Collaborative Reverse Engineering Design Experiment Using PLM Solutions
No full textThe current climate of economic competition forces businesses to adapt to the expectations of their customers. To achieve this, in spite of the increasing complexity of mechanical systems, it becomes necessary, amongst other things, to reduce design time. Faced with new challenges, practices in design training must evolve to allow students to be mindful of these evolutions as well as to be able to manage projects in these new work environments. After presenting a state of the art of collaborative tools used in product design, our paper presents an experiment focusing on the reverse engineering of a complex mechanical product. This experiment was carried out between two centers of the Arts et Métiers ParisTech School of Engineering, located in Paris and Angers.Weanalyze the results obtained in this experiment and propose a collaborative environment that is well suited to our needs for design education, based on ‘‘Product Lifecycle Managament’’ (PLM) concepts. Finally, we present some modifications in collaborative design courses for our students, and we implement network modifications in order to significantly improve the ease of use of the design environment
Dimerization and effective decoupling in two spin-1 generalizations of the spin-1/2 Majumdar-Ghosh chain
No full textWe perform a systematic DMRG investigation of the two natural spin-1 generalizations of the spin-1/2 Majumdar-Ghosh chain, the spin-1 J(1)-J(2) Heisenberg chain, where J(2) is a next-nearest-neighbor Heisenberg coupling, and the spin-1 J(1)-J(3) model, where J(3) refers to a three-site interaction defined by J(3)[(Si-1 . S-i)(S-i . Si+1) H.c.]. Although both models are rigorously equivalent to the Majumdar-Ghosh chain for spin 1/2, their physics appears to be quite different for spin 1. Indeed, when all couplings are antiferromagnetic, the spin-1 J(1)-J(2) model undergoes an effective decoupling into two next-nearest-neighbor (NNN) Haldane chains upon increasing J(2), while the J(1)-J(3) chain undergoes a spontaneous dimerization similar to the spin-1/2 Majumdar-Ghosh chain upon increasing J(3). By extending the phase diagram to all signs of the couplings, we show that both the dimerized and the NNN-Haldane phase are actually present in the J(1)-J(3) model, the former one adjacent to the Haldane one, the latter to the ferromagneric one, with an Ising transition between them. By contrast, the J(1)-J(2) chain only has a NNN-Haldane phase between the Haldane phase and the ferromagnetic phase for positive J(2). In both cases, our DMRG data are consistent with a continuous Kosterlitz-Thouless transition between the NNN-Haldane and the ferromagnetic phases.CTM
Eight-vertex criticality in the interacting Kitaev chain
No full textWe show that including pairing and repulsion into the description of one-dimensional spinless fermions, as in the domain wall theory of commensurate melting or the interacting Kitaev chain, leads, for strong enough repulsion, to a line of critical points in the eight-vertex universality class terminating floating phases with emergent U (1) symmetry. For nearest-neighbor repulsion and pairing, the variation of the critical exponents along the line that can be extracted from Baxter's exact solution of the XYZ chain at J(x) = -J(z) is fully confirmed by extensive density matrix renormalization group (DMRG) simulations of the entire phase diagram, and the qualitative features of the phase diagram are shown to be independent of the precise form of the interactions.CTM

The empire of India: The great unrest
No full textThis is an editorial discussing the British occupation of India and the Nationalist Movement. It specifically addresses the discontent in India and its causes, the goals of the Nationalist Movement, some of the measures British officials have taken to quell it, and the nationalist boycott of all non-Indian made and produced goods.Research project undertaken by the University of the Fraser Valley South Asian Studies Institute, formerly the Centre for Indo-Canadian Studies in 201
