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.

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.

L’internationalisation des rapports juridiques conduit de plus en plus à une imbrication des systèmes juridiques et à la nécessité de reconnaître des institutions juridiques venus d’ailleurs. L’une de ces institutions, le trust, né dans le système de la common law, s’exporte de plus en plus dans les pays de tradition civiliste. Pour faciliter son acclimatation, la Convention de la Haye relative à la loi applicable au trust et à sa reconnaissance a été adoptée le 1er juillet 1985. Cette Convention entend à la fois permettre la reconnaissance de cette institution par des ordres juridiques qui ne la connaissent pas et fixer à l'égard des pays signataires la loi applicable au trust. A l’aube de sa ratification par la Suisse, des experts venus de différents pays se sont réunis à l’Institut suisse de droit comparé (Lausanne) le 18 mars 2005 pour partager les expériences nationales. Le présent ouvrage publie les rapports exposés à cette occasion. [less ▲]

Electron emission from surfaces due to interaction with charged particles and electromagnetic fields is a topic of research for over 100 years. In the past decade new developments in the production of ultrashort laser pulses (tau < 10 fs at a wavelength of lambda approximate to 750 nm) and of slow highly charged ions (HCI) have rendered these interactions to be remarkably similar. The description of electron emission in HO-surface interactions can therefore be transcribed to model and understand photoemission from surfaces interacting with ultrashort laser pulses. Examples will be presented for two model systems. (c) 2005 Elsevier B.V. All rights reserved. [less ▲]

OpenSST (Open Simple Secure Transaction) is a free software project and aims to create an efficient, open and secure alternative to the secure proprietary transaction protocol. OpenSST uses XML syntax to specify its message format, and relies on prevalent cryptographic algorithms to secure the transaction. OpenSST is designed to provide user with the guarantee on confidentiality, integrity, authenticity and non-repudiation. One feature of OpenSST's is that it defines a simple message structure so that it can easily be integrated into different usage frameworks. This paper mainly describes OpenSST's logic architecture and message format through an http-based prototype. [less ▲]

Our paper presents some results from a research on women's entrepreneurship in Belgium, which is part of a wider project called “Diane”, which took place within the framework of an equal opportunity action. We choose to expose one of the most interesting aspects of this research on women’s entrepreneurship : financing. The main question of our research was to enquire whether there are any specificities in the women’s entrepreneurship in Belgium as regards the financing of their firms. First, we investigated the amounts that female entrepreneurs invested for the start-up and development of their firms. Second, we aimed to determine which financing sources were used by female entrepreneurs. Finally, we enquired whether they had access to external financing, and more specifically to bank loans. Our results show that female entrepreneurs have mainly recourse to their personal savings or to family and friends’ loans to finance the company start-up and development. But they use also bank loans in a great extent for their firm launching. Nevertheless, it seems that they apply for bank loans only if they have no other choice, due to their strong risk-aversion and their lack of trust toward bankers. These reasons also lead them to invest lower amounts in the start-up and development of their companies. Female entrepreneurs face a lot of barriers to bank financing. There are several specific financing problems for female entrepreneurs, related to some of their firm’s characteristics, especially the field of activity and the size. Some gender characteristics can also be barriers to financing. On the basis of our results, we draw some recommendations for public authorities. [less ▲]

We give an interpretation of order invariant functions as scale independent functions for the aggregation on finite ordinal scales. More precisely, we show how order invariant functions can act, through discrete representatives, on ordinal scales represented by finite chains. In particular, this interpretation allows us to justify the continuity property for certain order invariant functions in a natural way. [less ▲]

In humans, neuroimaging studies have identified two major visual extrastriate areas presenting face-sensitive responses: in the inferior occipital cortex (‘occipital face area’, OFA), and the middle fusiform gyrus (the ‘fusiform face area’, FFA), with a right hemispheric dominance. It has been proposed that the OFA, located anteriorly to foveal V4v (Halgren et al., 1999), has a critical role in the early perception of facial features and provides the feedforward outputs to later stages of face processing in both the FFA and the STS (Haxby et al., 2000). However, we have recently reported a normal activation of the right FFA despite a lesion encompassing the region of the right OFA in a brain-damaged prosopagnosic patient, PS (Rossion et al., 2003), suggesting that the face-sensitive responses observed at the level of the OFA in normals may rather arise from feedback connections from the FFA. Here we provide complementary fMRI evidence supporting this view. First, the normal differential activation for faces and objects in the right FFA of PS was observed only for left visual field presentations and is thus unlikely to originate from contralateral intact regions of the occipital cortex (e.g. left OFA). Second, the time-course in the right FFA and left OFA of PS for centrally presented items suggests an earlier differential activity between faces and objects in the most anterior region, the FFA. Finally, we imaged another (prosop)agnosic patient (NS, Delvenne et al., 2004) with a lesion encompassing the right FFA but sparing all posterior visual areas, and failed to disclose any face-sensitive response in his nonetheless structurally and functionnally intact occipital cortex. Together, these findings illustrate the necessary role of both the right FFA and OFA for accurate face perception, and reinforce the hypothesis that a dominant (feedback) connection from the FFA to the OFA subtends face-sensitive responses observed in the latter area when processing faces.

