Guenoden, Laura. „PM and material decay: analysis of dry depositions on horizontal and vertical surrogate surfaces through a Deposition Box system“. Master's thesis, Alma Mater Studiorum - Università di Bologna, 2017. http://amslaurea.unibo.it/14469/.

Airborne Particulate Matter (PM), can get removed from the atmosphere through wet and dry mechanisms, and physically/chemically interact with materials and induce premature decay. The effect of dry depositions is a complex issue, especially for outdoor materials, because of the difficulties to collect atmospheric deposits repeatable in terms of mass and homogeneously distributed on the entire investigated substrate. In this work, to overcome these problems by eliminating the variability induced by outdoor removal mechanisms (e.g. winds and rainfalls), a new sampling system called ‘Deposition Box’, was used for PM sampling. Four surrogate materials (Cellulose Acetate, Regenerated Cellulose, Cellulose Nitrate and Aluminum) with different surfaces features were exposed in the urban-marine site of Rimini (Italy), in vertical and horizontal orientations. Homogeneous and reproducible PM deposits were obtained and different analytical techniques (IC, AAS, TOC, VP-SEM-EDX, Vis-Spectrophotometry) were employed to characterize their mass, dimension and composition. Results allowed to discriminate the mechanisms responsible of the dry deposition of atmospheric particles on surfaces with different nature and orientation and to determine which chemical species, and in which amount, tend to preferentially deposit on them. This work demonstrated that “Deposition Box” can represent an affordable tool to study dry deposition fluxes on materials and results obtained will be fundamental in order to extend this kind of exposure to actual building and heritage materials, to investigate the PM contribution in their decay.

Der volle Inhalt der QuelleAnnotation:
Initial fire spread is composed of the processes of ignition, flame spread, and burning rate. The effects of a material's thermal characteristics and burning behaviors on flame spread are important. However, many zone and field models of compartment fire can not predict spread on objects accurately enough due to the neglect of these behaviors in their fire growth sub-models. As a result, a model dedicated to the early stage of fire growth is needed to provide the accuracy necessary for competent assessment of the response of safety systems, as well as satisfying the requirement for a comprehensive risk assessment. This study is undertaken to investigate the use of formulations outlined by previous researchers by review of the theory of flame spread models. A computer model is proposed that can determine the impact of the material properties with emphasis on practical engineering analyses. Through this computer program, we can obtain the pyrolysis zone, the flame height, the burnout time, the burnout portion, the mass loss rate, total heat release rate, and mean flame velocity of a material at specific time. The effort in this study has been focused on developing a relatively simple model for fire spread on a vertically oriented material which contains the most common aspect of fire growth theory such as the transit burning rate, material properties, burner affection, flame spread rate and burnout. This study used Vc++ as a program development platform which has an easy to use interface and reasonable execution times. The model is a combination of two sub-models. One is to simulate the flame spread on horizontal surface. The other is to simulate it on a vertical surface. In two sub-models, the spread process model is two-dimensioned yet symmetric. By using empirical physical equations and correlations, this model predicted flame spread by solving a set of closed coupled correlations simultaneously. Each sub-model contains several functions: ignition, mass loss rate calculation, burning area and the surface temperature calculation. The results of this proposed computer model are compared with experimental studies involving a limited number of comparisons of experimental data for early stage vertical flame spread. The model calculations and experimental measurements of the mass loss rate, heat release rate, and radiation flux were found to be in good agreement. Recommendations are made for further development of the more complex initial stage fire growth model.

Der volle Inhalt der QuelleAnnotation:
This Master’s thesis is to delineate a luminaire design which has a flexible functional form, can be controlled by the user, and which creates multidirectional light distribution within an indoor space. A lighting solution with varied light distributions can change a space’s different spatial experiences, granting a flexibility which is controlled by the user to direct light rays into walls, floors, ceilings or to create variations of these. A flexible luminaire in terms of light distribution allows, vertical and horizontal surfaces to be valued equally, because through a minimal intervention it is possible to shift the focus from one surface to another, providing a holistic interplay in space. The participants, who took part in the evaluation program of the final luminaire, freely introduced their possible activities in the predefined dining room, with different lighting proposals according to personal preferences of spatial experience. The designed luminaire was the only accessible tool to influence the space, and they managed to achieve their ideal atmospheres, and experiences, by the process of adjusting the luminaire with controlled light distribution. The varied results of the patterns of brightness and darkness on the vertical and horizontal surfaces in the predefined real space, prove the flexibility of the final design of the luminaire, MM Lamp. The luminaire fulfills the predefined design objectives of being user adjustable as well as creating varied light distribution.

