A statistical analysis of functional data, obtained as reflectance values measured using a hyperspectral sensor, was used to determine water content in vine leaves. Our study was conducted using a sample of 80 vine leaves whose water content was determined by calculating the weight difference between leaves before and after drying in an oven. Two regression models, one linear and the other non-...

This paper studies scenarios of cyclic dominance in a coevolutionary spatial model in which game strategies and links between agents adaptively evolve over time. The Optional Prisoner’s Dilemma (OPD) game is employed. The OPD is an extended version of the traditional Prisoner’s Dilemma where players have a third option to abstain from playing the game. We adopt an agent-based simulation approac...

This paper studies equilibrium selection based on a class of perfect foresight dynamics and relates it to the notion of p-dominance. A continuum of rational players are repeatedly and randomly matched to play a symmetric n × n game. There are frictions: opportunities to revise actions follow independent Poisson processes. The dynamics has stationary states, each of which corresponds to a Nash e...

Orthogonal variable spreading factor (OVSF) codes provide variable data rate transmissions for different bandwidth requirements in 3G WCDMA networks. In order to effectively utilize limited OVSF resources, many works in the literature have focused on dynamic code assignment (DCA) schemes. This paper investigates genetic algorithm (GA) based approach for dynamic OVSF code assignment in WCDMA net...

In cooperatively-breeding species, the sexes of subordinate group members may have important consequences for dominant individuals. We varied subordinates’ sexes in aquariumhoused groups of the cooperatively-breeding cichlid fish Neolamprologus pulcher, and compared the behaviours of dominant individuals in groups with sameversus oppositesex subordinates. Dominants tended to be more aggressive ...

The Financial Modernization Act (FMA) of 1999 permits banks, securities ®rms, and insurance companies to combine and compete with each other in all types of ®nancial services. No longer are the names of ®nancial institutions synonymous with their particular products. This suggests moving from an``institutional perspective'' that focuses upon the historical specializations of institutions, to a ...

In optimal planning as heuristic search, admissible pruning techniques are paramount. One idea is dominance pruning, identifying states “better than” other states. Prior approaches are limited to simple dominance notions, like “more STRIPS facts true” or “higher resource supply”. We apply simulation, well-known in model checking, to compute much more general dominance relations based on compari...

The standard RSA cryptosystem is not semantically secure. Pointcheviel proposed a variant of RSA cryptosystem with the property of semantic security by introducing a new problem known as DRSA problem. He called it DRSA scheme. In this paper, we underlined a shortcoming of that scheme and proposed an alternative DRSA public key cryptosystem.

One of the primary differences between humans and other animals is our capacity for high level cognition and the use of language. Historically, AI has understandably focused on duplicating these aspects of human behavior, and selected its architectures accordingly. However, humans are nevertheless social mammals and share a large part of the mammalian behavior repertoire, such as feeding, as we...
