A Survey of the Trends in Facial and Expression Recognition Databases and Methods

open access: yes, 2015
Automated facial identification and facial expression recognition have been topics of active research over the past few decades. Facial and expression recognition find applications in human-computer interfaces, subject tracking, real-time security ...

Web-based visualisation of head pose and facial expressions changes: monitoring human activity using depth data

open access: yes, 2016
Despite significant recent advances in the field of head pose estimation and facial expression recognition, raising the cognitive level when analysing human activity presents serious challenges to current concepts.

Error Reporting in Parsing Expression Grammars

open access: yes, 2016
Parsing Expression Grammars (PEGs) describe top-down parsers. Unfortunately, the error-reporting techniques used in conventional top-down parsers do not directly apply to parsers based on Parsing Expression Grammars (PEGs), so they have to be somehow ...

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population

open access: yesPopulation Ecology, EarlyView.
This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...

How Censorship in China Allows Government Criticism but Silences Collective Expression

open access: yesAmerican Political Science Review, 2013
We offer the first large scale, multiple source analysis of the outcome of what may be the most extensive effort to selectively censor human expression ever implemented. To do this, we have devised a system to locate, download, and analyze the content of

Combining transient dynamics and logistic‐asymptotic growth to study the recovery of two seabird populations after rat eradication

open access: yesPopulation Ecology, EarlyView.
This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Noise Pollution Prediction in a Densely Populated City Using a Spatio-Temporal Deep Learning Approach

open access: yesApplied Sciences
Noise pollution in densely populated urban areas is a major issue that affects both quality of life and public health. This study explores and evaluates the application of deep learning techniques to predict urban noise levels, using the city of Madrid ...
