Grayscale Values in Cone Beam Computed Tomography: Scope and Limitations
(Facultad de Odontología. Universidad de Costa Rica, 2021)
Abruptly autofocusing beams from phase perturbations having forced symmetry
(Optical Society of America, 2019-08)
A controllable manipulation of the energy distribution of caustic beams possessing rectangular symmetry is presented. The beams are designed from the spectral phase by adding a linear and/or quadratic perturbation having ...
Ultra-long light sheets via curved beam intercrossing
(Optical Society of America, 2020-07-31)
An approach to yield a planar light sheet with thickness below the Abbe’s diffraction limit over ultra-long propagation distances is presented. Such features emerge by an induced interference of the fields associated to ...
Experimental analysis on the combined effects of corrosion and fatigue in reinforced concrete beams
(ANTAC - Associação Nacional de Tecnologia do Ambiente Construído, 2019)
Comportamento estrutural de vigas mistas de aço e concreto com protensão externa
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECiv, 2013-07-11)
This report investigates the structural behavior, procedures for analysis and design of externally prestressed steel-concrete composite beams. Based upon the requirements outlined in ABNT NRB 8800:2008 for conventional ...
Imagen de hipertrofia bilateral del proceso coronoides mandibular a través de la tomografía computarizada cone-beam
(2012)
The hypertrophy of the mandibular coronoid process is a rare condition, progressive and of unknown etiology, characterized by the over development of the coronoid process determining their size increased, resulting in ...
Limits of the paraxial approximation in laser beams
(Optical Society of America, 2007-04-15)
The validity of the paraxial approximation for laser beams in free space is studied via an integral criterion based on the propagation invariants of Helmholtz and paraxial wave equations. This approach allows one to determine ...
