With each generation of technology, computers become even more capable of rendering objects with an ever increasing number of polygons. As a result, the desire to add more details to a 3D model increases as well. Among the many tools provided by computer graphics software that an artist has at...
Raman scattering can be a significant contributor to the emergent radiance spectrum from the surface ocean. Here, we present an analytical approach to directly estimate the Raman contribution to remote sensing reflectance, and evaluate its effects on optical properties estimated from two common semi analytical inversion models. For application of...
The construction industry is one of the largest sectors in the U.S. economy, yet little is known about the
key macroeconomic parameters that affect its industry’s structure and performance. The main objectives
of this research are 1) to analyze the macroeconomic performance of construction industry as a whole and
at...
We are convinced that the combination of data-parallel languages and MIMD hardware can make an important contribution to high speed computing. The data-parallel paradigm is a natural way to solve a large number of problems arising in science and engineering. Data-parallel programs are easier to design, implement, and debug than...
Rockfishes, Sebastes spp.. were the most numerous and speciose fishes seen during 16 submersible dives from 64 to 305 m depth in the vicinity of Heceta Bank off the coast of Oregon. Dense schools of juvenile rockfishes and large yellowtail rockfish, S. flavidus, were observed only over rocky, high relief...
This paper discusses the fundamentals of a novel hybrid method to synthesize oxide dispersion strengthened (ODS) 304 L stainless steel (SS) alloy using a modified laser powder bed fusion (LPBF) machine. Previously, ODS metal matrix composites have been produced by LPBF via ball-milling, which is expensive to scale. Here, we selectively...
Oxide dispersion strengthened (ODS) alloys exhibit superior mechanical properties due to the presence of nano-sized thermally stable oxide particles. However, manufacturing of ODS alloys is very complex and composed of numerous time consuming steps such as mechanical alloying, which is one of the main barriers toward the widespread application of...
The role of volumetric energy density on the microstructural evolution, texture and mechanical properties of 304L stainless steel parts additively manufactured via selective laser melting process is investigated. 304L is chosen because it is a potential candidate to be used as a matrix in a metal matrix composite with nanoparticles...
The Alaska recreational charter boat sector has undergone significant change in recent years due in part to several regulatory changes in the management of the Pacific halibut sport fishery, including a limited entry program, harvest controls specific to the charter sector, and a Catch Sharing Plan (CSP) implemented during 2014....
The authors demonstrate the generation of multicycle narrow-bandwidth terahertz pulses in periodically inverted GaAs structures using optical rectification of 2 μm, 100 fs pump pulses. Three different types of orientation-inverted samples are employed: optically contacted multilayer, orientation-patterned, and diffusion-bonded GaAs. The terahertz pulses are characterized by two-color (pump at 2...
