(15 marks)
The essays do not require in text references or a list of references.

Part B Hands on
You are to go through the Hands on exercise 5A on page 187 of the textbook. You will need access to a networked computer with access to the PING, ARP and TRACEROUTE tool. For some of the activity if you have a restrictive firewall you will need to search for a looking glass type services and modify your report accordingly (Goolge looking glass tools). The exercise has a number of activities for you to perform but for the assignment we only need the output and discussion for the following activities. IF you are using non Windows machines the commands may be slightly different.
IPCONFIG: Finding your computer settings
PING: Finding other computers
ARP: Displaying Physical Address
TRACERT: Finding Routes through the Internet
Each of the activities listed include a number of deliverables that you will need to attach as part of your assignment submission. For the output of the commands use the screen capture capabilities. Under Windows use Cmd Alt Print Screen keys combinations to capture the current active window and then paste into word document. For Mac OS use Command-Shift-4, then space, and then click a window you want to capture

Part C: Report (10 pages for body of the report)
Management has identified that in order to provide employees with mobile access a more flexible networking environment needs to be created. Since the organisation uses a typical client server network design, management feels that it would be a simple and reasonably inexpensive process to add extra…

Assignment: Data Analysis and Hypothesis Testing
Please use Excel to do the exercises listed below. Create the Excel outputs into a single Excel file. Also, create a tab separately for each (sub). Clearly name each tab, for instance “Q1_a” or “Q2b”.
Please access the “Carrier Dome Data” do the following.
1. Basic Data Analysis (in the Excel tab, procedures and results should all be included and easily observable)
(a) Create Cross-tabulation table of the following, (Use Pivot table function)
– Gender(X1) vs. Year in School (X2) vs. Commute method (X5)
– Gender(X1) vs. Interest in Exercise (X8a)
(b) Find the Means and Standard deviations of the variables X8a, X8c, X8g, and X8l.
(c) Find the Correlations of X8a, X8c, X8g, and X8l.

2. Hypothesis Testing (in the Excel tab, the variables used, procedure of testing, and the results should all be included and clearly observable)
(a) Test the null hypothesis that the mean of X8c is same for men and women. Using the P value, can you reject H0 at a 95% level of confidence?
(b) Test the null hypothesis that the mean of X8l does not exceed the mean of X8g. Using the P value, can you reject H0 at a 95% level of confidence?
(c) Test the null hypothesis that the mean of X8l does not exceed the mean of X8g by more than 0.8. Using the P value, can you reject H0 at a 95% level of confidence?

3. Create Two New Hypothesis (on your own) and Test at the 95% level of confidence, using the given data. The hypothesis should be about gender difference. For example, see Question 2 (a).
(In the Excel tab, exact hypothesis, the variables used, and the results should all be included and clearly observable)
(a) Hypothesis #1: _______________________________________________
(b) Hypothesis #2: _______________________________________________

Task 1
Your task in this assignment is to design, implement, test and document the basis of a simple online employment service using HTML, CSS, PHP, Smarty, and SQLite.
Functionality
The goal of the assignment is to design, implement, test and document a simple database-backed Web application that models part of a simple online employment service. The application should allow employers to:
post descriptions of jobs they are offering
delete descriptions of jobs they are offering.
It should allow users to:
browse the jobs being offered
search for all jobs in a given industry
Each employer (an organisation) should have:
a unique id
a unique name
an industry (e.g., education, government, information technology, manufacturing, mining, retail)
a brief description.
Each job should have
a unique id
a reference to the organisation offering the job (there is a one-many relationship between organisations and jobs)
a title
a brief description
a location
an annual salary.
You may assume the initial set of employers is given. That is, the developer should initialise the set of employers when the database is created. The initial database must contain at least 2 employers and at least 4 jobs.
The application should have separate home pages for employers (employers.php) and for users (index.php). Each home page should have a header that clearly identifies the application and a footer that clearly identifies the developer and has a link to the documentation (described below).
The employers home page (employers.php) should display a list of employer names. An employer may then select its name which leads to a page with list of summaries of jobs offered by that employer and a form (or a link to a form) for adding a new job. Each job summary should lead to a complete description of that job. The employer may then delete that job.
After adding or updating a job, the employer should see the complete description of that job. After deleting a job, the employer should…

Relationships are all there is. Everything in the universe only exists because it is in relationship to everything else. Nothing exists in isolation. We have to stop pretending we are individuals who can go it alone.
—Margaret Wheatley, Turning to One Another: Simple Conversations to Restore Hope to the Future
The rise of social media and its power to instantaneously connect people to others is a testament to just how interconnected the world has become. Social media has become an important way to form and maintain relationships. Many use social media platforms, such as Facebook and Twitter, to keep in touch with family, friends, and colleagues. Businesses search for new ways to connect with current and future customers. But, how many have recognized the potential of social media as a powerful learning tool?
Forward-thinking educators have begun purposefully building online social networks of colleagues and experts in the field, known as PLNs. Rather than see social networks as an annoyance or way of wasting time, they have made them an invaluable means of personal and professional growth. Business professionals can benefit from following their lead. PLNs allow professionals and committed lifelong learners to build relationships with others from all over the world. With careful work and commitment to building and maintaining a PLN, the possibilities for connection are endless.
To prepare: Consider new ways in which you might use technology to foster new connections and seek information and advice.
Use the APA Course Paper Template to complete this assignment.
Write a 6 page paper describing your PLN. Your paper should include the following:
•Text you might include in a professional profile, which you could use on a social media site (like Twitter, or LinkedIn) to identify yourself and your interests for those who might be interested in following you or joining your PLN
•Annotated list of five people or groups in which you might find people to add to your…

ELE3105 – Computer controlled systems 5 Assignment 1 A temperature control system can be modelled by the following transfer function G(s), where represents a pure time delay in the system and . You are required to implement a digital PID controller to track the temperature setting without error. 1. Analytically find the open-loop system response c(t) to a unit step input and plot out this response. (30 marks) 2. Based on sampling theorem, determine a suitable sample interval T for the following parts of the assignment. (Hint: Use Bode plots of G(s) to determine the system’s cut-off frequency. At cut-off frequency the magnitude plot is about 3dB below the magnitude of the low frequency. The cut-off frequency can be considered as the highest frequency component. Choose as an integer for calculation convenience). (40 marks) 3. Derive the discrete-time system transfer function GHP(Z) from G(s). (Hint: , where , and keep T as a parameter until the final results are available). (30 marks) 4. Design a digital Proportional (P) controller to form a unit feedback control system, and optimise its parameter with respect to the performance criterion using the steepest descent minimisation process. Simulate this P controller system and plot its response. (Please provide the plots that show the initial and the final/optimal responses). (50 marks) 5. If the P controller is replaced by a PID controller, determine the PID controller’s parameters with respect to the performance criterion for a unit step input. (Hint: Applying the steepest descent optimisation method again. Please also provide the plots that show the initial and the final/optimal responses).
