Some New Developments in Small Area Estimation
Small area estimation has received a lot of attention in recent years due to growing demand for reliable small area statistics. Traditional area-specific estimators may not provide adequate precision because sample sizes in small areas are seldom large enough. This makes it necessary to employ indirect estimators based on linking models. Basic area level and unit level models have been extensiv...
متن کاملGraph Reconstruction - Some New Developments
The reconstruction conjecture claims that every graph on at least three vertices is uniquely determined by its collection of vertex deleted subgraphs. Even though it is one of the foremost unsolved problems in Graph Theory, work on it has slowed down, may be due to the general feeling that existing techniques are not likely to lead to a complete solution. Here we give the results that have appe...
متن کاملSome new developments in continuous microperfusion technique.
Nine years ago we designed the prototype of a microperfusion pump for calibrated perfusions of tubular segments in vivo(l). The apparatus consists, in principle, of a metal pin whiclh is driven into the fluid-filled shaft of a micropipet. Since the base of this pipet is sealed, the fluid may escape with a constant flow rate only through the tip of the capillary. In the meantime many improvement...
متن کاملSome New Features and Developments at ANESTHESIOLOGY
FOR over 3 yr, ANESTHESIOLOGY has provided authors with an on-line method for checking the status of their submitted manuscripts. We know that nearly 90% of our authors utilize this system at some time during the peer review process. For roughly a year and a half, we have been encouraging authors to submit their manuscripts electronically via our Web site, diskette, or e-mail. By the end of 200...
متن کاملOn Some New Developments in Approximate Inverse Preconditioning
Some new developments of conjugation-based sparse approximate inverse preconditioners are considered in application to problems of solid and structural mechanics. A block version of the AINV algorithm and its stabilized modification are presented. The stabilized AINV algorithm, which in exact arithmetic is breakdown-free for any SPD matrix, is found to result in robust preconditioners even in d...
