End-to-end reordering of packets on Internet is investigated. Packet streams transferred over the Internet are used to analyze the long-term and short-term trends in reordering. Reorder Density (RD) is used to capture comprehensively and concisely the nature of reordering present in a stream. Simpler metrics are derived from RD for monitoring of long-term(More)
Knapsack problems are important NP-Complete combinato-rial optimization problems. Although nearly all the classical instances can be solved in pseudo-polynomial time nowadays, yet there are a variety of test problems which are hard to solve for the existing algorithms. In this paper we propose a new approach based upon binary particle swarm optimization(More)
Heterogeneous parallel and distributed computing systems may operate in an environment where certain system performance features degrade due to unpredictable circumstances. Robustness can be defined as the degree to which a system can function correctly in the presence of parameter values different from those assumed. This work develops a model for(More)
Many engineering optimization problems frequently encounter continuous variables and discrete variables which adds considerably to the solution complexity. Very few of the existing methods can yield a globally optimal solution when the objective functions are non-convex and non-differentiable. This paper presents a hybrid swarm intelligence approach (HSIA)(More)

The Shenzhen ETS is the first urban-level " cap-and-trade " carbon emission trading scheme operated in China. This paper focuses on the construction of Shenzhen carbon emission trading scheme. It is devised as the intensity-based cap, output-based allocation and allowance trade carbon market. It has some signatures in the general principles, coverage and(More)

AIM To assess the cytotoxic effect of crotoxin (CrTX), a potent neurotoxin extracted from the venom of the pit viper Crotalus durissus terrificus, in human lung adenocarcinoma A549 cells and investigated the underlying mechanisms. METHODS A549 cells were treated with gradient concentrations of CrTX, and the cell cycle and apoptosis were analyzed using a(More)
