Contact, the feature pool and the speech community : The emergence of Multicultural London English. [PDF]

, 2011
In Northern Europe’s major cities, new varieties of the host languages are emerging in the multilingual inner cities. While some analyse these ‘multiethnolects’ as youth styles, we take a variationist approach to an emerging ‘Multicultural London English’

Discriminant Feature Extraction for Centrifugal Pump Fault Diagnosis

IEEE Access, 2020
Raw statistical features can imitate the amplitude, average, energy and time, and frequency series distribution of a raw vibration signal. However, these raw statistical features are either not very sensitive to weak incipient faults or are unsuitable ...

Dial-a-Ride Problem With Meeting Point Feature Known-as Express-Pool

IEEE Access, 2021
This study extends a dial-a-ride problem by considering (1) Express-Pool and (2) Friend-Only. Uber provides an advanced feature called Express-Pool where passengers are willing to walk a short distance to be picked up and be dropped off somewhere close ...

Face image classification by pooling raw features [PDF]

Pattern Recognition, 2016
We propose a very simple, efficient yet surprisingly effective feature extraction method for face recognition (about 20 lines of Matlab codes), which is mainly inspired by spatial pyramid pooling in generic image classification. We show that, coupled with a linear classifier, features formed by simply pooling local patches over a multi-level pyramid ...

Feature Extraction of Laser Welding Pool Image and Application in Welding Quality Identification

IEEE Access, 2021
Most of the existing laser welding quality identification methods are post-weld identification or low-speed identification (Welding speed below 120 m/min).
