A sampler was developed to collect porewater from permeable (sandy) sediments during manned-submersible operations. The sampler uses vacuum (or atmospheric-pressure) reservoirs to draw porewater into a sediment probe and then into inline sample loops. The sampler is relatively inexpensive, easy to construct, and selfcontained, operating without an external power supply. The sample-loop/reservoi...

Combustion sampling for toxicological assessment often requires that large (greater than 100 mg) lots of complex organic mixtures of wide volatility range be rapidly recovered from high temperature gases without contamination. A new sampler, meeting these criteria for studies of public health interest, has been developed and demonstrated. The device provides high sampling rates and intimate con...

Lattice-based cryptography is one of the most promising areas within post-quantum cryptography, and offers versatile, efficient, and high performance security services. The aim of this paper is to verify the correctness of the discrete Gaussian sampling component, one of the most important modules within lattice-based cryptography. In this paper, the GLITCH software test suite is proposed, whic...

The problem of sampling proper q-colorings from uniform distribution has been extensively studied. Most of existing samplers require q ≥ α∆+ β for some constants α and β, where ∆ is the maximum degree of the graph. The problem becomes more challenging when the underlying graph has unbounded degree since even the decision of q-colorability becomes nontrivial in this situation. The Erdős-Rényi ra...

The Gibbs sampler, being a popular routine amongst Markov chain Monte Carlo sampling methodologies, has revolutionized the application of Monte Carlo methods in statistical computing practice. The performance of the Gibbs sampler relies heavily on the choice of sweep strategy, that is, the means by which the components or blocks of the random vector X of interest are visited and updated. We dev...

Designers can simulate thousands, if not millions, of design alternatives more cheaply and quickly than ever before with today’s computing power; however, the resulting data can overwhelm designers without proper tools to support multi-dimensional data visualization. In this paper, we discuss the use of a multi-dimensional data visualization tool and visual steering commands which allow designe...
