Full textIn order to obtain credit for an eco-roof in building energy load calculations the steady state and time-varying thermal properties (thermal mass with evapotranspiration) must be fully understood. The following study presents results of experimentation and modeling in an effort to develop dynamic thermal mass performance metrics for eco-roof systems. The work is focused on understanding the thermal parameters (foliage & soil) of an eco-roof, further validation of the EnergyPlus Green Roof Module and development of a standardized metric for assessing the time-varying thermal benefits of eco-roof systems that can be applied across building types and climate zones.
Eco-roof foliage, soil and weather parameters were continuously collected at the Green Roof Integrated PhotoVoltaic (GRIPV) project from 01/20/2011 to 08/28/2011. The parameters were used to develop an EnergyPlus eco-roof validation model. The validated eco-roof model was then used to estimate the Dynamic Benefit for Massive System (DBMS) in 4 climate-locations: Portland Oregon, Chicago Illinois, Atlanta Georgia and Houston Texas.
GRIPV30 (GRIPV soil with 30% soil organic matter) was compared to 12 previously tested eco-roof soils. GRIPV30 reduced dry soil conductivity by 50%, increased field capacity by 21% and reduced dry soil mass per unit volume by 60%. GRIPV30 soil had low conductivity at all moisture contents and high heat capacity at moderate and high moisture content. The characteristics of the GRIPV30 soil make it a good choice for moisture retention and reduction of heat flux, improved thermal mass (heat storage) when integrating an eco-roof with a building.
Eco-roof model validation was performed with constant seasonal moisture driven soil properties and resulted in acceptable measured - modeled eco-roof temperature validation. LAI has a large impact on how the Green Roof Module calculates the eco-roof energy balance with a higher impact on daytime (measured - modeled) soil temperature differential and most significant during summer.
DBMS modeling found the mild climates of Atlanta Georgia and Houston Texas with eco-roof annual DBMS of 1.03, 3% performance improvement above the standard building, based on cooling, heating and fan energy consumption. The Chicago Illinois climate with severe winter and mild spring/summer/fall has an annual DBMS of 1.01. The moderate Portland Oregon climate has a below standard DBMS of 0.97.

Full textIn hands-free telephony and in teleconference systems, the main aim is to provide agood free voice quality when two or more people communicate from different places.The problem often arises during the conversation is the creation of acoustic echo. Thisproblem will cause the bad quality of voice signal and thus talkers could not hearclearly the content of the conversation, even thought lost the important information.This acoustic echo is actually the noise which is created by the reflection of soundwaves by the wall of the room and the other things exist in the room. The mainobjective for engineers is the cancellation of this acoustic echo and provides an echofree environment for speakers during conversation. For this purpose, scientists designdifferent adaptive filter algorithms. Our thesis is also to study and simulate theacoustics echo cancellation by using different adaptive algorithms.
Carlo, Diego Di. "Echo-aware signal processing for audio scene analysis." Thesis, Rennes 1, 2020. http://www.theses.fr/2020REN1S075.
Full textMost of audio signal processing methods regard reverberation and in particular acoustic echoes as a nuisance. However, they convey important spatial and semantic information about sound sources and, based on this, recent echo-aware methods have been proposed. In this work we focus on two directions. First, we study the how to estimate acoustic echoes blindly from microphone recordings. Two approaches are proposed, one leveraging on continuous dictionaries, one using recent deep learning techniques. Then, we focus on extending existing methods in audio scene analysis to their echo-aware forms. The Multichannel NMF framework for audio source separation, the SRP-PHAT localization method, and the MVDR beamformer for speech enhancement are all extended to their echo-aware versions

