Pełny tekst źródłaForests are a key element in the Portuguese landscape. Moreover, fire hazard is a central challenge at national context. How can appropriate management potentially change fire behaviour, fire damage and the difficulty of fire suppression? What are the causal relationships between fire proneness, stand structure and forest stand composition? The common objective of the doctoral research among the five studies is to address the above issues based on principles of creating fire-resistant forests, underlying factors and implications for active forest management, while sustaining effective fire prevention levels. The ultimate goal is to provide forest managers and policy makers with tools to support their decisions, and more effectively align management policies, plans, and practices across fire-prone landscapes. The first research phase aims, across a range of scales from the individual tree to the stand level, respectively: (i) modelling the annual probability of wildfire occurrence of pure and even-aged eucalypt stands; (ii) developing a shrub biomass accumulation model, and (iii) a post-fire mortality model at stand level and the individual tree survival probability to mitigate damage in any forest stand structure. The second phase introduces fire behavior modeling coupled with common stand variables as a tool to (iv) assess potential crown fire occurrence through stand structure/stand composition, and (v) draw guidelines that express the difficulty of fire suppression in those fire-prone forest stands. The accuracy of the research findings can provide an interesting insight to support hazard-reduction silvicultural practices in Portuguese ecosystems

Pełny tekst źródłaNucleation process occurs naturally at savannic areas as of the changes promoted by scattered trees that facilitate the colonization of crown area by new individuals and species, including species typical of forest environment. This process can be influenced by several factors such as the physical characteristics of the nuclei, the species of nucleus and the response of nuclei and colonizers to fire. The aim of this study was to describe the nucleation process in savannic environment of Cerrado, from: the description of the environmental changes promoted by nuclei at crown area and the influence of these changes, as well as the physical parameters (crown area and distance from forest formation) of nuclei, in the structure and composition of the community colonizing nuclei (Chapter 1); the analysis of the influence of fire on the structure, composition, functional diversity and resilience of the community colonizing nuclei (Chapter 2); and the description of the influence of the difference in the species of nucleator in the structure, composition, functional diversity and response to fire of communities colonizing the three species of nuclei. Scattered trees at savannic environments of Cerrado act as nucleating, favoring the crown area colonization by a denser and more diverse community, especially by those species typical of forest environment. The fire alters the structure and composition of the community colonizing the nuclei, which has become less dense and more diverse than the community colonizing this environment before the fire, as well as increasing functional diversity based on richness and the occurrence of resprount among individuals colonizing the community after the fire. The larger the capacity of the nucleator, regardless of species, of generating greater shading, higher humidity and higher nutrient availability, denser and more diverse the community colonizing the nuclei will be.
A nucleação ocorre de forma natural nas áreas savânicas a partir das modificações promovidas pelos indivíduos arbóreos que facilitam a colonização do ambiente abaixo da copa por novos indivíduos e espécies, incluindo espécies típicas de ambiente florestal. Este processo pode ser influenciado por vários fatores como, as características físicas do indivíduo nucleador, a espécie nucleadora e a resposta dos indivíduos nucleadores e colonizadores ao fogo. O objetivo deste estudo foi descrever o processo de nucleação em ambiente savânico do Cerrado, a partir da: descrição das modificações ambientais promovidas pelos indivíduos nucleadores na área da copa e a influência destas modificações, bem como dos parâmetros físicos dos núcleos (área da copa e distância até a formação florestal), na estrutura e composição da comunidade colonizadora dos núcleos (Capítulo 1); análise da influência do fogo na estrutura, composição, diversidade funcional e resiliência da comunidade colonizadora dos núcleos (Capítulo 2); e descrição da influência da diferença das espécies nucleadoras na estrutura, composição, diversidade funcional e resposta ao fogo das comunidades colonizadoras das três espécies nucleadoras. Os indivíduos arbóreos do cerrado sentido restrito atuam como nucleadores favorecendo a colonização da área da copa por uma maior densidade e diversidade de espécies, especialmente aquelas típicas de ambiente florestal. A ocorrência de fogo altera a estrutura e composição desta comunidade colonizadora dos núcleos, que se apresenta menos densa e com maior riqueza que a comunidade colonizadora deste ambiente antes do fogo, além de aumentando a diversidade funcional baseada na riqueza e a ocorrência de rebrota entre os indivíduos que compõem a comunidade após o fogo. Quanto maior for a capacidade do indivíduo nucleador, independente da espécie, de gerar maior sombreamento, maior umidade e maior disponibilidade de nutrientes, mais densa e mais diversa será a comunidade colonizadora deste núcleo.

