Aging rate (AR) of dielectric permittivity (ε33T/ε0) ternary Pb(In1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–xPbTiO3 (PIN–PMN–xPT, x = 26 and 30 mol %) binary Pb(Mg1/3Nb2/3)O3–xPbTiO3 (PMN–xPT, single crystals (SCs) grown by the continuous-feeding Bridgman method (CF-BM) were investigated. The AR was 0.6–2.0 %/decade, whereas that loss SCs 1–8 %/decade. Even though SC growth methods different, CF-BM PMN–30PT...

Increasing power dissipation has become a major constraint for future performance gains in the design of microprocessors. In this paper, we present the circuit design of an issue queue for a superscalar processor that leverages transmission gate insertion to provide dynamic low-cost configurability of size and speed. A novel circuit structure dynamically gathers statistics of issue queue activi...

Active queue management operates at network nodes to control the number of packets in the queue of nodes, by actively receiving packets when the queue is not full, removing packets when the queue is full or notifying bottlenecks even in the embryonic period of the bottlenecks due to to-be-full queue. In recent years, scientists have used fuzzy logic to improve queue management mechanisms. Overa...

A mixed s-stack q-queue layout of a graph consists linear order its vertices and partition edges into s stacks q queues, such that no two in the same stack cross queue nest. In 1992, Heath Rosenberg conjectured every planar admits 1-stack 1-queue layout. Recently, Pupyrev disproved this by demonstrating partial 3-tree does not admit note, we strengthen Pupyrev's result showing conjecture hold e...

In this paper, we consider a discrete-time finite-capacity queue with Bernoulli arrivals and batch services. In this queue, the single server has a variable service capacity and serves the customers only when the number of customers in system is at least a certain threshold value. For this queue, we first obtain the queue-length distribution just after a service completion, using the embedded M...

We study queue abandonment from a hospital emergency department. We show that abandonment is influenced by the queue length and the observable queue flows during the waiting exposure, even after controlling for wait time. For example, observing an additional person in the queue or an additional arrival to the queue leads to an increase in abandonment probability equivalent to a 25-minute or 5-m...

This paper deals with bi-level control policy and queuing analysis of a machine repair problem. The model is developed by incorporating mixed standbys (cold and warm), reneging, set up and vacation time. The repair facility consists of two heterogeneous repairmen in the system. The life and repair time of the failed units and also their set up times are assumed to be exponentially distributed. ...

1 2 The capacity drop indicates that the queue discharge rate is lower than the free-flow 3 capacity. Studies show that queue discharge rates vary under different traffic conditions. 4 Empirical data show that the queue discharge rate increases as the speed in congestion 5 increases. Insights into the underlying behavioral mechanisms that result in such variable 6 queue discharge rates can help...

In this paper, we analyze a scheduling algorithm which is suitable for the heterogeneous traffic network. In the large deviation setting, we are interested to see, how the asymptotic decay rate of maximum queue overflow probability achieved by this algorithm.We first derive an upper bound on the decay rate of the queue overflow probability as the queue overflow threshold approaches infinity. Th...
