Two mismatch functions (power or current) and three coordinates (polar, Cartesian and complex form) result in six versions of the Newton–Raphson method for the solution of power flow problems. In this paper, five new versions of the Newton power flow method developed for single-phase problems in our previous paper are extended to three-phase power flow problems. Mathematical models of the load,...

Load scheduling is critical to the performance of parallel processing network devices. With the rapid development of multi-core technology, efficient load scheduling scheme optimized for multi-core network processors becomes increasingly important and motivates intensive research today. In this paper, we study the relationship between two canonical scheduling schemes, packet-level scheduler and...

The combustion processes and emission formation in pre and main chambers of a Lister 8.1 IDI diesel are simulated with the Computational Fluid Dynamics (CFD) code. The model includes spray atomization, mixture formation and distribution and subsequently the combustion processes and emissions formation modeling are carried out with considering of flow configurations in two chambers. A part load ...

This thesis studies an innovative working hydraulic system design for mobile applications. The purpose is to improve the energy efficiency and the dynamic characteristics compared to load sensing systems without increasing the complexity or adding additional components. The system analysed in this thesis is referred to as flow control. The fundamental difference compared to load sensing systems...

This paper presents a distributed load flow that can be implemented in decentralized control centres. This becomes essential for power system having geographically separated areas. The system is partitioned into two areas balancing the number of nodes in each area. This is done to balance the computational load on the system in each control center. The Boundary buses are treated as load buses a...