Pełny tekst źródłaRequests from the firefighting communities are increasing urging the scientific communities to create operational protective and preventive tools that help them understand extreme wildfire behaviors considering not only the atmospheric conditions but also topography, and vegetation characteristics. Thus, our objective was to provide answers to such requests by investigating the probable factors responsible for intensifying wildfire regimes to flashovers using numerical, and thermobiochemical experimental approaches. The numerical model is a gas dispersion model validating experimental data from wind tunnel tests to resolve the controversy of whether or not the volatile organic compounds (VOCs) accumulations in confined topographies end up inducing wildfire flashovers. It comprises a propagating fire front calculated using the Rothermel semi-empirical steady-state surface fire model, and Van Wagner transition to crown fire behavior criteria, with an integrated unsteady rate of VOC emissions simulating the ones evolving from the vegetation burning in the firefront. To synchronize our work with field input, thermochemical experiments were conducted on various Mediterranean vegetation species to examine their VOC emission rates in normal and stressful environmental conditions as they may end up defining different flammability scenarios in wildfires. First, two Mediterranean shrub species: Cistus albidus and Rosmarinus officinalis are explored for their VOC emissions and physiological changes after being subjected to abiotic stresses (drought and heat), using pyrolysis-gas chromatography and mass spectrometry (Py-GC/MS) analyses. Two other Mediterranean forest species: Quercus suber L. and Cupressus sempervirens horizontalis L. were investigated for their distinctive flammability characteristics using thermo-gravimetric and differential thermal analyses (TG/DTA), coupled with Py-GC/MS analysis to identify the gases emitted during the exo-thermic peaks. This step aims to better understand the flammability descriptors of these species as a part of a more efficient forest management strategy by which, favoring the plantation of certain lesser flammable species in silviculture measures may protect other more flammable but economically valuable species, from the dangers of wildfires and their extreme behaviors. Mediterranean vegetation species are important VOC emitters especially when provoked by external stresses during wildfires however, some biogenic VOCs (BVOCs), more particularly sesquiterpenes, are still not thoroughly covered for their flammability characteristics, such as their lower and upper flammability limits, auto-ignition temperatures, flashpoints, etc. Such a scientific lack we found it necessary to enrich by studying the flammability limits of β-Caryophyllene, one of the most important sesquiterpenes emitted from Mediterranean vegetation. Preliminary tests for measuring the vapor pressures of β-Caryophyllene are conducted in preparation for experimenting its flammability limits in a spherical bomb as future plans. The work in this thesis should be considered as the first step in a more global approach that should provide operational firefighting staff, with a comprehensive decision-making tool capable of shaping their forest management strategies from wildfire characteristics themselves and protecting wildlands and firefighters equally from the dangers and extreme behaviors of wildfire flashovers

Pełny tekst źródłaEldsvådor är både livsfarliga och svåra att modellera i verkliga livet. Med hjälp av datorsimulerade folkmassor kan resultatet av en evakuering under eldsvåda observeras utan att försätta försökspersoner i fara. Mycket av den tidigare forskningen inom området räknar dock inte med faktumet att evakuerande människor inte rör sig med konstant hastighet, utan att de i själva verket springer för att fly undan fara. Syftet med denna studie är att undersöka hur resultatet av en simulerad evakuering från en klassrumsmiljö påverkas av att agenter kan öka sin hastighet i närheten av en eldsvåda. Spelmotorn Unity3D användes för att köra simulerade evakueringar från tre olika klassrum, med litet, mellanstort och stort antal sittplatser och motsvarande antal agenter. Ett eldobjekt, som antingen kunde förbli orörligt eller sprida sig genom rummet, placerades på två olika platser i varje rum: nära utgången respektive i ett hörn långt bort från utgången. För var och en av dessa konfigurationer kördes simulationer både med och utan möjligheten för agenter att dynamiskt öka sin hastighet. Evakueringstiden och antalet dödsfall noterades. Experimentet visade att möjligheten för agenter att röra sig snabbare i närheten av ett hot ledde till kortare evakueringstider och färre döda, jämfört med när agenterna begränsades till konstant hastighet. Detta står i motsägelse till data från verkliga livet, som visar att försök att röra sig snabbare vid flykt kan leda till långsammare evakueringar till följd av trängsel. Avvikelsen beror sannolikt på brister i modelleringen av friktion och knuffande beteende mellan agenter. Tydliga skillnader observerades dock gentemot experimenten med konstant hastighet, vilket tyder på vikten av vidare forskning i detta förbisedda område i strävan att skapa verklighetstrogna simuleringar av nödsituationer.

