Aims. We present VRi photometric observations of the quadruply imaged quasar HE0435-1223, carried out with the Danish 1.54 m telescope at the La Silla Observatory. Our aim was to monitor and study the magnitudes and colors of each lensed component as a function of time. Methods. We monitored the object during two seasons (2008 and 2009) in the VRi spectral bands, and reduced the data with two i...

Qualitative simulation interpreted by the use of functional labels to identify significant system behaviour has been shown to be a useful technique for automating design analysis tasks such a Failure Modes and Effects Analysis. However, increasing sophistication of the systems to be analysed means that it is becoming increasingly important that the correct timing of these system functions be in...

The simultaneous generation of steam and power, which is commonly referred to as cogeneration, has been adopted by many sugar mills in India to overcome the power shortage. It becomes an increasingly important source of income for sugar factories. The problems faced by the sugar mill industry arise mainly due to failures of either the complete system or some specific components during the cogen...

A welding robot is an advanced piece of machinery in industry, especially in the field of industrial automation. As a complex system, it has a high failure probability because it manipulates, controls and performs complicated objects and tasks. Therefore, more attention has recently focused on the reliability of a welding robot. Reliability is very important because its performance will affect ...

Moist and temperate Caspian forests are associated with a diversity of soil types and topography.  Although, natural history and ecological attributes of the Caspian vegetation is well-documented, little is known about mycorrhizae of the Caspian (Hyrcanian) flora. Samples of herbaceous plant species were collected from 4 pre-determined altitudes (-13 upto about 1500m above sea level, appro...

We investigated how constraints imposed by the concurrent visual context modulate the effects of prior gender and action cues as well as of stereotypical knowledge during situated language comprehension. Participants saw videos of female or male hands performing an action and then inspected a display showing the faces of two potential agents (one male and one female face) as they listened to Ge...

In this report presents our experience with automating parts of the FMEA process using a model checker. As the case study a minepump control system is used, that prevents flooding in a mineshaft

This paper presents a multidisciplinary approach to privacy. The subject is examined from an ethical, social, and economic perspective reflecting the preliminary findings of the EU-funded research project PRESCIENT. The analysis will give a comprehensive illustration of the dimensions’ unique and characteristic features. This will build the basis for identifying overlaps and developing synerget...

PURPOSE Gamma Knife radiosurgery is a highly precise and accurate treatment technique for treating brain diseases with low risk of serious error that nevertheless could potentially be reduced. We applied the AAPM Task Group 100 recommended failure modes and effects analysis (FMEA) tool to develop a risk-based quality management program for Gamma Knife radiosurgery. METHODS A team consisting o...
