In this comparative study we investigate the performance of AlGaN/GaN based MSM varactor diodes based on HFET and MOSHFET layer systems. Device fabrication uses standard HFET fabrication technology, allowing easy integration in MMICs. Devices with different electrode geometries are characterized by DC and by S-parameter measurements up to 50 GHz. The HFET based varactors show capacitance ratios up to 14. The MOSHFET based devices, on the other hand, exhibit lower capacitance ratios and poorer stability because of theinsulation layer between electrodes and semiconductor. [less ▲]

An increased RF-Performance of heterojunction field-effect transistor was found to be due to passivation and in addition a SiO2 insulation underneath the gate metallization. This leads to an increase of cutoff frequency from 17 GHz up to 24 GHz for devices with 500 nm gate length. The RF output power increased from 4.1 to 6.7 W/mm at 7 GHz. RF simulation based on measured S-parameter showed a decrease of gate-source-capacitance and transconductance for devices with a dielectric layer underneath the gate metallization. The increase of the ratio gm/Cgs of about 25% is in agreement with the measured cutoff frequency ft. [less ▲]

In [Zampunieris, 2006] we proposed a new kind of Learning Management Systems: proactive LMS, designed to help their users to better interact online by providing programmable, automatic and continuous analyses of users (inter-) actions augmented with appropriate actions initiated by the LMS itself. The proactive part of our LMS is based on a dynamic rules-based system. But the main algorithm we proposed in order to implement the rules running system, suffers some efficiency problems. In this paper, we propose a new version of the main rules running algorithm that is based on lazy evaluation in order to avoid unnecessary and time-costly requests to the LMS database when a rule is not activated, that is: when its actions part will not be performed because preliminary checks failed.

Reinforcement learning (RL) was originally proposed as a framework to allow agents to learn in an online fashion as they interact with their environment. Existing RL algorithms come short of achieving this goal because the amount of exploration required is often too costly and/or too time consuming for online learning. As a result, RL is mostly used for offline learning in simulated environments. We propose a new algorithm, called BEETLE, for effective online learning that is computationally efficient while minimizing the amount of exploration. We take a Bayesian model-based approach, framing RL as a partially observable Markov decision process. Our two main contributions are the analytical derivation that the optimal value function is the upper envelope of a set of multivariate polynomials, and an efficient point-based value iteration algorithm that exploits this simple parameterization.

Coordination graphs offer a tractable framework for cooperative multiagent decision making by decomposing the global payoff function into a sum of local terms. Each agent can in principle select an optimal individual action based on a variable elimination algorithm performed on this graph. This results in optimal behavior for the group, but its worst-case time complexity is exponential in the number of agents, and it can be slow in densely connected graphs. Moreover, variable elimination is not appropriate for real-time systems as it requires that the complete algorithm terminates before a solution can be reported. In this paper, we investigate the max-plus algorithm, an instance of the belief propagation algorithm in Bayesian networks, as an approximate alternative to variable elimination. In this method the agents exchange appropriate payoff messages over the coordination graph, and based on these messages compute their individual actions. We provide empirical evidence that this method converges to the optimal solution for tree-structured graphs (as shown by theory), and that it finds near optimal solutions in graphs with cycles, while being much faster than variable elimination.

Decentralized partially observable Markov decision processes (DEC-POMDPs) form a general framework for planning for groups of cooperating agents that inhabit a stochastic and partially observable environment. Unfortunately, computing optimal plans in a DEC-POMDP has been shown to be intractable (NEXP-complete), and approximate algorithms for specific subclasses have been proposed. Many of these algorithms rely on an (approximate) solution of the centralized planning problem (i.e., treating the whole team as a single agent). We take a more decentralized approach, in which each agent only reasons over its own local state and some uncontrollable state features, which are shared by all team members. In contrast to other approaches, we model communication as an integral part of the agent's reasoning, in which the meaning of a message is directly encoded in the policy of the communicating agent. We explore iterative methods for approximately solving such models, and we conclude with some encouraging preliminary experimental results. [less ▲]

