Scientists test whether different light colors influence plant growth. Which factor should be controlled?

A scientist discovers a cell lacking membrane-bound organelles. This organism is most likely:

(3 points for the correct answer; extra 1 bonus point if you have answered questions 1 to 3 correctly.) Use the method of undetermined coefficients to give a suitable form for , a particular solution of the following equation         

You are deciding between method of undetermined coefficients and variation of parameters for solving

 (Graduate Only)  Which, between TRNG and PRNG, would you consider, if you were only interested in:   High entropy.  High speed.  Low runtime noise. 

Hardware metering uses chip identifiers to recognize and trace individual ICs. The table lists four methods of providing such identifiers.  Identification method  Functional / nonfunctional  Reproducible / unclonable  (a) A serial number is laser-marked on the package.      (b) Added ring oscillators create a process-variation fingerprint.      (c) A unique value is stored in on-chip nonvolatile memory.      (d) Added redundant states create a chip-specific sequence of internal behavior.      Classify each method as functional or nonfunctional identification. For each nonfunctional method, also classify the identifier as reproducible or unclonable. Write “Not applicable” wherever that classification does not apply. (2 × 4 pts)

A semiconductor company is reviewing wafer-test results before packaging and shipment. In addition to the overall number of passing dies, the engineers are interested in spatial patterns of failure.  The wafer maps below show both the test result and the physical location of each die. Each square represents one die on equal-sized wafers. The letters show the test outcomes, while their positions show where the dies lie on the wafer.  Wafer A and Wafer B: G = passed die, F = failed die  Wafer A  Wafer B  G  G  G  G  G  F  G  G  G  F  G  F  F  F  G  G  G  G  G  G  G  F  F  G  G  G  G  F  G  G  G  G  G  G  G  G  G  G  G  G  G  G  G  G  G  F  G  G  G  F  Calculate the yield of each wafer from the maps. Then explain what the locations of the failed dies suggest about the defects on each wafer. ((2 + 2) × 2 pts)

 (Graduate Only) A counter is a sequential digital circuit that stores a binary value and updates that value on clock edges, usually by incrementing or decrementing according to control inputs, The Verilog module below is intended to implement a 2-bit counter with synchronous reset. The table shows four consecutive rising clock edges. Carry the value of q from one edge to the next.  module count2(input clk, input rst, input en,               output reg [1:0] q);   always @(posedge clk) begin     if (en)       q
