We implement finite-difference time-domain (FDTD) method to simulate the optical properties of highly polarized InGaN light emitting diodes (LEDs) coupled with metallic grating structure. The Purcell factor (Fp), light extraction efficiency (LEE), internal quantum efficiency (IQE), external quantum efficiency (EQE), and modulation frequency are calculated for different polarized emissions. Our ...

1. Introduction The Cross-track Infrared Sensor (CrIS) [1] is one of the key instruments for the National Polar-Orbiting Environmental Satellite System (NPOESS) [2]. As a Michelson interferometer, CrIS measures atmospheric emission spectrum in the infrared, which is to be used to produce the vertical temperature and moisture profiles of the Earth's atmosphere. The first Flight Module (FM1) of C...

ZnO nanowire (NW) visible-blind UV photodetectors with internal photoconductive gain as high as G approximately 108 have been fabricated and characterized. The photoconduction mechanism in these devices has been elucidated by means of time-resolved measurements spanning a wide temporal domain, from 10-9 to 102 s, revealing the coexistence of fast (tau approximately 20 ns) and slow (tau approxim...

To improve point-of-care quantification using microchip capillary electrophoresis (MCE), the chip-to-chip variabilities inherent in disposable, single-use devices must be addressed. This work proposes to integrate an internal standard (ISTD) into the microchip by adding it to the background electrolyte (BGE) instead of the sample-thus eliminating the need for additional sample manipulation, mic...

With objective of analyzing the mechanical behavior of the internal fixators of spine and of the bony structure, the pieces and the group were made (it structures bony x internal fixator) with the aid a software of solid modeling. The materials used in the rehearsals had been the titanium, now in the market and a castor oil polyurethane destined to the development of you implant bony.

We develop a translation from PDDL2.2 into NDDL, the language used by NASA’s EUROPA2 planning system. Starting from a PDDL2.2 description of the world based on propositions and operators, we generate an NDDL model that features timelines, activities and compatibilities. The relevance of the translation is twofold. From a theoretical point of view, the translation is interesting since it transfo...

The disease Arshas or Hemorrhoids is as old as mankind. Still, a large proportion of the world’s population is troubled by Hemorrhoids. This may be perhaps to the inconsistency of the human diet and to the social obligations demanded by civilization. This disease is generally not a threat of life, but causes considerable discomfort, enforced bed rest, absence from work with consequent economic ...

Intermaxillary fixation (IMF) is an essential guide to optimize the reduction and fixation of most facial fractures associated with occlusal alterations. To allow IMF, nasotracheal intubation is used in most cases. When nasotracheal intubation is not possible, a tracheostomy may be indicated, but this carries significant morbidity. Submental endotracheal intubation allows IMF to be used without...

This paper presents an overview of the experiment INTIMATE96, carried out in June 1996 on the continental shelf off the coast of Portugal and discusses the effects of internal tides on the acoustic propagation. A towed broadband acoustic source and a 4-hydrophone vertical array were used. Acoustic data were collected for 5 days, including legs where the source ship was moving and legs with the ...
