Design of a high SNR electronic heart sound sensor based on a MEMS bionic hydrophone
AIP Advances, 2019 Since most of the contact conduction type of heart sound sensors don’t take into account the acoustic signal attenuation problem caused by the heart sound signal transmitting to a sensor whose filling materials’ impedance is different to human soft ...

Dynamical Dorfman Testing with Quarantine
2022 56th Annual Conference on Information Sciences and Systems (CISS), 2022 We consider dynamical group testing problem with a community structure. With a discrete-time SIR (susceptible, infectious, recovered) model, we use Dorfman's two-step group testing approach to identify infections, and step in whenever necessary to inhibit infection spread via quarantines.

Dynamic Prioritization in Regression Testing [PDF]
2011 IEEE Fourth International Conference on Software Testing, Verification and Validation Workshops, 2011 Although used extensively in industry, regression testing is challenging from both a process management as well as a resource management perspective. In literature, proposed test case prioritization techniques assume a constant pool of test cases with non-changing coverage during the regression testing process, and therefore they work with a fixed ...

An optimal statistical testing policy for software reliability demonstration of safety-critical systems [PDF]
, 2002 When software reliability demonstration of safety-critical systems by statistical testing is treated as a Test, Analyse and Fix (TAAF) process, an optimal testing policy can be found, which maximises the probability of success of the whole process, over ...

Modal testing and FE model tuning of a lively footbridge structure [PDF]
, 2006 Despite huge advances in numerical modelling of civil engineering structures in recent decades, finite element models for footbridges should still be developed and used with caution when evaluating modal properties of these structures.

Dynamic Tunable Deflection of Radiation Based on Epsilon-Near-Zero Material
Photonics, 2023 Epsilon-near-zero nanoantennas can be used to tune the far-field radiation pattern due to their exceptionally large intensity-dependent refractive index. In this study, we propose a hybrid optical antenna based on indium tin oxide (ITO) to enable optical

Development of a Simplified Dynamic Testing Device for Turfed Sports Surfaces [PDF]
, 2011 The response of natural turf surfaces to loading changes with the force and loading rate applied. Quantification of surface behaviour to athlete loading is complicated by the lack of devices that replicate forces, stresses and loading rates of ...
