hey all, i'm now trying to create a queue sort of system for actions that an object in my engine can use. basically it should take a function pointer and a list of the variables that should be passed when the function is called. i've had another method half working but ... | |

Invariants of the Riemann tensor for class $$B$$ warped product space-times. (English) Zbl 1002.83503
Summary: We use the computer algebra system GRTensorII to examine invariants polynomial in the Riemann tensor for class $$B$$ warped product space-times - those which can ... | |
# Is this formula logically valid
Is: $\exists x (P(x) \land Q(x)) \rightarrow \exists x P(x) \land \exists x Q(x)$ logically valid?.
I cant found an intepretation in wich the formula is false.
• Yes, it is logically valid. The opposite implication is not logically valid. – André Nicolas Jun 29 '13 at 4:47
Yes, ind... | |

# Normal Probabilities Using the Z-Table
Any normal distribution, which is completely described by the values of its mean, ${\displaystyle \mu }$, and its standard deviation, ${\displaystyle \sigma }$, can be transformed into the so-called standard normal via the transformation

# Detect static in audio with Python
I have a program running in python. It samples the demodulated FM output from an SDR. When there is no transmission, the input to the program is completely static.
How can I go about squelching the audio in a way like CSQ on a radio?
Here is what I have so far:

# Theories that predict the number of space-time dimensions
My impression in that most theories assume three spatial dimensions and one temporal dimension, though could in principle be formulated in others numbers of dimensions without inconsistencies. I know, however, that string theory makes specific predictions for... | |
# Two independent optional arguments for new commands

# Coherence and calibration
I am trying to find good definitions and examples for both these concepts regarding frequentist vs Bayesian statistics. Can anyone please shed light on them and explain them? Furthermore, why are Bayesian methods often considered coherent, while frequentist methods seem to focus on calibrat... | |
# Working with HPC clusters
In my university, we have an HPC computing cluster. I use the cluster to train classifiers and so on. So, usually, to send a job to the cluster, (e.g. python scikit-learn script), I need to write a Bash script that contains (among others) a command like qsub script.py.
However, I find this... | |
# Parsing and Recombining Inputs¶
In the chapter on Grammars, we discussed how grammars can be used to represent various languages. We also saw how grammars can be used to generate strings of the corresponding language. Grammars can also perform the reverse. That is, given a string, one can decompose the string into i... | |
