As of my last knowledge update in October 2023, there is no widely recognized definition or concept known as "Pasotron." It is possible that it refers to a specific product, service, software, or concept that has emerged after that date, or it might be a less-known term in a specific field or industry.
Surface freezing refers to the process where a liquid, usually water, forms a solid layer of ice at its surface while remaining in a liquid state below. This phenomenon can occur under specific atmospheric conditions, typically when temperatures drop, allowing the uppermost layer of a liquid body to freeze while the deeper layers remain unfrozen due to thermal insulation or the heat retained by the water.
Phase distortion refers to a phenomenon that occurs when different frequency components of a signal are shifted in phase relative to each other, leading to a change in the signal's waveform. This can happen in various contexts, including in audio processing, telecommunications, and signal transmission. In audio synthesis, for example, phase distortion is often used as a method for generating complex sounds by modifying the phase of a waveform, rather than directly altering its amplitude.
Specific potential energy is a measure of potential energy per unit mass of an object or a fluid. It quantifies how much potential energy an object has relative to its mass, allowing for comparisons between different objects or systems independent of their size or mass.
A Stoneley wave is a type of wave that propagates along the interface between two different media, particularly in solid materials. It is named after the British physicist William Stoneley, who studied such waves in the context of elastic wave propagation. Stoneley waves typically occur at the boundary between two solid materials, such as rock and fluid, or two different elastic solids. These waves are characterized by their ability to travel along the interface while decaying in the direction perpendicular to it.
"Streaming vibration current" is not a commonly used term or concept in established scientific literature or engineering practices, which may cause confusion. However, the term could potentially refer to a few related ideas in the context of fluid dynamics and vibration. 1. **Streaming Currents**: In fluid mechanics, "streaming" refers to the steady flow of fluid caused by a vibrating object, such as a vibrating membrane or surface. This phenomenon is often observed in acoustic streaming, where sound waves create fluid motion.
In number theory, the term "symbol" can refer to several different concepts depending on the context. Here are a few interpretations: 1. **Mathematical Symbols**: In a general sense, symbols in number theory (and mathematics in general) are used to represent numbers, operations, and relations.
The Ξ function, also known as the "Xi" function, is a mathematical function that is closely related to the Riemann zeta function. Specifically, it is defined in terms of the Riemann zeta function and has significance in number theory and the study of prime numbers.
Algebraic graph theory is a branch of mathematics that studies graphs through algebraic methods and concepts. It combines ideas from both graph theory, which is the study of graphs—objects consisting of vertices (or nodes) connected by edges—and various areas of algebra, particularly linear algebra and group theory.
"Bad control" can refer to several concepts depending on the context in which it is used. Here are a few interpretations: 1. **Management and Leadership**: In organizational behavior, "bad control" may refer to ineffective management practices that lead to poor employee performance, low morale, or an unhealthy workplace culture. This might involve micromanagement, lack of clear communication, or failure to provide adequate support and resources.
The term "compound of tetrahedra" refers to a specific geometric configuration that is formed by combining multiple tetrahedra in a particular arrangement. A tetrahedron is a polyhedron with four triangular faces, and it is one of the simplest three-dimensional shapes.
Advantages of fog: there is only one, reusing hardware that would be otherwise idle.
Disadvantages:
  • in cloud, you can put your datacenter on the location with the cheapest possible power. On fog you can't.
  • on fog there is some waste due to network communication.
  • you will likely optimize code less well because you might be targeting a wide array of different types of hardware, so more power (and time) wastage. Furthermore, some of the hardware used will not not be optimal for the task, e.g. CPU instead of GPU.
All of this makes Ciro Santilli doubtful if it wouldn't be more efficient for volunteers simply to donate money rather than inefficient power usage.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
