Luminous Phenomena of Earthquakes: Observations and Theories
Over the past few years, different theories (piezoelectric, positive holes, friction-vaporization, exo-electron emission, tribo- or fracture electrification) have been presented for the interpretation of earthquake lights. Although these theories can interpret earthquake luminous, each suffer from particular problems. There are also ambiguities and questions about the location of the light, the...
متن کاملPriority queue classes with priority update
A limitation in the design of the interface of C++ standard priority queues is addressed. The use of priority queues in Dijkstra’s shortest path search algorithm is used as an example. Priority queues are often implemented using heaps. There is a problem, as it may be necessary to change the priority of an element while it is in the queue, but finding the element from within a heap is costly. T...
متن کاملImpact of priority levels on the efficiency of priority switching
The paper deals with a neural network controlled switch fabric with frame prioritization support. The impact of priority levels on the functionality and efficiency of this switch fabric was deeply investigated. The results of the studies related to the impact of the amount of priority levels are published in this paper. Key-Words: Hopfield neural network, switch fabric, prioritization, priority...
متن کاملOn priority queues with priority jumps
In this paper, we investigate a simplified head-of-the-line with priority jumps (HOL-PJ) scheduling discipline. Therefore, we consider a discrete-time single-server queueing system with two priority queues of infinite capacity and with a newly introduced HOL-PJ priority scheme. We derive expressions for the probability generating function of the system contents and the packet delay. Some perfor...
متن کاملMODELLING AND ANALYSIS OF A DISCRETE-TIME PRIORITY QUEUING COMPUTER NETWORK WITH PRIORITY JUMPS USING PROBABILITY GENERATING FUNCTIONS
Priority queues have a great importance in the study of computer communication networks in which different types of traffic require different quality of service standards. The discrete-time non-preemptive priority queuing model with priority jumps is proposed in this paper. On the basis of probability generating functions mean system contents and mean queuing delay characteristics are obtained....
