The greatest variability in both shear strength and roughness exists for joint samples with smaller size, which underscores the necessity of performing representative sampling. This study aims to ...

Large environmental health studies are increasing demand for reliable and unobtrusive methods to measure exposure. Innovation in passive air sampler design has the potential to address this need for ...

Accurate forest volume estimation is crucial for sustainable forest management, but the most commonly used methods often rely on models that may not always be applicable across different tree species ...

なぜ古典的変数サンプリングではゼロやマイナスが問題にならないのか、そしてPPSとは何が違うのか。その最大の理由は、「何を1単位として数えているか（サンプリング単位＝Sampling Unitの違い）」にあります。 非常にわかりやすい「くじ引き」のイメージ ...

A research team has developed a novel direct sampling method based on deep generative models. Their method enables efficient sampling of the Boltzmann distribution across a continuous temperature ...

The method of systematic random sampling (METHOD=SYS) selects units at a fixed interval throughout the sampling frame or stratum after a random start. PROC SURVEYSELECT chooses the first unit randomly ...