The literature on the stained glass windows installed in the eight oculi of the drum of Santa Maria del Fiore are mainly found in the monographs of the four artists that provided the cartoons--Donatello, Lorenzo Ghiberti, Paolo Uccello, and Andrea del Castagno. Few studies have focused on the program in its entirety. This thesis will attempt to provide a more thorough understanding of the program. Analysis of the primary documents reveals how the windows functioned as part of the building and its liturgical and public life. In particular, the central argument is that Donatello's Coronation of the Virgin was a substitute for an altarpiece and the seven other windows act as subsidiary scenes that reinforce the primary window and its political and theological agenda.

Pełny tekst źródłaEste estudo foi realizado no âmbito dos fenómenos de comportamento extremo de fogo, em que se pretendeu analisar as condições envolvidas na transição de fogo de superfície para fogo de copas e criar um guia de determinação de um potencial de ocorrência de focos secundários. A análise da ocorrência de fogos de copas baseou-se na determinação da perda de massa média das árvores durante a queima e na medição das velocidades de escoamento convectivas, da temperatura e da velocidade de propagação. Os parâmetros calculados foram conclusivos, na medida que foi possível retirar informação sobre a sua evolução ao longo do ensaio, facilitando a leitura/análise dos dados, de modo a perceber de que forma as condições iniciais de cada ensaio influenciam estes parâmetros. No que diz respeito aos focos secundários, o guia criado incide com maior importância no potencial de libertação de partículas incandescentes, no entanto a avaliação da fase de transporte de partículas incandescentes e a probabilidade de ignição também são incluídas no guia. Foram atribuídas classes de formação de combustíveis para povoamento de herbáceas, matos, pinhais, eucaliptos, folhosas caducifólias e resíduos de exploração, resultando ainda a subdivisão de algumas classes em situações mais específicas de cada povoamento, verificando-se que estas mesmas classes são povoamentos característicos da zona centro de Portugal Continental. O desenvolvimento deste guia, tendo-se baseado num guia de combustíveis já existente (Cruz, 2005), ainda se encontra em fase de exploração, pelo que os valores para o potencial de focos secundários apresentados deverão ser desenvolvidos posteriormente. Para cada classe de formação de combustíveis são apresentados diversos fatores, como as características do combustível com potencial de libertação de partículas incandescentes, as características dos povoamentos e o ambiente de fogo, sendo possível estimar a influência destes fatores no potencial de ocorrência de focos secundários nas fases de libertação e transporte de partículas incandescentes seguido de uma possível ignição.
This paper was carried in the context of extreme fire behaver and have the aim of analyzing the conditions involved in the transition from surface fire to crown fire and also to create a guide for determining the release potential of burning embers that can cause spotting. The analysis of crown fire situations is based on the determination of the trees average mass loss when they are burning and the measurement of convective flow velocities, temperature and propagation velocity. The calculated parameters were conclusive since it was possible to take information about their variation throughout the trial and so the reading of data became easier, in order to understand how the initial conditions for each test influence these parameters. Regarding spotting, the guide that was created in this paper as it focus in release potential of burning embers, however the phase of incandescent particles transport and the ignition probability are also included in the guide. There was created in the guide, classes of fuel for populations containing herbaceous, shrubs, pine trees, eucalyptus trees, deciduous broadleaf and operational waste, resulting in more specific situations, characteristics of the central zone of Portugal. The development of this guide was based on the fuels guide (Cruz, 2005), however is still in the exploration phase and so the values of release potential must be developed later. For each fuel class are presented several factors such as the characteristics of the fuel with release potential, the population’s characteristics and the fire behaver, estimating the influence of these factors on potential spotting in release and transport of burning embers and consequently the ignition of fuel beds.

