We report on the dc and RF performance of HEMT’s based on the Al-free material system InP/InGaAs/InP. These structures were grown by LP-MOCVD using a nitrogen carrier. The influence of gate length and channel composition on the performance of these devices is investigated.We demonstrate that optimum dc and RF performance using highly strained channels can be obtained only if additional composite channels are grown. The cutoff frequencies fT =160 GHz and fmax=260 GHz for a 0.1- um T-gate device indicate the suitability of our devices for W-Band applications. [less ▲]

The Bond series has not only traditionally made use of the Gothic mode, but it has also influenced the Gothic in its turn. Taking its cue from the Alan Moore’s graphic novel The League of Extraordinary Gentlemen (vol.1, 1999), its filmic adaptation (2003) and the film Van Helsing (2004), this essay discusses the ways in which the character of Bond and the Bond formula have made their entry into contemporary Gothic visual culture. As the many intertextual references to Bond in both versions of The League of Extraordinary Gentlemen make clear, James Bond has become a role model, a figure other popular-cultural texts draw on and fall back to in gestures of either imitation, subversion or parody. Furthermore, the references to Bond serve to link the texts mentioned above, which are all set in the late Victorian Age, to the popular culture of late the 20th and early 21st centuries. Concentrating in more detail on Van Helsing, which establishes an exceptionally prominent Bondian subtext, this essay reads the film as conflating the narrative and ideological scripts of both Bond and Stoker’s Dracula. As argued in this essay, the combined use of Bond and Gothic mode enables the film to criticise the re-introduction of the categories of good and evil as an allegedly stable binary difference into early 21st-century western Realpolitik.

The curators of the ninth Lyon Biennial approached the task of mapping the moment in contemporary art playfully: by commissioning a polyphonic history and geography book. With 70 "players" from around the world, the "game" of how to define the decade unfolded via a series of delegations, invitations and programs in which artists proposed their responses and critics and curators sequenced and challenged them, in turn suggesting artists of their own. Reframing the unfolding present from within, creatively rethinking the role of the artist as well as that of serious play, and reconsidering the now-ubiquitous and decreasingly authoritative biennial exhibition, these myriad voices, framed by only a few rules, became participants in an exercise in collective self-determination. This lavishly illustrated publication, designed by the renowned Parisian firm M/M and edited by Biennial curators Hans Ulrich Obrist and Stéphanie Moisdon, includes previously unpublished essays by Michel Houellebecq, Okwui Enwezor and Ralph Rugoff, and functions as a manual for "a decade yet to be named a present that is endlessly arriving."

On 1st February 2011, 1.8% of the population of the Grand Duchy were in an institutional household (9073 persons). Among those persons, we find mainly people living in old people’s home (56.1% of collective households), then people living in home for adults (10.4%), children living in home for child (5.8%), military living in barracks (5.5%) and those in prison (5.0%). If everyone may need at a time in his life to stay in a collective household, two age’s categories are particularly relevant: the elderly and young adults. [less ▲]

In 1920 publiseerde Prandtl een artikel over het bezwijken van een materiaal onder een strookbelasting. De bezweken grondmoot is hierbij verdeeld in drie zones, die tezamen de zogenoemde Prandtl-wig vormen. Prandtl heeft nooit aan de funderingstechnische toepassing gedacht, maar geotechnici vertalen deze oplossing nu als een analytische oplossing voor de draagkracht van de grond onder een strookfundering. Deze oplossing is uitgebreid door Reissner met een bovenbelasting naast de funderingsstrook en door Keverling Buisman en Terzaghi voor het grondgewicht. Terzaghi schreef dit als eerste met drie gescheiden draagkrachtfactoren en Meyerhof als eerste met “inclinatie-” en “shape” factoren, voor de drie afzonderlijke draagkrachtcomponenten; cohesie, bovenbelasting en het grondgewicht. Deze schrijfwijze werd later door Brinch Hansen overgenomen. In dit artikel zijn een groot aantal numerieke berekeningen gemaakt om het bezwijkmechanisme van de Prandtl-wig en de bijbehorende draagkrachtfactoren te controleren. Het blijkt dat het Prandtl-wig bezwijkmechanisme juist is, maar niet in alle gevallen. Ook blijkt dat de analytische oplossingen voor de draagkrachtfactoren die tegenwoordig worden gebruikt, alleen juist zijn voor grond met een onrealistisch hoge dilatantiehoek. [less ▲]

The biggest problem for a shallow foundation, just as any other type of foundation, is a failure due to an overestimation of the bearing capacity. This means that the correct prediction of the bearing capacity of the foundation is often the most important part of the design of a civil structure. That is why the publication of Prandtl in 1920 about the hardness of a plastic body, was a major step in solving the bearing capacity of shallow foundations, although it is well possible that he never realised this, because his solution was not made for civil engineering purposes, but for mechanical purposes. Over the last 100 year, a lot of extensions have been made, for example with inclination factors and shape factors, and many laboratory experiments have been done and also many numerical calculations have been made. Some even try to extrapolate the failure mechanism for shallow foundations to the failure mechanism around the tip of a pile. All this scientific work leads back to the first publication made by Ludwig Prandtl in 1920. This intermediuate report “100 Year Prandtl’s wedge” has been made for all those who are interested in these fundamentals of foundation engineering and their history. [less ▲]