Full textUltrafine particles including nanosized enriched with metal(loid)s (PM) are emitted into the atmosphere of industrial or urban areas, these PM can transfer into soil and water ecosystems and have consequences on plant quality and human health. In a global socio-scientific context that regulation on (eco)toxicity of chemicals and public space pressures are recently increased, studies of environmental and health impacts throughout the life cycle of PM are of crucial sanitary concern. The PhD aims first to study metal(loid)s present in the PM: their transfer kinetic and mechanism of phytoavailability, phytotoxicity, and human health risks-ingestion bioaccessibility. Then, through the case of vegetable gardens near an incinerator and a highway in China, a socio-scientific study was performed in order to give suggestions for sustainable environmental and health risk management for these sites. Vegetables can significantly accumulate metal(loid)s by foliar uptake when PM directly enter into leaves through stomata apertures. Ultrafine PbO and nano-CuO particles caused serious phytotoxicity (reduced biomass and gaseous exchange, and necrosis) after interaction with leaf surface. Phytotoxicity of metal(loid)s is not simply governed by their total concentration, but also depended on the potential bio-transformation. Electron paramagnetic resonance (EPR) analysis clearly evidenced copper speciation change in leaf tissues. Moreover, a significant influence of the nature of metal, plant species and the exposure pathways (foliar/root) on gastro-bioaccessibility of metal(loid)s had been demonstrated. For a social-scientific study near waste incinerator and roadside, we found that atmosphere PM fallouts can induce significant metal foliar uptake in addition to soil-plant transfer. The relatively high human bioaccessibility of metal (60-79%) was measured, suggesting a potential health risk in the case of regular consumption of polluted vegetables. Vegetable gardens present a low (waste incinerator) or moderate (highway) health risk with respect to human consumption quantity of the investigated vegetables, but exposure to different organic pollutants in addition to metals is often possible. Our studies highlight the importance of taking atmosphere and soil quality into account for estimating the quality of consumed plants grown in anthropic areas (farms and kitchen gardens), and for sustainable management of urban agricultures

Nowadays, Taiwan had a highly urbanized density , however, when the natural environment turned into the concrete jungle, causing serious imbalance in the ecosystem. In order to improve the deteriorating environment and construct ecology city, government , academic organization and private organizations in Taiwan began to promote the concept of Green Roof ,thereby, they improve the urban environment. However, the development of Taiwan’s Green Roof is in the experimental stage, lack for using ecological angle to research in plant design of Green Roof, lead exotic plant to oppressed native species. It make exotic plant repress the living of native plants. and brings potential threat for local ecosystem. Up to present, the database of Taiwan’s Green Roof is limited, so that the species and height of plant are monotonous, can’t attract organism and design an abundant and colorful landscape of Green Roof from multiple layers vegetation to plant. As the result, this research will explore Taiwan 's Green Roof from an angle of ecological design, the selection of native plants and ecological planting design, As supporting, the case in roof of the Fu Jen catholic university college of arts is used in this research. Research purposes is divided into three: 1. Understanding green roof development and problems in Taiwan through national & abroad cases and past history records. 2. To explore suitable native plants for Taiwan Green roof with experiment on the growth of the plant, results in various of plant selection plan. 3. According to the discussion of the case and with the experimental results , so the ecological planting design of the Green Roof is established. Research was started through discussion on the Green Roof’s past ecological design & other reference historical records. These information was used as a referral & the body on this research. According to the record & the sample experiment, native plant and shrub plays a very important part in the ecological design. Thus, this research was done by experimenting 6 different herbaceous plants & shrubs from the starting date: 2011/08/01 to 2012/1/1. The result of this research shows that the herbaceous plant suits for intensive green roof methods are: Gomphrena globosa,Ajuga pygmaea,Uraria crinite,Indigofera spicata Forsk; plants that suits for extensive green roof method are:Belamcanda chinensis,Sesuvium portulacastrum. For shrubs that suits for semi intensive green roof method are:Crossostephium chinense,Rhodomyrtus tomentosa,Serissa japonica ,Myoporum bontioides, Elaeagnus oldhamii Maxim; shrub suits for extensive method is Schefflera arboricola Hayata. With the issues & resolutions found in initial design process, we can concludes that Green Roof ecological design is best with various kind of native & animal/insect-lure plants that built in multi-layer. This research also suggests various planting method for Green Roof and hoping to be the supporting force of our national Green roof design & development.

