1 REQUIREMENTS You will need to complete the following tasks and deliver your finding in a written report by August 6th. Research the six scenarios given below in option 1 for added capacity to uncover any additional costs/benefits to society these options might pose. Write a two page summary describing each scenario. Discuss the pros and cons of each scenario, including such items as renewable sources of fuel, environmental factors, etc. Give examples of each type of project by name and location and indicate the sources of your information. Please use either IEEE or APA style. Do an economic analysis of the six scenarios. Use a 20-year period and assume an inflation rate of 4 percent. Include your calculations and any assumptions in the report. Also answer the following questions: Which scenario is the best from an economic basis? Are there any other considerations, such as environmental/health/social issues, which should be considered? Which scenario have you selected based on the answers to a and b? What is the estimated timeframe to implement the different options? (base your timelines on existing projects of similar size if possible, use MS Project/Project Libre to generate the timelines) Make a recommendation regarding the best option for the utility. 2 Situations A utility company in one of the western states is considering the addition of 50 megawatts of generating capacity to meet expected demands for electrical energy by the year 2025. The three options that the utility has are: Add generating capacity. Constructing one of the scenarios below would do this. Purchase power from Canada under terms of a 20-year contract. Do neither of the above. This assumes that brownouts will occur during high demand periods. The utility presently has 200 megawatts of installed capacity and generates an average of 1.2 billion kilowatt-hours annually. Maximum generation capability is 1.3 billion kW-hours. By the year 2025, this reserve of 100,000,000 kW-hours will be used. 2.1 OPTION 1 – ADD GENERATING CAPACITY For this option there are six possible scenarios: Hydroelectric dam. Initial cost is $ 50 million. Annual operating and maintenance cost is $ 1.7 million. Project life is 30 years before a major rebuild is required. Wind farm. Initial cost is $ 28 million. Annual operating and maintenance cost is $ 2.5 million. Project life is 12 years. At this time new equipment will be required. Solar power. Initial cost is $ 32 million. Annual operating and maintenance cost is $ 1.1 million. Project life is 10 years. Natural gas turbines. Initial cost is $ 14 million. Annual operating and maintenance cost is $2.0 million. Project life is 12 years. Nuclear plant. Initial cost is $ 70 million. Annual operating and maintenance cost is $ 2.0 million. Project life is 25 years. Coal-fired turbines. Initial cost is $ 35 million. Annual operating and maintenance cost is $ 2.7 million. Project life is 28 years. 2.2 OPTION 2 – BUY POWER FROM CANADA The annual additional energy requirement is 350,000,000 kilowatt-hours. The cost of energy from Canada is 1.48 cents per kilowatt-hour for the first year. The price will be escalated at 4 percent annually for the 20-year contract period. 2.3 OPTION 3 – DO NOTHING Local municipalities are very opposed to this option since companies may have to close down for short periods of time. Also, it would be very difficult to attract new businesses. If nothing is done, by the year 2025 it is anticipated that some companies will be without power for short periods of time during the summer months. These are known as brownouts. It is estimated, based on historical data that these outages will occur once a week during July and August for periods of 6 hours.

The following equation can be used to compute values of y as a function of x: y = b  e?ax  sin(b  x)  (0:012  x4 ? 0:15  x3 + 0:075  x2 + 2:5  x) where a and b are parameters. Write the equation for implementation with MATLAB, where a = 2, b = 5, and x is a vector holding values from 0 to =24 in increments of x = =40. Employ the minimum number of periods (i.e., dot notation) so that your formulation yields a vector for y. In addition, compute the vector z = y2 where each element holds the square of each element of y. Combine x, y, and z into a matrix w, where each column holds one of the variables, and display w using the short g format. In addition, generate a labeled plot of y and z versus x. Include a legend on the plot (use help to understand how to do this). For y, use a 1:5-point, dashdotted red line with 14-point, red-edged white-faced pentagram-shaped markers. For z, use a standard-sized (i.e., default) solid blue line with standard-sized, blue-edged, green-faced square markers.

