    • EXPERIMENTAL CHARACTERIZATION OF AN OVERDENSE PLASMA IN A COMPACT ION SOURCE 

      Autor: Castro , Giuseppe; Mascali , David; Romano , Francesco Paolo; Altana , Carmen; Caliri , Claudia; Celona , Luigi; Di Giugno , Rossella; Gambino , Nadia; Lanaia , Davide; Miracoli , Rosalba; Musumarra , Agatino; Neri , Lorenzo; Torrisi , Giuseppe; Gammino , Santo
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      Electron Cyclotron Resonance Ion Sources (ECRIS) are compact plasma-based machines able to feed particle accelerators with high intensity beams of multi-charged ions. ECRIS plasmas are density-limited, since they are ...
    • DECENTRALIZED MULTIROBOT PLANNING TO EXPLORE AND PERCEIVE 

      Autor: Matignon , Laetitia; Jeanpierre , Laurent; Mouaddib , Abdel-Illah
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      In a recent French robotic contest, the objective was to develop a multi-robot system able to autonomously map and explore an unknown area while also detecting and localizing objects. As a participant in this challenge, ...
    • COMPARISON OF EXPLORATION STRATEGIES FOR MULTIROBOT SEARCH 

      Autor: Kulich , Miroslav; Juchelka , Tomáš; Přeučil , Libor
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      Searching for a stationary object in an unknown environment can be formulated as an iterative procedure consisting of map updating, selection of a next goal and navigation to this goal. It finishes when the object of ...
    • COMPARISON OF CLASSICAL AND INTERACTIVE MULTIROBOT EXPLORATION STRATEGIES IN POPULATED ENVIRONMENTS 

      Autor: Kalde , Nassim; Simonin , Olivier; Charpillet , François
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      Multi-robot exploration consists in coordinating robots for mapping an unknown environment. It raises several issues concerning task allocation, robot control, path planning and communication. We study exploration in ...
    • POLYMERS CONTAINING Cu NANOPARTICLES IRRADIATED BY LASER TO ENHANCE THE ION ACCELERATION 

      Autor: Cutroneo , Mariapompea; Torrisi , Lorenzo; Mackova , Anna; Velyhan , Andriy
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      Target Normal Sheath Acceleration method was employed at PALS to accelerate ions from laser-generated plasma at intensities above 1015 W/cm2. Laser parameters, irradiation conditions and target geometry and composition ...
    • GALACTIC CENTER MINISPIRAL: INTERACTION MODES OF NEUTRON STARS 

      Autor: Zajacek , Michal; Karas , Vladimir; Kunneriath , Devaky
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      Streams of gas and dust in the inner parsec of the Galactic center form a distinct feature known as the Minispiral, which has been studied in radio waveband as well as in the infrared wavebands. A large fraction of the ...
    • SIMULATION OF HEAT TRANSPORT AT THE COOLING OF THE SUGAR SOLUTION IN A RECUPERATION EXCHANGER 

      Autor: Brestovič , Tomáš; Čarnogurská , Mária; Příhoda , Miroslav; Kubík , Michal
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      The paper describes a mathematical model of the cooling process of a highly concentrated sugar solution in an exchanger with a specifically shaped heat exchanging surface of the cooling panels. An analysis of the individual ...
    • EFFECT OF THE FLOW FIELD DEFORMATION IN THE WIND TUNNEL ON THE AERODYNAMIC COEFFICIENTS 

      Autor: Maturkanič , Dušan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      The flow field quality has a principal signification at wind tunnel measurement. The creation of the flow field of air by fan leads to the rotation of entire flow field which is, moreover, deformed at the bends of the wind ...
    • HYDROGENATED TARGETS FOR HIGH ENERGY PROTON GENERATION FROM LASER IRRADIATING IN TNSA REGIME 

      Autor: Torrisi , Lorenzo; Cutroneo , Mariapompea; Ullschmied , Jiri
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      Polyethylene-based thin targets were irradiated in high vacuum in the TNSA (Target Normal Sheath Acceleration) regime using the PALS laser facility. The plasmais produced in forward direction depending on the laser irradiation ...
    • ANALYSIS OF TRANSONIC FLOW PAST CUSPED AIRFOILS 

      Autor: Stodůlka , Jiří; Šafařík , Pavel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      Transonic flow past two cusped airfoils is numerically solved and achieved results are analyzed by means of flow behavior and oblique shocks formation.Regions around sharp trailing edges are studied in detail and parameters ...
    • AN EXPERIMENTAL INVESTIGATION INTO MOISTUREINDUCED EXPANSION OF PLASTERS 

      Autor: Sovják , Radoslav
