Probabilistic Failure Analysis of SiC‐CMC/Nb Fuel Claddings Under Loss‐Of‐Coolant Accident Conditions

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
A numerical framework leveraging finite element analysis is established to examine the thermomechanical behavior and burst safety of a novel accident‐tolerant fuel (ATF) cladding design. This design incorporates a thin niobium (Nb) liner positioned between two layers of silicon carbide ceramic matrix composites (SiC‐CMC).

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 ...

Exceptional points in a passive strip waveguide

open access: yesNanophotonics, Volume 14, Issue 8, Page 1301-1309, April 2025.
Abstract Exceptional points (EPs) in non‐Hermitian systems have attracted significant interest due to their unique behaviors, including novel wave propagation and radiation. While EPs have been explored in various photonic systems, their integration into standard photonic platforms can expand their applicability to broader technological domains.

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

Nový hrad u Kunratic v Praze : výzkum a obnova zanikající hradní stavby

open access: yesArchaeologia Historica, 2015
Nový hrad u Kunratic v Praze je zřícenina původně královského hradu vystavěného na počátku druhého desetiletí 15. století z podnětu českého a římského krále Václava IV. Hrad neměl dlouhého trvání. Již v roce 1421 byl dobyt a poničen vojsky husitů.

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 ...

Dva opevněné objekty u Bernartic (okres Písek) : k otázce jejich vztahu, funkční interpretace a souvislostí

open access: yesArchaeologia Historica, 2015
Dva zaniklé opevněné objekty na katastru obce Borovany, okr. Písek, představují cenné archeologické lokality založené v období samého počátku budování vrcholně středověkých opevněných objektů v Čechách. Obě lokality, jejichž počátky pravděpodobně spadají
