Abstract: The growing demand on wireless communication service has created the necessity to support higher data rates for multimedia services. .As next generation wireless communication networks are expected to provide broadband multimedia services such as voice, web browsing, video conferencing etc. For high data rate achievement one must enhance the capacity of the wireless communication system. The capacity of a communication system can be enhanced by using OFDM system. OFDM is commonly used for communication system due to its high transmission rate and robustness against multipath fading So as to enhance the capacity of fading channels the OFDM system are combined to form hybrid system. Capacity is the measure of maximum information that can be transmitted reliably over a channel. This paper review on different channel capacity enhancement techniques used in OFDM system is SVD (Singular Value Decomposition), water Filling algorithm.
A Review of Maximum Power Point Tracking: Design and Implementationpaperpublications3
Abstract: Photovoltaic Energy is the most important Energy Resource since it is clean pollution free and inexhaustible. In recent years a large number of techniques have been proposed for tracking the Maximum Power Point. PV array has non-linear I-V characteristic and output power depends on environmental conditions such as solar irradiation and temperature. There is a point on I-V, P-V characteristic curve of PV array called as Maximum Power Point (MPP), where the PV system produces its maximum output power. Location of MPP changes with change in environmental condition. The purpose of MPPT is to adjust the solar operating voltage close to MPP under changing environmental conditions. In order to continuously gather the maximum power from the PV array, they have to operate at their MPPT despite of the inhomogeneous change in environmental conditions. The two most commonly algorithms for PV applications as they are easy to Implement are Beta method Incremental Conductance (Inc. Con.).Beta algorithm is a type of MPPT algorithm. It is having fast tracking ability. The algorithm has been verified on a photovoltaic system, A review of various MPPT algorithms is proposed with more focus on above two algorithms.

Simulation of Locomotive Control of Traction Motor Using a New Bidirectional ...paperpublications3
Abstract: This project mainly concentrates on a simulation of locomotive control of traction motors with a new bidirectional DC-DC-AC converter using Renewable Energy Sources. The existing system is developed with four quadrant operation of dc series motor or induction motor fed voltage and frequency control using power electronic controllers. But in this system the efficiency is low and speed control is not synchronized with other motors. Therefore there is jerking of compartments, uniform braking is not possible in the traction system. The DC motors have been utilized for traction for over one hundred years and were originally chosen because of their inherent compatibility with traction power supplies and ease of mounting within locomotive bogies. The proposed system is designed with fuel cell based bidirectional DC-DC-AC dual inverter for traction motor to optimize third harmonic distortion, switching pattern losses, voltage fluctuations, reducing of switches, cost and also increasing efficiency and feasible operation of traction motors. The Fuel cell based system is powered to the traction motor to run forward, reverse and regenerative braking operation with the help of bidirectional control. So that the kinematic operation of traction motor is control the voltage, speed, torque levels using the ZVS DC-DC-AC converters. The proposed multilevel inverter minimizes the THD with the implementation of Z-source inverter. It is useful in boosting the voltage and additionally reducing the voltage fluctuations in the nine switch Z-source inverter. In a fuel cell powered to traction system the bidirectional dc-dc converter and inverter are essential for efficient performance of the traction motor. The simulation of dual converters is developed using MATLAB/SIMULINK and rotor current, stator current, stator voltage, rotor speed, electromagnetic torque and rotor angle is obtained for the traction motor. The multilevel inverters are developed to reduce the total third harmonic distortions (THD) in the converters. The multilevel converters are used to reduce the switching pattern losses. The performance of the traction system is compatible and running of motors is continuous without any disturbances. The most advantageous of the system is the multistep boost ZVS converter is implemented to maintain the constant power output.
Visible Light Communication and Device Switching Using Embedded Web Serverpaperpublications3
Abstract: A wireless optical networking technology that uses light-emitting diodes (LEDs) for transmission of data can be termed as Li-Fi also known as Visible Light Communication. The main purpose of this paper is particularly to show the advantages of Li-Fi technology in audio transmission and device switching using an embedded web server with light as the medium of transmission. Here the LED is used as the source of light for transmitting the necessary information to the receiver. This technology enables in sending more data to the receiving end very quickly. Li-Fi makes use of transmitter fitted with LED lamps that can illuminate a room as well as transmit information. As this technology uses LEDs, there is no need of separate infrastructure to be deployed exclusively for this purpose. Thus existing LED lights in conjunction with a transmitter circuit can be used for data transmission which can be received by the receiver equipped with appropriate circuitry thereby reducing the use of Radio Frequency for wireless transmission of data.