Researchers studying climate change have used historical tide gauge measurements from all over the world to investigate the changes in sea level that have occurred over the last century or so. However, such estimates are a combination of any true sea level variations and any changes in ground level at the specific tide gauge. For a tide gauge record to be used to determine the climate related changes in sea level it is necessary to correct for any changes in ground level. The development in geodetic techniques for monitoring changes in ground level at British tide gauges has been on-going at the IESSG and POL since 1990, based on research funded by both Defra and the Environment Agency. Since 1996, this research has focused on the establishment of continuous GPS (CGPS) stations and the use of absolute gravity (AG), as independent geodetic techniques for measuring changes in ground level. This paper details the results of Defra/EA R&D project FD2319, which is part of the Risk Evaluation and Understanding of Uncertainty Theme. The paper shows how CGPS and AG have been used on a national scale to monitor changes in ground level at tide gauges and obtain estimates of changes in sea level, decoupled from changes in ground level.

In life sciences, scientists are confronted with an exponential growth of biological data, especially in the genomics and proteomics area. The efficient management and use of these data, and its transformation into knowledge are basic requirements for biological research.

We will present the status of our efforts for the realization of an automated protein prediction pipeline as an example for a complex biological workflow scenario in a Grid environment based on Web services.

In this paper we report on the use of XML transformations in the context of Enterprise Architectures. We show that XML transformation techniques can be applied to visualize and analyze enterprise architectures in a formal way. We propose transformational techniques to extract views from an XML document containing architectural information and indicate how to perform a specific form of impact analysis on this information. The transformations are formally expressed with the language RML, a compact yet powerful transformation language developed at CWI, which obtains its power from regular expressions defined on XML documents. We discuss a tool that has been built on top of it to visualize the results of the transformations and illustrate the advantages of our approach: the genericity of XML, the application of a single technique (namely XML transformations) for various tasks, and the benefits of having a model viewer which is in complete ignorance of the architectural language used.

This paper is about control mechanisms for virtual organizations. As a case study, we discuss the Renewables Obligation (RO), a control mechanism that was introduced in the United Kingdom to stimulate the production of renewable energy. We apply a conceptual model based on normative multiagent systems (NMAS). We propose to model both the participants and the normative system as autonomous agents, having beliefs and goals. Norms, which can be internalized by the agents as obligations, are translated into conditional beliefs and goals of the normative system, which concern both detection and sanctioning measures. We show that the model can handle both the regulative and the evidential aspects of the case. [less ▲]

Design by contract is a well known theory that views software construction as based on contracts between clients (callers) and suppliers (routines), relying on mutual obligations and benefits made explicit by assertions. However, there is a gap between this theory and software engineering concepts and tools. For example, dealing with contract violations is realized by exception handlers, whereas it has been observed in the area of deontic logic in computer science that violations and exceptions are distinct concepts that should not be confused. To bridge this gap, we propose a software design language based on temporal deontic logic. Moreover, we show how preferences over the possible outcomes of a supplier can be added. We also discuss the relation between the normative stance toward systems implicit in the design by contract approach and the intentional or BDI stance popular in agent theory. [less ▲]

In this paper we reconsider the definition of counts-as relations in normative multiagent systems: counts-as relations do not always provide directly an abstract interpretation of brute facts in terms of institutional facts. We argue that in many cases the inference of institutional facts from brute facts is the result of actions of agents acting on behalf of the normative systems and who are in charge of recognizing which institutional facts follow from brute facts. We call this relation delegation of power: it is composed of a counts-as relation specifying that the effect of an action of an agent is an institutional fact and by a goal of the normative system that the fact is considered as an institutional fact. This relation is more complex than institutional empowerment, where an action of an agent counts-as an action of the normative system but no goal is involved, and than delegation of goals, where a goal is delegated to an agent without giving it any power. With two case studies we show the importance of the delegation of power. Finally, we show how the new definition can be related with existing ones by using different levels of abstraction. [less ▲]

