Tight cooperative control of mobile entities and resources is essential to enhance the efficiency and effectiveness of terminal operation. The paper aims at developing an integrated simulation model which integrates the traffic flow control of internal tractors and the berth operation of a container terminal for evaluation of control policies adopted. Terminal operation is modeled as a discrete...

We report room-temperature operation of what we believe is the first continuous-wave laser that relies exclusively on cooperative upconversion by coupled ion pairs to achieve population inversion.

In this paper, we focus on cooperative spectrum sensing (CSS) for double threshold improved energy detector. In this method, the improved energy detector compares positive power operation p of the amplitude of received signals at each secondary user (SU) with two thresholds to make binary decision about presence or absence of primary user (PU). The energies lying between upper and lower thresho...

The functions of most genetic circuits require a sufficient degree of cooperativity in the circuit components. Although mechanisms of cooperativity have been studied most extensively in the context of transcriptional initiation control, cooperativity from other processes involved in the operation of the circuits can also play important roles. In this work, we examine a simple kinetic source of ...

Material balance equations describe the dynamics of the species in open reaction systems and contain information regarding reaction topology, kinetics and operation mode. For reaction systems, the state variables (the numbers of moles, or concentrations) have recently been transformed into decoupled reaction variants (extents of reaction), and reaction invariants (extents of flow) (Amrhein et a...

Wireless sensor networks (WSNs) have gained tremendous attention in recent years due to their numerous applications. Due to the limited energy resource, energy efficient operation of sensor nodes is a key issue in wireless sensor networks. Cooperative caching which ensures sharing of data among various nodes reduces the number of communications over the wireless channels and thus enhances the o...

A feedback-based scheme for energy conservative cooperative content distribution for mobile systems is presented together with analysis of its behavior in simulated operation. The mechanism described is designed to address problems of co-operation in transient groups, where group members are assumed to act selfishly to preserve their limited resources. Properties of the resulting barter-trade l...

It is an ordinary need for cooperative applications to merge different versions of an object to a common state. Though many approaches exist, they are either too complex to implement or not flexible enough to meet the various high-level requirements. To solve the problem, a general merging algorithm is developed based on object marking, i.e., the contents of an object are marked with appropriat...

Cooperative path-finding can be abstracted as computing non-colliding paths for multiple agents between their start and goal locations on a graph. This paper proposes a fast algorithm that can provide completeness guarantees for a general class of problems without any assumptions about the graph’s topology. Specifically, the approach can address any solvable instance where there are at most n-2...