Abstract The main objective of this study is to clarify the current challenges and preconditions relating to product portfolio management (PPM) and widen the PPM framework over horizontal and vertical portfolios, including a related governance model, strategic performance management and the PPM process. This study analyses comprehensively the current PPM literature and the relevant practices of 10 case companies representing business areas such as hardware (HW), software (SW) and Services. This study approaches PPM from a more comprehensive viewpoint as all product life cycle phases and product structure levels are not covered well in this context by the earlier literature. The principal results of this study involve revealing the need for a new PPM governance model including strategic targets, KPIs and the PPM process according to vertical and horizontal portfolios. The created PPM framework clarifies the strategic role of PPM in cross-functional analysis and decision making for commercial and technical portfolios. The role and the impact of strategic PPM have been further enhanced by positioning the PPM process on the level of other business processes. The created PPM framework enhances the collaboration between business and engineering teams. The managerial implications include the potential preconditions of clarifying the dynamic and active role of PPM at the level of other business processes. The findings can aid business managers in understanding PPM as an entity that has a role in managing the entire product portfolio and its renewal based on strategic performance measures over horizontal and vertical portfolios according to cross-functional governance bodies. This highlights the criticality of managing all items both in commercial and technical portfolios. The role of other business processes should be highly operational by executing product development, marketing and sales, delivery and care activities according to PPM decisions. The primary role of PPM should be active management of the entire product portfolio over product life cycle phases and product structure levels, instead of merely focusing on new product development, to ensure product portfolio renewalTiivistelmä Tämä tutkimus selventää tuoteportfolion hallintaan liittyviä edellytyksiä ja haasteita, sekä laajentaa tuoteportfolion hallintamallia, suorituskyvyn johtamista ja prosessia horisontaalisesti ja vertikaalisesti. Tuoteportfolion hallintaa on lähestytty kattavasti analysoimalla nykyistä kirjallisuutta, sekä kymmenen kohdeyrityksen käytänteitä nykytila-analyysin keinoin. Kohdeyritykset edustavat useita liiketoiminta- ja tuotealueita kattaen laitteiston, ohjelmiston ja palvelut. Tämä tutkimus lähestyy tuoteportfolion hallintaa laajemmalta katsantokannalta kuin nykyinen kirjallisuus joka ei kata kaikkia tuotteen elinkaaren vaiheita ja tuoterakennetasoja. Tämän väitöstutkimuksen tärkeimmät tulokset liittyvät uuden tuoteportfolion hallintamallin tarpeellisuuden esille tuomiseen, sisältäen tuoteportfolion strategiset tavoitteet, suorituskykymittarit ja hallintaprosessin perustuen vertikaalisiin ja horisontaalisiin tuoteportfolioihin. Luotu viitekehys selkeyttää tuoteportfolion hallinnan strategista roolia organisaatiorajat ja liiketoimintaprosessit ylittävässä analyysissa ja päätöksenteossa liittyen kaupallisiin ja teknisiin tuoteportfolioihin. Strategisen tuoteportfolion hallinnan roolia ja merkitystä on erityisesti korostettu nostamalla tuoteportfolion hallintaprosessi muiden liiketoimintaprosessien tasolle. Tässä tutkimuksessa luotu tuoteportfolion hallinnan viitekehys vahvistaa yhteistyötä liiketoiminnanjohto- ja insinööritiimien välillä kaikilla organisaatiotasoilla. Työn kontribuutiot yritysjohdolle korostavat tuoteportfolion hallintaprosessin keskitettyä, dynaamista ja aktiivista roolia johtaa yrityksen kaupallisia ja teknisiä nimikkeitä horisontaalisesti ja vertikaalisesti kokonaisuutena perustuen strategisiin suorituskykymittareihin. Tuoteportfolion hallinta yli horisontaalisten ja vertikaalisten portfolioiden mahdollistaa tuoteportfolion uudistumisen yli kaikkien elinkaarivaiheiden ja tuoterakennetasojen. Muiden liiketoimintaprosessien roolin tulisi olla selkeästi operatiivinen toteuttaen tuotekehitykseen, markkinointiin, myyntiin, tilaamiseen, hankintaan, toimittamiseen ja huoltoon liittyviä tehtäviä perustuen strategisiin tuoteportfolion hallinnan tavoitteisiin ja suorituskykymittareihin

Optimization of three-dimensional road alignments is recognized as a nonlinear and nonconvex optimization problem. The development of models that fully optimize a three-dimensional road alignment problem is not yet successful,
because there are many factors involved and complexities in
the geometric specification of the alignment. At present, there are two optimization approaches, the models that simultaneously optimize horizontal
and vertical alignments, and those employing two or more stages of optimization processes.
In this thesis, we develop a novel approach of solving a three dimensional
road alignment problem where the optimal horizontal and vertical alignments are determined simultaneously. We develop the surrogate cost model
that approximate the earthwork cost and the pavement cost. The problem is modelled as a multiobjective optimization where the cost due to the length of the road, and the cost due to the volume of earthwork are found to be conflicting objectives. In order
to study the proposed model, two case studies are tested
and the numerical results are provided. The experimental results indicate
that the problem is nonconvex, and that it is, indeed, a multiobjective optimization problem. Further developments and improvements in the area of cost penalty parameters are recommended for future work.Irving K. Barber School of Arts and Sciences (Okanagan)

