Robotics Activity Blog:
Summary:
For the past two weeks, we have been using a program called LabView on the computer. With this program, we are able to manually decide on how the Lego robot will move. We can program the robot to move in different powers, distances, and numbers of rotations.
Objective:
The objective of the lab this week was to compare the distance traveled using the LabView program and a ruler.
Measurements&Results:
Diameter of the wheel: 5.5cm or 0.055m
Circumference: 0.1728m

Comment: From the experiment, I learned that the program is capable of measuring extremely accurate numbers. I was very impressed by this program and as a future reference, I would like to use this program again.
Questions & Answers:
1. The wheel rotation (in degree and in number of turns). How are the degree that the wheel rotated related to the number of turns of the wheel?
A: It is proportional. Every  1 rotation is 360 degrees.
2. The time it took for the wheels to turn (in seconds and milliseconds). How are seconds related to milliseconds?
A: In every 1 second, there are 1000 milliseconds.
3. The distance the car moved. How is the distance related to the numbers of turns?
A: From our previous calculations, the circumference is the distance that the car moved per rotation. Which is 0.1728m.

Experience: I really enjoyed doing this lab because it was fun as well as educational in how technologically advanced we are becoming with these programs.

Germany’s Green Energy Policy Blog:

.          “Going Green” has been the new
trend these days. Everywhere we look, we would see different advertisements
telling us to “recycle” or “stay green” to promote renewable energies as well
as to cut down on the amount of pollution.
.          Every year, when all of the
countries gather up at the Earth Summit, both developed and developing
countries come together to become more  eco-friendly and to be more conservative.
However, the only country that has been successful out of these countries is
Germany.  It may seem very odd for such a
powerful and economically well developed country to be extremely passionate
about being environmental but from my research, I found out that it was due to
multiples of past events that have occurred.
.         Germany became extremely
environmental when the nuclear power plant in Japan (Fukushima Daiichi) exploded
last year after the tsunami hit its coast line. Due to the leakage of nuclear
radiation and the extreme confliction over what they should do with the waste,
Germany became enormously traumatized over the fact that the same thing may
happen to their own country as well. As a result, the German officials voted to
stop using nuclear power plants and transition to renewable energies. As a way
to stop using nuclear power plants, they decided to replace nuclear power
plants with wind turbine. Each turbine is about 130 meters tall and has three
61.5 meter blades attached to them; according to their research, each
revolution produces about 5 megawatts of electric power. In addition, German
Environment Minister, Nobert Rottgen, stated that he wants to decommission all
of its nuclear power plants by 2022 and obtain at least 80 percent of its
energy from renewable sources by 2050.
.          Although all of this
information about how Germany is going to be a success country with only
renewable energy sounds amazing, there are some negative things about this
project. First of all, Germany started off great. They were building turbines,
but so far they have only placed three turbines when in 8 years, there should
be hundreds of them. Secondly. Germany lost their lead in the transition to
greener sources of energy because of backlash, and environmental changes. In
addition, many critics have stated that this will cause explosions in prices of
electricity, power shortage, or missed environmental targets due to climate
changes.

 

.        From my point of view, I think
its wonderful that such big and strong country in the EU system is trying to
show other smaller and weaker countries that renewable energy is wonderful, but
if they somehow fail to become eco-friendly, then there will be no use. So as a
hope, I really wish that Germany will succeed and show the entire world that anyone
can become eco-friendly if they work together.

Lecture One: CDM Smith (September12, 2012)

Overall Story of our lecture:
On September 12, 2012, we were introduced to Guillermo J. Vicens.
He is a Senior Vice President from the company CDM Smith and came to our class to talk about how CDM Smith has many oppurtunities for people who are trying to major in Environmental Engineering.

motto: “listen.think.deliver”

What I learned from the lecture:
About Guillermo J. Vicens:
He is a CDM Smith Senior Vice President and a member of the firm’s Board of Directors and Executive Leadership Team. Also a Group President of the Consulting and Engineering Divisions(responsible for management oversight of nine technical service divisions)

