In the areas of design, especially in architectural design, collaboration has become an important challenge. The specialization of skills increase, work teams are more and more extensive and the geographic distance between them increases too. The economic and ecological stakes related to remote collaboration are an evidence. This context involves the need to support most efficiently possible remote working meetings. We present the Distributed Collaborative Digital Studio (DSDC), a tool designed to recreate, in distant situations, the context of copresence meetings. This shared environment is created in the “invisible computer” approach. The idea is that the tool should disappear from user’s consciousness. Indeed, creative design activities require some fluidity in their process. Therefore, any involuntary interruption created by the system can potentially brake creativity. In this perspective, we investigate specifically the “invisibility” of our environment. To do this, we propose a framework for the operationalization of the concept and a methodology to test the system invisibility. This methodology was applied through a case study consisting of a corpus of 12 hours of remote collaborative design sessions with the DSDC. We highlight the learning effects while using our system, conclude on its effectiveness and discuss our methodology. [less ▲]

This paper is a tentative assessment of the Rawls-Machiavelli program by Philippe Van Paris, who proposes that justice is the main goal of political action (in a Rawlsian perspective) and democracy is only instrumental (the Machiavellian part of the program). The paper adresses three questions to the proposal of Philippe Van Paris : 1) Can democracy be properly defined without a condition of public debate ? 2) Don't "realistic politics" underestimate the margin of possibility we have to change "what people are" and 3) If people overemphasize that part of their interests which is linked to their ethno-national belonging, is it not because alternative political offer is not differentiated enough ?

The authors consider a power system composed of several non-synchronous AC areas connected by a multiterminal high-voltage direct current (HVDC) grid. In this context, the authors propose a distributed control scheme that modifies the power injections from the different AC areas into the DC grid so as to make the system collectively react to load imbalances. This collective reaction allows each individual AC area to downscale its primary reserves. The scheme is inspired by algorithms for the consensus problem extensively studied by the control theory community. It modifies the power injections based on frequency deviations of the AC areas so as to make them stay close to each other. A stability analysis of the closed-loop system is reported as well as simulation results on a benchmark power system with five AC areas. These results show that with proper tuning, the control scheme makes the frequency deviations converge rapidly to a common value following a load imbalance in an area. [less ▲]

The additional energy spread due to sample porosity was implemented in the SIMNRA simulation code, version 6.60 and higher. Deviations of the path length and energy loss distributions from the ones expected from a Poisson distribution of the number of traversed pores are taken into account. These deviations are due to the interaction of pores at higher pore concentrations by overlap or blocking. The skewnesses of the energy distributions are approximated by two-piece normal distributions with identical first three moments. Propagation of porosity-induced energy spread in thick layers is taken into account. Calculated results are compared to experimental data obtained with thin TiO2 mesoporous films measured by Rutherford backscattering (RBS),transmission electron microscopy (TEM), and atmospheric poroellipsometry.

Model parameterization through adjustment to field data is a crucial step in the modeling and the understanding of the drainage network response to tectonic or climatic perturbations. Using as a test case a data set of 18 knickpoints that materialize the migration of a 0.7-Ma-old erosion wave in the Ourthe catchment of northern Ardennes (western Europe), we explore the impact of various data fitting on the calibration of the stream power model of river incision, from which a simple knickpoint celerity equation is derived. Our results show that statistical least squares adjustments (or misfit functions) based either on the streamwise distances between observed and modeled knickpoint positions at time t or on differences between observed and modeled time at the actual knickpoint locations yield significantly different values for the m and K parameters of the model. As there is no physical reason to prefer one of these approaches, an intermediate least-rectangles adjustment might at first glance appear as the best compromise. However, the statistics of the analysis of 200 sets of synthetic knickpoints generated in the Ourthe catchment indicate that the timebased adjustment is the most capable of getting close to the true parameter values. Moreover, this fitting method leads in all cases to an m value lower than that obtained from the classical distance adjustment (for example, 0.75 against 0.86 for the real case of the Ourthe catchment), corresponding to an increase in the non-linear character of the dependence of knickpoint celerity on discharge [less ▲]

Improvements on the Liége cyclotron have yielded an energy resolution comparable to that of classic electrostatic accelerators. The latest upgrades of the High-Energy High-Resolution beam line (HE-HR) are presented which consist of the addition of both a new extraction nozzle for non-invasive in-air measurements and a new particle-detection setup developed to take full advantage of the increased probed thickness with depth sensitive analytical methods. The suitability of the new setup and the advantages provided by the larger flexibility in choosing both the proper particle with an extended energy available will be illustrated by discussing latest results of studies recently led on Roman gilding techniques on cultural heritage artifacts by means of “High-Energy” alpha backscattering spectrometry combined with PIXE.

A subproblem technique is applied to dual thin shell finite element formulations. Both the magnetic vector potential and magnetic field formulations are considered. The subproblem approach developed herein couples three problems: a simplified model with only inductors, a thin region problem using approximate interface conditions and a correction problem to improve the accuracy of the thin shell approximation, in particular near their edges and corners. Each problem has its own geometry and is solved on its associated finite element mesh. [less ▲]

Although Bharati Mukherjee is famous, or rather infamous, for her shameless embrace of America and its melting-pot ideology, in Desirable Daughters India, the homeland, is unexpectedly made to re-enter the stage of immigrant identity construction. In many respects it would seem that it has now become untenable to represent immigrant identity in terms of a one-directional movement from “India” to “America.” In Desirable Daughters the rise of India, the accelerated time/space compression of late capitalism, the post-90s paradigm shift in matters of transnational migration, the emphasis on return migrations and the emergence of a new global interaction indeed dramatically outflank Mukherjee’s previous narrative of American “exceptionalism” – which suddenly seems dated by comparison. By portraying the complex transnational network of connections operating between RIs (Resident Indians) and NRIs (Non Resident Indians), Mukherjee’s book gestures towards the “de-spatialization” of immigrant identity construction and its consequent “re-metaphorization” in terms of “time zones.” What is more, the increasingly compelling influence of contemporary India on the Indo-American diasporic subjectivity marks a “back to the future” return of the repressed which temporally repositions migrant identity between a ghostly time of repetition and a “hauntology” of new becomings. What Mukherjee suggests, I will contend, is that immigrant agency and self-fashioning cannot be associated anymore with the “pioneering spirit” of forward-looking characters that discard their “Indianness” upon (geographical) entry into the West. In my reading of Desirable Daughters the protagonist’s zigzagging path to self-transformation will be emphasized, so that it will become apparent that time has become the fourth space through which new spaces for diasporic identity can be renegotiated.
