In this paper, we discuss the Stochastic Resonance (SR) effect for the binary-input ternary-output (2,3) Discrete Memoryless Channels (DMC). The (2,3) DMC is of great interest for various digital communications channels, including acoustic underwater communication. We focus on the capacity maximization, brought about by additive Gaussian noise, for the (2,3) DMCs. We analyze the capacity of the...

In this paper, we present a joint power scheduling and rate control scheme for wireless ad-hoc networks. Compared with wireline networks, a unique characteristic of wireless networks is that the channel condition is timevarying. By appropriately exploiting the variation of the channel condition at each link, one can more efficiently utilize wireless resources resulting in higher system capacity...

We present a stochastic model for capacity-expansion planning of electricity distribution networks subject to uncertain demand (CEP). We formulate CEP as a multistage stochastic mixed-integer program with a scenario-tree representation of uncertainty. At each node of the scenario-tree, the model determines capacity-expansions, operating con guration, and power ows. A “super-arc” representation ...

An upper boundary point for a demand vector is defined to be a system state vector for which the system capacity is equal to the demand vector, and an increase in its unsaturated components leads to at least one unit of increase in system capacity. System capacity of a singlecommodity stochastic-flow network is the maximum flow from the source node to the sink node of the network. Extending the...

 Numerous problems in engineering and science can be converted into optimization problems. Artificial bee colony (ABC) algorithm is a newly developed stochastic optimization algorithm and has been widely used in many areas. However, due to the stochastic characteristics of its solution search equation, the traditional ABC algorithm often suffers from poor exploitation. Aiming at this weakness o...

In this paper, a stochastic programming approach is applied to the airline network revenue management problem. The airline network with the arc capacitated single hub location problem based on complete–star p-hub network is considered. We try to maximize the profit of the transportation company by choosing the best hub locations and network topology, applying revenue management techniques to al...

Naturally occurred soil deposits inherit heterogeneity and anisotropy in their strength properties. The main purpose of this paper is to model the soil stratum with anisotropy consideration and spatially varying undrained shear strength by using random field theory coupled with finite difference numerical analysis to evaluate their effect on the bearing capacity of the shallow foundations. In t...

In wireless networks, the system capacity can vary unpredictably with time, due to mobility of users and dynamic channel assignment protocols. This variation in capacity with time, known as ‘stochastic capacity’, can have a major impact on the performance measures such as call blocking probability and queueing delay, of the wireless networks. The dependence of the stochastic capacity on the int...
