- Importance of auditory training in the development and stimulation of skills in hearing aid users – a systematic review of the literaturePublication . Pereira, Maria José; Barbosa, Ana Catarina; Faria, VeraAuditory rehabilitation performed by psychoacoustic amplification allows for an increase in audibility, however, there may be difficulties in sound perception. Auditory training can be used to improve auditory performance, conse quently improving auditory skills affected by hearing loss. This study aims to understand which skills are developed and/ or stimulated by auditory training in hearing aid users and the importance of this type of training in these individuals.
- Load Profiling Tool to Support Smart Grid Operation ScenariosPublication . Ramos, Sérgio; Praça, Isabel; Vale, Zita; Sousa, Tiago; Faria, VeraThis paper presents the characterization of high voltage (HV) electric power consumers based on a data clustering approach. The typical load profiles (TLP) are obtained selecting the best partition of a power consumption database among a pool of data partitions produced by several clustering algorithms. The choice of the best partition is supported using several cluster validity indices. The proposed data-mining (DM) based methodology, that includes all steps presented in the process of knowledge discovery in databases (KDD), presents an automatic data treatment application in order to preprocess the initial database in an automatic way, allowing time saving and better accuracy during this phase. These methods are intended to be used in a smart grid environment to extract useful knowledge about customers’ consumption behavior. To validate our approach, a case study with a real database of 185 HV consumers was used.
