Consider a cold gas thruster rated at 1 lbf per firing. The thruster is on-off: there is no throttling, so when it fires it's at a constant full thrust. Assume the gas is nitrogen, and that it has a specific impulse of 72 s. The thrust force per firing ($F_\texttt{th}$) is the product of mass flo...

This is the objective function of a variational autoencoder. I am not sure how to interpret the second term. It appears to be an expectation value over log p(x^(i)|z), but I'm not sure what role the subscript q(z|x^(i)) plays here. Thanks in advance.

I want to develop a quality water IoT system. The picture below shows the idea. I'm not sure the device that I have to use for this project. My idea is: Every X minutes (I'm not sure the time) get information from the sensors. Run some machine learning algorithms and/or deep learning algorithms...

Is there a possible way to implement sort of helper struct using C++14 which takes as a template argument a Number, return type Ret and input type T and would contain a member type std::function<Ret(T...)> where sizeof...(T) == Number?

I have been working on testing whether same encrypted files are same without decrypting it. I have a test file provided to me one with normal data and another encrypted version of it. I need to check whether that test file(without encryption) which goes through an api and encrypts it will be the ...

Specifically for spells such as Dispel Magic, Restore Senses, Remove Disease, or Remove Curse, when you roll your Counteract check using your relevant skill modifier or other appropriate modifier to your check against the target’s DC. [...] the counteract check modifier is your spellcasting abil...

I've been accepted in a research internship. However, after I sent an email to my supervisor asking about some details, he told me that he has no idea about who I am, and that maybe I've been exchanging with someone else. But the confirmation letter was signed by him. I'm so confused, I'm afraid ...

An attacker want's access to a specific account, he doesn't know the password. It's a high entropy password. +128bits The attacker has the hash for the password (Assuming OWASP suggested bcrypt with cost 12) The attacker has a list with n hashes that HE KNOWS are hashes for the same password he ...

[This is a question motivated by theoretical physics, so apologies if the language is rough...] In three dimensions the spaces of invariant (or isotropic) tensors of rank $n$ have dimensions 1, 0, 1, 1, 3, 6, 15, 36, 91, 232, ... (see MathWorld). Equivalently, this is the number of trivial repres...

When someone writes to me while I am online during the weekend (a student or a colleague), is it impolite to not reply back, especially when they can see that I am online (on Mattermost for example or on any other app ...), although I reply back first thing Monday morning? Edit: First of all, tha...

Can using bash's globstar (**) operator cause an out of memory error? Consider something like: for f in /**/*; do printf '%s\n' "$f"; done When ** is being used to generate an enormous list of files, assuming the list is too large to fit in memory, will bash crash or does it have a mechanism to ...

I'm working on a project where I'll need to establish a connection between two HC-05 modules, each connected to an Arduino, but for now I'm just trying to get one to work and connect to my phone, but I'm not sure if I'm doing anything right... I'm not able to give AT-Commands, and as a result the...

One of the most regularly measured phenotypes in bacterial synthetic biology is growth. Anyone who does wet lab microbiology or synthetic biology will have performed a growth curve measurement. However, it is quite rare in synthetic biology papers for growth to be characterised using a mathematic...

Is there anywhere in the scripture where HaShem says "I love you." or "I love"? Directly and not indirectly.

I am exploring the theoretical character differences between an optimist, pessimist and an idealist. Originally I had thought that an idealist would really sit in the middle of the other two, but now I'm second guessing myself. I am basically looking for a noun of a person that tries to make thin...

I have an xyz file upon which after processing in a python, I determine bonds between different atoms. What would be the correct filetype that I can write to visualize this bond information in VMD?

I want 2 aligned environments to sit side by side. I tried tikZ package for that (because I know only that, I am a beginner.) Here's what I tried: \documentclass{article} \usepackage{tikz, mathtools} \begin{document} \begin{tikzpicture} \node at (0, 0) {\begin{align*} x^2 - y^2 = (x + y) (x - ...

I'm thinking of a little something where a hundred Sun-sized stars would dot the sky (night or day; the Sun just blocks other stars at day after all). These stars are scattered across the sky, but they are all exactly half a light year away from Earth. So what would the sky look like in this scen...

I can certainly imagine one of the symptoms could potentially be engine fuel starvation. If the fuel flow to the engine isn't totally blocked, how can one recognize a clogged fuel filter?

We recently had issues with people messing around inside our system. To prevent code injections within my python code, I implemented the following if block: #! /usr/bin/python3 #-*- coding:utf-8 -*- def main(): print("Your interactive Python shell!") text = input('>>> ') for keyword i...

