I was asked to find the magnetic field of an infinite current sheet due to amperes law. Is my attempt to the solution correct ? The final answer is correct, but l am doubtful of how l got there.
I am a bit rusty on my integration techniques. Can someone please tell me which integration technique to use for this integral ? I don't want to anyone to solve it for me. I just want to be nudged in the right direction.
So l generated a 100 000 data sets in Matlab each consisting of 80 random poisson distributed numbers. I then calculated the p-values for each data set and stored them into a vector which l used to make this histogram. I was wondering, what distribution is shown by this histogram
So l have a nuclear counting system which follows a poisson distribution. I have taken 5 data sets consisting of 30 counts each and l have used them in a chi squared gof test to see if they follow a poisson distribution. For each data set my p-value has been changing. Initially it was 0.5 then...
I have been working with a 2.8 (decayed over summer) micro curie cobalt-57 source testing a gamma camera. I would like to know if this made my risk for getting cancer higher ? My employers say l don't need to be worried.
So l am designing a radiation detector using solid state silicon photo multipliers. On their website they tell me that the SiPM must be coupled to a Cs(Ti) crystal with a combination of specular reflector diffuse reflector film between the scintillator and detector. How does a combination of a...
I am doing nuclear counting for medical imaging and l do not know the 'true' estimate of counts for my system. So to see if my system is operating consistently as l change a certain part, l am going to measure its precision. That is, as l change that part, are my number of counts within the same...
I calculated 15 absolute deviations and their mean absolute deviation. Would it be valid for me to say my data set is accurate if all the 15 absolute deviations are within ±5% of the mean absolute deviation ?
Hi Guys,
I am trying to measure variability in a part for my sensor which l do not know the true value. So l decided that a good way to measure variability in this case would be to measure precision of my data points as l change this part on the sensor. So l was wondering, can l compare the...
I am changing around parts on the sensor and l want to know if the performance stays the same as l change the parts. In other words, l take measurements on a sensor and then change let us say a transistor, and then take measurements again. I want to compare the data from before l removed the...
I just want to know if the data sets are equal, l know they have the same distribution, but l want to know if the difference in the two data sets are statistically significant or they are a cause of concern. Thanks for your insight.
So l am testing a sensor l recently developed. I am changing parts on the sensor and testing to see if my data is reproducible with different parts. I compare the data using the KS test. However, the data always have the same distribution or trend line. To test if the two data sets are the same...
So l have got 16 data points and l would like to know if this data follows a uniform distribution. I have tried using the punif function in R, but l am not sure about the results l am getting. Can someone please tell me what is the best way and hopefully easiest way to see if data is uniformly...
I have two sets of data, one represents electrical noise in a circuit and the other represents the gain in the circuit. So l varied the voltage in the circuit and calculated both the gain and the electrical noise at those voltages. Now l want to know what kind of analysis can l do to make sure...
They are 7 parts each with 5 measurements. I want to compare 7 sets of data at the end of the day, and see if they are the same.
Doesn't the t-test work in a situation you have a Gaussian distribution ?
This is exactly what l am looking for. After testing a part and replacing it with another l want to know if the mean distributions of the 7 parts are equal. In other words this tells me that changing the part on my camera doesn't affect its performance. Hopefully that is the conclusion l want to...
So l guess the variance is good enough. After adding up the variances l just end up calculating the standard deviation and l will use that as the error in my equipment.
How is percentage uncertainty different from standard deviation ? I have five measurements and l calculated the average, standard deviation and variance. Do l need to calculate the percentage uncertainty ? Does percentage uncertainty give me any more information which the other values l...
I will be measuring counts per pixel. So l want to know if the variance is due to random in nature, or it is due to something wrong with the part l am changing.
I am testing a certain part on a camera. So l was thinking of taking a set of measurements and then change that part and take another set of measurements.After having those two sets of data l wanted to do a chi-square test in order to see if variations in how the two parts perform is due to...
Is there a systematic way in which l can determine the behavior of this sequential circuit ? The textbook gives me its counting sequence but l don`t understand how they came to it
