description: The basic principle of ‘3D Printing’ is the layer wise production of real parts from virtual data – be it with laser, with power glue, electron beam or UV light processing (Hopkinson, Hague, & Dickens, 2006). The professional application of ‘3D Printing’ is ‘Additive Manufacturing’ (AM) and this opens a fascinating new world of engineering. It offers a selection of reliable building construction materials – done in concrete, aluminium, steel, high performance plastics or glass. (Woodcock, 2011) No matter what applications can be found: to ‘design for function’ rather to ‘design for production’ turns our way of engineering of the last century upside down. As a result, AM opens the outlook to applications in our (built) future in combination with the available technologies of today. (Strauß, 2013) The tool-less production with AM allows for new shapes and functional parts in small batch sizes – down to batch size one. The parts performance can be re-interpreted based on the demands within the system, not based on the limitations of conventional manufacturing. AM offers new ways of materializing the physical part around its function. Advancements can for example be achieved in the semi-finished goods: fittings with less, but higher integrated parts could offer a better performance with lower material consumption. Solving the most critical part of a free-form structure and allowing for a smart combination with the approved standards has a great potential, as well. It leads toward customized and enhanced performance. This paper discusses the possible changes and influences, those emerging technologies have on the development of building envelopes. To achieve today’s demands of future envelopes, we have to find new solutions - Additive Manufacturing is one possible way to do so.

In a previous study, we considered the black hole with the vanishing cosmological constant in this theory and constructed the hairy black hole solution with the negative $α$. In this study, we present black hole solutions numerically with various physical properties in anti-de Sitter spacetime. We describe the procedure for constructing the black hole solutions in detail.

MDA5 and a type 1 interferon signature in the development of type 1 diabetes
Creators: name: Lincez, Pamela Joan
Publisher: name: University of British Columbia
Year: 2015

description: Type 1 diabetes (T1D) is a debilitating disease involving the autoimmune destruction of insulin-producing pancreatic β-cells. The personal and economic burden of this disease is enormous, therefore simpler and more cost effective therapeutic approaches than those currently available must be explored. In children at risk for T1D, a unique type 1 interferon (IFN-I) transcriptional signature precedes islet autoimmunity. Recent onset of T1D strongly associates with infection by RNA viruses like coxsackievirus that induce IFN-I. Importantly, genetic variants in the T1D risk locus IFIH1 are linked to protection from T1D and result in reduced expression of the RNA virus sensor melanoma differentiation-associated protein 5 (MDA5), which is also a critical component in establishing the IFN-I signature. In chapter 2 we describe a novel model where we have translated the reduced MDA5 expression phenotype observed in patients onto the non-obese diabetic (NOD) mouse and established its importance in T1D. We describe the first observations that a reduction in MDA5 in the NOD mouse protects from spontaneous and coxsackievirus B4 (CB4)-induced T1D. We also establish the importance of a specific IFN-I signature in the development of T1D as a result of reduced (not eliminated) MDA5 sensing of CB4 that allows for regulatory T cells (Tregs) at the site of autoimmunity and protects from CB4 induced T1D. In chapter 3 we show that this unique IFN-I signature is limited to MDA5 and disease pathogenesis is linked to the specific IFN-I response induced by the virus as a strain of CB3 failed to modify the IFN-I signature associated with disease. Further RNA sequencing discussed in Chapter 4 demonstrates unique tissue-specific differential gene profiles associated with a reduction in MDA5 following CB4 infection. Our results support our hypothesis that there is a direct correlation between the IFN-I signature induced following environmental challenge with the induction of a strong effector T cell and a matched Treg response. This work demonstrates the essential role of MDA5 signaling in regulating the IFN-I signature, implicates MDA5 in T1D susceptibility and in protection against IFN-I and T1D-inducing agents like CB4 and suggests restricting MDA5 function as a potential T1D therapeutic.

