Alzheimer's disease (AD) is one of the main causes of dementia in the world and the patients develop severe disability and sometime full dependence. In previous stages Mild Cognitive Impairment (MCI) produces cognitive loss but not severe enough to interfere with daily life. This work, on selection of biomarkers from speech for the detection of AD, is part of a wide-ranging cross study for the diagnosis...
Alzheimer's disease (AD) is the most prevalent form of progressive degenerative dementia. Its diagnosis made by analyzing many biomarkers and test but nowadays a definitive confirmation requires a post-mortem examination of the patients' brain tissue. The purpose of this paper is to examine the potential of applying intelligent algorithms to the results obtained from non-invasive analysis methods...
The conservation and preservation of biodiversity, its global and fair use, ensures the survival of the planet and ultimately ours. Taken into account the tools provided by scientific and technological developments and increasing concern for environmental conservation, it is of great relevance to identify appropriate technological tools for environmental sustainability. Moreover it is essential establishing...
One of the goals of Speech Recognition Security (SRS) systems is to have appropriately tools to recognize speech password spoken based on elements such as words, sub-word or speakers. The main goal of the present work is to design robust ASR systems based on alternative ways to the classical evaluation rates, which often depend on the vocabulary of the task and on the language resources available...
It Kokoro means, “heart” in Japanese. It also means “mind”, “soul”, “sensibility”, “wishes” and “sentiments”. All of these belong to the wide range of emotions and concepts that define the complex human condition. To be influenced by emotions is intrinsic to a human being. Emotions arise from having to face up to a changing and partially unpredictable world. This makes it necessary for all intelligent...
The long term goal of our project is the development of robust Security Speech Recognition systems are based on Automatic Speech Recognition methodologies. The development of ASR systems involves dealing with issues such as Acoustic Phonetic Decoding (APD), Language Modelling (LM) or the development of appropriated Language Resources (LR). Thus these applications are generally very language-dependent...
It is significant to highlight that the demand of multilingual systems in human-computer interfaces is growing and automatic language identification (LID) is becoming increasingly important for the speech community as a fundamental tool to enrich theses systems. Research in this field has been active for several years. LID becomes also a useful resource in Multilingual Security System (MSS) providing...
One of the goals of speech recognition security (SRS) systems could be to extract the subject of the discourse in order to detect possible risks. Thus, the development of appropriated Speech Semantic Recognition systems is one of the challenges the scientific community has. Our system is an Information Retrieval system that provides information about the contents of audio in Basque, Spanish, and French...
A wireless sensing network Bluetooth enabled was designed and implemented for continuous monitoring of indoor humidity and temperature conditions as well as to detect pollutant gases and vapors. The novelty of the work is related to the development of an embedded software using Java2ME technology for a smart phone that materializes a user friendly HMI. Two mobile software modules assure sensor nodes...
The challenges of power deregulation in Brazil were a predominantly hydroelectric system characterized by large reservoirs capable of multiyear regulation arranged in complex cascades over several river basins. This article briefly diagnoses what went wrong with the Brazilian reform, contrasts its approach with that of California, and discusses alternatives to improve the situation.
The objective of this paper is to investigate market power issues in bid-based hydrothermal scheduling. Initially, market power is simulated with a single-stage Nash-Cournot equilibrium model. Market power assessment for multiple stages is then carried through a stochastic dynamic programming scheme. The decision in each stage and state is the equilibrium of a multi-agent game. Thereafter, mitigation...
