Hyperspectral imaging is a technology that captures and processes information from across the electromagnetic spectrum. Unlike traditional imaging, which uses just a few bands of light (such as red, green, and blue), hyperspectral imaging collects data in many narrow bands, often hundreds or even thousands of them, across the visible, near-infrared, and sometimes even into the thermal infrared ranges.
Nicușor Dan is a Romanian politician, mathematician, and civil society activist who became known for his involvement in local politics and his efforts to improve urban governance in Bucharest, the capital of Romania. He was born on December 24, 1970, in the city of Făgăraș. Dan is a founding member of the Save Romania Union (USR), a political party formed to address issues of transparency, anti-corruption, and civic engagement in Romania.
In heraldry, a sun is a common symbol often depicted as a radiant, circular figure. It can have various designs, including a simple disk or a more elaborate representation featuring rays emanating from it. The sun typically symbolizes glory, divinity, and enlightenment. When used in coats of arms or other heraldic devices, the sun can represent different concepts depending on its design and context.
CalCOFI, which stands for the California Cooperative Oceanic Fisheries Investigations, is a research program established in 1949 that focuses on the marine environment off the coast of California. It is a collaborative effort involving various agencies, including the California Department of Fish and Wildlife, NOAA's National Marine Fisheries Service, and academic institutions.
The benthic zone is the ecological region at the lowest level of a body of water, including oceans, seas, and lakes. This zone encompasses the sediment surface and sub-surface layers, extending from the shoreline down to the deep-sea floor. The benthic zone is characterized by its unique habitat, which includes various types of substrate, such as sand, mud, and rock.
In oceanography, a "knoll" refers to a small hill or mound that rises from the seafloor. These underwater features can vary in size and are often found on the continental shelf or in ocean basins. Knolls are typically formed by geological processes such as volcanic activity, sediment deposition, or tectonic movements. They can serve as important habitats for marine life, providing structure and substrate for various organisms. Additionally, knolls can influence ocean currents and contribute to local ecosystems.
Goodyear MPP (Managed Pressure Performance) is a technology and service offering designed to improve drilling performance and optimize wellbore stability in the oil and gas industry. This approach allows operators to manage the pressure in the wellbore more effectively during drilling operations, reducing the risks associated with various drilling challenges such as blowouts, fluid loss, and wellbore instability. The Goodyear MPP system typically involves real-time monitoring and control of the pressure profile in the wellbore.
The Normalized Difference Water Index (NDWI) is a remote sensing index used primarily to assess the presence and distribution of water bodies. It helps distinguish between water and non-water features in satellite imagery. The NDWI exploits the reflective properties of water in different parts of the electromagnetic spectrum, particularly focusing on the visible (green) and near-infrared (NIR) wavelengths.
Sea ice concentration refers to the fraction of a given area of ocean surface that is covered by sea ice. It is typically expressed as a percentage, ranging from 0% (no ice) to 100% (entire area covered with ice). This measure is crucial for understanding the extent of sea ice in polar regions and its changes over time, which can be indicative of climate change and its effects on the environment.
The Glogauer Liederbuch is a significant collection of medieval German songs, specifically from the 15th century. It is named after the town of Glogau (now Głogów in Poland), where it is believed to have been compiled. The manuscript contains a variety of musical forms, including secular songs, religious hymns, and folk tunes, often notated in a way that reflects the musical practices of its time.
The Trent Codices, also known as the Codices of Trent, refer to a collection of ancient manuscripts that were discovered in the city of Trento, Italy. These codices date from the medieval period and are notable for their historical, cultural, and artistic significance. The collection typically encompasses various texts, including religious, liturgical, and perhaps legal contents, which provide insights into the social and cultural life of the time when they were written.
Self-cleaning glass is a type of glass that has been specially treated to reduce the accumulation of dirt and grime, making it easier to keep clean. This technology typically utilizes a combination of hydrophilic and photocatalytic properties. 1. **Hydrophilic Coating**: The surface of self-cleaning glass is coated with a hydrophilic substance, which means it has an affinity for water.
The Sunlight League is a term that has been used in various contexts, but the most common reference appears to be related to grassroots advocacy and civic engagement initiatives focused on government transparency, accessibility, and accountability. Organizations or movements associated with the name typically aim to promote open government practices, reduce corruption, and ensure that citizens have a voice in democratic processes.
A "global city," also known as a world city or alpha city, is a significant urban center that plays a crucial role in global economic, political, and cultural systems. These cities are characterized by their influence and connectivity beyond national borders, serving as hubs for international finance, trade, culture, and innovation.
The Ibrahim Index of African Governance (IIAG) is a comprehensive tool designed to measure and assess the quality of governance in African countries. Launched in 2007 by the Mo Ibrahim Foundation, the index aims to promote good governance and accountability across the continent by providing an objective framework for analysis and comparison.
The Index of Dissimilarity (ID) is a statistical measure used in social sciences to quantify the level of segregation or diversity within a population. It specifically measures how evenly two or more groups are distributed across geographical areas or social contexts.
The Kardashian Index (KI) is a humorous, informal metric that was introduced to describe the discrepancy between the popularity of a person and their academic or professional credentials. Named after celebrity Kim Kardashian, the index is often used in the context of academia and science to highlight cases where individuals with significant social media followings or public personas have relatively low academic impact, as measured by metrics such as citation counts or publication records.
A Loeb space is a mathematical construct that arises in nonstandard analysis, a branch of mathematics that extends the traditional framework of mathematical analysis. Specifically, Loeb spaces are used in the context of integrating functions and dealing with nonstandard measures. The concept is named after the mathematician Daniel Loeb, who introduced a method for constructing a "Loeb measure" using ultrafilters.
