Cultural Landscape Assessment: The Rural Architectural Heritage (13th–17th Centuries) in Mediterranean Valleys of Marina Alta, Spain
(MDPI, 2018-10-11)
Europe’s cultural heritage is a rich and diverse legacy that shows evolution through many centuries of history. The Mediterranean landscape is the result of a long process of human activity in the physical environment, ...
Multiobjective performance-based designs in fault estimation and isolation for discrete-time systems and its application to wind turbines
(Taylor & Francis, 2019-04-09)
In this work, we develop a performance-based design of model-based observes and statistical-based decision mechanisms for achieving fault estimation and fault isolation in systems affected by unknown inputs and stochastic ...
Trade-offs on fault estimation via proportional multiple-integral and multiple-resonant observers for discrete-time systems
(Institution of Engineering and Technology, 2019-03)
The authors develop a fault estimation strategy which is based on a novel proportional multiple-integral (PMI) and multiple-resonant observer. This observer is an extension of the well-known PMI observer and it is able to ...

Reduced-Order Models of Squirrel-Cage Induction Generators for Fixed-Speed Wind Turbines under Unbalanced Grid Conditions
(Institute of Electrical and Electronics Engineers (IEEE), 2016-06)
This paper develops a study of reduced-order
models for squirrel-cage induction generators (SCIG) used in
fixed-speed wind turbines (WTs). The squirrel-cage of these
generators must be modeled with a double-cage for ...
A multilevel modular dc-dc converter topology
(Elsevier, 2017)
A multilevel modular DC-DC power conversion topology based on cascaded H-Bridge
converters in a double П configuration is presented. The topology is intended to interconnect
large power DC networks. A two level control ...
Assessment of Subsynchronous Oscillations in AC grid-connected VSC Systems with Type-4 Wind Turbines
(The Institution of Engineering and Technology (IET), 2019-10-16)
Converters are the key for the increasing development of renewable energy generation but their dynamic
interaction with the grid has an important impact on stability. Oscillatory instabilities in different grid-connected ...
Towards a comprehensive model for characterising and assessing thermoelectric modules by impedance spectroscopy
(Elsevier, 2018-09-15)
Thermoelectric devices have potential energy conversion applications ranging from space exploration through to mass-market products. Standardised, accurate and repeatable high-throughput measurement of their properties is ...
