Oliver Lodge can refer to two distinct subjects: 1. **Oliver Lodge (physicist)**: Sir Oliver Lodge (1851–1940) was a British physicist and writer, known for his work in the fields of electromagnetism and radio waves. He was one of the pioneers of wireless communication and is credited with important contributions to the development of the spark-gap transmitter. Lodge was also involved in early experiments with radio and made notable contributions to the understanding of electromagnetic radiation.

The Ultra-short Baseline (USBL) acoustic positioning system is a technology used for determining the position of underwater objects, such as submersibles, remotely operated vehicles (ROVs), and other underwater installations. USBL systems rely on the propagation of acoustic signals in water to calculate positions based on the time it takes for sound waves to travel between a surface vessel and underwater targets.

Richard Glazebrook is not widely known as a public figure or a prominent individual in historical or contemporary contexts up until my last update in October 2023. It's possible that he could refer to a person not extensively covered in mainstream media, or he might be a fictional character or a private individual.

Ted Bastin could refer to a person or a specific topic, but without additional context, it's challenging to provide a precise answer. If you are referring to a notable individual, there may not be widely-known information available, as my training data includes public figures, but not every individual.

Roger Elliott is a physicist known for his contributions to the field of condensed matter physics, particularly in the areas of superconductivity and magnetism.

Stephen Butterworth is a name that could refer to several individuals across different fields. For example, he could be a scholar, a professional in a specific industry, or even a character in literature or media. Without more context, it’s difficult to provide a precise answer.

William Duddell (1872–1917) was an English electrical engineer and inventor known primarily for his work on the musicality of oscillators and for developing the Duddell oscillator. This device was an early form of an electronic oscillator, which used a mechanical resonator, and was significant in the advancement of electronic sound generation. It contributed to the development of early electronic music instruments and sound synthesis.

Thomas Guidott was a notable figure in the 17th century, recognized primarily as a physician, writer, and advocate for the practice of medicine. He is particularly known for his work related to the medicinal properties of minerals and waters, and he made contributions to the understanding of mineralogy. He is often associated with the study of natural history and was involved in the development of early scientific thought in England.

Kullback-Leibler divergence, often abbreviated as KL divergence, is a measure from information theory that quantifies how one probability distribution diverges from a second, expected probability distribution. It is particularly useful in various fields such as statistics, machine learning, and information theory.

The Akaike Information Criterion (AIC) is a statistical measure used for model selection among a set of models. It is particularly useful when comparing different statistical models fitted to the same dataset. The AIC provides a means to evaluate how well a model explains the data, while also accounting for the complexity of the model to prevent overfitting.

Line-intercept sampling is a method used in ecological studies to assess the abundance and distribution of organisms, particularly in vegetation or species within a defined area. This technique involves laying out a predetermined line (or transect) across a specific habitat and then recording the organisms that intersect with the line. ### How it Works: 1. **Transect Line Establishment**: A straight line (transect) is established across the study area.

The Maximum Entropy (MaxEnt) probability distribution is a principle used in statistics and information theory to derive the probability distribution that best represents a set of known constraints while making the least additional assumptions. The fundamental idea is to maximize the Shannon entropy subject to certain constraints, typically represented by expected values of some functions.

**Plot sampling** is a technique commonly used in ecology, forestry, and environmental science to collect data about vegetation or wildlife within specific areas, known as plots. This method allows researchers to gather quantitative data about the characteristics of ecosystems or populations, helping them to assess biodiversity, species abundance, biomass, and other ecological parameters. ### Key Aspects of Plot Sampling: 1. **Fixed vs.

In mathematics, a partition function is a function that counts the number of ways a given positive integer can be expressed as a sum of positive integers, disregarding the order of the addends. Formally, the partition function \( p(n) \) is defined as the number of partitions of the integer \( n \).

Environmental radioactivity refers to the presence and concentration of radioactive materials in the environment, including air, water, soil, and living organisms. This radioactivity is a natural phenomenon resulting from the decay of radioactive isotopes that are found in the earth's crust, cosmic radiation from outer space, and human-made sources. **Sources of Environmental Radioactivity:** 1. **Natural Sources:** - **Cosmic Rays:** High-energy particles from outer space that contribute to background radiation.

Tritium is a radioactive isotope of hydrogen, denoted as \( ^3H \) or T. It contains one proton and two neutrons in its nucleus, making it heavier than the most common hydrogen isotope, protium (\( ^1H \)), which has only one proton and no neutrons. Tritium is produced naturally in the atmosphere through interactions between cosmic rays and nitrogen.
