Zone0: Junkbot's Classwork

This is a feed where I can put all my classwork in electronic form, as opposed to a book. I hope to type up the stuff pre-sandbox on here.

Weak Points
 
NO sidebar plz... :)
I think that our Innovate with technology page was sufficient but didn't clearly meet the criteria. Admittedly. navigation was pretty bad. Company blog could have had more detail.
 
Strong Points
 
Professional = good. The headings could've been better... quite aesthetic.
 
Improvements
 
Navigation++
Don't leave it to the last minute.
FOLLOW the criteria.

Making Decisions

Explain how a dollar value could be determined for each of the tangible benefits list above.
  • Increased Sales
    • An increase in sales would increase profits. If sales were increased in certain products then profit would increase. This provides more income and possibly more money to
  • Cost Reductions
  • Increased Efficiency
  • Increased Profit on Sales
  • More effective use of staff time
  • System Development Lifecycle

    System requirements should address aspects of all the components of an information system, including participants, data/information, information technology and also information processes. Why do you think this is necessary? Discuss.

    Storing && Retrieving

    Reasons for S&R
    Example in manual system
    Example in computer-based system
    1. To allow the other processes to take place
    (a) Sorting elements using insertion sort, through the process of moving files in a filing cabinet (Organising)
    Storing elements in a database make it easier to sort (Organising)
     (b) You can't search for a number in a telephone directory if the data inside the directory wasn't stored in a book-like format. (Analysing)
    Storing data in a spreadsheet gives the option of displaying the data in a graph or chart. (Analysing)
     (c) You need a medium on which to change the data in a telephone book. You have to store the results somewhere otherwise they would be meaningless.
    Caching data can speed up processing by calculating required information ONCE. (Processing)
    2. To allow for a temporary halt in the system
    Moving an office with paper files would be easy if the paper was stored in a (filing) cabinet as you only have to move the cabinet and not each individual file.
    Storing data in non-volatile memory allows data to be stored and retrieved even when the power is turned off. Eg HDD, CD, USB etc.
    3. Backup and recovery
    Storing copies of receipts and forms (eg Carbon Copy) in an area separate from where the master copy is kept may give a backup in case of fire.
    Backing up a portion of files on a computer is vital in making sure any important files with have a version to revert to in the event of an accident. Eg back-up hard drive.

    Video is a combination of Audio and Images.

    MuseScore

    posted Jun 9, 2010, 4:46 AM by Unknown user   [ updated Jun 9, 2010, 5:17 AM ]

    See attached files. helloworld.mid is my composition and italianoverture is a demo.
     
    Data in italianoverture.mid is displayed in MuseScore as a series of notes on a stave. These notes represent different pitches (wavelengths) and durations (time). However, MIDI uses a series of numbers to encode different notes, each with its own unique pitch and duration.
     
    Processes suited:
    • Transmitting and Recieving as it is a universally accepted file type
    • Storing and Retrieving as the data is already in a numerical form
    • Displaying, eg MuseScore where these numerics can be converted into musical scripts
    • Processing as it is easy to modify the data in a program such as MuseScore

    Organising

    Organising Methods and Their Unique Uses

    Bitmap

    Original Image

    Inverted Colours

    The number of colours in the image is 255, thus any RGB value x in the original image is now 255 - x in the inverted image.
     
    Hue +180

    When the hue of an image is changed, the primary colours are rotated. This means that all R values move to become G values, B to R and G to R. (or similar). There are shades between these distinct swaps.
     
    Saturation -100

    The RGB value of each of the pixels average out to its surrounding pixels' corresponding RGB value slowly through the amount specified.
     
    Vibrance -100

    Makes the RGB values more distinct, heading towards either the upper or lower end. Eg 128<= heads towards 255 whereas >128 heads towards 0.
     
    Curves Input:13 Outpu:52

    Not sure :|.

    Vectors

    • This is an image format that stores images as mathematical representations of geometrical parts of the imae. Eg storing a line using general form.
    • You can edit shapes without losing quality (Bezier Curve)
    • Preservation of data
    What is the purpose of the following methods of organising images?
