1. Neural networks are being used in manufacturing to optimize steel production processes and control systems. Historical plant operations data that would otherwise sit unused can be utilized by neural networks as online knowledge for artificial intelligence-based process control.
2. Specifically, a steel plant in Western India developed two neural network models to optimize the feed mix ratio for sponge iron production. The models predict raw material quantities, production consumables needed, and sponge iron output based on over 40 input parameters like material costs and qualities.
3. The neural network models were able to accurately match historical plant data, enabling improved process control, economic analysis, and "what-if" scenario planning to optimize production costs and output.
Automated PCB identification and defect-detection system (APIDS)IJECEIAES
Ever growing PCB industry requires automation during manufacturing process to produce defect free products. Machine Vision is widely used as popular means of inspection to find defects in PCBs. However, it is still largely dependent on user input to select algorithm set for the PCB under inspection prior to the beginning of the process. Continuous increase in computation power of computers and image quality of image acquisition devices demands new methods for further automation. This paper proposes a new method to achieve further automation by identifying the type of PCB under inspection prior to begin defect inspection process. Identification of PCB is achieved by using local feature detectors SURF and ORB and using the orientation data acquired to transform the PCB image to the reference image for inspection of defects. A close-loop system is produced as a prototype to reflect the practicality of the idea. A Graphical User Interface was developed using MATLAB to present the proposed system. Test data contained 29 PCBs. Each PCB was tested 5 times for camera acquired images and 3 times for database images. The identification accuracy is 98.66% for database images and 100% for images acquired from the camera. The time taken to detect the model of PCB is recorded and is significantly lower for ORB based identification than SURF based. The system is also a close loop system which detects defects in PCB units. The detection of defects has highest accuracy of 92.3% for best controlled environment scenario. With controlled environment, the system could detect defects in PCB pertaining to smallest of components such as SMDs.
Mobile advertising has grown significantly from 1998 to 2008. During this period, mobile phones evolved from basic calling devices with limited memory and speed to powerful smartphones with large storage, fast processors, and internet access. As mobile internet usage increased worldwide, surpassing fixed internet by 2010, the mobile advertising market also expanded rapidly. Mobile ads can now be highly targeted based on factors like location, demographic information, and user behavior to deliver more relevant messages. However, mobile advertising is still developing and building partnerships and customized content will be important for its continued growth.

This document is an introduction to NoSQL databases presented by Trisha Gee from MongoDB. It discusses relational databases and their advantages like ACID transactions. However, relational databases have disadvantages for large or unstructured datasets. NoSQL databases are non-relational and come in different flavors like key-value stores, document databases, graph databases, and column-oriented databases. NoSQL databases offer more flexibility in schemas and can be a better fit than relational databases depending on an application's needs around queries, scalability, or data structure.

multivariable, non-linear and random
processes. Flere, advanced control
techniques need to be used. Very
often, the challenge of controlling
difficult loops is more a matter of
uncertain data rather than uncertain
process behaviour. In such situations,
artifi cial intelligence techniques using
neural networks help to infer the
current value of process variables from
a collection of related variables such
as the historical data of the process.
Neural net'work technology has been
successfully used in a variety of
process control and optimisation
applications for the last few years.
Artificial neural nerworks, or neural
networks for short are inspired by
biological neural networks found in the
brain of mammals. The mathematical
formulation of neural networks
enables them to "learn" and "organise"
themselves, i.e. adjust various
computational parameters so that the
characteristics of the data are captured
within the neural network formulation.
Neural networks thus can adapt to
changes in data and learn to generalise
the characteristics of input data. For
example, a neural nemrork can learn
the mapping between an input and
output set of data, such that it predicts
the appropriate ouq>ut when presented
with a new input data. This property
can be effectively used in a variety of

