Abstract Radiative surface properties play a critical role in the design, analysis and optimization of solar thermal systems. Cavity receivers increase efficiency solar-thermal energy systems through cavity effect. The effect refers to increased absorption radiation due multiple reflections within cavity. Apparent radiative characterize effective interactions passing an imaginary covering aperture. In this study, we investigate extent which apparent emissivity with non-uniform temperature...
Abstract Peptide cyclization has dramatic effects on a variety of important properties, enhancing metabolic stability, limiting conformational flexibility, and altering cellular entry intracellular localization. The hydrophilic, polyfunctional nature peptides creates chemoselectivity challenges in macrocyclization, especially for natural sequences without biorthogonal handles. Herein, we describe gaseous sulfonyl chloride derived reagent that achieves amine–amine, amine–phenol, amine–aniline...
We invert the Fredholm equation representing light scattered by a single spherical particle or distribution of particles to obtain size function and refractive index. solution expanding as linear combination set orthonormal basis functions. The functions is composed Schmidt-Hilbert eigenfunctions supplemental functions, which have been orthogonalized with respect using Gram-Schmidt orthogonalization procedure. use orthogonality properties eigenvectors kernel covariance matrix that minimizes...
Thermal management systems for space equipment commonly use static solutions that do not adapt to environmental changes. Dynamic control of radiative surface properties is one way respond changes and increase the capabilities spacecraft thermal systems.

This work explores impact changing projected surface area and varying apparent properties on net an accordion fold comprised V-grooves. The tessellation is obtained by thermal energy balance at openings with cavities given function various parameters. Results analytical model are experimentally confirmed. An tessellation, constructed stainless-steel shim...
Thermal tomography is a nondestructive method for detecting inhomogeneities in material by localizing variations its thermal conductivity. Based on finite element discretization of the heat conduction equation, we obtain set equations that relate conductivity medium to temperature measurements surface medium. We investigate use both linearization and regularization technique randomized search procedure based genetic algorithm invert this equations. found tradeoff exists between accuracy...
A new data extract toolkit known as EPICExtract Plug-In Components Toolkit has been designed and implemented to create surface extracts in situ via the TURBO CFD code. New FieldView (eXDB) with a Proper Orthogonal Decomposition (POD) reduced order model were implemented, visualized analyzed using prototype version of post-processor FieldView. Benchmarks show that EPIC POD have some memory computational cost overhead may be mitigated by overall user workflow reduction files saved disk. In...
Measurements of the light scattered by a sample contain information regarding physical properties sample. Laser light-scattering measurements can be made unobtrusively in environments that are inaccessible to other types measurements, so laser techniques have become an important tool aerosol research. The primary difficulty associated with using determine particle is inverting or extracting desired from measurements. In this study we use 15-channel polar nephelometer measure patterns...
This paper describes the application of reduced-order modeling techniques in simulation conjugate heat transfer processes. In a model (ROM), dominate features system are represented using limited number orthonormal basis vectors, which extracted from database containing descriptions system. Interpolating methods then used to calculate expansion coefficients that allow representation as linear combinations vectors. Evidence accuracy and computational savings achieved technique is presented...

When short length exposed high temperature environment, at can be inferred using standard two-color approach. If, however, more than elevated temperatures, by will result in erroneous measurements. This paper presents experimental results that show it possible use additional spectral measurements eliminate...
