Large-Scale Structure from Wide-Field Surveys
In this introductory talk I give an elementary overview of the development, current status, and near term outlook for three probes of large scale structure; galaxy clustering, bulk flows and weak lensing observations. 1 The Paradigm for Structure Formation This meeting is largely concerned with the major observational expansion occurring in the field of wide-field cosmological surveys. These ad...
متن کاملA Variable Structure Observer Based Control Design for a Class of Large scale MIMO Nonlinear Systems
This paper fully discusses how to design an observer based decentralized fuzzy adaptive controller for a class of large scale multivariable non-canonical nonlinear systems with unknown functions of subsystems’ states. On-line tuning mechanisms to adjust both the parameters of the direct adaptive controller and observer that guarantee the ultimately boundedness of both the tracking error and tha...
متن کاملVisualizing a large-scale structure of production network by N-body simulation
Our recent study of a nation-wide production network uncovered a community structure, namely how firms are connected by supplier-customer links into tightly-knit groups with high density in intra-groups and with lower connectivity in inter-groups. Here we propose a method to visualize the community structure by a graph layout based on a physical analogy. The layout can be calculated in a practi...
متن کاملGeographical Variability as a Determinant of Large-scale Network Structure∗
It is a well-established result that the marginal probability of a social tie between two persons declines with geographical distance for a wide range of social relations (see, e.g., Bossard, 1932; Zipf, 1949; Festinger et al., 1950; Hägerstrand, 1967; Freeman et al., 1988; Latané et al., 1995; McPherson et al., 2001). While often regarded as a mere curiosity, others have argued that this relat...
متن کاملA Facile and Green Synthesis Route for the Production of Silver Nanoparticles in Large Scale
In the present work, a fast, green and simple synthesis method for the production of silver nanoparticles (AgNPs) is introduced. Silver nanoparticles are currently among the most widely used man-made nano materials, present in a wide range of consumer products. Green chemistry is characterized by careful planning of chemical synthesis of silver nanoparticles to reduce adverse outcomes. S...
