Evaluation of different flow stress laws coupled with a physical based ductile failure criterion for the modelling of the chip formation process of Ti-6Al-4V under broaching conditions
(Elsevier, 2019)
During the machining of Ti-6Al-4V the changing deformation mechanisms produce a complex microstructure of segmented chips, which directly influenced tool-wear and process stability. Numerical simulation could give an insight ...
The district energy-efficient retrofitting of Torrelago (Laguna de Duero - Spain)
(IOP Publishing, 2019)
The urban growth is estimated to reach up the 66 % by 2050 and consequently the need of resources within the cities will increase significantly. This, combined with the 40 % of energy consumption and 36 % of CO2 emissions ...
Impedance-Based Stability Evaluation of Virtual Synchronous Machine Implementations in Converter Controllers
(IEEE, 2018)
This paper presents a stability evaluation of two Virtual Synchronous Machine (VSM) implementations in the control of Voltage Source Converters (VSCs): a current-controlled (CCVSM) and a voltage-controlled (VCVSM) version ...
Emakumearen mututasun soziala: feminitatearen eta maskulinitatearen estereotipoak
(UEU, 2017)
Most of the main gender stereotypes that nowadays are still alive can already be discovered in Ancient Greece society. In this paper we will analyze Greek symbolic though using genderperspective. We want to unveil the ...
Model driven Hardware-in-the-Loop Fault analysis of railway traction systems
(IEEE, 2017)
Classical Dependability Analysis techniques, such as Failure Mode and Effects Analysis (FMEA) and Fault Tree Analysis, have been used during the last decades to demonstrate the reliability, availability, maintainability ...
Automatic detection test of current sensor faults for induction motor drives at standstill
(IEEE, 2016)
This paper proposes an automatic detection test of gain faults in current sensors. An offline test is applied when the machine is not operating. The designed test operates at standstill without being necessary to disconnect ...
Exekuzio Denboran barne egoera ikusi eta aldatzea ahalbideratzen duten UML Egoera Makinak
(UEU, 2019)
In current industrial environments, the software of embedded systems have to cope with the increasing complexity and robustness requirements at runtime. One way to manage these requirements is having the software component’s ...
Elektrospinning bidezko PCL nanozuntzen lorpena larruazal-birsorkuntzarako
(UEU, 2019)
Skin ulcers are a serious threat to public health system, and, although wound healing is a natural process, a proper dressing can improve the healing process. In this work, platelet rich plasma (PRP) coated polycaprolactone ...
Bateriaren Zahartzeaz Kontziente den Energiaren Kudeaketako Estrategiaren Sentsibilitate-Analisia
(UEU, 2019)
The aim of this paper is to present the sensitivity analysis of a battery ageing conscious energy management strategy. The initial design of an energy management strategy is a significant point, in order to fulfil the ...
DC-link sensor Fault Detection and isolation for railway traction electric drives
(IEEE, 2017)
This article presents the design and the implementation of a fault detection and isolation strategy for sensors in variable speed drives. Electric drives use several current and voltage sensors for control and protection. ...