Der volle Inhalt der QuelleAnnotation:
Previous studies have demonstrated upward flame spread on vertical surfaces to be one of the most serious fire scenarios due to the concurrent direction of flame propagation and air flow. The unburned zone of the wall ahead of the pyrolysis zone consequently receives more heat from the flame, causing the temperature of the unburned wall to rise quickly and the flame to spread more rapidly. In order to prevent the occurrence of hazardous wall fires, there is a need to select materials which satisfy performance-based regulations. This approach needs information from reliable fire models which simulate accurately the fire behaviour of materials in their end-use configuration. However, none of the existing models are used in this way. This is because of the limitations of the models themselves, in particular the assumptions involved and uncertainties in the empirical correlations used in the models. This study focuses on the early stages of the upward flame spread. An existing model which uses data directly from the Cone Calorimeter test was examined. A non-standard test procedure was developed which gives results capable of giving better predictions from the model. The flame height and heat feedback to the unburned wall were also examined and more information obtained. The flame height was measured from steady burning vertical fuels and from a gas-fuelled panel to examine the commonly accepted relation that the flame height is proportional to the 2/3 rds power of the heat release rate per unit width of the wall fire Q’. In the former experiment, the flame height and Q’ were measured directly in the same experiments, providing data for the early stages of fire spread. In addition, the effect of different geometric configurations was examined. The latter experiment revealed a width effect, questioning the validity of Q’ being the only parameter determining the flame height. Experiments were also carried out to measure the heat transfer to the unburnt material above the pyrolysing zone. A lower value was found to be more representative than the ones used previously. With these modifications, the model was found to give good agreement with experimental measurements of vertical spread on sheets of PMMA. Two additional cases were studied: wall fires influenced by an inert parallel wall and by the proximity of a corner. The measurement of flame height and heat feedback provides data for further investigation and modelling work.

Der volle Inhalt der QuelleAnnotation:
Inspired by some newly emerged topics from the real world, this thesis comprises of four essays that study firms’ strategic incentives, as well as the vertical and horizontal agreements between firms. The first essay assesses theoretically firms’ incentives to engage in quality proliferation. We show that it is possible for vertical proliferation to be completely undesirable in the absence of entry threats, therefore proliferation of any level might be anticompetitive. Nevertheless, when proliferation is optimally conducted, it always benefits consumers. The second and third essays focus on vertical contracts between successive stages of production. The second essay places the controversial agency model involved in the e-book case in the context of antitrust treatment to vertical restraints, and examines its effects on competition and welfare relative to the wholesale model. The third essay goes beyond and develops a framework allowing us to clarify the ceteris paribus effects of changing each of the two key elements written in a vertical contract: decision roles and forms of the transfer payment. Based on this framework, we show that it is meaningful to distinguish between classic RRM, by which a manufacturer sets the transfer payment as well as the retail price, and agency RPM, by which a retailer is able to set the transfer payment before a manufacturer set the retail price. The final essay focuses on horizontal cartel agreements and experimentally investigates the effects of endogenous enforcement on cartel prices. We highlight the strategic uncertainty in cartel coordination as a channel of composition deterrence, as well as the potential trade-off between frequency and composition deterrence.

Augmented Reality is commonly used for entertainment purposes on today’s smartphones. We intend to aid the evolution of Augmented Reality as a tool as opposed to a toy. With the use of Apple’s ARKit 1.5 release, which features vertical surface recognition, we implement and evaluate a solution to a target problem which aims to contribute to the knowledge of Augmented Reality’s strength and weaknesses. The implementation allows an iPhone user to measure surface areas by placing anchors to mark an area to be measured. We find that our Augmented Reality tool does not provide the same precision as manual measurements but is still reasonably within boundaries if an estimation is acceptable.

An experimental apparatus was designed and constructed for the study of laminar mixed convection heat transfer in vertical, horizontal and inclined tubes. The working fluid was distilled water, with bulk temperatures in the range of 8$ sp circ$C to 31$ sp circ$C.An innovative design allows, for the first time, flow visualization over the entire heated portion of the test section. The key element of this design is a thin, electrically conductive gold-film heater suitably attached to the outside surface of a plexiglas pipe: the gold film is approximately 80% transparent to electromagnetic radiation in the visible wavelength band. This test section was mounted inside a transparent vacuum chamber to insulate it from the environment. A dye injection technique was used to visualize the mixed-convection flow patterns. The apparatus was also designed and instrumented to allow the measurement of both circumferential and axial temperature variations over the heated tube.
The flow-visualization results revealed the following: (i) a steady recirculating flow pattern, followed by laminar flow instability in vertical tubes; (ii) steady spiralling flow patterns in inclined and horizontal tubes, that confirmed earlier numerical predictions. The temperature results agreed qualitatively with earlier published experimental and numerical data. Local and overall Nusselt numbers can be calculated using the data presented, but this is not within the scope of this thesis.

The roof is man's basic shelter against the elements. The form of the roof itself affects the image of a building. The problem of shelter has been approached in different ways by different cultures. A wide range of forces such as climate, technology, available resources and social, personal and stylistic influences give form to the roof. These forces are particular in both place and time. As a framework for investigation that can apply to all roofs, this thesis looks specifically at roof forms as a response to the force of gravity, approached in terms of a dialogue between horizontal and vertical. Assuming the ground to be horizontal and the building essentially vertical, the building is seen as aspiring to some connection with the vault of the sky. The roof is explored as the meeting of building and sky -- a transition zone between shelter and openness. The forms, materials and spaces that work to resolve that connection as well as the associations and meanings they have for man are explored. The purpose is to better understand the fundamental forces that affect the form of roofs and people's perceptions of them.

