Social network analysis is a technique that attempts to
a. analyze large data warehouses to detect changes deemed important by a user
b. allow hypothetical changes to the data associated with a problem and observe how these changes influence the results
c. find groups of people who work together
d. analyze why a key indicator is not at an appropriate level or why an exception occurred
e. discover hidden predictive relationships in the data

When keyboarding, if you want to be fast and accurate you should return your hands on home row with your fingers relaxed and your eyes on the text use only your index fingers to hunt and peck keep your fingers stiff and your eyes on the keys slouch in your chair and keep your fingers hovering over all of the keys

3. (6 pts) internally in the computer, with few exceptions, all numerical computation is done using binary numbers. output, however, often uses ascii, which is formed by appending 011 to the left of a bcd code. thus, an algorithm that directly converts a binary integer to a bcd integer is very useful. here is one such algorithm 1) draw lines to the left of the binary number to bound the expected bcd decades. (each decade is a group of 4 bits.) move the binary number one bit to the left. add 0011 to each bcd decade containing a binary value> 0100 repeat steps 2-3 until the last bit in the binary number has been moved into the least significant decade position. (note that when the last bit has been shifted into bcd decade, step 3 is not repeated.) read the bcd result. 2) 3) 4) 5) a) execute the algorithm for the binary number 1101101 b) execute the algorithm for the binary number 01110101110 4. (4 pts) represent the decimal number 3568 in bcd; excess-3 code; ascil; and hex.

Let r be a robotic arm with a fixed base and seven links. the last joint of r is a prismatic joint, the other ones are revolute joints. give a set of parameters that determines a placement of r. what is the dimension of the configuration space resulting from your choice of parameters?
