44 check point coordinates were measured to compare the aerotriangulated value of the points to their observed position in the mosaic to ensure the data meets horizontal accuracy requirement. The reported horizontal accuracy is 0.039 meter RMSE.
Aerial Photography Capture: A twin-engine aircraft with an on-board Intergraph frame-based digital mapping camera (DMC) was used to capture individual frames of imagery. The position and orientation of the aircraft was recorded at each exposure with the on-board global positioning system (GPS) and inertial measuring unit (IMU).
Orthorectification Process: Inpho OrthoMaster software was used to process the imagery to remove systematic and terrain distortions while also georeferencing it. The resulting output files were output with a ground sample distance (GSD) of 0.075 m.
Tile Review: The mosaicked tiles were each individually panned through and errors/blemishes in seamline generation and color balance are removed by manual methods. This data set was also compared to imagery previously collected, processed, and delivered to the client in order to shift the overall color cast of the current imagery to better resemble the legacy data.
Header Creation and Horizontal Checks: The mosaic tiles have their georeferencing information assigned into the headers of the tiles creating full geotiffs. The tiles are then checked for horizontal positioning utilizing ground control.
N2 - The human neuromuscular system can be seen as a versatile and extremely adaptive actuator. Through co-contraction and reex modulation, the properties of the neuromuscular system can be modified, leading to a change in movement response to externally applied forces. These properties are normally expressed in the form of the neuromuscular admittance. In a series of standard tasks, the force-, relax-, and position-task admittance of the neuromuscular system can be identified. However, the test signals used in these tasks can also limit the range of reex adaptation possible and wrong choice can create a phenomenon analogous to cross-over regression in manual control tasks, and force the human to use only a limited range of the possible reex adaptation. This paper presents a systematic investigation, through a model study, of the inuence of test signals on the range of reex adaptation. For this, criteria for test signal acceptability have been developed. The method is applied to the currently used test signals consisting of a high and a low shelf, and enables the selection of the high shelf bandwidth.

To assess the effects of manual hyperinflation, performed with a manual resuscitator with and without the positive end-expiratory pressure valve, on the respiratory function of preterm newborns under mechanical ventilation.
Cross-sectional study of hemodynamically stable preterm newborns with gestational age of less than 32 weeks, under mechanical ventilation and dependent on it at 28 days of life. Manual hyperinflation was applied randomly, alternating the use or not of the positive end-expiratory pressure valve, followed by tracheal aspiration for ending the maneuver. For nominal data, the two-tailed Wilcoxon test was applied at the 5% significance level and 80% power.
Lung volumes increased when performing the maneuver with and without the valve, with a significant difference in the first minute after aspiration. There was a significant difference in expiratory resistance between the time-points A5 (before the maneuver) and C1 (immediately after tracheal aspiration) in the first minute after aspiration within each maneuver.
Avaliar as repercusses da hiperinsuflao manual, realizada com ressuscitador manual com e sem vlvula de presso positiva expiratria final, sobre a funo respiratria de recm-nascidos pr-termo em ventilao mecnica.
Estudo transversal com recm-nascidos pr-termo com idade gestacional inferior a 32 semanas, em ventilao mecnica e dependentes desta aos 28 dias de vida, estveis hemodinamicamente. A hiperinsuflao manual foi aplicada de forma randomizada, alternando o uso ou no uso da vlvula de presso positiva expiratria final, seguida de aspirao intratraqueal finalizando a manobra. Para os dados nominais, foi aplicado o teste de Wilcoxon com hiptese bilateral ao nvel de significncia de 5% e poder de teste de 80%.
Os volumes pulmonares aumentaram na manobra com e sem vlvula, havendo diferena significativa no primeiro minuto aps a aspirao. Houve diferena significativa na resistncia expiratria entre os momentos A5 (antes da manobra) e C1 (imediatamente aps aspirao intratraqueal) no primeiro minuto aps a aspirao dentro de cada manobra.
Improved perinatal care, the use of antenatal corticosteroids, administration of exogenous surfactant and new ventilatory strategies have contributed to the increased survival of increasingly premature children and those with very low birth weight, thereby increasing the number of preterm newborns needing mechanical ventilation.(11 Godoy AC, Vieira RJ, De Capitani EM. Alterations in peak inspiratory pressure and tidal volume delivered by manually operated self-inflating resuscitation bags as a function of the oxygen supply rate. J Bras Pneumol. 2008;34(10):817-21.

Patients under mechanical ventilation present functional changes in the mucociliary system caused by a set of determinant factors, such as the presence of a tracheal tube, the use of high oxygen concentrations, lower airway injury induced by tracheal aspiration and inadequate humidification of the mechanical ventilation system.(44 Judson MA, Sahn SA. Mobilization of secretions in ICU patients. Respir Care. 1994;39(3):213-26.,55 Prez BF, Mndez GA, Lagos RA, Vargas MSL. [Mucociliary clearance system in lung defense]. Rev Med Chil. 2014;142(5):606-15.) Excessive mucus production, together with the abovementioned factors, increases the risk of sputum retention, lung infection and atelectasis, which are common complications in patients under invasive respiratory support. The impairment of oxygenation due to an intrapulmonary shunt, changes in the ventilation-perfusion ratio, and increased pulmonary vascular resistance can cause lung injury. Sputum retention in the airway provides an ideal environment for colonizing microorganisms, resulting in pneumonia, and a consequent reduction in lung compliance.(44 Judson MA, Sahn SA. Mobilization of secretions in ICU patients. Respir Care. 1994;39(3):213-26.

Ventilator versus manual hyperinflation in clearing sputum in ventilated intensive care unit patients. Anaesth Intensive Care. 2012;40(1):142-9.)
The application of physical therapy techniques can provide hemodynamic and respiratory stability to these patients. The use of respiratory physical therapy techniques that cause acceptable hemodynamic changes with prolonged pulmonary effects is highly desirable, but more studies are needed in this specific population for improving the approach and treatment of newborns.(1010 Berney S, Denehy L. A comparison of the effects of manual and ventilator hyperinflation on static lung compliance and sputum production in intubated and ventilated intensive care patients.

The use of self-inflating bag with the positive end-expiratory pressure (PEEP) valve is desirable for preventing and minimizing the deleterious effects caused by disconnecting the patient from the mechanical ventilator.(1212 Choi JS, Jones AY.
