Ethics Presentation

NSPE Code of Ethics for Engineers - link

National Society of Professional Engineers

• This is one of the documents used for interpreting ethical dilemmas submitted by engineers, public officials, and members of the public. 
• Use this code to analyze your / engineering ethics case study.  Consider the possible ethics violations, then argue the innocence or guilt of the engineers involved.  What principles were violated? What steps were taken to prevent future failures?

NSPE Board of Ethical Review - link 

Assignment:

• Imagine you are on the NSPE Board of Ethical Review.  Read through a few previously addressed Ethics cases:

• http://www.nspe.org/sites/default/files/resources/pdfs/Ethics/EthicsReferenceGuide.pdf

specific cases:
Fill in the short form for access to cases.
http://www.nspe.org/resources/ethics/ethics-resources/board-of-ethical-review-cases#2014

then-

• Choose a recalled product, or engineering disaster.
• Ethics notes: http://intro1201.blogspot.com/2015/04/engineering-ethics.html

Space program accidents: 

http://intro1201.blogspot.com/2015/11/manned-space-program-accidents.html

As a group, or individually, create a 5 minute long video outlining your chosen engineering ethics case.

 Engineering Case Study Presentation:  

1. Cite the disaster or product recall that you decided to investigate.

2. Briefly list (in bullet form) the facts about the incident.


3. List the ethical issues involved, and prioritize these issues from most critical to least critical.


4. How was the case resolved in real life?  (ie, who lost their job, how much $ were the victims paid, what new regulations were imposed, etc.) Do you agree with outcome on your case?  Should more have been done? less?  Support your answer by citing relevant sections in the Code of Ethics, and through using background info on the resolution of other similar cases.


5. Discuss this case from the perspective of :

a.) The public

b) The company managers

c) The company employees

 6. After this incident was resolved, if you were an authority figure for the company, what steps would you take to ensure future ethics violations would not occur?  


7.  Think about what ethical issues might come up in your chosen field of work.  How do you plan on addressing these issues?  If you find yourself in a dangerous working environment or involved with a project that is taking a bad turn - who can you go to for help?

8. Create a Fault or Event tree of the event.  What risk control measures were taken?  What should have been done?

Example presentation:

Note the clear concise slides with large font.  Do not paste your entire report onto your slides, just outline the main points!

Use Large clear images. 
A slide with only one clear image is better than a cluttered slide with a bunch of text and multiple images.  The audience's attention should be on the presenter, not distracted by trying to read and figure out cluttered slides.

Presenters knew the material well enough that they were able to discuss the below images without the need to read text off of slides, so they did not need to clutter the below slides with explanatory text. 

There is probably a little too much text on these two slides, but they still contain good information.

What is the difference between plagiarism and research?
Research work has references - and uses more than one reference!  A common practice is to reserve the last slide for references, "thank you" to contributing groups and people, acknowledgement of companies involved, etc. 

Excel VBA

Excel VBA:

  Create your own functions and Basic codes in Excel!

VBA - Visual Basic for Applications
Macros - short programs or sets of recorded keystrokes

Two ways to create a Macro in Excel:
1. Record a set of keystrokes
2. write a VBA subprogram


Excercise #1: Record a set of keystrokes
Open up the circuits Macro-Lab from D2L:

• MeyersMacroEx.xlsm
• Enable editing
• Enable Macros

Click on the "Developer" tab.
If the developer tab is not showing up in your ribbon:
(you might have a different version of excel, but it will be something similar to -
File→Options→Advanced→Customize Ribbon→Main Tabs

Have a look around in the Developer tab
 - hold your curser over an icon to see what it does.

Create a Macro program by recording your keystrokes:

Set up your cell referencing:

• Absolute referencing - if your calculations come from a stationary cell like "A3" etc. that will never change.
• Relative referencing - if your calculations will be made relative to a given cell - example, "in the cell to the right of the currently selected cell"

We are going to use relative referencing.  Select the yellow cell as the place everything else will be referenced from:

Click on the Developer tab
Click on the yellow cell
Click on "Use Relative References"

Now, select "Record Macro"
Name your Macro "Series", set up a shortcut key of "S", add description of what your program will do "Macro to calculate voltage drops and current for 3 resistors connected in series"

Once you hit "OK" the Macro will start recording everything that you do.
Fill in the first table just like you did for the lab.  When you are done, hit "Stop Recording"

Note: 
Do not use dollar signs in your macro ($F$8) etc. as this will not allow you to use relative referencing for new tables.

