The Mailbox And Postal System Information Technology Essay

The Mailbox And Postal System Information Technology Essay The hardware and software benefited in this project are the physical mailbox itself, a microcontroller, infrared sensors, and MySQL database management system. This chapter will give brief introduction of the mailbox and postal system, fundamental of microcontroller and sensor, and database management system (DBMS). 2.2 Mailbox and Postal System 2.2.1 Introduction of Mailbox Mailboxes are tools for sending letters (Postbox Solutions, 2007). They are very common in human communities. It provides people with one of the most practical way of communicating with other people around the world. There are so many varieties of mailbox regardless of shapes, colours, fonts, logo and etc. However, no matter how different or how strange the mailbox may look like, it still does its job with no compromises. 2.2.2 Relationship of Mailbox and Postal System in History Research by Cornerstone (2010) said that mailboxes is started to be used in the late 1700s in Paris, France. As time passed by, it became popular in the Europe in middle-late 1800s after the British Post Office asked people to install mailboxes at their offices and residents and decided to begin mail delivery. Previously, people have to pick their mails at the local post office by themselves and there were no postmen during that time. The story is different in the U.S in 1863 when the U.S. Postal Service (USPS) began the Free City Delivery. People in the U.S at that time had no mailboxes installed at their houses. Postmen delivered mail to each houses door by door waiting  for a patron  to answer the knock. This method of mail delivery took extra time and patrons were not always home or able to answer the door.  Patrons began to install mail slots and mailboxes at their doors. According to Cornerstone (2010), the U.S. Postal Service in 1896 introduced Rural Free Delivery (RFD). The USPS researched ways to save time and solve the problem with mail-carriers delivering mail to the scattered rural patrons.  They proposed that mailboxes for people lives in the area to be placed at curb sides and roadways. Later in 1923, USPS mandated that every household to have a  proper mailbox to receive mails. In 1915, Roy J. Joroleman, an employee of the post office invented the curved, tunnel-shaped mailbox.   The shaped was designed to prevent water and snow from collecting in the mailbox.  Soon after, the Postmaster General released the design for manufacture and production and this design has been the top-selling type of mailbox (Cornerstone, 2010). Figure 2.1 : A curved, tunnel-shaped mailbox 2.2.3 Centralize Mailbox System The development of the country has seen that there are so many tall, multiple-storey building been built all over the country. Single type mailbox that can always be spotted at each household and offices during the early days is no more practical for residential apartments and office complexes. In order to overcome this problem, centralize mailbox system was introduced. Centralized mailbox system often found at the ground floor of each tall building where every owner of each residential apartment or office will have one for his or her unit. central mailbox.PNG Figure 2.2 : Centralize mailbox system. 2.3 Microcontroller 2.3.1 Introduction to Microcontroller In simple words, a microcontroller is a computer (Brain, 2000). The terms computer can be wide in definition. It can be a desktop personal computer, a laptop computer, a handheld-sized smartphones or the microcontrollers themselves. A microcontroller can be interpreted as a computer due to the reason that it has several similarities as compared to a computer. Generally, the basic architecture of a microcontroller involves four main parts; central processing unit (CPU), random access memory (RAM), read-only memory (ROM), and input output ports (I/O ports). In the case of computers, all computers have a CPU that executes programmes such as a web browser or a word processor. The computer has some RAM installed where the CPU can store variables while doing its work. It also has I/O ports that connect many types of input and output devices, for example the keyboard the input device, and the monitor the output device. inside a microcontroller.PNG Figure 2.3 : The architecture of a microcontroller (Engineers Garage). However, with certain comparison in terms of features, microcontrollers and computers can be differentiated. The desktop computer which often can be found at offices and homes is a general purpose computer, while a microcontroller is a special purpose computer (Brain, 2000). Due to its relatively small size, microcontrollers are embedded inside some other devices and work as the controller of the features of the product. Microcontrollers are also dedicated to run one specific programme only; the programmed that is loaded into the ROM. Finally, often in most of the cases, a microcontroller is small and low in cost, hence good for mass production of products that utilize microcontrollers. 2.4 Sensor 2.4.1 Introduction to Sensor A sensor is a device that measures the physical quantity and converts it into a signal which can be read by an observer or an instrument. Ideal sensors are designed to be linear. The output signal of such a sensor is linearly proportional to the value of the measured property. The sensitivity is then defined as the ratio between output signal and measured property. A good sensor obeys the following rules: Is sensitive to the measured property. Is insensitive to any other property. Does not influence the measured property. 