description: This paper deals with the greening of claddings and the cooling of buildings from the perspective of a bionic scientist or an industrial designer. Reflections on a new building cover shall early enough show an approach to the containment of future problems in the often predicted ‘urban future’. The development of a concept for a greened cooling cladding happens through the transition of bionic-mathematical principles, which have been considered only a little here so far. The paper begins with a summary of the public debate about the topics urbanization and climate change. The section 'greening of claddings' shall illustrate a smarter, future-orientated idea for the building sector. The section of architectural bionics shows the potentials of nature’s principles of construction, originating millions of years ago, and it analyses relevant bionic principles in full detail. To conclude, the author’s iterative concept development for a bionically-mathematically inspired, greened cooling cladding is explained and the obtained findings are discussed. In addition, further development potentials are considered.

description: Chaos synchronization in a ring of diffusively coupled nonlinear oscillators driven by an external identical oscillator is studied. Based on numerical simulations we show that by introducing additional couplings at $(mN_c+1)$-th oscillators in the ring, where $m$ is an integer and $N_c$ is the maximum number of synchronized oscillators in the ring with a single coupling, the maximum number of oscillators that can be synchronized can be increased considerably beyond the limit restricted by size instability. We also demonstrate that there exists an exponential relation between the number of oscillators that can support stable synchronization in the ring with the external drive and the critical coupling strength $ε_c$ with a scaling exponent $γ$. The critical coupling strength is calculated by numerically estimating the synchronization error and is also confirmed from the conditional Lyapunov exponents (CLEs) of the coupled systems. We find that the same scaling relation exists for $m$ couplings between the drive and the ring. Further, we have examined the robustness of the synchronous states against Gaussian white noise and found that the synchronization error exhibits a power-law decay as a function of the noise intensity indicating the existence of both noise-enhanced and noise-induced synchronizations depending on the value of the coupling strength $ε$. In addition, we have found that $ε_c$ shows an exponential decay as a function of the number of additional couplings. These results are demonstrated using the paradigmatic models of Rössler and Lorenz oscillators.

Increased Thermal Load in Insulated Glass Units

Publisher: name: Journal of Facade Design and Engineering
Year: 2016

description: The oil crises of the 1970s increased the awareness of energy efficiency. Over the past forty years, single- and double-glazed windows have evolved into a range of modern insulating glass solutions for windows and facades. In the mid-1990s the climatic loading of double-glazed units (DGUs) was investigated and design rules were developed for use in practice. Even though those rules were at the time developed for DGUs, they have recently also been used for the design of modern triple-glazed units (TGUs) and multilayer facade systems. So far, no research has posed the question whether this design process, and in particular the temperature differences that have been determined for DGUs, can be applied to other systems. It is therefore the aim of this paper to determine the governing temperatures in insulated glass units (IGUs) under modern boundary conditions. To do this, the thermal behavior of TGUs, multilayer facade systems and solar shading is investigated in detail. A simple calculation model is developed, which can be used to determine the glass temperatures in various facade configurations in accordance with the relevant standards. The results show that while parts of the existing requirements are still valid, there are distinct differences in the requirements for more modern applications.

description: The effects of a nonzero photon rest mass can be incorporated into electromagnetism in a simple way using the Proca equations. In this vein, two interesting implications regarding the possible existence of a massive photon in nature, i.e., tiny alterations in the known values of both the anomalous magnetic moment of the electron and the gravitational deflection of electromagnetic radiation, are utilized to set upper limits on its mass. The bounds obtained are not as stringent as those recently found; nonetheless, they are comparable to other existing bounds and bring new elements to the issue of restricting the photon mass.

description: Façade maintenance has become a key aspect in building management, due the specific actions involved and operation related costs. In this frame, the application of titanium dioxide photocatalytic sol-gel products on façade elements offers a wide range of opportunities to ensure proper functionalities maintenance overtime. This paper illustrates the self-cleaning performance of titanium dioxide and silicon dioxide based coatings applied to different kind of cladding materials. All tested samples were opaque. Preliminary laboratory tests were performed to verify hydrophobic and hydrophilic behaviour, prior to outdoor application, through water contact angle measurements. Afterwards, outdoor tests were performed to monitor color variation during 36 months to verify product effectiveness and its durability. Results proved that the application of functionalized nanotechnological coating to façade can significantly ease cleaning operations and reduce their necessary frequency over time. In addition, output provide some preliminary information about exposure condition influence on self-cleaning performance, which could be further investigated in the future.

