Abstract:
This paper offers a short survey
of linear systems Proportional-Integral-Observer design. This
observer has the capacity to estimate simultaneously the states
and unknown inputs which include disturbances or model
uncertainties appearing on the system. The design of state and
output estimation using PO and state, output and disturbance
estimation using PIO is done using Matlab/Simulink successfully.
The simulation is done for estimating using PO and PIO and the
results proved that estimates the state variables and output
correctly when there is no disturbance in the plant and there is
a constant steady-state error in estimation after leading a
constant disturbance into the plant for both state variables and
plant output for the Proportional Observer and there is ability
to estimate state variables, disturbance and system output
correctly with or without the disturbance in plant for the
Proportional Integral Observer.

Abstract:
According to
Freedman equations, the geometry of the universe has three
possibilities namely open, closed and flat. Closed universe
obeys the properties of spherical geometry, open universe has
the properties of hyperbolic geometry and flat universe agrees
with the concepts of classical Euclidean geometry. Recent
measurements of WMAP and Planck predict that to a margin of
0.02% error, our universe is flat. But there is no mathematical
formulation for the shape of our universe. In this work, the
author attempts to show seven mathematical methods for the fate
of our universe. The author’s findings are just some attempts.
The author does not seek any TOP claims. But the author
sincerely believes that these studies may be a small clue for
further probes and research.

Abstract:
The results of present study showed that milk production was
decreases from day 1 to day 40 and slightly increases form day
40 to day 50. This study was conducted from July to September
2020 so heat stress was the major concern that effect the
production because heat stress may lead to reduced to DMI,
increase respiration rate and panting to maintain the body
temperature which ultimately effect the milk production in
lactating cows and buffalos. Apart from heat stress other
reasons for decreasing in milk productions are fluctuations in
daily feeding and mastitis.

Abstract:
South Asian Monsoon Time Scale is proposed and designed by me to
study the South Asian monsoon. This is very useful to study the
South Asian monsoon. So scientists can make this South Asian
Monsoon Time Scale and make further research & develop, promote
& propagate it. Find out it by searching it’s name South Asian
Monsoon Time Scale in all websites or can get by sending your
email to
scientistgangadhar@yahoo.com
I call on world scientists to invent this scale and break down
the mysteries of the aforesaid monsoon. Scientists who want to
invent this scale have trouble in making it, kindly contact me
via my personal email id
gangadhar19582058@gmail.com
and take my assistance in making it. I will help you in making
this scale. A sample scale will also be made and send to you.
For this, a certain amount should be sent for expenses. For
this, they must send the list of events of climate just like
dust storms, monsoon low pressure systems etc. last 140 years
since 1880 formed over the South Asian monsoon region in the
procedure cited below reference. In addition to this, a certain
amount should be sent for expenses. You need to design the
computer model later.

Abstract:
Vehicle windshield wiper system
increases the driving safety by contributing a clear shot
viewing to the driver. In this paper, modelling, designing and
simulation of a vehicle windshield wiper system with robust
control theory is done successfully. H loop shaping
and robust pole placement controllers are used to improve the
wiping speed by tracking a reference speed signals. The
reference speed signals used in this paper are step and sine
wave signals. Comparison of the H loop shaping
and robust pole placement controllers based on the two reference
signals is done and convincing results have been obtained.
Finally the comparative results prove the effectiveness of the
proposed H Loop Shaping
controller to improve the wiping mechanism for the given two
reference signals.

Abstract:
In this paper, a vertically
moving base inverted pendulum control analysis has been done
using Matlab/Simulink Toolbox. Because the vertically moving
base inverted pendulum system is nonlinear and highly unstable,
a feedback control system is used to make the system controlled
and stable. A PI and PID controllers are used to improve the
stability of the pendulum. Comparison of the vertically moving
base inverted pendulum using PI and PID controllers for tracking
a desired angular position of the system using a step and random
input signals and a promising results have been obtained
succesfully.

Deteriorating Items And Linear Demand With Procurement And
Repair

Abstract:
The models with seasonal demand are prevalent because of its
extensive application in the inventory management of the
products with short life cycles. As a type of demand, seasonal
demand is extremely common but is difficult to manage,
efficiently.
Here, we analyze
this inventory system under different situations. We have showed
that our method helps the manufacturer reduce the loss caused by
production disruptions. In this study, the proposed model
considers the deterioration rate as constant. In real life, we
may consider the deterioration rate as a function of time,
stock, and so on.

Abstract:
There are many methods to
deliver the transcription factors into target cells to generate
iPSCs. The first method is retrovirus or lentivirus
transduction. The problem of this technique is the genome
integration of virus DNA which could possibly alter
differentiation potential or other malignant transformation. The
second method is adenoviral vectors to induce iPSC. The
advantage of adenovirus vector based expression is that the
transgenes will not integrate into the house genome, thus
reduces the risk of tumorogenesis. The third one is a plasmid
based transfection that can avoid the genome integration also.
Recently, the Cre-recombinase excisable systems are used in iPSC
induction and subsequent transgene removal making the iPSC
technology closer to clinic applications.
