The spheroidal trackball: generalising the fixed trackball for virtual camera navigation
(Springer Nature, 2024-02-27)Virtual trackball techniques have become a standard in 3D applications, particularly for interfaces with limited degrees of freedom such as touchscreens or mice. The fact that we are used to them does not mean that they ... -
Simultaneous wireless power and data transfer for electric vehicle charging: a review
(IEEE, 2023)Wireless charging of Electric Vehicles (EVs) has become an important research topic in recent years. During the wireless charging process, wireless data exchange must take place between the EV and the charging station. ... -
A new pyramid-based color image representation for visual localization
(Elsevier, 2010)This paper presents a new algorithm to extract a color graph from a real image so that it can be efficiently represented in a compact way. The proposal presents two main novelties. First, a new PCA-based color feature ... -
FPGA-Based CNN for Eye Detection in an Iris Recognition at a Distance System.
(2023-11-20)Neural networks are the state-of-the-art solution to image-processing tasks. Some of these neural networks are relatively simple, but the popular convolutional neural networks (CNNs) can consist of hundreds of layers. ... -
Real-time embedded eye detection system
(Elsevier, 2022-05)The detection of a person’s eyes is a basic task in applications as important as iris recognition in biometric identification or fatigue detection in driving assistance systems. Current commercial and research systems use ... -
Vision-based techniques for automatic marine plankton classification.
(2023-03-25)Plankton are an important component of life on Earth. Since the 19th century, scientists have attempted to quantify species distributions using many techniques, such as direct counting, sizing, and classification with ... -
On managing knowledge for MAPE-K Loops in self-adaptive robotics using a graph-based runtime model
(MDPI, 2022-08)ervice robotics involves the design of robots that work in a dynamic and very open environment, usually shared with people. In this scenario, it is very difficult for decision-making processes to be completely closed at ... -
Data-driven multiresolution camera using the foveal adaptive pyramid
(MDPI, 2016-11)There exist image processing applications, such as tracking or pattern recognition, that are not necessarily precise enough to maintain the same resolution across the whole image sensor. In fact, they must only keep it as ... -
Reverse decomposition method vs simplified photovoltaic module electrical model comparison.
(Elsevier, 2017-11-04)The resolution of the Photovoltaic modules electrical using mathematical models can be addressed in different ways. Depending on the degree of precision required, several options are available, which will require more or ... -
Real-Time Embedded Eye Image Defocus Estimation for Iris Biometrics
(MDPI, 2023-08-29)One of the main challenges faced by iris recognition systems is to be able to work with people in motion, where the sensor is at an increasing distance (more than 1 m) from the person. The ultimate goal is to make the ... -
A Resonant Ring Topology Approach to Power Line Communication Systems within Photovoltaic Plants
(MDPI, 2022-08-09)Within this study, single-cable propagation facilitated by PV strings’ wiring characteristics is considered for an adapted design of PLC electronics. We propose to close the communications signal path, resulting in a ring ... -
Dynamic reconfiguration to optimize energy production on moving photovoltaic panels.
(MDPI, 2023-07-11)Urban transport systems play a major role in the development of today’s societies, but they require technological changes to reduce their environmental impact. The problem lies in their level of autonomy, which is why ... -
New model to study the outdoor degradation of thin–film photovoltaic modules.
(Elsevier, 2022-05-19)The performance of four thin-film photovoltaic modules is analyzed after an initial stabilization period and a subsequent outdoor exposition. The seasonal variations and the degradation rates of a single-junction ... -
