Question 8: Designing an 8×8 Pixel Grid System (M3) The Engineering Department at Riyadh Tech Solutions is exploring the use of an 8×8 pixel grid for a graphical display or LED matrix. You are tasked with evaluating the coordinate system and programming considerations for this output device. Specifically, you need to address the following factors: • Resolution factors: Analyze how the 8×8 resolution impacts the clarity and detail of the displayed content. • Pixel addressing factors: Determine the most efficient method for addressing individual pixels in the grid, considering row-column indexing or linear addressing. • Programming factors: Evaluate the ease of programming the grid, including the use of libraries, APIs, or custom code to control pixel states (on/off) and display patterns. Hint: • For resolution, consider the limitations and advantages of an 8×8 grid for displaying simple graphics or text. • For pixel addressing, explore how row-column pairs (e.g., (x, y)) or linear indices (e.g., 0 to 63) can be used to access pixels. • For programming, investigate tools like Arduino libraries for LED matrices or Python libraries for graphical displays to simplify development.

(Gambler’s Ruin) Consider a coin-flipping game with two players where player one wins each toss with probability p, and player two wins with probability q = 1 − p. Suppose player one has n1 pennies and player two n2 pennies. Assuming an unfair coin (ie, p ̸= 1/2), the probabilities p1 and p2 that players one and two, respectively, will end penniless are

An electrical current $J_0$ induced to flow in a metallic ring in absence of electric field will decay as $J = J_0 exp(-t/\tau)$ where $\tau$ is the relaxation time which is also the collision time in the free electron model of metals. For a good metal, $\tau$ is of the order of $10^{-8}$ sec at low temperatures. The same experiment conducted with a superconducting ring shows no decay of current after a year. If the accuracy of the current measurement is 0.01 percent, calculate the lower limit for the relaxation time.
