	Aggregate (composite) (Site not responding. Last check: 2007-10-31)
		Aggregate is the component of a composite material used to resist compressive stress.
		This is because aggregate particles tend to have about the same dimensions in every direction (that is, an aspect ratio of about one), so that aggregate composites do not display the level of synergy that fiber composites often do.
		In glass-ceramics, the aggregate is often chosen to have a negative coefficient of thermal expansion, and the proportion of aggregate to matrix adjusted so that the overall expansion is very near zero.

	Sun Java Center J2EE Patterns
		Aggregation combines inter-related persistent objects into a single entity bean, thus drastically reducing the number of entity beans required by the application.
		Since the Aggregate Entity is the coarse-grained object, the entity bean expresses and manages all relationships between the coarse-grained object and the dependent objects.
		Using the Aggregate Entity pattern, the dependent objects are aggregated in to a single entity bean eliminating all inter-entity bean relationships.

	Aggregate (composite) (Site not responding. Last check: 2007-10-31)
		Aggregate composites tend to be much easier to fabricate, and much more predictable in their finished properties, than fiber composites.
		Perhaps the most accessible examples of this are composites with an organic matrix and ceramic aggregate, such as asphalt concrete ("tarmac") and filled plastic (i.e., Nylon mixed with powdered glass), although most metal matrix composites also benefit from this effect.
		In-situ aggregate formation: Many micro-composites form their aggregate particles by a process of self-assembly.

	Concrete structural member and method for manufacture thereof - Patent 4774045
		Since the aggregate 3 is spread on the concrete layer 2 while the concrete layer 2 is still in its uncured state as described above, part of the aggregate is embedded in the concrete layer and the individual grains of the aggregate 3 protruding from the surface of the concrete layer entrap gaps therebetween.
		Otherwise, the composite concrete layer may be placed in a tightly sealed container and then this container evacuated until the capillary pores in the concrete layer are vacuumized and, thereafter, the composite concrete layer impregnated with the monomer.
		This aggregate layer which is impregnated with the polymer forms an extremely large boundary surface area with the concrete 7 owing to the rugged surface of the aggregate.

	ESRI,Guide for Using Diffusion Indexes and Composite Indexes
		The diffusion index and the composite index of business cyclical indicators are summary measures designed to facilitate the analysis and forecast of business cycles by combining the behavior of a group of economic indicators that represent widely differing activities of the economy, such as production and employment, and that correspond closely to turning points.
		The composite percent change is the sum of the mean of the trend of each series (aggregate mean percent change) and the mean of percent changes normalized by the interquartile range (composite normalized percent change of interquartile range) multiplied by the mean of the interquartile range (composite interquartile range).
		Composite indexes calculated in the new method are released at preliminary release for October 2004.

	Composite Study Speed
		The latest version of the Composite study function uses a new method for finding the points from each study with markedly faster results. For example, a large Composite study using five component studies that took over 30 hours in the earlier version, now runs in approximately 90 seconds.
		You may notice differences in the results for a study run under both the original Composite function and the new version. These differences result from a refinement in the process used for selection the points from each study.
		The earlier version of the Composite study searched the entire region around each point, all the way to the next point in each direction. In this example, that means the value assigned to the target point in the center of the diagram would be 30dBu, the maximum value of the points being considered.

	Best practices for using composite baselines in UCM
		Because composite baselines aggregate baselines from several components, it can be more difficult to make small, isolated changes in an integration stream, such as those that are needed to address stabilizing a release as it approaches a milestone.
		The composite baselines can be used to represent major subsystems in the product or, in the simplest case, a project can consolidate all of its baselines into a single component, which it recommends and delivers to follow-on projects.
		Composite baselines provide the capability to represent complex subsystems using a single identifier, and retain the flexibility and control of managing the lower-level components and subsystems independently.

	Wholes & System Composition Levels
		A concrete or material aggregate, on the other hand, is a compound thing, the components of which are not coupled, linked, connected, or bonded, such as a field constituted by two superposed fields, a celestrial constellation, and a random sample of a biological population.
		The composition of a system is the set of its components; the environment, the set of items with this it is connected; and the structure, the relations among its components as well as among these and the enviroment.
		And the composition of a school is the union of its staff and pupils; the environment is the natural and social mileu, and the structure consists of the relations of teaching and learning, managed and being managed, and others.

		Aggregation and composition are used to indicate whole-part relationships, and by definition, the “part” end cannot be aggregate.
		Composition (more correctly called composite aggregation) is used where there is a whole-part relationship that is one-to-one or one-to-many, and the lifetime of the part is inextricably tied to the lifetime of the whole.
		Aggregation and composition are used to indicate whole-part relationships, and by definition can only apply to binary associations between artifacts.