2.4.2 Applications of Sensor Sensors are widely used in our daily life nowadays. There are many types of sensors today. These sensors can be categorized into specific types. Lists of sensors use nowadays are as below: Acoustic sensor such as Geophone, Microphone and Seismometer. Electric current sensor such as Ammeter, Voltmeter and Multimeter. Environment and weather sensor such as Gas detector and Rain sensor. Optical, light and imaging sensor such as flame detector, Infra-red sensor and Photodiode. Pressure sensor such as Barometer, Hydrometer and Pressure sensor. Temperature sensor such as Thermometer. 2.5 Database 2.5.1 Introduction to Database The database is one of the technology terms that most people have become accustomed to hearing either at work or while surfing the internet. The database term used to be an extremely technical term. However, database has become a household term with the rise of computer systems and information technology throughout the culture. Selena (1998) has highlighted the definition of database as a computerized way of keeping collection of records or data. The true usefulness of database is seen especially if the data stored in the database in big volumes because the stored data is easily accessible. Moreover, adding new information and updating any changes should also be considerably painless. Besides that, on-demand record searching in the future will be piece of cake. Another advantage of a database is it can be shared all over the network where the computer that holds the database is connected. At this point, the presence of a Database Management System (DBMS) is very important in order to have a highly systematic database system. DBMS is a program that handles the queries and data stored inside the database. 2.5.2 Types of Databases There are four types of databases that are commonly used where each type of database represents its own data model. Data model means how the data inside the database is structured. The four types are; Flat Model, Hierarchical Model, Relational Model, and Network Model. 2.5.2.1 The Flat Model Database As written by Smith (2010), a flat database is a database that utilizes only one table for the fields of records. For example, a spreadsheet is used to store all the data and records. The information is separated into columns of its category, and each line represents one record. This type of database might be sufficient for small database, but a spreadsheet will seem to be not practical, notably for ones with large amount of records. 2.5.2.2 The Hierarchical Model Database As its name hints, the hierarchical model database resembles a hierarchically-arranged data (Selena, Introduction to Databases for the Web: Pt. 1, 1998). It links records together in a structure like a tree, or like an organizational chart. In this model, each data will be categorized and stored as a sub-data of its category. Every data must fall into only one category. Hierarchical structure database were widely implemented during the early time of database management systems. However, this model of database became irrelevant for some certain data types. For example, in a college environment, the administration might stored student information and sorts them according to their courses. Database operation will be smooth if every student is enrolled in one course only. But, problem will arise whenever a student enrolled in more than one course. Hierarchical database is unable to put a record into two categories, or otherwise, it will be considered as duplications. Figure 2.4 shows an example of the structure of hierarchical database. hierarcy engineering.png Figure 2.4 : The tree structure of hierarchical database model. 2.5.2.3 The Relational Model Database The relational model is the most popular type of database the most database system in use today. As appointed by K. Powell (2010), the relational database concept was derived from the principal of relational algebra, which was realized by Dr. E. F. Codd in his paper, A Relational Model of Data for Large Shared Data Banks. This database model is a very powerful tool, not only to store records, but to access it as well. All the data were stored in tables. Each table contains of rows and columns. A single record will be recorded in one row, and the details of the data are separated in columns, in the table. Every column has a unique name and the content within the column must be of the same type. A table is able to hold many records, and sometimes tables are referred as relation. A database may have more than one table. Each of the tables can be linked or related to each other by referring to the primary key. A primary key is a unique name that every record must have that acts as its identifier. 2.5.2.4 The Network Model Database A network database model is not far different from the hierarchical model. The difference between network and hierarchical model is, in network model, a record may fall into more than one category. Figure 2.5 shows the structure of network database model which is a bit different from relational database models. hierarcy engineering2.png Figure 2.5 : The structure of network database model. 2.6 MySQL 2.6.1 Introduction to MySQL MySQL is a probably the most popular database management system. Referring to the MySQL 5.0 Reference Manual (2010), to perform an operation onto a database such as adding, accessing, and processing data stored in a computer database, ones will need a database management system such as MySQL. A DBMS plays a central role in computers at handling large amounts of data. 200px-MySQL.svg.png Figure 2.6 : The MySQL logo. MySQL is a relational database management system or so called as RDBMS. For the sake of speed and flexibility, a relational database stores data in separate tables compared to flat file database that puts all the data in one big file. The SQL abbreviation in MySQL word stands for Structured Query Language (MySQL 5.0 Reference Manual, 2010). Badurina (2010) stated that MySQL is open source and it falls under GNU Not Unix (GNU) General Public License (GPL). Open source means that anyone is possible to use and modify the software.

