Structural Layout Optimization Strategy Considering Assemblage
Transactions of the Korean Society of Mechanical Engineers A, 2006In the ground-structure-based topology optimization, beam elements are regarded to be rigidly connected to each other, and joints are assumed to have infinite stiffness. Thus the optimized topology of a structure is obtained according to the assumption of no joint effect, and the resulting structure should be manufactured in one piece if the joint ...

Structure and arrangement for loudspeaker assemblage
The Journal of the Acoustical Society of America, 1980A loudspeaker assemblage is made up of a group of cylindrical speaker housings, with a speaker mounted in each housing. A respective spacer in the form of a wedge block or angle sleeve is interposed between adjacent housings, so that housing end closures abut respective wedges. A flexible tension member passes through each speaker housing and spacer so

Structural ecosystem change in Holocene chironomid assemblages
2020<p>There is a growing trend in using structural analyses to investigate temporal changes in ecosystem system architecture. System architecture defines the organisation of taxa within a system and how this may affect system response to stress.

1998
This chapter addresses empirical facts about structure of local freshwater fish assemblages. The evolutionary (ultimate) or mechanistic (proximate, ecological) explanations for that structure are the focus of later chapters. In Chapter 1, I defined a local “assemblage” as the fishes that would be found together in one particular place or “locality ...

Hunter-gatherer adaptations and assemblage structure
Journal of Anthropological Archaeology, 1987Abstract There is a growing tendency to conceive of hunter-gatherer adaptations as points on a yardstick, with foragers at one end and collectors on the other. Such a view limits our perspective and may trap anthropologists into seeing these categories as steps in an evolutionary progression. It is more productive to think of human adaptation as an N-

Viral impacts upon marine bacterioplankton assemblage structure
Journal of the Marine Biological Association of the United Kingdom, 2006This study examined the relationship between viral infection and the richness, diversity and composition of bacterial assemblages in the water column. Viruses were enriched by ultrafiltration, added to water column incubation experiments at 15 locations in the North Atlantic, North Pacific, Gulf of Mexico and Southern California.

Structural Strength of Hollow Clay Tile Assemblages
Journal of the Structural Division, 1973Clay tile and wall assemblages were tested as compressive prisms with six types of tile units. Specimens were tested at eccentricity ratios of 0, 1/6, and 1/3. Wall column specimens were built in three heights for the 4-in. units (h/t=10, 20, 40) and in two heights for the 6-in. and 8-in. units (h/t=10, 20) and tested with eccentricity ratios of 0, 1/6,

Segregation structure in Odonata assemblages follows the latitudinal gradient
Oecologia, 2020Latitude is known to deeply affect life with effects generalizable into ecological rules; the increasing species diversity toward tropics is the most paradigmatic. Several hypotheses tested patterns of biotic interactions' intensity along latitude. Negative interactions (i.e.

Does microhabitat structure affect foliar mite assemblages?
Ecological Entomology, 20101. Habitat structure is an important factor influencing population dynamics and trophic organisation of terrestrial invertebrates. The phylloplane zone on vascular plant leaves is topographically complex, containing a multitude of microhabitats such as leaf hairs, lesions, and structural refugia such as domatia, which may modify interactions between ...

Ecology, 1990
The wet—forest stream fishes of Sri Lanka are segregated in ecological and morphological space. Suites of selected morphological attributes of the fishes were correlated with microhabitat and feeding ecology. Previous studies have shown that these fishes partition resources with pronounced complementarities along niche axes, a pattern consistent with ...
