A Telemetry, Tracking, and Command Antennas System for Small-Satellite Applications
2019
Circularly polarized (CP) antennas are used in space applications for telemetry tracking and command (TT&
Creating Office Spaces in the Mediterranean. The importance of well-being, health and performance of office users
2018
Recent research has studied the influence of office buildings indoor environment quality (IEQ) on employees’ well-being, health and performance. However, it seems that it has not been explicitly explored what are the appropriate environmental conditions to different work patterns that coexist in these spaces. This paper presents results of an empirical research, based on the synchronized measurements of different IEQ parameters (i.e., noise, lighting and temperature), and well-being, health and performance of 71 employees in twelve office spaces in the Valencian Community along three periods, considering winter and summer conditions. Findings of the first winter period data, suggest the exi…
On the use of composite indicators for mobile communications network management in smart sustainable cities
2020
Beyond 5G networks will be fundamental towards enabling sustainable mobile communication networks. One of the most challenging scenarios will be met in ultra-dense networks that are deployed in densely populated areas. In this particular case, mobile network operators should benefit from new assessment metrics and data science tools to ensure an effective management of their networks. In fact, incorporating architectures allowing a cognitive network management framework could simplify processes and enhance the network&rsquo
Smart and valued? ICT urban (transport) solutions in the city official communication
2022
To optimize the everyday functioning of a city, urban authorities can implement smart city tools and solutions. Mobility is a typical field associated with the concept of a smart city. It is interesting to take a closer look at the solutions applied through the information accessible on the official websites, while exploring, at the same time, the possibilities offered by new research tools. The main objective of this work is to establish the significance of the information and communication technologies (ICT) in the process of creating smart mobility in a smart city, based on the texts posted on official websites. Using the natural language processing (NLP) methods and tools offered by the…
La 5th IABR di Rotterdam: How do we go about making city?
2012
The projects shown during the 5th IABR (International Architecture Biennale Rotterdam) "Making City", hold in Rotterdam in 2012, have treated the topic linked to the development of some specific contests, through the individuation of many factors which influence the urban planning, as global tendencies, cooperation and smart connections: these are necessary strategies to define a Smart City. They are connected not only to the infrastructures and to digital connections, but also to the business, understanding of technology, users for urban planning and control of features from which depends the success of future cities. From the integration’s ability of Architecture, urban planning and lands…
Characterization of IP-Based Communication for Smart Grid Using Software-Defined Networking
2018
The smart grid (SG) approach is based on a strong interaction between the network communication infrastructure and the power grid. Usually the management of the infrastructure is done by the distribution system operators (DSOs) that are worried about the increasing managing complexity due to the presence of increasing number of distributed energy resources and electrical vehicles. The use of software-defined networking (SDN) may simplify the network configuration and management for DSO, as highlighted from previous research works. The objective of this paper is to introduce and characterize an internet protocol (IP)-based communication architecture with specialized SDN bridges operating als…
PQ and Harmonic Assessment Issues on Low-Cost Smart Metering Platforms: A Case Study
2020
This paper presents a feasibility study on how to implement power quality (PQ) metrics in a low-cost smart metering platform. The study is aimed at verifying the possibility of implementing PQ monitoring in distribution networks without replacing existing smart metering devices or adding new modules for PQ measurements, thus zeroing the installation costs. To this aim, an electronic board, currently used for remote energy metering, was chosen as a case study, specifically the STCOMET platform. Starting from the specifications of this device, the possibility of implementing power quality metrics is investigated in order to verify if compliance with standard requirements for PQ instruments ca…
INTRODUCTION TO WEARABLE HEALTHCARE TECHNOLOGY
2017
Teknologian nopea kehitys on mahdollistanut ennennäkemättömän pienten tietokoneiden valmistuksen. Puettavat teknologiat käyttävät hyväkseen näitä pieniä puettavia laitteita, joilla on tarkoitus parantaa elämänlaatua. Puettavien teknologialaitteiden määrän kasvun on odotettu saavuttavan miljardin laitteen rajan vuoden 2022 tienoilla. Koska terveydenhuolto hyötyy teknologian kehityksestä, se on oiva kohde puettavan teknologian hyödylliseen käyttöön. Tämän tutkielman tarkoituksena on luoda yleislaatuinen selvitys puettavista teknologioista, niiden antamista mahdollisuuksista ja riskitekijöistä terveydenhuollon alalla. Aiemmat tutkimukset asiasta ovat keskittyneet lähinnä puettavan teknologian …
Physical Weaponization of a Smartphone by a Third Party
2022
In the literature and media, the treatment of the dangers and exposures posed by smartphones has generally focused on information security or privacy concerns. There have also been reports of fires, explosions, electric shocks, or loss of phone functionality due to faulty design or manufacture. This article provides an overview of acute physical and physiological dangers of smartphones that could be induced or triggered by a third party. It proposes a categorical discussion framework to describe and define the dangers in terms of attack vectors, effects on the smartphone, harms, and potential culprits/instigators. Counterfeit smartphones are themselves a significant potential threat in this…
Adsorption of anionic dyes onto natural, thermally and chemically modified smectite clays
2014
Abstract The aim of this study was to determine the adsorption capacity of the smectite clays (from the overburden of the lignite deposit in Belchatow) for two anionic dyes, i.e. Reactive Blue 81 (RB-81) and Direct Blue 74 (DB-74). Additionally, the influence of the thermal and chemical (acid and alkali) clay modifications on the amount of bonded dyes was investigated. The adsorption capacity of the clay (natural and modified) was different for studied dyes and depended on the initial concentration and modification type. All the modified clays adsorbed the dyes at pH>pHPZC as the negatively charged surfaces of their particles (in accordance with the formula: AOH ↔ AO- + H+) prevented the…
