Bubble Sort Algorithm in Java

Bubble Sort is a fundamental sorting algorithm that repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order. It is known for its simplicity, though it is inefficient for large lists.

import java.util.Scanner;

class program {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter number of elements: ");
        int n = sc.nextInt();
        int arr[

Java Program: Convert String to Uppercase

This simple Java program demonstrates how to use the built-in toUpperCase() method of the String class.

public class UpperCase
{
    public static void main(String[] args)
    {
        String str = "hello world";
        System.out.println(str.toUpperCase());
    }
}

Java Bytecode and Platform Independence

Defining Java Bytecode

Java Bytecode is the intermediate code generated by the Java compiler after compiling a Java program. When you write a Java source file (.java) and compile it using javac, the compiler converts it into a bytecode file (.class). This bytecode is not specific to any machine and can be executed by the Java Virtual Machine (JVM) on any platform.

Justification for Platform Independence

Platform independence means that a Java program can run on

Java Core Features and Characteristics

Java is renowned for its robust set of features that make it suitable for enterprise-level development:

  • Object-Oriented: Java strictly follows OOP principles: encapsulation, inheritance, polymorphism, and abstraction.
  • Platform-Independent: Java runs on any system equipped with a Java Virtual Machine (JVM), adhering to the “Write Once, Run Anywhere” (WORA) philosophy.
  • Simple and Easy to Learn: Java simplifies development by eliminating complex features found in

Thermal Ionization Mass Spectrometry: Precision Isotope Analysis

Posted by on Aug 22, 2025 in Computer Engineering in Information Technologies Engineering | 0 comments

Thermal Ionization Mass Spectrometry (TIMS)

TIMS stands for Thermal Ionization Mass Spectrometry, a highly precise analytical technique used to determine the isotopic composition and concentration of elements in a sample. It is especially valuable in fields like geochemistry, nuclear science, and environmental science.

Principle of TIMS

TIMS works by thermally ionizing a sample on a hot filament and then analyzing the resulting ions based on their mass-to-charge ratio (m/z). The ions are separated