Eco-roof is green construction structure consisting of medium soil and plants on top of a building. This research is motivated by the fact that forests and agricultural lands are replaced with impervious surfaces due to urban development in Taiwan, the countermeasures of the green-act should be done soon in order to preserve the health of the environment. Eco-roof technology is one of the appropriate response to cope with this issue. Establishing plant material on rooftops provide numerous ecological and economic benefits including mitigate urban heat island effect, control storm water run-off, reduce sound reflection and transmission, and lower heating and cooling costs, as well as sustain local wildlife. The main objective of this research is to model the influence of eco-roof retrofitting in term of annual energy reduction for a whole building in Taiwan through case study. The method use in this thesis involve whole building simulation model for residential and institutional building. Different type of eco-roof, soil thickness and distinct section assignment of the plant on the roof are parameters used for this research. Results show that different thickness do not directly affect annual energy consumption in the building but more likely has an indirect effect to energy reduction in relation to plants’ selection, in the other word, the larger types of plants the ticker soil need to be applied. Intensive type with the thinner soil layer gives better insulation compare to extensive and even for bare roof. Plants selection and eco-roof coverage design are the biggest factors to lower energy consumption, in this study cases for 5-storey institutional building could reduce energy as much as 24-36% and for 11-storey residential building decrease energy demand around 6-11%.

Abstract Due to the growing phenomenon of global warming, and increasing of air conditioning load in urban areas, it is a very important issue to reduce air conditioning energy consumption effectively and to improve the building energy consumption today. In this study (the fifth floor apartment in Taichung City), the simulated case we use energy simulation software Ecotect to the numerical simulation, such as the different modules of the roof garden, air conditioning situation and the timetable for the simulation project. Then take concrete roof as the comparison, we summed up the best combination of insulation and energy efficiency, and we extended the simulation results to the originalTaichung City for the energy efficiency assessment later. In the generally moderate electricity situations (17-8) of urban housing in Taiwan, the result of research shows 1.The energy efficiency of eco-roof up to 19.5% in full air-conditioning mode. 2.The energy efficiency of eco-roof up to 13.9% in cooling only mode. 3. The energy efficiency of eco-roof up to 23.3% in mixed-mode. 4. If there are 70% of the housing roofs with eco-roofs that we can save maximum of 231,678,021 kWh per year, and consequential to save of NT 906,770,000 dollars. It also reduced the carbon dioxide equivalent emissions of 145,030 metric tons. We can found in this study that the efficiency to save the energy of eco-roof is high,setting the roof garden in the city can save energy effectively and reduce air conditioning load. Keywords:Energy Simulation, Ecotect, Air Conditioning Load, Numerical Limulation.

