Predictive Coordination in Two Level Hierarchical Systems
New optimization method, using Non-iterative coordination in multilevel systems is developed. Coordination with prediction is considered. Decision making for optimal resource allocation in a two levels system is worked out. Appropriate model for steady state optimization is derived. Analytical relations are given, which benefit the real time management of the two level control system. Index Te...
متن کاملTwo Optimization Methods for Raytracing Two Optimization Methods for Raytracing
Raytracing is a method to produce photo-realistic pictures. For each pixel of an image one ray is shot to nd the object, which determines the color of the pixel. Rays are also used to simulate shadows and reeections. Previously bounding volume hierarchies have been used to speed raytracing. A new method to speed the traversal of a bounding volume hierarchy is presented. Optimisation methods to ...
متن کاملTwo-level Hierarchical Scheduling Algorithm for Real-time Multiprocessor Systems
The Earliest Deadline First (EDF) scheduling algorithm has the least runtime complexity among joblevel fixed-priority algorithms for scheduling tasks on multiprocessor architectures. However, EDF suffers from suboptimality in multiprocessor systems. This paper proposes a new restricted migration-based scheduling algorithm for multiprocessor real-time systems, called Two-level Hierarchical Sched...
متن کاملA Two Level Approximation Technique for Structural Optimization
This work presents a method for optimum design of structures, where the design variables can he considered as Continuous or discrete. The variables are chosen as sizing variables as well as coordinates of joints. The main idea is to reduce the number of structural analyses and the overal cost of optimization. In each design cycle, first the structural response quantities such as forces, displac...
متن کاملTowards Robust Two-Level Methods For Indefinite Systems
Despite the fact that iterative solution techniques are recently gaining recognition among practitioners and finding their way into commercial software arena, the current state of the art in iterative methods remains unsatisfactory in many respects. Users of large production codes such as ANSYS, NASTRAN, ALGOR, SDRC, EMRC and ANSYS often observe many “bad” cases resulting from poorly conditione...