Implementation of T-Junction Traffic Light Control System Using Simatic S7-20...IJERA Editor
A conventional traffic light control system is designed by using devices such as timers, relays and
contactors etc. The critical timing operation is required to be carried out under the existence of heavy
traffic situations. This conventional practice leads to many problems that need additional maintenance
cost and subsequent delay for a long time. With the help of a PLC, the requirement of fast automation
and effective optimization of traffic light control system can be achieved. Use of PLC helps us to
develop this process not only for traffic signal on the roads, but also on the movement of trains and
the transfer of containers in ports in maritime works. In order to provide a solution to the above
problem, this paper introduces an execution and implementation of T-junction traffic control system
using SEIMENS S7-200 PLC. Programming in PLC is written in ladder logic with the help of STEP7

Design Efficient Wireless Monitoring Platform for Recycling Point SpotsIJMTST Journal
There is a growing demand for low cost, very low power and reduced size monitoring systems with
wireless communications, to be used in different kinds of industrial environments. In several countries waste
separation and recycling is a major issue. Consequently, the number of recycling spots has been steadily
increasing. In order to ensure that recycle bins are properly maintained, several monitoring solutions have
been proposed. These still have several limitations, such as requiring wires for power and/or communications
and not being able to fit in all existing types of bins. This paper presents WECO, a wireless embedded solution
for monitoring the level of the bins located in recycling spots. The proposed system automatically alerts a
remote central station when a bin reaches a programmable filling level, thus avoiding the need to spot check
if the bin is full and ensuring that the recycling spot is kept clean. The developed prototype required
hardware-software co-design and aimed to meet the above mentioned requirements, resorting to the IEEE
802.15.4 protocol for wireless communications between all nodes in the network, each based on a
System-On-Chip CC2530 from Texas Instruments. Due to its wireless nature, the architecture requires a
battery for power supplying the nodes, with a life time of at least six years. The filling level readings of each
bin in a recycling spot are made using an ultrasonic sensor. The data collected by the monitoring platform is
then sent to the remote central station that processes it in order to optimize routes and establish a scheduled
collection of the recycling spots.
Clock gating is an effective method of reducing the dynamic power consumption in synchronous circuits.
One of the ways to achieve this is by masking the clock that goes to the idle portion of the circuit. In This paper
we will present a comparative analysis of existing clock gating techniques on some synchronous digital design
like ALU (Arithmetic logical unit) etc. Also a new clock gating technique that provides more immunity to the
existing problem in available technique. In new proposed clock gating the Gated Clock Generation Circuit is using
tri state buffer and Gated logic is used which is created by the combination of double gated (AND, OR, AND
logic gate) with bubbled input respectively. This circuit saves power even when Target device's clock is ON. All
experiments are done on Xilinx14.1 EDA tool. Mentor Graphics Model SIM. For power calculation we are using
XPOWER. Sparten-3 (90nm) FPGA platform is used for result and analysis. The proposed design will reduce the
hardware complexity with approximately 10-20%. Similar clock power complexity will reduce with 5-10%.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

1. INTRODUCTION
Over the years of demand for high quality and greater efficiency and automated machines has increased in the industrial
sector. In the industrial sector, continuous monitoring, measurement and inspection were required which causes the error
at various stages with human workers and also due to lack of few features of microcontroller. Thus, the PLC system was
evolved from the conventional computers in late 60s and early 70s. These first PLCs were installed primarily in
automotive plants because these plants had to be shut down for up to a month at model changeover time. But the earlier
PLCs were used with other new automation techniques to shorter the changeover time. The PLC helps us to reduce the
changeover time to a matter of few days. Now days, the innovative engineers and technicians have been actively seeking
new applications for PLC in substations and SCADA system. SCADA system helps us to continuous monitoring and
controlling the plant without any human workers help. SCADA also have the ability to perform operations at an
unattended location from an attended station or operating centers and to have a definite indication that the operations have
been successfully carried out can provide significant cost saving in the operation of a system. This is actually what is
achieved through SCADA the system (definition recommended by IEEE). PLCs are very cost competitive with traditional
RTUs and have many benefits in substation automation and their use in substation applications will grow. As the use of
substation automation applications increases and the demand for substations and distribution automation increases, the
utility engineer are seeking ways to implement the applications. Selection of an outside firm is the important task of the
utility Engineer and their selection can determine the success or failure of a project.
2. OBJECTIVE OF THIS PAPER
The main objective of this paper is to elaborate the difference between the two brands of PLCs on the basis of their
features and their use in different applications. This paper can be helpful to find the best PLC used for different
applications in different areas.
A. What is Automation?
Automation is combination of mechanization & intelligence. Making products under the control of computers and
programmable controllers is known as Industrial Automation. Manufacturing assembly lines as well as stand-alone
machine tools (CNC machines) and robotic devices fall into this category. Automation is delegation of human control

functions to technical equipment for increasing productivity, better quality, increasing safety in working conditions
reducing manpower & cost.
B. Role of PLC in Industrial automation:
PLC (Programmable Logic Controller) is basically a solid state device that performs discrete or sequential logic in a
factory environment. It was originally developed to replace the mechanical relays, timers, counters and to reduce the
number of wires complexity in the industrial plants. PLCs are used to execute the complicated control systems very
reliably.
C. Role of SCADA in Industrial automation:
SCADA is a SUPERVISORY CONTROL and DATA ACQUISITION system. It tells us what is happening inside the
plant while sitting inside the control room or thousands of miles away from the plant with the help of internet. SCADA
system operation involves real time data exchange from the field device as well as with other control system like DCS
(Distributed Control System) and PI(Plant Information) system.

