A chromium electroplating bath with the ability to produce homogenous mist was used to evaluate parameters influencing hexavalent chromium (Cr+6) mist sampling methods. The results of 48 Cr+6mist samples collected using the U.S. National Institute for Occupational Safety and Health method 7600...

OBJECTIVES To explore the effects of various factors related to the industry, the contaminant, and the period and type of sampling on long term declining trends in occupational exposure. METHODS Linear regression analyses were used to assess the relation between reductions in exposure and geographical location, industrial sector, type of contaminant, type of monitoring, carcinogenic classific...

There is a great demand for standardising biodiversity assessments in order to allow optimal comparison across research groups. For invertebrates, pitfall or flight-interception traps are commonly used, but sampling solution differs widely between studies, which could influence the communities collected and affect sample processing (morphological or genetic). We assessed arthropod communities w...

CONTENTS We investigate in greater detail a sampling formula given by the 1 . Introduction fjrst author for functions whose spectrum lies in a Cantor set K of 2. Asymptotic Behavior of the Sampling Function a special type introduced by Jorgensen and Pedersen, where the 3. Translates of the Sampling Function sampling set is extremely thin, and the sampling function is quite 4. The Sampling Formu...

We study primal-dual type stochastic optimization algorithms with non-uniform sampling. Our main theoretical contribution in this paper is to present a convergence analysis of Stochastic Primal Dual Coordinate (SPDC) Method with arbitrary sampling. Based on this theoretical framework, we propose Optimality Violation-based Sampling SPDC (ovsSPDC), a non-uniform sampling method based on Optimalit...

In this article, we study a class of biorthogonal sampling functions in the context of bandlimited wavelets, Meyer type wavelets. Originally raised in the construction of bandlimited wavelets, these sampling functions also possess a similar structure to the scaling functions of wavelets with adjustable bandwidth parameters. In addition, these sampling functions are infinite impulse response (II...

Various models and estimation procedures for estimating the number of species in a community are reviewed under the following sampling schemes: sampling by continuous-type of efforts, sampling by individuals, and sampling by quadrats (or multiple occasions). Applications and relevant software are briefly reviewed.
