Which of the following characteristics relates to kerberos? a. a computer network authentication protocol that allows nodes communicating over a non-secure network to prove their identity to one another in a secure mannerb. a public interest research group in washington, d. c., established in 1994 to focus public attention on emerging civil liberties issues and to protect privacy, the first amendment, and constitutional values in the information agec. a round-robin database tool intended to handle time-series data like network bandwidth, temperatures, cpu load, and so on. d. dynamic random access memory (dram) that has a synchronous interface

In a heat transfer course, we can derive the equation for the temperature distribution in a flat rectangular plate. in this example, we will look at a plate at steadystate with three sides being held at t1, and one side held at t2. the temperature for any location on the plate, t(x,y), can be calculated by where create a function (prob3_5) that will take inputs of vectors x and y in feet, scalar n, scalars l and w in feet and scalars t1 and t2 in degrees fahrenheit. it will output a matrix t which is the temperature of each x and y locations. t will have the number of columns equal to the number of elements in x and rows equal to the number of elements in y. though this can be done without loops (perhaps more efficiently), your program must use a nested loop.
