In this paper, the
performance of inverted pendulum have been Investigated using
robust control theory. The robust controllers used in this paper
are H∞

Loop Shaping Controllers for a control target deviation of an
angle from vertical of the inverted pendulum using two input
signals (step and impulse). The simulation result shows that the
inverted pendulum with mixed H∞

and percentage overshoot in the step response and having a good
response in the impulse response too. Finally the inverted
pendulum with mixed H∞
Loop Shaping Controller shows the best performance in the
overall simulation result.

Abstract:
Recently, active
suspension system will become important to the vehicle
industries because of its advantages in improving road managing
and ride comfort. This paper offers the development of
mathematical modelling and design of a neural network control
approach. The paper will begin with a mathematical model
designing primarily based at the parameters of the active
suspension system. A nonlinear three by four-way valve-piston
hydraulic actuator became advanced which will make the
suspension system under the active condition. Then, the model
can be analyzed thru MATLAB/Simulink software program. Finally,
the NARMA-L2, model reference and predictive controllers are
designed for the active suspension system. The results are
acquired after designing the simulation of the quarter-car
nonlinear active suspension system. From the simulation end
result using MATLAB/Simulink, the response of the system might
be as compared between the nonlinear active suspension system
with NARMA-L2, model reference and predictive controllers.
Besides that, the evaluation has been made between the proposed
controllers thru the characteristics of the manage objectives
suspension deflection, body acceleration and body travel of the
active suspension system. As a conclusion, designing a nonlinear
active suspension system with a nonlinear hydraulic actuator for
quarter car model has improved the car performance by using a
NARMA-L2 controller. The improvements in performance will
improve road handling and ride comfort performance of the active
suspension system.

Abstract:
This paper affords
the design and improvement of a semi-active suspension system
for an automobile. The main idea is to increase the semi-active
suspension system damping vibration of the automobile body even
as crossing the bump and sine pavement on the road. This system
is modelled for 1 / 4 car system after which the entire system
has been simulated using Mat lab/Simulink. It is used to
physically simulate the quarter vehicle system of the automobile
and have a look at the time domain response to the road
disturbances. H infinity controllers is used to govern the
damping properties of the semi-active suspension system
mechanically. The system is designed in contrast to the most of
the available suspension systems using a third order hydraulic
actuator. The proposed system is compared with H2 optimal
controller to test the performance of the system for the control
targets suspension deflection, body acceleration and body travel
for the bump and sine road disturbances. The simulation result
of this studies reveal the efficiency of the advanced H∞
controller for the quarter car semi-active suspension system.

Abstract:
This paper offers
with the theoretical and computational evaluation of optimal &
robust control problems, with the goal of providing answers to
them with MATLAB simulation. For the robust control, -synthesis
controller and for the optimal control, LQR controller are
designed for a quarter car active suspension system to maximize
the ride comfort and road handling criteria’s of the vehicle.
The proposed controllers are designed using Matlab script
program using time domain analysis for the four road
disturbances (bump, random sine pavement and white noise) for
the control targets suspension deflection, body acceleration and
body travel. Finally the simulation result prove the
effectiveness of the active suspension system with Mu-synthesis
controller.

Abstract:
Coronavirus
disease 2019 (COVID-19) is an
infectious disease
caused by
severe acute respiratory
syndrome coronavirus 2
(SARS-CoV-2).
The virus is
mainly spread
during close
contact and via
respiratory droplets
that are
produced when a person talks, coughs, or sneezes. Respiratory
droplets may be produced during breathing, however, current
research indicates that the virus is not considered
airborne.
People may also contract COVID-19 by touching a contaminated
surface (Fomite) and then
inadvertently transfer the pathogen
to a
mucous membrane
(such as the
eyes, nose, or mouth). It is most contagious when people are
symptomatic, although spread may be possible before symptoms
appear. The virus can live on surfaces up to 72 hours. Time from
exposure to onset of symptoms is generally between two and
fourteen days, with an average of five days. The standard method
of diagnosis
is by
reverse transcription polymerase
chain reaction
(rRT-PCR) from a
nasopharyngeal swab.
The infection can also be diagnosed from a combination of
symptoms, risk factors
and a chest
CT scan
showing features
of pneumonia. This article introduces recent research
reports as references in the related studies.

On the Fundamental Theorem in

Abstract:
Using Jiang function we prove
the fundamental theorem in arithmetic progression of primes
[1-3]. The primes contain only  long
arithmetic progressions, but the primes have no  long
arithmetic progressions. Szemeredi theorem and Green-Tao theorem
are absolutely false. They do not understand the arithmetic
progression of primes [4-15] which is the greatest mathematical
scandals of the world.
