An engineering students designs and builds a capacitor from some scrap iron. One piece of iron is a square with side lengths of 10 cm, while the other piece is a rectangle that is 20 cm long and 10 cm wide. The student knows they can keep the plates separated by a distance of 1.2 micrometers.

a. What is the capacitance of this setup?

b. If the capacitor is fully charged using a 1.5 V battery, how much charge is built up on the plates?

c. How much energy is stored?

d. After performing the experiment, the student inserts a dielectric with a k value of 1.2. What values would this change?

Objectives:

Design an electronic circuit to measure Celsius temperature.

Model the circuit with Multisim and validate its operating characteristics.

Design Requirements:

A need has arisen for an inexpensive electronic thermometer that will measure Celsius temperature over a specified range. The basis for the design is the property that the forward voltage of a diode decreases with increasing temperature and can be approximated by a straight-line linear equation. The feasibility as a transducer will be studied and the specifications are as follows:

                Input Temperature Range: 0^o C to 100^o C

                Realistic Circuit Output Voltage: 0 V to 10 V based on a calibration factor of 0.1 V/^o C

                Voltage Representing Temperature: 0 V to 100 V monitored by VCVS with a gain of 10

                Accuracy of ±0.5 ^oC at the two extreme input temperatures as measured at output of VCVS

                One 1N4148 diode to serve as the basis for the transducer

                No more than three 741 operational amplifiers (preferably two) and ± 15 V power supplies

                Resistor values as needed (Assume calibration to an accuracy of 3 significant digits.)

                One ideal voltage-controlled voltage source (VCVS) with a gain of 10 to monitor the output

Pg. 1       This page with data added as requested should be Page 1 of the report.

Pg. 2       The instructor will specify a bias current. Connect a DC Current Source across the diode.                Perform a Temperature Sweep from 0^o C to 100^o C and create a Multisim plot of diode voltage                 versus Celsius temperature for Page 2. Use the vertical intercept and the slope (dy/dx) to      determine the straight-line equation that describes the diode voltage as a function of the          temperature. Then solve for the temperature in terms of the diode voltage. List the results below.                                   

                Bias Current:      I.     II.     III.     IV.      V.                         

                Diode Voltage as a Function of Temperature:                                                          

                Temperature as a Function of Diode Voltage:

Pg. 3       Design a circuit to provide an output voltage in terms of input temperature. Add a Voltage Gain Block with a gain of 10 so that the ideal value of the output voltage is the input temperature. Show the Multisim schematic diagram of the circuit on Page 3.

Pg. 4      Use Temperature Sweep to obtain a Multisim plot of the output voltage versus input Celsius          temperature. Use cursors to measure the output at the two extreme input values.

SCIMS at USP wants to maintain student records using linked lists. The school currently offers 3 first-year courses which are CS100, CS101 and CS110. These courses are compulsory and are required by students to do in a semester. All courses have two assignments (20% each ), a mid-semester test (10%) and final exam (50%). The following file contains the students' records, course lists with appropriate marks. Student file contains students id number and name. Each course file contains students mark (assignment 1, assignment 2, MST and final exam). Beside each assessment in the file, the total mark for that particular assessment is given.

You are required to write a program for the school to do grade calculation and analysis using linked lists. The following criteria need to be used for grade calculation for each course:
Total Score Grade GPA
85 or more A+ 4.5
78 to 84 A 4
71 to 77 B+ 3.5
65 to 70 B 3
56 to 64 C+ 2.5
50 to 55 C 2
40 to 49 D 1.5
0 to 39 E 1
Please do note that if the student does not meet the minimum 40% mark in the final exam and the course total mark is above 50 then the student should be given a D grade.
Requirements
1. Draw the structure of the linked list using an appropriate tool with all relevant data from the file.
2. This problem must be solved using linked list. You have to use classes to create linked list.
3. The main program should be able to do the following:
 Create a linked list for each file and store the records of the file.
 Calculate the total mark and grade of a student for each course which must be stored in the list.
 Create a menu for the user that can do the following:
o Exit program
o Display all students for SCIMS
o Display the marks and grade for each course. The course code will be entered by the user.
o Display all students who got D grade because the minimum 40% was not met in the final exam. The display should include student ID, name, course code, total mark.
o Display all students who failed all three courses.
o Display students in each course who got A+.
o Calculate and display semester GPA for all students. Semester GPA is calculated by adding GPA for all courses and then divided by the number of courses.
o Delete a student record from all the linked lists. The program should prompt the student id number.
o Add a student record in all linked lists.
 Except the first menu, all others should be implemented using functions of the main program.