Acc. to this, Allen Bradley is best because it has a function block in which all the addresses of the timers, counters, Inputs,
Outputs and Memories etc. are stored. So, no need of learning the addresses is required. Whereas in Siemens function
block is absent, so it is difficult to remind each address of the component used.

Pictorial representation of the difference between the counters of both the PLCs
In Siemens PLC, counter need a reset pulse to reset their input but in A. Bradley’s PLC the counter automatically get
reset. So, extra pulse is not required in it. Basic difference between the A. Bradley and Siemens PLC is the Up down
counter, which is not present in the A. Bradley’s PLC, so we need to add multiple math blocks in it.
a. Up counter:

From counter point of view Siemens is better than the A. Bradley because in Allen Bradley’s PLC the Up-down counter is
not present. So, we need to use two counters in it which makes the ladder busy and the circuit complexity increases.
Pictorial representation of the difference between the remote I/Os hardware configuration of both the PLCs
In the Siemens remote I/O hardware configurations, the separate rack is required for the remote I/Os and their hardware
configuring is not so easy because it require different parameters for this whereas in A. Bradley remote configuring is
easy but it take long time to be configured. In Siemens 4 racks are added whereas in Allen Bradley only one rack with no.
of I/Os are added in it.
I. Siemens remote I/O configuration screen is:
II. Compact Logix remote I/O configuration screen is:
For the remote hardware configuring, Siemens is best because of their universal cards used which gives us universal area
for controlling the PLC.

III. Difference between Allen Bradley and Siemens on the basis of their languages:
Siemens (S7-200) support only 3 languages whereas Allen Bradley (RS logix 500) supports only one language that is
ladder logics.
If we add DCS in Siemens PLC then it support all 6 languages (like CFC, SFC, LD, FBD, IL, ST) whereas in Allen
Bradley RS logix 5000 supports only 4 languages.
So as a result Siemens is best because of the use of DCS (Distributed control system).
DCS is required to adjust the quality of system, controlling of temperature, pressure and water level etc.
IV. Difference between Allen Bradley and Siemens on the basis of their SCADA system:
S.No. Allen Bradley’s SCADA Siemens SCADA
1. RS view 32 Wincc
2. Less features. More features.
3. Less complicated and less costly. More complicated and costly.
4. Not used for visual basic. Used for visual basic.
5. It can be used for many type of PLCs. Generally used for Siemens.
6. Protocol used are DDE OPC,DD. Only MPI OPC server is used.

VI. Difference between Allen Bradley and Siemens on behalf of their applications
We have consider the industrial application like Water treatment plant in which the motor rotation , temperature
controlling and Valve opening is done by the use of remote I/Os and is also shown in the SCADA system.

SCADA representation
RS view 32 Wincc
For this projects point of view Allen Bradley PLC is the best because of the presence of scale block which complete the
program in less no. of rungs due to which less complexity occur in the program and the program become more accurate.
4. RESULT
S.No. Parameter Allen Bradley Siemens
1. Cost Less More due to more no. of features
2. Memory Less than Siemens PLC More than the Allen Bradley
3. Latest HMI’s Features Less More
4. Online modifications Not done Done with the use of DCS
5. Programming tool RS Logix is simpler TIA portal(VIX) is tough than the RS Logix
6. Synchronization Time Pulse
7. Safe connectivity In this we need to hardwire
the same connection.
It includes the safe connectivity of drives
and devices over the network.
8. Software comfort level Less than Siemens More than the Allen Bradley
9. Safety Requires additional cards. Inbuilt
10. No. of safety runtime groups One two
5. CONCLUSION
A review of Allen Bradley v/s Siemens from user point of view is described in this paper. This paper show the
comparison between the different techniques used in it. In this paper several points are taken on the basis of which it is
concluded that Siemens PLC is better than the Allen Bradley in every point either they are costly due to their advance
features in SCADA, PLC, Drives and also in HMI. Now days Allen Bradley is also trying to improve their software
versions but as the time continues may be in future Allen Bradley’s PLC will compete with the Siemens PLC so far.