Full textA biosfera é um organismo vivo onde tudo está interligado. Cada ação tem seu efeito, a gerar um resultado que não tem como ser precisamente previsto. O atual sistema político-socioeconômico faz com que adotemos a idéia de que nossas vidas sejam análogas às máquinas, o que nos impede de ver a magia dos ecossistemas, a magnitude das nossas vidas e a harmonia necessária no todo. Diante de um cenário urbano mundial altamente industrializado e sobrecarregado, em que a relação entre seres humanos e meio ambiente foi degradada pela mentalidade do lucro e pelos processos de produção extrativos contemporâneos, surgem algumas questões: Como resolver o dilema de sustentabilidade causado pela ganância que gera impactos ambientais sem consciência? O que a arquitectura pode fazer para reverter os processos de degradação ambiental? Como superar os prováveis problemas futuros, causados seja pela poluição, desmatamento, superpopulação, ocupação sem planejamento, pandemias, e outras dificuldades ainda irão surgir no caminho da nossa evolução? Estimulados pela consciência ambiental, e evidências de que as emissões de carbono e a ocupação incessante do espaço aumentam a temperatura local e global, examinaremos neste estudo o aspecto arquitetônico de aproveitamento das coberturas e fachadas dos edifícios como um espaço mitigador à poluição, gerador de benefícios para a eficiência do edifício e cabível de produzir, não sendo apenas uma proteção contra intempéries. Esta dissertação tem como objetivo reunir e questionar os modelos projetados e os sistemas construtivos atuais, bem como suas funções adicionais, como a capacidade produtiva das fazendas urbanas e seus benefícios para o meio ambiente e seus habitantes. A agregar valor cientifico, foram analisados dois casos de estudo, sendo um deles na cidade portuguesa de Guimarães e outro na cidade brasileira do Rio de Janeiro, onde se apresenta a proposta de analisar os dados climaticos, conforto térmico e a produção de vegetação e alimentos sobre os protótipos criados para a pesquisa. Certamente, a aplicação da consciêntização ambiental nas etapas de planejamento, na escolha dos materiais, na elaboração do projeto, construção, manutenção e uso sustentável, a obrigação dos arquitectos e engenheiros, a contribuir com a melhoria da qualidade de vida das pessoas na edificação, na cidade, no país e no mundo.
The biosphere is a living organism where everything is interconnected. Each action has its effect, generating a result that cannot be precisely predicted. The current political-socio-economic system makes us adopt the idea that our lives are analogous to machines, which prevents us from seeing the magic of ecosystems and the magnitude of our lives and the necessary harmony in the whole. Faced with a highly industrialized and overburdened global urban scenario, in which the relationship between human beings and the environment has been degraded by the profit mentality and by contemporary production processes, some questions arise: How to solve the sustainability dilemma caused by greed that generates impacts environmental? What can architecture do to reverse the processes of environmental degradation? How to overcome the probable future problems, caused either by pollution, overpopulation, unplanned occupation, pandemics, and other difficulties will still arise in the path of our evolution? Stimulated by environmental awareness, fostered by the Paris Agreement, as well as various laws, protocols, and evidence that carbon emissions and incessant occupation of space increase local and global temperature, in this study we will examine the architectural aspect of using roofs and building facades as a pollution-mitigating and productive space, not just a protection against bad weather. This dissertation aims to gather and question the projected models and the current construction systems, as well as their additional functions, such as the productive capacity of urban farms and their benefits for the environment, cities and their inhabitants. Adding scientific value, two studie of cases were analyzed, one in the Portuguese city of Guimarães and the other in the Brazilian city of Rio de Janeiro, where we propose to analyze the climatic data, thermal comfort and the production of food allowed on the prototypes. Certainly, in the application of environmental awareness in the stages of planning, choice of materials, preparation of the project, construction, maintenance and sustainable use, we will be as architects and engineers, contributing to improving the quality of life of people in the building, in the city, in the country and into the world.

ABSTRACT Upon the digital signal processing and adaptively active control, this study adopts the (IIR) infinite impulse response digital filter as the systematic structure which combines with the (NLMS) normalized least-mean-square algorithm so as to carry on an optimize operation. To set up the acoustic-echo cancellation system for this study, the combination of the LabVIEW program and A/D-D/A converter data acquisitive equipment with personal computer is used as the required platform. For the experiment of the acoustic-echo cancellation, an enclosure with highly reflective walls is used as the experimental site, and the selected input signals both of pure-tones and random. The system performances are identified by comparing the methods to set up the parameter of system, its operation performance and their influence on the effectiveness of echo cancellation for various frequencies. Experimental results show that the ERLE by 20 to 50 decibels for various frequencies form low to high pure-tone sounds are reached. The reductions of echo power spectrum by more than 60 decibels are reached. As regards to the case of randomly acoustic echo, either the ERLE by 2 to 10 dB or the reduction of centre frequency by 3 to 15 dB is achieved. Moreover, for the case of narrow-band acoustic echo, either the ERLE by 13 to 18 dB or the reduction of centre frequency by 10 to 17 dB is achieved.

"Can one hear the shape of a room?" is asked and investigated by Dokmanic et al.. In this thesis, Dokmanic et al.'s original way of echo labeling by alternating coordinate descent is compared with quasi-Newton and trust-region methods. To test performance of the methods, a sound-emitting device arbitrarily connecting four receivers that hear the echoes is placed in three different rooms in simulation. Under the assumptions that the room impulse responses could be successfully estimated and their peaks could be perfectly selected, the whole process for the room shape estimation is tested with 100 random settings. The estimated shape of the rooms via the three methods are roughly characterized as "good", "bad", or "failed". They are compared in different performance indices, including the execution time, the magnitude of error for non-failed results and the frequency of occurrences of failed results. Other implementation details like the termination criteria, the handling of multiple solutions, and the error estimation are also reported.
