Dziewiętnastowieczne górnośląskie protokoły sądu rozjemczego jako podstawa badań językowych
2019
Artykuł dowodzi, że w warunkach obcej państwowości ukształtował się w XIX stuleciu na Śląsku polski protokół sądowy jako gatunek tekstu. Oparty był na wzorach niemieckich, wymaganych przez oficjalne czynniki administracyjne. Zawierał konstytutywne wyznaczniki gatunkowe protokołu. Świadczą o tym liczne protokoły polskie zapisane w księgach protokolarnych sądów rozjemczych powiatu strzeleckiego, przechowywane w Archiwum Państwowym w Opolu. Istnienie i funkcjonowanie tego gatunku w określonej sytuacji historycznej Śląska, na przestrzeni siedmiu dziesięcioleci, w warunkach dominacji niemczyzny i przy stałe nasilających się naciskach germanizacyjnych świadczy o nieco szerszym zakresie użytkowani…
Opolska różnorodność. Praktyczny wymiar wielokulturowości regionu na przykładzie województwa opolskiego
2020
Th e Opolskie Voivodeship is the smallest Polish region in terms of territory and population. Its national diversity, which is also mentioned in regional development documents, is defi ned as one of its greatest assets. In fact, the Opolskie Voivodeship is the home of the largest and best organized national minority in Poland – the German minority. Th e socio-political and cultural activity of the community is a popular subject of scientifi c analysis. On the basis of the activity and participation of this group in Polish public life, both nationwide and regionally, it is possible to study how Polish society (also at the regional level) and state power structures implement the democratic pr…
Univariate and multivariate properties of wind velocity time series
2009
We analyze the time series of hourly average wind speeds measured at 29 different stations located in Sicily, a region with a complex morphology. The investigation, performed from the univariate as well as the multivariate point of view, evidences that the statistical properties of wind at the single sites have features that are not reproduced by standard models and, thus, require specific modeling. Moreover, the synchronous evolution of wind velocity presents a cluster structure, obtained with different algorithms, that persists in the standard deviation too.
Learn to Cache: Machine Learning for Network Edge Caching in the Big Data Era
2018
The unprecedented growth of wireless data traffic not only challenges the design and evolution of the wireless network architecture, but also brings about profound opportunities to drive and improve future networks. Meanwhile, the evolution of communications and computing technologies can make the network edge, such as BSs or UEs, become intelligent and rich in terms of computing and communications capabilities, which intuitively enables big data analytics at the network edge. In this article, we propose to explore big data analytics to advance edge caching capability, which is considered as a promising approach to improve network efficiency and alleviate the high demand for the radio resou…
A Double Auction Mechanism for Virtual Resource Allocation in SDN-based Cellular Network
2016
The explosively growing demands for mobile traffic service bring both challenges and opportunities to wireless net- works, among which, wireless network virtualization is proposed as the main evolution towards 5G. In this paper, we first propose a Software Defined Network (SDN) based wireless virtualization architecture for enabling multi-flow transmission in order to save capital expenses (CapEx) and operation expenses (OpEx) significantly with multiple Infrastructures Providers (InPs) and multiple Mobile Virtual Network Operators (MVNOs). We for- mulate the virtual resource allocation problem with diverse QoS requirements as a social welfare maximization problem with transaction cost. Due…
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…
Underwater Multirobot Cooperative Intervention MAC Protocol
2020
This work introduces a Medium Access Control (MAC) protocol designed to allow a group of underwater robots that share a wireless communication channel to effectively communicate with each other. The goal of the Underwater Multirobot Cooperative Intervention MAC (UMCI-MAC) protocol presented in this work is to minimize the end to end delay and the jitter. The access to the medium in UMCI-MAC follows a Time Division Multiple Access (TDMA) strategy which is arbitrated by a master, which also has the capability to prioritize the transmission of some nodes over the rest of the network. Two experiments have been carried out with a team of four Autonomous Underwater Vehicles (AUV) in order to comp…
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…
Futile Therapy versus Worthy Dying: Anthropological and Ethical Arguments
2020
Nowadays, issues related to the final stages of life stand more and more at the centre of problems relating to life and health, which result, for example, from the demographic situation in highly developed societies. In the last decades of the twentieth century, an explosion of therapeutic possibilities in the field of technical medicine has caused such questions to be voiced more and more frequently: Should humans try to live as long as possible, or should they live as long as they can with dignity and then die with dignity? Despite the seemingly obvious answer, there is still considerable medical and social resistance to the policy of discontinuing futile therapy. There are probably many …
Opiniones y experiencias en el desempeño de la dirección escolar de las mujeres directoras en Andalucía
2008
Este trabajo persigue identificar las opiniones y experiencias ante la dirección escolar de las directoras de centros públicos de Educación Infantil y Primaria en Andalucía. Se realizó un estudio tipo encuesta con una muestra de 206 directoras seleccionada mediante un muestreo polietápico, utilizando el cuestionario para la recogida de información. Los resultados muestran que las directoras tienen mediana edad, una dilatada experiencia profesional y, en su mayoría, están relativamente libres de cargas familiares. Accedieron al cargo por razones altruistas y personales, y señalan la falta de apoyo de la Administración como su principal problema. Conciben su función como una labor de equipo e…
