Histeria: historia da sexualidade feminina

Introducción: Etimológicamente el término Histeria proviene de la palabra griega Hysteron que significa Útero. De esto deducimos, la feminización de la enfermedad y la vinculación al ideal de mujer históricamente vigente. Objetivos: Dar a conocer la Histeria y el lazo que la une con la sexualidad femenina a lo largo de diferentes épocas históricas. Material y método: Revisión Bibliográfica Sistemática en Bases de datos. Resultados: Diferentes racionamientos tratan de esclarecer la etiología y sintomatología de la enfermedad. Resulta llamativo, por otro lado, el tratamiento clandestino que algunas mujeres histéricas reciben: los masajes pélvicos. Conclusiones: Análisis del legado de las mujeres que sufrieron la estigmatización de ser tachadas de histéricas desde una visión actual. Cómo vemos la Histeria hoy: significado y connotaciones.Introduction: Hysteria comes from hysteron, a Greek word that means Uterus. From there it follows the feminization of the disease and the link with the prototype of perfect woman at that time. Objective: Study the relationship between Hysteria and female sexuality through different historical periods. Materials and Methods: Literature Review in Databases. Results: Different studies try to explain the etiology and symptomatology of Hysteria. It calls our attention that some women were treated in a clandestinely way: pelvic massages. Conclusions: Analysis of the legacy of women who suffered from the stigmatization of being branded as hysterical women at present.

On interpolation of the measure of noncompactness

We revised the known results on interpolation of the measure of noncompactness and we announce a new approach to establishing the interpolation formula for the real method

On compactness results of Lions-Peetre type for bilinear operators

Let Ā = (A₀ , A₁) , B̄ = (B₀ , B₁) be Banach couples, let E be a Banach space and let T be a bilinear operator such that ||T(a, b)||ᴇ ≤ M[sub]j ||a||ᴀ[sub]j ||b||ʙ[sub]j for a ∈ A₀ ∩ A₁, b ∈ B₀ ∩ B₁, j = 0, 1. If T : A°[sub]j × B°[sub]j −→ E compactly for j = 0 or 1, we show that T may be uniquely extended to a compact bilinear operator from the complex interpolation spaces generated by Ā and B̄ to E. Furthermore, the corresponding result for the real method is given and we also study the case when E is replaced by a couple (E₀, E₁) of Banach function spaces on the same measure space

Multi-task Implementation for Image Reconstruction of an AER Communication

Address-Event-Representation (AER) is a communication protocol for transferring spikes between bio-inspired chips. Such systems may consist of a hierarchical structure with several chips that transmit spikes among them in real time, while performing some processing. There exist several AER tools to help in developing and testing AER based systems. These tools require the use of a computer to allow the processing of the event information, reaching very high bandwidth at the AER communication level. We propose to use an embedded platform based on multi-task operating system to allow both, the AER communication and the AER processing without a laptop or a computer. We have connected and programmed a Gumstix computer to process Address- Event information and measured the performance referred to the previous AER tools solutions. In this paper, we present and study the performance of a new philosophy of a frame-grabber AER tool based on a multi-task environment, composed by the Intel XScale processor governed by an embedded GNU/Linux system.Ministerio de Ciencia e Innovación TEC2006-11730-C03-0

3D-form metrology of arbitrary optical surfaces by absorption in fluids

We present an imaging technique for the 3D-form metrology of optical surfaces. It is based on the optical absorption in fluids situated between the surface and a reference. An improved setup with a bi-chromatic light source is fundamental to obtain reliable topographic maps. It is able to measure any surface finish (rough or polished), form and slope and independently of scale. We present results focused on flat and spherical optical surfaces, arrays of lenses and with different surface finish (rough-polished). We achieve form accuracies from several nanometers to sub-lambda for sag departures from tens to hundred of microns. Therefore, it seems suitable for the quality control in the production of precision aspheric, freeform lenses and other complex shapes on transparent substrates, independently of the surface finish

