How Human Computer Interactions Incorporated Into Computer...

2. Purpose The purpose of the authors is to introduce the capabilities of context-aware design and give an insight into how it can positively affect and benefit the user’s lifestyle. The authors inform the audience of the three types of context-aware computer systems and uses prototype examples to clearly explain them to an audience who would not be knowledgeable about this field. The article highlights how human-computer interactions incorporated into computer systems are continuously evolving to provide a more personal, efficient and user friendly experience. This has further extended onto systems that recognise contexts and situations allowing less user inputs and more about understanding and analysing the user’s preferences. 3. Key Information 3.1 Framework Context aware design is the concept of computer systems being attentive of the user’s setting or context. It will recognise engagement and interactions from the user and model the situations to accomplish a set task or purpose. The fundamental framework of context aware designs takes into consideration a user’s personal needs which may be affected by many factors such as habits, self-image, and issues of motivation. Thus, many questions are raised and answered in the planning process regarding the purpose, intended audience, inputs and outputs required etc. to design such technologies that are able to understand and interpret what the user’s goals are. The prototype examples exhibit endless possibilities andShow MoreRelatedThe Myth Of The Ant Queen By Steven Johnson1420 Words   |  6 Pages Technology has tremendously changed human social behavior, which has provided a convenient way for people to communicate and collaborate with each other.

Math150 College Algebra Ctu Phase 1 Db2 Free Essays

MATH150-1201A-01 Phase 1 DB2 Part 1 and Part 2-Primary Task Response January, 2012 Part 1 Confirmation of MyLabsPlus login I was able to login to MyLabsPlus with my username and password. Part 2 Primary Task Response 1. I went into the learning lab and in the mathematics section I chose the presentation titled â€Å"Basic Algebra Skills-Real numbers Algebraic Equations, Exponents Scientific Notation, Radicals Radical Exponents, and Polynomials†. We will write a custom essay sample on Math150 College Algebra Ctu Phase 1 Db2 or any similar topic only for you Order Now I chose this presentation because I felt I needed to remember algebraic equations, exponents and polynomials. I have not had algebra for many years so this presentation was a very good refresher. It reminded me about real numbers and algebraic expressions and square roots. It was good to be reminded about the steps you take in algebra to solve an equation such as: 1. Perform operations within the innermost parenthesis first and working outward. 2. Evaluate all exponential expressions. 3. Perform multiplications and divisions as they occur, working from left to right. 4. Perform additions and subtractions as they occur, working from left to right. Overall the presentation was a very good reminder. I am happy I watched this particular presentation. I definitely will benefit by visiting the learning lab math center because I have not had algebra in many years and I will need the extra help to learn. 2. I would explain to the programmers in my new job that a mathematical expression is a phrase or a sentence fragment with a variable that has to be simplified and has no relation symbol. And that a mathematical equation is a sentence that you solve and has a relation symbol and is a statement that two numbers or expressions are equal. A couple of mathematical examples of the difference between an expression and an equation is: 1. Mathematical expression – 1. z + 2 ? (7 – z) 2. A number is less than five. x 10. 2. Mathematical equation – 1. 6 =6 2. 15 = 2 + 13 A real life example of when someone would use a mathematical expression is when a car is going a certain mph speed and the driver wants to know how many miles he has traveled after so many hours. A real life example of when someone would use a mathematical equation would be to figure their profit or loss during months of business. 3. I would explain to the programmer that the expression means five x five x five = 125 and not 5 x 3. I would explain that 5 is the â€Å"base† and 3 is the â€Å"exponent† or â€Å"power†. I would show him/her how to calculate it on paper. A real life example where one would use exponents is when one would need to measure square feet, square kilometers or square inches. You might also use it if you need extremely tiny or extremely big quantity results. References Math League Press, (copyright, 1997-2006). Introduction to algebra.

