The High-Energy Lightcurve Generator (HILIGT) is a new web-based1 tool which allows the user to generate long-term lightcurves of X-ray sources. It provides historical data and calculates upper limits from image in real-time. HILIGT utilizes twelve satellites, both modern missions such as XMM-Newton Swift, earlier facilities ROSAT, EXOSAT, Einstein or Ariel V. Together, this enables query 50 ye...

For a cosmological first-order electroweak phase transition, requiring no sphaleron washout of baryon number violating processes leads to lower bound on the strength transition. The velocity boundary between phases, so-called bubble wall, can become ultra-relativistic if friction due plasma particles is not sufficient retard wall's acceleration. This ``runaway'' should occur successful asymmetr...

Our aim is to maximize expected profit per item of a multi-stage production system by determining best adjustment points of the equipments used based on technical product specifications defined by designer. In this system, the quality characteristics of items produced should be within lower and higher tolerance limits. When a quality characteristic of an item either falls beneath the lower li...
