Dijkstra's Algorithm in C

This code implements Dijkstra's algorithm to find the shortest path from a source vertex to all other vertices in a graph represented as an adjacency matrix. The program reads graph data from an input.txt file and writes the results to an output.txt file.

Code Implementation

#include <stdio.h>
#include <limits.h>
#include <stdbool.h>

#define MAX_VERTICES 100

// Function to find the vertex with minimum distance
int minDistance(int dist[], bool visited[], int vertices) {
    int min = INT_MAX, min_index;

    for (int v = 0; v < vertices; v++)
        if (!visited[v] && dist[v] <= min) {
            min = dist[v];
            min_index = v;
        }

    return min_index;
}

The Ancient Monuments and Archaeological Sites and Remains (AMASR) Act

The Ancient Monuments and Archaeological Sites and Remains (AMASR) Act is an important piece of legislation in India that aims to preserve and protect the country's rich heritage and cultural assets.

• The act was passed in 1958 and has since undergone several amendments to keep pace with changing times.

Overview of the AMASR Act

The AMASR Act defines an "ancient monument" as any structure or building, cave, sculpture, inscription, or monolith that is of historical, archaeological, or artistic interest.

• The act aims to protect such monuments and ensure their preservation for future generations.
• It applies to all monuments that are over 100 years old, whether they are in public or

Environment Protection Act (EPA) of 1986

India's original Constitution did not contain any provision for the protection of the natural environment. However, the Fundamental Duties, which were added by the 42nd Amendment to the Constitution, prescribed the protection of the environment, including forests, lakes, rivers, and wildlife, as a duty of the citizens of the country.

This amendment also added new Directive Principles of State Policy, one of which was Article 48A, which directed the State to protect and improve the environment and to safeguard forests and wildlife.

These developments were a result of the United Nations Conference on Human Environment, held in Stockholm in 1972. First, the Wildlife Protection Act 1972 was enacted. Then, the... Continue reading "Environment Protection Act 1986: Key Provisions & Aims" »

Curriculum Development

Curriculum development is the process of constructing, collecting, or assimilating content material and learning experiences for learners.

According to Roger and Taylor, "Curriculum development describes all the ways in which a training or teaching organization plans and guides learning. This learning can take place in groups or individually, inside or outside a classroom, and in institutional settings like schools, colleges, or training centers. It is central to the teaching and learning process."

Curriculum development involves activities such as:

• Conceptualizing the curriculum.
• Selecting and organizing content material or learning experiences.
• Suggesting methods and ways of providing these experiences.
• Evaluating learning

Factors Affecting Reaction Rates

Concentration

Increasing the concentration increases the probability of a collision between reactant particles. With more particles in the same volume, collisions are more frequent, speeding up the reaction rate. Conversely, a lower concentration leads to fewer collisions and a slower reaction rate.

Surface Area

If a solid reactant or catalyst is broken down into smaller pieces, the rate of reaction increases. This is because smaller pieces of the same mass have a greater surface area, providing more opportunities for reactant particles to collide with the surface and react.

Types of Rate Laws

Differential Rate Law: Describes how the rate of a reaction depends on the concentration of reactants (often simply called... Continue reading "Factors Affecting Reaction Rates and Rate Laws" »

Internet Technologies

The internet relies on several key technologies:

• Transmission Control Protocol (TCP): Enables connections and data exchange between hosts.
• Internet Protocol (IP): A unique 32-bit numeric address for each computer, represented by four numbers (0-255) separated by periods.
• Domain Name System (DNS): Converts domain names (e.g., google.com) to IP addresses.
• Hypertext Transfer Protocol (HTTP): The standard for transferring web pages.
• Hypertext Markup Language (HTML): Formats documents and links to other resources.
• Uniform Resource Locator (URL): References a web resource's location and retrieval method.

Cloud Computing

Cloud computing provides access to shared computing resources over a network. Different service models exist:
