IMPROVE STUDENT LEARNING OUTCOMES USING STUDENT WORKSHEETS BASED ON THE APOS MODEL ASSISTED BY GEOGEBRA

open access: yesAksioma: Jurnal Program Studi Pendidikan Matematika, 2023
The observation results showed that practicum activities and student learning outcomes in algebra courses were not optimal. Therefore, a learning model is needed that can make students carry out practical activities directly in class and can improve ...

COMPARISON OF PARTICLE SWARM OPTIMIZATION AND GENETIC ALGORITHM IN RATIONAL FUNCTION MODEL OPTIMIZATION [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Rational Function Models (RFM) are one of the most considerable approaches for spatial information extraction from satellite images especially where there is no access to the sensor parameters. As there is no physical meaning for the terms of RFM, in the

Network model of on-chip antennas [PDF]

open access: yesAdvances in Radio Science, 2011
A Network model of an ultra-wide band, intra-chip wireless link is presented. Numerical data of Z-parameters, obtained from full wave simulation of the structure, are used to obtain a rational function representation via the Vector Fitting procedure ...

S(3) skyrmions and the rational map ansatz [PDF]

open access: yes, 2000
This paper discusses multi-skyrmions on the 3-sphere with variable radius L using the rational map ansatz. For baryon number B = 3,...,9 this ansatz produces the lowest energy solutions known so far.

On Canonical Models for Rational Functions over Infinite Words.

open access: yes, 2018
This paper investigates canonical transducers for rational functions over infinite words, i.e. functions of infinite words defined by finite transducers. We first consider sequential functions, defined by finite transducers with a deterministic underlying automaton.
