In this paper, block procedure for some kstep
linear multistep methods, using the Legendre polynomials as the basis
functions, is proposed. Discrete methods were given which were
used in block and implemented for solving the initial value problems, being
continuous interpolant derived and collocated at grid points. Some numerical
examples of ordinary differential equations were solved using the derived
metho ...

In order to solve the
difficulty of the driver’s continuous steering project in the FSEC, the
research on the cruise control system based on the fuzzy PID control is carried
for assisting the driver’s operation. Firstly, the input and output of fuzzy
control is determined, and the fuzzy rule table is established to complete the
design of fuzzy PID control system. Secondly, the fuzzy controller is established
in MATLAB, and the f ...

According to the ideal vehicle model with two
degrees of freedom of the transverse effect of yaw rate and sideslip angle of
the vehicle stability, the yaw rate and side slip angle as the control
parameter of vehicle stability control system, through the PID control
algorithm and the Genetic Optimization PID control algorithm is studied on the
simulation diagram, and
building in matlab/simulink, the
author makes a comparison an ...

Prediction
of a child HIV status poses real challenges in medical research. Even though
there are different statistical techniques and machine learning algorithms that
have been used to predict models like HIV for the clinical data with binary
outcome variables, yet neural network techniques are major participants for
prediction purposes. HIV is the primary cause of mortality among women of
reproductive age globally an ...

This study involved an investigation of factors that
affect a graduate applicant in accepting an offer of admission and enrolling in
a graduate program of study at a midsized public university. A predictive
model was developed, using Decision Tree methodology to assess the probability
that an admitted student would enroll in the program during the semester following
acceptance. The study included actual
application information su ...

The paper considers the theory of the phenomena associated with the Sun’s passage in the sky when the parameters of the orbital and rotational motion of the Earth are changing. The author found that the obliquity changes from 14.8° to 32.1°. These results explain the variations of paleoclimate and are consistent with several testimonies of paleoastronomy. The program SunPhenomn.mcd developed in MathCad to calculate the duration of ...

Dengue is a flavivirus,
transmitted to human through the bites of infected Aedes aegypti and A. albopictus mosquitoes. In this
paper, we analyze a new system of ordinary differential equations which
incorporates saturated in ...

This study first
considered using 5 dimensions/variables of color readings (including blue,
green, saturation, red, hue) to predict the concentration of matter. The
procedure was demonstrated using internet acquired data in the public domain. A
stepwise regression method based on software MATLAB was used to build a model
to predict the concentration of the sulfur dioxide. In the course of the study,
we also discussed other linear ...

In several areas of
engineering, it is
possible to put real problems in mathematical functions; when we represent a problem with variables in the
form of function, we were
able to extract various information from it. This paper compared two different
mathematical methods, being the finite difference method and the Fourth Order
RangeKutta method, to analyze the concentration and temperature of ...

In this paper, we introduce the concept of weakly Ccontraction mapping in modular metric
spaces. And we established some fixed point results in wcomplete spaces. Our results encompass various generalizations of
Banach contraction.
