We propose DEVS-Driven Modeling Language (DDML), a graphical notation for DEVS modeling and an Eclipse-based graphical editor, Eclipse-DDML. DDML attempts to bridge the gap between expert modelers and domain experts making it easy to model systems, and capture the static, dynamic, and functional aspects of a system. At the same time, it unifies C-DEVS and P-DEVS models. DDML integrates excellen...

We present an approach to providing broad-based accessibility to graphical applications by employing the capabilities of the Eclipse development platform and aspect oriented programming (AOP) in a way that leverages the strengths of each. We describe the Eclipse platform and the advantages of AOP and contrast AOP with object oriented programming (OOP). Then, we discuss how to use of Eclipse fra...

HS0907+1902 was recently discovered to be one of a handful of deeply eclipsing dwarf novae with periods longward of the 2 – 3 hr ‘gap’. This paper presents orbit-resolved spectra and time series photometry of an eclipse. The apparent velocity amplitude of the M-dwarf secondary is K2 = 297 ± 15 km s . The phase of the radial velocities of the Hα emission line wings agrees accurately (for once) w...

While some commonly occurring error patterns in Java are addressed by static tools such as FindBugs[5], complex software systems are full of rules that developers must follow. These application-specific rules are often not expressed in any way other than code comments and often are not enforced, leading to hard-to-detect bugs later in the program execution. Eclipse represents one of the biggest...

We present the XMM-Newton X-ray eclipse lightcurve of the dwarf nova OY Car. The eclipse ingress and egress are well resolved for the first time in any dwarf nova placing strong constraints on the size and location of the X-ray emitting region. We find good fits to a simple linear eclipse model, giving ingress/egress durations of 30±3 s (∆φorb = 0.0055±0.0006). Remarkably this is shorter than t...
