Exact methods for comparison of estimation strategies in survey sampling. [PDF]
, 2010 PhDMany strategies in survey sampling depend on large sample approximation formulae for design-based inference on finite population parameters, which are not valid for small samples. We develop an approach using matrix algebra to tackle many problems

Sliced Latin Hypercube Designs for Computer Experiments With Unequal Batch Sizes
IEEE Access, 2018 Latin hypercube designs are frequently used in estimating the mean output value of computer simulations given random environmental factors. Sliced Latin hypercube designs are designs that can be partitioned into a number of batches so that both the whole

A hardware prototype of wideband high‐dynamic range analog‐to‐digital converter
IET Circuits, Devices and Systems, 2023 Key parameters of analog‐to‐digital converters (ADCs) are their sampling rate and dynamic range. Power consumption and cost of an ADC are directly proportional to the sampling rate; hence, it is desirable to keep it as low as possible.
