Sohae has been used for various rocket launches, including satellite deployments and tests of North Korean ballistic missile technology.
Tonghae Satellite Launching Ground, also known as the Tonghae Satellite Launching Station, is a space launch facility located in North Korea near the city of Tonghae. It was established in the early 1990s and is primarily used for launching satellites into orbit. The facility has been developed to support North Korea's efforts to advance its space program and missile technology.
United Nations Security Council Resolution 1695 was adopted on July 15, 2006. The resolution was primarily aimed at responding to North Korea's missile tests conducted earlier that month. The Security Council condemned North Korea's actions, expressing concern over the threat these missile launches posed to regional and international security. The resolution called upon North Korea to cease all missile testing and to return to negotiations aimed at denuclearization of the Korean Peninsula.
The IBM 702 was one of IBM's early electronic computers, introduced in the early 1950s. It is considered a significant model in the evolution of computing technology. Here are some key points about the IBM 702: 1. **Model Introduction**: The IBM 702 was introduced in 1953 and was designed primarily for scientific and business applications.
In the context of physics, particularly in the theory of relativity, a four-vector is a mathematical object that extends the concept of vectors as used in three-dimensional space to four-dimensional spacetime. Four-vectors are crucial because they incorporate both spatial and temporal components, allowing for a unified description of relativistic effects.
United Nations Security Council Resolution 1985, adopted on June 31, 2011, recognizes the commitment of the Democratic Republic of the Congo (DRC) to promote democracy and holds an important position in addressing the challenges faced by the country. The resolution calls for the strengthening of national authorities and respect for human rights.
Ford Seattle-ite XXI is a concept car that was introduced by Ford in the early 2000s. It was designed as a futuristic vision of urban transport, specifically aimed at addressing the needs of city commuting. The vehicle showcased innovative features and technologies that were intended to be environmentally friendly and efficient for urban environments. The design of the Ford Seattle-ite XXI emphasized compactness and maneuverability, making it suitable for crowded city streets.
The Inhour equation is a formula used in nuclear engineering, particularly in the context of reactor kinetics and neutron diffusion. It characterizes the relationship between the neutron flux in a nuclear reactor and the reactor's reactivity, typically under steady-state or slightly perturbed conditions.
The Integral Fast Reactor (IFR) is a type of advanced nuclear reactor that was developed in the 1980s and 1990s at the Idaho National Laboratory in the United States. The IFR is notable for several key features: 1. **Fast Neutron Spectrum**: The IFR uses fast neutrons (rather than thermal neutrons, as in conventional reactors) for fission. This allows for more efficient use of fuel, particularly for plutonium and other actinides.
Small modular reactors (SMRs) are a category of nuclear reactors that have a smaller physical footprint compared to traditional large nuclear reactors and can be constructed and deployed in a modular fashion. These designs often aim to enhance safety, reduce costs, and allow for flexible deployment in various locations. Here’s a summary of some notable SMR designs: 1. **NuScale Power Module**: - Develops a light-water reactor design. - Each module has a capacity of about 60 MW.
Santa Susana Field Laboratory (SSFL) is a former industrial research and development facility located in the hills near Simi Valley, California. Established in the 1940s, SSFL was primarily used for the testing and development of rocket engines and nuclear research by various organizations, including NASA and the Boeing Company. Over the decades, it became a site for various key aerospace and defense projects.
Seversk State Technological Academy (SSTA) is a higher education institution located in Seversk, Russia. It focuses on engineering and technology education and is known for providing specialized training in areas such as nuclear power, materials science, and other technical fields. The academy offers a range of undergraduate and postgraduate programs and is involved in research and development activities, particularly in industries related to nuclear technology and energy.
Fuzzy differential inclusion is a mathematical concept that extends ordinary differential equations (ODEs) to account for uncertainty and imprecision, commonly represented by fuzzy sets or fuzzy logic. In classical differential equations, the solutions can be precisely defined under specific conditions. However, in many real-world applications, systems are subject to uncertainty or vagueness that cannot be captured by traditional methods.
United Nations Security Council Resolution 2270 was adopted on March 2, 2016, in response to North Korea's nuclear tests and ballistic missile launches, particularly a nuclear test conducted on January 6, 2016, and the subsequent missile launches. This resolution imposed a series of sanctions aimed at curtailing North Korea's nuclear weapons program and enforcing compliance with previous resolutions regarding its nuclear and ballistic missile activities.
Lists of nuclear reactors refer to compilations of operational, under-construction, and decommissioned nuclear reactors around the world. These lists can be categorized based on various criteria, including: 1. **Geographic Location**: Many lists organize reactors by country, such as the United States, France, Japan, and others, detailing the number of reactors and their specific locations.
A loss-of-pressure-control accident refers to an incident where there is a significant drop in pressure within a system that is supposed to maintain a specific pressure level, typically in industrial, chemical, or nuclear facilities. This loss of pressure can lead to various hazardous situations, including the uncontrolled release of gases or liquids, equipment failure, or even explosions. In many industrial processes, maintaining pressure is crucial for safety and operational efficiency.