The application of regenerable sorbents for mercury capture in gas phase

Mercury is a well-known toxic element, and flue gas streams emitted from coal-fired utilities are one of the largest anthropogenic sources of this element. This study briefly reviews the proposed technologies for reducing mercury emissions from coal combustion, focusing on an emerging process which involves the use of regenerable sorbents and especially those loaded with noble metals. Among the mercury species formed during coal combustion, elemental mercury is the most difficult to remove from the flue gases due to its low reactivity and insolubility in water. The widespread interest in using regenerable sorbents with metals is due to their ability to retain elemental mercury. With this technology, not only can efficiencies of 100 % be reached in the retention of elemental mercury but also a way to avoid the generation of new wastes loaded with mercury. This study considers the main aspects that must be taken into account when developing effective regenerable sorbents for mercury capture, with special attention to sorbents containing noble metals. The characteristics of this process are compared with those of other processes in a more advanced state of development.The financial support for this work was provided by the projects CTQ2014-58110-R and GRUPIN14-031.

AER and dynamic systems co-simulation over Simulink with Xilinx System Generator

Address-Event Representation (AER) is a neuromorphic communication protocol for transferring information of spiking neurons implemented into VLSI chips. These neuro-inspired implementations have been used to design sensor chips (retina, cochleas), processing chips (convolutions, filters) and learning chips, what makes possible the development of complex, multilayer, multichip neuromorphic systems. In biology one of the last steps of the processing is to move a muscle, to apply the results of these complex neuromorphic processing to the real world. One interesting question is to be able to transform, or translate, the AER information into robot movements, like for example, moving a DC motor. This paper presents several ways to translate AER spikes into DC motor power, and to control a DC motor speed, based on Pulse Frequency Modulation. These methods have been simulated into Simulink with Xilinx System Generator, and tested into the AER-Robot platform.Junta de Andalucía P06-TIC-01417Ministerio de Educación y Ciencia TEC2006-11730-C03-0

Spike Processing on an Embedded Multi-task Computer: Image Reconstruction

There is an emerging philosophy, called Neuro-informatics, contained in the Artificial Intelligence field, that aims to emulate how living beings do tasks such as taking a decision based on the interpretation of an image by emulating spiking neurons into VLSI designs and, therefore, trying to re-create the human brain at its highest level. Address-Event-Representation (AER) is a communication protocol that has embedded part of the processing. It is intended to transfer spikes between bioinspired chips. An AER based system may consist of a hierarchical structure with several chips that transmit spikes among them in real-time, while performing some processing. There are several AER tools to help to develop and test AER based systems. These tools require the use of a computer to allow the higher level processing of the event information, reaching very high bandwidth at the AER communication level. We propose the use of an embedded platform based on a multi-task operating system to allow both, the AER communication and processing without the requirement of either a laptop or a computer. In this paper, we present and study the performance of a new philosophy of a frame-grabber AER tool based on a multi-task environment. This embedded platform is based on the Intel XScale processor which is governed by an embedded GNU/Linux system. We have connected and programmed it for processing Address-Event information from a spiking generator.Ministerio de Educación y Ciencia TEC2006-11730-C03-0

From Vision Sensor to Actuators, Spike Based Robot Control through Address-Event-Representation

One field of the neuroscience is the neuroinformatic whose aim is to develop auto-reconfigurable systems that mimic the human body and brain. In this paper we present a neuro-inspired spike based mobile robot. From commercial cheap vision sensors converted into spike information, through spike filtering for object recognition, to spike based motor control models. A two wheel mobile robot powered by DC motors can be autonomously controlled to follow a line drown in the floor. This spike system has been developed around the well-known Address-Event-Representation mechanism to communicate the different neuro-inspired layers of the system. RTC lab has developed all the components presented in this work, from the vision sensor, to the robot platform and the FPGA based platforms for AER processing.Ministerio de Ciencia e Innovación TEC2006-11730-C03-02Junta de Andalucía P06-TIC-0141
