Each road is associated with a value indicating the level of danger in maintaining that road during winter months. There are many subsets of roads such that the roads in such subsets keep the towns connected directly or indirectly. Each subset is assigned a cost of maintenance, which is directly proportional to the highest danger level of the road present in that subset. The engineer wants to select the smallest subset that keeps the towns connected directly or indirectly and that also has the lowest cost of maintenance. Develop an algorithm to find such a subset. Justify the correctness of your algorithm and derive its runtime.

Create a procedure named STATUS_SHIP_SP that allows an employee in the Brewbeans' Shipping Department to update an order status to add shipping information. The BB_BASKETSTATUS table lists events for each order so that a shopper can see the status, date, and comments as each stage of the order process is finished. The IDSTAGE column of the BB_BASKETSTATUS table identifies each stage; the value 3 in this column indicates that an order has been shipped. The procedure should allow adding a row with an IDSTAGE of 3, date shipped, tracking number and shipper. The BB_STATUS_SEQ sequence is used to provide a value for the primary key column. Test the procedure with the following information: o Basket # = 3 o Date shipped = 20-FEB-12 o Shipper = UPS o Tracking # = ZW2384YXK4957

Explanation:

A procedure named STATUS_SHIP_SP that allows an employee in the Brewbeans' Shipping Department to update an order status to add shipping information is in the explanation part below.

A representative from Brewbeans' shipping division can change an order's status and add shipment details by using the PL/SQL method STATUS_SHIP_SP, as shown in the following example:

CREATE OR REPLACE PROCEDURE STATUS_SHIP_SP (

   p_basket_number   IN  NUMBER,

   p_date_shipped    IN  DATE,

   p_shipper         IN  VARCHAR2,

   p_tracking_number IN  VARCHAR2

)

IS

   v_status_id   NUMBER;

BEGIN

   -- Get the next value from the BB_STATUS_SEQ sequence

   SELECT BB_STATUS_SEQ.NEXTVAL INTO v_status_id FROM DUAL;

   

   -- Insert a new row into the BB_BASKETSTATUS table

   INSERT INTO BB_BASKETSTATUS (STATUSID, BASKETNO, IDSTAGE, STATUSDATE, COMMENTS)

   VALUES (v_status_id, p_basket_number, 3, p_date_shipped, 'Shipped: ' || p_shipper || ', Tracking Number: ' || p_tracking_number);

   

   -- Commit the transaction

   COMMIT;

   

   -- Display a success message

   DBMS_OUTPUT.PUT_LINE('Order status updated. Shipment information added.');

EXCEPTION

   WHEN OTHERS THEN

       -- Display an error message

       DBMS_OUTPUT.PUT_LINE('Error: Unable to update order status.');

       -- Rollback the transaction

       ROLLBACK;

END;

/

Thus, by doing this, the procedure will be called with the specified parameters, and if successful, a new entry with the proper shipping information for basket number 3 will be added to the BB_BASKETSTATUS database.

discuss the communicatin process giving detailed explanation on each process​

Answers

Communications is fundamental to the existence and survival of humans as well as to an organization. It is a process of creating and sharing ideas, information, views, facts, feelings, etc. among the people to reach a common understanding. Communication is the key to the Directing function of management.

A manager may be highly qualified and skilled but if he does not possess good communication skills, all his ability becomes irrelevant. A manager must communicate his directions effectively to the subordinates to get the work done from them properly.

Communications Process

Communications is a continuous process which mainly involves three elements viz. sender, message, and receiver. The elements involved in the communication process are explained below in detail:

1. Sender

The sender or the communicator generates the message and conveys it to the receiver. He is the source and the one who starts the communication

2. Message

It is the idea, information, view, fact, feeling, etc. that is generated by the sender and is then intended to be communicated further.

Browse more Topics under Directing

Introduction, Meaning, Importance & Principles of DirectingElements of DirectionIncentivesLeadership

3. Encoding

The message generated by the sender is encoded symbolically such as in the form of words, pictures, gestures, etc. before it is being conveyed.

4. Media

It is the manner in which the encoded message is transmitted. The message may be transmitted orally or in writing. The medium of communication includes telephone, internet, post, fax, e-mail, etc. The choice of medium is decided by the sender.

5. Decoding

It is the process of converting the symbols encoded by the sender. After decoding the message is received by the receiver.

6. Receiver

He is the person who is last in the chain and for whom the message was sent by the sender. Once the receiver receives the message and understands it in proper perspective and acts according to the message, only then the purpose of communication is successful.

7. Feedback

Once the receiver confirms to the sender that he has received the message and understood it, the process of communication is complete.

8. Noise

It refers to any obstruction that is caused by the sender, message or receiver during the process of communication. For example, bad telephone connection, faulty encoding, faulty decoding, inattentive receiver, poor understanding of message due to prejudice or inappropriate gestures, etc.

Write a function remove_duplicates that removes duplicates from an array. For example, if remove_duplicates is called with an array containing 1, 4, 9, 16, 9, 7, 4, 9, 11 … then the array is changed to 1, 16, 7, 4, 9. 11. Your function should have a reference parameter for the array size that is updated when removing the duplicates

Answers

The function is an illustration of loops

Loops are used to perform repetitive operations

The function in Java where comments are used to explain each line is as follows:

//This defines the remove_duplicates function

public static int remove_duplicates(int arr[], int n){

 //If the length of the array is 0 or 1, then return the original array

 if (n == 0 || n == 1) {

  return n;

 }

 //This creates a new array

 int[] newArr = new int[n];

 

 //This initializes the index of the array to 0

 int ind = 0;

 //This iterates through the original array

 for (int i = 0; i < n - 1; i++) {

     //The following loop populates the new array with the unique elements of the original array

  if (arr[i] != arr[i + 1]) {

   newArr[ind++] = arr[i];

  }

 }

 newArr[ind++] = arr[n - 1];

 // The following loop changes the original array

 for (int i = 0; i < ind; i++) {

  arr[i] = newArr[i];

 }

 return ind;

}

At the end of the function, the duplicate elements of the array are removed

How to Set Up a Home Network- Beginners Guide

Today almost every home and small office has a local network, and an Internet connection.

The home network or small area network enables multiple devices e.g. PCs,tablets etc to connect to each other, and also to connect to the internet.

In this tutorial you will learn how you to build and setup a home or small area network and connect it to the Internet.

Explanation:

Choosing a Wired or Wireless Network

Do You Build a wired or Wireless Network? which is best?

Early (pre 2008) home networks were predominately wired networks.

Wired networks use Ethernet over UTP cable and tend to be faster than wireless networks, which is an important consideration if you are a gamer. The simple wired home network diagram below shows a minimum setup with a switch and broadband router.

Wired Network Advantages

Fast typically 100 Mbps to 10 Gbps

Secure and reliable.

Wired Network Dis-Advantages

Doesn’t work with devices that don’t have an Ethernet port e.g. tablets and smart phones.

Not so easy and fast to setup as it requires running cables. However Homeplug or powerline adapters can be used instead.

Not so easy for visitors and mobile devices (laptops) to connect to.

Main Uses

It Is best used for network backbone i.e. connecting between router,network switches and wireless access points on different levels (floors).
