1.Define Pixel and resolution. Explain in brief about Back face detection algorithm.
==A pixel (short for picture element) is the smallest unit of a digital image or display screen. It represents a single point in a raster image and has a specific color and intensity. //Resolution refers to the number of pixels in an image or display, usually written as width × height (e.g., 1920×1080).Higher resolution means more pixels, which leads to sharper and more detailed images.

What is Leadership?
MOTO: “BE EASY TO FOLLOW”
Today’s leadership job is to coach, chart the path, clear the path, and help people have awesome experiences in the process.
Followership
Followership is the complement to leadership. Leadership is the complement to followership. They are separate roles but they are inseparable.
Two main lessons
Leadership and followership work best together
The most effective leadership happens when the goal is desired by the follower(s).
Short Notes:
(a) Service Led growth
Service-led growth refers to economic growth driven primarily by the service sector, which includes industries like finance, IT, tourism, and healthcare. This type of growth is characterized by a significant contribution of services to the GDP, often surpassing the contributions of the primary and secondary sectors.
(b) Primary sector
The primary sector involves the extraction and production of raw materials, such as agriculture, forestry, fishing, and mining.

What is Information Security? Information security means protecting data from stealing, changing, destroying, disclosing, or denying access. It has traditionally relied on physical measures (like locked cabinets) and administrative controls (such as personnel screening). Even today, some reliance on physical security remains. Modern Information Security Needs: Due to increased computer use, automated tools are now needed to protect stored information. As network use grows, it has become essential...
Register Transfer Language (RTL) is a symbolic notation used to describe the micro-operations in digital systems, specifically those involving registers and data movement. It provides a way to express the transfer of data between registers, along with the control conditions that trigger those transfers.
RTL uses arrow notation to represent transfer. For example, the statement R1 ← R2 indicates that the content of register R2 is transferred to register R1. RTL statements are generally governed
Pathways: MAPK: promotes cell growth, proliferation, differentiation, survival, and resistance to apoptosis: Raf->Ras->MKK->ERK->RSK->RSK (in nucleus)->CREB
BRCA1: Repairing double-strand DNA breaks through homologous recombination, controlling cell cycle checkpoints, and helping prevent harmful mutations from accumulating.
Capsases: enzymes that destroy the cell (key role in apoptosis): initiator procaspases aggregate->activate each other->initiates cytochrome-c to release
...Metallurgical sample preparation for microscopy is a crucial step in analyzing the microstructure and
properties of metallic materials. Proper sample preparation is essential to obtain accurate and
meaningful results. The process involves several steps:
1. Selection of the Sample: Choose a representative portion of the material to be analyzed.
Ensure that the sample is free from external contaminants and has a flat surface for
preparation.
2. Cutting: Use a precision cutting method to obtain a small...
