The Intertec Superbrain is an early personal computer that was developed in the early 1980s. It is notable for its unique design, which included a built-in monitor and a modular architecture that allowed users to expand the system's capabilities. The Superbrain was based on the Zilog Z80 microprocessor and was compatible with CP/M, an operating system widely used during that era for personal computers.
Cryptography is a crucial technology that provides security for data and communications, enabling various applications across multiple fields. Here are some key applications of cryptography: 1. **Secure Communications**: - **Email Encryption**: Tools like PGP (Pretty Good Privacy) and S/MIME are used to secure email content against unauthorized access. - **Messaging Apps**: Applications like Signal and WhatsApp use end-to-end encryption to protect user conversations.
The "hard problem of consciousness" is a term coined by philosopher David Chalmers in the 1990s to highlight the philosophical and scientific challenge of explaining how and why we have subjective experiences, or qualia. While the "easy problems" of consciousness involve understanding the mechanisms and functions of the brain that correlate with behaviors and cognitive functions (such as perception, attention, and memory), the hard problem focuses on the nature of conscious experience itself.
An acoustic harassment device, often referred to as a Long Range Acoustic Device (LRAD), is a type of sound system designed to emit high-decibel sound waves over long distances. These devices are typically used for crowd control, deterrence, and communication in situations such as protests, riots, and military operations.
An acoustic metric typically refers to a quantitative measurement used to assess the characteristics of sound or acoustics in various contexts. While the term can be employed in several domains, including environmental acoustics, audio engineering, and speech analysis, its specifics can vary based on the application.
Acoustic quieting refers to techniques and technologies that reduce or minimize unwanted sound or noise, particularly in environments where noise control is essential. This concept is widely applicable in various fields, including engineering, architecture, and audio production. In engineering and military applications, especially in the design of submarines, aircraft, and other vehicles, acoustic quieting involves reducing the noise they produce to avoid detection.
The acoustic wave equation is a partial differential equation that describes the propagation of sound waves through a medium, such as air, water, or solids. It is derived from the principles of fluid dynamics and elasticity, reflecting how pressure changes propagate through a compressible medium.
Cryptographic primitives are the basic building blocks used in cryptographic protocols and schemes to provide security services such as confidentiality, integrity, authenticity, and non-repudiation. These primitives are essential components that can be combined in various ways to create more complex cryptographic systems. Here are some of the fundamental types of cryptographic primitives: 1. **Symmetric Key Cryptography**: This involves algorithms that use the same key for both encryption and decryption.
Cryptography law refers to the legal and regulatory frameworks that govern the use, distribution, and implementation of cryptographic technologies and systems. These laws address a variety of issues, including but not limited to: 1. **Regulation of Cryptographic Technologies**: Many countries have regulations that govern the use of encryption technologies, particularly regarding export restrictions on cryptographic tools which could be used for purposes that threaten national security.
Nonsense refers to language or ideas that do not have a clear meaning or that lack logical coherence. It can be used to describe statements, writing, or speech that are absurd, illogical, or devoid of sense. Nonsense can serve various purposes, including humor, artistic expression, or social commentary.
As of my last update, there is no widely recognized figure or prominent public entity known as "Ivan Bizjak." It is possible that he may be a private individual or a person of local significance who has not gained international recognition. If Ivan Bizjak has become notable after October 2023 or is a context-specific figure in a particular field (such as sports, art, or academia), I wouldn't have information on that.
As of my last knowledge update in October 2023, there is no widely recognized figure or entity named Charles Hellaby that appears in historical, literary, or notable current events contexts. It's possible that Charles Hellaby could refer to a private individual or a less well-known subject.
Mamokgethi Phakeng is a prominent South African academic and administrator recognized for her contributions to higher education, particularly in the fields of mathematics education and university leadership. She has served as the Vice-Chancellor of the University of Cape Town (UCT), making her the first black woman to hold this position in the university's history. Known for her advocacy of diversity and inclusion within academia, Phakeng has been influential in promoting access to quality education for underrepresented groups in South Africa.
Alexander Novikov is a prominent Russian mathematician known for his contributions to topology, differential geometry, and mathematical physics. Born on April 3, 1935, he has made significant advancements in various fields, particularly in the area of geometric topology and the theory of manifolds. Novikov is particularly known for developing the Novikov conjecture, which relates to the signature and surgery theory in topology.
Alexey Ivakhnenko is a prominent Russian scientist and engineer known for his significant contributions to the fields of cybernetics, artificial intelligence, and systems theory. He is particularly recognized for developing the "Ivakhnenko polynomial" approach and for his work on "group method of data handling" (GMDH), a method that combines modeling and learning algorithms for data analysis and prediction.
Anatoly Libgober is a mathematician known for his work in the fields of algebraic geometry and topology. He has made significant contributions to various areas, including the study of algebraic curves, singularities, and the theory of algebraic varieties. Libgober has also been involved in research related to the topology of algebraic varieties and their geometric properties. He has published numerous papers and has been involved in teaching and mentoring students in mathematics.
As of my last knowledge update in October 2021, there is no widely recognized person or entity named Anry Nersessian. It’s possible that this name could refer to a private individual, a lesser-known figure, or an emerging personality in various fields.
Boris Bukreev is likely a misspelling or confusion with the name of Anatoli Boukreev, a notable Russian-born mountaineer. Anatoli Boukreev is known for his significant contributions to high-altitude climbing, particularly in the Himalayas. He gained attention for his role during the 1996 Mount Everest disaster, where he assisted in rescuing climbers during severe weather conditions.
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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