Installing A Hard Drive Essay Example For Students

Installing A Hard Drive Essay Installing a IDE or EIDE hard drive on a Pentium computer To install a hard drive in your computer you must have a decent knowledge ofComputers and know what basic commands do. I wouldnt recommend a beginner trying to install a hard drive. These instructions are meant for intermediates or above. Before you start you should have already bought your hard drive. You will need a Phillips screw driver, your Windows CD, and the manual that came with your computer. Before you get ready to install your new hard drive. Unpack the drive you just bought and make sure the hard drive, cables, manual, and diskette are there. We will begin by removing the four screws that hold the computer cover to the frame of the computer. The easiest way to identify which screws to take out is to see which screws are covering the painted edge of the cover. Other screws, which you dont want to take out, hold the power supply which could harm the computer. Once the screws are taken out, the cover may still be h ard to slide out. Use both hands, on each side of the cover and pull it out. Now find the hard drive it should be in the second slot starting from the top. Remember the drive should be about 3 1/2 inches in width, 6 inches long, and an inch in height.Usually the hard drive is a silver and black color. After finding the drive, make sure you remove any static carried in your body by touching something metal before touching the insides of the computer. Now you will find two cables; these are ribbon cables that connect the drive to the computer. You will also find a power cable; it has four separate wires connected to plastic connectors on each end. To remove the cables, you just pull straight out. This shouldnt take a lot of pressure, but just be sure pull the cables by the plastic connectors and not by the wires. Remove both ends of the cables for we will be replacing them with new ones. Remember where you take these out, for you will be connecting the new cables in the same place. After you get the cables off, remove the mounting screws that hold the drive in place. You should find them in the front and along the sides of the hard drive. After you get the screws out the drive will slide out the front of the computer. If it is mounted on the side push it out the back. Now take the new hard drive and slide it in the way the old one came out, and screw in the same screws the old one used. Now, attach the ribbon cables that came with the new hard drive. The three cables you will be connecting are different sizes and will only go in one way, so you dont have to worry about which cable goes where. Now connect the cables to the motherboard (the big green card where everything connects to) they should go in the same place where you disconnected the old cables. Remember the cable will only connect one way, so you may have to turn the cable around to make sure it fits right. Now that youve connected these ribbon cables, you can connect the power cables. Remember that these are cables with four separate wires connected to a white plug. The white plug is shaped to fit in only one direction; but in any computer, the colored wires from each end should plug into the same way. Now after all the cables are connected you can put the cover back on the computer the same way you took it off; by sliding the cover on and screwing in the screws. .u08de8b1577adee25a116846006b03f1c , .u08de8b1577adee25a116846006b03f1c .postImageUrl , .u08de8b1577adee25a116846006b03f1c .centered-text-area { min-height: 80px; position: relative; } .u08de8b1577adee25a116846006b03f1c , .u08de8b1577adee25a116846006b03f1c:hover , .u08de8b1577adee25a116846006b03f1c:visited , .u08de8b1577adee25a116846006b03f1c:active { border:0!important; } .u08de8b1577adee25a116846006b03f1c .clearfix:after { content: ""; display: table; clear: both; } .u08de8b1577adee25a116846006b03f1c { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u08de8b1577adee25a116846006b03f1c:active , .u08de8b1577adee25a116846006b03f1c:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u08de8b1577adee25a116846006b03f1c .centered-text-area { width: 100%; position: relative ; } .u08de8b1577adee25a116846006b03f1c .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u08de8b1577adee25a116846006b03f1c .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u08de8b1577adee25a116846006b03f1c .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u08de8b1577adee25a116846006b03f1c:hover .ctaButton { background-color: #34495E!important; } .u08de8b1577adee25a116846006b03f1c .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u08de8b1577adee25a116846006b03f1c .u08de8b1577adee25a116846006b03f1c-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u08de8b1577adee25a116846006b03f1c:after { content: ""; display: block; clear: both; } READ: AIDS (2495 words) Essay You can turn on the computer now.
