Decision support for grid-connected renewable energy generators planning
Recent technological advances and the incremental demand for electrical energy are leading a growth in the prevalence of distributed generation. There are some off-the-shelf tools to support grid planners in locating and ...
Constraint satisfaction techniques under uncertain conditions for fault diagnosis in nonlinear dynamic systems
The speed of fault isolation is crucial for the design and reconfiguration of fault tolerant control (FTC). In this paper the fault isolation problem is stated as a constraint satisfaction problem (CSP) and solved using ...
An LMI approach to H∞ synchronization of second-order neutral master-slave systems
The H∞ synchronization problem of the master and slave structure of a second-order neutral master-slave systems with time-varying delays is presented in this paper. Delay-dependent sufficient conditions for the design of ...
Quantified set inversion with applications to control
This paper describes a new reliable method, based on modal interval analysis (MIA) and set inversion (SI) techniques, for the characterization of solution sets defined by quantified constraints satisfaction problems (QCSP) ...
Closed-Loop Control of Postprandial Glycemia Using an Insulin-on-Board Limitation Through Continuous Action on Glucose Target
Background: Postprandial (PP) control remains a challenge for closed-loop (CL) systems. Few studies with inconsistent results have systematically investigated the PP period. Objective: To compare a new CL algorithm with ...
SQualTrack: A Tool for Robust Fault Detection
One of the techniques used to detect faults in dynamic systems is analytical redundancy. An important difficulty in applying this technique to real systems is dealing with the uncertainties associated with the system itself ...
Atributos Relevantes para el Diagnóstico Automático de Eventos de Tensión en Redes de Distribución de Energía Eléctrica = Relevant Attributes for Voltage Event Diagnosis in Power Distribution Networks
This paper focuses on diagnosis of voltage events collected in power distribution networks. Fault networks, induction motor starting, transformer energization and capacitor bank switching cause voltage events. A characterization ...
Case-base maintenance of a personalised and adaptive CBR bolus insulin recommender system for type 1 diabetes
People with type 1 diabetes must control their blood glucose level through insulin infusion either with several daily injections or with an insulin pump. However, estimating the required insulin dose is not easy. Recommender ...
Self-organising energy demand allocation through canons of distributive justice in a microgrid
The energy sector is being driven into a new era where considerable portions of electrical demand will be met through distributed energy resources (DERs). Microgrids have been suggested as a tool for integrating and managing ...
Active control of structures with uncertain coupled subsystems and actuator dynamics
This paper deals with the problem of stabilizing a class of structures subject to an uncertain excitation due to the temporary coupling of the main system with another uncertain dynamical subsystem. A Lyapunov function ...
Dissolution of Dynamic Electronic Institutions, a first approach: Relevant factors and causes
In the context of the digital business ecosystems, small organizations cooperate between them in order to achieve common goals or offer new services for expanding their markets. There are different approaches for these ...
Frequency domain control based on quantitative feedback theory for vibration suppression in structures equipped with magnetorheological dampers
This paper addresses the problem of designing quantitative feedback theory (QFT) based controllers for the vibration reduction in a structure equipped with an MR damper. In this way, the controller is designed in the ...
APPRAISE-RS: Automated, updated, participatory, and personalized treatment recommender systems based on GRADE methodology
Purpose: Clinical practice guidelines (CPGs) have become fundamental tools for evidence-based medicine (EBM). However, CPG suffer from several limitations, including obsolescence, lack of applicability to many patients, ...
Prediction of glucose level conditions from sequential data
In type 1 diabetes management, mobile health applications are becoming a cornerstone to empower people to self-manage their disease. There are many applications addressed to calculate insulin doses based on the current ...
Two methods for voltage sag source location
This paper presents and compares two approaches to estimate the origin (upstream or downstream) of voltage sag registered in distribution substations. The first approach is based on the application of a single rule dealing ...
Dimensionality reduction and features visual representation based on conditional probabilities applied to activity classification
A large part of the information emitted by contemporary technological devices comes in the form of time series. The massive commercialization of these kinds of devices has made the study of time series feature extraction ...
Curriculum sequencing for an e-learning system based on learning styles
This work shows the use of adaptation techniques involved in an e-learning system that considers students' learning styles and students' knowledge states. The mentioned e-learning system is built on a multiagent framework ...
Transmission delays in residual computation
The design of control, estimation or diagnosis algorithms most often assumes that all available process variables represent the system state at the same instant of time. However, this is never true in current network ...
A survey on voltage sag events in power systems
This paper aims to survey the techniques and methods described in literature to analyse and characterise voltage sags and the corresponding objectives of these works. The study has been performed from a data mining point of view
A new perspective of trust through multi-attribute auctions
The use of trust in auctions is a well-studied problem; however, most of the works in the literature focus on how to model trust rather on how trust is used in the mechanism. In this paper we propose a method to manage ...
