1 - Create your first class with name 'conn' and paste the code below in it


 package Employeee;

import java.sql.*;

public class conn{
  
    public Connection c;
    public Statement s;

    public conn(){
        try{
            Class.forName("com.mysql.jdbc.Driver");
            c = DriverManager.getConnection("jdbc:mysql:///project3","root","");
            s = c.createStatement();
        }catch(Exception e) {
            e.printStackTrace();
        }
    }
}
 




2 - Create second class with name 'Login' and paste the code below in it



package Employeee;

import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.sql.*;

class login  implements ActionListener{

How to Print Tree in Python??


it is very simple in python to print tree than in java

I tried to use the minimum code to fulfill the requirements. the code is of only 2 lines.

find the code below


for i in range(1,10):

Yagi-Uda antenna is the most commonly used type of antenna for TV reception over the last few decades. It is the most popular and easy-to-use type of antenna with better performance, which is famous for its high gain and directivity.

Frequency range
The frequency range in which the Yagi-Uda antennas operate is around 30 MHz to 3GHz which belong to the VHF and UHF bands.

Construction of Yagi-Uda Antenna

A Yagi-Uda antenna was seen on top of almost every house during the past decades. The parasitic elements and the dipole together form this Yagi-Uda antenna.
Construction Yagi-Uda Antenna
The figure shows a Yagi-Uda antenna. It is seen that there are many directors placed to increase the directivity of the antenna. The feeder is the folded dipole. The reflector is the lengthy element, which is at the end of the structure.
Yagi-Uda Antenna
The figure depicts a clear form of the Yagi-Uda antenna. The center rod like structure on which the elements are mounted is called as boom. The element to which a thick black head is connected is the driven element to which the transmission line is connected internally, through that black stud. The single element present at the back of the driven element is the reflector, which reflects all the energy towards the direction of the radiation pattern. The other elements, before the driven element, are the directors, which direct the beam towards the desired angle.

Designing of yagi uda antenna

#knowledge #stream #blog
For this antenna to be designed, the following design specifications should be followed.
Designing
They are −
ELEMENTSPECIFICATION
Length of the Driven Element0.458λ to 0.5λ
Length of the Reflector0.55λ to 0.58λ
Length of the Director 10.45λ
Length of the Director 20.40λ
Length of the Director 30.35λ
Spacing between Directors0.2λ
Reflector to dipole spacing0.35λ
Dipole to Director spacing0.125λ
If the specifications given above are followed, one can design an Yagi-Uda antenna.

Radiation Pattern for Yagi Uda Antenna

#knowledge #stream #blog
The directional pattern of the Yagi-Uda antenna is highly directive as shown in the figure given below.
Horizontal vertical Pattern
The minor lobes are suppressed and the directivity of the major lobe is increased by the addition of directors to the antenna.

Advantages of Yagi Uda

The following are the advantages of Yagi-Uda antennas −
  • High gain is achieved.
  • High directivity is achieved.
  • Ease of handling and maintenance.
  • Less amount of power is wasted.
  • Broader coverage of frequencies.

Disadvantages of Yagi Uda

The following are the disadvantages of Yagi-Uda antennas −
  • Prone to noise.
  • Prone to atmospheric effects.

Applications

The following are the applications of Yagi-Uda antennas −
  • Mostly used for TV reception.
  • Used where a single-frequency application is needed.

Day 41 — BGP Confederations: Sub-AS Design, External View and Migration

1. Opening Confederations are another way to scale BGP inside a large administrative domain. They divide the domain into member autonomous systems while presenting a single confederation identifier to external peers. They are powerful, but their operational model is more complex than simply 'using private ASNs inside.' The engineering goal is not to memorize another BGP command. It is to understand what information each speaker is allowed to propagate, what path information can be hidden, and what failure domain is created by the chosen control-plane architecture . 2. Concept and standards behavior RFC 5065 defines AS_CONFED_SEQUENCE and AS_CONFED_SET and how member-AS relationships are represented. Confederation external sessions have eBGP-like properties inside the confederation, while the confederation is presented externally as one AS. Modern guidance must also account for the fact that RFC 9774 prohibits new origination of AS_SET/AS_CONFED_SET in ordinary aggregation c...
