Phase Morphology and Chemorheology during Curing of Polyethersulfone/Bismaleimide Multi-phase System
Journal of Aeronautical Materials, 2018 Curing characteristic of bismaleimide (BMI)/polyethersulfone (PES) multi-phase systems was studied by differential scanning calorimetry (DSC) using the non-isothermal method under different heating rates.

Tellus A: Dynamic Meteorology and Oceanography, 2001 State estimation is an important factor in the production of accurate forecasts. Great effort isexpended in reducing the noise inherent in observations, to produce a ‘‘best’’ estimate of thetrue system state. But noisy observations necessitate a probabilistic, not a deterministic,approach to state estimation.

Profiling instances in noise reduction [PDF]
Knowledge-Based Systems, 2012 The dependency on the quality of the training data has led to significant work in noise reduction for instance-based learning algorithms. This paper presents an empirical evaluation of current noise reduction techniques, not just from the perspective of their comparative performance, but from the perspective of investigating the types of instances that

Quantum noise reduction techniques in KAGRA [PDF]
Eur. Phys. J. D, 74, 10 (2020), 2019 KAGRA is the first large-scale gravitational-wave detector with cryogenic test masses. Its target sensitivity is limited mostly by quantum noise in the observation frequency band owing to the remarkable reduction of thermal noise at cryogenic temperatures.

Composite Test inclusive of Benfords Law, Noise reduction and 0-1 Test for effective detection of Chaos in Rotor-Stator Rub [PDF]
Nonlinear Dynamics, 2021, 2021 Segregating noise from chaos in dynamic systems has been one of the challenging work for the researchers across the globe due to their seemingly similar statistical properties. Even the most used tools such 0-1 test and Lyapunov exponents fail to distinguish chaos when signal is mixed with noise.

Study on Noise Reduction with Paving Different Low Noise Pavement Materials
Applied Sciences, 2021 This paper evaluates the amount of noise reduction when using different pavement materials in two adjacent lanes, where the close-proximity (CPX) method is introduced to analyze the tire/road noise before and after pavement maintenance.

Noise Reduction by Barriers [PDF]
The Journal of the Acoustical Society of America, 1973 A literature review is prepared to summarize the present state of knowledge concerning the field performance of barriers, with particular reference to screen-type barriers on finite impedance ground, to barriers of finite thickness, to right-angle wedges, to multiple barriers, and to effects of wind.
