In electrical engineering, particularly in the context of transmission lines and microwave engineering, "stubs" refer to short sections of transmission lines that are used to manipulate electrical signals, impedance, or perform tuning. Here's a general overview of what stubs are and their applications: ### Types of Stubs 1. **Open-circuit Stub**: A transmission line segment that is terminated at one end by an open circuit. It can be used to add inductive reactance.
Randomized algorithms in the context of zero-sum games involve strategies where players use randomness in their decision-making process to optimize their expected outcomes against their opponents. A zero-sum game is a situation in game theory where one player's gain is exactly balanced by the losses of another player. In simpler terms, the total utility or payoff available to all players is constant; one player's profit comes at the expense of another's loss.
Several computer companies were disestablished in 1994. Some notable examples include: 1. **Commodore International** - Once one of the major players in the home computer market, Commodore filed for bankruptcy and ceased operations in 1994. The company is well-known for its Commodore 64 and Amiga computers.
"Figurines" can refer to small statues or models that represent a specific figure, character, or object, often used for decoration, collection, or as toys. These figurines can be made from various materials, including plastic, ceramic, metal, or wood, and they can depict anything from animals to human figures to fictional characters from movies and games.
A ball-jointed doll (BJD) is a type of articulated doll that is made from materials such as resin or plastic, featuring joints that allow for a wide range of poses and movements. These dolls typically have spherical joints, giving them greater flexibility and the ability to be customized and posed in various ways. BJDs originated in Asia, particularly in countries like Japan and South Korea, where they have become popular among collectors, artists, and hobbyists.
"Black doll" can refer to a few different concepts depending on the context: 1. **Cultural Symbol**: The term can refer to dolls made to represent Black children, often used to promote diverse representation and inclusiveness in toys. These dolls aim to reflect the beauty and diversity of Black culture and provide children with relatable figures.
The term "China doll" can refer to a couple of different things, depending on the context: 1. **Porcelain Doll**: A "China doll" is often a type of doll made from porcelain or china, characterized by its delicate features, painted facial expressions, and sometimes intricate clothing. These dolls have been popular collectibles, especially in the 19th and early 20th centuries. They are known for their fragile nature and often depict various historical or cultural themes.
Katashiro refers to a traditional practice in Japan where a straw figure or doll is made and used in Shinto rituals. The creation of these figures is often associated with the belief that they can absorb bad fortune or illness, acting as a surrogate for a person during ceremonies. Typically, katashiro are created at certain festivals or during specific times of the year, such as New Year's or during harvest festivals.
A voodoo doll is a pop culture representation often associated with the religious practice of Voodoo, which originates from West African spiritual traditions and is particularly associated with Haiti and Louisiana. In popular belief, a voodoo doll is a figure that represents a person, and practitioners use it to influence or affect that person in some way—typically to cause harm, though it can also be used for healing or protection.
Christian Doppler was an Austrian physicist and mathematician best known for his work in the field of wave theory, particularly for formulating the Doppler effect. Born on November 29, 1803, and passing away on March 17, 1853, he made significant contributions to the understanding of sound and light waves.
Silverman's game is a mathematical game that serves as an example in game theory. It involves two players who take turns choosing numbers from a set of positive integers, with the goal of achieving a certain outcome or condition based on the numbers chosen. The rules of the game can vary, but generally, the game illustrates strategic decision-making, optimal play, and can showcase concepts such as Nash equilibria or minimax strategies.
Control of chaos refers to techniques and strategies used to manage and influence chaotic systems in a way that allows for predictable behavior or desired outcomes. Chaos theory studies complex systems that are highly sensitive to initial conditions, meaning that small changes can lead to vastly different results. Such systems are often described by nonlinear dynamics and can be found in various fields, including physics, biology, economics, and engineering.
Hans Breuer is a physicist known for his contributions to the fields of experimental and theoretical physics. While specific details about his work and accomplishments might not be widely publicized, he is recognized within certain academic circles.
Hans Hellmann is not a widely recognized public figure, but the name could refer to various individuals or contexts depending on the specific area of interest, such as academia, literature, or other fields.
Kant's antinomies are a series of contradictions that arise from the application of pure reason to metaphysical concepts, particularly in his work "Critique of Pure Reason." In this context, an antinomy refers to a situation where two compelling, yet mutually contradictory, arguments can be made regarding the same issue.
Several computer companies were disestablished in 1995. Some notable ones include: 1. **Apollo Computer** - A company known for its workstations and networking products, which was acquired by Hewlett-Packard in 1989 but continued some operations until officially being absorbed around 1995. 2. **DEC (Digital Equipment Corporation)** - Although DEC was acquired by Compaq in 1998, certain parts of DEC's operations and branding were phased out around 1995.
In photography, the "golden hour" refers to the period of time shortly after sunrise and before sunset when the natural light is particularly soft, warm, and golden in color. This specific lighting condition is highly sought after by photographers because it creates flattering and visually appealing images, with enhanced depth and texture. During the golden hour, the sun is low in the sky, which results in longer shadows and a more diffused light, reducing harsh contrasts.