Puttlng plant hlstort to usc
In several plants or production
processes, there are a large number of
variables that affect
the production
(output) or product
quality.Therefore, it
is generally diffrcult
to choose the right
combination of all
these variables to
ensure optimality -
that is, maximum
production or best
product quality.
Sometimes, the
effects of the
numerous varia-
bles on optimised
operations are not
fully understood.
Usually a large
arnount of historical
data pertaining to
the operation of the
plant and the values
of the numerous
variables that were
used in the past is
available in plant
logbooks or in the Distributed Control
System. Such historical data can be
readily classified as "near-optimal
operation", "good oPeration" and
"bad operation". Neural networks can
be applied on such historical data to
"learn" the pattern of the variables that
provide the above categories of
operation. Once the network has learnt
these patterns, it is possible to use it in
a predictive mode to identify which
combination ofvariables to use in order
to achieve a desired production or
product quality. A case study of how a
neural network based application was
developed for a steel manufacturer is
discussed in the next section.

The problem of feed mix optimisation
in a steel plant is one of choosing the
"optimal" feed mix ratio of different
iron ores for sponge iron production.
This choice of optimal feed mix ratio
is made by taking into consideration
the following factors: inventory of raw
materials, cost of raw materials, cost
of production consumables.
The first thing to do in developing a
neural network based solution is to
identify all the factors i.e, input
parameters that affect the desired
output values. For example, in the case
of steel production at a major plant site
in western India, the following outPuts
were to be predicted by the neural
network based system using Gensym's
G2 and NeurOn-Line software :
I Quantities of input iron ores
I Quantities of production
consumables needed to Process the
above quantities of iron ore
I Quantity of sponge iron product
that can be produced with the feed mix.
After several discussions with plant
personnel, the input Parameters that
were identified as affecting the outputs
were the cost of various iron ores)
their inventory qualiry parameters of
iron ores and the desired quality of
sponge iron product.
A carefirl analysis ofthe inputs and
outputs identified above revealed that
there are over fotty inputs that affect
the desired output values. This is
because there are five different tyPes
of iron ores. For each of these iron
ores there are six different quality
parameters that need to be taken into
account, thus amounting to thirty
inputs. The rawmaterial cost (5), raw
material inventory (5) and product
quality parameters (3) work out to
another thirteen inputs. There are
nine output values that are to be
predicted by the neural network
model - five raw material quantities,
three production consurnable values
and one sponge iron product quantity.
Instead ofdevelopitg
"

network that takes into account 43
inputs and 9 outputs, the problem was
decomposed into two sub-problems,
each ofwhich had a lesser number of
inputs and outputs as shown
rn Figure I.

Once the above design was
complete and approved by the plant
personnel, then historical data for the
above inputs and outputs were
collected from the plant DCS and log
books and manually filtered. By
filtering, we mean removing input
and output data sets for those daYs

to known instrumentation errors) etc.
Only "good data" after manual
filtering from the previous six months
of operation was collected. This data
was then used for "training" -
adjusting the parameters - of the rwo
neural networks. While the details of
the training algorithm are out of the
scope of such an introductory article,
it must be noted that the algorithm
itself is fairly easy to undersrand and
easily implementable.

Non-Linear Models: The neu-
ral network models built during this
application have captured the operat-
ing practices of the steel plant. Given
a set of raw material inventory qual-
ity, costs and desired product quality
parameters, the two neural network
models can predict the raw material
quantities required to be used and the
arnount of production output and pro-
duction consumables required. The
production personnel can figure out

how much quantiry of raw materials
is to be used for achieving a desired
production target. Further, the pro-
duction supervisors have an estimate

pact on production and

The XOR Logic Gate is implemented in
the form of a neural network. Here, neurons
A and B are the inPut neurons. Neurons la-

