A moving average crossover is a popular trading strategy used in technical analysis for identifying potential buy or sell signals in financial markets. It involves two or more moving averages of an asset's price, which help to smooth out price data and identify trends. ### Key Concepts: 1. **Moving Average (MA)**: This is a calculation that takes the average price of a security over a specific number of periods.

Seasonal adjustment is a statistical technique used to remove the effects of seasonal variations in time series data. Many economic and financial indicators, such as employment rates, retail sales, and production figures, often exhibit regular patterns that recur in a predictable manner at specific times of the year, such as holidays or harvest seasons. These seasonal variations can distort the underlying trends in the data. By applying seasonal adjustment, analysts aim to produce a clearer view of the underlying trends by isolating and removing these predictable seasonal influences.

"Revisited" is a compilation album by American satirical songwriter Tom Lehrer, released in 1960. The album features a selection of Lehrer’s well-known songs, showcasing his unique blend of wit, humor, and musical talent. It includes tracks that cover various subjects, often highlighting social and political themes of the time with a humorous and satirical edge. The album has become a classic in Lehrer's discography and is representative of his style, characterized by clever lyrics and catchy melodies.

Parker Brothers is an American toy and game company established in 1883 by George S. Parker, Charles Parker, and Edward Parker. It became widely known for producing classic board games, including "Monopoly," "Clue" (known as "Cluedo" in some regions), "Risk," and "Sorry!" Over the years, Parker Brothers has contributed significantly to the gaming industry, creating games that have become beloved household staples.

As of my last knowledge update in October 2023, Tonka refers to a brand known primarily for its toys, particularly dump trucks and construction vehicles. It is not widely recognized for producing television series.

A **planar graph** is a graph that can be drawn on a plane without any edges crossing each other. In other words, it's possible to lay out the graph in such a way that no two edges intersect except at their endpoints (the vertices). Key characteristics of planar graphs include: 1. **Planar Representation**: If a graph is planar, it can be represented in two dimensions such that its edges only intersect at their vertices.

A **cycle double cover** of a graph is a particular type of subgraph that consists of a collection of cycles in which each edge of the original graph is included in exactly two of these cycles. More formally, for a given graph \( G \), a cycle double cover is a set of cycles such that every edge in \( G \) is covered exactly twice by the cycles in the set.

"Dessin d'enfant" is a French term that translates to "children's drawing." In the context of art, it often refers to the style and characteristics of drawings made by children. These drawings are typically marked by their simplicity, spontaneity, and unique perspective. They reflect a child's imagination, interpretation of the world, and emotional expression without the constraints that often accompany adult artistic conventions.

A Graph-encoded map is a representation of spatial information using graph theory concepts. In this context, a graph consists of nodes (or vertices) and edges (or connections) that connect these nodes. Graph-encoded maps are often used in various fields, such as computer science, transportation, geography, and robotics, to model and analyze complex relationships and pathways in spatial environments.

A "queue number" generally refers to a numerical value assigned to a person or item in a queue (or line), indicating their position relative to others waiting for service, access, or processing. This concept is commonly used in various settings, including: 1. **Customer Service**: In banks, restaurants, and service centers, customers receive queue numbers to organize the order in which they will be served.

A topological graph is a mathematical structure that combines concepts from topology and graph theory. In a topological graph, the vertices are points in a topological space, and the edges are curves that connect these vertices. The edges are typically drawn in such a way that they do not intersect each other except at their endpoints (which are the vertices).

A "skipping tornado" is not a widely recognized term in meteorology, but it may refer to a tornado that appears to have a non-continuous or intermittent path as it touches down and then lifts back into the cloud, only to potentially touch down again later. This phenomenon can sometimes give the visual impression of the tornado "skipping" along the ground rather than maintaining a constant, continuous path.

The Grothendieck trace theorem is a result in algebraic geometry and algebraic topology that connects the concepts of trace, a type of linear functional, with the notion of duality in the setting of coherent sheaves on a variety or topological space. While often discussed in various contexts, it is particularly notable in relation to étale cohomology and L-functions in number theory.

A **loop group** is a concept from mathematics, particularly in the fields of algebraic geometry, differential geometry, and mathematical physics. It typically refers to a specific kind of group associated with loops in a manifold, particularly in the context of Lie groups.

The Schwartz kernel theorem is a fundamental result in the theory of distributions and functional analysis, primarily dealing with the relationship between linear continuous functionals on spaces of smooth functions and distributions. In simple terms, the theorem states that any continuous linear functional on the space of compactly supported smooth functions can be represented as an integral against a distribution, which is often referred to as the "kernel" of that functional.

An essentially finite vector bundle is a specific type of vector bundle that arises in the context of algebraic geometry and differential geometry. While there isn’t a universally accepted definition across all mathematical disciplines, the term generally encapsulates the idea of a vector bundle that has a finite amount of "variation" in some sense.

Villarceau circles are a geometric concept associated with the study of toroidal shapes, specifically in relation to the geometry of a torus. These circles are defined by the intersection of a torus and a plane that cuts through it at a specific angle. When a torus is intersected by a plane not perpendicular to its central axis, the resulting intersection can yield various curves. If the angle of the plane is chosen correctly, the intersection forms a circle.

Hamilton Invaders is a term that could refer to a few different things, but it is likely associated with a local sports team or a gaming community. For instance, it may refer to the Hamilton Invaders, a junior ice hockey team based in Hamilton, Ontario, Canada. This team has historically been part of various leagues and provides opportunities for young athletes to compete at an elite level.

Lilapsophobia is the intense fear of tornadoes and hurricanes. Individuals who suffer from this phobia may experience significant anxiety or panic at the thought of such storms occurring, or even when they hear about them in the news. Like other specific phobias, lilapsophobia can lead to avoidance behaviors, affecting a person's daily life, especially in areas prone to severe weather.

Tornadogenesis refers to the process by which a tornado forms. It typically occurs within severe thunderstorms, specifically supercell thunderstorms, which have a well-defined rotating updraft called a mesocyclone. The process involves several meteorological factors, including: 1. **Wind Shear**: The variation in wind speed and direction with height creates a horizontal spinning effect.
