Matlab model using normal equations model to analyze the body's response to a bolus injection of antibiotic

(See attached file for full problem description) --- This model is used to analyze the body's response to a bolus injection of this antibiotic: B(t) = B0e(-k*t) Using this model, and data provided for the average plasma concentration data in ug/ml with time in hours : a) perform linear regression on this penicillin clearance using the normal equations b) plot the concentration data and re-plot the log of the concentration data to show that it appears linear. c) Determine initial concentration, B0, and elimination rate constant, k Concentration (ug/ml) Time (min) 89 22 60 44 30 88 15 132 7 176 a) for linear regression ln( B ) = ln( B0 )- Kt I'm not sure how to use... click for more

MATLAB polyfit find P50 in mmHg

How do I convert back to find P50 in mmHg and n given the best-fit? function po2() %This function tests the linearty of tetrameric bovine hemoglobin binding %to oxygen as a possible blood substitute for monomeric hemoglobin. An %oxygen dissociation curve is created, and a linear regression is performed %on the experimental data using the built in Matlab function, polyfit. A %best-fit model is plotted with the data to show that linearty exists. % this is the data provided pO2 = [ 10 20 30 40 50 60 70 80 90 100 110 120 ] ; Y = [0.18 0.4 0.65 0.8 0.87 0.92 0.94 0.95 0.95 0.96 0.96 0.97 ] ; % Test the linearity according to Henry's Law and the Hill equation %ln(Y/(1-Y)... click for more

Matlab script for statistics and histogram

(See attached file for full problem description) Any help is greatly appreciated, as the script I wrote does not seem to be deciphering between the two sets of data. --- Write a Matlab script using the "randn" command to generate a vector of 10,000 random numbers that are normally distributed around zero, with a variance of 1. Use the "hist" command to plot a histogram of these data, specifying 50 bins. Use "find" command to determine what percentage of the data points lie within 1 standard deviation of the mean (which is zero). Redo this analysis for a smaller set of data (20 points) and reduce number of bins in the histogram. ---

java program

Write a program that reads a social security number written as contiguous digits (for instance, 509435456), uses the charAt method to obtain each character and then prints each digit on a separate line followed by a colon and the digit printed the number of times equal to its value. Thus the output for 509435456 would be 5:55555 0: 9:999999999 4:4444 3:333 5:55555 4:4444 5:55555 6:666666 Hint: Use a char variable,e.g., index, for the inner loop control variable and write the inner loop as for(char index = '1'; index <= digit; index++) where digit is the char variable used to store the digit taken from the string.

Java Programming

In Code3 there are (6) numbered items. The first four are "compiler errors." Include a separate Word document with your assignment and explain why each will produce a compiler error and what you would do to fix the problem. Explain what is happening in 5 and 6 and why this code will prevent a possible compiler error. // This program illustrates the use of Java datatypes. import java.io.*; import java.lang.*; public class Code3 { //begins Nums public static void main(String args[]) { int x= 5; int y= 2; int z = 0; long a, b = 0; double d= 5.12345; byte c = 0; //float e = 34.2; compiler error: (1) float e = 34.2F; //or float e = (float) 34.2; short f,... click for more