Logical architectures combine several logics into a more complex logical system. In this paper we study a logical architecture using input/output operations corresponding to the functionality of logical components. We illustrate how the architectural approach can be used to develop a logic of a normative system based on logics of counts-as conditionals, institutional constraints, obligations and permissions. In this example we adapt for counts-as conditionals and institutional constraints a proposal of Jones and Sergot, and for obligations and permissions we adapt the input/output logic framework of Makinson and van der Torre. We use our architecture to study logical relations among counts-as conditionals, institutional constraints, obligations and permissions. We show that in our logical architecture the combined system of counts-as conditionals and institutional constraints reduces to the logic of institutional constraints, which again reduces to an expression in the underlying base logic. Counts-as conditionals and institutional constraints are defined as a pre-processing step for the regulative norms. Permissions are defined as exceptions to obligations and their interaction is characterized. [less ▲]

Social roles structure social institutions like organizations in Multi-Agent Systems (MAS). In this paper we describe how to introduce the notion of social role in programming languages. To avoid the commitment to a particular agent model, architecture or language, we decided to extend Java, the most prominent object oriented programming language, by adding social roles. The obtained language allows an easier implementation of MAS’s w.r.t. the Java language. We also show that many important properties of social roles, studied in the MAS field, can be applied to objects. Two are the essential features of social roles according to an analysis reported in the paper: social roles are defined by other entities (called institutions), and when an agent plays a role it is endowed with powers by the institution that defines it. We interpret these two features into the object oriented paradigm as the fact that social roles are objects, which are defined in and exist only inside other objects (corresponding to institutions), and that, through a role, external objects playing the role can access to the object (institution) the role belongs to.

In order to create adaptive Agent Systems with abilities matching those of their biological counterparts, a natural approach is to incorporate classical conditioning mechanisms into such systems. However, existing models for classical conditioning are usually based on differential equations. Since the design of Agent Systems is traditionally based on qualitative conceptual languages, these differential equations are often not directly appropriate to serve as an input for Agent System design. To deal with this problem, this paper explores a formal description and analysis of a conditioning process based on logical specification and analysis methods of dynamic properties of conditioning. Specific types of dynamic properties are global properties, describing properties of the process as a whole, or local properties, describing properties of basic steps in a conditioning process. If the latter type of properties are specified in an executable format, they provide a temporal declarative specification of a simulation model. Global properties can be checked automatically for simulated or other traces. Using these methods the properties of conditioning processes informally expressed by Los and Heuvel [8] have been formalised and verified against a specification of local properties based on Machado [9]’s mathematical model [less ▲]

We identify which axioms model social concepts like organization and role and which properties distinguish them from other categories like objects and agents: the organizational structure of institutions, the relation between roles and organizations, and the powers among the components of an organization. All social concepts depend on descriptions defining them, which are collectively accepted, and the description defining the components of organizations, including roles, are included in the description of the organizations they belong to. Thus, the relational dependence of roles means that they are defined in the organizations they belong to. Finally, powers inside organizations are defined by the fact that components of an orga- nization can access the state of the organization whose definition they depend on and of the other components, thus violating the standard encapsulation principle of objects [less ▲]

In this paper, we consider the design of normative multiagent systems composed of both constitutive and regulative norms. We analyze the properties of constitutive norms, in particular their lack of reflexivity, and the trade-off between constitutive and regulative norms in the design of normative systems. As methodology we use the metaphor of describing social entities as agents and of attributing them mental attitudes. In this agent metaphor, regulative norms expressing obligations and permissions are modelled as goals of social entities, and constitutive norms expressing “counts-as” relations are their beliefs.

In this paper we present a new vision of objects in ontologies where the objects’ attributes and operations depend on who is interacting with them. This vision is based on a new definition of the notion of role, which is inspired by the concept of affordance as developed in cognitive science. The current vision of objects considers attributes and operations as being objective and independent from the interaction. In contrast, in our model interaction with an object always passes through a role played by another object manipulating it. The advantage is that roles allow to define operations whose behavior changes depending on the role and the requirements it imposes, and to define session aware interaction, where the role maintains the state of the interaction with an object. Finally, we provide a description of the model in UML and we discuss how roles as affor- dances have been introduced in Java [less ▲]