Vioxx and Merck & Co. Essay -- essays research papers

Vioxx/Merck Summary The painkiller Vioxx was introduced in 1999 by Merck & Co. It has been used by over 20 million Americans since it was put on the market. Vioxx remained on the market for approximately five years without adequate warnings about its risks. In September of 2004, Merck took Vioxx off the market after a study revealed that it doubled the risk of heart attack or stroke for patients that used it for more than 18 months. Although Merck claimed that they had no idea of these possibly lethal side effects, some internal documents imply that they had been aware of the problem for years and had not made moves to change it. Over 300 lawsuits have been filed against Merck, and it is expected that thousands more will arise.   Ã‚  Ã‚  Ã‚  Ã‚  Further studies were conducted on the drug, but Merck adamantly fought Vioxx findings. Even thou Merck funded and agreed with the design of the study, it publicly discredited its findings. Other reports showed that in older patients, Vioxx made no provide as much protection as it is expected to. One study links Vioxx to 88,000 to140,000 cases of heart disease. Most of this information had been kept private for quite a long time.   Ã‚  Ã‚  Ã‚  Ã‚  Despite the obvious health risks, in February of 2005, government advisers concluded that the benefits of Vioxx outweighed the dangers and that it was the patients decision whether or not to keep using the drugs.

Analysis Of The Chimney Sweeper - 868 Words

â€Å"The Chimney Sweeper† William Blake wrote two poems with the same name but very different meanings. Two editions of â€Å"The Chimney Sweeper† were published in 1789 and 1794 as a response to the condition of the chimney sweeps. William Blake published â€Å"The Chimney Sweeper† in two separate parts-Songs of Innocence and Songs of Experience. William Blake wrote two versions of the same poem with differences in characterization, theme, and tone. The first poem of â€Å"The Chimney Sweeper† is Songs of Innocence. This poem is a dramatic monologue with the feel of a child-like nursery rhyme which contrasts the innocence of the speaker with the horrors that he is facing on a day-to-day basis. The speaker is a small boy who was sold into becoming a†¦show more content†¦In this poem, the speaker sees a young child covered in soot lying alone in the snow. The child informs the speaker of his parents forcing him to work in the chimneys and how he p uts on a facade of happiness in order to trick his parents into believing that they have not done him wrong. â€Å"And because I am happy, dance sing, They think they have done me no injury,† (lines 9-10). The child then states that his parents are at church praising God, his Priest, and King, but believes that they are the ones who have put him and the other children working in chimneys in their misery. The tone of this poem is despair, misery, and isolation. The child feels as if his parents have abandoned him by sending him off to work in the chimneys and pretending that he is okay. He feels despair and misery not only because of his forced labor, but also because he feels as if God is the one to blame. He believes that it is God’s fault for all the pain and horror that the chimney sweeps had to go through. The child’s characterization does change throughout the poem. He tells the speaker that he was once a happy child who would smile along the snow. Howeve r, after his parents sold him into becoming a chimney sweeper he became depressed. â€Å"They clothed me in the clothes of death, And taught me to sing the notes of woe.† (7-8).
