...How to Remote Install CentOS 6 via VNC For many reasons sometimes it is necessary to reinstall a linux on a server that is hosted in a remote location such as a Data center. You might want to install a new version of the Distribution, change the distribution, or you might need to re-partition you hard drive to be able to use LVM for example. You have three options here: 1 - Go physically to the Datacenter 2 - Pay a datacenter guy to reinstall that for you… :( 3 - Install it Remotely using VNC I chose the 3rd one since it seems to be the most convenient one. :-) What do we need? Network configuration of out server: IP Address, Gateway and DNS If you have all those 3 informations you are good to go! 1 - Download bootstrap files (Kernel and ramdisk image). # cd /boot # mkdir centos6 # cd centos6 # wget http://mirror.centos.org/centos/6/os/x86_64/isolinux/vmlinuz # wget http://mirror.centos.org/centos/6/os/x86_64/isolinux/initrd.img Add an entry to the Grub Loader # vi /boot/grub/menu.lst ## Add the following lines to the end of the file and count how many lines starts with tittle: title CentOS 6 VNC Installation root (hd0,0) kernel /centos6/vmlinuz vnc vncpassword=houseoflinux headless ip=10.0.0.10 netmask=255.255.255.0 gateway=10.0.0.1 dns=10.0.0.5 ksdevice=eth0 method=http://mirror.centos.org/centos/6/os/x86_64/ lang=en_US keymap=us initrd /centos6/initrd.img In my case with I had total 3 entries because I am updating...

...SURFACE SANITATION VERIFICATION PURPOSE: The primary purpose of this information paper is to provide guidance on the use and implementation of the Charm PocketSwab( for surface sanitation verification in commissaries located throughout EUCOM. BACKGROUND: ATP (adenosine triphosphate) bioluminescence has been used in the food industry for over 10 years to quickly assess and monitor microbial contamination on surfaces. ATP is an excellent means of identifying “hot spots” or areas with organic material that could possibly support and accelerate microbial growth. The technology of ATP bioluminescence for hygiene monitoring has become increasingly useful because of it real-time capabilities, ease of use and affordability. It cannot replace microbiological testing but it is easier, faster and the results indicate cleanliness, (defined as the absence of organic material), rather than counting colony forming units of microorganisms. SCIENTIFIC PRINCIPLE: It is important to understand the basic principles of ATP bioluminescence. ATP is a molecule that is essential and common to all plant, animal and microbial cells. This compound combines and reacts with an enzyme (luciferase) resulting in the release of light. The light emitted is measured by using the Charm LUM-T. This output of light is proportional to the amount of ATP present on a given surface. The measurement of biological contamination is approximated by determining the amount of ATP contained within or on the material...

...Specialist Mathematic Bezier Curve Investigation Introduction A Bézier curve is a parametric curve used in computer graphics. Bézier curves are used to model smooth curves in, for example, animation. Bézier curves were widely publicised in 1962 by the French engineer Pierre Bézier who used them to design car bodies. Paul de Casteljau first developed the curves in 1959. In the following investigation you will, individually, develop the algebra of Bézier curves and use them to design an object using Bezier Curves. Task 1 Aim Method * Linear Bézier curves Given points P0 and P1, a linear Bézier curve is a straight line between those two points. The curve is given by B(t) where B(t) represents the moving point between two points P0 and P1, and . Fig 1 Fig 1 Application * Quadratic Bézier curves A quadratic Bézier curve is the path traced by the function B(t), given points P0, P1, and P2. It departs from P0 in the direction of P1, then bends to arrive at P2 in the direction from P1. Fig 2 Fig 2 Consider Fig 2. From Fig 2 above use the points Q0 and Q1 as shown and the linear model from Fig 1 to show that the Bezier curve is defined as - and is therefore a quadratic Bezier curve. (2 degree equation) Task 1 continued * Cubic Bézier curves * Four points P0, P1, P2 and P3 in the plane or in three-dimensional space define a cubic Bézier curve. * The curve starts at P0 going toward P1 and arrives at P3 coming from the direction of P2. Usually, it will not pass...