We define an aggregation function to be (at most) k-intolerant if it is bounded from above by its kth lowest input value. Applying this definition to the discrete Choquet integral and its underlying capacity, we introduce the concept of k-intolerant capacities which, when varying k from 1 to n, cover all the possible capacities on n objects. Just as the concepts of k-additive capacities and p-symmetric capacities have been previously introduced essentially to overcome the problem of computational complexity of capacities, k-intolerant capacities are proposed here for the same purpose but also for dealing with intolerant or tolerant behaviors of aggregation. We also introduce axiomatically indices to appraise the extent to which a given capacity is k-intolerant. [less ▲]

In the framework of cooperative game theory and multicriteria decision making, the concept of interaction index, which can be regarded as an extension of that of value, has been recently proposed to measure the interaction phenomena among players or criteria. Axiomatizations of two classes of interaction indices, namely probabilistic interaction indices and cardinal-probabilistic interaction indices, generalizing probabilistic values and semivalues, respectively, are first proposed. Three existing instances of cardinal-probabilistic interaction indices encountered thus far in the literature are also axiomatized. [less ▲]

Both rely on a credibility evaluation domain using the rational in- terval [−1, 1] where the sign carries a split truth/falseness denotation. The first technique implements the classic min and max operators where as the second technique implements Bochvar-like operators. Main interest in the communica- tion is given to the concept of natural fuzzification of a propositional calculus. A formal definition is proposed and the demonstration that both fuzzification techniques indeed verify this definition is provided. [less ▲]

The interactive and multi-protagonist (IMP) film is a novel concept that extends the hypermovie genre. The IMP film is based on the common structures of linear narrative storytelling and provides the viewer with various decision points within the evolving story that support an active choice among different protagonists’ views. The viewer will thus be elevated to the role of a decision maker. They individually and actively determine the story flow. The IMP film substantially extends the currently offered interactivity of DVDs which is primarily limited to navigation. The production process of an IMP film will be illustrated by presenting Deine Wahrheit (Your Truth), a DVD-based movie. The results of an empirical study support the advantages of the IMP film compared to a traditional single-protagonist version of the film. The potential of the IMP film as a new genre in hypermovie will be discussed. [less ▲]

The influence of a carrier supply layer on the electrical properties of MSM diodes based on AlGaN/GaN HEMT layer structures is investigated. The voltage dependence of the Schottky contact capacitance allows the use of the device as varactor diode with CMAX / CMIN ratios up to 17, tuneable by contact geometry. The carrier supply doping determines the sheet carrier density of the twodimensional electron gas channel, which is responsible for the transition voltage and the series resistance of the MSM diode. A device based on the highest doped layer structure shows a cutoff frequency as high as 65 GHz. [less ▲]

The small signal S-parameter and load pull measurements on AlGaN/GaN HEMTs with different doping densities are reported. The cut-off frequencies ft and fmax of 38 and 67 GHz respectively, and the maximal output powers of 4.9 and 3.8 W/mm at 2 and 7 GHz respectively, were achieved. The parameter extraction from small signal S-parameters shows an increase of gate-source capacitance and transconductance with the doping concentration and hence its influence on small signal (ft and fmax) and power performance.

La doctrine classique ne semble avoir jamais été véritablement à l'aise avec la notion de capital social. Appréhendée de façon abstraite, exposée de façon sommaire dans les manuels de référence, elle ne semble pas occuper dans les réflexions des auteurs la place qu'elle pourrait mériter. Car dans la pratique des affaires, la notion de capital social demeure une référence extrêmement forte tant pour les comptables que pour les juristes. Cependant a-t-elle encore une véritable signification ? Et si oui, laquelle ? S'agit-il, comme beaucoup le suggèrent d'une notion dépassée ? A supposer que ce soit le cas, peut-on envisager d'aller au-delà et puiser dans les enseignements du droit comparé des techniques alternatives ? Ces questions premières sont au cour de cet ouvrage issu des travaux d'un colloque qui s'est tenu en octobre 2003 et qui a cherché à dresser un bilan de l'état du droit qui régit le capital social et ses mutations.

