Hayes (1901-1964) auditioned and directed youth to perform in folk dance, music, and folk and ballad singing. The jamboree was held in the Asheville City Auditorium (now known as Thomas Wolfe Auditorium) from 1948 to 1973, and Hayes’ wife, Leona Trantham Hayes (1913-1989) continued to direct the program after his death in 1964. Hubert Hayes was an author, playwright, and alumni of Duke University
Microprocessor energy characterization and optimization through fast, accurate, and flexible simulation
Full text linkThesis (S.M.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2001.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Includes bibliographical references (p. 99-102).Energy dissipation is emerging as a key constraint for both high-performance and embedded microprocessor designs, requiring computer architects to consider energy in addition to performance when evaluating design decisions. A major limitation is the general difficulty in analyzing the energy impact of architectural and microarchitectural features without constructing detailed implementations and running slow simulations. This thesis first describes the design of a fast, accurate, and flexible circuit simulation tool which enables transition-sensitive studies of microprocessor energy consumption that would otherwise be impossible or impractical. With a simulation infrastructure in place, various optimizations are implemented that target the entire datapath and cache energy consumption. The individual energy optimizations are analyzed in detail, and the microprocessor design is characterized using various energy breakdowns and studies of the bit correlation between data values. This work shows that a few relatively simple energy-saving techniques can have a large impact in the implementation of an energy-efficient microprocessor. By fully characterizing the energy usage, this thesis establishes a coherent vision of microprocessor energy consumption, and serves as a basis and motivation for further energy optimizations.by Ronny Krashinsky.S.M

"La république de Dieu" : une utopie suédoise de 1789
No full textIn 1789 was published a brochure entitled « A Plan for a Free Community » outlining a project of colonisation in Africa; its was signed by four authors, of whom two Swedes were the more important: August Nordenskjôld and Carl Bernhard Wadstrom. The « Plan » devised a Utopia filled with the Swedenborgian philosophical questioning about the possibility of founding a new Jerusalem. Wadström was a technician and a manufacturer; Nordenskjöld, the main author, was a mineralogist and once more an alchimist. Through the study of their lives and their project, the whole intellectual background of the Swedish Enlightenment comes to life, and one can note how the thought of Swedenborg influenced it and how the influence and ties with London and with French physiocratic thought were involved in it. These men dreamed of eliminating the tyranny of money by building a society founded on love and work.En 1789 a été publiée sous le titre « Plan for a free Community » une brochure invitant à un projet de colonisation en Afrique signé de quatre auteurs, dont essentiellement les suédois August Nordenskjôld et Cari Bernhard Wadström. C'est en fait une utopie imprégnée des modèles de pensée sweden- borgiens, qui s'interroge sur les conditions de la fondation de la Nouvelle Jérusalem, Wadström est un technicien et fabricant, Nordenskjöld principal auteur, un minéralogiste et plus encore un alchimiste. A travers leur carrière, comme leur projet tout un milieu intellectuel des Lumières suédoises est évoqué, illus- tant ce que la pensée de Swedenborg a pu y représenter, les liens et les influences aussi, avec Londres surtout mais aussi avec la pensée physiocratique française. On rêve d'éliminer la tyrannie de l'argent en bâtissant une société fondée sur l'amour et le travail.Ambjörnsson Ronny, Heyun Jean. "La république de Dieu" : une utopie suédoise de 1789.

Vector-thread architecture and implementation
Full text linkThesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2007.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Includes bibliographical references (p. 181-186).This thesis proposes vector-thread architectures as a performance-efficient solution for all-purpose computing. The VT architectural paradigm unifies the vector and multithreaded compute models. VT provides the programmer with a control processor and a vector of virtual processors. The control processor can use vector-fetch commands to broadcast instructions to all the VPs or each VP can use thread-fetches to direct its own control flow. A seamless intermixing of the vector and threaded control mechanisms allows a VT architecture to flexibly and compactly encode application parallelism and locality. VT architectures can efficiently exploit a wide variety of loop-level parallelism, including non-vectorizable loops with cross-iteration dependencies or internal control flow. The Scale VT architecture is an instantiation of the vector-thread paradigm designed for low-power and high-performance embedded systems. Scale includes a scalar RISC control processor and a four-lane vector-thread unit that can execute 16 operations per cycle and supports up to 128 simultaneously active virtual processor threads. Scale provides unit-stride and strided-segment vector loads and stores, and it implements cache refill/access decoupling. The Scale memory system includes a four-port, non-blocking, 32-way set-associative, 32 KB cache. A prototype Scale VT processor was implemented in 180 nm technology using an ASIC-style design flow. The chip has 7.1 million transistors and a core area of 16.6 mm2, and it runs at 260 MHz while consuming 0.4-1.1 W. This thesis evaluates Scale using a diverse selection of embedded benchmarks, including example kernels for image processing, audio processing, text and data processing, cryptography, network processing, and wireless communication.(cont.) Larger applications also include a JPEG image encoder and an IEEE 802.11 la wireless transmitter. Scale achieves high performance on a range of different types of codes, generally executing 3-11 compute operations per cycle. Unlike other architectures which improve performance at the expense of increased energy consumption, Scale is generally even more energy efficient than a scalar RISC processor.by Ronny Meir Krashinsky.Ph.D
Evaluation Metrics for Continuous Human Activity Classification Using Distributed Radar Networks
No full textContinuous Human Activity Recognition (HAR) in arbitrary directions is investigated using 5 spatially distributed pulsed Ultra-Wideband (UWB) radars. Such activities performed in arbitrary and unconstrained trajectories render a more natural occurrence of Activities of Daily Living (ADL) to be recognized. An innovative signal level fusion method was applied on the Range-Time (RT) maps, and deep learning classification via Recurrent Neural Networks (RNN) with and without bidi-rectionality was used on the computed micro-Doppler (μD) spectrogram. To assess classification performances, novel evaluation metrics accounting for the continuous nature of the sequence of activities and for imbalances in the dataset are proposed and compared with existing metrics. It is shown that conventional accuracy evaluation is too coarse, and that the proposed metrics need to be considered for a more comprehensive evaluation.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Microwave Sensing, Signals & System
Phase-based Classification for Arm Gesture and Gross-Motor Activities using Histogram of Oriented Gradients
No full textMicro-Doppler spectrograms are a conventional data representation domain for movement recognition such as Human Activity Recognition (HAR) or gesture detection. However, they present the problem of time-frequency resolution trade-offs of Short-Time Fourier Transform (STFT), which may have limitations due to unambiguous Doppler frequency, and the STFT computation may be onerous in constrained embedded environments. We propose in this paper an alternative classification approach based on the radar phase information directly extracted from high-resolution Range Map (RM). This novel approach does not use the aforementioned micro-Doppler processing, and yet achieves equivalent or even superior classification results. This shows a potential advantage for low-latency, real-time applications, or computationally constrained scenarios. The proposed method exploits the Histogram of Oriented Gradients (HOG) algorithm as an effective feature extraction algorithm, specifically its capability to capture the unique shape and patterns present in the wrapped phase domains, such as their contour intensity and distributions. Validation results consistently above 92% demonstrate the effectiveness of this method on two independent datasets of arm gestures and gross-motor activities. These were classified with three algorithms, namely the Nearest Neighbor (NN), the linear Support Vector Machine (SVM), and the Gaussian SVM classifiers using the proposed phase information. Feature fusion of different data domains, e.g. the modulus of the RM fused with the RM phase information, is also investigated and shows classification improvement specifically for the robustness of activity performances, such as the aspect angle and the speed of performance.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Microwave Sensing, Signals & System
