    • ESTIMATION OF THE LATERAL AERODYNAMIC COEFFICIENTS FOR SKYWALKER X8 FLYING WING FROM REAL FLIGHT-TEST DATA 

      Autor: Mohammadi Farhadi , Rahman; Kortunov , Vyacheslav; Molchanov , Andrii; Solianyk , Tatiana
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      Stability and control derivatives of Skywalker X8 flying wing from flight-test data are estimated by using the combination of the output error and least square methods in the presence of the wind. Data is collected from ...

    • H2 PERMEATION BEHAVIOR OF Cr2AlC AND Ti2AlC MAX PHASE COATED ZIRCALOY-4 BY NEUTRON RADIOGRAPHY 

      Autor: Tang , Chongchong; Grosse Karl, Mirco; Trtik , Pavel; Steinbrück , Martin; Stüber , Michael; Seifert , Hans Jürgen
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      Hydrogen uptake by nuclear fuel claddings during normal operation as well as loss of coolant during design basis and severe accidents beyond design basis has a high safety relevance because hydrogen degrade the mechanical ...

    • AUTOMATIC WINDING GENERATION USING MATRIX REPRESENTATION - ANFRACTUS TOOL 1.0 

      Autor: Ouamara , Daoud; Dubas , Frédéric; Benallal , Mohamed Nadjib; Randi , Sid Ali; Espanet , Christophe
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      This paper describes an original approach dealing with AC/DC winding design in electrical machines. A research software called “ANFRACTUS Tool 1.0”, allowing automatic generation of all windings in multi-phases electrical ...

    • Editorial: FAREWELL AND WELCOME NEW EDITOR-IN-CHIEF 

      Autor: Adlerová , Iva
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      My seven years with Acta Polytechnica ended on June 30. The opportunity to lead this journal from a local list of reviewed periodicals to the prestigious databases – Web of Science, Scopus, Inspec, CAS and more – was a ...

    • QUASI-EXACTLY SOLVABLE SCHRÖDINGER EQUATIONS, SYMMETRIC POLYNOMIALS AND FUNCTIONAL BETHE ANSATZ METHOD 

      Autor: Quesne , Christiane
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      For applications to quasi-exactly solvable Schrödinger equations in quantum mechanics, we consider the general conditions that have to be satisfied by the coefficients of a second-order differential equation with at most ...

    • BATHYMETRY FROM WORLDVIEW-3 SATELLITE DATA USING RADIOMETRIC BAND RATIO 

      Autor: Parente , Claudio; Pepe , Massimiliano
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      The use of optical satellite sensors allows to obtain bathymetry data on large area ina short time and in a cheap way. In addition, in particular places where it is difficult to carry out the survey by classic methods, the ...

    • LEAD-TIME, INVENTORY, AND SAFETY STOCK CALCULATION IN JOB-SHOP MANUFACTURING 

      Autor: Sellitto Afonso, Miguel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      The purpose of this article is to present a method for calculating the lead-time, the inventory, and the safety stock or buffer in job shop manufacturing, which are essentially stochastic variables. The research method is ...

      Autor: Kravanja , Sebastjan; Sovják , Radoslav
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      A series of cratering experiments were performed where the response of the Ultra-High-Performance Fibre-Reinforced Concretes with various fibre volume fractions to the high- velocity projectile impact loading was investigated. ...

    • INTELLIGENT CONTROLLER FOR TRACKING A 14-INCH CELESTRON TELESCOPE 

      Autor: Attia A., Abdel-Fattah
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      The paper proposes a design of two fuzzy and Proportional-Integral-Derivative (PID) controllers for a position tracking of the 1400 Celestron telescope. The position responses; right ascension and declination in such a way ...

    • MINIMAL NON-INTEGER ALPHABETS ALLOWING PARALLEL ADDITION 

      Autor: Legerský , Jan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      Parallel addition, i.e., addition with limited carry propagation has been so far studied for complex bases and integer alphabets. We focus on alphabets consisting of integer combinations of powers of the base. We give ...
