Annick Horiuchi is a prominent figure known for her contributions to various fields, particularly in international relations and economics. She may also be involved in academia or research, focusing on issues such as global governance or economic development. However, for the most precise and updated information about her work and impact, it would be best to consult recent publications or official profiles.
Paul Tannery (1848-1904) was a notable French philologist and historian of science, particularly known for his work in the history of mathematics and astronomy. He is perhaps best recognized for his studies on the contributions of ancient civilizations to these fields, especially focusing on the mathematics of the Greeks and the astronomical practices of the Babylonians. In addition to his scholarly research, Tannery was involved in education and was a member of several academic societies.
Raphaël Granier de Cassagnac is a French journalist and writer, known for his work as an editorial writer and for his contributions to various media outlets. He has been involved in debates on topics such as contemporary political issues, cultural commentary, and social phenomena in France. His perspectives often reflect a blend of journalism and personal commentary, engaging with current events and the socio-political landscape.
A ridge function is a specific type of function that can be expressed as a composition of a function of a single variable and a linear combination of its inputs.
Direct Fusion Drive (DFD) is a proposed propulsion technology primarily for space travel that combines nuclear fusion with electric propulsion. Developed by the Focused Energy group at the University of Buffalo and other institutions, the DFD aims to utilize nuclear fusion reactions to provide thrust for spacecraft. Here are some key features of Direct Fusion Drive: 1. **Nuclear Fusion**: DFD utilizes fusion reactions, specifically those occurring between deuterium and helium-3 isotopes.
The Brazilian Mathematical Society (Sociedade Brasileira de Matemática, or SBM) is a professional organization dedicated to the promotion and development of mathematics in Brazil. Founded in 1969, its main objectives include: 1. **Promoting Mathematical Research and Education**: SBM fosters research in various fields of mathematics and aims to improve the quality of mathematics education at all levels in Brazil.
Coastal upwelling in the South Eastern Arabian Sea is a phenomenon characterized by the rising of deeper, colder, and nutrient-rich water to the surface along the coast. This process is driven primarily by wind patterns and ocean currents. Here's a more detailed explanation of the dynamics and significance of this phenomenon: ### Mechanism of Upwelling 1. **Wind Patterns**: The South Eastern Arabian Sea is affected by the monsoon winds, particularly during the southwest monsoon season (June to September).
Sammon mapping is a technique used in the field of multidimensional scaling and dimensionality reduction. It is particularly useful for visualizing high-dimensional data in lower-dimensional spaces, typically two or three dimensions. The method aims to preserve the pairwise distances between data points as well as possible when projecting them into a lower-dimensional space.
The Splitting Lemma is a concept often discussed in the context of functional analysis, particularly in the study of normed spaces and topological vector spaces. Though it is not universally defined across all mathematical disciplines, the most common interpretations and applications of the Splitting Lemma relate to properties of continuous linear maps and the behavior of certain types of vector spaces.
Unimodality is a property of a function or a dataset that describes its tendency to have a single "peak" or mode. In mathematical terms, a function is unimodal if it has only one local maximum (peak) and one local minimum (trough), such that the function increases to that maximum and then decreases thereafter, or vice versa.
A fusion rocket is a type of propulsion system that utilizes nuclear fusion reactions to generate thrust. In theory, it harnesses the energy released when light atomic nuclei, such as isotopes of hydrogen (like deuterium and tritium), combine to form heavier nuclei. This process releases a substantial amount of energy, which could be used to propel a spacecraft.
Howard Raiffa (1924-2016) was a prominent American mathematician and a key figure in the fields of decision science, operations research, and game theory. He made significant contributions to the understanding of decision-making under uncertainty and the processes involved in negotiation and conflict resolution. Raiffa is well-known for his work on the development of analytical frameworks for making decisions, including the concept of multi-criteria decision analysis.
Jean Tirole is a prominent French economist known for his work in the fields of industrial organization, game theory, and regulation. He was awarded the Nobel Prize in Economic Sciences in 2014 for his analysis of market power and regulation, particularly in relation to monopolies and oligopolies. Tirole's research has significantly influenced the understanding of how firms interact in markets and how regulators can design policies to promote competitive behavior and improve market outcomes.
A **sequential game** is a type of game in game theory where players make decisions one after another, rather than simultaneously. This structure allows players to observe previous actions before making their own decisions, which can influence their strategies and outcomes. ### Key Characteristics of Sequential Games: 1. **Order of Moves**: Players take turns making decisions. The order in which players move can affect the strategies they choose.
In mathematics, "closeness" often refers to a concept related to the distance between points, objects, or values in a particular space. It can be defined in various contexts, such as in metric spaces, topology, and real analysis.
Two-sided matching is a concept from economics and game theory that refers to the process of pairing individuals or entities from two different groups based on their preferences and characteristics. The most well-known application of two-sided matching is in labor markets, where employers and job seekers need to find suitable matches based on preferences (e.g., a job candidate's skills and an employer's job requirements).
Fusion power technologies encompass a variety of methods and concepts aimed at harnessing nuclear fusion—the process that powers the sun and other stars—for practical energy production. Here’s a list of some key fusion power technologies and concepts: ### 1. **Magnetic Confinement Fusion (MCF)** - **Tokamak**: A doughnut-shaped device using magnetic fields to confine hot plasma. ITER (International Thermonuclear Experimental Reactor) is a prominent example.