Landscape maps are a technique for visualizing enterprise architectures. They present architectural elements in the form of an easy to understand 2D ’map’. A landscape map view on architectures provides non-technical stakeholders, such as managers, with a high-level overview, without burdening them with technicalities of architectural drawings. In this paper we discuss the use of and techniques for landscape maps. A formal model for landscape maps is introduced as the basis of visualization and interaction techniques. Moreover, we show how a landscape map can be generated from its underlying model. Finally we show several interaction techniques, for example to build a landscape map from scratch, independently of an underlying model, or to change a landscape map together with its underlying model [less ▲]

Recently, many researchers are working on semantics preserving model transformation. In the field of graph transformation one can think of translating graph grammars written in one approach to a behaviourally equivalent graph grammar in another approach. In this paper we translate graph grammars developed with the GROOVE tool to AGG graph grammars by first investigating the set of core graph transformation concepts supported by both tools. Then, we define what it means for two graph grammars to be behaviourally equivalent, and for the regar/ded approaches we actually show how to handle different definitions of both - application conditions and graph structures. The translation itself is explained by means of intuitive examples. [less ▲]

Sesqui-pushout (sqpo) rewriting – ''sesqui´´ means ``one and a half'' in Latin – is a new algebraic approach to abstract rewriting in any category. sqpo rewriting is a deterministic and conservative extension of double-pushout (dpo) rewriting, which allows to model ``deletion in unknown context'', a typical feature of single-pushout (spo) rewriting, as well as cloning. After illustrating the expressiveness of the proposed approach through a case study modelling an access control system, we discuss sufficient conditions for the existence of final pullback complements and we analyze the relationship between sqpo and the classical dpo and spo approaches.

The application of mathematical programming methodologies to biochemical systems is demonstrated with the presentation of a linear programming (LP) algorithm for calculating minimal pathway distances in biochemical networks. Minimal pathway distances are identified as the smallest number of steps separating two nodes in the network. Two case studies are examined: 1) the minimal distances for Escherichia coli Small Molecule Metabolism (SMM) enzymes are calculated and their correlations with genome distance and enzyme function are considered; 2) a study of the p53 cell cycle and apoptosis control network is performed in order to assess the survivability of the network to both random node failures and a directed assault, by studying the modification of the network’s diameter for successive protein knockouts. The results verify the applicability of the algorithm to problems of biochemical nature. [less ▲]

