Abstract:

Nesta tese avaliei a relação entre a classificação de riachos em tipos de rios baseados nas suas características abióticas com a comunidade de macroinvertebrados. Especificamente, avaliei as seguintes questões: 1) Como as escalas de trecho de rio (local) e de bacia hidrográfica (regional) influenciam as comunidades? 2) As classificações de rios baseadas em variáveis abióticas são concordantes com aquelas baseadas em macroinvertebrados? 3) As respostas das comunidades de macroinvertebrados são similares quando diferentes abordagens de classificação são usadas?

Abstract:

This thesis develops an adaptive environmental classification system for hearing aids. Two types of classifiers, minimum distance and Bayesian, are modified to include an adaptive layer that allows the classes to split or merge based on changes in the environment. In order to test the adaptability to the environmental change, both systems were first trained using two classes: Speech and Noise, followed by a testing period where, in addition to Speech and Noise, samples from a third class Music were introduced. Both systems were successful in detecting the presence of the new class Music and es

Abstract:

The growth of multimedia content in recent years motivated the research on audio classification and content retrieval area. In this thesis, a general environmental audio classification and retrieval approach is proposed in which higher level semantic classes (outdoor, nature, meeting and violence) are obtained from lower level acoustic classes (emergency alarm, car horn, gun-shot, explosion, automobile, motorcycle, helicopter, wind, water, rain, applause, crowd and laughter). In order to classify an audio sample into acoustic classes, MPEG-7 audio features, Mel Frequency Cepstral Coefficients

Abstract:

Document classification is used to sort and label documents. This gives users quicker access to relevant data. Users that work with large inflow of documents spend time filing and categorizing them to allow for easier procurement. The Automatic Classification and Document Filing (ACDF) system proposed here is designed to allow users working with files or documents to rely on the system to classify and store them with little manual attention. By using a system built on Hidden Markov Models, the documents in a smaller desktop environment are categorized with better results than the traditional N

Sound is one of a human beings most important senses. After vision, it is the sense most used to gather information about the environment. Despite this, comparatively little research has been done into the field of sound recognition. The research that has been done mainly centres around the recognition of speech and music. Our auditory environment is made up of many sounds other than speech and music. This sound information can be taped into for the benefit of specific applications such as security systems. Currently, most researchers are ignoring this sound information. This thesis investigat

Environmental response to acidic deposition occurs through the vehicle of water movement in the ecosystem. As a part of the environmental studies for acidic deposition in the ecosystem, output-based hydrologic classification was done from basin hydrologies based on the distribution of the baseflow, snowmelt, and the direct runoff sources. Because of the differences in the flow paths and exposure duration, those components were assumed to represent distinct geochemical responses. As a first step, user-friendly software has been developed to calculate the baseflow based on the separation of annu

Environmental studies often employ data collected over large spatial regions. Although it is convenient, the conventional single model approach may fail to accurately describe the relationships between variables. Two alternative modeling approaches are available: one applies separate models for different regions; the other applies hierarchical models. The separate modeling approach has two major difficulties: first, we often do not know the underlying clustering structure of the entire data; second, it usually ignores possible dependence among clusters. To deal with the first problem, we propo

Abstract:

Le volume des données ne cesse de croître. À tel point qu'on parle aujourd'hui de "Big Data". La principale raison se trouve dans les progrès des outils informatique qui ont offert une grande flexibilité pour produire, mais aussi pour stocker des quantités toujours plus grandes. Les méthodes d'analyse de données ont toujours été confrontées à des quantités qui mettent en difficulté les capacités de traitement, ou qui les dépassent. Pour franchir les verrous technologiques associés à ces questions d'analyse, la communauté peut se tourner vers les techniques de calcul distribué. En particulier,

Master of Public Health<br>Department of Diagnostic Medicine/Pathobiology<br>Deon Van der Merwe<br>Cyanobacteria are Gram-negative photosynthetic bacteria capable of producing toxins responsible for morbidity and mortality in humans and domestic animals. Many are capable of forming concentrated blooms that impact the environment by limiting the growth of sub-surface plants and phytoplankton. Harmful algal blooms (HABs) are also capable of producing multiple types of toxins, creating a potential hazard to recreational water users and animals drinking water from or near a bloom. Characterization

Abstract:

Purpose/aim: The purpose of this dissertation is to find out the effect of waste disposal on environment and to explore the effect of renewable resources on economy. We use some data to test and verify the existence of effects. Design/methodology/approach: We use our questionnaires to collect data, and analyze the data in statistical tests. We use case studies to find examples to verify the significance of waste classification and renewable resources as well as the problems in main cities of China. Findings: The analysis shows that we need to focus on waste classification education, if we want
