A virtual testbed for analysis and design of sensorimotoric aspects of agent control
1997
Abstract In this paper XRaptor is introduced, an object-oriented simulation tool. It provides a virtual multi-agent world which acts as testbed for agent control mechanisms. This environment encompasses a 3-dimensional space, in which the agents may move. Currently agents are realized modelling some abstract properties of flies and bats. XRaptor provides different levels of information flow and world manipulation capabilities from the agents' point of view. A further purpose of XRaptor is educational: Different teams of developers may design control units for agents which can then be subjected to a tournament.
A Reference Scenario for IMS Strategic Design
1999
Today is fully acknowledged that manufacturing is a formidable competitive weapon. The strength of such a weapon is essentially defined during the first step of the design phase called strategic design. During this phase, in fact, the principal characteristics of the manufacturing systems are to be defined taking into account the competitive environment and the competition strategy. Classical analytical models for IMS design often neglect this aspect and, perhaps, this is one of the causes of IMS failure. The paper proposes a set of analytical models for strategic IMS design; they have been classified into four classes, each one pursuing a determined set of objectives, providing, in this wa…
Local Monitor Implementation for Decentralized Intrusion Detection in Secure Multi–Agent Systems
2007
This paper focuses on the detection of misbehav- ing agents within a group of mobile robots. A novel approach to automatically synthesize a decentralized Intrusion Detection System (IDS) as well as an efficient implementation of local monitors are presented. In our scenario, agents perform possi- bly different independent tasks, but cooperate to guarantee the entire system’s safety. Indeed, agents plan their next actions by following a set of logic rules which is shared among them. Such rules are decentralized, i.e. they depend only on configurations of neighboring agents. However, some agents may not be acting according to this cooperation protocol, due to spontaneous failure or tampering.…
Magister : revista de formación del profesorado e investigación educativa
2016
La competencia colaborativa es una herramienta muy útil para el alumnado universitario. La diversidad de ámbitos profesionales que existen hoy en día demanda unos trabajadores competentes que se adapten a una realidad laboral compleja y cambiante. En este sentido, las relaciones interpersonales cobran gran importancia al requerir la colaboración entre profesionales para conseguir un objetivo final. El presente artículo describe una propuesta de trabajo colaborativo que se llevó a cabo con el alumnado universitario del cuarto curso de Magisterio de la Universitat de València que cursaban el itinerario de especialización en Educación Musical. Collaborative competition is a very useful tool fo…
Beyond MAYA for game-changing multisensory design
2017
With information technology becoming ever more embedded in our surrounding everyday things, the nature of interactions and the way we experience digitalization is becoming increasingly embodied. Thus, growing effort is placed on examining the multisensory nature of interaction experience. From a design perspective, increased knowledge of how people experience materials and how to design to encourage varying material experiences opens new opportunities for the generation of rich multisensory user experience, and accomplishing game-changing results. In particular, the innovation space opened up by understanding people's material expectations of designs is significant. An experiment (N = 78) w…
The Use of Cluster Analysis to Segment Clients of a Sport Center in Spain
2005
Abstract This research examines the motivation profiles of 218 consumers at a sport center in Valencia, Spain. We employed the Motivation in Sport Scale (MISS–Sport Center) with the following eight motives (factors): Positive Affect, Social Contact, Physical Exercise, Coping Strategy, Challenge, Body Image, Competition, and Entertainment. There were significant differences in consumers’ motives across gender, age, and marital status. We identified five motivation profiles using the eight motives of MISS–Sport Center: Non-Competitive Leisure-Oriented Exercisers, Practical Social Entertainers, Affective Users, Enthusiastic Sportspersons, and Passive Participants. There were differences in dem…
Establishment and interspecific associations in two species of Ichthyocotylurus (Trematoda) parasites in perch (Perca fluviatilis)
2011
Abstract Background Co-infections of multiple parasite species in hosts may lead to interspecific associations and subsequently shape the structure of a parasite community. However, few studies have focused on these associations in highly abundant parasite species or, in particular, investigated how the associations develop with time in hosts exposed to co-infecting parasite species for the first time. We investigated metacercarial establishment and interspecific associations in the trematodes Ichthyocotylurus variegatus and I. pileatus co-infecting three age cohorts of young perch (Perca fluviatilis). Results We found that the timing of transmission of the two Ichthyocotylurus species was …
Entrepreneurship of an institutional field: the emergence of coworking spaces for digital business model
2020
AbstractCoworking spaces have been proliferating world-wide in urban and rural areas while facilitating entrepreneurship and new, especially digital business models. Our research analyzes the worldwide expansion by drawing upon mechanisms from institutional theory. We argue that the sense of community, emotional activation, the local communities together with the digital linkages and the open office allowed coworking spaces to evolve as a real space for entrepreneurship. The common lifestyle and the high digital identity of the users further explain the emergence of this entrepreneurship field that shows high convergent forms of coworking spaces. The key divergence comes with different owne…
ENDOGENOUS TIMING WITH FREE ENTRY
2006
A free entry model with linear costs is considered where firms first choose their entry time and then compete in the market according to the resulting timing decisions. Multiple equilibria arise allowing for infinitely many industry output configurations encompassing one limit-output dominant firm and the Cournot equilibrium with free entry as extreme cases. Sequential entry is never observed. Both Stackelberg and Cournot-like outcomes are sustainable as equilibria however. When the number of incumbents is given, entry is always prevented, and industry output is sometimes larger than the entry preventing level.
Ecotoxicological studies with the freshwater rotifer Brachionus calyciflorus. Resource competition between rotifers and daphnids under toxic stress
1993
Abstract This study examined the ability of the freshwater rotifer Brachionus calyciflorus to coexist with the large cladoceran Daphnia magna, and the effect of sublethal concentrations of copper on the competition between both species. Preliminary laboratory experiments showed that large Daphnia (> 1.2 mm) can kill and rapidly exclude the rotifer B. calyciflorus in mixed-species cultures. Brachionus populations were suppressed by Daphnia both through exploitative competition for shared, limited food resources and through mechanical interference. At a food concentration of 1 X 105 cells/ml of Nannochloris oculata, competition caused high mortality rates and decreased fertility in the rotife…