‘Exigence de qualité’ et ‘vin’ sont devenus presque des synonymes pour quiconque veut acheter une bouteille. Peu d’autres composants que le vin ne sont convoqués pour juger de la qualité d’ensemble d’un repas, indiquant un statut similaire du commentaire sur la ‘qualité individuelle’ du vin servi et sur le ‘talent d’ensemble’ de la personne qui a conçu et préparé le repas. Mais qui dit ‘juger’, dit ‘communiquer’, ‘donner un avis’ tant soit peu argumenté – chose délicate, étant donné que les discours sur le vin se sont peu à peu complexifiés et multipliés . D’où le succès public des cours du soir en œnologie, censés enseigner le discernement sur la qualité, si utile lors de la consommation du vin. Mais peut-on parler d’apprentissage de la qualité ? La consommation de vin peut être schématisée en trois étapes actives – en omettant ici l’étape passive de l’encavement domestique : l’achat après une sélection, le service (en général combiné à un repas), et le fait de boire le vin. Quand la filière professionnelle parle de la nécessité d’ « éducation du consommateur », elle fait référence surtout à un aiguisement sensoriel, permettant d’affiner la perception au nez et en bouche de ce produit très nuancé, dans le double but de faire valoir la qualité intrinsèque de vins élaborés dans cet esprit et, en conséquence, d’infléchir les comportements de consommation, plus conscients car formés et informés, dans cette direction . Or, dans la verbalisation de personnes fréquentant des cours du soir en œnologie, c’est précisément cette troisième étape de la consommation qui est majoritairement présentée comme non problématisée. Ce n’est pas la perception sensorielle de la qualité qui soulève des questions aux yeux des buveurs, mais la sélection lors de l’achat, ainsi que le service de vins de qualité, combinés de manière avantageuse à un plat – c’est-à-dire de sorte que la qualité initiale du vin soit manifeste à tous les convives. De plus, le service devient seulement « difficile » quand il a lieu dans une situation publique : avec des invités ou au restaurant – alors que le choix du vin à apprécier en famille se fait « juste comme ça », de lui-même, sans élaboration de discours. Paraît ainsi une distinction opératoire entre ‘qualité en sphère privée’ et ‘qualité en sphère publique’, plus normée et du coup plus subtile à mettre en œuvre. En conformité avec les attentes générales de la filière professionnelle, les œnologues chargé(e)s des cours du soir en œnologie, se positionnant « dans le sens du terroir », entendent – chacun dans son style d’enseignement individuel – à la fois construire et consolider des compétences cognitives et développer des savoir-faire sensoriels. Afin d’atteindre l’objectif consensuel d’une plus grande autonomie « du consommateur », capable de juger et de départir sans aide extérieure, ce sont les capacités de perception et d’évaluation sensorielle de la qualité qui constituent l’outil ultime. Tandis que les connaissances sur le contexte et le mode de production du vin, constituent un savoir en toile de fond, utile seulement dans ses combinaisons pratiques avec des expériences gustatives directes. Mais les personnes fréquentant ces cours sont surtout attentives à l’exposé oral fait par l’œnologue et voient la dégustation (composée de vins aux propriétés sensorielles ‘didactiques’ et ‘démonstratives’, car toujours « typiques » de leur origine) comme un simple agrément. Les questions qui reviennent le plus souvent sont celles de ‘recettes’ toutes faites sur l’achat et le service des vins, dans un désir de transposabilité à l’identique. Les œnologues résistent à ces pressions en prônant l’entraînement sensoriel (« l’on ne peut que recommander aux gens de goûter »), aboutissant à des opinions individuelles – ce dans un cadre qualitatif maîtrisé, tel qu’il a été présenté dans le cours : « après le cours, les gens ont une possibilité de trouver si un vin est bon ou pas bon ». Au terme de cette interaction entre ‘consommateur apprenant’, désireux de se retrouver dans la jungle des vins espérés de qualité, et les chargé(e)s de cours, on pourrait parler de « malentendu culturel » (Pedler, 2004 : 127) diffus. Comme dans d’autres domaines culturels, effectivement « rien n’indique qu’il existe une adéquation entre offres et réceptions cultivées » (idem : 130). Entre le fait d’entendre ‘dire la qualité’ (par l’œnologue) et l’apprendre dans un cours (pour soi), les médiations semblent incertaines, et les inhibitions ne se lèvent qu’à des conditions individuelles particulières. Notamment la famille et la curiosité affranchie sont des incitateurs puissants pour dépasser la renonciation majoritaire d’aller au bout du voyage entamé. Ces facteurs permettent d’aboutir du « j’aime » ou « je n’aime pas » vers un plaisir de découverte, d’expérimentation et d’énonciation du ‘pourquoi’ de la qualité. [less ▲]

Complex fault-tolerant distributed systems have a growing need of new functional and quality requirements. An immediate consequence of this is an increasing need of new methods for developing complex fault-tolerant distributed applications. Coordinated Atomic Actions (CAAs), making use of exception handling mechanism, offer an approach to ensure the needed requirements of reliability, availability and fault tolerance. Unfortunately, there is currently no method for the high-level modeling of such systems. In this paper, in order to offer an instrument for modeling exception handling, we propose a UML2.0 Platform Independent Profile for CAAs that allows designers to describe complex systems separating the specification from the implementation on a specific technology platform.

