Faster Time to Market using Scilab/XCOS/X2C for motor control algorithm devel...Scilab
Rapid Prototyping becomes very popular for faster algorithm development. With a graphical representation of the algorithm and the possibility to simulate complete designs, engineers can help to reduce the time to market. A tight integration with MPLAB-X IDE allows the combination with standard C-coding to easily get mass production code. This solution was used to optimise a sensorless field oriented controlled PMSM motor driven pump efficiency. A model for closed loop simulation was developed using X2C blocks [1][2] for the FOC algorithm based on the existing application note AN1292 [3]. Enhancements to the original version were implemented and verified with simulation. The X2C Communicator was used to generate code of the new algorithm. With the online debugging capabilities and the scope functionality the algorithm was further tuned and optimized to achieve the highest possible efficiency of the pump.

The document summarizes the implementation of a toolbox for Scilab that converts figures to TikZ/LaTeX format. The toolbox was created to allow including Scilab graphs in scientific papers. It gathers figure attributes from Scilab and generates the necessary TikZ code. The toolbox is currently able to convert basic 2D plots but further improvements are planned to support additional features like subplots and 3D plots.
This document discusses model-based design of mission-critical avionics using Scilab/Xcos. It describes the ARGO project, which aims to help software developers better utilize multiprocessor hardware platforms. As a case study, the document details modeling a Terrain Awareness and Warning System for DLR's A320 simulator using Scilab/Xcos blocks. It discusses modeling the system controller, plant, and performing X-in-the-loop testing of the model. Future work includes integrating the system onto an AURIX multicore board and testing it with pilots in DLR's simulator.
The document discusses polarization imaging and processing polarization data with Scilab. It describes measuring polarization with cameras, developing algorithms in Scilab to process polarization images and extract values like Stokes parameters, and work to transfer the Scilab code into a product as a DLL for integration into industrial inspection systems. The goal is to provide software for online industrial polarization imaging and analysis of properties like stress in glass.
This document discusses ArcelorMittal's use of numerical models for research and development. It introduces the Diabolo paradigm, which is a solution developed using ESI software to address some key issues with managing and sharing models. Specifically, the Diabolo paradigm creates a centralized model repository and toolbox to make models more reusable and easier to share across different users and geographic locations. It aims to support the full lifecycle of models and ease multi-domain simulations. Advanced use cases discussed include building physics simulation, optimization tools, and a statistical model toolbox.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECTjpsjournal1
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.
Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.

Numerical
simulation
is
nowadays
essential
in
system
design
process.
Complex
phenomena
simulation
(physical,
mechanical,
electronics,
etc.)
allows
the
study
of
their
behavior
and
results
without
having
to
conduct
costly
real
experiments.
Widely
used
in
the
world
of
industry,
the
future
generation
of
engineers
and
scientists
are
trained
since
secondary
school
to
the
concepts
of
modeling
and
simulation.
Xcos
is
Scilab
tool
dedicated
to
the
modeling
and
simulation
of
hybrid
dynamic
systems
including
both
continuous
and
discrete
models.
It
also
allows
simulating
systems
governed
by
explicit
equations
(causal
simulation)
and
implicit
equations
(acausal
simulation).
Xcos
includes
a
graphical
editor
which
allows
to
easily
represent
models
as
block
diagrams
by
connecting
the
blocks
to
each
other.
Each
block
represents
a
predefined
basic
function
or
a
user-‐defined
one.
General
environment
After
launching
Scilab,
the
environment
by
default
consists
of
the
console,
files
and
variables
browsers
and
a
command
history.
In
the
console
after
the
prompt
“
-->
”,
just
type
a
command
and
press
the
Enter
key
to
obtain
the
corresponding
result.
Xcos
can
be
launched:
• From
the
toolbar,
via
the
icon,
or
• From
the
menu
bar,
in
Applications / Xcos,
or
• From
the
console,
in
typing:
-->xcos
6. Xcos

Xcos
opens
by
default
with
two
windows:
• A
palette
browser
which
provides
a
set
of
predefined
blocks,
• An
editing
window
which
is
the
working
space
to
design
diagrams.
To
design
a
diagram,
just
select
blocks
in
the
palette
browser
and
position
them
in
the
editing
window
(click,
drag
and
drop).
Blocks
are
then
connected
to
each
other
using
their
different
ports
(input,
output,
event)
in
order
to
simulate
the
created
model.
Example
of
a
simple
diagram
design
We
are
going
to
explain
how
to
design
from
scratch
a
model
of
continuous-‐time
system
represented
by
a
first-‐order
transfer
function.
Launch
Xcos.
As
seen
before,
Xcos
opens
by
default
with
the
palette
browser
and
an
editing
window.
In
the
palette
browser,
we
are
going
to
use
the
following
blocks:
Designation

Arrange
the
blocks
in
the
editing
window.
To
connect
the
input
and
output
ports
to
each
other,
click
on
the
output
(black
arrow)
of
the
STEP-‐FUNCTION
block
and
in
maintaining
the
mouse
button
pressed,
connect
it
to
the
input
port
of
the
CLR
block
(a
green
highlighted
square
appears
to
indicate
that
the
link
is
correct)
as
described
in
the
images
below:
Release
to
complete
the
link.
Complete
the
connections
between
the
different
blocks
to
achieve
this
result:
It
is
possible
to
improve
the
general
look
of
your
diagram
in
using
the
blocks
alignment
options
(Format
Menu/Align
blocks)
and
the
links
style
(Format
Menu/Link
style).
At
any
time,
blocks
can
be
moved
or
repositioned
by
selecting
them
and
by
maintaining
the
mouse
button
pressed
while
moving
them.
Release
the
blocks
in
the
desired
position.
Simulation
is
launched
by
clicking
on
the
icon
(or
from
the
Simulation
Menu/Start)
and
can
be
stopped
by
clicking
on
the
icon
(or
from
the
Simulation
Menu/Stop).
A
new
window
is
displayed
(scope)
with
the
simulation
running.
At
the
bottom
of
the
diagram
editing
window,
a
statement
indicates
that
the
simulation
is
in
progress:
8. Xcos

