Določitev odklonov navpičnic iz geoidnih višin : Determination of deflection of the vertical from geoid heights [PDF]
Geodetski Vestnik, 2010 Model geoida je eden od sestavnih delov državnega koordinatnega sistema. Poleg dokaj razširjenega določanja nadmorskih višin na podlagi GNSSizmere pa model geoida zagotavlja tudi kakovostnovključitev terestričnih geodetskih opazovanj v državni ...

Advanced Engineering Materials, EarlyView.Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

Advanced Engineering Materials, EarlyView.Enhancing ultrasound transmission through an aberration layer exhibiting mismatched impedance with the surrounding medium possesses great implications in imaging and treatment. In this study, we show that a space‐coiling acoustic metamaterial with judiciously tailored structural profile can help improve impedance matching.

COMPUTING DEFLECTIONS OF TOPOLOGICALLY OPTIMIZED BEAMS
, 2023 In civil engineering, computing deflections is a fundamental step in the structural design process. However, most structural optimization codes do not directly compute or evaluate displacements in the resulting optimized structures. In that context, this

Architecture‐Driven Sensor Stability in Weft‐Knitted Engineering Textiles
Advanced Engineering Materials, EarlyView.Textile‐integrated sensor architectures are systematically compared to evaluate their electromechanical behavior under combined mechanical and environmental loading. Pocket‐based integration exhibits stable and reproducible signals, whereas tunnel‐based routing shows higher sensitivity accompanied by increased variability.
