I’m working on a civil engineering question and need support to help me learn.

Write a brief reflection (1 page ) on the Entrepreneurial Mindset Imperative.

Implement an instruction-level simulator for a single cycle MIPS processor in C++. The simulator supports a subset of the MIPS instruction set and can model the execution of each instruction.

Skeleton Code

The file “MIPS.cpp” contains a skeleton code for the assignment. You need to fill in the missing code. In this section, we provide descriptions for each of the components in the skeleton code.

Classes

   We have defined four C++ classes that each implement one of the four major blocks in a single cycle MIPS machine, namely RF (to implement the register file), ALU (to implement the ALU), INSMem (to implement instruction memory), and DataMem (to implement data memory).

Main Function

The main function defines a 32 bit program counter (PC) that is initialized to zero. The MIPS simulation routine is carried out within a while loop. In each iteration of the while loop, you will fetch one instruction from the instruction memory, and based on the instruction, make calls to the register file, ALU and data memory classes (in fact, you might need to make two calls to the register file class, once to read and a second time to write back). Finally you will update the PC so as to fetch the next instruction. When the halt instruction is fetched, you are to break out of the while loop and terminate the simulation.

What You Have to Submit

1. We      have provided skeleton code in the file MIPS.cpp. Finish the code.  

• A Makefile has been provided for you to compile the source code. 
• We are working on setting up a server for development as was requested.
• You can compile your design by typing “make” which would create the MIPS executable. Run the executable using “./MIPS” command.
• You are welcome to write your own Makefile to compile the code (for example, if you add new header files etc) but in this case you must include a “howto.txt” file explaining how to compile your submitted source code. 
• Code that does not compile will automatically be given a 0.
• You are free to use whatever development environment you want, but you must upload your code with a working makefile.
• We have provided “imem.txt” and “dmem.txt” files containing a sample code (loading two variables and adding them) and initialized data. These files must be in the same directory as the source code.
• We encourage you to write your own MIPS programs and check your design for different cases. 

In the piping system shown above, 60 degree F water flows from point 1 to the valve and exits to the atmosphere. Point 1 is 31 feet below the valve outlet. The vertical section of pipe from point 1 to the elbow is 30 feet while the horizontal section of pipe is 50 feet. All pipe has inner diameter 2″ and equivalent roughness of 0.0025 feet. The elbow has loss coefficient KL = 0.5 while for the valve KL = 4.2.

Use the equation (p/γ + v2/2g + z)2 = (p/γ + v2/2g + z)1 + hS – hL or an equivalent equation to find the required pressure at point 1 (in psi gage pressure) for 64 gallon per minute flow from point 1 to the valve outlet (1 ft3 = 7.48 gallons). You can assume the water speed at the valve exit is the same as the speed at point 1.

Your steps should include calculation of the flow Reynolds number, the pipe friction factor and the head losses (or pressure drops) due to pipe and fittings.

Many organizations still do not have dedicated information security staff, although that is rapidly changing. Depending on the size of an organization, there could be a single employee who is responsible for maintaining and enhancing the organization’s security posture. This would also include basic operations, security checks, and user education and training, among many other responsibilities. This is typical of small organizations that do not have the resources necessary to stand up a full team of information security professionals. Larger organizations are typically better equipped to establish and maintain a dedicated information security staff. As you will see throughout this module, security professionals are often not embedded within an organization’s IT department.

For your initial post, consider the benefits of having dedicated roles within a security team versus having individual employees who must be jacks of all trades when it comes to improving an organization’s information security posture. Should you reference any internal or external resource, remember to cite your sources appropriately.

In your initial post, address the following:

• What are the advantages and disadvantages of having a dedicated security team?
• Select a role that was noted in the module resources that is of interest to you. If you are aware of other information security roles that were not discussed in the module resources, be sure to find a reference and cite it within your post.
• Explain your selected role and how that role supports and enhances security posture within an organization.

In response to two of your peers, build on each original poster’s claims, and answer the following:

• Do you believe that each of your peers’ selected roles would be a better fit for a small organization or a large one? Why?

Competency

In this project, you will demonstrate your mastery of the following competency:

• Apply statistical techniques to address research problems

Scenario

You are a data analyst for a basketball team. You have found a large set of historical data, and are working to analyze and find patterns in the data set. The coach of the team and your management have requested that you use descriptive statistics and data visualization techniques to study distributions of key variables associated with the performance of different teams. Data-driven analytics will help the management make decisions to further improve your team’s performance. You will use the Python programming language to perform your statistical analysis. You will also need to present a report of your findings to the team’s management. Since the managers are not data analysts, you will need to interpret your findings and describe their practical implications. The managers will use your report to find areas where the team can improve its performance.

Note: This data set has been “cleaned” for the purposes of this assignment.

• 3-3 Discussion: Confidence Intervals and Hypothesis TestingDiscussion Topic
  
  Starts May 15, 2021 10:59 PM

  Use the link in the Jupyter Notebook activity to access your Python script. Once you have made your calculations, complete this discussion. The script will output answers to the questions given below. You must attach your Python script output as an HTML file and respond to the questions below.In this discussion, you will apply the statistical concepts and techniques covered in this week’s reading to calculate a confidence interval and perform hypothesis testing for a manufacturing process.The manufacturing process at a factory produces ball bearings that are sold to automotive manufacturers. The factory wants to estimate the average diameter of a ball bearing that is in demand to ensure that it is manufactured within the specifications. Suppose they plan to collect a sample of 50 ball bearings and measure their diameters to construct a 90% and 99% confidence interval for the average diameter of ball bearings produced from this manufacturing process.The sample of size 50 was generated using Python’s numpy module. This data set will be unique to you, and therefore your answers will be unique as well. Run Step 1 in the Python script to generate your unique sample data. Check to make sure your sample data is shown in your attachment.In your initial post, address the following items. Be sure to answer the questions about both confidence intervals and hypothesis testing.

  1. In the Python script, you calculated the sample data to construct a 90% and 99% confidence interval for the average diameter of ball bearings produced from this manufacturing process. These confidence intervals were created using the Normal distribution based on the assumption that the population standard deviation is known and the sample size is sufficiently large. Report these confidence intervals rounded to two decimal places. See Step 2 in the Python script.
  2. Interpret both confidence intervals. Make sure to be detailed and precise in your interpretation.

  It has been claimed from previous studies that the average diameter of ball bearings from this manufacturing process is 2.30 cm. Based on the sample of 50 that you collected, is there evidence to suggest that the average diameter is greater than 2.30 cm? Perform a hypothesis test for the population mean at alpha = 0.01.In your initial post, address the following items:

  1. Define the null and alternative hypothesis for this test in mathematical terms and in words.
  2. Report the level of significance.
  3. Include the test statistic and the P-value. See Step 3 in the Python script. (Note that Python methods return two tailed P-values. You must report the correct P-value based on the alternative hypothesis.)
  4. Provide your conclusion and interpretation of the results. Should the null hypothesis be rejected? Why or why not?

  In your follow-up posts to other students, review your peers’ calculations and provide some analysis and interpretation:

  1. How do their confidence intervals compare with yours?
  2. If the population standard deviation is unknown and the sample size is not sufficiently large, would you still use the Normal distribution to calculate these confidence intervals, or would you choose another distribution? If the latter, which distribution would you choose?

  Remember to attach your Python output and respond to all questions in your initial and follow-up posts. Be sure to clearly communicate your ideas using appropriate terminology. Finally, be sure to review the Discussion Rubric to understand how you will be graded on this assignment.
