Lane Surface Identification Based on Reflectance using Laser Range Finder
In striving to achieve autonomous navigation the problem of guidance is a major difficulty faced by fully autonomous vehicle. In this paper, the authors focus on unconventional methods of identifying lane markings on a ...
Argon laser for treatment of benign eyelid tumors
Small lesions located in the skin might be treated using the laser system. The purpose of this is to report the therapy of benign eyelid tumors using argon laser. Forty-four benign eyelid tumors were treated using argon ...
Intrapulpar temperature during continuous CO2 laser irradiation in human molars: An in vitro study
To establish safety parameters, we in vitro studied the increase in intrapulpal temperature caused by the use of a cw CO2 laser. A thermistor was implanted in the inner part of the pulpal chamber of 25 human lower third ...
Laser scanner based heading angle and distance estimation
Towards autonomous vehicle navigation the problem of guidance is a major difficulty faced by fully autonomous vehicle. This paper proposes a new method to estimate the heading angle for safe autonomous navigation purpose. ...
Estudo das ondas guiadas em lasers de semicondutor
Effect of the Nd:YAG and the Er:YAG laser on the adhesive-dentin interface: a scanning electron microscopy study
(Mary Ann Liebert, Inc.Porto Alegre, 2010)
Objective: This study analyzed the adhesive-dentin interface when Nd:YAG and Er:YAG lasers were applied on dentin. Background data: Lasers applied on dentin cause morphological changes of this tissue. As the adhesive systems ...
A 12-month follow-up of hypopigmentation after laser hair removal
Introduction: Laser hair removal is becoming an increasingly popular alternative to traditional methods such as shaving, waxing, among other methods. Semiconductor diode lasers are considered the most efficient light sources ...
Avaliação histológica e morfológica da pele de ratos adultos submetidos à ação de um laser de CO2 fracionado aplicado com três diferentes parâmetros = Histological and morphological skin evaluation of adult rats treated with a fractional CO2 laser applied at three different settingsHistological and morphological skin evaluation of adult rats treated with a fractional CO2 laser applied at three different settings
Photogrammetric refinement of laser-based building roof contours
In this paper a photogrammetric method is proposed for refining 3D building roof contours extracted from airborne laser scanning data. It is assumed that laser-derived planar faces of roofs are potentially accurate, while ...
