The Naval Hydrographic and Oceanographic Service typically refers to an organization within a country's navy that is responsible for collecting, analyzing, and disseminating hydrographic and oceanographic data. This service plays a crucial role in supporting naval operations, maritime safety, navigation, and environmental protection. Key functions of such a service may include: 1. **Hydrographic Surveys**: Conducting detailed surveys of oceans, seas, rivers, and lakes to produce nautical charts that provide essential information for safe navigation.
Negation as failure is a concept primarily used in logic programming and non-monotonic reasoning, notably in the field of artificial intelligence and computational logic. It is a way of handling negation in a way that is consistent with the principle of closed world assumption (CWA). In classical logic, a statement can either be true or false, and the truth of a statement can be proven with evidence. However, in many practical applications, we often deal with incomplete knowledge about a system or domain.
Negative feedback by Wikipedia Bot 0
Negative feedback is a regulatory mechanism in which a system responds to a change by initiating processes that counteract that change, ultimately bringing the system back to its desired state or equilibrium. This concept is commonly found in various fields, including biology, engineering, and systems theory. In biological systems, for example, negative feedback helps maintain homeostasis. An example is the regulation of blood sugar levels: when blood sugar rises after eating, the pancreas releases insulin, which helps lower blood sugar levels.
Neo-bulk cargo by Wikipedia Bot 0
Neo-bulk cargo refers to a category of cargo that is not classified as traditional bulk cargo (like liquids, grains, or ores) or general cargo (packed goods). Instead, neo-bulk cargo consists of items that are shipped in large quantities and are typically handled individually or in units. This category often includes goods that are not packed in containers but are shipped in bulk, yet still retain some characteristics of both bulk and general cargo.
Neo-Piagetian theories of cognitive development build upon the foundational work of Jean Piaget, who proposed that children progress through a series of distinct stages of cognitive development. However, Neo-Piagetian theorists aim to address some limitations and gaps in Piaget's original theories by integrating insights from cognitive psychology and developmental neuroscience.
A **Network Probability Matrix** (NPM) is a mathematical representation often used in network analysis to describe the probabilities of transitions or interactions between nodes in a network. It is typically employed in various fields such as graph theory, social network analysis, systems biology, and more. Here are some key points to understand about it: ### Structure 1.
Newman's lemma by Wikipedia Bot 0
Newman's lemma is a result in the area of mathematical logic, particularly in the field of set theory and model theory. It relates to the concept of elementary embeddings and the properties of models of set theory.
Newton–Wigner localization is a concept in quantum mechanics that deals with the localization of quantum particles, especially in the context of relativistic quantum field theories. It was introduced by the physicists T.D. Newton and E.P. Wigner in the 1940s as a way to define the position of relativistic particles. In non-relativistic quantum mechanics, the position of a particle can be represented by the position operator in a straightforward manner.
NGC 6820 and NGC 6823 are two astronomical objects located in the constellation Vulpecula. They are closely associated with each other, as NGC 6823 is an open cluster of stars, and NGC 6820 is a surrounding nebula, a region of gas and dust that is often linked to the processes of star formation.
Niagara Whirlpool by Wikipedia Bot 0
The Niagara Whirlpool, also known as the Niagara River Whirlpool, is a natural whirlpool located along the Niagara River, just downstream from Niagara Falls, straddling the border between the United States and Canada. It is formed as the river flows through a series of steep cliffs and a deep gorge, leading to a large circular pool where the river's current creates a powerful swirling motion.
Nikephoros Chrysoberges, often known simply as "Chrysoberges," was a Byzantine official and nobleman who lived during the 11th century. His name means "Golden Berg," with "Chrysos" meaning "gold" in Greek and "berg" coming from the Germanic word for "mountain" or "hill." However, details about his life and contributions may vary depending on the specific historical context and the focus of sources discussing him.

Noise measurement by Wikipedia Bot 0
Noise measurement refers to the quantification and analysis of unwanted or disruptive sound in various environments. It is crucial in fields such as acoustics, environmental monitoring, industrial safety, and urban planning. Noise can adversely affect human health, communication, and quality of life, so measuring it accurately is essential for mitigation and compliance with regulations. ### Key Concepts in Noise Measurement: 1. **Decibel (dB)**: The primary unit used to measure sound intensity.
A no-reserve auction is a type of auction where the item being sold does not have a minimum reserve price that must be met for the item to be sold. In other words, regardless of the final bid amount, the item will be sold to the highest bidder at the end of the auction, even if that amount is lower than what the seller might have preferred.
Nominative-accusative alignment is a type of morphosyntactic alignment found in many languages, particularly in Indo-European languages. In systems with nominative-accusative alignment, the subject of an intransitive verb (a verb that does not take a direct object) is treated the same way as the subject of a transitive verb (a verb that does take a direct object).

Pinned article: ourbigbook/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.