Goals of the company:
– to provide all employees with a resource that would allow them to be active in mapping their career goals and aspiration
– to create a tool that managers and employees could use as the foundations of meaningful discussions around career development

About the CDM Smith Projects:
As of right now, there are five projects that CDM Smith is working on.
They can be categorized into five sections:
(Water, Environment, Transportation, Energy and Facilities)

Water:
1. Important for living and developing (economically, agriculturally, technologically)
2. Solving the problem of water pollution is the key to our better future.
3. Without water, there would be no life.
example: Marina Barrage, Singapore

Comments:
I felt like this project would fit me the most out of any other projects because in Japan, they are experiencing some heavy fresh water loss due to many natural disasters such as typhoons, nuclear power plant malfunction, and tsunamis; and one of the reasons why I wanted to become an environmental engineer was to help Japan with their reconstruction.

Environment:
1. Protecting Air, Land and Water overall
2. As a company, CDM Smith provides program support for Superfund cleanups, redevelop landfill and brownfields into community assets, apply novel techniques for the biodegradation of chlorinated compounds, preserve air quality, build and operate remediations and restoration systems, and restore and protect our fragile ecosystem.
example: Danang Airport, Vietnam

Comments:
From what I have heard, I would love to go to Danang Airport and see what’s different about this airport compare to all other airports that exist in our country. I have seen some airports that uses solar panels to be more conservative and energy efficient but I would like to see how environmental the airport is.

Transportation:
1. Important for linking communities and businesses, developing environmentally sensitive growth strategies, and improving economic prosperity
2. Transportation also helps with spreading information out through transportation.
example: George Bush Turnpike, Texas

Comments:
This is important because it helps people spread the information easier around the country as well as around the world. I feel like this is something we need to do. Share information on how to be more conservative and managing of our energy and environment.

Energy:
1. Because we need so much energy every day, we should be more conservative, managing, and use renewable sources
2. Without any energy, there would be no life and would have an extremely limited life.
example: Catawba County, Biomass

Comments:
I think this is the most important project in the world. As our population increases every single day, the amount of energy needed for people to survive increases. Cutting down trees and burning coals for energies are easy, however for our future generations, it’s only making them suffer with polluted air, unhealthy water, and etc.
It’s not my best interest but, if I had an opportunity to create a way to be more conservative and manageable, I would love to work in this project.

Facilities:
1. Construction of different facilities for different genres (industrial, military, etc)
2. Non-invasive sewer rehabilitation, environment-friendly urban landscaping, or complex geotechnical and seismic services.
example: Andrew Air Force base

Comments:
I went online to research about this “facilities” but I was not sure what they are specifically going to do. I would like to see more about this project.

About Employment Opportunities:
– There are offices around the world (worldwide)
– Need to have at least a Bachelor’s degree and  having Master’s is an advantage
– The company looks through each person’s summer work, how expressive, and academic record
– Starts at junior year and if you want to join, you should always look at the website and research
– There are an application opportunity from late winter. (around Jan, Feb)

Comments:
From what I have heard, I was very interested because the company helps the environment with water, energy, transportation and etc. However, when I heard that the company is “flat” due to the recession, I felt like it will stay like that for at least another 5 years. That worried me a little because I’m still not sure if I will be going straight to job searches or going for some master’s.


My Overall Opinion of the company:
Dr.Vicen’s lecture helped me learn about his company (CDM Smith) as well as what I should do to be successful with my future job searching. He also taught us how companies not only want smart and intellectual people but also very social and expressive engagers.
One of the things that surprised me the most was when Dr.Vicens explained to us that CDM Smith gives specific outline of how the company works, there are a lot of opportunities depending on what you favor  and how you can increase your pay/gain promotions. Most of the companies that I  have seen so far only talks about what they are expecting out of the employees and how much they will pay; instead, CDM Smith wants the workers to suggest what they should do and how they should run.

From what I have seen, i think the company is very welcoming and very open to new ideas as well as future developments. Their ideas and their motto give an amazing impression to me because I want to develop our world into a more uniformed and peaceful world because if we do not work together to make this world a better place,  and I feel like CDM Smith is trying to accomplish that.
