La perspectiva sistèmica de la violència

Esta ponencia trata de reflexionar sobre la condición humana del maltrato -por lo tanto, también del amor- y sobre la condición humana del poder. Partiendo de una visión del maltrato como fenómeno humano, el analisis se centra en el maltrato parental-filial. Se exponen brevemente las pautas relacionales disfuncionales del maltrato, las pautas sociales de elaboración del poder y las pautas del maltrato físico y se intenta relacionar todas ellas.This lecture aims at reflecting on the human condition of ill-treatment, and thus of love, and on the human condition of power. From a vision of ill-treatment as a human phenomenon, we focus on parent-child ill-treatment. The dysfunctional relational patterns of ill-treatment, the social patterns of power elaboration, and the patterns of physical abuse are briefly explained and related.Cet exposé vise a faire réfléchir sur la condition humaine du mauvais traitement et par conséquent de l'amour et sur la condition humaine du pouvoir. En partant d'une vision du mauvais traitement en tant que phénomene humain, l'accent est mis sur le mauvais traitement parental-filial. Nous exposons brihement les modeles relationnels dysfonctionnels du mauvais traitement, les modeles sociaux d'élaboration du pouvoir et les modeles du mauvais traitement physique. Nous tentons par ailleurs de les mettre en relation

Strategic risk management in water utilities: development of a holistic approach linking risks and futures

Risk management plays a key role in water utilities. Although tools are well established at operational and tactical levels of management, existing methods at strategic level lack a holistic treatment and a long-term perspective. In fact, risks are analysed per se, despite being interconnected; and long-term scenarios are commonly used for strategic planning, rather than for risk management, most of the time being related to one single issue (for example: climate change). In order to overcome the limitations identified in the existing methodologies, a novel approach for water utilities to manage risk at strategic level was developed and tested in EPAL - the largest and oldest water utility in Portugal. It consists of (i) setting a baseline risks comparison founded on a systemic model developed ‗bottom-up‘ through the business; (ii) the construction of future scenarios and an observation of how baseline risks may change with time. Major contributions of this research are the linkage between operational and strategic risks, capturing the interdependencies between strategic risks; the ability to look at long term risk, allowing the visualizing of the way strategic risks may change under a possible future scenario; and the novel coupling of risks and futures research. For the water sector, this approach constitutes a useful tool for strategic planning, which may be presented to the Board of Directors in a simple and intuitive way, despite the solid foundations of the underlying analysis. It also builds on in-house expertise, promoting the dissemination and pervasiveness of risk management within the companies and, on the other hand, allowing unveiling of existing knowledge, making it explicit and more useful for the organization

An Event-Driven Multi-Kernel Convolution Processor Module for Event-Driven Vision Sensors

Event-Driven vision sensing is a new way of sensing visual reality in a frame-free manner. This is, the vision sensor (camera) is not capturing a sequence of still frames, as in conventional video and computer vision systems. In Event-Driven sensors each pixel autonomously and asynchronously decides when to send its address out. This way, the sensor output is a continuous stream of address events representing reality dynamically continuously and without constraining to frames. In this paper we present an Event-Driven Convolution Module for computing 2D convolutions on such event streams. The Convolution Module has been designed to assemble many of them for building modular and hierarchical Convolutional Neural Networks for robust shape and pose invariant object recognition. The Convolution Module has multi-kernel capability. This is, it will select the convolution kernel depending on the origin of the event. A proof-of-concept test prototype has been fabricated in a 0.35 m CMOS process and extensive experimental results are provided. The Convolution Processor has also been combined with an Event-Driven Dynamic Vision Sensor (DVS) for high-speed recognition examples. The chip can discriminate propellers rotating at 2 k revolutions per second, detect symbols on a 52 card deck when browsing all cards in 410 ms, or detect and follow the center of a phosphor oscilloscope trace rotating at 5 KHz.Unión Europea 216777 (NABAB)Ministerio de Ciencia e Innovación TEC2009-10639-C04-0

CMOS OTA-C high-frequency sinusoidal oscillators

Several topology families are given to implement practical CMOS sinusoidal oscillators by using operational transconductance amplifier-capacitor (OTA-C) techniques. Design techniques are proposed taking into account the CMOS OTA's dominant nonidealities. Building blocks are presented for amplitude control, both by automatic gain control (AGC) schemes and by limitation schemes. Experimental results from 3- and 2- mu m CMOS (MOSIS) prototypes that exhibit oscillation frequencies of up to 69 MHz are obtained. The amplitudes can be adjusted between 1 V peak to peak and 100 mV peak to peak. Total harmonic distortions from 2.8% down to 0.2% have been measured experimentally.Comisión Interministerial de Ciencia y Tecnología ME87-000