wide range of pathogens are transmitted by a combination of horizontal and vertical transmission; among these are microsporodians, helminths, bacteria and viruses of plants and animals, including important human pathogens such as HIV, HTLV-1, cytomegalovirus, several hepatitis viruses and herpes simplex [Proc. R. Soc. Lond. B 260: 321-327]. In this work, the vertical parasite spreading from parent to offspring and horizontal transmission through infection in a population of moving individuals are discussed using a probabilistic cellular automata implemented on a square lattice. In our model, we generalize the automata proposed in [J. Phys. A : Math. Gen. 27: 1585-1597] to include the vertical transmission. The local rule consists of two subrules: the first one, applied synchronously, models infection, birth and death processes; the second, applied sequentially, describes the motion of individuals. In this model, endemic states may occur (susceptible and infected individuals coexisting) or a disease-free state (without infected). It is worth mentionins that a state in which the entire population becomes infective is possible in the case of perfect vertical transmission, i.e. infected parents give birth only to infected offspring. Moreover, the stability of these states may be analised using a mean-field approximation or grafically verified from the numerical simulations.
Uma ampla faixa de patógenos são propagados por uma combinação de transmissão horizontal e vertical, dentre os quais podemos destacar: microesporídeos, helmintos, bactérias, fungos e vírus de plantas e animais, incluindo importantes microorganismos parasitas de humanos como o HIV, HTLV-1, cytomegalovírus, vários tipos de hepatite e herpes simples [Proc. R. Soc. Lond. B 260: 321-327 (1995)]. Neste trabalho, a transmissão vertical (infecção do genitor para os filhos) e a transmissão horizontal (infecção por contágio) numa população de indivíduos em movimento são discutidos usando um autômato celular probabilístico implementado numa rede quadrada. Em tal modelo, generalizamos o autômato proposto em [J. Phys. A : Math. Gen. 27: 1585-1597 (1994)] para incluir a transmissão vertical. A regra local consiste de duas subregras: a primeira modela de maneira sincronizada os nascimentos, as mortes e as infecções; já a segunda, aplicada sequencialmente, descreve o movimento dos indivíduos. Neste modelo é possível um estado endêmico (suscetíveis coexistindo com infectados) ou um estado livre de doenças (sem infectados). Salienta-se que um estado em que toda a população torna-se infectada é possível no caso de transmissão vertical perfeita, i.e. pais infectados possuem apenas descendentes infectados.

…the future is that; I think we have hit rock bottom and that the only way we can go now is not down but up. I have hope. I have told Malawians that we need to look into the future with hope and I know that we shall be fine. What I am implying here is that ultimately what is going to save democracy in Malawi is the willingness by Malawians to protect themselves and preserve the freedoms and rights which they have…, (President, Joyce Banda, 2011). The thesis of this study is that the Malawi Parliament ought to be the hub of vertical and horizontal accountability in legislation, representation and oversight roles. Salih, (2005, p.3) states that parliaments are caught between fulfilling the governance role and acting as part of government. Therefore, in order to effectively fulfil this objective, parliament must be supported, (Ma Ngok, in Siu-Kai, 2002). However, the study notes that the Malawi Parliament has a high executive influence; no policy making power with minimal legislative viscosity, (Norton, 2005, 1990; Polsby, 1975; Mezey, 1979 and Blondel, 1973). Consequently, it is argued with empirical data that since the 1994 multiparty election, parliament has not been effective in its vertical and horizontal accountability roles, (Lindberg, 2009). In the horizontal accountability, parliament plays an inter-governmental role of the executive oversight as well as that of checks and balance, (Stapenhurst and O’Brien, 2011, p. 3). In the vertical, parliament is held accountable through its elected members by its voters, stakeholders and the civil society, (Chirwa and Nijzink, 2012, p.6). It is argued that when voters (principals) delegate their decision-making power to parliament (agent), the principal must have mechanisms in place of holding the agent(s) accountable for their actions or lack of it and if necessary, impose sanctions or remove the agent from power, (Strom, 1999, pp. 7, 8). In every developed democracy, government policies and services are demand driven; sanctioned, monitored and evaluated by the legislature (Lupia and McCubbins, 1999, p. 4). Using empirical data, the study observed that although the Malawi Parliament has made significant reforms towards regaining its independence and autonomy from the executive, it still continues to be seen as a legitimatisation and sometimes rubberstamping institution, (Nyamongo, 2010; Chinsinga, 2007; Patel, 2007). The contributory factors were both intrinsic and extrinsic such as lack of institutional capacity as well as political will by the executive to support a greater parliamentary autonomy. Thus, the study recommends that the Malawi Parliament institutes a human resource development programme in order to improve the technical capacity of legislative support staff as well as MPs; increase funding and strengthen parliamentary committee system for higher scrutiny as well as a wider stakeholder consultation at every stage of the legislative process; The study also recommends that appointments of directors in auxiliary governance agencies such as the Anti-Corruption Bureau, the Electoral Commission of Malawi, and the Human Rights Commission shift from the presidency to parliament. It is the assumption of this study that increasing parliamentary oversight potential promotes democracy and good governance, (Pelizzo and Stapenhurst, 2007, p.13).

