This paper proposes a new method to improve the three-dimensional (3D) high precision optical surface measurement using a non-contact laser focusing probe. Herein, the displacement or the profile of the tested surface can be obtained by measuring the driving voltage curve to the piezoelectric translator's (PZT) expansion distance.

The objective of the present study is to enhance the hovering efficiency of a UAV helicopter with a spherical fuselage under the effects of the fuselage size (Rf/R) and the distance between the fuselage and rotor (Hm/R), where R is the rotor radius. The RANS method combined with the k-ε turbulent model is used to model the airflow through the helicopter. The numerical model mentioned was well validated by comparing it with the results obtained in the literature.

This study examined the effect of DEM resolutions (12.5 m, 30m, 50m, 70m, and 90m) on the accuracy of landslide susceptibility maps in Laocai city, Laocai province. The eight causative factor maps, including elevation, slope, slope aspect, distance to drainage, distance to roads, lithology, distance to faults, and rainfall, were produced.

The electronic states of FeSin −/0/+ (n = 1-2) clusters have been investigated with DFT, CASPT2, and DMRGCASPT2 methods. By using relatively large active spaces, the DMRG-CASPT2 method is found to provide highly accurate relative energies for the various relevant electronic states. Leading configurations, bond distances, harmonic vibrational frequencies, and relative energies for the low-lying states of the title clusters are reported.

The purpose of this paper is to determine the relevance of turning the camera on or off during distance learning as an argument for active or passive student participation. Seventy-five (75) students participated in the study and were divided into five groups (1-5) according to teaching method (i.e., synchronous instruction online with camera (1) and without camera (2), synchronous transmission of the recording online with camera (3) and without camera (4) and received the online instruction (5)) only.

The greatest impact on the cadastral value of land plots is the distance to the capital of the Russian Federation and the land area. The influence of the coefficient of the length of the land plot on its cadastral value in all built specifications was not confirmed. The quality of the results was tested using Fisher test, student test, regression equation specification error test (RESET), testing of regression residues on heteroskedasticity and autocorrelation (White test, Breusch-Pagan test).

Spatial patterns of forest trees have been long recognized as evidences of underlying biological processes within forests. We used point pattern analysis methods and process-based models to detect the demography and dynamics of trees in a primary rainforest stand. A fully mapped 1-ha plot was investigated in the tropical rain forest of Cuc Phuong National Park. Trees were stem-mapped, diameter-measured at breast height and classified into species.

Ebook "Constitutional dynamic chemistry" focuses on constitutional methods for understanding and controlling such upscale propagation of structural information. These methods show potential to impose further precise order at the mesoscale and to discover new routes to obtain highly ordered ultradense arrays over macroscopic distances.

The family Echinostomatidae includes four genera, Echinostoma, Hypoderaeum, Echinoparyphium, and Artyfechinostomum, which are of public epidemiological and pathogenic importance. The morphological similarity of species requires differentiating methods, and the use of molecular genetic markers is mainly encountered.

MDS (maximum distance separable) matrices are ones that come from MDS codes that have been studied for a long time in error correcting code theory and have many applications in block ciphers. To improve the security of block ciphers, dynamic block ciphers can be created. Using MDS matrix transformations is a method used to make block ciphers dynamic.

In this article, we also ultilize ceiling mounted AprilTags for our AMR application in indoor environment. The advantage of AprilTags is their invariance to uncertainty of the environment such as lightning conditions, providing robust pose measurements with a fairly large range of measuring distances from the camera to fiducial markers.

In this paper, we report in detail the compressive strength of wet granules under a diametrical compression test by means of the discrete element simulations. The numerical method is coupled with the capillary cohesion law which is enhanced by the cohesive forces between grains having a gap not exceeding a rupture distance.

The study "Estimation of apartment value using the hedonic pricing method: The case in District 7, Ho Chi Minh city, Vietnam" aims to develop a mathematical model to evaluate the value of apartments in District 7, Ho Chi Minh city. This paper using the hedonic pricing model by a linear regression method. The results revealed that the environment, grading of condominiums, the distance to central, area, view, floor level are the primary descriptors of apartment value in the study area.
