1) Logic gates like AND, OR, NOT, NAND, and NOR are basic digital circuits that perform logical operations on binary inputs and produce binary outputs. Their behavior is defined by truth tables.
2) AND gates output 1 only when all inputs are 1. OR gates output 1 if any input is 1. NAND and NOR gates are universal gates that can be used to implement all other logic functions.
3) Computers use binary number systems like decimal to represent data as strings of 0s and 1s. Decimal uses 10 digits while the position of each digit determines its value and meaning in base-10 numbers.
Here in this slides information about all Logic gates with symbol, circuit and truth tables.
Logic gates are devices that can combine multiple inputs at independent logic levels and come up with an output accordingly. There are many kinds of logic gates, and the distinction lies in that each kind processes the inputs differently, and may give different outputs for the same inputs.
The way the logic gate processes different inputs is given in a truth table for that gate, which lists all the possible combinations of inputs next to their outputs. An example is given for a simple one-input gate with the function of giving the opposite logic level at the output to the one at the input. The inputs are given on the left, and the outputs are on the right. Generally, the inputs are called A, B, C, etc., and the output is labelled Q. In this case, there are only two possible inputs, 1 or 0, but logic gates can have any number of inputs.

An Approach to Detecting Writing Styles Based on Clustering Techniques
Authors:
-Devkinandan Jagtap
-Shweta Ambekar
-Harshit Singh
-Nakul Sharma (Assistant Professor)
Institution:
VIIT Pune, India
Abstract:
This paper proposes a system to differentiate between human-generated and AI-generated texts using stylometric analysis. The system analyzes text files and classifies writing styles by employing various clustering algorithms, such as k-means, k-means++, hierarchical, and DBSCAN. The effectiveness of these algorithms is measured using silhouette scores. The system successfully identifies distinct writing styles within documents, demonstrating its potential for plagiarism detection.
Introduction:
Stylometry, the study of linguistic and structural features in texts, is used for tasks like plagiarism detection, genre separation, and author verification. This paper leverages stylometric analysis to identify different writing styles and improve plagiarism detection methods.
Methodology:
The system includes data collection, preprocessing, feature extraction, dimensional reduction, machine learning models for clustering, and performance comparison using silhouette scores. Feature extraction focuses on lexical features, vocabulary richness, and readability scores. The study uses a small dataset of texts from various authors and employs algorithms like k-means, k-means++, hierarchical clustering, and DBSCAN for clustering.
Results:
Experiments show that the system effectively identifies writing styles, with silhouette scores indicating reasonable to strong clustering when k=2. As the number of clusters increases, the silhouette scores decrease, indicating a drop in accuracy. K-means and k-means++ perform similarly, while hierarchical clustering is less optimized.
Conclusion and Future Work:
The system works well for distinguishing writing styles with two clusters but becomes less accurate as the number of clusters increases. Future research could focus on adding more parameters and optimizing the methodology to improve accuracy with higher cluster values. This system can enhance existing plagiarism detection tools, especially in academic settings.

The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.
Online aptitude test management system project report.pdfKamal Acharya
The purpose of on-line aptitude test system is to take online test in an efficient manner and no time wasting for checking the paper. The main objective of on-line aptitude test system is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves lot of time but also gives fast results. For students they give papers according to their convenience and time and there is no need of using extra thing like paper, pen etc. This can be used in educational institutions as well as in corporate world. Can be used anywhere any time as it is a web based application (user Location doesn’t matter). No restriction that examiner has to be present when the candidate takes the test.
Every time when lecturers/professors need to conduct examinations they have to sit down think about the questions and then create a whole new set of questions for each and every exam. In some cases the professor may want to give an open book online exam that is the student can take the exam any time anywhere, but the student might have to answer the questions in a limited time period. The professor may want to change the sequence of questions for every student. The problem that a student has is whenever a date for the exam is declared the student has to take it and there is no way he can take it at some other time. This project will create an interface for the examiner to create and store questions in a repository. It will also create an interface for the student to take examinations at his convenience and the questions and/or exams may be timed. Thereby creating an application which can be used by examiners and examinee’s simultaneously.
Examination System is very useful for Teachers/Professors. As in the teaching profession, you are responsible for writing question papers. In the conventional method, you write the question paper on paper, keep question papers separate from answers and all this information you have to keep in a locker to avoid unauthorized access. Using the Examination System you can create a question paper and everything will be written to a single exam file in encrypted format. You can set the General and Administrator password to avoid unauthorized access to your question paper. Every time you start the examination, the program shuffles all the questions and selects them randomly from the database, which reduces the chances of memorizing the questions.
