QUESTION 22 Because of the rising costs of industrial accidents, many chemical, mining, and manufacturing firms have instituted safety courses. Employees are encouraged to take these courses designed to heighten safety awareness. A company is trying to decide which one of two courses to institute. To help make a decision eight employees take course 1 and another eight take course 2 . Each employee takes a test which is graded out of a possible 25 . The safety test results are shown below. Assume that the scores are normally distributed. Do these data provide sufficient evidence at the 5% level of significance to infer that the marks from course 1 and course 2 are different? able[[Course 1,Course 2],[14,20],[21,18],[17,22],[14,15],[17,23],[19,21],[20,19],[16,15]] What is the appropriate test to perform?

2. Alice sends an email to Bob that she wants to be reasonably certain other people do not see. Discuss security methods, if any, one might use in the cases below. Indicate why these methods are needed for the specific scenario; in particular, discuss your solution in terms of the desired security goals. • Alice and Bob are at the same company location on a protected network • Alice emails Bob, who is at a public hotspot • Alice emails Bob; they are at separate company locations each on a protected network Feel free to define what “protected network” means if it matters. 3. Suppose Alice and Bob share a long-term master key, and that is all they share. • Show how Alice can send a message to Bob that satisfies confidentiality and integrity. Describe the steps explicitly. Mention which algorithms you are using. [If you appeal to an existing protocol, you must indicate why it is appropriate and still answer the questions.] • Indicate the steps that Bob needs to do when he receives the message. • Why was this method not considered when we discussed email security? What aspects of email makes this method difficult to realize in practice?

51. TRUE FALSE Antidiuretic hormone (ADH) regulates water permeability of the proximal convoluted tubule. 52. TRUE FALSE Dilation of the efferent glomerular arteriole would increase glomerular pressure and glomerular filtration. 53. TRUE FALSE Low blood glucose triggers insulin secretion. 54. TRUE FALSE Inulin clearance can provide a measurement of the glomerular filtration rate. 55. TRUE FALSE ADH secretion is stimulated when osmoreceptors in the hypothalamus detect a decrease in blood osmolality. 56. TRUE FALSE Antidiuretic hormone elicits the expression and insertion of aquaporins into the collecting duct. 57. TRUE FALSE Vasopressin (antidiuretic hormone, ADH) induces renal water elimination. 58. TRUE FALSE The partial pressure of oxygen decreases at high altitude but the fraction of oxygen in the air remains constant. 59. TRUE FALSE Eating lots of salt with your meals will decrease your aldosterone levels. 60. TRUE FALSE Normal mammalian blood pH varies between 6.05 - 6.25.

1. A 3-month-old boy presents with poor feeding and growth, low muscle tone (hypotonia), elevation of blood lactic acid (lactic acidemia), and mild acidosis (blood pH 7.3-7.35). The ratio of pyruvate to lactate in serum is elevated, and there is decreased conversion of pyruvate to acetyl coenzyme A in fibroblasts. Which of the following compounds should be considered for therapy? A. Thiamine B. Pyridoxine C. Free fatty acids D. Biotin E. Ascorbic acid 2. Which one of following statements about glycogen synthesis and utilization is CORRECT? A Liver synthesizes more glycogen when the hepatic portal blood concentration of glucose is high because of the activity of glucokinase in the liver. B. Glycogen reserves in liver and muscle will meet energy requirements for several days in prolonged fasting. C. Glycogen is synthesized in the liver in the fed state, then exported to other tissues in low-density lipoproteins. D. Muscle syntheses glycogen in the fed state because glycogen phosphorylase is activated in response to insulin. The plasma concentration of glycogen increases in the fed state.

Consider the state-space model \begin{equation*} \dot{x} = \begin{bmatrix} -5 & 1\\ 14 & 0 \end{bmatrix} x + \begin{bmatrix} 1\\ 1 \end{bmatrix} u, \end{equation*} \begin{equation*} y = \begin{bmatrix} 1 & 0 \end{bmatrix} x. \end{equation*} Suppose we want to apply a full-state feedback controller of the form $u = -Kx$. 1. Find the open-loop eigenvalues (without computing the transfer function). 2. Select $K$ such that the closed-loop eigenvalues are placed at the roots of $\lambda^2 + 2\zeta\omega_n\lambda + \omega_n^2 = 0$. 3. Use your analytic expression, in terms of $K$, from part (2) to support the following claim: \"Moving the eigenvalues far away from the imaginary axis, thus making the closed-loop system dynamics fast, requires larger gains. Hence, for fast closed loop dynamics, we need to invest a relatively large amount of control effort.\" 4. Select $K$ to place the closed-loop eigenvalues at $\lambda = -9$ and $\lambda = -4$.
