The celebrated LAMBDA method has been widely used in GNSS for fixing integer ambiguities. For real time kinematic GNSS applications with high dimensions, the computational speed is crucial. In this paper a modified LAMBDA method (MLAMBDA) is presented. Several strategies are proposed to reduce the computational complexity. Numerical simulations show that MLAMBDA is (much) faster than LAMBDA.

Australian spiders of the genus Abstract. -Three species of the spider genus Physocyclus (P. calijbrnicus, P. enaulus. P, sp.) . SOC. 96:359-362. were karyotyped using an air-drying, Giemsa staining method. All chromosomes were metacentric, with males being 2n = 15 (N = 7 + XO) and females being 2n = 16. The karyotyping method resulted in slide preparations which were countable five years post-...

The quality of grouting and consolidation orifice pipe in water exploration drainage drilling is directly related to whether a large amount from holes can be successfully controlled. For with fissure within 3 m holes, difficult point drainage. By studying the principle segmented technology, casing installation construction technology technical parameters plugging, we have solved problem under c...

A heterotrophic semisolid medium was used with two sensitive assay methods, C(2)H(2) reduction and O(2)-dependent tritium uptake, to determine nitrogenase and hydrogenase activities, respectively. Organisms known to be positive for both activities showed hydrogenase activity in both the presence and absence of 1% C(2)H(2), and thus, it was possible to test a single culture for both activities. ...