Mestrado em FinançasO presente projecto consiste numa avaliação da Corticeira Amorim SGPS SA. Este contém uma análise financeira detalhada da empresa, focando-se ainda na indústria e nas oportunidades de M&A para a Corticeira Amorim e os seus concorrentes. Este relatório segue o formato recomendado pelo CFA Institute e considera apenas informação pública disponibilizada até 15 de Janeiro de 2019. A empresa em questão foi selecionada pela CFA Society Portugal no âmbito do CFA Research Challenge 2019. A Corticeira Amorim, uma das maiores empresas em Portugal, é a maior produtora de rolhas de cortiça a nível mundial. A empresa domina a indústria com uma quota de mercado de 44%. Da nossa análise resulta uma recomendação de COMPRA com um preço-alvo de €10.9/ação, correspondente a um potencial de valorização de +21% face à cotação de 31 de Dezembro de 2018. Para avaliar a Corticeira Amorim foi utilizado o método de Fluxos de Caixa Descontados (DCF), uma vez que se trata de uma empresa matura com fluxos de caixa estáveis. O principal modelo utilizado foi o Free Cashflow to the Firm (FCFF). Como complemento à nossa análise, foram ainda utilizados os modelos Free Cash Flow to Equity (FCFE) e Dividend Discount Model (DDM). Os principais riscos para a nossa recomendação são relativos às possíveis mudanças no consumo de vinho e à não existência de cortiça suficiente para os produtores. Adicionalmente, foi analisado o risco que advém de um cenário de maior consolidação do mercado.
This project consists of an Equity Research Report on Corticeira Amorim SGPS SA. It contains extensive financial analysis on the company with a special emphasis on the industry's landscape and the M&A opportunities available to the company and its competitors. This report follows the format recommended by the CFA Institute and is based on the publicly available information until the 15th of January 2019. The company was chosen by the CFA society Portugal for the CFA Research Challenge 2019. Corticeira Amorim, one of the biggest Portuguese companies, is the world's largest cork stoppers producer. It dominates the market with 44% of the global market share. The company is diversified within the cork industry as, besides stoppers, it produces the floor and wall coverings, insulation and composites. We issue a buy recommendation with the price target of €10.9 and upside potential of +21% from December 31st, 2018 closing price. To reach our price target we used the Discounted Cash Flow (DCF) approach, as it is a mature company with a stable cash flow stream. As the main model, we used the Free Cash Flow to Firm (FCFF). Additionally, to complement our analysis we used the Free Cash Flow to Equity (FCFE) and the Dividend Discount Model (DDM). The main risks to our recommendation are the change in wine consumption and the availability of cork. In addition, we extensively researched the risk that could come from further consolidation in the market and we offered our analysis for that scenario.

In three studies, we characterize the effect of a nearby distractor on vertical, horizontal and oblique saccadic curvature under normal saccade preparation times. In Experiments 1 and 2, participants made saccades to targets in the presence or absence of a nearby distractor. Consistent with previous findings, longer-latency vertical saccades showed greater curvature away from a distractor than did oblique or horizontal saccades. At short latencies, vertical saccades showed greater curvature towards the distractor. We propose that vertical saccades may be prone to greater distractor interference due to the superior colliculus, a midbrain region implicated in attentional and saccadic shifts, under-representing vertical target objects, which results in a relative over-representation of non-vertical distractor objects. In Experiment 3, we tested this hypothesis by having participants make saccades to vertical or horizontal targets in the presence or absence of bright or dim distractors. We reasoned that weaker representations for vertical targets would allow for greater interference from nearby distractors, which would be especially pronounced when distractors are highly salient. Consistent with this prediction, we found that only the trajectory of vertical saccades was modulated by distractor luminance.

This thesis attempts to determine if food-producing plant growth can be incorporated within a building envelope to create an ideal plant growth environment while simultaneously enhancing the thermal properties of the building envelope. A window system was designed as a means of bringing food production into the built environment in an easily accessible fashion from the interior of a high-rise apartment complex. The Ya-Po-Ah Terrace in Eugene, Oregon, was chosen as a case study site for research on how a window could promote health, provide nutrition, and enhance the thermal comfort of the inhabitants. The design of the window unit is founded in precedent research on methods of plant growth in urban environments and systems for growing food in small and efficient ways. The design found that it is possible to create an ideal plant growth environment within a building assembly for use as a food production method for building inhabitants.

Peer-learning enhances the learning experience of students, but little research in this area has studied medical students developing their clinical physical examination skills. This thesis describes two peer-learning processes to aid this skill development: peer???learning from advanced beginners to novices (vertical); and peer-to-peer learning (horizontal). The hypothesis was that the process would be effective and acceptable to tutors and tutees. Vertical Peer Teaching: After a successful pilot scheme using junior doctors to tutor medical students, senior medical students were engaged as tutors as the junior doctors were too busy. Following instruction in tutoring and defining teaching topics, they taught a group of junior students. Evaluation of both groups was by summative clinical examination scores, by interviews and questionnaires. Scores were compared with non-participating control subjects. Tutors showed a significantly superior examination performance compared with the control group. Tutees showed a non-significant improvement. Tutors considered their skills had improved, with increased confidence in both performance and teaching, particularly in the communication and metacognitive domains. Tutees indicated the process to be very useful, with increased opportunity for feedback and questioning. There was little evidence of a reduction in the barriers between the years, perhaps because the student tutors were viewed in the traditional role of 'experts' . Horizontal Peer Teaching: Same-level dyads using a videotaped examination skill and script were assessed by summative examination and subjectively. These skills showed a significant improvement when compared to a control group. Despite this effect and many positive aspects reported, there were some concerns with the process. Students felt that a videotape and a peer instead of an ???expert??? was not as good as a traditional tutorial. In conclusion, the peer-learning was successful in several domains. Vertical peer-learning was accepted by both tutors and tutees, and horizontal-peer learning had a positive influence upon examination results. Vertical peer-learning appears to conform to students??? expectations of the inequality between beginners and tutors who are advanced beginners or experts, while horizontal peer-learning is more challenging, even though it is effective. The latter may need careful introduction for the process to be acceptable to students.

