A new aerial platform has risen recently for image acquisition, the Unmanned Aerial Vehicle (UAV). This article describes the technical specifications and configuration of a UAV used to capture remote images for early season site- specific weed management (ESSWM). Image spatial and spectral properties required for weed seedling discrimination were also evaluated. Two different sensors, a still ...

introduction: herpes labialis is important in dentistry because of its high prevalence. herpes simplex virus (hsv) is responsive to treatment and infection control methods help protect patients and dental personnel. due to high levels of stress in the flight crew this study evaluated the prevalence of recurrent herpes labialis in the personnel of an airline company. materials and methods: in th...

in this paper a new guidance technique for ballistic missiles and launch vehicles is proposed. generally the lambert guidance is used to generate missile nominal (correlated) parameters through powered flight to put it in a ballistic flight path. because of uncertainties and undesired factors, the nominal position and velocity obtained by lambert technique need to be followed in actual flight. ...

OBJECTIVE To identify whether flight training activities cause postural changes in cadets and pilots of the Brazilian Air Force Academy (AFA). METHODS Eighty subjects were assessed through photographic images in anterior and right side views. Four groups of cadets (n=20 per group) divided according to the year since enlistment and a fifth group of fifteen pilots from the Air Demonstration Squ...

Recently, analysis and decision-making based on spatiotemporal unmanned aerial vehicle (UAV) high-resolution imagery are gaining significant attention in smart agriculture. Constructing a dataset requires multiple UAV image mosaics taken at different times. Because the weather or flight trajectory is subject to change when images taken, typically unaligned. This paper proposes two-step approach...

A transfer alignment is used to initialize, align, and calibrate a SINS(Slave INS) using MINS(Master in motion. This paper presents an airborne with velocity azimuth matching estimate inertial sensor biases under the wing flexure influence. study also considers lever arm, time delay relative orientation between MINS SINS. The traditional only uses matching. In contrast, this utilizes prevent di...
