IR BASED HOME AUTOMATION USING ARDUINO UNOMln Phaneendra
In this work, a remote controlled device is used to control 1 - 6 different single phase loads like Fans, Tube Lights and etc.,
This Automation can be operated up to a 30 feet of distance . Our work is based on Infra-Red(IR) technology and a simple Arduino Board(AB) using Printed Circuit Board(PCB).
The new designed circuit is more advantageous as it is portable, easy to carry and use.
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature. Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines. An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators. Large 50 or 60 Hz three phase alternators in power plants generate most of the world's electric power, which is distributed by electric power grids.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
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. PROJECT #6: ELECTROMAGNETIC CRANE
Teacher’s Notes
The Project
Time Frame: 2-3 weeks
Materials:
• Bolt (1”-2” Long)
• 22-24 Gauge Magnet wire (regular solid core copper wire will work)
Available at Electrosonic, see suppliers
$10 for approx. 200’
• 20+ paperclips
• 2 bowls
• 4.5V – 6V battery
• Construction materials for the physical crane set-up
Description:
This is a difficult project. This project would be appropriate at the grade 11 or 12 level.
The students are required to interface a stepping motor, a DC motor (using an H-Bridge),
an LED and an electromagnet.
has an excellent picture on how to set-up the H-bridge motor.
The goal is to move paperclips from one bowl to another bowl through a 90° rotation.
The crane starts with the magnet up& above the first bowl.
When the program starts:
• LED at the top of the crane starts to flash (crane is moving, Watch out!)
• The crane drops the magnet into the bowl.
• The magnet turns on & collects the paperclips.
• The crane lifts the magnet and paperclips.
• The crane moves through the 90° rotation.
• The crane lowers the magnet and clips into the second bowl
• The magnet shuts off, releasing the paperclips
• The crane lifts the magnet back up
• The crane rotates back to the first bowl
• The LED turns off when the crane stops moving.
Warning!!!
This should not be the first interfacing activity.
This project is too difficult to try without attempting some of the previous activities.
2. Suggested Usage of Pins
The following is a suggesting representation of which pins to use for each control.
Lights Output / Pin # Decimal Value
Electromagnet D0 / Pin 2 1
Flashing Light D1 / Pin 3 2
DC – Motor Control 1 D2 / Pin 4 4
DC – Motor Control 2 D3 / Pin 5 8
Stepper Motor Control 1 D4 / Pin 6 16
Stepper Motor Control 2 D5 / Pin 7 32
Stepper Motor Control 3 D6 / Pin 8 64
Stepper Motor Control 4 D7 / Pin 9 128
H-Bridge (Bi-directional DC motor control)
• To turn the DC motor in one direction, set D2 high & D3 low.
• To turn the DC motor in the opposite direction, set D2 low & D3 high.
• To stop the motor, set both D2 & D3 low.
• DO NOT set both D2 & D3 high!
Stepper control
• Stepper motors work by sending a repeating pattern of bits to the different coils.
• Taping a popsicle stick to the end of the stepper motor and using a protractor is a good way to
measure the angle per step.
For our example, the stepper motor is controlled by D4-D7. The following block of code will make
the stepper motor turn.
for steps : 1..100 % send the pattern 100 times
for i : 0..3
parallelput(16*(2**i)) % set the correct pin high
delay(100) % delay 1 tenth of a second

Creating an Electromagnet
Things to remember about electromagnets:
• The more coils you make, the stronger the magnet.
• Magnet wire works better, because it is thinner and more coils you can get.
• A soft iron core will make the magnet work better (a bolt).
Attach wire ends
to your interface
Wrap magnet wire
around the soft
iron core (bolt)