Der volle Inhalt der QuelleAnnotation:
Hydraulic conductivity is a measurement of the ease of movement of a fluid through a medium and is therefore a key parameter in the design of landfill leachate management systems. Hydraulic conductivity of landfilled wastes may be affected by several factors such as overburden stress from the weight of overlying waste, water content, the type, age and pre-processing of the waste, and the presence of landfill gas. A further factor that may affect leachate movement through wastes is the predominantly horizontal orientated structure of compacted wastes. This anisotropic structure may result in hydraulic conductivity in the horizontal direction being greater than that in the vertical direction. However existing research has been effectively limited to evaluating hydraulic conductivity in a single plane and so the presence of anisotropic flow in waste remains unproven. Consequently, modelling of leachate and contaminant movement in landfills may be compromised by the use of isotropic, or assumed anisotropic, hydraulic conductivity values. The object of this research has been to assess for the first time the inherent anisotropy of two different waste samples by measuring and comparing the vertical and horizontal hydraulic conductivities over a range of stresses typical of landfill conditions. In this thesis, factors affecting the measurement of hydraulic conductivity of wastes are discussed, and details of the samples tested and test methodology are given. The results of the tests are shown and alternative test methods are discussed. The effects of gas accumulation and pore water pressure on waste hydraulic conductivity encountered during testing are also reported as further research has developed from this important finding.

Projeto de Pós-Graduação/Dissertação apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Medicina DentáriaA reabilitação oral com implantes é um procedimento que requer volume ósseo suficiente da crista óssea alveolar para uma correcta colocação dos implantes, promovendo uma restauração funcional e estética. Quando se verifica insuficiente volume ósseo, são necessários procedimentos de aumento ósseo para obter largura e altura óssea suficiente para ancoragem dos implantes. A regeneração óssea guiada é um método de aumento ósseo que consiste na utilização de membranas que servem de barreiras, impedindo a migração de células epiteliais para o interior dos defeitos ósseos, permitindo que apenas células formadoras de osso ocupem o local do defeito. O objectivo deste trabalho está direccionado para a análise do sucesso e previsibilidade clínica desta técnica de aumento ósseo e qual o sucesso de implantes colocados em osso regenerado, abordando vários tipos de membranas e enxertos ósseos e combinações entre eles. Este trabalho consiste numa revisão da literatura, baseando-se numa pesquisa de artigos nas bases de dados on-line através da utilização criteriosa de palavras-chave e recorrendo também à consulta de livros. A regeneração óssea guiada manifesta comprovado sucesso e previsibilidade no aumento ósseo e os implantes colocados em osso regenerado demonstram sucesso a longo-prazo. Oral rehabilitation with implants is a procedure that requires sufficient bone volume of alveolar crest for proper implant placement, providing a functional and aesthetic restoration. When there is insufficient bone volume, bone augmentation procedures are required for obtaining enough bone height and width for implant anchorage. The guided bone regeneration is a method of increasing bone involving the use of membranes which serve as barriers, preventing the migration of epithelial cells into the bone defect, allowing only bone-forming cells to occupy the site of the defect. The aim of this work is directed to the analysis of clinical success and predictability of this technique for bone augmentation, and what the success of implants placed in regenerated bone is, addressing various types of membranes and bone grafts and their combinations. This work consists of a literature review, based on a survey of articles on the online databases, through the judicious use of keywords and the consultation of books. The guided bone regeneration manifested proven success and predictability in bone augmentation and implants placed in regenerated bone demonstrate long-term success.

La chaine d’approvisionnement énergétique a fortement évolué aux cours des 20 dernières années. La libéralisation des marchés de l’électricité et les nouvelles technologies ont fortement influencé la manière d’envisager la production et la transmission d’électricité. Les modèles mathématiques classiques utilisés dans les problèmes lié à l’énergie ont besoin d’être revus pour intégrer les contraintes pratiques modernes.Un problème classique pour un Compagnie Génératrice (CG) est le problème de Unit Commitment (UC) qui consiste à établir un plan de production pour une demande en électricité connue. Lorsque ce problème fut considéré, le prix de l’électricité et la demande étaient relativement simple à estimer comme une seule CG nationale avait le monopole du marché. Ce problème a été étudié de manière extensive en utilisant de la Programmation Mathématique (PM). Aujourd’hui, le prix de l’électricité est relativement volatile à cause de l’introduction de marchés dérégulés et la demande du marché est répartie entre plusieurs CGs en compétition sur divers marchés. Une CG ne peut se limiter à considérer un problème de UC seul pour envisager sa production. Il y a un besoin d’intégrer les incertitudes liées au marché de l’électricité et aux quantités à produire aux modèles utilisés pour qu’une CG puisse établir un plan de production rentable.La technologie a aussi permis d’envisager de nouveaux concept tel que les Micro-Grilles (MGs). Une MG est composée d’un ensemble de consommateurs reliés à travers un réseau de transmission, possédant des générateurs d’électricité et optimisant leur consommation interne. Ce concept est possible grâce à l’utilisation croissante d’énergies renouvelables locales ainsi que l’utilisant croissante d’appareils interconnectés. Cependant, étant donné que les énergies renouvelables ont un faible rendement, sont intermittentes et que les appareils de stockage d’énergie sont encore peu efficaces, les MGs ne peuvent pas envisager d’être pleinement autonome en électricité. Il y a donc une nécessité d’avoir un fournisseur d’électricité externe pour avoir suffisamment d’électricité disponible à tout moment. Une CG jouant le rôle de fournisseur auprès d’une MG fait face énormément d’incertitude concernant la demande à cause de la gestion interne de la MG sur laquelle elle n’a pas de contrôle.Dans cette thèse, des problèmes d’optimisation intégrant de nouvelles contraintes modernes liés à l’approvisionnement énergétique sont étudiés via la PM. Plusieurs problèmes considèrant des interactions entre plusieurs acteurs sont modélisés via des formulations bi-niveau. Nous illustrons comment les difficultés liées aux contraintes modernes peuvent être exploitées pour obtenir des propriétés permettant de reformuler les problèmes étudiés en formulation linéaire en nombre entiers. Des heuristiques performantes sont obtenus à partir des formulations exactes dont certaines sont applicables à des problèmes plus généraux. Une analyse extensive de la performance des méthodes de résolution ainsi que de l’influence des contraintes modernes sont présentées dans diverses expériences numériques.Doctorat en Sciences

