Construction Aggregate
Construction aggregate, or simply aggregate, is a broad category of coarse- to medium-grained particulate material used in construction. Traditionally, it includes natural materials such as sand, gravel, crushed stone. As with other types of aggregates, it is a component of composite materials, particularly concrete and asphalt. Aggregates are the most mined materials in the world,Introduction (1): What are Aggregates? « Herefordshire & Worcestershire Earth Heritage TrustIntroduction (1): What are Aggregates? « Herefordshire & Worcestershire Earth Heritage Trust, accessdate: March 23, 2017Define Aggregate at Dictionary.comaggregate accessdate: March 23, 2017 being a significant part of 6 billion tons of concrete produced per year. Aggregate serves as reinforcement to add strength to the resulting material. Due to the relatively high hydraulic conductivity as compared to most soil types, aggregates are widely used in drainage applications such as foundation and French drain ...

Aggregate Data
Aggregate data is high-level data which is acquired by combining individual-level data. For instance, the output of an industry is an aggregate of the firms’ individual outputs within that industry. Aggregate data are applied in statistics, data warehouses, and in economics. There is a distinction between aggregate data and individual data. Aggregate data refers to individual data that are averaged by geographic area, by year, by service agency, or by other means. Individual data are disaggregated individual results and are used to conduct analyses for estimation of subgroup differences. Aggregate data are mainly used by researchers and analysts, policymakers, banks and administrators for multiple reasons. They are used to evaluate policies, recognise trends and patterns of processes, gain relevant insights, and assess current measures for strategic planning. Aggregate data collected from various sources are used in different areas of studies such as comparative political ana ...

Aggregate Level Simulation Protocol
The Aggregate Level Simulation Protocol (ALSP) is a protocol and supporting software that enables simulations to interoperate with one another. Replaced by the High Level Architecture (simulation) (HLA), it was used by the US military to link analytic and training simulations. ALSP consists of: #ALSP Infrastructure Software (AIS) that provides distributed runtime simulation support and management; #A reusable ALSP Interface consisting of generic data exchange message protocols; and #Participating simulations adapted for use with ALSP. History In 1990, the Defense Advanced Research Projects Agency (DARPA) employed The MITRE Corporation to study the application of distributed interactive simulation principles employed in SIMNET to aggregate-level constructive training simulations. Based on prototype efforts, a community-based experiment was conducted in 1991 to extend SIMNET to link the US Army'Corps Battle Simulation (CBS)and the US Air Force'Air Warfare Simulation (AWSIM) The ...

Aggregate (composite)
Aggregate is the component of a composite material that resists compressive stress and provides bulk to the material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. Aggregates are generally added to lower the amount of binders needed and to increase the strength of composite materials. Sand and gravel are used as construction aggregate with cement to make concrete and increase its mechanical strength. Aggregates make up 60-80% of the volume of concrete and 70-85% of the mass of concrete. Comparison to fiber composites ''Aggregate composites'' are easier to fabricate, and more predictable in their finished properties, than '' fiber composites''. Fiber orientation and continuity can have a large effect, but can be difficult to control and assess. Aggregate materials are generally less expensive. Mineral aggregates are found in nature and can often be used with minimal processing. Not all composite materials i ...

Aggregate (geology)
In the Earth sciences, aggregate has three possible meanings. In mineralogy Mineralogy is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical mineralogy, optical) properties of minerals and mineralized artifact (archaeology), artifacts. Specific s ... and petrology, an aggregate is a mass of mineral crystals, mineraloid particles or Rock (geology), rock particles. Examples are Dolomite (rock), dolomite, which is an aggregate of crystals of the mineral dolomite (mineral), dolomite, and ''rock gypsum'', an aggregate of crystals of the mineral gypsum. Lapis lazuli is a type of rock composed of an aggregate of crystals of many minerals including lazurite, pyrite, phlogopite, calcite, potassium feldspar, wollastonite and some sodalite group minerals. In the construction industry, an aggregate (often referred to as a construction aggregate) is sand, gravel or crushed rock that has been mining, mined or Q ...

Aggregate Income
Aggregate income is the total of all incomes in an economy without adjustments for inflation, taxation, or types of double counting. Aggregate income is a form of GDP that is equal to Consumption expenditure plus net profits. 'Aggregate income' in economics is a broad conceptual term. It may express the proceeds from total output in the economy for producers of that output. There are a number of ways to measure aggregate income, but GDP is one of the best known and most widely used. Measurement using GDP GDP stands for gross domestic product. GDP is a measure of the economic output of a country. It is usually defined as the total market value of goods and services produced within a given period after deducting the cost of goods and services used up in the process of production, but before allowances for depreciation. Most countries compile estimates of their GDP based on guidelines from the United Nations. GDP (Y) is the sum of consumption (C), investment (I), government spending ...

Aggregate Function
In database management, an aggregate function or aggregation function is a function where multiple values are processed together to form a single summary statistic. Common aggregate functions include: * Average (i.e., arithmetic mean) * Count * Maximum * Median * Minimum * Mode * Range * Sum Others include: * Nanmean (mean ignoring NaN values, also known as "nil" or "null") * Stddev Formally, an aggregate function takes as input a set, a multiset (bag), or a list from some input domain and outputs an element of an output domain . The input and output domains may be the same, such as for SUM, or may be different, such as for COUNT. Aggregate functions occur commonly in numerous programming languages, in spreadsheets, and in relational algebra. The listagg function, as defined in the SQL:2016 standard aggregates data from multiple rows into a single concatenated string. In the entity relationship diagram, aggregation is represented as seen in Figure 1 with a rectang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Skandha
' (Sanskrit) or (Pāḷi) means "heaps, aggregates, collections, groupings, clusters". In Buddhism, it refers to the five aggregates of clinging (), the five material and mental factors that take part in the perpetual process of craving, clinging and aversion due to Avijja. They are also explained as the five factors that constitute and explain a sentient being's person and personality, but this is a later interpretation in response to ''Sarvastivada, Sarvāstivādin'' essentialism. The 14th Dalai Lama subscribes to this interpretation. The five aggregates or heaps of clinging are: # form, sense objects (or material image, impression) () # sensations (or feelings of pleasure, pain, or indifference (both bodily and mental), created from the coming together of the senses, sense objects, and the consciousness) () # perceptions (or the nature of recognizing ''marks'' — making distinctions) () # mental activity, formations, or perpetuations () # consciousness (or the nature o ...