Enter each new equation by hand rather than copy/paste.

"Stop Recording" when you are done filling in your table.

Once you have created your Series Macro, try it out on the second table:
Click on the "Series Macro Starting Cell:
Enter your shortcut key "Cntr + s"
Did it fill in the table in for you?

You can also run your Macro from the ribbon:
Select your starting reference cell
hit "Macros"
Find the Macros you just made
hit "run" to run your program
hit "Edit" to view the VBA code

Click on "Edit" and have a look at the code that was generated from how you filled in your table:

Sub Series()
'
' Series Macro
' Macro to calculate voltage drops and current for 3 resistors in series.
'
' Keyboard Shortcut: Ctrl+s
'
'lines that start with ' are comment lines.  This is not part of the code, it just explains to other users what the program does.

    ActiveCell.Offset(4, 4).Range("A1").Select
    ActiveCell.FormulaR1C1 = "=RC[-3]+RC[-2]+RC[-1]"

The first thing I did was to calculate the total resistance. 

From the starting cell, I moved down 4, and over 4 (4,4)
Then I entered an equation in the new active cell → Row one Column one (R1C1)
I grabbed the cell in the same Row, 3 columns to the left (RC[-3]) added it to RC[-2] and so on

    ActiveCell.Offset(-1, 0).Range("A1").Select
    ActiveCell.FormulaR1C1 = "=R[-1]C/R[1]C"

Next I moved up one row, stayed in the same column, ActiveCell.Offset(-1, 0)  and calculated the current from the cells above and below where the new active cell is "=R[-1]C/R[1]C:

Read through the rest of your code, do you recognize what each line is doing?

    ActiveCell.Offset(0, -1).Range("A1").Select
    ActiveCell.FormulaR1C1 = "=RC[1]"
    ActiveCell.Offset(0, -1).Range("A1").Select
    ActiveCell.FormulaR1C1 = "=RC[1]"
    ActiveCell.Offset(0, -1).Range("A1").Select
    ActiveCell.FormulaR1C1 = "=RC[1]"
    ActiveCell.Offset(-1, 0).Range("A1").Select
    ActiveCell.FormulaR1C1 = "=R[1]C*R[2]C"
    ActiveCell.Offset(0, 1).Range("A1").Select
    ActiveCell.FormulaR1C1 = "=R[1]C*R[2]C"
    ActiveCell.Offset(0, 1).Range("A1").Select
    ActiveCell.FormulaR1C1 = "=R[1]C*R[2]C"
    ActiveCell.Offset(4, -3).Range("A1").Select
    Application.Run "'circuits Macro-Lab.xlsx'!Series"
    ActiveCell.Offset(0, 10).Range("A1").Select
    ActiveWindow.Zoom = 115
    ActiveWindow.Zoom = 130
    ActiveWindow.Zoom = 145
    ActiveWindow.Zoom = 160
    ActiveWindow.SmallScroll Down:=-6
    ActiveCell.Offset(-6, -10).Range("A1").Select
    Application.Goto Reference:="Series"
End Sub

Create Macros for the Parallel and Combined tables just like you created it for the series tables.

Save your file as a Macros enabled workbook, and email me your file:
File→ Save As→ Save as Type→ Excel Macro-Enabled workbook *.xlsm

Recall: Two ways to create a Macro in Excel:
1. Record a set of keystrokes
2. write a VBA subprogram

Let's try out #2.

Start in the Hello Sheet and look around.  Click on the buttons to see what they do!

Create a new Sheet to make your own "Hello" program

+ to add a sheet
Double click on the sheet to rename it. 


Create a "Hello" Button:
Insert → Button

There are two types of buttons:

• Form Control - simpler, easier to use, but limited
• ActiveX Controls - Allows you to control more properties

Choose an "ActiveX" button so that you can change the color etc.

