Part 1: This includes an Excel spreadsheet that performs specific calculations.
The Insurance Institute for Highway Safety, IIHSLinks to an external site., states on their site that “Providing adequate yellow signal time is important and can reduce crashes. Studies have shown that increasing yellow timing to values associated with guidelines published by the Institute of Transportation Engineers can significantly decrease the frequency of red light violations and reduce the risk of total crashes, injury crashes and right-angle crashes (Bonneson & Zimmerman, 2004Links to an external site.; Retting & Greene, 1997Links to an external site.; Van Der Horst, 1988Links to an external site.; McGee et al., 2012Links to an external site.)._
You will design an Excel spreadsheet that calculates the allowable yellow light interval before changing to red and the red clearance interval based on the Virginia Beach Signal Timing Information. Links to an external site.
The equations that you will implement in your Excel spreadsheet calculator are available on slide 5 of the Signal Timing information.
Your Excel Spreadsheet should show the following:
Posted Speed Limit
Adjusted Speed limit
Intersection width
Vehicle Length
Yellow Change Interval
Red Clearance Interval
Total interval to come to a stop
You will create charts showing the change in the Yellow change interval, Red clearance Interval, and the total Change time for each posted speed used. You will discuss in Part 2 of your project your conclusion based on those results.
You can investigate in your Excel spreadsheet with different reaction times, deceleration rates, and vehicle length.
Part 2: This includes the development of a PowerPoint presentation showcasing the project enhancement as well as the Excel spreadsheet you designed.
You will design a PowerPoint presentation that details the added functionality of the traffic light system you designed as well as the results of your Excel spreadsheet calculations and comparison charts completed. This portion of the course project is worth 30% of the total project grade.
PowerPoint Presentation Requirements
No more than five (5) slides.
Must have a title slide.
Must have transitions of your choice between slides.
Must include an animation of bulleted points.

I chose to look at “Making Changes to the work of another Engineer”, Case No. 09-6. I chose this subject because it is something I deal with daily at work and wanted a better understanding of the issue so as to avoid ethical issues in the future.
The question presented in this Case was, “Was it unethical for Engineer A to makes minor changes to design documents prepared and revised by Engineer B without consulting?”, (NSoPE, 2010)
In this case the NSPE Board of Ethical Review did find that, “It was not ethical for Engineer A to make minor changes to design documents prepared and revised by Engineer B without conferring and gaining the approval of Engineer B.”, (NSoPE, 2010)
In my professional career, I am currently an Electromechanical Technician II and work in Engineering R&D I am responsible for cable and harness design and mechanical design work which includes documentation of the design in CAD and Altium (an electrical design program) as well as maintaining revision-controlled documents. In doing so I am answerable to my direct manager who is an Engineer as well as the Responsible Engineer on any given project, both within the Electrical and Mechanical Disciplines.
In doing my work as assigned, especially within a project, there have often been times when I have run into design conflicts with what I am trying to accomplish and what another is trying to accomplish with interacting parts in the design.
First, and I feel very strongly about this, it is not only unethical and dangerous but also rude to simply make changes to another person’s design without consulting them and presenting your findings and reaching a mutual agreement that the changes you are proposing to their design are justified and the best solution. There may be reasons they designed it that way that you do not understand.
Now, in the case that the other individual does not have the time to rework his design, they are on to another part of the project, etc., to meet a solution that you both mutually agreed upon we handle it with revision control. If the other individual designed to REV AB I would then revise it to REV AC and in the title block we capture that I am the author of the change, the responsible Engineer reviews and approves my changes and they are indicated on the title block as the approver and the dates are shown and all changes and agreements to the change are further documented, in our case we use JIRA as change control to document this work.
If there were an issue that ever arose from the design of that part, it is then clearly documented who is responsible for the design and any changes made to the design.
The bottom line however is that it is just common courtesy, when possible, to discuss any changes to another person’s work and just good practice in developing good working relationships. Respect reciprocates respect.

