Robot Lab

The Professor distributed a robot kit to us on that day, and the assignment was to build the robot in a particular way. After building the robot correctly and testing it, we plugged the robot using a USB cable to the lap computer. Plugging the robot to a computer will give us the ability to program it, so that it moves forward and backward.

Several measurements and calculations were made to indicate the experiment results. The following table will show the results of the experiment:

Time

Power1,2

Rotation1,2

#of wheel turns

Distance/time

(m/s)

1sec

50watt,50watt

348,353

145.147

0.402

0.0708

5sec

30watt.30watt

827-828

229

These results show the purpose of that class, which was to calculate the power, rotations, speed, time and the number of wheel turns. We used a verity of rules to calculate the results, but some of them I did not use in the experiment, and these rules are average speed=Distance/time, average velocity=displacement/total travel time, average acceleration=change in velocity/time for change to occur.

Sawyer Library

     We went to a library tour last Thursday; several resources were explained to us by our tour guide. There were a sundry of recourses I found at Suffolk library, for example, printed books. We were trained to look up for any reference we need in Suffolk library.

 

Starting with the reference desk, simply you can look for racecourses from there. You may also borrow printed books for few hours. The library is equipped several computers and printers that might help you with your research. In addition, there are labtops to borrow from the library to help you with your research as well. Therefore, the reference disk is considered a huge help for Suffolk students.

Next, the most important part in my opinion was the online database. I can access the data base via Suffolk home page, then library link. It’s where I can look up for any reference I need, easily and rapidly. We were introduced to a whole new level of resources, which can help with my studies here at Suffolk. By looking for the author name or the article title I can save a lot of time, even if I don’t remember the article title I can just look through A-Z search method. If I weren’t looking for some particular article or book, I can just look into categories and see what I need. Filters can be used to reduce the search results. I can also email the results I found to myself.

To sum up, this was important to me because I knew where to look into and how to look into it, that could save me time and effort, even money sometimes.

Hurricane Sandy

Hurricane Sandy and Global
Warming

 

Hurricane Sandy is a frequent topic of academic discussions nowadays, especially if global warming were relevant or not. Global warming caused several effects on our environment, for instance, temperature raise, ice melting worldwide and sea level rise became faster than it used to be.

Hurricane Sandy was a strong and deadly hurricane, it happened in fall of 2012. It occurred at the east coast of United States, it was a tragedy at some states, and it went through some other states without a noticeable damage. Because of this massive damage we wanted to know whether we caused this terrible hurricane or it was naturally caused.

Some researchers found that the hurricane is somehow relevant and irrelevant to global warming at the same time. Basically what they meant that it didn’t happen because of the global warming. However, global warming made it worse. According to Andrew Freedman, “What is already clear, however, is that climate change very likely made Sandy’s impacts worse than they otherwise would have been.”

There was a study conducted by the Center for Climate and Energy Solutions suggested that weather change might drove Sandy inland.

There are slight diversities of some studies can be seen while looking through some researches. Therefore, what can be clear is that global warming made Hurricane Sandy just worse than it supposed to be in normal conditions. Normal conditions can be defined as the nature without the effect of global warming.

In conclusion, Hurricane Sandy did not occur because of global warming but it made Hurricane Sandy more destructive in many levels.
