Generic point 1970-01-01
In topology, a **generic point** is a concept used to describe a point that represents a subset of a topological space in a broad or "generic" sense. Specifically, a point \( x \) in a topological space \( X \) is called a generic point of a subset \( A \) of \( X \) if every open set containing \( x \) intersects \( A \) in a non-empty set.
Local property 1970-01-01
The term "local property" can refer to different concepts depending on the context in which it is used. Here are a few interpretations of "local property": 1. **Real Estate Context**: In real estate, local property may refer to real estate assets that are situated in a specific geographic area. This can involve considerations like property value, market trends, zoning laws, and community characteristics that pertain to that specific locality.
Surveying instruments 1970-01-01
Surveying instruments are tools and devices used by surveyors and engineers to measure distances, angles, and elevations, as well as to map and analyze land and structures. These instruments are crucial for establishing precise measurements to ensure accuracy in construction, land development, and various types of civil engineering projects. Here are some common types of surveying instruments: 1. **Theodolite**: A precision instrument for measuring horizontal and vertical angles.
Asian Association on Remote Sensing 1970-01-01
The Asian Association on Remote Sensing (AARS) is an international organization that focuses on the promotion and advancement of remote sensing technologies and applications in Asia. Established to facilitate the exchange of knowledge and expertise among countries in the region, AARS plays a key role in fostering collaboration among researchers, institutions, and organizations engaged in remote sensing activities.
Cavendish experiment 1970-01-01
The Cavendish experiment, conducted by British scientist Henry Cavendish in 1797-1798, was a groundbreaking experiment that measured the force of gravitational attraction between masses. The primary aim of the experiment was to determine the density of the Earth, but it also yielded the first accurate measurement of the gravitational constant (G), which is fundamental to our understanding of gravitational interactions.
Day length fluctuations 1970-01-01
Day length fluctuations refer to the variations in the duration of daylight experienced over the course of the year due to the tilt of the Earth's axis and its orbit around the Sun. This phenomenon is most noticeable at higher latitudes, where the difference between the longest and shortest days can be significant, particularly during the summer and winter solstices. The key factors contributing to day length fluctuations include: 1. **Tilt of Earth's Axis**: The Earth is tilted at an angle of approximately 23.
A New Era of Thought 1970-01-01
"A New Era of Thought" is not a widely recognized term or title, so its meaning could vary based on context. It may refer to various concepts, including: 1. **Philosophical Movements**: It could denote a shift in philosophical thinking, reflecting new ideas or paradigms that challenge or expand upon established theories.
Judy A. Holdener 1970-01-01
Judy A. Holdener is a mathematician known for her work in topology and mathematical education. She has contributed to both research and teaching, focusing on areas such as algebraic topology, and has been active in promoting mathematics at various educational levels. In addition to her research, Holdener has also been involved in outreach efforts to increase the engagement and participation of underrepresented groups in mathematics.
Jaffard ring 1970-01-01
A Jaffard ring is a concept in the field of functional analysis and operator theory, named after the mathematician Claude Jaffard. It is related to the study of certain types of algebras of operators, particularly those exhibiting specific algebraic and topological properties.
Growth rate (group theory) 1970-01-01
In the context of group theory, the growth rate refers to a concept that assesses how the number of elements in the finite index subgroups of a group grows with respect to their index. More specifically, the growth rate can describe how the size of the balls in the Cayley graph of a group increases as the radius of the ball grows, which is tied to the group’s algebraic structure and properties.
Jérôme Franel 1970-01-01
Jérôme Franel is a name that may refer to different individuals or concepts depending on the context. However, without additional context, it’s difficult to provide a specific or detailed answer. If you are looking for information about a person named Jérôme Franel, it would help to know more about their background or field (e.g., arts, sciences, literature) or any specific aspect you're interested in. Please provide more details!
Computer-related introductions in 1967 1970-01-01
Metrizable space 1970-01-01
Nodec space 1970-01-01
It seems there might be a typographical error in your query. If you meant "Node space," "NOC space," or "Nodec Space" in a specific context (like computer networking, mathematics, or some other field), please clarify. As of my last training data, there isn't a widely recognized concept specifically named "Nodec space.
Nowhere dense set 1970-01-01
Bessel ellipsoid 1970-01-01
The Bessel ellipsoid refers to a specific mathematical model of the Earth's shape, which is used in geodesy and cartography. Named after the German mathematician and astronomer Friedrich Bessel, the Bessel ellipsoid is an oblate spheroid that approximates the shape of the Earth, particularly in relation to the geodetic surveys of the 19th century.
Double summit 1970-01-01
"Double summit" can refer to different things depending on the context. Here are a few possible interpretations: 1. **Geographical Term**: In mountaineering, a "double summit" might refer to a mountain that has two prominent peaks or summits. Climbers may refer to the challenges of reaching both peaks.
ED50 1970-01-01
ED50, or the "effective dose 50," is a term commonly used in pharmacology and toxicology to describe the dose of a drug or substance that produces a therapeutic effect in 50% of a population or experimental subjects. It is a key measure in assessing the efficacy of a drug and helps to understand its potency and the dose-response relationship.
Geographical pole 1970-01-01
The term "geographical pole" refers to the two points on the Earth's surface where its axis of rotation intersects the surface. These points are known as the North Pole and the South Pole. 1. **North Pole**: Located at 90 degrees north latitude, the North Pole is the northernmost point on Earth. It lies in the Arctic Ocean and is covered by sea ice for much of the year.
Geopositioning 1970-01-01
Geopositioning refers to the process of determining the geographical position of an object or person in relation to the Earth’s surface. This can involve using various technologies and methods to pinpoint the coordinates (latitude, longitude, and sometimes altitude) of a particular location. Geopositioning is widely used in fields such as navigation, mapping, spatial analysis, environmental monitoring, and personal location services.