 Click and drag on the screen to place the button.

Select "Design Mode:

 Select, then right click your button to:

• Edit the text: Command Button Object - Edit
• Change the "properties" (font color, background color color),
• View your code

Right click and "View Code" or Double click on the button to view code

Type in some code to make the button do something when you click on it, like write "Hello World" into cell D12

Range("D12").Value = "Hello world!"
Range("D13").Value = "How are you today?"

Press F5 key to run your code, or click the green arrow.

Close your editor window, and return to your excel sheet.
Erase the text your program created, click on the button, test it to make sure it is working ok.

Add some more buttons:

Do you remember how to format the font, text, and color of your buttons?
Design mode →right click!

Add some more code to each of your new buttons:

If OptionButton1.Value = True Then Range("D23").Value = "I'm happy to hear you are doing well!"

or

If OptionButton2.Value = True Then  Range("D23").Value = "So sorry to hear you are not doing well."

Note:  You can change your font style for each cell from the home tab

Save your work as a macro enabled worksheet:

Look through the programs in the other sheets:

Edit the below Meyer's personality test to write out your star trek character!
see:
http://randommization.com/2013/12/10/myers-briggs-personality-type-matched-star-wars-star-trek-characters/

Go to the Meyer's sheet
Open up the code by click on "Macros" in the Developer ribbon
"Step into" any of the Macros
Click through the different modules until you find the personality type program

Read through the personality code, can you figure out what it is doing?

Can you edit this program to also display Star Trek Characters?

Is there a better way to create the above program?
Use the Meyer's program to record each team member's personality type.  Use personality types to help decide what tasks to assign each team member.

Kolb Learning Styles - see Kolb sheet

see:
http://intro1201.blogspot.com/2015/03/jung-meyers-typology-perrys-scheme.html

Look through the Kolb code.
Try out the Kolb Learning styles test.
Record the learning style of everyone in your group.

Code::Blocks

Download it for free here:

http://www.codeblocks.org/downloads/26

Open it, choose:

Create a new project → Console application

Open it, choose C++

At School - make a new file in C: to temporarily save your work in:

[...]
Computer - local disk C: - make new folder - codeblocksfiles

Type in a project title (project filename and resulting filename will fill in automatically)

At home: A folder on your desktop might work better

Use all of the defaults for this

Open up Sources→main.cpp

The classic "Hello World" program should already be here for you to do a test build and run with.
First build it by clicking on the yellow gear, then run it by clicking on the green arrow.

Did you get an error?  read the error at the bottom of the screen
It can't find the compiler?
Settings→compiler→Global compiler settings→Toolchain executable→ "Auto Detect" compiler's installation directory

just google whatever errors you find, make sure all of the paths are set up correctly.

Once it is set up correctly, it will compile and you will get a black screen with "Hello World" written on it.

Hello World!

For a description of what all of the lines in your first "hello world" code are doing, read this:
http://www.cplusplus.com/doc/tutorial/program_structure/

The above website is a great resource to give you some basic preliminary tutorials if you are interested in teaching yourself.

Let's add a little more to your program:
~~~~~~~~~~~~~~~~~~~
// operator order
#include <iostream>
using namespace std;

int main ()
{
    cout<<"Hello World!";

  int a, b;         // this declares "a" and "b" as being integers that initially have no assigned value
  a = 8;           // here we assign a the value of 8
  b = 2;            // now b is assigned a value of 2
  a = b;            // just a demo of the importance of order, a is now equal to 2,
  b = 15;            // now a still equals 2, but b has changed to 15.

  cout << "\n a:"<< a;          //cout writes information out to the screen
  cout << "\n b:"<< b<<"\n\n";
}

~~~~~~~~~~~~~~~~~~~~~~~~~~

cout<< "for input and output, see";
http://www.cplusplus.com/doc/tutorial/basic_io/

What if there is an error in your code?

