Exercise 5.2.7 Find a linearly independent set of vectors that has the same span as the given vectors. \begin{bmatrix} 1\\3\\3\\1 \end{bmatrix}, \quad u_2 = \begin{bmatrix} 2\\6\\6\\2 \end{bmatrix}, \quad u_3 = \begin{bmatrix} 0\\-3\\-3\\1 \end{bmatrix}, \quad u_4 = \begin{bmatrix} 1\\2\\1\\1 \end{bmatrix}. Exercise 5.2.8 Here are some vectors in $\mathbb{R}^4$. $\begin{bmatrix} 1\\1\\-1\\1 \end{bmatrix}, \quad u_2 = \begin{bmatrix} 1\\2\\-1\\1 \end{bmatrix}, \quad u_3 = \begin{bmatrix} 1\\-2\\-1\\1 \end{bmatrix}, \quad u_4 = \begin{bmatrix} 2\\0\\1\\1 \end{bmatrix}, \quad u_5 = \begin{bmatrix} 1\\-1\\-1\\1 \end{bmatrix}. Explain why these vectors cannot possibly be linearly independent. Then obtain a linearly independent subset of these vectors that has the same span as these vectors.

3. Checking Inverses. Consider the functions with domain R and codomain R: $f(x) = \frac{2x - 3}{4}$, $g(x) = \frac{4x + 3}{2}$. Show that these are inverses of each other by evaluating $(g \circ f)(x)$ and $(f \circ g)(x)$ for a general input $x$. (Note that for both the output should simply be $x$, since inverses \"undo\" each other.)

6. Suppose you are in charge of a toll bridge that costs essentially nothing to operate. The demand for bridge crossings Q is given by $P = 15 - \frac{1}{2}Q$. a. Draw the demand curve for bridge crossings. KEY b. How many people would cross the bridge if there were no toll? KEY c. What is the loss of consumer surplus associated with a bridge toll of $5? KEY d. The toll-bridge operator is considering an increase in the toll to $7. At this higher price, how many people would cross the bridge? Would the toll-bridge revenue increase or decrease? What does your answer tell you about the elasticity of demand? KEY e. Find the lost consumer surplus associated with the increase in the price of the toll from $5 to $7. KEY

Assignment 3, ELE4363 Power Electronics Name: ID.: 1. An SCR is switched ON for 3 cycles then OFF for 7 cycles continuously, if the supply voltage is 230 V rms and the load is 30$\Omega$ pure resistive find the rms current and power delivered to load. [2 marks] 2. A single-phase ac voltage controller has a 230-V rms 50-Hz source. The load resistance is 30$\Omega$. Determine: (a) the delay angle required to deliver 500 W to the load, (b) the rms source current, (c) the rms and average currents in the SCRs, (d) the power factor. [4 marks] 3. For a single-phase voltage controller, the source is 230 V rms at 50 Hz, and the load is a series RL combination with R =30 $\Omega$ and L =50 mH. The delay angle $\alpha$ is 90°. Determine: (a) an expression for load current for the first half-period, (b) the rms load current, (d) the average SCR current, (c) the rms SCR current, (e) the power delivered to the load, (f) the power factor.

16. There are 97 members of the UNCITRAL. 17. Unfortunately, The Convention on the Recognition and Enforcement of Foreign Arbitral Awards (New York Convention) has fewer than 50 members. 18. The Nicaragua Case rejects arbitration since the contract as a whole is in question. 19. Italy is not yet a member state of the UNCITRAL but it is a major trading nation. 20. The US ratified the UNCITRAL in 1968 long before the Texas Trading Co. case that dealt with contracts for cement.
