F $F_o$ M B $C_s$ $C_p$ $x_1$ $x_2$ Figure 4: A Linear Lumped-Element Model of the Skeletal Muscle Mechanics. An oversimplified, linear model of skeletal muscle mechanics is shown in Figure 4. In this model, • M represents the muscle mass, • B represents the viscous damping inherent in the tissue • $C_p$ (parallel elastic element) and $C_s$ (series elastic element) reflect the elastic storage properties of the sarcolemma and the muscle tendons, respectively. These elements are modeled as springs. Note that the elastic storage parameter C and the spring constant k are related to each other as: k = 1/C. • $F_o$ represents the force developed by the active contractile element of the muscle. You may consider this element to be a force generator, and take the direction of the arrow as the direction of this force. For this model, the input is defined as the force F, and the output is $x_2$. Given these information, obtain, 1. The differential equation representation for the model, 2. The transfer function of the model when $F_o$ = 0.

A stock recently has been estimated to have a beta of 1.40: Required: What is the “adjusted beta” of this stock? Note: Do not round intermediate calculations. Round your answer to 2 decimal places. Suppose that you estimate the following regression describing the evolution of beta over time: βt = 0.4 + 0.6βt–1 What would be your predicted beta for next year? Note: Do not round intermediate calculations. Round your answer to 3 decimal places.

Mark’s on the Park (MOP) is a highly successful restaurant known for their weekend brunch. Given the success of the restaurant, one of Mark’s friends, Mr. Lowe, asked for some financial help to open a similar restaurant in a nearby town. The following events relate to the loan from MOP to Mr. Lowe: On March 1, Year 1, MOP loaned Mr. Lowe $60,600 for one year at 5 percent interest. On December 31, Year 1, MOP recognized accrued interest on the loan. On March 1, Year 2, MOP recognized accrued interest. On March 1, Year 2, MOP recognized the collection of the note including all interest. On March 1, Year 1, MOP loaned Mr. Lowe $60,600 for one year at 5 percent interest.

Option 1: Since the small island has been hurt by a downturn in tourism, we could help the economy by providing a one-time tax for the pollution. This would present an immediate carbon offset of $13,000,000. I know some of the senior members of the management would like to use this as a marketing tool and know the money could be used to help the local government fund items that were cut because of previous missed tax revenues from the lack of tourism to the island. Option 2: The power plant could be shut down completely and we could install a power cable that runs from one of the other nearby islands that has a power plant. This power plant will still.

[Question 1] – This question carries 7 marks As a network engineer, you have been requested to create a subnetting scheme for the company with the following network structure. The number of hosts for the user networks is displayed in the figure. The company received the address block 209.166.100.0/24 from the ISP. Create a detailed analysis plan that addresses the following points: A. Determine the LANs and WANs that are required in this topology (give the full list). Determine the number of subnets required to connect all the links (LANs and WANs). B. Determine the required number of IPs for each subnet (link). Explain in detail. C. Evaluate if the given address block is sufficient to cover all the IPs requirements in this topology. D. Explain the details of CIDR to be applied on the address block to create the required subnets with the least amount of address wasting. E. For each subnet, describe and determine the following (use a table for better demonstration): 1. The subnet mask 2. The broadcast IP address 3. The subnet (network) IP address 4. The first usable host IP address 5. The last usable host IP address F. What are the consequences if you use classful addressing for this scenario? Discuss in detail. Your Answer: [Question 2] – This question carries 3 marks Why is DHCP essential in internetworking? Discuss in detail (supported by a figure) the concept of DHCP Failover and its implementation.