Change "a" to "A" and see what happens when you try to build it:

The red square show you where the error is, and your build messages tell you what the problem is.  If you do not understand the error message, just gooogle it!  In this case, "A" has not been declared - in other words, we did not tell the computer if "A" will store a letter or a number, and if a number what kind of a number - how many bits should it reserve for this information?  If I change "a" to "A" above, I will fix the error:

You can call your variables whatever you want, just be consistent!
Now, try this - change the integer "2" to something with a decimal like "2.315" and see what happens:

Note that the output is still the integer "2" even though it is typed into the program as 2.315.  If we change the variable b from being an integer to holding more information we will have to declare it as something different than an integer, like float:

A list of different types of variables can be found here:
http://www.cplusplus.com/doc/tutorial/variables/

for, if, while...

http://www.cplusplus.com/doc/tutorial/control/

Study this program, and see if you can figure out what it is doing:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
//Airplane.cpp : Program to demonstrate for statements.

#include "iostream"
int main(void)
{
   int count;
for(count=1; count<=500;count++)
std::cout<<"I will not throw paper airplanes in class.";

return 0;
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
for (initialization; condition; increase) statement;

The point of computer programs - to perform all of those monotonous repetitive tasks we would rather not deal with!

//bottles of beer song lyrics
#include "iostream"
using namespace std;

int main()
{
int n, c,count;
  cout << "Enter the number of beer bottles you want to start out with" <<"\n";
   cin >>n;

   c=n+1;

for(count=0; count<=n-1; count++)
{    c -= 1;
   cout<<c<<" bottles of beer on the wall "<<c<<" bottles of beer"<<"\n";
   cout<<"take one down, pass it around,"<<c-1<<" bottles of beer on the wall"<<"\n";
   }

return 0;
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
see: http://www.cplusplus.com/doc/tutorial/operators/


Class exercise #1:
Modify the below program to write out the Fibonacci series using a for loop:

Just replace "????" with what it needs to be!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
//Fibonacci series Program to demonstrate for statements.

#include "iostream"
using namespace std;

int main()
{
int n, a=0,b=1,c,count;
  cout << "Enter the number of terms of Fibonacci series you want" <<"\n";
   cin >>n;

cout<<"1"<<"\n";

for(count=0; count<=n; count++)
{    c = a + b;
         a = ????;
         b = ????;

cout<<c<<"\n";}

return 0;
}

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 

Class exercise #2:

 

 

Fix the equations in the below program so that it correctly calculates someone's age (slightly different equation if someone has already had their birthday, vs. if they have not had their birthday yet).  

 

Add one more if statement that writes "Happy Birthday!" if currentmonth = birthmonth

 

 



 

// Age Calc.cpp : Program to calculate someone's exact age.

 //

#include <iostream>

#include <conio.h>
#include <time.h>
using namespace std;

 int main()

 

 {

  int birthmonth,birthyear;
int currentmonth,currentyear;
int agey,agem;

cout << "\n\n\t\t\t Age Calculator\n\n";

cout <<"Enter Your Birth Year(Eg:1989):";
cin >>birthyear;
  cout<<"\n\nEnter Your Birth Month(Eg:7):";

 cin>>birthmonth;
  if(birthmonth > 12 || birthmonth < 1)
   return 1;

  time_t t = time(0); // get time now

struct tm * now = localtime( & t );
 currentmonth = (now->tm_mon + 1);
 currentyear = (now->tm_year + 1900);

  if(currentmonth>birthmonth)
{ agey=currentyear-birthyear;
 agem=currentmonth-birthmonth;}

  if(currentmonth<birthmonth)
{agey=currentyear-birthyear;
 agem=currentmonth-birthmonth;}

 

  cout<<"\n\n\t\tYour Age is "<<agey<<" Years And "<<agem<<" Months ";

 _getch();

  return 0;

 }

Example Codes:

The best way to learn how to program, is to study open source codes.

Can you figure out what each line is doing in the below codes? 
Just google terms you do not understand!

Create a simple code of your own -

Examples:
grade calculator - enter HW grades, have it add them up and average them
circuits: enter resistor values, calculate voltage drops for a series circuit
Friction:  Enter slip angle, calculate friction coefficient - can you find what library file you need to include for this one?
