Scenario description: assume you got a new wireless sensor device with circuit power consumption of p_elec = 0.015mw. frequency bandwidth (i. e. symbol rate) is 1mhz. you have a packet with 125 bytes to send. assume there is no other overhead, and you can ideally turn on and off the transmission without additional power cost. now you can choose using various data rates to transmit this packet, while maintaining the same ber at 0.0001 with the following assumption: using bpsk, the required tx amplifier power consumption of p_t =0.02mw; using qpsk, the required tx amplifier power consumption of p_t =0.05mw. receiver energy consumption is not a concern. questions: calculate the energy consumption (in unit of nj – nano-joule) of transmitting this packet, using bpsk and qpsk schemes, respectively. do you prefer slow bpsk transmission to save power, or to transmit quickly with qpsk and then sleep?

Dean wants a quick way to look up staff members by their staff id. in cell q3, nest the existing vlookup function in an iferror function. if the vlookup function returns an error result, the text “invalid staff id” should be displayed by the formula. (hint: you can test that this formula is working by changing the value in cell q2 to 0, but remember to set the value of cell q2 back to 1036 when the testing is complete.)

Consider the following function main: int main() { int alpha[20]; int beta[20]; int matrix[10][4]; . . } a. write the definition of the function inputarray that prompts the user to input 20 numbers and stores the numbers into alpha. b. write the definition of the function doublearray that initializes the elements of beta to two times the corresponding elements in alpha. make sure that you prevent the function from modifying the elements of alpha. c. write the definition of the function copyalphabeta that stores alpha into the first five rows of matrix and beta into the last five rows of matrix. make sure that you prevent the function from modifying the elements of alpha and beta. d. write the definition of the function printarray that prints any onedimensional array of type int. print 15 elements per line. e. write a c11 program that tests the function main and the functions discussed in parts a through d. (add additional functions, such as printing a two-dimensional array, as needed.)

Which of these is a benefit of using objects in a powerpoint presentation? a. collaborators can create the external files while you create and edit the slide show. b. you can easily change the theme and design of the presentation. c. you can have older data in the source file while having up-to-date data in the presentation. d. collaborators can easily share the presentation.