2. AND Gate
• An AND gate is a digital circuit that has two or more inputs and
produces an output, which is the logical AND of all those inputs.
• It is optional to represent the Logical AND with the symbol ‘.’
• The following table shows the truth table of 2-input AND gate.
A B Y = A.B
0 0 0
0 1 0
1 0 0
1 1 1
3. AND Gate
• A, B are the inputs and Y is the output of two input AND gate. If both
inputs are ‘1’, then only the output, Y is ‘1’. For remaining combinations of
inputs, the output, Y is ‘0’.
• The following figure shows the symbol of an AND gate, which is having
two inputs A, B and one output, Y. This AND gate produces an output Y,
which is the logical AND of two inputs A, B. Similarly, if there are ‘n’
inputs, then the AND gate produces an output, which is the logical AND of
all those inputs. That means, the output of AND gate will be ‘1’, when all
the inputs are ‘1’
4. OR gate
• An OR gate is a digital circuit that has two or more inputs and
produces an output, which is the logical OR of all those inputs.
This logical OR is represented with the symbol ‘+’.
A B Y = A + B
0 0 0
0 1 1
1 0 1
1 1 1
5. • A, B are the inputs and Y is the output of two input OR gate.
• If both inputs are ‘0’, then only the output, Y is ‘0’. For remaining
combinations of inputs, the output, Y is ‘1’.
• This OR gate produces an output Y, which is the logical OR of two
inputs A, B. Similarly, if there are ‘n’ inputs, then the OR gate
produces an output, which is the logical OR of all those inputs.
• That means, the output of an OR gate will be ‘1’, when at least one of
those inputs is ‘1’.
6. NOT gate
• A NOT gate is a digital circuit that has single input and
single output. The output of NOT gate is the logical
inversion of input. Hence, the NOT gate is also called
as inverter.
A Y = A’
0 1
1 0
7. Universal gates
• NAND & NOR gates are called as universal gates. Because we
can implement any Boolean function, which is in sum of
products form by using NAND gates alone.
• Similarly, we can implement any Boolean function, which is
in product of sums form by using NOR gates alone
• NAND gate is a digital circuit that has two or more inputs and
produces an output, which is the inversion of logical AND of
all those inputs.
• The following table shows the truth table of 2-input NAND
gate
8. NAND GATE A B Y = (A.B)’
0 0 1
0 1 1
1 0 1
1 1 0
• Here A, B are the inputs and Y is the output of two input
NAND gate.
• When both inputs are ‘1’, the output, Y is ‘0’.
• If at least one of the input is zero, then the output, Y is ‘1’.
This is just opposite to that of two input AND gate operation.
• The image shows the symbol of NAND gate, which is having
two inputs A, B and one output, Y.
9. NOR gate
• NOR gate is a digital circuit that has two or more
inputs and produces an output, which is the inversion
of logical OR of all those inputs.
A B Y = (A+B)’
0 0 1
0 1 0
1 0 0
1 1 0
10. Special Gates
• Ex-OR & Ex-NOR gates are called as special gates. Because, these two
gates are special cases of OR & NOR gates.
• Ex-OR gate
• The full form of Ex-OR gate is Exclusive-OR gate. Its function is same
as that of OR gate except for some cases, when the inputs having
even number of ones.
• The following table shows the truth table of 2-input Ex-OR gate.
11. Ex-OR gate
A B Y = A⊕B
0 0 0
0 1 1
1 0 1
1 1 0
• Here A, B are the inputs and Y is the output of two input Ex-OR gate. The truth
table of Ex-OR gate is same as that of OR gate for first three rows. The only
modification is in the fourth row.
• That means, the output Y is zero instead of one, when both the inputs are one,
since the inputs having even number of ones. Therefore, the output of Ex-OR
gate is ‘1’, when only one of the two inputs is ‘1’. And it is zero, when both
inputs are same.
15. Number System
• When we type some letters or words, the computer translates
them in numbers as computers can understand only numbers.
• A computer can understand the positional number system
where there are only a few symbols called digits and these
symbols represent different values depending on the position
they occupy in the number.
• The value of each digit in a number can be determined using −
• The digit
• The position of the digit in the number
• The base of the number system (where the base is defined as the total
number of digits available in the number system)
16. Decimal Number System
• The number system that we use in our day-to-day life is the
decimal number system.
• Decimal number system has base 10 as it uses 10 digits from 0
to 9. In decimal number system, the successive positions to the
left of the decimal point represent units, tens, hundreds,
thousands, and so on.
17. Each position represents a specific power of the base (10). For
example, the decimal number 1234 consists of the digit 4 in the
unit's position, 3 in the tens position, 2 in the hundreds position, and
1 in the thousands position. Its value can be written as
