Quaternary rupture of a crustal fault beneath Victoria, British Columbia, Canada [PDF]

open access: yes, 2017
The seismic potential of crustal faults within the forearc of the northern Cascadia subduction zone in British Columbia has remained elusive, despite the recognition of recent seismic activity on nearby fault systems within the Juan de Fuca Strait.

Multiband Comparative Study of Optical Microvariability in RL vs. RQ Quasars [PDF]

open access: yes, 2009
We present the results of an optical multi-band (BVR) photometric monitoring program of 22 core-dominated radio-loud quasars (CRLQs) and 22 radio-quiet quasars (RQQs). The aim was to compare the properties of microvariability in both types of quasars. We

Optical Microvariability in Quasars: Spectral Variability [PDF]

open access: yes, 2010
We present a method that we developed to discern where the optical microvariability (OM) in quasars originates: in the accretion disk (related to thermal processes) or in the jet (related to non-thermal processes).

One-Counter Automata with Counter Observability [PDF]

open access: yes, 2016
In a one-counter automaton (OCA), one can produce a letter from some finite alphabet, increment and decrement the counter by one, or compare it with constants up to some threshold.

Bending Characteristics of Foldable Touch Display Panel with a Protection Structure Design

open access: yesAdvances in Materials Science and Engineering, Volume 2015, Issue 1, 2015., 2015
The study proposes and demonstrates an enhancement of a touch display panel (TDP) through a polymer‐based protection structure to achieve higher bendability and reliability. The bending performance of the TDP without or with the protection structure designs is addressed using three‐dimensional geometry‐nonlinear finite element analysis and mechanical ...

Stability, instability and complex behavior in macrodynamic models with policy lag

open access: yesDiscrete Dynamics in Nature and Society, Volume 5, Issue 4, Page 281-295, 2000., 2000
We construct simple macrodynamic models with policy lag by means of mixed difference and differential equations, and study how lags in policy response affect the macroeconomic (in)stability. Local dynamics of the prototype model are studied analytically, and the global dynamics of the prototype and the extended models are studied by means of numerical ...

The village and the city: a diagnostic study of the spatial embedding patterns in villages absorbed by cities in Bahrain [PDF]

open access: yes, 2009
During the growth of cities villages are frequently absorbed into the fabric of that conurbation. But what are the consequences of this? To what extent and how well do these villages become part of the overall fabric of the city?

Time delay of SBS 0909+532

open access: yes, 2006
The time delays between the components of a lensed quasar are basic tools to analyze the expansion of the Universe and the structure of the main lens galaxy halo.
