Research into rail side wearing on curves [PDF]
Transport, 2003 Factors influencing rail side wearing in the curves are described in the article. All of them are divided into uncontrolled, partially controlled and controlled. An experiment was carried out on Lithuanian railway line curves.

Application of modern geodetic tools in the operation of railway reconstructions [PDF]
E3S Web of Conferences, 2021 This research considers the survey of the circular curve of the operating railway using an electronic total station, which determines the coordinates of points on the curve and calculates the coordinates of the main points of the circular curve. The goal

Teaching a culture of care: Why it matters
Revista de Bioética y Derecho, 2021 The use of animal in biomedical research remains a critical compromise. Research and higher education institutions play a major role in educating on the use of animal and such training is expected to translate into the development of a culture of care ...

Capturing information on curves and surfaces from their projected images
International Journal of Mathematics for Industry, 2020 Obtaining complete information about the shape of an object by looking at it from a single direction is impossible in general. In this paper, we theoretically study obtaining differential geometric information of an object from orthogonal projections in ...

Measuring the intensity of conflicts in conservation
Conservation Letters, 2021 Conflicts between the interests of biodiversity conservation and other human activities pose a major threat to natural ecosystems and human well‐being, yet few methods exist to quantify their intensity and model their dynamics.

Continuous Tracking of Foot Strike Pattern during a Maximal 800-Meter Run
Sensors, 2021 (1) Background: Research into foot strike patterns (FSP) has increased due to its potential influence on performance and injury reduction. The purpose of this study was to evaluate changes in FSP throughout a maximal 800-m run using a conformable ...

Visual Perception: To Curve or Not to Curve [PDF]
Current Biology, 2018 A popular new illusion shows that the apparent curvature of sinusoidal contours depends on contrast and background luminance. We suggest that the illusion is driven by segmentation mechanisms of human vision, which isolate the contours into smaller segments, some which approximate straight lines, others curves.

Coloring Curves that Cross a Fixed Curve [PDF]
Discrete & Computational Geometry, 2018 We prove that for every integer $t\geq 1$, the class of intersection graphs of curves in the plane each of which crosses a fixed curve in at least one and at most $t$ points is $χ$-bounded. This is essentially the strongest $χ$-boundedness result one can get for this kind of graph classes.

Horticulturae, 2021 The accurate modeling of wolfberry plant morphology is the basis for theoretical and simulation analyses of the wolfberry picking process. The curved shape of the fruit branches makes it challenging to model Lyciumbarbarum (wolfberry) plants.
