RISThe Rodrigues Equations for the Composition of Finite Rotations: A Simple Ab Initio Derivation and Some Consequences
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The wellknown Rodrigues' equations for the composition of two finite rotations were introduced in 1840 without a detailed derivation. Although later derivations are available, the one presented here is very simple, is based ...
Parametric Analysis of the Fixed Mirror Solar Concentrator for Medium Temperature Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: adapted for integration onto building roofs. An optical raytracing analysis of its geometry was presented in a previous paper (Pujol Nadal and Martأnez Moll, 2012, “Optical Analysis of the Fixed Mirror Solar Concentrator by Forward RayTracing Procedure...
Periodic Solutions in Low-Dimensional Climatic Models
Publisher: American Meteorological Society
Abstract: Classic climatic models use constitutive laws without any response time. A more realistic approach to the natural processes governing climate dynamics must introduce response time for heat and radiation fluxes. Extended ...
Runaway Greenhouse Effect in a Semigray Radiative–Convective Model
Publisher: American Meteorological Society
Abstract: The effects of the nongray absorption (i.e., atmospheric opacity varying with wavelength) on the possible upper bound of the outgoing longwave radiation (OLR) emitted by a planetary atmosphere have been examined. This ...
Optical Analysis of the Fixed Mirror Solar Concentrator by Forward Ray-Tracing Procedure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fixed mirror solar concentrator (FMSC) is a mobile focus concentrator whose design emerged in the 1970s in an effort to reduce electricity production costs in solar thermal power plants. ...
Transverse Reinforcement for Columns of RC Frames to Resist Earthquakes
Publisher: American Society of Civil Engineers
Abstract: An approximate formulation to determine the amount of transverse reinforcement for columns of reinforced concrete (RC) frames in seismic areas is presented. It is based on observations that suggested that the main function ...
Axial Failure of Reinforced Concrete Columns Damaged by Shear Reversals
Publisher: American Society of Civil Engineers
Abstract: Results from tests on eight full-scale RC columns with ties with large spacing (
Impact of Multialtimeter Sea Level Assimilation in the Mediterranean Forecasting Model
Publisher: American Meteorological Society
Abstract: In this article the impact of multisatellite altimeter observations assimilation in a high-resolution Mediterranean model are analyzed. Four different altimeter missions [Jason-1, Envisat, Ocean Topography Experiment ...
Degradation of Radar Reflectivity by Cloud Attenuation at Microwave Frequency
Publisher: American Meteorological Society
Abstract: The main object of this paper is to emphasize that clouds?the nonprecipitating component of condensed atmospheric water?can produce a strong attenuation at operational microwave frequencies, although they present a low ...
Incidence-Angle- and Wavelength-Resolved Ray-Tracing Simulations of a Linear Fresnel Collector Using the In-House Software otsun
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The set of optical models that is implemented in ray-tracing software determines the accuracy of its output. A sensitivity analysis was carried out using a powerful in-house program, which provides a large number of surface ...