While numerous studies have been conducted on using the one-dimensional, two-fluid model to simulate a range of flow regimes in horizontal and nearly horizontal pipes, no work has been conducted thus far on using the model to simulate intermittent flow in vertical pipes, specifically in the slug flow regime where large gas bubbles are separated by rising liquid slugs. This thesis presents the development of the model to accurately simulate this flow regime. For the first time, it has been shown that the model can capture the underlying physics behind slug generation in vertical flow: that of a falling liquid film leading to a bridging of the pipe, thereby resulting in the formation of slugs. Closure relations for the interfacial shear force are proposed, tested and developed, where it was found that the choice of model used in the flow development region has a significant effect on the flow downstream. A new correlation has been developed that is able to accurately reproduce results and trends seen experimentally. The effects of the viscous diffusion term, a pressure loss model at the slug front and the surface tension term, all previously introduced into the model, were tested for the vertical flow cases. The effects of mesh size and the influence of the inlet boundary conditions on the characteristics of the generated slugs were also investigated. As well as the vertical slug flow work, the thesis also presents results obtained in testing the models capabilities to simulate two other effects found in two-phase flows in pipes. The first is the hysteresis phenomena found in horizontal pipes, where the point of transition from stratified flow to slug flow and vice versa is found to shift depending on the starting flow regime. The second is terrain-induced slugging, where bends in the pipe can cause a localised build-up of liquid, causing undesired fluctuations in flow rates and pressures at the pipe outlet.

La communication est un élément incontournable dans les organisations lors des périodes de changement, qui sont elles-mêmes inhérentes à toute organisation. Il existe une variété de modes de communication d'un changement lors de son implantation. L'objectif de cette recherche consiste à explorer les liens entre des modes de communication et des caractéristiques culturelles des destinataires d'un changement. Cent-vingt et un étudiants d'origines culturelles diverses et habitant les résidences d'une université québécoise ont servi d'échantillon pour l'étude d'un changement devant y être implanté. Les variables culturelles suivantes ont été mesurées chez ces participants : l'individualisme vertical, l'individualisme horizontal, le collectivisme vertical et le collectivisme horizontal. Trois modes de communication matérialisés en trois vignettes annonçant un changement (le mode monologique, le mode dialogique, et le mode séducteur) ont été utilisés auprès de trois groupes distincts de participants dont les préoccupations face au changement ainsi annoncé ont ensuite été mesurées. Des analyses de régressions multiples n'ont pas permis de confirmer les hypothèses, à savoir que les niveaux de l'ensemble des préoccupations seraient plus bas lors d'une communication monologique pour les personnes ayant un haut niveau d'individualisme vertical, lors d'une communication dialogique pour celles qui ont un haut niveau d'individualisme horizontal ainsi que lors d'une communication dite séductrice pour celles qui ont un haut niveau de collectivisme vertical. Par contre, des analyses exploratoires ont montré qu'un haut niveau d'individualisme horizontal pourrait conduire à avoir davantage de préoccupations liées à la résistance au changement lors d'une communication dialogique. Dans le même sens, de hauts niveaux de collectivisme vertical ou d'individualisme vertical amèneraient l'expression d'un plus grand nombre de préoccupations liées au soutien au changement lors de communications monologiques ou séductrices. Ces données amènent à supposer que les préoccupations, voire la résistance au changement, seraient maximisées par une communication adéquate et qu'elles seraient favorables au changement. Les modes de communication adéquats et les réactions des destinataires d'un changement ne seraient pas les mêmes dans toutes les cultures.

In order to better quantify the continuous net ecosystem exchange (NEE) at the farm scale, a 24 m high transportable tower-based eddy covariance and profiling system was tested during three field campaigns during the summer and autumn of 2006. The profile measurement system, equipped with a low-cost closed-path infrared gas analyser (LI-840) was designed to measure the carbon dioxide (CO2) storage especially during weak mixing periods under stable conditions. A tethered blimp-based measurement system for the nocturnal boundary layer (NBL) budget technique was deployed on several calm nights to compare with the concentrations and fluxes determined with the profiling system. The profiling system was also installed to determine horizontal and vertical advection. The two-dimensional horizontal positioning of the profile inlets allowed an examination of the CO2 advective gradient in relation to the wind direction. A near-source advection analysis provided parameters for further adjustments of the NEE at the actual farmland.

