On benchmarking the dependability of automotive engine control applications
2004
The pervasive use of ECUs (electronic control units) in automotive systems motivates the interest of the community in methodologies for quantifying their dependability in a reproducible and cost-effective way. Although the core of modern vehicle engines is managed by the control software embedded in engine ECUs, no practical approach has been proposed so far to characterise the impact of faults on the behaviour of this software. This paper proposes a dependability benchmark for engine control applications. The essential features of such type of applications are first captured in a general model, which is then exploited in order to specify a standard procedure to assess dependability measure…

Transcultural adaptation and validation of Italian Selfcarediabetic foot questionnaire
2021
[Abstract] The Italian Self care diabetic foot questionnaire, (SDFQ-IT) is considered a dia-betic foot self-care evaluation tool with 16 questions for assessing diabetic foothealth disorders. To date, SDFQ has been validated in different languages, butan Italian version was lacking. Consequently, the purpose of this study was totranslate and validate the Italian version of the SDFQ-I T (SDFQ-IT). A suitablemethod was developed for the translation protocol and cross-cultural valida-tion from Spanish to Italian. Regarding the total marks from each sub-scale,agreement degrees, and confidence were analysed using the Cronbach's α andintraclass correlation coefficient (IC C), respectively. In add…
Analysis of operator human errors in hydrogen refuelling stations: Comparison between human rate assessment techniques
2013
Abstract The use of hydrogen as an energy carrier for road transport appears to be an optimal solution for the reduction of greenhouse gas emissions. Nevertheless, the development of this technology depends on the growth and diffusion of production, storage and refuelling infrastructures together with accurate risk analyses to appropriately design the safety and management systems used in these plants. Moreover, to improve safety standards, it is also important to focus attention on the estimation of hazards related to human factors, as this is one of the major causes leading to accidental events, especially in complex industrial technology. The paper reports a case study relevant to operat…
Early-stage thermal performance design of thermo-active walls implemented in underground infrastructures
2022
Abstract Energy geostructures (EGs) represent an innovative technology in the sustainable energy agenda and are useful for satisfying the energy needs of the built environment. They are usually involving geostructures such as piles, walls, tunnels, shafts, and sewers. The application of such technology to infrastructure projects may have considerable thermal potential because of the large surfaces that can be thermally activated. This study focuses on thermo-active walls (energy walls, EWs), which are retaining structures used to sustain the sides of excavations. Key features related to their thermal design are examined, and a design methodology is proposed. The heat-exchange modes involvin…
Experimental analysis of a thermoactive underground railway station
2022
Little is known about the real energy potential of thermoactive underground infrastructures, such as railway stations, that can act as a heating/cooling provider for the built environment. This study presents the results of thermomechanical full-scale in situ testing and numerical analysis of a thermoactive underground train station. The thermal performance and related geostructural impact of a portion of the new underground energy infrastructure (UEI) installed at the Lancy-Bachet train station in Geneva (Switzerland) are analyzed. Heating and cooling tests simulating real operative geothermal conditions are considered. Particular attention is given to ((i) the monitored wall-tunnel hydrot…
Domestic load forecasting using neural network and its use for missing data analysis
2015
Domestic demand prediction is very important for home energy management system and also for peak reduction in power system network. In this work, active and reactive power consumption prediction model is developed and analysed for a typical Southern Norwegian house for hourly power (active and reactive) consumptions and time information as inputs. In the proposed model, a neural network is adopted as a main technique and historical domestic load data of around 2 years are used as input. The available data has some measurement errors and missing segments. Before using the data for training purpose, missing and inaccurate data are considered and then it is used for testing the model. It is ob…
ERCP : Energy-Efficient and Reliable-Aware Clustering Protocol for Wireless Sensor Networks
2022
Wireless Sensor Networks (WSNs) have been around for over a decade and have been used in many important applications. Energy and reliability are two of the major problems with these kinds of applications. Reliable data delivery is an important issue in WSNs because it is a key part of how well data are sent. At the same time, energy consumption in battery-based sensors is another challenge. Therefore, efficient clustering and routing are techniques that can be used to save sensors energy and guarantee reliable message delivery. With this in mind, this paper develops an energy-efficient and reliable clustering protocol (ERCP) for WSNs. First, an efficient clustering technique is proposed for…
VALIDITY, RELIABILITY AND FEASIBILITY OF MEASURING MUSCLE ACTIVITY WITH TEXTILE ELECTRODES EMBEDDED INTO CLOTHING
2007
INTRODUCTION In out-of-laboratory settings the surface EMG measurements are complicated by the requirement of careful electrode placement and skin preparation. The development of washable textile electrodes that can be sowed into sportswear enable muscle activity recordings during normal locomotion without skin preparation and the problem of wires hanging around the body [1]. In this study we performed validity, reliability and feasibility tests of the textile electrodes embedded into shorts against the traditional bipolar surface electrodes.
A DSP-Based Resolver-To-Digital Converter for High-Performance Electrical Drive Applications
2016
This paper presents a low cost, simple, and highly accurate resolver-to-digital converter (RDC) for electrical drive applications based on an integrated software approach, thus allowing a significant reduction of hardware components count with significant improvements in terms of reliability, reduction of fault rate, and susceptibility to electromagnetic interference (EMI). Particular attention has been addressed to cost which is 25% off over conventional RDC. Simulations and experimental tests confirm the high quality of the proposed system.
