Spherical Rectangles [PDF]

open access: yesArnold Mathematical Journal, 2016
We study spherical quadrilaterals whose angles are odd multiples of pi/2, and the equivalent accessory parameter problem for the Heun equation. We obtain a classification of these quadrilaterals up to isometry. For given angles, there are finitely many one-dimensional continuous families which we enumerate.

Rectangle Transformation Problem [PDF]

open access: yesAlgorithmica, 2019
In this paper, we propose the rectangle transformation problem (RTP) and its variants. RTP asks for a transformation by a rectangle partition between two rectangles of the same area. We are interested in the minimum RTP which requires to minimize the partition size. We mainly focus on the strict rectangle transformation problem (SRTP) in which rotation

Research on Jewelry Positioning Technology Based on Minimum Bounding Rectangle [PDF]

open access: yesJisuanji gongcheng, 2016
The length and width of the irregular object is difficult to be unified in an image,and the traditional detection algorithm is not accurate enough.For this problem,this paper states an automatic location detection algorithm.In order to obtain the minimum

Mass Transfer Behaviors and Battery Performance of a Ferrocyanide-Based Organic Redox Flow Battery with Different Electrode Shapes

open access: yesEnergies, 2023
The ferrocyanide-based organic redox flow battery (ferrocyanide-based ORFB), based on electrochemistry, has become a potential energy storage technology due to its low price, eco-friendliness, safety, and convenience. However, its low efficiency and poor

Random Rectangular Graphs [PDF]

open access: yes, 2015
A generalization of the random geometric graph (RGG) model is proposed by considering a set of points uniformly and independently distributed on a rectangle of unit area instead of on a unit square [0,1]^2.

Orthogonal Latin Rectangles [PDF]

open access: yesCombinatorics, Probability and Computing, 2008
We use a greedy probabilistic method to prove that, for every ε > 0, every m × n Latin rectangle on n symbols has an orthogonal mate, where m = (1 − ε)n. That is, we show the existence of a second Latin rectangle such that no pair of the mn cells receives the same pair of symbols in the two rectangles.

A test problem for visual investigation of high-dimensional multi-objective search [PDF]

open access: yes, 2014
An inherent problem in multiobjective optimization is that the visual observation of solution vectors with four or more objectives is infeasible, which brings major difficulties for algorithmic design, examination, and development.

6d Dirac fermion on a rectangle; scrutinizing boundary conditions, mode functions and spectrum [PDF]

open access: yes, 2017
We classify possible boundary conditions of a 6d Dirac fermion $\Psi$ on a rectangle under the requirement that the 4d Lorentz structure is maintained, and derive the profiles and spectrum of the zero modes and nonzero KK modes under the two specific ...
