An approach to design and implement the control function of LD (Ladder Diagram) in the hydropower simulation system based on all paths searching algorithm is proposed in this paper. LD is widely used as a programming language for PLC (Programmable Logic Controller), but it doesn’t be executed automatically in the hydropower simulation system which is a software system, and there is no compiler ...

Three-body decay functions in time-like parton branching are calculated using the jet calculus to the next-to-leading logarithmic (NLL) order in perturbative quantum chromodynamics (QCD). The phase space contributions from each of the ladder diagrams and interference diagrams are presented. We correct part of the results for the three-body decay functions calculated previously by two groups. Em...

The proton spin dependent structure function g p 1 is analysed using the unified scheme incorporating both Altarelli-Parisi evolution and the double ln 2 (1/x) effects at low x. The latter are found to be very important in the region of x which can possibly be probed at HERA. Predictions for the polarized gluon distribution ∆G(x) at low x are also given. It has recently been pointed out that th...

The perturbative QCD predictions for the small x behaviour of the nucleon structure functions F2,L(x,Q 2) and g1(x,Q 2) are summarized. The importance of the double logarithmic terms for the small x behaviour of the spin structure function g1(x,Q 2) is emphasised. These terms correspond to the contributions containing the leading powers of αsln(1/x) 2 at each order of the perturbative expansion...

The paper presents modification of the method dedicated to a complex area decomposition of a set of logic functions whereas the altered method is dedicated to implement the considered logic circuits within FPGA structures. The authors attempted to reach solutions where the number of configurable logic blocks and the number of structural layer would be reasonably balanced on the basis of the min...

In the last 30 years various mathematical models have been used to identify the effect of component failures on the performance of a system. The most frequently used technique for system reliability assessment is Fault Tree Analysis (FTA) and a large proportion of its popularity can be attributed to the fact that it provides a very good documentation of the way that the system failure logic was...
