Edgar Allen Poe :: essays research papers

EDGAR ALLEN POE BIOGRAPHY Edgar Allen Poe was born in 1809 in Boston. His stories were about love and sadness. He died when he was 40 years old in 1849. People said that they found him unconscious and believed him drunk. He was an excellent writer that kept people fascinated with stories. He died as he lived all his life was miserable and with out hope. It believed that he uses a drug named opium that helped him use his imagination and he uses alcohol. Those were his inspirations and his story's that were so fabulous come from there. These things were making him crazy and took him out of control. A thing that made him even more crazy is that everyone he had ever met or loved always semmed to have died from a disease called tuberculosis. This made him very depressive also.

Difference Between Single & Married People Essay

Today, there are a lot of significant numbers of people who are married and some are single. This has changed their lives and gives differences between their lives. In this essay, I am going to compare and contrast the differences between single people’s lives and married people’s lives in their lifestyle, companionship, and responsibility. Some things in life are going to be good, regardless of whether you are single or married, and some things will be the opposite. There are advantages and disadvantages to both. The two areas that differ in married and single life are compromise and sharing of possessions. Lifestyle is the first difference between single and married people’s lives. Single people have much more privacy in their life. They are not bothered by anybody in their home. Nobody will demand that they sleep late, not watch movies too much and so on. And, single people can live a free life too. They can spend their time with their friends anywhere and anytime they want. In contrast, married people are bothered by their partner. They have to take care of their children and their partner. They cannot live a free life. If they want to go out with their friends, they must get permission from their partner first before they go. Married people are busier compared to single people, because married people have to take care of their children and their partner, unlike single people who do not have children and partner. Companionship is the next difference between single and married people’s lives. A husband depends on his wife, and a wife depends on her husband. Support is easily achieved from their partners, parents and their children, unlike single people who do not depend on anybody in this world. They cannot trust anyone to share their secrets and other important parts of their life except their parents. Support can be achieved only from their parents and their friends. Read more:Â  Married vs Single Responsibility is the last difference between single and married people’s lives. Married people have to manage their money and expenses gently and economically every day. They are also responsible for raising their children and guiding their families. If they cannot guide their family in the right way, their family can be broken and maybe ruined their lives. Married people are also responsible for managing their time. They have to spend their time with their children, husband or wife every day. In contrast, people who remain single do not have a schedule, they do not have any children or partners to guide and they are less responsible with their money and daily expenses. In conclusion, lifestyle, companionship, and responsibility are the three main differences between single people and married people’s lives. So is single life comfort and married life pleasure? Some people prefer to be single, others prefer marriage. Although there are reasonable advantages to both lifestyles, both lifestyles can be equally rewarding.

Introduction Of The Antenna Systems - 4702 Words

INTRODUCTION 1.1 Antenna Systems: Depending on the number of antennas used in the transmitting and receiving sections, the systems are divided into 4 types. 1.1.1 SINGLE INPUT SINGLE OUTPUT (SISO): Fig 1.1.1: SISO In SISO, there will be only single transmitter and a single receiver. This is the general system which we use. The simplest antenna technology is SISO. In some environments, this system is vulnerable to problems caused by multipath effects. When an electromagnetic field (EM field) is met with obstructions such as hills, buildings, utility wires, and canyons the wavefronts are scattered, and thus it take multi paths to reach the destination. Fading, cut-out (cliff effect), and intermittent reception (picket fencing) are the problems caused by late arrival of scattered portion of signals. In a digital communications system, it cause a reduction of data speed and number of errors is increased. In order to eliminate or minimize problems caused by multipath wave propagation, a new technology has been introduced and it is Smart Antenna Technology. There are three forms of smart antenna, known as SIMO (single input, multiple output), MISO (multiple input, single output), and MIMO (multiple input, multiple output). 1.1.2 SINGLE INPUT MULTIPLE OUTPUT (SIMO) : Fig 1.1.2 : SIMO In SIMO, there will be only single transmitter and many receivers. 1.1.3. MULTIPLE INPUT MULTIPLE OUTPUT ( MISO): Fig. 1.1.3 : MISO In MISO there will be multiple transmitters and aShow MoreRelatedWireless Local Area Network Technology Project Analysis1127 Words   |  5 Pagespatch antenna with enhanced bandwidth and gain.
