Solving the Optimal Reactive Power Dispatch Problem through a Python-DIgSILENT Interface
(Cartagena de Indias, 2022-07-25)The Optimal Reactive Power Dispatch (ORPD) problem consists of finding the optimal settings of reactive power resources within a network, usually with the aim of minimizing active power losses. The ORPD is a nonlinear and ... -
Spatio Temporal Filtering of Multi-lead ECG Signals for Atrial Arrhythmia Classification
(Cartagena de Indias, 2021-10)Atrial fibrillation (AF) is the most common cardiac arrhythmia and increases the risk of suffering stroke. Some people with AF do not have symptoms, so, its diagnosis can be difficult, especially in early stages of the ... -
Spatio-Temporal Filtering for Evoked Potentials Detection
(Springer, 2020)We propose the new application of the spatio-temporal filtering (STF) method, which is a detection of visual evoked potentials applied to brain-computer interfaces (BCI). STF aims in creating a new, enhanced channel basing ... -
Speckle free optical watermarking based on pseudo-random phase encoding
(Institute of Electrical and Electronics Engineers Inc., 2016)Watermarking is a process of embedding copiright information into an image to verify the ownership without any kind of corruption. In optical applications, the usage of diffusers is required to obtain a homogeneously ... -
Speckle interferometry single-shot applications with multiple carrier-fringe information
(Cartagena de Indias, 2023-06-15)The need for robust equipment that allows identifying defects or measuring small displacements in a harsh environment has been a requirement in the aeronautical and principally in the Oil & Gas industry. In this field, ... -
Speckle reduction in echocardiography by temporal compounding and anisotropic diffusion filtering
(SPIE, 2015)Echocardiography is a medical imaging technique based on ultrasound signals that is used to evaluate heart anatomy and physiology. Echocardiographic images are affected by speckle, a type of multiplicative noise that ... -
Speed of International Expansion: The Mediating Role of Network Resources Mobilisation
(Cartagena de Indias, 2022-08)Multinational Enterprises (MNEs) are often under pressure to expand at the highest possible speed in international markets. They therefore embed themselves in networks of alliances where they can access resources in the ... -
SPUD: Simultaneous phase unwrapping and denoising algorithm for phase imaging
(Cartagena de Indias, 2020-05-01)Recent methods for phase unwrapping in the presence of noise include denoising algorithms to filter out noise as a preprocessing stage. However, including a denoising stage increases the overall computational complexity ... -
