We present a filtering technique that can be applied to individual baselines of widebandwidth, wide-field interferometric data to geometrically select regions on the celestial sphere that contain primary calibration sources. The technique relies on the Fourier transformation of wide-band frequency spectra from a given baseline to obtain onedimensional “delay images”, and then the transformation...

In cooperative multiagent systems, coordinating the jointactions of agents is difficult. One of the fundamental difficulties in such multiagent systems is the slow learning process where an agent may not only need to learn how to behave in a complex environment, but may also need to account for the actions of the other learning agents. Here, the inability of agents to distinguish the true envir...

This report documents the program and the outcomes of Dagstuhl Seminar 15162 on “Software and Systems Traceability for Safety-Critical Projects”. The event brought together researchers and industrial practitioners working in the field of safety critical software to explore the needs, challenges, and solutions for Software and Systems Traceability in this domain. The goal was to explore the gap ...

Shared network testbeds rely on the ability to bring nodes to a known “clean” state, and to allow experimenters to customize the software installed on the nodes assigned to them. This is typically done by replacing the contents of the nodes’ disks with a clean disk image. Frisbee is designed for just this purpose. It is a fast, highly scalable system for creating, distributing, and installing d...

If we were to design a new scientific field with a clean slate perspective, what might be the outcome? The panelists have been working in various ways for the last few years on establishing a new domain of inquiry, Energy Informatics. The panel will address key questions that they think should be considered by those designing a new discipline. Specifically, they will address the following criti...

A variety of methods for audio-visual integration, which integrate audio and visual information at the level of either features, states, or classifier outputs, have been proposed for the purpose of robust speech recognition. However, these methods do not always fully utilize auditory information when the signal-to-noise ratio becomes low. In this paper, we propose a novel approach to estimate s...

In this paper we present a hierarchical method that decomposes a system into two subsystems, and restricts the interaction of the subsystems by means of an interface. We present definitions for two types of interfaces (represented as discrete-event systems (DES)), and define a set of interface consistency properties that can be used to verify if a DES is nonblocking and controllable. Each claus...

there is possibility of microbial contamination of any single-dose vials (sdvs), multiple-dose vials (mdvs) and admixtures (adxs) during the preparation and injection to the patients that could be resulted in bloodstream infection. the goal of this study was to investigate the microbial contamination of mdvs and sdvs after multiple use and adxs prepared by nursing staff in the treatment room ve...
