Metal Matrix Composites (MMCs)

Metal matrix composites (MMCs) can be classified based on the type of metal used as the matrix. The classification of metals in MMCs includes:

1. Pure Metals: These are metals composed of a single element, such as aluminum (Al), copper (Cu), titanium (Ti), or magnesium (Mg). Pure metals can serve as matrices in MMCs, providing specific properties and characteristics.
2. Intermetallic Compounds: Intermetallics are compounds formed by the combination of two or more metallic elements. They possess a distinct crystal structure and can exhibit unique properties. Intermetallic compounds, such as titanium aluminides (Ti-Al) or nickel aluminides (Ni-Al), can be used as matrices in MMCs.
3. Alloys: Alloys are metallic materials composed

Advantages of Computer-Assisted Psychological Assessment

1. Item Banking

Computer-assisted assessment allows for the creation and maintenance of item banks, which are databases of test items that can be used across multiple assessments. This facilitates efficient test development and administration, as psychologists can select items from the item bank to create customized tests for specific purposes or populations.

2. Item Branching

Computerized assessments can utilize item branching, which means that the subsequent items presented to the individual can be tailored based on their previous responses. This adaptive testing approach allows for more efficient and targeted assessments, as the system can dynamically select items based on the individual'...

Problem Statement

Explore the usage of basic Linux system calls.

Process Management System Calls

The system calls to manage processes are:

• fork(): Used to create a new process.
• exec(): Executes a new program.
• wait(): Waits until the process finishes execution.
• exit(): Exits from the process.

System calls used to get process IDs are:

• getpid(): Gets the unique process ID of the process.
• getppid(): Gets the parent process's unique ID.

Stat System Call

The stat system call retrieves information about files, specifically from their inodes. For instance, to get a file's size and name, you would typically use stat. Let's illustrate with a C code snippet (src/ls1.c):

#include<stdio.h>
#include<dirent.h>
#include<cstdlib>

struct dirent *dptr;
