In this paper a simulation model for visual attention is discussed and formally analysed. The model is part of the design of an agent-based system that supports a naval officer in its task to compile a tactical picture of the situation in the field. A case study is described in which the model is used to simulate a human subject’s attention. The formal analysis is based on temporal relational s...

The growing part of the New Technologies of Information and Communication (NTIC) comes along with the passage on numeric support of many documentary capitals. So, we attend gradually the digitalization of working documents of all kinds: medical files, educational files, technical documentations, etc. But how make sure that this change of paradigm benefits the readers and the authors of document...

Plant lateral roots have a defined developmental pattern and shape, but a key question is whether strict regulation underlies observed regularity. A new study uses long-term in toto live imaging and simulations to show that organogenesis rather follows self-organizing principles.

The energy-momentum conservation law is used to investigate the interaction of pulses in the framework of nonlinear electrodynamics with Lorentz-invariant constitutive relations. It is shown that for the pulses of the arbitrary shape the interaction results in phase shift only.

This study examines the behavior of simple n-person bargaining problems under pre-donations where the Kalai-Smorodinsky (KS) solution is operant. Pre-donations are a unilateral commitment to transfer a portion of one’s utility to someone else, and are used to distort the bargaining set and thereby influence the bargaining solution. In equilibrium, these pre-donations are Pareto-improving over t...

In this research, we develop a conceptual model to explain the relationship between knowledge infrastructure, knowledge sharing (KS) and innovation capability, using system dynamics approach. This research is important since it will provide better understanding on what infrastructures are critical to support KS activities, and how KS will affect the capability of enterprise to innovate, and how...

Knowledge Management (KM) is critical in ensuring process efficiency, outcome effectiveness and improved organizational memory for the modern day business enterprises. Knowledge Sharing (KS) is fast becoming a rapidly growing area of interest in the domain of knowledge management. The purpose of this paper is to enlist a set of generalized metrics that can be used to evaluate the efficiency and...

According to previous studies, expert performers construct their acoustical (i.e. durational, dynamical) and visual (i.e. motional) expressions by highlighting the structurally important points. However, it is still unclear whether such expressions are influenced by the presence of the audience. In the present study, we examined the effects of context (i.e. audience present versus audience abse...

A proposal concerning the status of the semantic relation between the consequent clause of a conditional sentence and the conditional sentence itself is made: this relation corresponds to the dual of presupposition, in the technical sense. It holds not only for conditional declaratives but also for conditional questions, imperatives and exclamatives. Technically this is possible because conditi...

We report on our analysis of a 274 ks observation of the Vela pulsar with the Rossi X-Ray Timing Explorer (RXTE). The double-peaked, pulsed emission at 2 30 keV, which we had previously detected during a 93 ks observation, is confirmed with much improved statistics. There is now clear evidence, both in the spectrum and the light curve, that the emission in the RXTE band is a blend of two separa...
