Co je kostel? K počátkům šlechtických sídel českého středověku

open access: yesArcheologické Rozhledy, 2016
V diskusi o období raného středověku je z archeologického hlediska nadále třeba se vyrovnat s absencí sídel přiřaditelných ke vznikající šlechtě, z historického hlediska je neméně palčivým problémem otázka, co geneze šlechty signalizuje v rámci ...

Streamflow Monitoring at High Temporal Resolution Based on Non‐Contact Instruments and Manually Surveyed Bathymetry in a River Prone to Bathymetric Shifts

open access: yesWater Resources Research, Volume 61, Issue 4, April 2025.
Abstract This study presents a proof of concept of a reliable methodology for monitoring streamflow in a dynamic river of the Alps prone to bathymetric changes using non‐contact instruments. The method relies on water level and surface velocity radar monitoring, discharge measurements by Large‐Scale Particle Image Velocimetry (LSPIV), and topographic ...

Building a stochastic template bank for detecting massive black hole binaries

open access: yes, 2008
Coalescence of two massive black holes is the strongest and most promising source for LISA. In fact, gravitational signal from the end of inspiral and merger will be detectable throughout the Universe.

An Oversized Air‐Filled Substrate‐Integrated Waveguide Balanced‐Delta‐Port Magic‐T Power Divider/Combiner With Improved Power Handling Capability

open access: yesIET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.
This paper presents a new transmission line (TL) and power divider/combiner (PDC) design using an oversized air‐filled substrate‐integrated waveguide (OS‐AFSIW). Our approach enhances the average power handling capability and reduces conductor loss. This paper focuses on designing a balanced‐delta‐port magic‐T PDC configuration within the OS‐AFSIW that

Uncertainty Quantification in Modeling Mold Heat Transfer in Steel Continuous Slab Casting with CON1D

open access: yessteel research international, Volume 95, Issue 11, November 2024.
The accuracy of computational models depends on uncertainty of the input data. This work conducts a sensitivity analysis of the CON1D model of solidification heat transfer in a steel continuous slab‐casting mold. Results identify the parameters which are critical to defect‐relevant outputs: mold heat flux, shell thickness, surface temperature, and mold

Gravitational self-force from radiation-gauge metric perturbations

open access: yes, 2013
Calculations of the gravitational self-force (GSF) on a point mass in curved spacetime require as input the metric perturbation in a sufficiently regular gauge.

Precipitation Extremes and Their Modulation by Convective Organization in RCEMIP

open access: yesJournal of Advances in Modeling Earth Systems, Volume 16, Issue 11, November 2024.
Abstract We examine the influence of convective organization on extreme tropical precipitation events using model simulation data from the Radiative‐Convective Equilibrium Model Intercomparison Project (RCEMIP). At a given SST, simulations with convective organization have more intense precipitation extremes than those without it at all scales ...

Breakthrough design of power handling capability‐enhanced slotted oversized substrate‐integrated waveguide power divider/combiner considering corona and thermal effects

open access: yesIET Microwaves, Antennas &Propagation, Volume 18, Issue 10, Page 779-790, October 2024.
A new sled‐power divider/combiner (PDC) based on an oversized substrate‐integrated waveguide (OS‐SIW) is analysed and designed for improving the power handling capability. The measured results of the fabricated PDC showcase a range of desirable features.
