    Sujet: History & Archaeology
    Description: Cet article propose une étude des communautés cam et malaises du Cambodge et de Cochinchine (Sud Viêt Nam) pendant la période coloniale à travers l’examen d’un corpus de documents administratifs tirés des Archives de la Résidence Supérieure du Cambodge. Les documents étudiés mettent en valeur plusieurs aspects de la vie quotidienne des Cam et des Malais pendant toute la période du Protectorat et nous apportent de précieuses informations sur les difficultés auxquelles se sont heurtés les fonctionnaires de l’administration française pour définir les questions d’identité, de nationalité et de statut légal des Cam et des Malais du Cambodge. Les archives nous offrent également des informations sur les migrations des Cam et des Malais et les tentatives de l’administration pour imposer une régulation. Enfin, les archives nous apportent des renseignements inédits sur les conflits religieux intracommunautaires qui ont secoué les communautés cam et malaises ainsi que sur la question de la diffusion des mouvements réformistes religieux malais au Cambodge. Cam and Malays in Cambodia and Cochinchina Seen Through Colonial Archives (1859-1954). The aim of this paper is to study the Cam and Malay communities in Cambodia and Cochinchina (South Vietnam) during the colonial period through the analysis of a corpus of administrative documents belonging to the Archives of the Résidence Supérieure in Cambodia. These documents highlight several aspects of the daily life of Cam and Malays during the entire Protectorate period and provide precious data regarding the difficulties encountered by the civil servants in the French administration in order to define questions of identity, nationality and legal status of the Cam and Malays living in Cambodia. Archives also offer information on the migrations of the Cam and Malays, as well as the administration’s efforts to impose a regulation. Lastly, the archives offer new insights on the religious conflicts inside the communities, that rocked the Cam and Malay communities, and also regarding the diffusion of Malay religious reformist movements in Cambodia.

    Titre: Note sur les inscriptions en cam du pāḷāt' Tut, estampeur d'Étienne Aymonier
    Auteur: Weber, Nicolas
    Sujet: History & Archaeology
    Description: Cet article présente trois courtes inscriptions rédigées en langue cam et adoptant la graphie du cam moderne en usage au Cambodge par les Cam de la diaspora. Ces trois inscriptions ont été réalisées par l'un des collaborateurs cam d'Etienne Aymonier, nommé Tut, à l'occasion de la recherche de stèles qu'il mena au Cambodge et de leur estampage. This paper presents three short inscriptions written in Cham language with the script used in Cambodia by Chams in the diaspora. These three inscriptions were carved by a man called Tut, one of Etienne Aymonier's Cham collaborators during his campaign to search for and take estampages of inscriptions in Cambodia.

The induced voltages caused by the switching of magnetic field gradients and rectified radio frequency (RF) pulse were measured, along with the AIMD stimulations. Materials and methods An MRI-compatible voltage probe with a bandwidth of 0--40 kHz was designed. Measurements were carried out both on the bench with an overvoltage protection circuit commonly used for AIMD and with a pacemaker during MRI scans on a 1.5 T (64 MHz) MR scanner. Results The sensor exhibits a measurement range of[+ or -]15 V with an amplitude resolution of 7 mV and a temporal resolution of 10 A[micro]s. Rectification was measured on the bench with the overvoltage protection circuit. Linear proportionality was confirmed between the induced voltage and the magnetic field gradient slew rate. The pacemaker pacing was recorded successfully during MRI scans. Conclusion The characteristics of this low-frequency voltage probe allow its use with extreme RF transmission power and magnetic field gradient positioning for MR safety test of AIMD during MRI scans.

    Titre: Modeling and optimization of a latched charge pump loaded by a resistive circuit
    Auteur: Heitz, Jérôme; Frick, Vincent; Dumas, Norbert; Weber, Nicolas; Lallement, Christophe; Hébrard, Luc
    Sujet: DC–DC converter ; Dickson charge pump ; Latched charge pump ; High-voltage CMOS technology
    Description: Many successive improvements of the charge pump (CP) principle introduced by Dickson have paved the way to efficient integrated DC–DC converters. One of the most used CP is the bootstrap Dickson CP, or its double version. However, the best achievement is certainly the latched charge pump (LCP). Indeed, as in a Dickson pump, it makes use of pump capacitors in parallel, lowering its sensitivity to parasitic capacitors and allowing high pump gain. As a double structure, it also exhibits a low output voltage ripple. But one of its best advantages is that it only requires a simple two-phase clock and thus less transistors than the bootstrap CP. Yet, few studies have been published on the LCP. Therefore, this paper focuses on the modeling and design of LCPs. It provides the designer with a simple and robust way to quickly design such a pump when it is meant to be loaded with a resistor and has to deliver a steady-state current. Its optimization in terms of silicon area, efficiency or efficiency-to-area ratio is also discussed. It is shown than contrary to all the previous studies on CP optimization, the total area of the pump, i.e. the area of the capacitors but also the area of the switching transistors have to be considered for a better optimization. Experimental results obtained on a 22 V output voltage CP able to deliver 42 μA, designed in a high-voltage 0.35 μm CMOS technology, are also given.

    Description: Neural network frameworks such as PyTorch and TensorFlow are the workhorses of numerous machine learning applications ranging from object recognition to machine translation. While these frameworks are versatile and straightforward to use, the training of and inference in deep neural networks is resource (energy, compute, and memory) intensive. In contrast to recent works focusing on algorithmic enhancements, we introduce BrainSlug, a framework that transparently accelerates neural network workloads by changing the default layer-by-layer processing to a depth-first approach, reducing the amount of data required by the computations and thus improving the performance of the available hardware caches. BrainSlug achieves performance improvements of up to 41.1% on CPUs and 35.7% on GPUs. These optimizations come at zero cost to the user as they do not require hardware changes and only need tiny adjustments to the software. Comment: Technical Report, 13 pages

    Titre: Detail-Preserving Pooling in Deep Networks
    Auteur: Saeedan, Faraz; Weber, Nicolas; Goesele, Michael; Roth, Stefan
    Sujet: Computer Science - Computer Vision And Pattern Recognition ; Computer Science - Learning
    Description: Most convolutional neural networks use some method for gradually downscaling the size of the hidden layers. This is commonly referred to as pooling, and is applied to reduce the number of parameters, improve invariance to certain distortions, and increase the receptive field size. Since pooling by nature is a lossy process, it is crucial that each such layer maintains the portion of the activations that is most important for the network's discriminability. Yet, simple maximization or averaging over blocks, max or average pooling, or plain downsampling in the form of strided convolutions are the standard. In this paper, we aim to leverage recent results on image downscaling for the purposes of deep learning. Inspired by the human visual system, which focuses on local spatial changes, we propose detail-preserving pooling (DPP), an adaptive pooling method that magnifies spatial changes and preserves important structural detail. Importantly, its parameters can be learned jointly with the rest of the network. We analyze some of its theoretical properties and show its empirical benefits on several datasets and networks, where DPP consistently outperforms previous pooling approaches.
