Topics might include numerical analysis, optimization, mathematical modeling, and computational mathematics, among others. The journal is typically peer-reviewed, which means that submitted articles undergo evaluation by experts in the field before being accepted for publication.

Astérisque can refer to different things depending on the context. Here are a few possible interpretations: 1. **Asterisk Symbol**: In typography, an asterisk (*) is a typographical symbol used for various purposes, such as indicating footnotes or marking important information. 2. **Astérisque (Journal)**: It is the title of a mathematical research journal published by the Société Mathématique de France. The journal publishes articles on various areas of mathematics.

AlterGeo was a location-based advertising and analytics platform that provided services primarily for businesses looking to engage customers through location tracking and targeted advertising. The platform utilized geolocation data to help companies create customized marketing campaigns that reached users based on their physical location, thereby increasing the relevance and effectiveness of those campaigns. In addition to its advertising services, AlterGeo also offered analytics tools that allowed businesses to measure the effectiveness of their location-based marketing strategies, track customer interactions, and analyze foot traffic patterns.

"Analysis and Applications" can refer to a range of concepts depending on the context. Here are a few interpretations across different fields: 1. **Mathematics (Real/Complex Analysis)**: In mathematics, analysis typically deals with the study of limits, continuity, differentiation, integration, and sequences. Applications can involve using these concepts in various fields such as physics, engineering, economics, and statistics.

"Annales de l'Institut Fourier" is a scientific journal that publishes research articles in the fields of mathematics, particularly in analysis, geometry, and related areas. Established in 1950, the journal is named after Joseph Fourier, a prominent mathematician known for his work in mathematical analysis and its applications. It is associated with the Institut Fourier, which is a research institute in Grenoble, France. The journal is known for its rigorous peer-review process and its focus on high-quality original research.

Frequency, in a general sense, refers to the number of occurrences of a repeating event per unit of time. It is commonly used in various fields, including physics, music, and electronics. Here are a few specific contexts where the term "frequency" is relevant: 1. **Physics**: In wave mechanics, frequency is the number of cycles of a wave that pass a given point in one second.

NOC, which stands for "Norwegian orca," is a term associated with a specific case of an orca (also known as a killer whale) that gained attention due to its unusual vocalizations. In 1984, a captive orca named NOC at the National Marine Aquarium in San Diego was observed to have mimicked human speech patterns. Researchers recorded sounds that resembled human voices, leading to discussions about the cognitive capabilities of marine mammals, particularly orcas.

A noise map is a graphical representation that illustrates the distribution and level of noise in a particular area. It is used to analyze and assess noise pollution, providing important information for urban planning, environmental management, and public health. Noise maps typically indicate areas with different noise levels, often using color codes or shading to represent varying decibel levels. Noise maps can be created using various methods, including: 1. **Field Measurements**: Directly measuring noise levels at different locations and times.

The electromagnetic tensor, also known as the Faraday tensor, is a mathematical object in the field of electromagnetism that encapsulates the electric and magnetic fields into a single antisymmetric rank-2 tensor. It is an essential component of the framework of relativistic electrodynamics and is fundamental in the context of both special and general relativity.

Fog is a type of weather phenomenon characterized by low-lying clouds that reduce visibility near the Earth's surface. It forms when moisture in the air condenses into tiny water droplets, often resulting in a thick, cloud-like layer that obscures vision. Fog can occur in various forms, including: 1. **Radiation Fog**: Forms overnight when the ground cools rapidly, leading to condensation of moisture near the surface.

The Angstrom exponent, often denoted as α (alpha), is a dimensionless quantity used in atmospheric science to describe the wavelength dependence of aerosol optical depth (AOD) or aerosol extinction. It is particularly important in characterizing how aerosol particles scatter and absorb solar radiation, which can have implications for climate and weather.

The "blue hour" refers to the period of twilight after sunset or before sunrise when the sky takes on a deep blue hue. This phenomenon occurs when the sun is below the horizon but still illuminates the atmosphere, scattering the shorter wavelengths of light. The blue hour is particularly favored by photographers and artists because of the soft, diffused light it creates, which can enhance the mood and color of the landscape.
