Use case diagram A use case diagram at its simplest is a representation of a user’s interaction with the system that shows the relationship between the user and the different use cases in which the user is involved. A use case diagram can identify the different types of users of a system. The different use cases and will often be accompanied by other types of diagrams as well.

CHAPTER 4 HARDWARE DESCRIPTION 4.0 Arduino: The Arduino Uno is a microcontroller based on the ATmega328. It has 14 digital input/output pins in which 6 can be used as PWM‚ 6 analog inputs‚ a 16 MHz ceramic resonator‚ a USB port‚ a power jack‚ an ICSP header‚ and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.[11] The Uno differs from all preceding boards in

The Polar Bear (Ursus maritimus) is a bear native largely within the Arctic Circle encircling the Arctic Ocean‚ its surrounding seas and land masses. Although it is closely related to the Brown Bear‚ it has evolved to occupy a narrower ecological forte‚ with many body characteristics adapted for cold temperatures‚ for moving across snow‚ ice‚ and open water‚ and for hunting the seals which make up most of its diet. Though there are many theories surrounding evolution‚ the two stand outstanding hypotheses

We don’t have to worry about things like polar ice caps melting and flooding the entire earth because‚ frankly‚ it isn’t going to effect us. We can go on in comfort knowing that tomorrow the sun will rise and with it‚ bring another four hours of gridlock traffic‚ eight hours confined to

B) In 2007 there was a massive polar ice melt and the amount of glaciers and sea ice has decreased quite a bit since the 70’s. This has already caused the sea levels to rise. C) The U.N. panel on climate change projects that by the end of this century the global temps. will have risen 3-10 degrees. Enough to melt the rest of the polar ice caps. And it

The thinner the ice gets the faster it melts. Besides the shrinking‚ the arctic sea ice is also forming later and later every year. This is directly impacting the polar bears that depend on the ice for survival. Over a twenty four year period the average weight of female polar bears has decreased by 143 pounds
