Data Definition and 998 Threads

I just graduated, and one of my last classes in school was computational physics. We would write programs using C++ to simulate all sorts of physical situations, write a bunch of data to a text file, and then import that data into Mathematica, where we would use the data to create graphs...

I'm doing some work and don't really know if there is a better way to proceed. I have vendor information of how much premium they bring in, and how much losses they incur. With those 2 figures, I can get a 'loss ratio' of each vendor. My job is to look through the list and Identify any...

Homework Statement Explain and compare two efficient implementations of a priority queue using binary tree. Ilustrate this on an example of ascending priority queue that is created when elements 15, 38, 45, 21, 8, 55,20 are inserted and the two largest elements are deleted. Homework Equations...

I wasn't sure where to post this, but I figured this would be a topic under General Physics. I am aware that the next generation of observations, ranging from cosmological observations to post-LHC particle physics experiments, will produce overwhelmingly large and complex datasets, far larger...

I have a B.S. in physics, I am currently in a non-thesis Master of Engineering in Mechanical/Biomedical engineering and set to graduate in the spring.

Hi, How can one calculate background rejection from a background sample applying cuts ??

I am looking for some help, or even advice as how to proceed. I am trying to quantify an impulse from a hand (a high velocity low amplitude motion). In attempt to do that, I've tried attaching an accelerometer to my hand. My problem is, that the values I'd like to calculate as an objective...

I am requarid to submit reference letter with complite reference data (of my recomendator) could you tell me what dose reference data means? Is it just list of publications of something else? o_O

Any help would be much appreciated. The problem lies in the non-Gaussian distribution of the sample. If we take the entire data set of total fish catch, the skewness statistic equals 7.463 with a std. error of skewness of 0.39. Accordingly, the Z dist. (7.463/0.39)=19.14. Overall, the...

Homework Statement Okay so we're testing the effects different types and number of layers can have the heat released through conduction. in our results we found that the heat released was reduced by 50% for 2 layers compared to 1 layer and that the heat released was reduced to 34% for 3 layers...

What books of solved problems (free in pdf) would you recommend for data structures and algorithms in C (linked lists, trees, sorting and searching algorithms, graphs, recursion, files)? Note: I am not looking for theoretical books, but books of solved problems. Thanks for replies.

I didn't know where exactly should I post this kind of question :) I need to find experimental values of linear thermal expansion coefficients of copper at various temperatures (ranging 100-1500K); however, as much as I google it I only get coefficients at 20 degrees of celsius, or else there...

I hope this is the right place to post this, please move if you think it's needed. I want to ask how do I extrapolate a correlation from a bunch of numbers. I did and experiment on gyroscopes, and have three kinds of data, w1, w3 and F_t, the later two can be used to calculate L3 and T_g. My...

Hi everyone, I am looking for any available experimental data which models off-road vehicle travel in clay and measures tyre and soil parameters. Parameters I am looking for include pull, torque, shear strength of the soil, sinkage, slip and deflection. If anyone knows of any available raw data...

what I am wanting to know is what are the problems with sending data with photons of light? in detail? why have we not got this up and running. I want to know so I can work on some or one of the problems

I'm planning to start grad school for astrophysics next year, but am kind of put off by reading about the lack of jobs in science after graduation. It looks like data science is the current hot field to go into, even for PhDs in other fields. Would it make sense to start a PhD program fully...

HI all, I'm starting by senior research and I am in the hunt of some data! Specifically magnetometer data from an Earth orbiting satellite, I could get the data I think from the http://ppi.pds.nasa.gov/ site but was curious if anyone had an insight or guidance. At my college we have a...

Many may be familiar with the Libet experiments that suggested that the brain begins the process of preparing for a motor action before the subject decides to make the action. This has been discussed and argued over a great deal in the past several decades. I came across this in reading about...

Hi All, I am thinking of the issue of diminishing returns re linear regression. Can it be determined/decided from the data itself, or is it decided just from the context? I was thinking of examples like that of grade vs daily study hours or (height )jump length vs year ( winner heights have...

From my understanding of how SPI interface works, the clock basically sends out data when it is set to HIGH(or LOW). So, why does it seem like in pictures of the SPI lines, the setting of HIGH and LOW appears periodically. Can't we just put data onto DATA line, turn CLOCK line on to send, then...

A colleague and I were recently approached by a publisher of educational materials regarding licensing the data from our paper, "Studying the Internal Ballistics of a Combustion Driven Potato Cannon using High-speed Video". See: http://arxiv.org/ftp/arxiv/papers/1305/1305.0966.pdf This is...
