Safety glass
Safety glass is a type of glass that is designed to minimize the risk of injury when broken. It is made to be more resistant to breaking and to shatter into small, less harmful pieces rather than sharp shards that can cause serious injury. There are several types of safety glass, each with specific applications and manufacturing processes, including: 1. **Tempered Glass**: Also known as toughened glass, it is produced by heating glass to high temperatures and then rapidly cooling it.
Sliding glass door
A sliding glass door is a type of door that consists of one or more panels of glass that slide horizontally along a track to open and close. These doors are commonly used in residential and commercial settings as an entrance to patios, decks, backyards, balconies, or even as room dividers. **Key features of sliding glass doors include:** 1.
Smart glass
Smart glass, also known as switchable glass or electrochromic glass, refers to a type of glass that can change its properties in response to an external stimulus, such as an electrical current, heat, or light. This technology is often used to modify light transmission, privacy, and temperature control in architectural applications. There are various types of smart glass, each operating on different principles: 1. **Electrochromic Glass**: This type changes color or opacity when a small voltage is applied.
Solarized architectural glass
Solarized architectural glass refers to a type of glass used in building design and construction that incorporates solar control features, typically to manage heat gain and glare from sunlight. This glass is often treated or coated with special materials to enhance its performance in terms of energy efficiency and comfort within indoor environments. Key features of Solarized architectural glass include: 1. **Solar Control:** It minimizes the amount of solar radiation that enters a building, helping to maintain a comfortable indoor temperature and reducing reliance on air conditioning.
Defense Advanced GPS Receiver
The Defense Advanced GPS Receiver (DAGR) is a highly specialized Global Positioning System (GPS) receiver developed for military applications. It is designed to provide accurate and reliable positioning, navigation, and timing information, which is critical for a variety of defense operations. Here are some key features and characteristics of the DAGR: 1. **Robust Design**: The DAGR is built to withstand harsh environmental conditions typically encountered in military operations, including extreme temperatures, vibration, and moisture.
Differential GPS
Differential GPS (DGPS) is an enhancement to the Global Positioning System (GPS) that provides improved location accuracy by correcting the signals received from GPS satellites. While standard GPS can provide accuracy within about 10 to 20 meters under ideal conditions, DGPS can improve that accuracy to within 1 to 3 meters. ### How DGPS Works: 1. **Reference Stations**: DGPS relies on a network of fixed ground-based reference stations that know their exact position.
The United States Congressional Joint Committee on Atomic Energy was a legislative body established in 1946 to oversee atomic energy matters in the United States. Its primary purpose was to address issues related to the development, regulation, and control of atomic energy, especially in the context of national security, military applications, and civilian uses of nuclear technology. The committee played a significant role in shaping U.S. nuclear policy during the early years of the Cold War.
Dead reckoning
Dead reckoning is a navigation method used to determine one's current position based on a previously determined position, taking into account speed, direction, and time traveled. This technique is often utilized in aviation, marine navigation, and land navigation when GPS or other advanced navigational systems are not available.
Local purchasing
Local purchasing refers to the practice of buying goods and services from vendors, suppliers, or producers within a specific geographic area. This approach prioritizes the acquisition of products and services that come from nearby sources, thereby supporting local economies. Key aspects of local purchasing include: 1. **Economic Support**: By purchasing from local businesses, consumers help stimulate the local economy, which can lead to job creation and community development.
Locata Corporation
Locata Corporation is a company that specializes in the development and provision of advanced positioning technologies. Founded in the 1990s, Locata focuses on solutions that offer precise location tracking and navigation, particularly in environments where traditional Global Navigation Satellite Systems (GNSS), like GPS, may not be effective due to obstructions or interference, such as indoor spaces or urban canyons. The company's technology includes the use of ground-based transmission systems that can provide highly accurate positioning services.
Glass beaches
Glass beaches are coastal areas where the shore is covered with smooth, colorful pieces of glass instead of sand, pebbles, or shells. This unique phenomenon occurs when discarded glass objects, often from bottles or other containers, are broken down by the action of the waves and weather over time. The process polishes the glass, turning sharp edges into smooth, rounded pieces, which can vary in color depending on the original glass materials.
Glass dyes
Glass dyes, also known as glass stains or glass coloring agents, are substances specifically designed for coloring glass. These dyes can be used in various glassworking techniques, including glassblowing, glass fusing, and glass painting. The primary purpose of glass dyes is to change the color of glass either during the manufacturing process or as a finishing touch. Typically, glass dyes are made from metallic oxides or other colorant materials that are capable of withstanding high temperatures involved in glass crafting.
Glass engineering and science
Glass engineering and science involves the study and application of the properties, production, and use of glass materials. This interdisciplinary field encompasses various aspects including chemistry, physics, and materials science, and can be divided into a few key areas: 1. **Materials Science**: Understanding the composition, structure, and properties of glass and the effects of different materials on its behavior. This includes studying different types of glass, such as silica glass, borosilicate glass, and specialty glasses used for specific applications.
Glass in nature
In nature, "glass" typically refers to a naturally occurring form of silica (SiO2) that has a glassy or amorphous structure. The most common examples include: 1. **Obsidian**: This volcanic glass is formed from rapidly cooled lava. It is typically dark, often black, and has a smooth, shiny surface. Its structure is amorphous, lacking a regular crystalline arrangement.
Glass stubs
"Glass stubs" can refer to several contexts depending on the field in which it is used. Here are a few possibilities: 1. **Laboratory Equipment**: In a laboratory setting, glass stubs may refer to small glass structures used for mounting samples for microscopic examination. These stubs are typically coated with a conductive material for electron microscopy.
History of glass
The history of glass dates back thousands of years and reflects the evolution of technology, art, and culture across various civilizations. Here’s an overview of its development through time: ### Ancient Beginnings (Circa 3500 BCE) - **Mesopotamia and Egypt:** The earliest known glass artifacts date back to around 3500 BCE in Mesopotamia and Egypt. These early forms were primarily used for making small beads and ornamental objects rather than for containers or windows.
