Design of Advanced Digital Systems Based on High-Speed Optical Links

2012

Optical fiber links offer very important benefits as EMI immunity, low losses, high bandwidth, etc, so an increasing number of communication applications are being developed and deployed. At both sides of these optical links, the optical data signal has to be converted to (or from) the electronic domain. The processing of such a high speed optical signals is not straightforward in most cases, and special considerations need to be taken into account for a proper electronic design.

Polyester microplastic fibers affect soil physical properties and erosion as a function of soil type

2021

Microplastics are recognized as a factor of global change contaminating many environmental compartments. Agricultural soils are very likely to receive microplastic contamination and are of particular concern due to their role in food production. Microplastic fibers have already been shown to be able to affect soil properties, but their effect on different soil types is poorly understood. Moreover, limited information is available on how the presence of this pollutant can affect soil water erosion processes, which are extremely important issues in many environments. In the light of this, we performed two experiments (carried out on a microscale) to investigate how the presence of polyester m…

A Multilayered Plate Theory with Transverse Shear and Normal Warping Functions

2016

A multilayered plate theory which takes into account transverse shear and normal stretching is presented. The theory is based on a seven-unknowns kinematic field with five warping functions. Four warping functions are related to the transverse shear behaviour, the fifth is related to the normal stretching. The warping functions are issued from exact three-dimensional solutions. They are related to the variations of transverse shear and normal stresses computed at specific points for a simply supported bending problem. Reddy, Cho-Parmerter and (a modified version of) Beakou-Touratier theories have been retained for comparisons. Extended versions of these theories, able to manage the normal s…

Economists and Eugenics: Progressive Era Racism and its (Jewish) Discontents

2017

This chapter analyzes the contribution to the debates on labor and immigration of a group of Jewish academicians and reformers who, during the second half of the Progressive Era, explicitly took a stance against the racialist and eugenic rhetoric of the period. This group includes first-rank economists like Edwin R. A. Seligman, Jacob H. Hollander, and Emanuel A. Goldenweiser; influential field specialists such as Isaac A. Hourwich and Isaac M. Rubinow; and relatively less known figures like Max J. Kohler and Samuel K. Joseph. By focusing on the voices of these dissenters, this chapter enriches the emerging picture of Progressive Era eugenic and racial thought.

Côté mauvaises herbes, tir de barrage sur trois envahissantes

2006

National audience; Les plantes envahissantes sont évoquées à la conférence sur les zones non agricoles de l'AFPPà Avignon les 11 et 12octobre 2006. La situation à leur égard en France et en Europe est présentée, notamment les dispositions réglementaires et l'identité des 34 principales espèces. Deux communications traitent de l'ambroisie à feuille d'armoise Ambrosia artemisiifolia. Un point sur les méthodes de lutte mécanique, chimique, etc.) insiste sur l'intérêt de la prévention (enherbement, etc.)et de la concertation entre acteurs agricoles et non agricoles. Des essais de lutte chimique (glyphosate ou glufosinate-ammonium en 2004 et 2005, les montrent équivalents et intéressants en débu…

The effects of water absorption and salt fog exposure on agglomerated cork compressive response

2022

The replacement of synthetic foams with agglomerated cork in sandwich composites can meet the increasing environmental concerns. Its peculiar morphology and chemical composition lead to outstanding dimensional recovery that endorsed a broad investigation of its compressive behavior. The knowledge of neat material response is fundamental to obtain a reliable design dataset, but it is necessary to consider all the environmental factors (water, moisture and sunlight) that significantly modify material mechanical properties. In view of this, the present work investigates the effect of distilled and seawater absorption and salt fog exposure on the compressive behavior of two agglomerated corks w…

A Metaheuristic Bandwidth Allocation Scheme for FiWi Networks Using Ant Colony Optimization

2015

Optical-wireless access networks constitute a quite attractive solution to meet the ever-increasing bandwidth requirements of end-users, offering significant benefits such as ubiquitous coverage in the wireless domain and huge bandwidth in the optical domain. However, converging optical and wireless networking technologies, with Passive Optical Networks (PONs) and 4G wireless standards, such as the Worldwide Interoperability for Microwave Access (WiMAX) and the Long Term Evolution (LTE), entails major challenges that need to be addressed. In this context, designing an efficient and fair bandwidth distribution with Quality of Service (QoS) support is a difficult task due to the interdependen…

Translation, adaptation and psychometric validation of the preterm birth experience and satisfaction scale (P-BESS) into Spanish.

2018

Abstract Background Preterm labour and birth are two of the most important issues in perinatal care. The birth of a preterm baby is often a stressful and traumatic time for parents. Assessment of satisfaction with maternity services is crucial and questionnaires are the most common method as long as they are well-constructed. Only one, The Preterm Birth Experience and Satisfaction Scale (P-BESS), developed in United Kingdom, has been designed for this specific birth type. Objectives To translate, transculturally adapt and assess the psychometric properties of the P-BESS into Spanish. Design Cross-sectional study. Setting Maternity unit of a tertiary level hospital in Spain. Participants A t…

Factors That Contribute or Impede the Physical Health Recovery of Women Exposed to Intimate Partner Violence: A Longitudinal Study

2012

Abstract Background Several cross-sectional studies have demonstrated the negative impact that intimate partner violence (IPV) has on the physical health of women. However, longitudinal studies are needed to establish the time course of this effect. This study assessed the physical health course of female IPV victims and established the factors that enhance or impede their recovery. Methods Women ( n  = 91) who participated in a previous cross-sectional study (T-1) and were either victims of physical/psychological IPV ( n  = 33) or psychological IPV ( n  = 23) were evaluated 3 years later (T-2). A control group of women ( n  = 35) was included for comparison. Structured interviews provided …
