Composite Hypothesis Tests for Detection of Modeling Misspecification

IEEE Transactions on Signal Processing, 2022
The performance of model-based signal processing inference methods may significantly degrade due to model errors. Thus, detection of model misspecification (MM) is essential in many applications. One of the most prominent MM detection approaches is based

Investigating the performance-related properties of crumb rubber modified bitumen using rheology-based tests

International Journal of Pavement Engineering, 2020
In recent years, crumb rubber (CR) has become an attractive option to modify bitumen. In this research, a set of Dynamic Shear Rheometer (DSR) tests were used were used to gauge the effect of two types of CR on different rheological and mechanical ...

Slow crack growth resistance of modern PA-U12 grades measured by cyclic cracked round bar tests and strain hardening tests

, 2020
A critical failure mechanism in long-term applications of plastic structures, such as piping systems, is considered to be crack initiation and subsequent Slow Crack Growth (SCG).

Characteristics, high temperature wear and oxidation behavior of boride layer grown on nimonic 80A Ni-based superalloy

Surface & Coatings Technology, 2021
Nickel-based superalloy Nimonic 80A was pack-borided in a solid medium at temperatures of 850 °C and 950 °C for 2 h and 4 h using silicon-free boriding powders.

The role of MVU estimator and CRB in binary composite hypothesis test

2009 IEEE International Symposium on Information Theory, 2009
This work presents a new perspective to the relationship between the composite binary hypothesis test and the estimation of its unknown parameters, i.e. the Uniformly Most Powerful (UMP) test and the Minimum Variance and Unbiased Estimator(MVUE). We show that for the one-sided binary composite hypothesis test, if the UMP test exists, it is nothing but ...

Microstructure and corrosion behaviour of WC/NiCrBSi coatings by vacuum cladding

Materials Science and Technology, 2022
In this work, the WC-NiCrBSi and in-situ synthesised WC (IWC)-NiCrBSi coatings were successfully fabricated on SS 316 L using vacuum cladding process to investigate the WC-reinforced NiCrBSi alloy by the two methods.

Tribological behaviour of pulsed magnetron sputtered CrB2 coatings examined by reciprocating sliding wear testing against aluminium alloy and steel

Surface and Coatings Technology, 2008
Among the number of attractive properties that transition-metal diborides (TiB2, CrB2, etc.) possess, high resistance to wear and chemical inertness are the most important when considering diboride coatings for dry machining of nonferrous materials, such as aluminium and its alloys.

Microstructural, wear and corrosion characteristics of boronized AISI 904L superaustenitic stainless steel

, 2021
AISI 900 series stainless steels are considered as low-cost alternatives to nickel-based superalloys used for highly corrosive environments. However, in terms of mechanical properties, they have average strength and hardness similar to other austenitic ...
