The document discusses the bipolar junction transistor (BJT), an important electronic device invented in 1947 at Bell Labs by Bardeen, Brattain, and Shockley. It summarizes the BJT's construction using either PNP or NPN semiconductor materials, its basic working involving forward and reverse biasing of the base-emitter and collector-emitter junctions, and its three main modes of operation - cutoff, saturation, and active. The document also covers BJT configurations like common base, common collector, and common emitter; and concludes with references.

The performance obtainable from a single-stage amplifier is often insufficient for many applications, hence several stages may be combined forming a multistage amplifier. These stages are connected in cascade, i.e. output of the first stage is connected to form input of second stage, whose output becomes input of third stage, and so on.

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.

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.

Transistor is considered one of the most important invention of the 20th century replacing the vaccum tubes. Invented at the Bell Labs, United state by John Bardeen, Wesley Brattain and William Shockley in 1947 a transistor is used to amplify signals and acts as a switch in electronic devices
It consists of a lightly doped n type material called the Base which is sandwiched between two heavily doped P type material. Upper p type material is made physically larger so as to handle a large amount of current and this constitutes the collector. The lower semiconductor material constitutes the emitter. This is the basic construction of a pnp type transistor which is usually represented by a round symbol consisting of three terminals with an arrow pointing towards the base in the emitter section signifying that it is a pnp type transistor
Similarly we can have an NPN type transistor as shown in the illustration. In this case the p type material is sandwiched between two N-type material. This is again represented by the round symbol consisting of three terminals with an arrow pointing out of the base in the emitter section signifying that it is an npn-type transistor
