Usability in ERP (Single and Multiple Document Interface) Application Environments

2014

The usability of complex information systems, like enterprise resource planning (ERP), is the next frontier, as the trend becomes more and more adopted in the industrial working environment. In complex information systems, the traditional usability criteria of learnability, effectiveness and efficiency have never lost their importance, even though the focus of research appears to have shifted for the consumer product. This study based on 110 responses attempt to highlight the usability issues in ERP single document interface (SDI) and multiple document interface (MDI) application environments. It also investigates the effect of negative user experience, such as ‘confusion’, on learnability,…

Rendita catastale e “rendita solare” degli impianti di produzione elettrica a fonti rinnovabili: perequazione fiscale energetico-immobiliare

2014

Fra i temi affrontati dalla legge 11 marzo 2011, n. 23, recante delega al governo per un sistema fiscale più equo, spiccano le questioni fondamentali della riforma catastale e della fiscalità energetico-ambientale, di cui si tratta nel presente studio. La nuova riforma del catasto dei fabbricati aspira a realizzare un sistema fiscale più perequato at-traverso la rimozione della disparità fra redditi (e valori) catastali e redditi (e valori) osservabili nei mercati immobiliari. Il tema catastale è rilevante per i molteplici effetti fiscali che ne derivano, e il divario esistente fra i valori di mercato e quelli catastali, hanno suscitato un grande interesse degli studiosi di estimo, stimolan…

Bearing fault detection based on time-frequency representations of vibration signals

2015

To prevent failures of a rolling bearing in the gearbox drive system, acceleration sensors are used to detect fault-related signals of the bearing. It is a big challenge to observe and identify signals caused by bearing defects in the time domain or the frequency spectrum by a conventional Fourier analysis. The time-frequency representation of the fault-related signals implemented by the windowed Fourier transform is studied in this work. It is shown that the fault characteristic frequencies can be clearly identified in the time-frequency spectrum if a fault occurs in the bearing of the gearbox at different speeds. Otherwise, the shaft frequency and its multiples are the main harmonics in t…

Fast tracking of wind speed with a differential absorption LiDAR system: First results of an experimental campaign at Stromboli volcano

2017

Carbon dioxide ( CO 2 ) is considered a precursor gas of volcanic eruptions by volcanologists. Monitoring the anomalous release of this parameter, we can retrieve useful information for the mitigation of volcanic hazards, such as for air traffic security. From a dataset collected during the Stromboli volcano field campaign, an assessment of the wind speed, in both horizontal and vertical paths, performing a fast tracking of this parameter was retrieved. This was determined with a newly designed shot-per-shot differential absorption LiDAR system operated in the near-infrared spectral region due to the simultaneous reconstruction of CO 2 concentrations and wind speeds, using the same sample o…

Europe 2020: analisi multidimensionale a livello macro e micro per il confronto e il monitoraggio nel settore delle rinnovabili

Obiettivo generale del presente lavoro è proporre analisi statistiche di tipo multidimensionale finalizzate a valutare e monitorare gli effetti delle politiche Europee nel settore delle Fonti di Energia Rinnovabile (FER), con un focus specifico al monitoraggio della Europe2020 a livello regionale. La prima parte del lavoro presenta un panoramica storica dei principali atti legislativi con i quali è stata avviata concretamente la Politica Energetica sulle rinnovabili a livello Europeo. Alla luce delle informazioni così raccolte, la seconda parte della tesi ha avuto ad oggetto l’analisi dell’effetto, misurato in termini di Mega Watt installati, dei regimi di sostegno implementati da 11 Stati …

Ensemble deep clustering analysis for time window determination of event-related potentials

2023

Objective Cluster analysis of spatio-temporal event-related potential (ERP) data is a promising tool for exploring the measurement time window of ERPs. However, even after preprocessing, the remaining noise can result in uncertain cluster maps followed by unreliable time windows while clustering via conventional clustering methods. Methods We designed an ensemble deep clustering pipeline to determine a reliable time window for the ERP of interest from temporal concatenated grand average ERP data. The proposed pipeline includes semi-supervised deep clustering methods initialized by consensus clustering and unsupervised deep clustering methods with end-to-end architectures. Ensemble clusterin…

Pragmatic and Informative “Wholes”: the Evolutionary Roots of the Human Language

2011

The study of the origins of language has been the interest of several ungrounded debates which have often affected its scientific plausibility. In this paper, aiming at an internally consistent interdisciplinary approach, I will adopt Botha´s “Windows Approach" (2006) in order to justify the following two assumptions concerning the evolutionary roots of human language: a) despite the uniqueness of human language in sharing and conveying utterances with an open-ended structure, some isolated components of our linguistic competence are somehow shared with non-human primates, grounding a line of evolutionary continuity; b) the evolutionary thesis which sustains that the very first “linguistic”…

Hybridizing large neighborhood search and exact methods for generalized vehicle routing problems with time windows

2021

International audience; Delivery options are at the heart of the generalized vehicle routing problem with time windows (GVRPTW) allowing that customer requests are shipped to alternative delivery locations which can also have different time windows. Recently, the vehicle routing problem with delivery options was introduced into the scientific literature. It extends the GVRPTW by capacities of shared locations and by specifying service-level constraints defined by the customers' preferences for delivery options. The vehicle routing problem with delivery options also generalizes the vehicle routing problem with home roaming delivery locations and the vehicle routing problem with multiple time…

Sustainable vehicle routing based on firefly algorithm and TOPSIS methodology

2019

Abstract In a sustainable management of logistics, transportation plays a crucial role. Traditionally, the main purpose was to solve the Vehicle Routing Problem minimizing the cost associated with the travelled distances. Nowadays, the economic profit cannot be the only driver for achieving sustainability and environmental issues have to be also considered. In this paper, to satisfy the intricate limits involved in real vehicle routing problem, the study has been structured considering different types of vehicles in terms of maximum capacity, velocity and emissions, asymmetric paths, vehicle-client constraints and delivery time windows. The firefly algorithm has been implemented to solve th…