Because of building become higher and more complicated, people may not know the environment states and have not enough information for evacuation, that cause people lost the prime time of emergency evacuation. In this thesis, we propose a Density Balance Evacuation Guidance base on Crowd Scatter Guidance (DBCS) algorithm for emergency evacuation to make up for fire escape equipment can improve the speed and evacuation effect. The DBCS algorithm has consider the environment states, the people states of mind, the state of evacuation path, and the diffusivity of fire, to calculate the appropriate evacuation path for each user. In the proposed algorithm, people will be divided into different groups and give different evacuation routes for balancing the load of evacuation paths and exits. We also conduct the simulation experiment of the DBCS algorithm in the thesis, the simulation results showed that DBCS algorithm is more effective for distributing the load of evacuation paths, reducing the crowded situation, and has better evacuation performance. Compared with previous methods, DBCS algorithm has reduced at least 51% crowded probability and can improve the evacuation speed by 33%. Moreover, we have implemented an emergency evacuation system what could accomplish in real conditions and combined with theory and real applications as well. In the system, we integrated context awareness, personnel positioning technique, central control, handheld devices, user navigation and DBCS algorithm to construct an emergency evacuation system that can operate in the real life.

The purpose of this study was to discuss crown structure and biomass of mature China-fir (Cunninghamia lanceolata). The study area is location in the central part of Taiwan, at compartment no.111, Pa-Hsien-Sha working circle and Shyr-Wen-Shi demonstration zone. Data of this study were collected from stand and 16 sample trees of a mature China-fir plantation. This study is based on theory way, and use forest measure method and statistics software, to analysis the relationships of DBH and the other attributes, and characteristic of crown form and crown structure, and estimate the of net productivity, and analysis leaf area amount. The analyzed results are summarized as follows. In the vertical distribution of crown, the relationship among crown-length(LC), clear-length(HB) and tree DBH of open-growth tree were found positively linear. LC and HB were increased as DBH increased. The mean crown ratio(CR) about 0.58, which have certain proportionate relationships, and growth condition was very well. The crown form and crown structure of mature China-fir, which the crown form shown cone or cylinder, and the leaf weight can to discriminate upper crown and down crown by maximum leaf density distribution on vertical layer. The maximum leaf density distribution is 1.7~2.0 kg/m on the from top to 3~5 m. The net productivity of China-fir, the net production of stem and branch were increased as DBH increased, the maximum net productivity of aboveground was diameter classⅡ about 1.46 ton/ha/yr. The major dry-matter distributions of China-fir stem increase with DBH, the branch dry-matter increase with height on the vertical distribution, the leaf dry-matter was concentrated in the upper or middle parts of the crown, and it is similar to the broad leaf type dry-matter distribution. The crown leaf area of China-fir individual tree increase with diameter class, so diameter class Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅴ of leaf area were 74.15, 104.13, 133.11, 164.31, 206.34 m2/tree, respectively. And it is estimate China-fir leaf area index about 3.87. The highly positive correlations were found between leaf area and sapwood, accord with the pipe model theory. The pruning operation might be useful maximum leaf density distribution on the vertical distribution of the China-fir plantation, and CR keep to 0.20~0.30 was expediency. The leaf spatial density was diameter class Ⅱ, and it have maximum biomass. The results will provide detailed information for China-fir plantation management.

In a dental CAD/CAM system, when milling the concave area of the inside surface of a tooth crown, the machining direction of the tool has to be adjusted constantly in order to avoid gauging or over-cutting. For some under-cut area, the tool also needs to be tilted to machine the under-cut area, otherwise the crown may not seat properly on the abutment due to interference. The purpose of this research is to establish a new 5-axis tool path generation algorithm. Based on the triangular mesh model, a hybrid C-Space and Centroid method is proposed to quickly search the proper tool axis directions. The establishment of a computer-aided manufacturing (CAM) system for automatic tool-path generation is applied to dental crown machining. The traditional 3-axis machining, when applied to complex surface milling of a dental crown, has never been satisfactory. It cannot produce the desired smooth and gauging free surface. In this thesis, we use the STL format to generate a 5-axis tool-path. First, the orientation of the workpiece will be corrected to reduce tool inclination changes. Secondly, the system generates the tool-path by the Z-Level algorithm. Finally, we use the proposed hybrid C-Space and Centripetal method to determine the tool axis. The integration of the above methods makes the automatic tool-path generation of the crown surface possible, which is very important for the automation of a dental CAD/CAM system.