I looked up the article “Making Changes to the Work of Another Engineer” this article talk about 2 Professional Engineers working on the same project together. The problem comes when one engineer tries to revise another engineer’s work. Section II.2.b of the NSPE code of ethics says that you cannot sign for any documents that you haven’t prepared, or have prepared under their direct supervision and control. In this way, that engineer was wrong to revise the other engineers’ work. This would have been ok if one engineer was the lead of the project and the other engineer was taking direction from him to complete the work, but in this case, they were seen as equals and that makes the signature questionable because even if they have the same background and are both competent to do the work the engineer that signed off on the other one work would not have been fully involved with that aspect of the project and could easily overlook something.

The topic I chose was, “Why Can’t This Soap Dispenser Identify Dark Skin?” The subject is how sensors within things like soap dispensers, paper towel rollers, etc. can’t see a person’s light reflective characteristics because their darker skin absorbs more light than a fairer person. I do not believe there are any ethics violations presented in this article. However, I got the impression that the author of this article is trying to grasp straws and loosely imply that this is somehow a racist issue or can be viewed as such. This is in my opinion a technology oversight when companies are developing products.

The Cosine Rule is used in triangles where one is trying to relate all three sides to one angle. If you need to find the length of a side, you need to know the other two sides and the opposite angle.
Formula
a2 = b2 + c2 – 2bc cos(A)
Side a is the one you are trying to find. Sides b and c are the other two sides, and angle A is the angle opposite side a
Example
Christiano Ronaldo is taking a shot at a standard 24 foot goal post. He is 32 feet away from one goal post and 45 feet from the other. Through what angle can a goal be made?
Explanation : cosine rule
We will aply cosine tule to this problem because we know the three lengths.
24ft ^2 = 32ft ^2 + 45ft ^2 – 2(32ft)(45ft) cos θ θ = cos−1 (24 ft ^2 – 32 ft^2 – 45ft^2) / -2(32ft)(45ft)
θ = 30.8312430
CR7 would have to shoot the ball around 31 degrees to score a goal.

I will be using the Law of cosine
a2=b2+c2-2bc*cos(deg)
Example: would be if a car in the dessert was traveling 4.3m one way then turn at 30 degrees and went to 7.2m another direction.
If side b = 4.3m at an angle of 30 degrees and another side c =7.2m we use the law of cosine as such.
a2=4.32+7.22-2(4.3)(7.2)*cos(30)
a2=18.49+51.84-53.6243
a2=16.7057
once your answer you can now solve for side a. to do that you would need to take the square root of it.
a2=16.7057 will now be
which should give us 4.08726
round to 4.1m
I think this would be how cell phones are tracked too.
Rectangular vs. Polar Form—An Engineering Point of View
To work with complex numbers, it helps to have a standard mathematical notation. There are two basic forms of complex number notation:
· Polar form
· Rectangular form
Polar form is where a complex number is denoted by the length (also known as the magnitude) and the angle. In rectangular form, the complex number is denoted by its respective horizontal and vertical components.

I chose the topic of rethinking electronic education. Learning electronics through projects is a great idea for getting students to learn. Being enrolled in school and this particular class gives me a sense of wanting to understand what electronics is all about. Learning circuitry and electronics and getting hands-on experience is a great help. working for a pharmaceutical all different types of electronics to make sure everything is together and is checked properly. Using not only the human but sensors switches cameras lasers all help with getting the product out. And having project learning gets you prepared and a solid foundation of what to expect when out in the field.

For this week’s discussion topic, I chose the ‘Condition Monitoring for Industrial Manufacturing’. I currently work at a chemical facility that makes specialty plastics for a variety of consumer applications. My role is to inspect the fixed equipment and piping, and condition monitoring is a big part of my day-to-day tasks. However, I do not deal with rotating equipment, and the ni.com solution was all about it. I can see it being used in our manufacturing section of the plant (non-pressure systems) where we typically have product flow, internal breakage and other types of issues that would benefit from remote monitoring. Reaction time to these problems can be reduced from hours or days to a much shorter time based instead of product flow percentage loss or some similar metric.