10.2 California Imaging Center, a not-for-profit business, is evaluating the purchase of new diagnostic equipment. The equipment, which costs $600,000 has an expected life of five years and an estimated salvage value of $200,000 at that time. The equipment is expected to be used 15 times a day for 250 days a year for each year of the project’s life. On average, each procedure is expected to generate $80 in cash collections during the first year of use. Thus, net revenues for Year 1 are estimated at 15 X 250 X $80 =$300,000. Labor and maintenance costs are expected to be $100,000 during the first year of operation, while utilities will cost another $10,000 and cash overhead will increase by $5,000 in Year 1. The cost for expendable supplies is expected to average $5 per procedure during the first year. All costs and revenues are expected to increase at 5 percent inflation rate after the first year. The center’s corporate cost of capital is 10 percent. a. Estimate the project’s net cash flows over its five-year estimated life. (hint: use the following format as a guide.) Year 0 1 2 3 4 5 Equipment Cost Net revenues Less: labor/maintenance costs Utilities cost Supplies Incremental overhead Operating income Equipment salvage value Net cash flow b. What are the project’s NPV and IRR? (Assume for now that the project has average risk.) c. Assume the project is assessed to have high risk and California Imaging Center adds or subtracts 3 percentage points to adjust for project risk. Now, what is the project’s NPV? Does the risk assessment change how the project’s IRR is interpreted?

Biomedical Signal and Image Processing (4800_420_001) Assigned on September 12th, 2017 Assignment 4 – Noise and Correlation 1. If a signal is measured as 2.5 V and the noise is 28 mV (28 × 10−3 V), what is the SNR in dB? 2. A single sinusoidal signal is found with some noise. If the RMS value of the noise is 0.5 V and the SNR is 10 dB, what is the RMS amplitude of the sinusoid? 3. The file signal_noise.mat contains a variable x that consists of a 1.0-V peak sinusoidal signal buried in noise. What is the SNR for this signal and noise? Assume that the noise RMS is much greater than the signal RMS. Note: “signal_noise.mat” and other files used in these assignments can be downloaded from the content area of Brightspace, within the “Data Files for Exercises” folder. These files can be opened in Matlab by copying into the active folder and double-clicking on the file or using the Matlab load command using the format: load(‘signal_noise.mat’). To discover the variables within the files use the Matlab who command. 4. An 8-bit ADC converter that has an input range of ±5 V is used to convert a signal that ranges between ±2 V. What is the SNR of the input if the input noise equals the quantization noise of the converter? Hint: Refer to Equation below to find the quantization noise: 5. The file filter1.mat contains the spectrum of a fourth-order lowpass filter as variable x in dB. The file also contains the corresponding frequencies of x in variable freq. Plot the spectrum of this filter both as dB versus log frequency and as linear amplitude versus linear frequency. The frequency axis should range between 10 and 400 Hz in both plots. Hint: Use Equation below to convert: Biomedical Signal and Image Processing (4800_420_001) Assigned on September 12th, 2017 6. Generate one cycle of the square wave similar to the one shown below in a 500-point MATLAB array. Determine the RMS value of this waveform. [Hint: When you take the square of the data array, be sure to use a period before the up arrow so that MATLAB does the squaring point-by-point (i.e., x.^2).]. 7. A resistor produces 10 μV noise (i.e., 10 × 10−6 V noise) when the room temperature is 310 K and the bandwidth is 1 kHz (i.e., 1000 Hz). What current noise would be produced by this resistor? 8. A 3-ma current flows through both a diode (i.e., a semiconductor) and a 20,000-Ω (i.e., 20-kΩ) resistor. What is the net current noise, in? Assume a bandwidth of 1 kHz (i.e., 1 × 103 Hz). Which of the two components is responsible for producing the most noise? 9. Determine if the two signals, x and y, in file correl1.mat are correlated by checking the angle between them. 10. Modify the approach used in Practice Problem 3 to find the angle between short signals: Do not attempt to plot these vectors as it would require a 6-dimensional plot!