At what age should I expose my child to coding in order to see if they like it? Some argue that 5-6 years old is a good age to start coding (1, 2, 3, 4, 5, 6). I am looking for answers based on personal experience or on research, rather than opinion-based answers. RELATED: What are some milestone...

An electrician ran some new wires and had to bore through the floor joists. In doing so, one came very close to a knot in the wood. The floor above squeaks now as a result, where it didn't before. This is probably just a minor annoyance but I'd like to fix it if possible. What options do I have, ...

I'm interested in acquiring a specific Feat more quickly that just from levelling. (If it's relevant it's a Mastery Feat for the weapon I've just portentously received and am proficient with, but would like to become excellent with) I know that you can gain proficiencies in entire weapons classes...

On page 201 of Farb and Margalit's Primer on Mapping Class Groups, they explain why the mapping class group $\mathrm{Mod}(S)$ is torsion-free when $\partial S \neq \varnothing$. Here is my understanding of the argument: Let $S$ be a surface with a hyperbolic metric and let $\phi\colon S \to S$ be...

Let $G$ be a finitely generated torsion-free nilpotent group. The Malcev completion of $G$ is a nilpotent Lie group $N$ into which $G$ embeds as a lattice. One way to construct this is to take the completion $\widehat{\mathbb{R}[G]}$ of the real group ring with respect to the augmentation ideal...

I connect to remote Linux servers using SSH via PuTTY terminal emulator. I notice the commands I run and the output on console keep appending in the terminal window. I mean, when I use scrollbar and scroll up/down, I can see the previous commands I have run and their output, like on a printed pap...

On the one hand, they appear to be equal: 26 For you are all sons and daughters of God through faith in Christ Jesus. 27 For all of you who were baptized into Christ have clothed yourselves with Christ. 28 There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor...

If we want to put an array in the caption of some table environment, we cannot do this (which causes an error) \caption{A matrix here: $\begin{array}{lr} a & b \\ c & d \end{array}$} Instead, we can put an array in the caption of some table environment as \caption[]{A matrix here: $\begin{array}...

So, my setting is a small border town on the edge of the [x] empire- beyond the town is the Eastern Reaches and is mostly unexplored. The border has been explored up to around 60 miles by the feudal lord mentioned below- just plains and forests, no iron of any note beyond the small vein close to ...

Per the artificer rules... If the item requires attunement, you can attune yourself to it the instant you infuse the item. Okay. Nice. Great. Except... how does it work when the item is given to another character? Let's picture these scenarios: Scenario one. My artificer has created an Resistan...

I was trying to write Fizz Buzz and I came across an unexpected interaction. If I do std::cout << i, it automatically converts i (int) into a string and prints it? But if assign i to a string variable, it prints a blank instead? I managed to solve it by using std::to_string, but I was just wonder...

I am going to make this code below into the second release of my library, but I want to make sure I haven't missed anything. If there are improvements that can be made, I'd like to implement them. This code is also on GitHub. import random import secrets import string import urllib.request class...

I'm a little uncomfortable with the graph of a taxonomy. I never used tikZ or Forest and found it very difficult to understand in a short time. I have to draw the taxonomy graph that follows. Can anyone please help me in this diagram with the latex code? I'm going to be very appreciative. Thank y...

In the US, if a defendant in a criminal trial (in state court) wants to change the venue of the trial, is it possible to have it changed to another state?

I am creating a social media website for gardeners. One of the features is that gardeners can create their own garden journals. A user can indicate in the garden journal where he or she is growing the plants that are the subject of the garden journal. For instance the location could be the balcon...

Can the Replicator from Star Trek: TNG create illicit substances? Say there was a life form that lived on cocaine or THC or required them for recreational purposes, could the Replicator make these? Or are there specific Starfleet Regulations and specifications that make it impossible as they are ...

I remember reading a sci-fi book decades ago which had large scale space battles. One side utilised the power of a sun as a weapon. I recall that the sun dimmed (similar to the latest Star Wars films) as the weapon was used against a fleet of spaceships.

In Final Fantasy 7 (the original), Shinra says that they plan to stop the Meteor by loading a rocket with Huge Materia, and sending it to blow up the Meteor. The next section of the game is going to different locations to steal the Huge Materia before Shinra can get/use it, ending with you steali...

What is the meaning of もの in that sentence 真相を知るものは誰もいません Dictionary says it can mean 'thing', but also 'really'. I guess thus it's 'really' but when I automatically translate this sentence, the meaning 'really' never appears.

I'm working on a blogging platform which have a community of writers. In the first iteration, I paired a monospace font with a serif font for the entire platform because those two fonts are most preferred by writers. They love the typewriter feeling. However, multiple sources shows monospace font...
