The penalized profile sampler
The penalized profile sampler for semiparametric inference is an extension of the profile sampler method [9] obtained by profiling a penalized log-likelihood. The idea is to base inference on the posterior distribution obtained by multiplying a profiled penalized log-likelihood by a prior for the parametric component, where the profiling and penalization are applied to the nuisance parameter. B...
متن کاملA Simple Self-triggered Sampler for Nonlinear Systems
Self-triggered control is a promising aperiodic control paradigm that allows the design of resource-efficient control schemes. Several results were recently developed for self-triggered control of linear systems, but self-triggered control for nonlinear systems is still not well understood. Existing techniques are mainly limited to homogeneous or polynomial closed-loop systems that are inputto-...
متن کاملSimple inspection by tube.
New Appliances £DIRmAH 707 in length, and at its distal end has a tapering mount 0-236 in. (6 mm.) in length. At its proximal end there is a female Luer lock fitting, which can be firmly attached to a Luer or Luer lock syringe (see photograph). Our technique of primary operative cholangiography follows very closely that of Schulenburg (1966). Two points are worth mentioning. Firstly, if the sup...
متن کاملHigh-resolution pore-water sampling with a gel sampler
Sediment pore-water profiles were sampled at high resolution (millimeter scale) with a polyacrylamide gel probe. This simple procedure involves inserting a l-mm-thick gel held in a plastic probe into sediment. The gel reaches diffusive equilibrium in < l-2 h. For anions, the gel was sectioned, back-equilibrated into distilled-deionized water, and anions determined by high-performance liquid chr...
متن کاملA high - resolution pore water sampler for sandy sediments
In this paper, we present a new technique for collecting pore-water samples in coarseto fine-grained sandy sediments. We have used the technique both for in situ sampling and for pore-water extraction from sediment cores brought back to the laboratory, in both cases with a depth resolution as fine as 1 cm. The key device is a long, thin (;2 mm) stainless steel tube with a specially designed tip...
