Uncertainty-aware Robustness Assessment of Industrial Elevator Systems
(ACM, 2022)
Industrial elevator systems are commonly used software systems in our daily lives, which operate in uncertain environments such as unpredictable passenger traffic, uncertain passenger attributes and behaviors, and hardware ...
Spectrum-based feature localization for families of systems
(Elsevier, 2022)
In large code bases, locating the elements that implement concrete features of a system is challenging. This information is paramount for maintenance and evolution tasks, although not always explicitly available. In this ...
Measurement based Tapped Delay Line Model for Train-to-Train Communications
(IEEE, 2022)
Train-to-train (T2T) communication is proposed as an auxiliary safety-guaranteed measure for railway communications. Vehicular communication standards have been supporting railway use cases and T2T communications. It is ...
A Case Study of Entrepreneurial Intent Among Students of the Primary Education Degree in the Basque Country and the Performance of Education Faculties
(Richtmann, 2022)
Entrepreneurship is a key competence for anyone intending to be an active citizen and obtain employment. Entrepreneurial education is therefore essential at all levels of education and in every field, not only in business ...
Heart-brain synchronization breakdown in Parkinson’s disease
(Springer Nature, 2022)
Heart rate variability (HRV) abnormalities are potential early biomarkers in Parkinson’s disease (PD) but their relationship with central autonomic network (CAN) activity is not fully understood. We analyzed the synchronization ...
Post-forming, electro-plastic effect internal stress reduction in AA5754 aluminium alloy
(Elsevier, 2022)
Aluminium alloys are one of the most efficient materials for weight reduction in the car industry. However, the favourable performance of alloys conflicts with the difficulties of transforming these materials through plastic ...
Li-ion Battery-based Hybrid Diesel-Electric Railway Vehicle: In-depth Life Cycle Cost Analysis
(IEEE, 2022)
In this study, the life cycle costs of railway projects involving hybrid diesel-electric vehicles are analysed. Specifically, the analysis focuses on the comparison of 3 lithium-ion battery technologies (NMC, LTO and LFP) ...
Plasticity evolution of an aluminum-magnesium alloy under abrupt strain path changes
(Springer, 2022)
During the forming and manufacturing of engineering materials, plasticity behavior could be evolving significantly due to complex deformation history. Therefore, this study aims to characterize the plasticity evolution of ...
How Does the Modeling Strategy Influence Design Optimization and the Automatic Generation of Parametric Geometry Variations?
(Elsevier, 2022)
The robustness and flexibility of a feature-based parametric CAD model determines the extent to which the geometry can be modified and reused in other design scenarios. The ability of a model to successfully adapt to changes ...
Double Dead-Time Signal Injection Strategy for Stator Resistance Estimation of Induction Machines
(MDPI, 2022)
A sensorless online temperature estimator is presented in this paper, which estimates the temperature using a novel signal injection strategy. This allows to eliminate the temperature sensors in the machine, as well as ...