Prospective drivers who enroll in Smart Driver Driving School have always been taught by a conventional teaching method. The driving school has many branches across provinces. Last year, among all students that took driving lessons from the school in a certain province, 80% passed the provincial road test. This year, the teaching committee came up with a new teaching method. The committee randomly assigned half of its 2400 students enrolled this year to receive the conventional teaching method and the remaining half to receive the new teaching method. In a random sample of 100 students who received the conventional teaching method, 76% passed the road test.

C. The passing rate for students taught using the conventional method this year is the same as last years.

D. Both (b) and (c).

Snapchat is interested in targeting a particular audience group with a new product(Spectacles)and needs to know about the average time a first-year college student spends on Snapchateach day. This way, they can decide whether or not it would be worthwhile to advertise Spectacles to students. Unfortunately, the Snapchatreport does not include specific information about first-year college students, so they don't have u for this population. They hire Serena to find more information.
She does some research online and finds that Website A claims that first-year college students spend on average 4 hours on Snapchatper day and Website B claims that first-year college students spend on average 3 hours on Snapchatper day. Since both sites made different claims, Serena decides to survey first-year students at De Anza to create a confidence interval to decide if the claims are reasonable. The following is a list of 30 responses (in hours):

1. Input the 30 observations into the list 1L of your calculator and use 1-Var-Stats to determine the sample mean X and the sample standard deviation .sRound your answers to 4 decimal places. Again, assume X is approximately normal.
X=_____________ s= ________________
2. Explain in one sentence why the t distribution must be used to create a confidence interval in this situation.
3. Using the information from problems 2 and 3, construct a 95% confidence interval for the population mean the number of hours spent on Snapchatby first-year college students. Round your answer to 4 decimal places. Show all of your work and interpret the confidence interval.
4. Are the claims made by Website A and Website B reasonable or unreasonable? Make your decision based on your 95% confidence interval from problem 4 and explain.
A. Website A’s claim of u=4 hours is reasonable/unreasonable(circle one) because...
B. Website B’s claim of u=3 hours is reasonable/unreasonable(circle one) because...

A cohort study was undertaken to examine the association between high lipid level and coronary heart disease (CHD). Participants were classified as having either a high lipid level (exposed) or a low or normal lipid level (unexposed). Because age is associated with both lipid level and risk of heart disease, age was considered a potential confounder or effect modifier and the age of each subject was recorded. The following data describes the study participants: Overall, there were 11,000 young participants and 9,000 old participants. Of the 4,000 young participants with high lipid levels, 20 of them developed CHD. Of the 6,000 old participants with high lipid levels, 200 of them developed CHD. In the unexposed, 18 young and 65 old participants developed CHD.. Calculate the appropriate crude ratio measure of association combining the data for young and old individuals. 3. Now, perform a stratified analysis and calculate the appropriate stratum-specific ratio measures of association. What are they? 4. Do the data provide evidence of effect measure modification on the ratio scale? Justify your answer.

A researcher followed a cohort for 10 years after the Aliso canyon gas spill. The researcher interviewed 290 residents. 140 residents lived within a 2 mile radius of the leak and were classified as exposed and 150 residents lived more than 5 miles away and were considered unexposed. In total 120 of the 140 residents exposed to the gas developed respiratory problems and 10 of the 150 not exposed to the gas developed respiratory problems.