For simulations of future climate to be reliable, clouds must be represented as realistically as possible. However, most radiation schemes in climate models currently make a number of simplifications when accounting for clouds, one of the most important being the removal of horizontal inhomogeneity (the "plane-parallel" approximation). This has significant effects on the interactions of the clouds with radiation. In this thesis, a new scheme called "Tripleclouds" is presented that attempts to account for the neglected inhomogeneity by using two regions of cloud in each vertical layer of the model as opposed to one. One of these regions represent the optically thinner cloud in the layer, and the other represents the optically thicker cloud. Furthermore, the scheme uses a ''decorrelation'' overlap method that improves on more conventional "maximum-random'' overlap by overlapping vertically continuous cloud with increasing randomness for pairs of layers with larger vertical separation.

Neste trabalho realizamos um estudo de um sistema dinâmico não ideal, constituído por um pêndulo acoplado a um bloco e que oscilam verticalmente. A oscilação é devida a rotação de uma massa desbalanceada e acionada por um motor DC, cuja fonte de energia é limitada. Consideramos situações em que as freqüências do bloco e do pêndulo estão em ressonâncias internas 1:1, 1:2 e 2:1, e analisamos o comportamento do sistema bloco- motor-pêndulo através de simulações numéricas. Uma análise similar e levada a efeito, no caso em que o sistema dinâmico é dotado de uma excitação de suporte ideal horizontal do tipo F cos wt.
In this work we studied a nonideal dynamical system which is constituted by a pendulum connected to a block, and that oscillates vertically. The oscillation is due to the rotation of a unbalanced mass moved by DC motor with limited power supply. We consider situations where the frequencies of the block and the pendulum are in 1:1, 1:2 and 2:1 internal resonances, and we analyse the behavior of the block - motor - pendulum system through numerical simulations. A similar analysis is performed in the case where the dynamical system has a periodic horizontal oscillation of type F cos wt.

Resumo: Neste trabalho realizamos um estudo de um sistema dinâmico não ideal, constituído por um pêndulo acoplado a um bloco e que oscilam verticalmente. A oscilação é devida a rotação de uma massa desbalanceada e acionada por um motor DC, cuja fonte de energia é limitada. Consideramos situações em que as freqüências do bloco e do pêndulo estão em ressonâncias internas 1:1, 1:2 e 2:1, e analisamos o comportamento do sistema bloco- motor-pêndulo através de simulações numéricas. Uma análise similar e levada a efeito, no caso em que o sistema dinâmico é dotado de uma excitação de suporte ideal horizontal do tipo F cos wt.
Abstract: In this work we studied a nonideal dynamical system which is constituted by a pendulum connected to a block, and that oscillates vertically. The oscillation is due to the rotation of a unbalanced mass moved by DC motor with limited power supply. We consider situations where the frequencies of the block and the pendulum are in 1:1, 1:2 and 2:1 internal resonances, and we analyse the behavior of the block - motor - pendulum system through numerical simulations. A similar analysis is performed in the case where the dynamical system has a periodic horizontal oscillation of type F cos wt.

This document presents the laboratory measurements and time and frequency domain simulations and calculations regarding the high loss horizontal and vertical transmission lines aiming at improve the knowledge of their performance and well understand the electromagnetic interaction between the lightning channel and the electrical facilities. Impulsive and harmonic 5 MHz to 100 MHz signal generators, were used for the high losses transmission lines excitation. The lines were mounted with series resistors. The laboratory tests were done in the Extra High Voltage Laboratory of the Federal University of Minas Gerais, in the Antenna Laboratory of the Catholic University of Minas Gerais, and in FIAT Shielded Anechoic Electromagnetic Chamber in Betim, Minas Gerais. For the measurements, digital osciloscopes and network analyser were used. The softwares 'Orcad' and 'Mathcad' with its Fast Fourrier Transform and the Inverse Fourrier Transform functions were used respectively for time and frequency domains simulations, The experimental results were compared with the calculations, allowing the proposition of suitable models for horizontal and vertical high losses transmission lines, including impulsive and harmonics current distribution and propagation parameters.O presente trabalho apresenta os resultados de experimentos em laboratório e de avaliações nos domínios do tempo e da frequência, elaborados no sentido de melhor compreendermos os desempenhos eletromagnéticos das linhas de transmissão horizontais e verticais de perdas elevadas, e com isto, agregarmos conhecimento sobre os processos de acoplamento entre o canal da descarga atmosférica e as instalações elétricas terrestres. Foram utilizados, nos experimentos práticos, geradores de sinais impulsivos, geradores de sinais harmônicos de freqüências compreendidas entre 5 MHz a 100 MHz, excitando linhas de transmissão horizontais e verticais com altas perdas, sendo estas construídas com associação de resistores em série. Os testes práticos foram realizados nas dependências do Laboratório de Extra Alta Tensão da UFMG, no Laboratório de Antenas da PUC-MINAS, Campus do Coração Eucarístico e na Câmara Blindada Anecóica Eletromagnética da FIAT Automóveis em Betim. Para a obtenção das medidas laboratoriais foram utilizados osciloscópios digitais e analisador de rede - 'Network Analyzer'. Para os cálculos e avaliações no domínio do tempo foi utilizado o software 'ORCAD' e, no domínio da freqüência, as ferramentas Transformadas Direta e Inversa de Fourrier, através do software 'Mathcad', para a operacionalização das mudanças de domínios. Os resultados práticos e teóricos obtidos foram então confrontados, permitindo análises e conclusões sobre o desempenho das linhas de transmissão horizontais e verticais de altas perdas, incluindo suas distribuições de correntes elétricas impulsivas e harmônicas e seus parâmetros de propagação.
