This paper considers the problem of reduction of self-localization errors in multi-agent autonomous formations when only distance measurements are available to the agents in a globally rigid formation. It is shown that there is a relationship between different selections of anchors, agents with exactly known positions, and the error induced by measurement error on localization solution. This fa...

This paper studies distributed control of bearing-constrained multiagent formations using bearing-only measurements. In order to analyze bearing-constrained formations, we first present a bearing rigidity theory that is applicable to arbitrary dimensions. Based on the proposed bearing rigidity theory, we investigate distributed bearing-only formation control in arbitrary dimensions in the prese...

in this paper, bam postseismic deformations during 7 years after earthquake have been extracted using persistent scatterer interferometry technique. the time series are inverted for the afterslip distribution on an extension of the coseismic rupture. the estimated postseismic slip value is 20.45±0.38 cm. most of the postseismic displacement field can be explained in terms of fault slip. the res...

In an infusion test the apparent rate of cerebrospinal fluid (CSF) production is temporarily increased through injection of fluid directly into the CSF system with the result that CSF pressure rises, in theory to a new plateau average, and the change in pressure level gives a measure of resistance to CSF outflow and the rate of approach to the plateau gives information about cerebral compliance...

Colloidal-probe spherical indentation load-relaxation experiments with a probe radius of 3 μm are conducted on poly(ethylene glycol) (PEG) hydrogel materials to quantify their steady-state mechanical properties and time-dependent transport properties via a single experiment. PEG-based hydrogels are shown to be heterogeneous in both morphology and mechanical stiffness at this scale; a linear-har...

Phenomenological equations (with coeecients to be determined by speciied experiments) for the poroelastic behavior of a dual porosity medium are formulated and the coeecients in these linear equations are identiied. The generalization from the single porosity case increases the number of independent coeecients for volume deformation from three to six for an isotropic applied stress. The physica...