	The Use of Solid Waste Materials as Fine Aggregate Substitutes in Cementitious Concrete Composites
		For example, it was believed that the presence of crushed glass in aggregates tends to produce unworkable concrete mixtures, and that the high alkali content of such aggregates would affect the long-term durability and strength of the composite.
		An exception to this conclusion was the case of adding 20 percent glass aggregate substitute where the value of (f'c) for this concrete composite was comparable to that of the control one.
		It is to be noticed that the three concrete composites (containing 5 and 20 percent glass aggregate as well as the one containing 5 percent plastics aggregate) have the higher (R) values than the control composite.

	Fiber-reinforced recycled crushed concrete as a stabilized base course for highway pavements
		The aggregate from both sources meets CA06 specifications for coarse aggregate, and the grain size distributions are comparable to aggregates typically used as base course materials (11).
		This study was aimed toward evaluating the potential for a cementitious composite material consisting of recycled concrete aggregate, low quantities of cement and fly ash, and a modest amount of fibers to be used as a base course for flexible highway pavements.
		Results indicate that a recycled aggregate, stabilized with as little as 4% cement and 4% fly ash and reinforced with 4% by weight (1% by volume) of hooked-end steel fibers develops sufficiently high compressive, split tensile, and flexural strengths to be categorized as a high quality base course material.

		Composite: the whole (or composite) has a relationship to other entities which are its parts.
		Once a part is separated from the composite, the composite no longer has a relationship to the part.
		Aggregate: the whole (or aggregate) has a relationships to other entities which are its parts.

	Use of Fiber-Reinforced Soil-Cement or Recycled Aggregate for Pavement Base Course
		The goal of this research is to evaluate the benefits of a new composite material which exhibits the desirable mechanical properties of both soil-cement and full-depth asphalt while minimizing the cost and maximizing performance and resource conservation.
		Since the contribution of fibers to the strength of a cement-aggregate composite is believed to depend mainly on the fiber-matrix bond strength, the contribution of fibers to such relatively low strength composite materials prepared with low water-cement contents may be substantial in certain instances.
		While plain soil-cement and stabilized base courses with high quality aggregate are certainly not new, little is known about the effectiveness of lean mixes of compactable recycled aggregate and cement, including the bond that occurs between new cement and crushed Portland cement concrete or asphalt concrete.

	Measuring Changes in Energy Efficiency for the Annual Energy Outlook 2002
		A measure of end-use efficiency that is constructed by first aggregating the lighting output and energy consumption from all lighting technologies and then calculating end-use efficiency as the ratio of total lumens provided to total energy consumption.
		The other index, the “Aggregated Light Duty Vehicle Calculation,” is constructed using only aggregate miles per gallon for the combined LDV fleet, likely the more familiar calculation to most readers, as it tends to be more widely reported.
		This method reflects the composition shift to light trucks as a factor that decreases aggregate fleet miles per gallon and thus offsets some of the efficiency increases.

	SAP Design Guild -- Next Generation Applications - What Are They?
		Before taking a closer look at next generation applications – termed composite or cross applications (and called xApps by SAP) –, let's first examine the market needs that fostered their emergence, and take a look at the "traditional" application types that no longer fulfill these needs.
		Composite applications are composite as they integrate various existing applications.
		Composite applications help to empower teams by enabling ad-hoc team collaboration, both synchronous (for example, chat, instant messaging, application sharing), and asynchronous (for example, calendar, bulletin boards, threaded discussions, ratings, feedback).

	Descriptor Concepts
		Two objects–a source (parent or owning) object and a target (child or owned) object–are related by aggregation if there is a strict one-to-one relationship between them, and all the attributes of the target object can be retrieved from the same data source representation as the source object.
		This lets you configure an aggregate mapping (see "Configuring a Relational Aggregate Object Mapping") to associate data members in the target object with fields in the source object's underlying database tables.
		In EJB 3.0, an aggregate is known as an embeddable.

	Configuring a Relational Descriptor as a Class or Aggregate Type
		Aggregate descriptors do not define a table, primary key, or many of the standard descriptor options as they obtain these from their owning descriptor.
		If you want to configure an aggregate mapping to associate data members in a target object with fields in a source object's underlying database tables (see "Configuring a Relational Aggregate Collection Mapping" and "Configuring a Relational Aggregate Object Mapping"), you must designate the target object's descriptor as an aggregate.
		Although the attributes of a target class are not mapped directly to a data source until you configure an aggregate object mapping, you must still specify their mapping type in the target class's descriptor.
