First passage of stochastically dynamical system with fractional derivative and power-form restoring force under Gaussian excitation [PDF]

FME Transactions, 2014
First passage problem in a dynamical system with power-form restoring force and fractional derivative is studied in this paper. At first, the original system is transformed into an diffusion differential equation by way of generalized Van der Pol ...

To What Extent Do Australian Government Metrics Align With Indigenous and Non‐Indigenous Conceptualisations of Wellbeing? A Scoping Review of Wellbeing Frameworks

Australian Journal of Social Issues, EarlyView.
ABSTRACT Indigenous wellbeing theories offer potential to better measure social and cultural determinants. This scoping review aimed to identify the types of metrics used by the Australian government to assess wellbeing and evaluate the alignment of current frameworks against Indigenous and non‐Indigenous conceptualisations of wellbeing.

‘Shelter is a Dignity’: Rental Racism, Stress and Housing (In)justice

Australian Journal of Social Issues, EarlyView.
ABSTRACT Australia's private rental sector is in crisis, and culturally and racially minoritised renters face compounded harms through both covert and everyday direct forms of rental racism. Drawing on five community‐based focus groups in Melbourne (n = 37), the paper explores how racism manifests across the rental pathway and how it structures the ...

Barriers in impulsive antiperiodic problems

Electronic Journal of Qualitative Theory of Differential Equations, 2019
Some real world models are described by means of impulse control of nonlinear BVPs, where time instants of impulse actions depend on intersection points of solutions with given barriers.

Cohesion Without Consensus: Attitudinal Profiles of Social Cohesion in Australia

Australian Journal of Social Issues, EarlyView.
ABSTRACT Headline indicators of social cohesion in Australia have remained stable in recent years despite rising political polarisation and declining institutional trust worldwide. Yet recent protests and incidents of ethnically and politically motivated violence suggest that cohesion may be under strain. If cohesion is understood not as the pursuit of

Hepatic morphology and serum biochemical profile according to dry and rainy seasons in Pygocentrus nattereri (Characiformes: Serrasalmidae)

The Anatomical Record, EarlyView.
Abstract This study investigated the physiological and morphological adaptations of the liver of the carnivorous fish Pygocentrus nattereri (piranha) in response to seasonal variations (dry and rainy seasons) in the Brazilian Pantanal. The objective was to describe how the liver, a central organ in metabolic regulation, responds to environmental ...

Existence, uniqueness and other properties of the limit cycle of a generalized Van der Pol equation

Electronic Journal of Differential Equations, 2014
In this article, we study the bifurcation of limit cycles from the linear oscillator $\dot{x}=y$, $\dot{y}=-x$ in the class $$ \dot{x}=y,\quad \dot{y}=-x+\varepsilon y^{p+1}\big(1-x^{2q}\big), $$ where $\varepsilon$ is a small positive parameter ...

An Algorithm for Higher Order Hopf Normal Forms

Shock and Vibration, 1995
Normal form theory is important for studying the qualitative behavior of nonlinear oscillators. In some cases, higher order normal forms are required to understand the dynamic behavior near an equilibrium or a periodic orbit.