of neurons. The output layer of the network

threshold function is less than 0.5, the out-
put is unity; else, if the input is greater than
0.5, the output is zero.
lrt us assurne that the input pattern Pre-
sented to this network is A = I, B : 0.
Then the internal state of the neuron 'HI' is
computed as follows:
(-l) (l) + (r) (0): -r
Since -I< 0.5 (the threshold limit of the
hidden neuron HI), the outPut of neuron
Hl is zero. The internal state of the hidden
neuron H2 is computed as:
(-I) (I) + (r) (0) : -I.
Since -I< - 0.5 ( the threshold of H2), the
output of neuron H2 is zmo.
Now with both HI and H2 outPuts at zrro)
the internal state of neuron 'O' is given as:
(0.5) (0) + (0.5) (0) : o
Since 0 < 0.5 ( the threshold limit of the
inverse threshold function), the output from
neuron 'O' is unity, exacdy what is expected
from an XOR gate. It must be noted that the
XOR gate cannot be implemented in the
form of a neural network if the hidden lay< r
is not present. In other words, the hidden
layer is a necessary part of the network ar-
chitecture if non-linear functions are to be
mapped.
This example illustrates how neural net-
works store knowledge in the form of
weights of their connections. For compli-
cated patterns, there would be a larger
number of neurons used - both in terms of
the number of layers of neurons and also
the number of neurons in each layer. Thus,
only the form of the network changes de-
pending on the problem in hand.
The ptor tnd cons
The technology of neural networks
is still at an early stage of application'
considering that it was only in 1987
that the first commercial aPPlications
of neural networks were rePorted.
Despite this there has been a raPid and
widispread exploitation of the
technology for solving a variety of
problems. The reasons for this
acceptance over multiple domains are
because of the wonderfial benefits that
the technology ofFers. The benefits of
a technology can be better understood
with respect to a specific application
as is apparent from the above case'
When used as a soft sensor or virnral
sensor some of the advantages are:
I The ability to Predict current
or future values using models.
r Avoid laboratory test delaYs if
used as a virfttal sensor and thereby
enhance Process control.
I Identify key influencing
variables: M*y times the sensitivity
of an output to an inPut variable
changes dramatically depending on the
operating region. An off-line model
can predict the sensitivity at the
current operating conditions and not
just an average sensitivity over all
operating points.
I Provide a non-linear model for
Process control.
I Sensor validation: A unit may
already have an on-line sensor, but the
sensor may be subject to frequent er-
rors (bias, drift, dead sensor) and need
frequent maintenance.
A virtual sensor or inferential
sensor can cross-check and validate
the on-line analyser, Providing a
means of detecting when a sensor
becomes f"olty.
Its internal state is given as the weighted
sum of inputs from the previous layer and its

inpot-output data, the neu'ral network
"learns" the patterns by adjusting the weights
of each neuron. Connections (i.e. weights,
w,) between neurons which lead to the "right
answer" are strengthened (i.e. increased in
magnitude) while those leading to "incor-
rect answers" are decreased by repeated ex-
posure to sample problems (i.e. the data

to learn in a manner closely parallel to hu-

there is hardly any physical
maintenance associated with respect
to the sensor itself.
Similar advantages can be identified
for almost any other application of
neural network technology However,
neural networks have their share of
disadvantages.
Neural network technology depends
heavily on the availability of "large,,
amounts of "good" data for training
the network. By "good" data, we
mean data that is representative of the
entire sample space under
consideration. If data covering some
region of interest were not available,
then the network would not be able
to identify panerns belonging to that
reglon.
Put simply, neural nerworks are fairly
good if used to "interpolate" values
within the range of training set data.
Ffowever, their results outside the
training range are complete ly
unknown. Further, there should be
sufficiendy large number of exemplar
data to determine a solution set of
60
weights for the network. Otherwise,
an under-trained network may not
be able to "generalise" information
from the data presented to it.

