1. ### Magnetic field of an infinite current sheet : Amperes law

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.
2. ### Integration techniques

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.
3. ### What distribution is this

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
4. ### How much variance in my p-value

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...
5. ### Will 2.8 micro curie of radiation cause cancer

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.
6. ### Using a combination of a specular and diffuse reflector

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...
7. ### Comparing Absolute Deviation to Mean Absolute Deviation

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...
8. ### Comparing Absolute Deviation to Mean Absolute Deviation

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 ?
9. ### Comparing Absolute Deviation to 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...
10. ### Kolmogorov-Smirnov and P-value

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...
11. ### Kolmogorov-Smirnov and P-value

Yes, it is the same. The data is generated from a radioactive source which is constant. The parameter of the distribution is one.
12. ### Kolmogorov-Smirnov and P-value

I am measuring the # of counts in a sensor that is being hit by a light source which follows the Poisson distribution in the variations
13. ### Kolmogorov-Smirnov and P-value

So what is the best way to answer my question as to are the two data sets equal.
14. ### Kolmogorov-Smirnov and P-value

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.
15. ### Kolmogorov-Smirnov and P-value

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...
