Development of Laterally Graded X‐Ray Multilayer Optics

open access: yesAdvanced Materials Technologies, EarlyView.
This work presents the development of laterally graded X‐ray multilayer optics with both constant and variable lateral gradients. By precisely controlling substrate speed profiles and mask design, these multilayers achieve highly accurate lateral gradients and excellent sagittal thickness uniformity, making them ideal for spectroscopy application at ...

A thermodynamic diagnostic model for the atmosphere. Part II: The general theory and its consequences

open access: yesMeteorologische Zeitschrift, 1993
A diagnostic model for an atmospheric column is presented. It is based upon the averaged equations for moisture and heat. The averaging generates sub-gridscale vertical fluxes of rain, moisture and heat as functions of pressure p. These are the unknowns;

Bower ratio-energy balance associated errors in vineyards under dripping irrigation Erros associados pela razão de bowen ao balanço de energia em parreirais sob irrigação por gotejamento

open access: yesRevista Brasileira de Meteorologia, 2007
This study was conducted at the Bebedouro Experimental Station in Petrolina-PE, Brazil, to evaluate the errors associated to the application of the Bowen ratio-energy balance in a 3-years old vineyard (Vitis vinifera, L), grown in a trellis system ...

Development of High‐Performance Multilayer Monochromators

open access: yesAdvanced Optical Materials, EarlyView.
Detailed insights into the optical and multilayer design of Double Multilayer Monochromators (DMM) are presented and fully characterized, including key optimization strategies and solutions to fabrication challenges. By integrating in‐house Ion Beam Figuring and a high uniformity multilayer coating process, the developed DMMs achieve high reflectivity,

A subgroup formula for f-invariant entropy

open access: yes, 2012
We study a measure entropy for finitely generated free group actions called f-invariant entropy. The f-invariant entropy was developed by Lewis Bowen and is essentially a special case of his measure entropy theory for actions of sofic groups.