We present an approximate POMDP solution method for robot planning in partially observable environments. Our algorithm belongs to the family of point-based value iteration solution techniques for POMDPs, in which planning is performed only on a sampled set of reachable belief points. We describe a simple, randomized procedure that performs value update steps that strictly improve the value of all belief points in each step. We demonstrate our algorithm on a robotic delivery task in an office environment and on several benchmark problems, for which we compute solutions that are very competitive to those of state-ofthe -art methods in terms of speed and solution quality.

Coordinationgraphsprovideatractableframe- work for cooperative multiagent decision making by decom- posing the global payoff function into a sum of local terms. In this paper we review some distributed algorithms for ac- tion selection in a coordination graph and discuss their pros and cons. For real-time decision making we emphasize the need for anytime algorithms for action selection: these are algorithms that improve the quality of the solution over time. We describe variable elimination, coordinate ascent, and the max-plus algorithm, the latter being an instance of the be- lief propagation algorithm in Bayesian networks. We discuss some interesting open problems related to the use of the max- plus algorithm in real-time multiagent decision making. [less ▲]

Works centered on the search for a quality of life (QoL) definition have mostly privileged the individual interviews. No methodology has compared yet the quantitative production of items resulting from individual interviews with those from focus groups, concerning a lower limbs osteo-arthritis QoL. Purpose: To compare methods of item generation for methods : 2 individual interviews and 2 focus groups and to identify the pertinence of a theoretical construit of QoL. Methods: All methods compared relied on extraction of verbatim collected during tape recorded interviews, transcripted and analysed by 3 teams of health psychologists and sociologists independently. The 4 methods compared were interviewed with interview guide with OA patients in 1) focus group, 2) individual semi-structured interview and 3) using a cognitive interview technique to enhance memories. Using the final scale as a gold standard, the sensitivity and specificity, i.e. the contribution of each method to the scale, were estimated. Results: 66 individual and focus interviews were conducted with 96 OA patients. After exclusion of speeches not related to QoL (i.e. satisfaction, coping, locus of control), 80 items were identified relevant. With patients, focus group produced 74% of the items, while both individual methods contributed 100% of resulting items and none item except subject. Focus group methods contributed some themes but individuals gave more in depth information. Traditional semi-structured interviews contributed to known QoL themes and to items on the feeling of being embarrassed for people to be seen, to ask for help and to annoy close relatives, while cognitive interviews provided more fine tuned items on exchanges with and perception by others about their condition, as well as perspective in life and fears from future dependency. Conclusion. The selected method is relevant to explore the theoretical construit of QoL. One can recommend to use patients’ semi-structured interviews with a traditional or a cognitive technique, conducted by interviewers preferably non-specialist of the condition explored. Perspectives. The question is then what is the influence of the topic on the method to be retained? [less ▲]

We present some compositions of clones of Boolean functions that imply factorizations of ?, the clone of all Boolean functions, into minimal clones. These can be interpreted as representation theorems, providing representations of Boolean functions analogous to the disjunctive normal form, the conjunctive normal form, and the Zhegalkin polynomial representations.

Der interaktive Perspektivenfilm (IPF), eine besondere Form des Hyperfilms, unterstützt unter Beibehaltung der bewährten linearen Erzählweise des Mediums Film zu verschiedenen Zeitpunkten des Verlaufs einer Geschichte die aktive Auswahl aus konkurrierenden Erzählperspektiven. Der Zuschauer wird auf diese Weise zum Entscheidungsträger und Gestalter des Informationsflusses. Die bisher weitestgehend auf Navigation reduzierte Interaktivität des Mediums Video-DVD wird somit wesentlich erweitert. Anhand des Filmprojekts „Deine Wahrheit“ wird der Produktionsprozess eines IPF von der Konzeption der Charaktere über das Verfassen des Drehbuchs und der digitalen-technischen Produktion und Nachbearbeitung des Filmmaterials sowie dem abschließenden DVD-Authoring vorgestellt. Belege für den Mehrwert des IPF resultieren aus dem empirischen Vergleich mit einer herkömmlichen, perspektivisch-linearen Version des Films. Das Potenzial dieses neuen Genres wird diskutiert.
