Fractal symbolic analysis [PDF]

open access: yesProceedings of the 15th international conference on Supercomputing, 2001
Modern compilers restructure programs to improve their efficiency. Dependence analysis is the most widely used technique for proving the correctness of such transformations, but it suffers from the limitation that it considers only the memory locations read and written by a statement without considering what is being computed by that ...

Symbolic object code analysis [PDF]

open access: yesInternational Journal on Software Tools for Technology Transfer, 2010
Current software model checkers quickly reach their limits when being applied to verifying pointer safety properties in source code that includes function pointers and inlined assembly. This paper introduces an alternative technique for checking pointer safety violations, called Symbolic Object Code Analysis (SOCA), which is based on bounded symbolic ...

Selection of Embedding Dimension and Delay Time in Phase Space Reconstruction via Symbolic Dynamics

open access: yesEntropy, 2021
The modeling and prediction of chaotic time series require proper reconstruction of the state space from the available data in order to successfully estimate invariant properties of the embedded attractor.

Time Series Complexities and Their Relationship to Forecasting Performance

open access: yesEntropy, 2020
Entropy is a key concept in the characterization of uncertainty for any given signal, and its extensions such as Spectral Entropy and Permutation Entropy. They have been used to measure the complexity of time series.

Evaluating Temporal Correlations in Time Series Using Permutation Entropy, Ordinal Probabilities and Machine Learning

open access: yesEntropy, 2021
Time series analysis comprises a wide repertoire of methods for extracting information from data sets. Despite great advances in time series analysis, identifying and quantifying the strength of nonlinear temporal correlations remain a challenge. We have

Spurious Seasonality Detection: A Non-Parametric Test Proposal

open access: yesEconometrics, 2018
This paper offers a general and comprehensive definition of the day-of-the-week effect. Using symbolic dynamics, we develop a unique test based on ordinal patterns in order to detect it.

Lcapy: symbolic linear circuit analysis with Python [PDF]

open access: yesPeerJ Computer Science, 2022
Lcapy is an open-source Python package for solving linear circuits symbolically. It uses a superposition of DC analysis, AC (phasor) analysis, transient (Laplace) analysis, and noise analysis.

Dynamical decoupled design of a two-dof planar differential belt driven robot using multibody system dynamics

open access: yesNihon Kikai Gakkai ronbunshu, 2022
In this paper, a novel dynamical decoupled design of a two-dof differential belt-driven parallel robot is proposed. Equation of motion of the robot, including the inside mechanical properties of pulleys and sliders, are derived by the symbolic multibody ...

Identifying the Most Relevant Lag with Runs

open access: yesEntropy, 2015
In this paper, we propose a nonparametric statistical tool to identify the most relevant lag in the model description of a time series. It is also shown that it can be used for model identification.

Symbolic Pole/Zero Analysis [PDF]

open access: yes, 2012
Capítulo 11.-- El pdf es la versión post-print. Extraction of pole/zero expressions as a function of circuit parameters has traditionally been an essential tool for designers. In this Chapter, the main specific techniques for symbolic pole/zero extraction are described and their pros and cons are discussed.
