in many signal processing applications, an appropriate measure to comparetwo signals plays a fundamental role in both implementing the algorithm andevaluating its performance. several techniques have been introduced in literature assimilarity measures. however, the existing measures are often either impractical forsome applications or they have unsatisfactory results in some other applications....
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....
in this paper, a state feedback h¥ controller is proposed in order to design an active queue management (aqm) system based on congestion control algorithm for networks supporting tcp protocols. in this approach, the available link bandwidth is modeled as a time-variant disturbance. the purpose of this paper is to design a controller which is capable of achieving the queue size and can guarantee...
In this paper we consider a two-level inventory system with one warehouse and one retailer with information exchange. Transportation times are constant and retailer faces independent Poisson demand. The retailer applies continuous review (R,Q)-policy. The supplier starts with m initial batches (of size Q), and places an order to an outside source immediately after the retailer’s inventory posit...
The random time delay in a networked control system can usually deteriorate the control performance and stability of the networked control system. In order to solve this problem, this paper puts forward a networked control system random time-delay compensation method based on time-delay prediction and improved implicit generalized predictive control (GPC). The least squares support vector machi...
this paper deals with a delayed ratio-dependent functional response predator-prey model with a threshold harvesting policy. we study the equilibria of the system before and after the threshold. we show that the threshold harvesting can improve the undesirable behavior such as nonexistence of interior equilibria. the global analysis of the model as well as boundedness and permanence properties a...
Background: Operating room (OR) is one of the main hospital parts and management of time and cost are very important in this essential unit. Also, due to the close relationship with other departments, improving its service quality and performance, significantly increases the efficiency of hospital. OR is a complex system in which each lack of coordination effects on all hospita...
