Active updating can refer to a variety of contexts depending on the field in which it is used. Here are a few interpretations: 1. **Software and Data Management**: In the context of software applications or databases, active updating may refer to the continuous or frequent updating of data or software features to reflect real-time information or user interactions. For example, applications that provide live updates on news, stock prices, or social media feeds are engaged in active updating.

The activity coefficient is a factor used in thermodynamics and physical chemistry to quantify the deviation of a solution's behavior from that of an ideal solution. It is defined as the ratio of the activity of a species to its concentration (or mole fraction in the case of ideal solutions).

In Unified Modeling Language (UML), an **Actor** represents a role that a user or any other system plays when interacting with the system being modeled. Actors are typically used in use case diagrams to illustrate the interactions between the system and the external entities that influence its behavior. ### Key Characteristics of Actors in UML: 1. **External Role**: An actor is not part of the system itself; instead, it exists outside the system and interacts with it.

A tape measure, also known as a measuring tape, is a flexible tool used to measure distance or length. It typically consists of a long, thin strip of cloth, plastic, or metal marked with measurement units (usually in inches and centimeters). Tape measures are commonly used in construction, carpentry, sewing, and various fields that require precision in measuring lengths and dimensions.

The Adamic–Adar index is a measure used in network theory and social network analysis to quantify the similarity between two nodes based on their shared connections. Specifically, it evaluates the likelihood that two nodes will connect in the future, based on their common neighbors in a graph.

Adam Morton is a philosopher known for his work in areas such as epistemology, ethics, and the philosophy of action. He has contributed to discussions on topics like the nature of belief, the role of emotions in moral reasoning, and the complexities of human motivation. Morton has also written on the implications of philosophy for real-world issues, exploring how theoretical concepts can interface with practical concerns.

Adam Wierman is a professor in the Department of Computing and Mathematical Sciences at the California Institute of Technology (Caltech). His research interests primarily include areas such as queuing theory, machine learning, and algorithms, often with applications in networking, data analysis, and other fields. He has contributed to various topics in operations research and has published numerous papers in academic journals.

Additive smoothing, also known as Laplace smoothing, is a technique used in probability estimates, particularly in natural language processing and statistical modeling, to handle the problem of zero probabilities in categorical data. When estimating probabilities from observed data, especially with limited samples, certain events may not occur at all in the sample, leading to a probability of zero for those events. This can be problematic in applications like language modeling, where a lack of observed data can lead to misleading conclusions or unanticipated behavior.

**Addyston Pipe & Steel Co. v. United States** is a significant U.S. Supreme Court case from 1899 that dealt with issues of antitrust law and the legality of business practices that could be deemed anti-competitive. The case arose when Addyston Pipe and Steel Company, along with other companies, was accused of engaging in a conspiracy to fix prices and allocate markets for the manufacture and sale of cast iron pipe. The U.S.

Futaba Corporation is a Japanese company known primarily for its production of various electronic components and devices. Established in 1948, Futaba has specialized in manufacturing items such as display devices, including liquid crystal displays (LCDs) and vacuum fluorescent displays (VFDs), as well as other electronic components like connectors and control units. The company's products are commonly used in various industries, including automotive, consumer electronics, industrial equipment, and telecommunications.

In set theory, particularly in the context of descriptive set theory, the concept of "adequate pointclasses" arises in the study of definable sets of real numbers and more general topological spaces. A pointclass is a collection of subsets of a space (like the real numbers or other Polish spaces) that can be defined using certain logical formulas or conditions, typically involving quantifiers.

The number 971 is a natural number that comes after 970 and before 972. In terms of its properties: - **Prime Number**: 971 is a prime number, meaning it has no positive divisors other than 1 and itself. - **Mathematical Characteristics**: It is odd and can be expressed in various forms, such as its binary representation (1111001101) or in hexadecimal (3CF).

Adiabatic conductivity generally refers to the thermal conductivity of a material under adiabatic conditions, which means that no heat is exchanged with the surroundings. In thermodynamics, an adiabatic process is one in which a system does not gain or lose heat to its surroundings. In the context of materials science and thermal engineering, adiabatic conductivity can be important for understanding how heat is conducted through a material when heat exchange is negligible.

"A Dialogue Concerning Oratorical Partitions" is a work by the Renaissance humanist and scholar, Erasmus of Rotterdam, published in 1532. The text is structured as a dialogue and engages in discussions about rhetoric, specifically the organization and structuring of speech, known as "partitions." In this dialogue, Erasmus examines the classical methods of oratory and rhetoric, influenced by ancient texts, particularly those of Cicero.

Adina L. Roskies is a prominent philosopher known for her work in the philosophy of mind, neuroscience, and ethics. Her research often explores themes such as free will, the nature of consciousness, and the implications of neuroscientific findings for our understanding of human agency and moral responsibility.

Westerhout 43 is a notable star-forming region located in the constellation of Sagittarius. It is recognized as a prominent prototype of H II regions, which are large clouds of gas and dust in space where new stars are born. The region is specifically part of a giant molecular cloud, and its designation reflects the work of astronomers who cataloged various stellar and nebulae objects.

Westerhout 5 (W 5) is a notable astronomical object, specifically a star-forming region, located in the constellation of Cassiopeia. It is part of a larger molecular cloud complex and is known for containing a cluster of young, massive stars. The region is of interest to astronomers because it offers insights into stellar formation processes and the dynamics of star clusters.

Greece is divided into several administrative regions, known as "peripheries" (singular: "periphery"). As of the latest administrative division, Greece is organized into 13 regions, each with its own local government. These administrative regions are further subdivided into regional units, which are similar to counties. Here are the 13 regions of Greece: 1. **Attica (Αττική)** - Surrounds the capital, Athens.
