Les ressources limitées des projets de conception incitent souvent à appliquer des méthodes UX rapides, low-cost, « quick & dirty ». Mais le « guerilla UX » peut aussi être « quick » sans être « dirty », être inspirant, et constituer une alternative valide aux méthodes traditionnelles de design UX. Au-delà des célèbres tests utilisateurs à la mode Starbucks, cette conférence vous présentera de nombreuses alternatives guérilla aux entretiens, questionnaires, observations, en passant aussi par l’idéation, le storyboarding ou le maquettage. Une bonne dose d’inspiration pour se donner les moyens de faire de l’UX quand on n’en a pas les moyens ! [less ▲]

The Gram-negative beta-proteobacterium Zoogloea sp. LCSB751 (LMG 29444) was newly isolated from foaming activated sludge of a municipal wastewater treatment plant. Here, we describe its draft genome sequence and annotation together with a general physiological and genomic analysis, as the first sequenced representative of the Zoogloea genus. Moreover, Zoogloea sp. gene expression in its environment is described using metatranscriptomic data obtained from the same treatment plant. The presented genomic and transcriptomic information demonstrate a pronounced capacity of this genus to synthesize poly-β-hydroxyalkanoate within wastewater. [less ▲]

The role of molten iron and slag in the dripping zone of a blast furnace is very critical to reach a stable operational condition. The existence of several fluid phases and solid particles in the dripping zone of a blast furnace, makes the newly developed eXteneded Discrete Element Method (XDEM) as an Eulerian-Lagrangian approach, suitable to resolve the dripping zone of a blast furnace. In the proposed model, the fluid phases are treated by Computational Fluid Dynamics (CFD) while the solid particles are solved by Discrete Element Method (DEM). These two methods are coupled via momentum, heat and mass exchanges. The main focus of current study is to investigate the influence of packed properties such as porosity and particle diameters, calculated by the XDEM, on the fluid phases for isothermal. In order to present the capability of the XDEM for this application. The validity of the proposed model is demonstrated by comparing model prediction results with the available experimental data.

Employing computer-supported collaborative learning for cooperative problem solving or as the basis for a shared learning environment regularly entails arbitrary restrictions and requirements for the participants. Frequent interruptions to the individual’s and the group’s workflow due to transitions between data type-specific applications, the manual synchronization of one’s work, or the prerequisite of a constant server connection are common examples. In this paper, we propose the utilization of a distributed compound document authoring environment to address these issues and apply a user-centric rather than the traditional, system-focussed perspective on computer-supported collaborative learning. This includes fine-granular, real-time management and assessment functionalities for the supervisor as well as a responsive, unobtrusive and feature-rich work environment for the participants.

Collaborative document authoring between geographically distributed users is increasingly common in our professional and personal lives. Corresponding systems aim to allow for the involvement of locally unavailable specialists while connecting familiar single-user functionality with an accessible, distributed multi-user environment. However, considering the highly dynamic processing loads on modern machines, accounting for network inadequacies, and providing a user-adjustable, mainly interruption-free work environment still presents some challenges. To address these challenges, we integrated our fine-granular data model, concurrency-based command application, and data-type specific consistency management into a distributed authoring environment. The collaboration environment provides individual sites sufficient independence to allow the local users to adapt their work experience based on personal preference and other, machine-related factors. This paper discusses our approach for a responsive, yet unobtrusive and adaptable distributed compound document authoring environment with the focus on concurrent and mainly autonomous command application and consistency management.

Computer-supported collaborative learning scenarios provide an opportunity for the participants to develop their conceptual understanding of a topic in a shared e-learning environment. This requires the integration of collaborative and cooperative authoring functionality for a wide range of distinct types of data, including multimedia. However, restricting access to currently manipulated elements by the means of locks and requiring the user to manually initiate and manage the synchronization process are still common side-effects to this support. Allowing for predominantly unrestricted, interruption-free and non-destructive multimedia editing in a distributed collaborative learning environment thus still presents a challenge. We propose to address these issues by integrating a fine-grained data model, concurrency-based command processing, and a primarily autonomous consistency management approach. Distinct editing operations by individual participants define manipulations on data type-specific attributes, which form the basis for an up-to-date representation of the targeted multimedia assets. We utilize an advanced Compound Document System and accompanying data models to allow for a feature rich, yet responsive and unobtrusive collaboration environment. [less ▲]

The collaborative authoring of complex document structures by geographically distributed users is no longer a special case in today's global economy or people's personal lives. However, integrating single-user application responsiveness and feature sets with the additional demands and expectations presented towards distributed multi-user environments remains a challenge. Current solutions approaching this challenge almost exclusively rely on traditional, file-based data structures. This often introduces arbitrary workflow restrictions to the user and reduces the potential to benefit from an otherwise inherently concurrent system. Our distributed compound document authoring environment aims at addressing these challenges while providing system-level collaboration support to the user. We attain this through the close integration of a fine-grained data structure with a highly scalable, priority-based concurrency model for command distribution and application. This paper discusses our enhanced data representation and concurrency model together with the evaluation of their prototypical implementation. [less ▲]

While the study of human-machine interactions is fairly well established regarding usability dimensions, the approach of the user experience, more recent, incorporates new dimensions in order to bring to light on these interactions. This work takes part in this approach and aims to clarify the relationship between a non-functional quality and a functional quality of a system, the main effect of these qualities on the affects experienced during the interaction with the system and finally the effect of the system qualities on behaviours. A research information task on 4 Websites corresponding to both crossed variables, aesthetics (high vs low) and usability (high vs low), should allow us to explore these questions through self-reports measures and behavioural recording. In addition, we attempt to identify relevant indicators which have not been used much yet. This study is run on touch tablet computers on Windows systems. [less ▲]
