How Indonesian Students Use the Polya’s General Problem Solving Steps
Southeast Asian Mathematics Education Journal, 2018 General problem-solving steps consist of understanding the problem, developing a plan, implementing the plan and checking the result. The purpose of this study is to explore how well Indonesia junior secondary school students apply these four steps in ...

MEASURING IN IMAGES WITH PROJECTIVE GEOMETRY [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 There is a fundamental relationship between projective geometry and the perspective imaging geometry of a pinhole camera. Projective scales have been used to measure within images from the beginnings of photogrammetry, mostly the cross-ratio on a ...

Geometry of Curves with Fractional Derivatives in Lorentz Plane
Journal of New Theory, 2022 In this paper, the geometry of curves is discussed based on the Caputo fractional derivative in the Lorentz plane. Firstly, the tangent vector of a spacelike plane curve is defined in terms of the fractional derivative.

Reaction plane alignment with linearly polarized photon in heavy-ion collisions
Physical Review Research, 2022 The collective observables play critical roles in probing the properties of quark-gluon-plasma created in relativistic heavy-ion collisions, in which the information on initial collision geometry is crucial. However, the initial collision geometry, e.g.,

Focal plane model for flat refractive geometry
Journal of the European Optical Society-Rapid Publications, 2017 Background Flow visualization techniques such as uPIV and droplet imaging determine the measurement volume by the focal plane. Thus, an understanding of how the focal plane moves in reference to the camera is necessary when planar interfaces are present ...
