In this paper we present GAMYGDALA, an emotional appraisal engine that enables game developers to easily add emotions their Non-Player Characters (NPC). Our approach proposes a solution is positioned between event coding of affect, where individual events have predetermined annotated consequences for NPCs, and full blown cognitive model. Instead, NPC needs the developer defines goals annotates with relation these goals. Based on input, GAMYGDALA produces emotion according well-known OCC...

We model and evaluate an infrastructure based cognitive radio network where impatient unlicensed or secondary users (SUs) offer elastic traffic. The interference created by SUs to the licensed is analyzed when uses two different spectrum access schemes, conventional random scheme a new we refer as with preference. To further control interference, limit set number of channels have to. With this constraint, abandonment probability, mean delay throughput degrades significantly. improve QoS...

Cognitive radio networks are expected to address and resolve important operational challenges such as opportunistic spectrum access, network heterogeneities requests for the provision of diverse Quality-of-Service (QoS) different applications. Accordingly, a number functionalities required take into account these towards efficient management cognitive networks. This paper advances new architecture The is designed developed at application layer incorporates sensing prediction, addressing...

Recent advances in the fields of Cognitive Radio and proliferation open spectrum access promise that spectrum-agile wireless communication will be widespread near future, bring significant flexibility potential utility improvements for end users. With efficiency being a key objective, most relevant research focuses on smart coexistence mechanisms. However, nodes may behave selfishly should considered as rational autonomous entities. Selfishness, pure malice or even faulty equipment can lead...

The European Space Agency (ESA) is developing an optical inter-orbit communication system enabling a link between low earth orbiting (LEO) and geostationary (GEO) spacecraft. allows the transmission of 50 Mbps LEO GEO in experimental pre-operational mode. uses laser diodes typically 100 mW power at wavelength 830 nanometer. Direct intensity modulation applied. Telescopes 25 cm diameter are used on both terminals. breadboard phase has been completed launch terminals scheduled for 1994. Other...

Abstract Cognitive radio (CR) networks allow secondary users (SUs) to opportunistically access licensed spectrum, thus providing efficient use of resources. Different studies carried out on CR have focused the procedure spectrum handoff SUs such as data transmission in a communication that can be different channels. In this paper, we consider cellular enhanced with facilities for where user call progress moves across neighbouring cells, is, so‐called inter‐cell handoff. Our model assumes...

The paper advances a new architecture for seamless roaming, which is implemented at the application layer. This subject research projects PERIMETER and MOBICOME, recently granted by EU STREP FP7 EUREKA, respectively. challenges are on mobility management, security, QoE overlay routing, node positioning, modeling prediction, middleware handover. foundation of handover provided several components, most important ones being handover, connectivity management Internet mobility. provides an...

Cognitive Radio Networks (CRNs) are expected to address and resolve important technological operational challenges of future networks, such as Dynamic Spectrum Access (DSA), routing in heterogeneous networks provision Quality Experience (QoE) for different applications. Accordingly, a number new terminal network functionalities required solve the technical problems provide efficient management CRNs. The paper advances solution CRNs, providing communication between Secondary Users (SUs)...

The European Space Agency ESA is developing an optical inter-orbit communication system enabling a link between low-Earth orbiting (LEO) and geostationary spacecraft (GEO). This so-called SILEX allows transmission of 50 Mbps from LEO to GEO in experimental pre-operational mode. uses GaAlAs laser diodes operating at 60 mW average power direct detection. Both terminals are phase C/D. will be launched on board the satellite ARTEMIS French SPOT 4 with nominal launch dates 1996 1995,...

Triple-valve replacement in active infective endocarditis has rarely been reported. This paper is the first report of a triple-valve performed with septic shock and presentation multivalvular due to Rhizobium radiobacter.A 26-year-old patient neglected ventricular septal defect referred us shock, multiple organ failure, severe biventricular dysfunction, pulmonary hypertension, radiobacter affecting aortic, tricuspid valves. Initially, he was deemed unfit for surgery. However, after clinical...
