When purifying drinking water you can use a so-called membrane filtration. In an experiment one wishes to examine the relationship between the drop across a membrane and the flux (flow per area) through the membrane. We observe the following 10 related values of pressure (x) and flux (y): pressure 2 3 4 5 6 7 8 9. 10 Pressure (x) 1.02 2.08 2.89 4.01 5.32 5.83 7.26 7.96 9.11 9.99 Flux (y) 1.15 0.85 1.56 1.72 4.32 5.07 5.00 5.31 6.17 7.04 Copy this into R to avoid typing in the data: D <- data.frame( pressure=c(1.02,2.08,2.89,4.01,5.32,5.83,7.26,7.96,9.11,9.99), flux=c(1.15,0.85,1.56,1.72,4.32,5.07,5.00,5.31,6.17,7.04)

While each of us has had a reading of our blood pressure taken, many of us may not know what blood pressure actually means. Blood pressure is expressed as a ratio of the maximum (systolic) and minimum (diastolic) pressure found in the aorta during one cardiac cycle. These pressure values are measured in millimeters of mercury (mmHg). Determining abnormal blood pressure is critical for diagnosing and averting a number of serious health problems (e.g. heart disease and stroke). Doctors therefore make decisions about the potential for serious health problems based on a few simple calculations. One simple calculation of interest is mean arterial pressure (MAP). The mean arterial pressure is the average pressure during the cardiac cycle. The MAP of a normal, resting heart can be computed by the formula: MAP = DP + (1/3)PP where DP is the diastolic pressure and PP is the pulse pressure. Create a Java class file called MeanArterialPressure. This program will compute a user's mean arterial…

Doctors therefore make decisions about the potential for serious health problems based on a few simple calculations. One simple calculation of interest is pulse pressure (PP). The pulse pressure of an individual can be computed as the difference between the systolic and diastolic pressures. Create a Java class file called PulsePressureIST140. This program will compute a user's pulse pressure based on two inputs: the systolic pressure (a int value) and the diastolic pressure (an int value). Once the input is…
A standard science experiment is to drop a ball and see how high it bounces. Once the “bounciness” of the ball has been determined, the ratio gives a bounciness index. For example, if a ball dropped from a height of 10 feet bounces 6 feet high, the index is 0.6 and the total distance traveled by the ball is 16 feet after one bounce. If the ball were to continue bouncing, the distance after two bounces would be 10 ft + 6 ft + 6 ft + 3.6 ft = 25.6 ft. Note that distance traveled for each successive bounce is the distance to the floor plus 0.6 of that distance as the ball comes back up. Write a program that lets the user enter the initial height of the ball and the number of times the ball is allowed to continue bouncing. Output should be the total distance traveled by the ball. Please name your function "bounce" that has three arguments (initial height, index, number of bounce) and return the total distance traveled by the ball. (float) Skip the part where users can enter the inputs of…
The voltage V(1) (in V) and the current i(t) (in Amp) t seconds after closing the switch in the circuit shown are given by: R Vdt) = V(1– e/) i(t) = e, where t, = RC is the time constant. Consider the case where V = 24 V, R = 3800 2 and C = 4000 x 10-6 F. Determine the voltage and the current during the first 20 s after the switch is closed. Create a vector with values of times from 0 to 20 s with spacing of 2 s, and use it for calculating V(1) and i(t). Display the results in a three-column table where the values of time. voltage and current are displayed in the first, second, and third columns, respectively.
