Zikmund, Zdeněk (Taylor & Francis Ltd, 1997)
    An integrated package of programs has been developed to investigate the structures and representations of crystallographic space groups. The programs, written in PASCAL and C, are made user friendly by additional programs ...
  • Peculiar behaviour of the loom's back-rest roller 
    Nosek, Stanislav (1997)
    This paper presents an analysis of the dynamic model of the back-rest roller motion. On modern high-speed looms with growing weaving resistance, the normal beat-up pulse delivered by the conventional reed is not able to ...
  • Permanently corona charged filter materials of staple fibers 
    Kolínová, Marcela; Jirsák, Oldřich; Wadsworth, L. (1997)
    Permanent electrical charging of fibrous filter materials by corona is one of the ways to increase filtration efficiency without increase in the pressure drop. The authors present teoretical and experimental knowledge of ...
  • Phonetic alphabet for speech recognition of Czech 
    Nouza, Jan; Psutka, Josef; Uhlíř, Jan (Czech Technical University, 1997)
  • Photorefractive grating fixing in KNbO3 by ferroelectric domains 
    Cudney, Richard S.; Bernasconi, Pietro N.; Zgonik, Marko; Fousek, Jan; Günter, Peter N. (1997)
    We report observations of photorefractive grating fixing in potassium niobate at room temperature by means of ferroelectric domains. A grating is recorded while the crystal is simultaneously depoled. By repoling the crystal, ...
  • Prediction of hand from measurable characteristics 
    Militký, Jiří; Bajzík, Vladimír (1999)
    Hand represents the main organoleptic characteristics of clothes. Evaluation of this characteristic is based on the base of subjective meanings. The subjective handle is closely connected with the objective measureable ...
  • Prediction of hand from measurable characteristics 
    Militký, Jiří; Bajzík, Vladimír (1998)
    Hand represents the main organoleptic characteristics of clothes. Evaluation of this characteristic is based on the base of subjective meanings. The subjective handle is closely connected with the objective measurable ...
  • Pulse Method Used To Identify Material Properties In Linear Viscoelastic Media 
    Humen, Vladimír; Potěšil, Antonín (Pergamon-Elsevier Science Ltd, 1993)
    The experimentally observed affine similarity of the time profiles of a longitudinal deformation pulse propagating in a more or less one-dimensional linear viscoelastic body has been used by the authors to develop a pulse ...
  • Pyromagnetic domain walls connecting antiferromagnetic non-ferroelastic magnetoelectric domains 
    Přívratská, Jana; Janovec, Václav (Taylor & Francis Ltd, 1997)
    We describe a group-theoretical procedure that enables one to find necessary conditions for the appearance of spontaneous magnetization in domain walls. We illustrate the derivation of wall symmetries on example of Cr2O3 ...
  • A sample analysis of domain walls in simple cubic phase of C60 
    Saint-Grégoire, Pierre; Janovec, Václav; Kopský, Vojtěch (Taylor & Francis Ltd, 1997)
    An analysis of possible structure of a domain wall (111) in rotational twin of fullerene C 60 is performed with use of sectional layer groups. The eight possible domain states are described and it is shown that there exist ...
  • Shortness coefficients of simple 3-polytopal graphs with edges of only two types 
    Tkáč, Michal (1992)
    We consider two classes of simple 3-polytopal graphs whose edges are incident with either two 5-gons or a 5-gon and q-gon (q = 26 or 27). We show that the shortness coefficient is less than 1 for both of these classes. © 1992.
  • The sliver machine - a means for reducing the number of stages in sliver production 
    Ursíny, Petr; Mägel, Matthias (1994)
    A description is given of the machine - a carding machine with stationary flats and a very potential for levelling long-term and short-term irregularities - is discussed in relation to rotor open-end spinning. The satisfactory ...
  • Some graphical aids for univariate exploratory data analysis 
    Militký, Jiří; Meloun, Milan (Elsevier Science Bv, 1993)
    The main parts of exploratory data analysis (EDA) are discussed. For data presentation the quantile plot and quantile-box plot are proposed. Special techniques for empirical probability density construction and empirical ...
  • Some remarks on domination in cubic graphs 
    Zelinka, Bohdan (Technical university of Liberec, Czech RepublicTechnická Univerzita v Liberci, 1996)
    We study three recently introduced numerical invariants of graphs, namely, the signed domination number γs, the minus domination number γ- and the majority domination number γmaj. An upper bound for γs and lower bounds for ...
  • Spontaneous strain in ferroelastic incommensurate [N(CH3)4]2CuCl4 crystals 
    Müller, Volkmar; Fuith, Armin H.; Fousek, Jan; Warhanek, Hans; Beige, Horst (1997)
    The temperature dependence of spontaneous strain is investigated in the ferroelastic lock-in phase of [N(CHs),&CuCIi crystals by thermal mechanical analysis. The critical index of the order parameter modulus is found to ...
