A high flux source of cold strontium atoms

We describe an experimental apparatus capable of achieving a high loading rate of strontium atoms in a magneto-optical trap operating in a high vacuum environment. A key innovation of this setup is a two dimensional magneto-optical trap deflector located after a Zeeman slower. We find a loading rate of 6x10^9/s whereas the lifetime of the magnetically trapped atoms in the 3P2 state is 54s.Comment: 12 pages, 16 figure

Effect of autumn and winter water-charging irrigation on water status of almond

The water status of almond was monitored during the vegetational season and autumn-winter period. The effect of autumn-winter water-charging irrigation on the development of almond and its productivity was studied. The highest level of productivity has been received at use of three vegetative and two water-charging irrigation in November and December

Safe automotive software

For automotive manufacturers and tier-1 suppliers, the upcoming safety standard ISO 26262 results in new requirements for the development of embedded electronics and software. In particular, the variety of driver assistance systems that autonomously influence the driving dynamics of a vehicle may have a high risk potential and require development in accordance with the normative guidelines. But especially for those systems whose function is typically not based solely on hardware but on complex software algorithms, safety certification can be very complex or even impossible. In this paper the problems of development of vehicle systems according to ISO 26262 are described. Finally an approach for a safety-oriented reference architecture is presented that introduces adaptive software safety cages. This architecture enables application of formal verification methods. Supported by multisensor data fusion this allows to reduce safety requirements for vehicle control systems