More than two years of data of the champ satellite mission is available and the usage of the energy balance approach for global gravity field recovery has been successfully implemented by several groups around the world. This paper addresses two important aspects of the data processing. First, high-quality gravity recovery requires numerical differentiation of kinematic positions. Two methods are investigated using simulated and real dynamic data. It is shown that a third order Taylor differentiator is sufficient to reach good results. Second drift due to the accelerometer bias has to be corrected. Two possible approaches are discussed: cross-over calibration on the one hand calibration w.r.t. a reference model on the other hand. Currently the crossover calibration fails due to the insufficient accuracy of the crossover determination whereas the calibration w.r.t. a reference model gives good results. [less ▲]

We propose a gossip-based distributed algorithm for Gaussian mixture learning, Newscast EM. The algorithm operates on network topologies where each node observes a local quantity and can communicate with other nodes in an arbitrary point-to-point fashion. The main difference between Newscast EM and the standard EM algorithm is that the M-step in our case is implemented in a decentralized manner: (random) pairs of nodes repeatedly exchange their local parameter estimates and combine them by (weighted) averaging. We provide theoretical evidence and demonstrate experimentally that, under this protocol, nodes converge exponentially fast to the correct estimates in each M-step of the EM algorithm. [less ▲]

Aujourd'hui l'analyse sociologique permet d'envisager la consommation de psychotropes par les seniors comme une caractéristique de nos sociétés modernes contemporaines. Le recours à ces médicaments est devenu l'une des clefs de la compréhension des comportements occidentaux où la recherche de bien-être physique, mental et social à tout prix est ressentie comme une nécessité avérée.Comment les consommateurs parviennent-ils à gérer leur consommation au point de la considérer comme non problématique ? Quelles attitudes pratiques et symboliques mettent-ils en œuvre pour y parvenir ? Est-il réellement possible de gérer son rapport à des produits intrinsèquement générateurs de dépendance ? Existe-t-il vraiment des personnes capables de contrôler leur consommation de psychotropes au point de la rendre compatible avec un mode de vie détaché de la dépendance à ce produit ? Existe-t-il une consommation invisible en raison même de son caractère non problématique pour les seniors ? Avec l'aide du psychotrope ne s'agit-il donc pas de rendre supportable et acceptable les effets du stigmate vécus par les seniors qui glissent peu à peu hors de la sphère productive ? La prescription de ces médicaments n'amène-t-elle pas à traduire des défaillances personnelles, des problèmes d'ordre social en besoin de solutions biomédicales ? Au-delà de cette médicalisation, ne doit-on pas également voir ces substances comme des moyens permettant de mieux répondre à la demande de performance définissant la normativité contemporaine ? Cette consommation ne révèle-t-elle pas une attitude de démission thérapeutique de la part des professionnels de la santé ? Les objectifs de ce travail ont été d’analyser les valeurs attribuées aux psychotropes, à la dépendance et le sens que les consommateurs et les consommatrices ayant une trajectoire continue ou occasionnelle donnent aux recours à ces médicaments.

An autonomous system able to construct its own navigation strategy for mobile robots is proposed. The navigation strategy is molded from navigation experiences (succeeding as the robot navigates) according to a classical reinforcement learning procedure. The autonomous system is based on modular hierarchical neural networks. Initially the navigation performance is poor (many collisions occur). Computer simulations show that after a period of learning the autonomous system generates efficient obstacle avoidance and target seeking behaviors. Experiments also offer support for concluding that the autonomous system develops a variety of object discrimination capability and of spatial concepts. [less ▲]

We describe Utile Coordination, an algorithm that allows a multiagent system to learn where and how to coordinate. The method starts with uncoordinated learners and maintains statistics on expected returns. Coordination dependencies are dynamically added if the statistics indicate a statistically significant benefit. This results in a compact state representation because only necessary coordination is modeled. We apply our method within the framework of coordination graphs in which value rules represent the coordination dependencies between the agents for a specific context. The algorithm is first applied on a small illustrative problem, and next on a large predator-prey problem in which two predators have to capture a single prey. [less ▲]

