In the 1990s, DeLorme expanded into the digital mapping and GPS space, creating software products like Topo USA, which provides users with detailed topographic maps and navigation capabilities.

Delta waves are a type of brainwave that are characterized by their low frequency (typically 0.5 to 4 Hz) and high amplitude. They are one of the five main types of brainwaves, the others being alpha, beta, gamma, and theta waves. Delta waves are predominantly present during deep sleep stages, particularly during non-REM (rapid eye movement) sleep. Key characteristics of delta waves include: 1. **Frequency**: Delta waves range from 0.

"Glass makers" refers to individuals or companies that specialize in the production of glass products. This encompasses a wide range of activities, including the crafting of glassware, containers, windows, art pieces, and industrial glass products. The process of glassmaking is complex and involves several steps, such as melting raw materials (like silica sand, soda ash, and limestone), forming the glass into the desired shape, and then cooling it to create a solid product.

Deoxycytidine triphosphate (dCTP) is one of the four nucleoside triphosphates that are used as building blocks for DNA synthesis. It is composed of three main components: 1. **Deoxyribose**: A five-carbon sugar that forms the backbone of DNA but lacks an oxygen atom at the 2' position compared to ribose, which is found in RNA.

The Department of Atomic Energy (DAE) is a department of the Government of India responsible for the country's nuclear energy program. Established in 1954, the DAE is tasked with developing nuclear technology and its applications for energy production, medical purposes, industrial applications, and research.

Optimal decisions refer to choices that yield the best possible outcome or result under a given set of constraints and criteria. These decisions are often made in the context of decision theory, economics, management, and various fields where analysis of alternatives is necessary. The concept is grounded in the idea of maximizing utility, profit, or satisfaction while minimizing costs, risks, or negative outcomes.

The Department of Mathematics at the University of Manchester is a part of the Faculty of Science and Engineering and is known for its strong emphasis on research and teaching in various areas of mathematics. The department offers undergraduate and postgraduate programs in mathematics and related fields, providing students with a solid foundation in mathematical theory as well as practical applications. The department is involved in a wide range of research areas, including pure mathematics, applied mathematics, statistics, and mathematical physics.

In the context of ring theory, "depth" is a concept that arises in commutative algebra, particularly in the study of modules over rings. Depth provides a measure of the "complexity" of the structure of a module, as well as information about the relationship between the module and its associated ring. More formally, the depth of a module \( M \) over a ring \( R \) can be defined in terms of the associated prime ideals.

The Deputy Chief of Staff for Operations, Plans, and Training (G3/5/7) is a senior staff position within the military, often found in the organizational structure of the U.S. Army or other branches of the armed forces. This role is responsible for overseeing and coordinating the strategic planning and execution of military operations, conducting training programs, and ensuring that units are prepared for various missions.

Dereverberation is the process of removing or reducing the effects of reverberation from an audio signal. Reverberation is the persistence of sound in a particular space after the original sound source has stopped, caused by reflections off surfaces like walls, floors, and ceilings. While some level of reverberation can contribute to a sound's richness, excessive reverberation can muddy audio clarity and make it difficult to understand speech or appreciate music.

Dershowitz–Manna ordering is a concept from the field of computer science, particularly in the area of term rewriting systems and automated theorem proving. It is a specific way of defining a lexicographic ordering on terms that can be used to analyze and compare the complexity of problems in rewriting systems. In more detail, Dershowitz–Manna ordering is an extension of the standard lexicographic ordering to a setting where terms may consist of variables and function symbols.

Desargues's theorem is a fundamental result in projective geometry that describes a relationship between two triangles. It states that if two triangles are in perspective from a point, then they are in perspective from a line.

Design-based learning (DBL) is an educational approach that emphasizes the processes of design as a means to engage students in active learning. It integrates principles from design thinking and focuses on problem-solving through creative methods. In DBL, students typically work on projects that require them to define a problem, ideate potential solutions, create prototypes, and iterate based on feedback.

Designing economic mechanisms refers to the process of creating rules and structures that govern how economic interactions and transactions occur within a particular system. This field is an intersection of economics, game theory, and institutional design, focusing on how to align individual incentives with desired collective outcomes. Key aspects of designing economic mechanisms include: 1. **Incentive Structures**: Creating incentives that motivate individuals and organizations to act in ways that lead to beneficial outcomes for the collective, such as efficiency, fairness, or sustainability.

Despina is one of Neptune's moons, discovered in 1989 by the Voyager 2 spacecraft. It is named after a character from Greek mythology, specifically a daughter of Poseidon. Despina is an irregularly shaped moon and is relatively small, with a diameter of about 150 kilometers (93 miles). The moon orbits Neptune at a distance of approximately 20,000 kilometers (about 12,400 miles) and completes an orbit around the planet in about 0.

Desuspension is not a widely recognized term in academic or technical literature, and its meaning can depend on the context in which it is used. However, in a general sense, "desuspension" can refer to the process of removing particles or substances that are suspended in a liquid or gas phase.

NASBA stands for Nucleic Acid Sequence-Based Amplification, which is a technique used in molecular biology for amplifying RNA targets. It is similar to the more widely known polymerase chain reaction (PCR) but is specifically designed for RNA rather than DNA. The NASBA method utilizes a combination of reverse transcription and amplification steps that occur at a constant temperature, which makes it particularly suitable for detecting RNA viruses and for applications where isothermal conditions are preferred.

The Spartan Packet Radio Experiment, often referred to as Spartan or SPARTAN, was a project developed to demonstrate the feasibility of using packet radio technology for communication and data transfer in a space environment. Specifically, it was linked to various educational and outreach initiatives, enabling students and amateur radio operators to engage in hands-on learning and experimentation with radio communications.
