I. DATA ANALYSIS:
Introduction to Data Analysis
Why do we analyze data?
Make sense of data we have collected
Basic steps in preliminary data analysis
Introduction to Data Analysis
Editing of data
Impose minimal quality standards on the raw data
Field Edit -- preliminary edit, used to detect glaring omissions and inaccuracies (often involves respondent follow up)
The Martian: Hard or Soft Science Fiction?
A popular interest among science lovers today is an interest in Mars, possibly because we are becoming much closer to being able to send people there. One of the most popular, and most recent, works regarding Mars is The Martian, a novel by Andy Weir that later was adapted to film by Ridley Scott. The main story is that astronaut and botanist, Mark Watney, is abandoned on Mars by his crew after being struck by flying debris in a large sandstorm. There,…
1) What is a PCV? What does PCV stand for? What is another name for PCV? Describe the procedure for obtaining a PCV.
o PCV stands for packed cell volume.
o Another name for a PCV is hematocrit.
o A PCV is the measurement of the ratio of packed red cells in a known volume of whole blood sample.
o The procedure is to take blood from your patient and put it into a purple top tube, which has the anticoagulant EDTA in it.
• Next you need to fill 2 micro hematocrit tubes with the blood about ¾ a…
a) What is the main use of stepper motors?
In essence, stepper motors are applied in motion-control positioning system. For instance in 3D printers, disk drives, intelligent lighting, scanners, CNC machines, printers, camera lenses, plotters and slot machines.
b) What are the similarities and differences between a reluctance, a permanent magnet and hybrid stepper motors?
The three motors are similar in that, they all have power electronic control that comes with electronic…
My computer is an Apple MacBook Pro 13’. A MacBook is part of Apple’s computer family and was introduced in 2006. Every since then, technology has improved greatly and now a lot of the newer Macs are enhanced. For example, in 2013, Apple released “retina display” to their computer family to enhance the screen for consumers to use. The new retina display screens are way more bright and clear. I mainly use my MacBook for everything, from watching Netflix, to doing all different types of school…
is indeed a process, attempting to analyze it came with some hardships. A potentially infinite number of variables as well as difficulty finding data steered us in a new direction. Hard drives. Our group members have all had hard drive issues in the past, and we couldn’t help but notice how…
are designed with multi-core processors that capable of processing over 100 billion instructions per second. The addition of more memory has also increased the speed of todays’ computers. New hard drives, that have no moving parts, are being used, resulting in faster read and write times from and to the hard drive. (Information used to answer this question was referenced from the website,…
access to data frameworks. The scopes of potential digital evidence supports have grown exponentially, be it hard drives in personal computers and laptops or solid state memories in mobile devices such as smartphones and tablets, even while idleness times linger behind. This paper discusses four best sources of data that forensics experts hunger to get their hands on. They are log files, hard drives, mobiles devices, and social networking websites. Each of these sources has its own…
Since the beginning, IBM has been viewed as the backbone into the field of Information Technology. Leading the market in technology, it has provided services to different sectors ranging from mainframe computers to nanotechnology. This report aims to highlight IBM’s use of technology to manage through the challenges that were forced upon companies during the Global Financial Crisis (GFC) from 2007-2009. It explores how IBMs response to the GFC was mainly focused around the concept of ‘Smarter…
In the next picture you can see the RAM is placed in the slot. It is positioned in with small amount of force until the clips click into to place.
• In the next picture we installed in the hard drive which is positioned in vertical position, when you turn the computer on its side.
• The hard drive is then connected to the motherboard which is connected to all the wires.
• The power supply is then inserted inside the computer tower where we used the screws to screw it into…