In den letzen Jahrzehnten ist eine Vielzahl von Modellen zur methodischen Unterstützung des Produktentwicklungsprozesses (PEP) entstanden. Diese präskriptiven Modelle beinhalten oft den impliziten Anspruch, in jeder Branche und auf die Entwicklung jeder Art von Produkten anwendbar zu sein. Um dem gerecht zu werden, beschreiben die Modelle den PEP auf einem relativ abstrakten Niveau. Eine Anpassung an den Kontext der Produktentwicklung erfolgt in der Regel nicht. Existierende Ansätze ermöglichen eine Analyse des Kontexts aus verschiedenen Blickwinkeln, bieten jedoch keine konkreten Vorschläge, wie diese Analyse in den Prozess der Produktentwicklung einfließen kann. Welche Auswirkungen ausgewählte Kontextfaktoren auf tatsächliche PEP haben, geht aus einer schriftlichen Befragung von 1000 deutschen Unternehmen des produzierenden Gewerbes hervor. Es werden die Grundlagen einer Vorgehensweise beschrieben, welche basierend auf dem Kontext der Produktentwicklung die Gestaltung effektiver, effizienter, transparenter und methodisch unterstützter Produktentwicklungsprozesse ermöglichen soll.

Design flaws often become apparent at a time when the product is already in use and its development process, which in many cases includes extensive testing of parts, components and prototypes, is considered complete. Such flaws may reach from poor ergonomics to the total failure of the product. Often, especially when user safety is at risk, design flaws are so severe that companies are forced to announce a product callback. Petroski suggests that many (if not most) products, which we are familiar with today, have a long history of previously flawed designs [3]. This implies that designers did indeed learn from design flaws in both senses of the word “learn”: discovering the flaw and utilizing the knowledge gained about it to find a solution. As far as discovering a design flaw is concerned, it can be assumed that the feedback from those who interact with the physical products in practice – the individuals who maintain, repair, recycle but essentially use the products – plays an important role. In their previous work, the authors pointed out hat this feedback information could not only be vital for identifying potential product hazards but helps designers to review the effects of their design measures and therefore to improve their products from generation to generation [4]. In order to obtain a better understanding of how designers learn from design flaws, a mail survey was conducted that aimed at investigating company-, process- and product-related factors of this phenomenon and to answer (among others) the following research questions: • To what extent are design flaws of a company’s (or a competitor’s) product a driving force in the development of new products? • How do the designers of a company become aware of design flaws of their products? • How successful are companies in correcting design flaws? • How do successful and unsuccessful companies differ in terms of size, activity profile of their designers and characteristics of their products? • What are possible factors that influence the success in correcting a design fault?

We present a simple randomized POMDP al gorithm for planning with continuous actions in partially observable environments. Our algorithm operates on a set of reachable belief points, sampled by letting the robot interact randomly with the environment. We perform value iteration steps, ensuring that in each step the value of all sampled belief points is improved. The idea here is that by sampling actions from a continuous action space we can quickly improve the value of all belief points in the set. We demonstrate the viability of our algorithm on two sets of experiments: one involving an active localization task and one concerning robot navigation in a perceptually aliased of fice environment.

Un nombre considérable d’études menées dans différents champs de la psychologie ou en ergonomie ont permis de mettre en évidence le caractère spécifique et contextualisé de l’activité professionnelle et de la compétence. Toutefois, cette notion de contexte de travail, largement présente dans la littérature, demeure encore largement absente des pratiques de mobilité professionnelle. Le travail présenté s’appuie sur l’hypothèse générale selon laquelle l’analyse et la prise en compte des contextes de travail peut améliorer l’efficacité des démarches d’aide à la mobilité professionnelle. Cette recherche a commencé par la mise au point, à partir de l’analyse de différents types d’emplois, d’une première typologie d’éléments de contexte susceptibles de jouer un rôle dans la mobilité. Ensuite, ces éléments de contexte ont été intégrés dans une méthodologie « systématique » d’aide à la mobilité intégrant la prise en compte du contexte dans l’analyse de l’expérience. Une étude de validation a été menée auprès de 68 personnes salariées d’entreprises de travail temporaire, 39 personnes suivies par divers centres de bilan et d’orientation et 10 personnes salariées d’une grande entreprise industrielle ; un suivi de ces personnes est effectué. Les données fournies par cette étude confirment l’intérêt qu’il y a à prendre en compte l’expérience du contexte pour la construction de parcours professionnels. [less ▲]
