For years, LabVIEW has enabled engineers and scientists to develop sophisticated autonomous systems. At its core, Lab VIEW is widely used for sensor and actuator connectivity and currently offers more than 8000 drivers for measurement devices. Furthermore, with new libraries for autonomy and an entirely new suite of robotics-specific sensor and actuator drivers, LabVIEW provides all of the necessary tools for robotics development. The DC Motor is an attractive piece of equipment in many industrial applications requiring variable speed and load characteristics due to its ease of controllability. Speed of a DC motor varies proportional to the input voltage. With a fixed supply voltage the speed of the motor can be changed. This paper focuses on controlling the speed and direction of a Robot using PWM technique (varying duty cycle of a square wave) and Arduino. The four different keys are assigned for the forward, backward, left and right movement and it is controlled by using LabVIEW interface Arduino (LIFA).

Design of smart wireless changeover for continuous electric current feeding f...IJECEIAES
Electric power has become a vital element for life today. Despite this importance, electric power consumers in Iraq suffer from the problem of noncontinuity and daily electric power supply interruption. This problem led to the use of various sources of electric power as an alternative to compensate for the shortage of electric power provided by the Iraqi national grid. In this work, a smart wireless changeover device is designed using wireless sensor networks technology aiming to solve problem caused by the multiplicity of power sources received at home and governmental buildings in Iraq by controlling operation of some electrical devices (which consume high current) in the home or workplace automatically when changing source of electricity from one to another. This solution will help to ensure the continuity of electric current feeding from power sources of variable capacities, also, to rationalize power consumption by assigning an operation priority to electric devices. Furthermore, a statistical measurement as a case study was performed in a building with a total power consumption of 160.8 KW/h. The result showed that the device functions effectively and it is capable of achieving an average saving in power of about 50% to 86% depending on the applied priorities and case study scenario.
IOT based Automatic Colour Sorting Machinevivatechijri
In our day - to - day life we use wide range of products .The manufacturing and production of these
products are done in many small scale and large scale industries. Arranging products manually make quality
consistent issue. Nowadays, After manufacturing and production of the products the main difficulties are faced is
the sorting of products. Arranging of products in an industry is a poor modern process, which is largely done
physically. The machine which is consistent and sort products according to their size, colour, shape and weight
etc. are needed in industry which helps in consuming time and human interactions. This paper gives a brief

Wireless Mobile Charger Design Based on Inductive Couplingijtsrd
This research described the construction and implementation of the contactless wireless mobile phone battery charging which becomes popularity nowadays. The power was transferred to the destination by means of inductive coupling between two coils. In transmitter part, the desired frequency was produced from Arduino by means of PWM Pulse Width Modulation . This frequency was used to drive the induction coil by using MOSFET driver. The MOSFET operated as a switch in terms of T on and T off. The power in transmitter coil was transmitted to surroundings by means of electromagnetic field. The receiver coil was induced by electromagnetic field and produces DC voltage. That converted DC voltage was filtered by capacitor and then regulates to required voltage by using voltage regulator. Optimal frequency range for maximum power transfer is gained by performing theatrical approach and experimental test.

In this project, a failure monitoring system is developed by using the vibration and location information of balises in railway signaling. A lot of field equipment in railway are loosening and broken in time period so that they need maintenance due to the vibrations that occur due to high speed trains traffic and railway vehicles impact.

In this scope, it is aimed to make maintenance works more efficient, have no delayed trains, detect previously failure location and intervene in failure timely, by detecting and controlling balise cases such as loosening, out of place and the data consistency error that happens because of balise physical state. In this project, the communication is provided with I2C, Modbus RTU (Remote Terminal Unit) and RS485 standards by using Arduino Uno cards and MPU6050 IMU (Inertial Measurement Unit) sensors in laboratory. Each used sensors are in slave mode and computer interface designed with C# is in master mode. Fault situations in the system are checked instant by the interface. (it is assumed to mount the IMU sensor and the Arduino circuit on the balise) it is seen that the interface responds to the sensor movements instant and the system works well in the end of test processes.

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.

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.

Deepam Dubey (Sc-B), National Institute of Electronics & Information Technology
An actuator is a component of a machine that is
responsible for moving or controlling a mechanism or
system.
An actuator requires a control signal and a source of
energy.
In Robot we use Electric Actuator.

42. Memories
Deepam Dubey (Sc-B), National Institute of Electronics & Information Technology
A memory is just like a human brain. It is used to store
data and instruction.
Memory is primarily of two types
Internal Memory − cache memory and
primary/main memory
External Memory − magnetic disk / optical disk etc.

A RAM constitutes the internal memory of the CPU for
storing data, program and program result.
It is read/write memory.
RAM is volatile, i.e. data stored in it is lost when we
switch off the computer or if there is a power failure.
RAM (Random Access Memory)

The memory from which we can only read but cannot
write on it.
This type of memory is non-volatile.
A ROM, stores such instruction as are required to start
the system when electricity is first turned on.
