Computational Complexity Theory
In theoretical computer science and mathematics, computational complexity theory focuses on classifying computational problems according to their resource usage, and explores the relationships between these classifications. A computational problem is a task solved by a computer. A computation problem is solvable by mechanical application of mathematical steps, such as an algorithm. A problem is regarded as inherently difficult if its solution requires significant resources, whatever the algorithm used. The theory formalizes this intuition, by introducing mathematical models of computation to study these problems and quantifying their computational complexity, i.e., the amount of resources needed to solve them, such as time and storage. Other measures of complexity are also used, such as the amount of communication (used in communication complexity), the number of logic gate, gates in a circuit (used in circuit complexity) and the number of processors (used in parallel computing).

Central Corneal Thickness
Glaucoma is a group of eye diseases that can lead to damage of the optic nerve. The optic nerve transmits visual information from the eye to the brain. Glaucoma may cause vision loss if left untreated. It has been called the "silent thief of sight" because the loss of vision usually occurs slowly over a long period of time. A major risk factor for glaucoma is increased pressure within the eye, known as intraocular pressure (IOP). It is associated with old age, a family history of glaucoma, and certain medical conditions or the use of some medications. The word ''glaucoma'' comes from the Ancient Greek word (), meaning 'gleaming, blue-green, gray'. Of the different types of glaucoma, the most common are called open-angle glaucoma and closed-angle glaucoma. Inside the eye, a liquid called aqueous humor helps to maintain shape and provides nutrients. The aqueous humor normally drains through the trabecular meshwork. In open-angle glaucoma, the draining is impeded, causing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colossal Carbon Tube
Colossal carbon tubes (CCTs) are a tubular form of carbon. In contrast to the carbon nanotubes (CNTs), colossal carbon tubes have much larger diameters ranging between 40 and 100 μm. Their walls have a corrugated structure with abundant pores, as in corrugated fiberboard, where the solid membranes have a graphite-like layered structure. CCTs have technologically attractive properties such as ultra light-weight, extremely high strength, excellent ductility and high conductivity - which make them possibly suitable for clothing. They are excellent (105 siemens per metre) electrical conductors, are 15 times stronger than the strongest carbon fiber (T1000), have 30 times the tenacity of Kevlar and are 224 times stronger than individual cotton fibers. The tubes exhibit an ultra low density comparable to that of carbon nanofoams. CCTs have a tensile strength of 7 GPa, and a high specific strength (tensile strength per density), and a breaking length of 6,000 km. This exceeds the ...

Cold Cathode
A cold cathode is a cathode that is not electrically heated by a Electrical filament, filament.A negatively charged electrode emits electrons or is the positively charged terminal. For more, see field emission. A cathode may be considered "cold" if it emits more electrons than can be supplied by thermionic emission alone. It is used in Gas discharge lamp, gas-discharge lamps, such as neon lamps, discharge tubes, and some types of vacuum tube. The other type of cathode is a hot cathode, which is heated by electric current passing through a Electrical filament, filament. A cold cathode does not necessarily operate at a low temperature: it is often heated to its operating temperature by other methods, such as the current passing from the cathode into the gas. Cold-cathode devices A cold-cathode vacuum tube does not rely on external heating of an electrode to provide thermionic emission of electrons. Early cold-cathode devices included the Geissler tube and Julius Plücker, Plucker ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal Pollution Mitigation
Coal pollution mitigation is a series of systems and technologies that seek to mitigate health and environmental impact of burning coal for energy. Burning coal releases harmful substances that contribute to air pollution, acid rain, and greenhouse gas emissions. Mitigation includes precombustion approaches, such as cleaning coal, and post combustion approaches, include flue-gas desulfurization, selective catalytic reduction, electrostatic precipitators, and fly ash reduction. These measures aim to reduce coal's impact on human health and the environment. The combustion of coal releases diverse chemicals into the air. The main products are water and carbon dioxide, just like the combustion of petroleum. Also released are sulfur dioxide and nitrogen oxides, as well as some mercury. The residue remaining after combustion, coal ash often contains arsenic, mercury, and lead. Finally, the burning of coal, especially anthracite, can release radioactive materials. Mitigation t ...

Certified Calibration Technician
The American Society for Quality (ASQ), formerly the American Society for Quality Control (ASQC), is a society of quality professionals, with more than 30,000 members, in more than 140 countries. History ASQC was established on 16 February 1946 by 253 members in Milwaukee, Wisconsin, with George D. Edwards as its first president. The organization was first created as a way for quality experts and manufacturers to sustain quality-improvement techniques used during World War II. In 1948, ASQC's Code of Ethics established standards for members to conduct their activities and business. Business writer Armand V. Feigenbaum served as president of the society in 1961–63. In 1997, the members of the organization voted to change its name from "American Society for Quality Control" to "American Society for Quality". Quality ASQ provides its members with certification, training, publications, conferences, and other services. ASQ is a founding partner of the American Customer Sa ...

Churches Conservation Trust
The Churches Conservation Trust is a registered charity whose purpose is to protect historic churches at risk in England. The charity cares for over 350 churches of architectural, cultural and historic significance, which have been transferred into its care by the Church of England. The Trust works to prevent any deterioration in the condition of the buildings in its care and to ensure they are in use as community assets. Local communities are encouraged to use them for activities and events and the buildings provide an educational resource, allowing children and young people to study history, architecture and other subjects. Most of the churches saved from closure are Grade I or Grade II* listed. Many are open to visitors as heritage sites on a daily basis and nearly 2 million people visit the Trust's churches each year. The majority of the churches remain consecrated, though they are not used for regular worship. History The trust was established by the Pastoral Measur ...