You
can
see
that
the
simulation
time
is
quite
long
(you
may
have
needed
to
stop
the
simulation
while
running)
and
that
the
response
is
flat.
Thus,
we
choose
to
modify
the
parameters
of
CLR
block
and
of
the
simulation.
A
"Context"
containing
Scilab
script
allows
easy
use
of
functions
and
variables
in
Xcos
blocks.
We
are
going
to
use
this
context
to
set
the
blocks
parameters
for
diagram
simulation.
Click
on
Simulation/Set
Context
in
the
menu
bar
and
define
the
following
variables:
• K
=
1
• Tau
=
1
You
can
now
use
these
variables
to
set
up
the
diagram
blocks.
Double-‐click
on
CLR
block.
A
dialog
box
opens
with
the
default
settings
of
the
block.
Modify
these
settings
as
follows:
• Numerator:
K
• Denominator:
1+Tau*s
The
new
transfer
function
is
displayed
on
the
block:
If
necessary,
enlarge
the
block
so
that
the
display
fits
in
it.
9. Xcos

We
are
now
going
to
set
up
the
simulation
and
the
blocks
to
visualize
the
time
response
of
the
system
to
a
stepe.
For
this,
we
limit
the
simulation
time
to
5
seconds
(Simulation
Menu/Setup)
in
modifying
the
final
integration
time.
Double-‐click
on
CSCOPE
block
to
set
up
the
display
of
values
between
0
and
1.2,
then
the
scope
refresh
period
to
5
seconds.
To
do
it,
change
the
following
settings:
• Ymin:
0
• Ymax:
1.2
• Refresh
period:
5
Restart
the
simulation
and
view
the
result:
Superblocks
To
ease
the
understanding
of
certain
diagrams,
it
is
often
useful
to
use
superblocks
or
composite
blocks.
A
superblock
contains
a
part
of
a
diagram
and
blocks
representing
its
inputs
and
outputs.
The
superblock
can
be
handled
as
a
single
block
within
the
parent
diagram.
After
designing
a
diagram
and
selecting
the
part
of
the
diagram
(or
sub-‐diagram)
that
we
want
to
gather
into
a
block,
the
creation
of
the
superblock
is
done
from
the
menu
Edit/Region
to
superblock.
The
selection
is
now
a
block
which
content
can
be
displayed
by
double-‐click.
A
new
editing
window
opens
with
the
initial
selected
blocks.
10. Xcos

It
is
also
possible
to
hide
the
created
superblock
to
disable
access
to
the
subdiagram.
To
do
so,
right-‐click
on
the
superblock,
then
on
Superblock
Mask/Create.
We
can
also
make
some
sub-‐diagram
configuration
settings
available
in
a
single
setup
interface
by
a
right-‐click
on
the
superblock,
then
Superblock
Mask/Customize.
Then
just
add
the
parameters
you
want
to
make
available.
This
presentation
was
intentionally
short
and
many
other
possibilities
for
simulating
systems
exist
with
many
available
blocks.
To
continue
to
handle

Xcos,
we
invite
you

Install
a
C
compiler
For
some
systems
simulation
(acausal
systems
containing
for
example
hydraulic
or
electrical
blocks),
it
is
necessary
to
have
a
C
compiler
installed
in
the
machine.
Under
Windows
Install
MinGW
module
from
Scilab,
Applications
Menu
/
Module
manager
–
ATOMS
/
Windows
Tools
category.
MinGW
module
will
make
the
link
between
Scilab
and
GCC
compiler
(which
you
15. Xcos
for
very
beginners
-‐
15/15
also
have
to
install
separately).
Follow
the
procedure
detailed
in
the
module
install
window
which
will
guide
you
step
by
step
in
the
install
of
MinGW
and
GCC
compiler.
Under
Linux
GCC
compiler
is
available
by
default
under
Linux
OS.
Just
check
that
the
compiler
is
installed
and
up
to
date
(via
Synaptic,
Yum
or
any
other
package
management
system).
Under
Mac
Download
Xcode
via
the
App
Store
(Mac
OS
≥
10.7)
or
via
the
CD
supplied
with
the
computer
(Mac
OS
10.5
and
10.6).
For
earlier
versions,
see
the
Apple
website.
Confirm
the
possibility
to
use
the
compiler
out
of
Xcode
environment.
To
do
so,
after
launching
Xcode,
go
to
"Settings",
then
"Downloads"
and
in
the
"Components"
tab,
select
the
"Check
for
and
install
updates
automatically"
box
and
install
the
"Command
Line
Tools"
extension.
Naturally,
if
you
already
have
an
installed
C
compiler
in
your
machine,
you
do
not
have
to
install
another
one.
To
check
that
Scilab
has
detected
a
compiler,
use
the
command
that
returns
%T
if
a
compiler
is
installed:
--> haveacompiler()
