Book Discussion : PJ Powers
No full textThe UJ Campus Health Services and the Student Affairs Division in partnership with the UJ Library invite you to meet PJ Powers (Thandeka) the co-author of the book HERE I AM About the book: Here I Am, written with Marianne Thamm, is an intimate and hilarious account of the life and times of one of this country’s most recognisable and enduring performers. From the dizzying heights of international stardom to the dark depths of her struggle with alcohol, this is a must-read to explore the heady mix of politics and music of the time. More than just a story about the personal journey of one of South Africa’s most beloved music icons, this extraordinary memoir of PJ Powers – or Thandeka, as she was affectionately renamed by Soweto crowds – is set against the turbulent backdrop of South Africa’s recent political history. It features a gallery of political leaders and international celebrities, including the likes of Nelson Mandela, Graça Machel, Chris Hani, Joaquim Chissano, Queen Elizabeth II, Brenda Fassie, Sharon Stone and Robert De Niro. Facilitator: Prof Alban Burke, Director – PsyCad, University of Johannesburg PJ Powers will also perform a few songs on the day. Date: 27 August 2015 Time: 16:30 for 17:00 Venue: Auditorium (6th Floor), APK Library, University of Johannesburg (corner Kingsway and University Road, Auckland Park) RSVP: By Wednesday, 26 August 2015 to Theodorah Modise on [email protected] / 011 559 226

How Did All These Barbarians Get Here? The (Im)Permeable Gates of the Caucasus in Late Antiquity in Jerome’s Letter 77 and Claudian’s Against Rufinus
No full textThe main pass through the central Caucasus Mountains, the present-day Dariali Gorge, had various names in ancient Greco-Latin sources: the Gates of the Caucasus, the Caspian Gates, Gates of Alexander, Sarmatian Gates. These Gates represented the frontier between the known and unknown worlds and were understood as an impermeable barrier to the barbarian groups from the Eurasian Steppe. This paper demonstrates the intersection between rhetoric and historicity and explains how these tropes about the Gates of the Caucasus were recycled in Late Antiquity and given new meaning in the context of the Hunnic invasion of the Near East in A.D. 395-398. This paper argues that Jerome’s Letter 77 and Claudian’s Against Rufinus used the perception of this gate as an impermeable barrier to further their literary agendas. Jerome used this perception to highlight the gravity of the Hunnic incursion to justify why Fabiola, a close friend and a devout Christian, had left Jerome’s side and returned to Rome before completing her pilgrimage. The literary associations of the Gates of the Caucasus also supported Jerome’s interpretation of the Hunnic incursion as divine punishment and an invitation for repentance. Claudian employed this same perception for a very different purpose: to slander a political opponent
An energy efficient time-mode digit classification neural network implementation
No full textThis paper presents the design of an ultra-low energy neural network that uses time-mode signal processing). Handwritten digit classification using a single-layer artificial neural network (ANN) with a Softmin-based activation function is described as an implementation example. To realize time-mode operation, the presented design makes use of monostable multivibrator-based multiplying analogue-to-time converters, fixed-width pulse generators and basic digital gates. The time-mode digit classification ANN was designed in a standard CMOS 0.18 μm IC process and operates from a supply voltage of 0.6 V. The system operates on the MNIST database of handwritten digits with quantized neuron weights and has a classification accuracy of 88%, which is typical for single-layer ANNs, while dissipating 65.74 pJ per classification with a speed of 2.37 k classifications per second. This article is part of the theme issue 'Harmonizing energy-autonomous computing and intelligence'.Accepted Author ManuscriptBio-Electronic
Bit-serial multipliers for exponentiation and division in GF(2(m)) using irreducible AOP
No full textFinite field GF(2(m)) is important to many practical application of modern communication. Exponentiation, division, and inversion are time-consuming operations that slow down the arithmetic over finite field GF(2(m)). They can be implemented by the iterative application of multiplication and squaring. However, it is efficient to use AB(2) operations rather than multiplication and squaring for computing exponentiation, division, and inversion. In ICCSA 2003 Lee et al. proposed a bit-serial AB(2) multiplier, which is more efficient than previous works. We propose new AB(2) multipliers using irreducible AOP (All One Polynomial) in this paper. Our multipliers require a smaller numbers of gates and have less latency than Lee et al.'s multiplier.X111sciescopu
An Energy-Efficient Multi-Sensor Compressed Sensing System Employing Time-Mode Signal Processing Techniques
No full textThis paper presents the design of an ultra-low energy, rakeness-based compressed sensing (CS) system that utilizes time-mode (TM) signal processing (TMSP). To realize TM CS operation, the presented implementation makes use of monostable multivibrator based analog-to-time converters, fixed-width pulse generators, basic digital gates and an asynchronous time-to-digital converter. The TM CS system was designed in a standard 0.18 µm IC process and operates from a supply voltage of 0.6V. The system is designed to accommodate data from 128 individual sensors and outputs 9-bit digital words with an average reconstruction SNR of 35.31 dB, a compression ratio of 3.2, with an energy dissipation per channel per measurement vector of 0.621 pJ at a rate of 2.23 k measurement vectors per second.Accepted author manuscriptBio-Electronic
