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...

Trends in the annual flux of sulfate and nitrate in a new ice core collected at an elevation of 3017 m on Eclipse Icefield, 45 km northeast of Mt. Logan were examined to determine the effect of anthropogenic activity on precipitation chemistry in the remote northwest North American midtroposphere. The annual flux of both sulfate and nitrate at Eclipse began increasing in the 1940s, demonstratin...

The Kieker framework offers features to monitor and to analyse the runtime behaviour of software systems. In this paper, we propose an associated Eclipse plugin to ease the usage of Kieker for novice users and to enable the profiling in the Eclipse environment. The monitoring part of the plug-in enables the automatic integration and configuration of the monitoring via an integrated UI. In this ...

Mueller, Frank. M.S., Purdue University, May, 2004. Penumbra: Enhancing Eclipse for Introductory Programming. Major Professor: Antony L. Hosking. In recent years, Java has become the most popular programming language for introductory programming courses; however, there has been a lack of a good Java development environment for novice computer science students. We decided to adapt Eclipse for te...

Eclipse is an open and extensible integrated development environment that allows third-party developers to integrate their plug-ins (tools) deeply with features shipped with the environment. Building a plug-in requires a developer to use Eclipse as a framework, extending and implementing classes in the Eclipse API, and calling appropriate methods on Eclipse objects using appropriate protocols. ...

This paper describes the design, construction, and performance analysis of the Eclipse, a redundantly actuated six-degree-of-freedom parallel mechanism intended for rapid machining. The Eclipse is a compact mechanism capable of performing five-face machining in a single setup while retaining the advantages of high stiffness and high accuracy characteristic of parallel mechanisms. We compare num...
