The correct and e cient management of data in distributed databases or mobile computing environments is di cult. Communication disruptions within such systems render the execution of database transactions problematic due to di culties in atomic commitment strategies. A previously proposed non-traditional system for data and operators, with single site transaction executions and decentralized co...

This paper presents a generic architecture for an agent capable of designing and creating new agents. The design agent is based on an existing generic agent model, and includes a model for design, in which strategic reasoning and dynamic management of requirements are explicitly modelled. The model includes an explicit formal representation of (1) requirements that can be formulated for agents ...

In collaborative learning contexts, the problem of automatically forming effective learning groups gets considerably complex with larger class sizes, e.g. in MOOCs. Additionally, group dynamics caused by high dropout rates currently observable on online open course platforms poses challenges to learning group formation strategies. To address these problems, this paper presents PSO-based algorit...

This paper describes the use of Belief Networks (BNs) for dynamic semantic modeling within the United Airlines’ FLight InFOrmation service (FLIFO). Callers can speak naturally to obtain status information about all flights (including arrival and departure times) of United Airlines. In this work we aim at enabling the application to utilize dynamic call information to improve speech recognition ...

The problem of comparing two sequences S and T to determine their similarity is one of the fundamental problems in pattern matching. In this manuscript we will be primarily concerned with sequences as our objects and with various string comparison metrics. Our goal is to survey a methodology for utilizing repetitions in sequences in order to speed up the comparison process. Within this framewor...

Dynamic binary translation is the process of translating, modifying and rewriting executable (binary) code from one machine 4 to another at run-time. This process of low-level re-engineering consists of a reverse engineering phase followed by a forward 5 engineering phase. 6 UQDBT, the University of Queensland Dynamic Binary Translator, is a machine-adaptable translator. Adaptability is provide...

We consider the ‘classical’ single product dynamic pricing problem allowing the ‘scale’ of demand intensity to be modulated by an an exogenous ‘market size’ stochastic process. This is a natural model of dynamically changing market conditions. We show that for a broad family of Gaussian market size processes, simple dynamic pricing rules that are essentially agnostic to the specification of thi...

In the present study we attempt to induce a quadruped robot to walk dynamically on irregular terrain and run on at terrain by using a nervous system model. For dynamic walking on irregular terrain, we employ a control system involving a neural oscillator network, a stretch re ex and a exor re ex. Stable dynamic walking when obstructions to swinging legs are present is made possible by the exor ...

We design an experiment to compare investors’ final wealth distribution in a static setup and an equivalent dynamic setup. In the static setup investors can trade all risks since there are as many securities as states of the world. In the dynamic market there are too few securities for investors to achieve efficient final wealth holdings without re-trade. Information disclosure and the possibil...

The classic dynamic programming approach is not applicable to the airline network revenue management (RM) problem of a practical size due to the curse of dimensionality. Many heuristic methods, including the most popular bid-price control approach, generate the approximate control decisions based on various static formulations, which need to be re-solved to take into account the dynamic feature...
