Progress in analysis of residual antibacterials in food
2007
Abstract Residual antibacterials in food constitute a risk to human health. Although epidemiological data on the real magnitude of their adverse effects are very scarce, they indicate that food could be an important avenue for evolution and dissemination of antibiotic-resistant bacteria. Analysis of these residues plays a key role in ensuring food safety, to the point that the European Union has not only established maximum residue limits but also requirements concerning the performance of analytical methods and the interpretation of the results. These specifications have had a great influence on protocols and techniques applied. In this review, we discuss the progress of rapid screening me…
Smart Micro-Grid Performance using Renewable Energy
2020
The aim of this research is to determine the performance of PV panels, wind turbines, battery storage and power imported from the grid to the system which will ensure a reliable energy supply, as well as the technical feasibility of a smart microgrid system. Indonesia’s renewable energy potential for electricity reaches 443 GW, where solar energy is the largest potential, namely 4.8 KWh m–2 or equivalent to 112 000 GWp, but only 10 MWp has been utilized. The most basic problem in this system, namely, the uncertainty of wind energy and solar energy, one of the most vital factors in the optimal size of a renewable energy-based smart microgrid system is the reliability of the system being buil…
Etude analytique en régime dynamique des performances thermiques des parois en blocs de terre stabilisée
2023
L’objectif visé à travers cette étude est de parvenir à dimensionner de manière optimale les épaisseurs des murs en blocs de terre stabilisée (BTS), pour obtenir un confort thermique satisfaisant à l’intérieur des constructions avec ce matériau. Pour ce faire, une méthode analytique des admittances basée sur le complexe de Fourier est utilisée. L’analyse des résultats a mis en exergue les principaux facteurs influents sur le dimensionnement idoine pour parvenir à assurer un confort thermique satisfaisant à l’intérieur de ces constructions en terre. Parmi ces facteurs, on relève les caractéristiques thermo-physiques intrinsèques des matériaux utilisés et d’autres paramètres tels que le facte…
Risposta ornamentale di accessioni di peperoncino coltivati in vaso
2008
Gran parte delle varietà di peperoncino, coltivate a scopo alimentare, è considerata interessante anche ai fini ornamentali. Ciò è attribuibile principalmente al frutto che rende questa pianta idonea alla coltivazione in vaso e per la realizzazione di aiuole e bordure. Il Consorzio di ricerca Co.Ri.S.S.I.A. di Palermo ha avviato una ricerca allo scopo di valorizzare il peperoncino come specie ornamentale da vaso. Sono state confrontate 34 varietà di peperoncino coltivate in quattro differenti tipologie di vaso, rilevando i principali parametri morfologici e estetici. La specie ha manifestato una buona adattabilità alla coltivazione in vaso, avvalorando, nel contempo, il suo impiego anche pe…

Communication-Efficient Federated Learning in Channel Constrained Internet of Things
2022
Federated learning (FL) is able to utilize the computing capability and maintain the privacy of the end devices by collecting and aggregating the locally trained learning model parameters while keeping the local personal data. As the most widely-used FL framework,Jederated averaging (FedAvg) suffers an expensive communication cost especially when there are large amounts of devices involving the FL process. Moreover, when considering asynchronous FL, the slowest device becomes the bottleneck for the cask effect and determines the overall latency. In this work, we propose a communication-efficient federated learning framework with partial model aggregation (CE-FedPA) algorithm to utilize comp…

Electron and photon performance measurements with the ATLAS detector using the 2015-2017 LHC proton-proton collision data
2019
This paper describes the reconstruction of electrons and photons with the ATLAS detector, employed for measurements and searches exploiting the complete LHC Run 2 dataset. An improved energy clustering algorithm is introduced, and its implications for the measurement and identification of prompt electrons and photons are discussed in detail. Corrections and calibrations that affect performance, including energy calibration, identification and isolation efficiencies, and the measurement of the charge of reconstructed electron candidates are determined using up to 81 fb−1 of proton-proton collision data collected at √s=13 TeV between 2015 and 2017.
Technical and economic aspects of photovoltaic conversion of southern Poland
2014
W artykule przedstawiono wyniki 13-letniej analizy testowania sprawności oraz uzysku energii i ładunku elektrycznego typowych modułów fotowoltaicznych wykonanych z różnych absorberów, zainstalowanych na południowej ścianie budynku Uniwersytetu Opolskiego przy ulicy kard. B. Kominka. Zarejestrowane w tym okresie (2001-2013) wartości kumulacji energii i ładunku testowanych modułów przedstawiono zarówno w odniesieniu do 1 Wp ich mocy nominalnej, jak i do 1 m2 powierzchni modułów PV. Przedstawiono ich roczne i miesięczne rozkłady ze szczególnym uwzględnieniem sezonowości zmian ich parametrów oraz zjawiska starzenia i degradacji struktury modułów PV.

The Investment Performance of U.S. Islamic Mutual Funds
2020
Islamic investment funds have become increasingly important because of high demand from many investors, including those outside the Muslim investment community. This article compares the performance and risk sensitivity of Islamic mutual funds in the United States with that of their conventional peers. This article also analyzes the performance of Islamic funds, and compares this performance with that of socially responsible investment (SRI) mutual funds. Capital Asset Pricing Model (CAPM)-based methodology was used for the analysis. The results suggest that over the entire study period (1987&ndash
