Some solids are seldom studied analytically, unlike spheres, cylinders, and parallelepipeds. When researchers are interested in them, approximations by discretised meshes and numerical calculations are proposed. One of those is the cylindrical segment, which has applications in novel tilt-based industrial hydrometers. More specifically, the cylindrical segment has two means of being characterized: by measuring the radius, the middle height, and the cutting angle; and by measuring the radius and both the minimum height and the maximum height. In this study, one equation from the literature abou

Background Estimates of the height of patients in the intensive care unit are required to adhere to clinical guidelines for drug dosages, ventilatory support, and nutrition. The gold standard of standing height cannot be used because these patients are often unconscious and recumbent. The ability of physiotherapists or dietitians to measure height in unconscious, recumbent patients has not been evaluated.

Height and weight are parameters to identify a person, especially for a forensic. To identify height and weight is usually done manually. In addition to manually using height measuring devices and scales, you can also use information related to the foot length. There is a relationship between height and foot length can be expressed in the correlation coefficient (r) as same as for weight. Therefore, in this study, a system for measuring human height and weight based on images of the footprint is implemented on Android.

Forests in alpine mountainous regions are sensitive to global climate change. Accurate measurement of tree height is essential for forest aboveground biomass estimation. Unmanned aerial vehicle light detection and ranging (UAV-LiDAR) in tree height estimation has been extensively used in forestry inventories. This study investigated the influence of varying flight heights and point cloud densities on the extraction of tree height, and four flight heights (i.e., 85, 115, 145, and 175 m) were set in three Picea crassifolia plots in the Qilian Mountains.

Photogrammetric methods using parallaxes can be employed to measure tree heights on aerial photographs. Because it is often impossible to measure ground elevation near trees growing in dense forests, such height measurements remain prone to error. Our objective was to solve this problem by combining a stereomodel and a digital terrain model (DTM) produced by an airborne-scanning system that uses light detection and ranging (lidar). A stereopair of scanned aerial photographs was first registered to a lidar DTM. The elevation of the apex of 202 Thuja occidentalis (L.) individuals was measured by

The cost of measuring wind speed (WS) increases significantly with mast heights. Therefore, it is required to have a method to estimate WS at hub height without the need to use measuring masts. This paper examines using the Regularized Extreme Learning Machine (RELM) to extrapolate WS at higher altitudes based on measurements at lower heights. The RELM uses measured WS at heights 10-40 m to estimate WS at 50 m. The estimation results of 50 m are further used along with the measured WS at 10-40 to estimate WS at 60 m. This procedure continues until the estimation of 180 m. The RELM's performanc

In our clinic, the current preferred primary treatment regime for unilateral condylar hyperactivity is a proportional condylectomy in order to prevent secondary orthognathic surgery. Until recently, to determine the indicated size of reduction during surgery, we used a ‘panorex-free-hand’ method to measure the difference between left and right ramus heights. The problem encountered with this method was that our TMJ surgeons measured differences in the amount to resect during surgery. Other 2D and 3D method comparisons were unavailable. The aim of this study was to determine the most reproducib

In the paper the modern measurement methods of structural deformation using GOM optical measuring systems based on digital image processing were presented. First part of the work demonstrates the results of measurement of initial geometrical imperfections of steel structural elements using the Tritop optical 3D coordinate measuring machine. The method of preparation of sigma type steel beams with a height of 200 mm, a flange width of 70 mm and a wall thickness of 2 mm is presented. Afterwards, the subsequent stages of measurements and the method of reading the obtained results and their interp

Over the last decades, the role of remote sensing gained in importance for monitoring applications in precision agriculture. A key factor for assessing the development of crops during the growing period is the actual biomass. As non-destructive methods of directly measuring biomass do not exist, parameters like plant height are considered as estimators. In this contribution, first results of multitemporal surveys on a maize field with a terrestrial laser scanner are shown. The achieved point clouds are interpolated to generate Crop Surface Models (CSM) that represent the top canopy. These CSMs

Background: The ultrasonic stadiometer was originally developed as a device to measure and monitor children’s height. However, an ultrasonic stadiometer (InLab S50; InBody Co., Seoul, Korea) was used to measure adults’ height in the 2018 Korea Community Health Survey (KCHS). This study was conducted to assess the reliability and validity of the InLab S50 in adults. Methods: The study subjects were 120 adults (reliability test, n=20; validity test, n=100) who had visited a health screening center. The intra- and inter-rater reliabilities of InLab S50 were assessed using the intraclass correlati

In the field of prosthetics and orthotics, compensation is very widely used. There are various examples that how the compensation blocks play a vital role to access the shortening of the limb length and pelvic obliquity. Height is an important factor for the prosthetic cosmesis appearance, which provides the patient self-confidence to feel the equality in the society. The objective of the study was to design and develop a universal height measuring jig and find out the compensation required for the specific LLD and to decide the length from MPT to floor after initial socket fitment in case of

AbstractThe assessment of the medical conditions (liability-compliant causality) of the BK 2108 is a frequent assessment, which poses a challenge to the medical expert in orthopaedics and trauma surgery. In assessing the load-consistent damage pattern, defined changes in the intervertebral discs as well as the adjacent vertebral bodies must be comprehended in a standardised manner. Of several technical measuring methods, three practicable methods are discussed and their application explained. Thus, methods are provided which allow the medical expert to calculate the normalised relative disc he

Abstract Transition metal dichalcogenides (TMDCs) have attracted significant attention for optoelectronic, photovoltaic and photoelectrochemical applications. The properties of TMDCs are highly dependent on the number of stacked atomic layers, which is usually counted post-fabrication, using a combination of optical methods and atomic force microscopy height measurements. Here, we use photoluminescence spectroscopy, Raman spectroscopy, and three different AFM methods to demonstrate significant discrepancies in height measurements of exfoliated MoSe2 flakes on SiO2 depending on the method used.

Introduction. Malformations in kidney development and kidney diseases are accompanied with changes in their size. For kidney evaluation in clinical practice, the kidney length is the most widely used measurement, since it provides the most precise results and it is easy to perform. Recently, the measurement of relative renal length has become more preferable as it takes into account the body height. The aim of this study was to measure both the absolute and relative length of normal cadaveric kidneys according to the body height, sex and age. Material and methods. In this study, we examined 95