...are left to you the student. Also you might need to add more detailed explanations or justifications on the actual similar problems on your exam. I will keep updating these solutions with better corrected/improved versions. Problem 1(a) - Fall 2008 Find parametric equations for the line L which contains A(1, 2, 3) and B(4, 6, 5). Solution: To get the parametric equations of L you need a point through which the line passes and a vector parallel to the line. −→ Take the point to be A and the vector to be the AB. The vector equation of L is −→ −→ r(t) = OA + t AB = 1, 2, 3 + t 3, 4, 2 = 1 + 3t, 2 + 4t, 3 + 2t , where O is the origin. The parametric equations are: x = 1 + 3t y = 2 + 4t, z = 3 + 2t t ∈ R. Problem 1(b) - Fall 2008 Find parametric equations for the line L of intersection of the planes x − 2y + z = 10 and 2x + y − z = 0. Solution: The vector part v of the line L of intersection is orthogonal to the normal vectors 1, −2, 1 and 2, 1, −1 . Hence v can be taken to be: i j k v = 1, −2, 1 × 2, 1, −1 = 1 −2 1 = 1i + 3j + 5k. 2 1 −1 Choose P ∈ L so the z-coordinate of P is zero. Setting z = 0, we obtain: x − 2y = 10 2x + y = 0. Solving, we find that x = 2 and y = −4. Hence, P = 2, −4, 0 lies on the line L. The parametric equations are: x =2+t y = −4 + 3t z = 0 + 5t = 5t. Problem 2(a) - Fall 2008 Find an equation of the plane which contains the points P(−1, 0, 1), Q(1, −2, 1) and R(2, 0, −1). Solution: Method 1 −→ −→ Consider the vectors...

Provide an example of each one that might be appropriate for your current or previous place of employment Similarities o A Z test and a t-test are each a type parametric tests. o Parametric tests are resultant data from the given ranges which have given the consumers to choose from intervals, such as 1-5. o Parametric tests such as the Z test and t test are used to “conclude if there is a statistical significance among the sample distribution average and a parameter (Cooper, D. & Schindler, P., 2011). o A Z test and a t-test could be opted as one sample test. One sample tests are opted when one sample is derived from a populace and a hypothesis “from the specified population” (Cooper, D. & Schindler, P., 2011), is tested o A Z test and a t-test could be used as a two sample test with each of its sample being independent. o The Z test and t tests are matching while the sampling size is more than 120. · Differences o The Z test and t test differ when the sample size is lower than 120. o The t test is suitable for minute sample sizes. o The Z test is suitable for huge or minute sample sizes. o A t test can be opted as a two sample test by pairing the samples. o A t test has more tail area, means most results that are lesser and greater than the central are rejected. It implies a t test would give a improved sample average since most results which diverge away from the mean...

Knowing how to research specific problems truned out to be crucial when it came to solve a specific problem, which opened my eyes as to the complication involved in it. There are two specific test used in this particular simulation which are Anova and Non-parametric. “Anova is defined as a statistical method for making simultaneous comparisons between two or more means; a statistical method that yields values that can be tested to determine whether a significant relation exists between variables.” (dictionary.com) “A non parametric test is a branch of statistics that are applied when populations are not normal or they are severely skewed data.” There were three lessons learned during this simulation which were how to monitor a situation. The importance to measuring the accumulated data and how to provide a reliable solution to the problem. It is important that we learn how to apply things that we learn in everyday life as well as the workplace. Using an appropriate test can help us whenever it is time to make a decision in business, which is one other thing learn while going over the simulation. This helps at the time of determining how to correct a stiuation in the workplace.

Working for a company that requires that we learn how comfortable our users are with their technology it is very important to use ordinal data for informative decision making. In our data sets there is a large majority of information that does not come in with a normal distribution. This is where it comes into play that a parametric test can aid due to the ability to examine information without normal distribution. One of the largest lessons in terms of these concepts is the data size that it takes to utilize these tests. Unfortunately as with any questionnaire my department usually gets only a small amount back. When working with parametric testing a small sample size would only go to hurt the result of the testing. When working with these tests it is possible to extrapolate the data and generalize for the mass amount. Unfortunately when working with parametric data it is not beneficial to use smaller data sets due to the fact that the results cannot reach normalcy. Working with this information, I feel that it is more possible for our department to better utilize the limited data sets that we receive and better inform our department director....

...ANOVA and Parametric tests Looking at the concepts in the book it is interesting with regard to placing them into the work world. The most recent concepts were ANOVA and nonparametric tests. ANOVA, also known as analysis of variance is a concept that allows you to “compare more than two means simultaneously and how to trace sources of variation to potential explanatory factors”. One of the biggest take aways from this concept is that the ANOVA tests can take on many factors or “treatments. This can be very beneficial when dealing with many factors. Although this does not mean that it is the norm to have many factors. Most researchers focus on a limited amount of factors. Another big lesson is with nonparametric tests.
