Studies have shown that number line estimation is important for learning. However, it is yet unclear if number line estimation predicts different mathematical skills in different grades after controlling for age, non-verbal cognitive ability, attention, and working memory. The purpose of this study was to examine the role of number line estimation on two mathematical skills (calculation fluency...

 After the classification of the flag-transitive linear spaces, the attention has been turned to line-transitive linear spaces. In this article, we present a partial classification of the finite linear spaces $mathcal S$ on which an almost simple group $G$ with the socle $G_2(q)$ acts line-transitively.

The simulation analysis numerically investigates the thermoelastic lubricated interfacial Textured Micro-Element (TME) load-bearing contact, a theoretical model is proposed, and effective friction reduction Anti-Thermoelastic Scuffing Load bearing (ATSLB) capacity between random rough Meshing Teeth Surfaces (MTS) are presented, mechanism linking lubrication, TME meshing ATSLB revealed. real con...

Abstract. To simulate transient wind turbine wake interaction problems using limited data, two new variants of the actuator line technique are proposed in which rotor blade forces computed locally generic load data. The models, extensions disk force models by Navarro Diaz et al. (2019a) and Sørensen (2020), only demand thrust power coefficients tip speed ratio as input parameters. In paper anal...

Integration of the PV into the electrical grid needs power electronic interface. This power electronic interface should have some key features and should come up with grid codes. One of the important criteria is the quality and harmonic contents of the current being injected to the grid. High-order harmonics of the grid current should be very limited (lower than 0.3% of the fundamental current)...

T h i s paper dawribcs a new face identification algorithm with two stages. This fitst stage monitors a sequence of face images to select a desired frame for identification and Face identification is performed in the second stage. The face identification algorithm is hased on the geometric parameters of size and distance of the facia[ feature ohjwts (the eyes, the nose. the mouth. etc) The fram...

Python implementation of permutations is presented. Three classes are introduced: Perm for permutations, Group for permutation groups, and PermError to report any errors for both classes. The class Perm is based on Python dictionaries and utilize cycle notation. The methods of calculation for the perm order, parity, ranking and unranking are given. A random permutation generation is also shown....