As has been pointed out earlier, a
neural network application can be de-
veloped only if there is a "large',
amount of "good" data that is repre-
sentative of the domain being mod-
elled. If historical data is unavailable
or if the data does not reflect the cur-
rent operational state of a plant, then
such data will be useless as far as neu-
ral network modelling is concerned.
Choice of software tools
Several vendors have been making
the neural network technology avail-
able for general use. Pavilion Technolo-
gies Inc., USA, has been touting sev-
eral success stories about neural net-
work applications in the process indus-
try using their software package called
Process Insight. Similarly, Gensym
Corporation has a product called
NeurOn-Line which has been put to
use in a wide varietv of industries.
Also, some Distribut"d Cont ol Sys-
tem vendors are making these tech-
nologies available direcdyon the DCS.
For example, Fisher-Rosemount has
a tool called Intelligenr Sensor Toolkit
that enables users to develop inferen-
tial sensing applications directly on
the DCS itself.
Using these software packages, the
details of the network learning proc-
ess and associated weight pattern in
which the knowledge resides are in-
visible, and in reality, unnecessary for
the user to know for using the sys-
tem effectivelv.
It is extremely important to take an
informed decision about the specific
software tool to be used for a particu-
lar project. For example, using
Gensym's NeurOn-Line product, it is
possible to implement an application
that can communicate with the con-
trol system in real-time.
On the other hand, if you have an
existing DCS for which such a soft-
ware tool is just an add-on feature, then
it is better to implement the applica-
tion using such tools. The cost of the

Thus neural networks are tools for non-

Once a non-linear model of a process
is obtained, then the model may be used
to predict the behaviour of the process in
Iuture.
A large number of applications of
neural networks have been reported in
non-linear modelling. Some examples
include: Reactor Models, Autoclave
Models, Furnace Models, Dispersion
Models, Distillation Column Models,
Fluidised Catalytic Cracking lJnit,

Aduanccd control
Non-linear models, as described in the
previous sub-section, can form the basis
for model based control of highlv non-
linear processes, which generallv cannot
be tackled by classical model based
control techniques. A classic example of
a non-linear process is the neutralisation
software tool, the mode of use of the
application (whether on-line or off-
line), flexibility of application develop-
ment, the user interface ar-ailable are
all factors fhat one should s-eigh c.are-
firlly before taking a decision on the
software tool.
Skilled Personnel
As mentioned above, the availabilio'
of sofrware tools has obviated the ne-
cessity of having specialists u.ho
have a deep understanding of the
technology.
Nevertheless, it is important that the
application developer has a general un-
derstanding of the technology so that
he can recognise commonly known
problems during training of the
network.
For example, there are several issues
with respect to neural nerwork design
- choice of the number of hidden lay-
ers, the number of nodes in each hid-
den layer, the learning parameter, the
use of an appropriate learning algo-
rithm, recognising when a network has
begun "memorising" input-output
sets of data.

use of the technology it is found that
the neural network performance has de-
teriorated, itgenerally points to the fact
that the network needs re-training us-
ing a new set of data.
Implementation and payback
The first neural network application
being developed in an organisation can
take as much as 3-4 months before a
working protot)?e is ready For on-line
applications, the development time may
be a litde longer depending on the types
of interfaces with control systems that

been reported in the

are desired. The pay back time for some
of these applications - such as the vir-
tual sensors application - can be easily
computed based on reduced mainte-
nance, faster response time, better prod-
uct qualiry etc. Flowever, in other ap-
plications, such as the case study de-
scribed earlier in this article, where the
network models are used as decision-
support systems, the pavback time may
be more difficult to gaLrge or compute.
Conclusion
The neural network technology has
been around long enough but the pri-
mary impediment to their widespread
use has been the steep learning crrrye
associated with developing applications
by using this. However, with several
vendors making this technology avail-
able for use in an extremelyuser-friendly
manner) applylng it has become as sim-
ple as using a spreadsheet on a PC. The
ability of these networks to learn and
adapt, self-organise and approxirnate
frrnction mappings makes them attrac-
tive for solving fairly complex problems
of automating production.
