BJT Theoretical: - What are the three modes of the operation of BJTs ? How to force a BJT to operate in each of the three modes of operation ? - Use iC ∼ vBE to identify the region where BJTs operate in (i) cut-off mode and (ii) active mode. - Show the large-signal equivalent circuit of a BJT biased in active mode. - The base current of a BJT consists of two distinct components, what are they ? -...
What are the five major categories of fraudulent disbursements? Pick two of the categories and describe: a. How the fraudulent disbursement occurs, b. Three red flags associated with the fraudulent disbursement category: C. Three methods used by forensic accountants to detect the fraudulent disbursement.
(a) Discuss the 'two main modes of operation of an atomic force microscope (AFM). [6 marks) (b) Draw a fully labelled graph representing the variation in the pair-potential energy (E pair) with separation r between two atoms as described by the Lennard-Jones function, where, Epair (r) = 48 --[09-0"] Comment on the terms present within the function and what they can be attributed to. By means of calculus, calculate the separation r between two atoms that minimises the function and...

6. [10 pts.] Suppose a computer system works in two modes of operation: a sleep mode, A', where it is under-utilized and working mode A where it is adequately utilized. Every hour the computer system changes its state according to the following state diagram: 0.2 0.1 a. Finish labeling the transition on the state diagram. b. Give the corresponding probability matrix. c. What are the probabilities of being in the states A and A' after 3 hours of work. Suppose...
