This document provides information about logic gates and Boolean expressions:
- It defines common logic gates (AND, OR, NOT) and their truth tables. It also introduces more complex gates like NAND and NOR.
- It explains how to write Boolean expressions, evaluate them using truth tables, and draw the corresponding logic circuits.
- Examples are provided for writing Boolean expressions for given logic circuits, drawing circuits for given expressions, and evaluating expressions using truth tables.
- The purpose is for students to understand basic logic gates, Boolean expressions, and how to represent logic relationships in circuits.

This is the project that describes each logic gate briefly. This includes AND , OR, NOT, NOR, NAND,XOR. Each gate has the symbol, working, boolean formula and the observation table.
this project requires breadboard, single stranded wire, battery pack(d.c.) , multimeter and finally their applications.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

6. Logic Gates
•
An electronic circuit operates on one or
more input signals to produce an output
signal.
Gates are digital (two-state, On and Off)
circuits and can be analyzed with Boolean
algebra•
7. The three basic logic gates are :
AND gate OR gate NOT gate
Logic Gates
9. Truth
Table
● A truth table is a good way to show the function of a
logic gate.
● It shows the output states for every possible
combination of input states
● The symbols of 1 (True) or 0 (False) are used
● For a logic gate with n inputs, there are 2n entries in
the truth table
● Eg : A logic gate with 3 inputs will have 8 entries
(2n=8)
10. STEP BY STEP CREATING A BASIC TRUTH TABLE
1. Identify how many input (n) form the given Boolean expression
and logic circuit.
2. Determine number of entry (2n)
