Geocast mechanisms allow a sender to transmit network packets to receivers residing at a certain geographical region. Geocast forms the basis for a number of location-based services, such as announcement services, advertisement services or friend-finders. In this paper, we introduce the notion of semantic geocast, where a target area is specified by its meaning. A sender can broadcast messages ...

An improved study to the s wave πK elastic scatterings and the kappa resonance Abstract We point out that the dispersion relation for the left hand cut integral presented in one of our previous paper (Nucl. Phys. A733(2004)235) is actually free of subtraction constant, even for unequal mass elastic scatterings. A new fit to the LASS data is performed and we find a κ pole with M κ = 694 ± 53M eV...

The present paper is a first attempt to develop a theoretical model using a short-term vis-à-vis long-term contract framework within which donor countries’ endorsement or rejection decision towards the recently proposed International Finance Facility (IFF) is rationalized. The current foreign aid system is portrayed as being similar to a series of short-term contracts, where donor countries are...

Quantum game theory, whatever opinions may be held due to its abstract physical formalism, have already found various applications even outside the orthodox physics domain. In this paper we introduce the concept of a quantum auction, its advantages and drawbacks. Then we describe the models that have already been put forward. A general model involves Wigner formalism and infinite dimensional Hi...

The purpose of this research was to examine the effects of combat identification systems on a soldier’s engagement decision. The research investigated changes in target identification performance and response biases across different simulated battlefield and aid conditions. These conditions were manipulated by changing the costs of making an error and the availability of an aid. Signal detectio...

Complex responses observed in an experimental, nonlinear, moored structural system subjected to nearly periodic wave excitations are examined and compared with the simulations of a newly proposed independent-flow-field (IFF) model in this paper. Variations in wave heights are approximated by additive random perturbations to the dominant periodic component. Simulations show good agreement with t...

Projection is widely used as a diagnostic for presupposition, but many expression types yield projection even though they do not have standard properties of presupposition, for example appositives, expressives, and honorifics (Potts 2005). While it is possible to analyze projection piecemeal, clearly a unitary explanation is to be preferred. Yet we show that standard explanations of projective ...

This paper applies Shannon theory, which was established to describe a discrete general communications system, to a general identification system that is affected by noise (and jamming), the probability of a discrete event occurring (such as an object in a certain region of space), and most importantly, the entropy and dissonance of the information source. This paper analyzes the cause of the m...

Jones and Rachlin (2008) found that the amount of money a person is willing to forgo in order to give $75 to another person decreased as a hyperbolic function of perceived social distance, in the same way as occurs in intertemporal choice. This study aimed to extend this finding to the domain of social networks, in which social distance is defined by degrees of separation. A total of 334 partic...
