Energy Efficient Optimization for Wireless Virtualized Small Cell Networks With Large-Scale Multiple Antenna

2017

Wireless network virtualization is envisioned as a promising framework to provide efficient and customized services for next-generation wireless networks. In wireless virtualized networks (WVNs), limited radio resources are shared among different services providers for providing services to different users with heterogeneous demands. In this paper, we propose a resource allocation scheme for an orthogonal frequency division multiplexing-based WVN, where one small cell base station equipped with a large number of antennas serves the users with different service requirements. In particular, with the objective to obtain the energy efficiency in the uplink, a joint power, subcarrier, and antenn…

Resource Allocation and Computation Offloading for Wireless Powered Mobile Edge Computing

2022

In this paper, we investigate a resource allocation and computation offloading problem in a heterogeneous mobile edge computing (MEC) system. In the considered system, a wireless power transfer (WPT) base station (BS) with an MEC sever is able to deliver wireless energy to the mobile devices (MDs), and the MDs can utilize the harvested energy for local computing or task offloading to the WPT BS or a Macro BS (MBS) with a stronger computing server. In particular, we consider that the WPT BS can utilize full- or half-duplex wireless energy transmission mode to empower the MDs. The aim of this work focuses on optimizing the offloading decision, full/half-duplex energy harvesting mode and energ…

Exceptional women: Female merchants and working women in Italy in the early modern period

2018

The chapter examines the juridical construction of working woman in Italian cities during the medieval to modern period. In fact, the world of work and production had been generally thought by medieval and early modern jurists to be a sphere best left to self-regulation by the interested parties, an autonomous field, if not quite extraneous to the grand systems of Roman and canon law. But many regulatory and legal sources demonstrate the relevance of merchant and working women in the economic system. This sources concern three items, regarding female work and family roles: female membership and activities in the Italian guilds; women’s property and capability to act; the relationship betwee…

TIIVISTELMÄ Laaksonen, J. & O’Leary, S. 2017. Liikunnan- ja terveystiedonopettajat 2010 –luvulla. Työkykyyn vaikuttavat tekijät opettajien kokemina sekä vuosina 2012–2017 valmistuneiden opettajien kokemuk-sia työelämään siirtymisestä ja koulutuksista saaduista valmiuksista. Liikuntatieteellinen tiedekunta, Jyväskylän yliopisto, liikuntapedagogiikan pro gradu –tutkielma, 92 s, ja 11 liitettä. Tämän tutkimuksen tarkoituksena oli selvittää millaisiksi vuosina 2012¬–2017 valmistuneet liikunnan- ja terveystiedonopettajat kokevat koulutuksestaan saamansa valmiudet ja miten ne vastaavat työssä tarvittuja taitoja sekä miten odotukset työstä olivat kohdanneet todellisuutta siirryttäessä työelämään. …

Is the path to woman’s work satisfaction different than that of a man? Core self-evaluations and dominat

2015

The present paper analyses and validates a path model of the relation between male and female work satisfaction (dependent variable) and various psychological and economic variables (like wages, work certainty, work stress, core self-valuations and personal happies approach: hedonia or eudaemonia). The data analyzed comes from two author's projects, evaluating the sources of worker happiness: N = 1021 (Walczak, 2014) and N = 1105 (2015). The results indicate an partial mediation relation of gender on the perceived job satisfaction.

Efecto antibiótico sobre la dinámica de formación de biofilm endodóntico

2020

Es de vital importancia conocer la etiología y patogénesis de una enfermedad para desarrollar las formas más efectivas de prevención y tratamiento. Por ello, conocer y comprender la microbiología endodóntica, específicamente la biología de las biopelículas, que se forman en el interior de los conductos radiculares, es esencial para comprender el potencial patogénico de la microbiota y el desarrollo de tratamientos efectivos y eficientes. Las interacciones entre microorganismos presentes en un biofilm dotan a la comunidad de propiedades y funciones que no pueden observarse en cada componente de forma individual. Por este motivo, puede observarse un aumento de la virulencia, mayor resistencia…

Online ^{222}Rn removal by cryogenic distillation in the XENON100 experiment

2017

International audience; We describe the purification of xenon from traces of the radioactive noble gas radon using a cryogenic distillation column. The distillation column was integrated into the gas purification loop of the XENON100 detector for online radon removal. This enabled us to significantly reduce the constant$^{222}$ Rn background originating from radon emanation. After inserting an auxiliary$^{222}$ Rn emanation source in the gas loop, we determined a radon reduction factor of $R\,>\,27$ (95% C.L.) for the distillation column by monitoring the$^{222}$ Rn activity concentration inside the XENON100 detector.
