The term "Santa Claus machine" typically refers to a theoretical concept in computer science and cryptography involving a specific kind of payment mechanism or a method of verifying cryptographic tasks, particularly in the context of fair exchange protocols. The idea is often related to ensuring that a participant can receive some value (like a digital asset or information) without needing to trust the other party completely, similar to how children trust Santa Claus to deliver gifts.

A list of artillery by country typically includes the various types of artillery systems that are used or have been developed by different nations. This can encompass several categories, such as field artillery, howitzers, self-propelled guns, mortars, and coastal artillery, among others. Below is a general overview of notable artillery systems by country, although it is not exhaustive. ### United States - **M777 Howitzer**: A lightweight towed 155 mm artillery piece.

The Nottingham Asphalt Tester (NAT) is a specialized laboratory device used to evaluate the mechanical properties of asphalt mixtures, particularly focusing on their performance under a variety of conditions. It plays a critical role in assessing the durability and structural integrity of asphalt pavements. ### Key Features and Functions: 1. **Testing Mechanism**: The NAT typically uses a series of loading cycles to simulate the stresses that asphalt pavements encounter in real-world conditions.

The perifocal coordinate system is a framework used in orbital mechanics to describe the position and velocity of an object in orbit around a central body, such as a planet or star. In this system, the coordinates are defined relative to the orbital parameters of the body in question. Here's how the perifocal coordinate system is structured: 1. **Perifocal Plane**: The plane in which the orbit lies is called the perifocal plane.

A Hohmann transfer orbit is an elliptical orbit used to transfer a spacecraft between two circular orbits of different altitudes around a celestial body, typically a planet. This maneuver is named after the German engineer Walter Hohmann, who described it in 1925.

The mass ratio is a comparison of the mass of one substance to the mass of another substance. It is often expressed as a fraction or a ratio and is used in various fields such as chemistry, physics, and engineering to understand the relationship between different materials or components in a system.

Fakhr al-Din al-Akhlati (also known as Fakhr al-Din al-Akhlaqi or al-Akhawati) was a prominent Persian poet and philosopher from the 12th century.
