Established in 1878, it is one of the oldest mathematical journals in the United States. The journal is known for its high-quality publications and has contributed significantly to the advancement of mathematical knowledge over the years. AJM features original research papers, survey articles, and occasional contributions in areas such as pure mathematics, applied mathematics, and mathematical education.

"Annales de Gergonne" is a mathematical journal that was founded in the early 19th century by the French mathematician Joseph Gergonne. The journal is notable for its focus on geometry and mathematical topics and is considered one of the earliest specialized journals in mathematics. It published original research papers, problem sets, and discussions related to various aspects of mathematics, particularly geometry.

"Archiv der Mathematik" is a mathematical journal that publishes research articles in all areas of pure and applied mathematics. Established in 1949, it is known for its high standards of publication and peer review. The journal aims to facilitate the dissemination of new mathematical findings and fosters communication among mathematicians. As a publication, "Archiv der Mathematik" covers a wide range of mathematical topics, including but not limited to algebra, analysis, geometry, number theory, and applied mathematics.

The SI base units are the fundamental units of measurement defined by the International System of Units (SI). These units serve as the foundation from which other units of measurement are derived. There are seven SI base units, each corresponding to a specific physical quantity: 1. **Meter (m)** - the unit of length. 2. **Kilogram (kg)** - the unit of mass. 3. **Second (s)** - the unit of time.

The Day-Night Average Sound Level (Ldn or DNL) is a noise metric used primarily to assess the impact of environmental noise, particularly in urban areas and near transportation facilities like airports and highways. It is a 24-hour average sound level that accounts for both the daytime and nighttime noise levels, with a weighting factor that penalizes nighttime noise.

A noise dosimeter is a specialized device used to measure an individual's exposure to noise over a period of time. It is commonly used in occupational health and safety to ensure that workers are not exposed to harmful levels of noise, which can lead to hearing loss and other health issues. Key features of a noise dosimeter include: 1. **Personal Monitoring**: Noise dosimeters are typically worn by individuals to assess their personal noise exposure, often during a full work shift.

The Cauchy stress tensor is a fundamental concept in continuum mechanics that describes the internal state of stress at a point within a material. It provides a way to quantify how internal forces are distributed within a material due to external loads, deformations, or other influences.

The Piola-Kirchhoff stress tensors are mathematical constructs used in the field of continuum mechanics to describe the state of stress in a deformable body. They provide a way to relate the stresses in a material to its deformation, capturing both the current configuration and the reference (or undeformed) configuration of the material.

Direct insolation refers to the amount of solar radiation received on a surface from the sun, without any scattering or reflection by the atmosphere or surrounding objects. It is an important parameter in fields such as solar energy, meteorology, and climate studies, as it directly impacts the amount of energy available for solar panels and influences local temperature and weather patterns.

Mie scattering is a type of light scattering that occurs when light interacts with particles that are roughly the same size as the wavelength of the light. It is named after the German physicist Gustav Mie, who developed a mathematical solution to describe the scattering of electromagnetic waves by spherical particles. Mie scattering differs from Rayleigh scattering, which occurs with smaller particles (much smaller than the wavelength of light) and is responsible for phenomena like the blue color of the sky.

Runway Visual Range (RVR) is a measurement used in aviation that indicates the distance a pilot can see down the runway. This metric is particularly important for assessing visibility conditions, especially during takeoff and landing operations. RVR is typically measured in meters or feet and is derived from information obtained from runway lighting systems or visibility sensors. RVR readings help pilots and air traffic control determine whether conditions are suitable for landing or takeoff.

Viscosity is a measure of a fluid's resistance to flow. It quantifies how thick or sticky a liquid is and is an important property in various fields, including physics, engineering, and fluid dynamics. There are two main types of viscosity: 1. **Dynamic Viscosity (Absolute Viscosity)**: This measures the internal resistance of a fluid to gradual deformation by shear stress or tensile stress.

The unit of power is the watt (symbol: W). It is defined as one joule per second (1 W = 1 J/s). Power measures the rate at which energy is transferred or converted. In addition to watts, there are several other units of power that are commonly used: 1. **Kilowatt (kW)**: Equal to 1,000 watts (1 kW = 1,000 W).