The dynamical evolution of the density and the vorticity takes into account the interchange instability and magnetic field inhomogeneities. First, in order to described the Finite Larmor Radius effects we apply the gyromap to build a Hamiltonian model with ion temperature from a cold-ion model. Second, we show that the gyromap is justified using Braginskii's closure for the stress tensor as well as an apt ordering on the fluctuating quantities.

Slow EIT waves as gravity modes

description: The EIT waves [named after the Extreme-ultraviolet Imaging Telescope (EIT) onboard the Solar and Heliospheric Observatory (SOHO)] are in the literature usually described as fast magneto-acoustic (FMA) modes. However, observations show that a large percentage of these events propagate with very slow speeds that may be as low as 20 km/s. This is far below the FMA wave speed which cannot be below the sound speed, the latter being typically larger than $10^2$ km/s in the corona. In the present study it is shown that, to account for such low propagation speed, a different wave model should be used, based on the theory of gravity waves, both internal (IG) and surface (SG) ones. The gravity modes are physically completely different from the FMA mode, as they are essentially dispersive and in addition the IG wave is a transverse mode. Both the IG and the SG mode separately can provide proper propagation velocities in the whole low speed range.

description: Deformations of minimal surfaces lying in constant time slices in static space-times are studied. An exact and universal formula for a change of the area of a minimal surface under shifts of nearby point-like particles is found. It allows one to introduce a local temperature on the surface and represent variations of its area in a thermodynamical form by assuming that the entropy in the Planck units equals the quarter of the area. These results provide a strong support to a recent hypothesis that gravity has an entropic origin, the minimal surfaces being a sort of holographic screens. The gravitational entropy also acquires a definite physical meaning related to quantum entanglement of fundamental degrees of freedom across the screen.

A hybrid data-driven BSDF model to predict light transmission trough complex fenestration systems including high incident directions
Creators: name: Krehel, Marek

name: Wittkopf, Stephen

description: The transmission and distribution of light through Complex Fenestration Systems (CFS) impacts visual comfort, solar gains and the overall energy performance of buildings. For most fenestration, scattering of light can be approximated as the optical property of a thin surface, the Bidirectional Scattering Distribution Function (BSDF). It is modelled in simulation software to replicate the optical behaviour of materials and surface finishes. Data-driven BSDF models are a generic means to model the irregular scattering by CFS employing measured or computed data-sets. While measurements are preferred by researchers aiming at realism, they are constraint by the measurement geometries of the employed instrumentation. Particularly for large samples prevailing in the field of building sciences, measurements of the BSDF for directions close to grazing are impacted by shadowing and edge effects. Reliable extrapolation techniques are not available due to the irregularity of the BSDF. Computational simulation is not limited by such constraints at the cost of lower realism. A hybrid approach is therefore proposed. The BSDF of a CFS is measured for incident elevation angles from 0° to 60°. For incident elevation angles from 0° to 85°, the BSDF of the sample is computed. The BSDF acquired by both techniques in the overlapping range of directions between 0° to 60° is compared and reveals good qualitative accordance. The variance of the direct-hemispherical reflection and transmission based on the two techniques is between 3% and 28%. A hybrid data-set is then generated, utilizing measurements where possible and simulations where instrumentation cannot provide reliable data. A data-driven model based on this data-set is implemented in simulation software. This hybrid model is tested by comparison with the geometrical model of the sample. The hybrid approach to BSDF modelling shall support the utilization of BSDF models based on measured data by selectively overcoming the lack of reliable measured or extrapolated data.

description: Dear JFDE Readers and Authors, After four volumes of JFDE we can conclude that JFDE is still being seen as a ‘young’ journal just as the scientific area it is aiming to serve. In the past, building envelope related papers have been published in structure or building physics related journals. But with the development of the professional field the scientific community grows as well, and with it JFDE is enjoying more and more acknowledgement. One result is that we have been able to become the scientific partner of two conferences: ‘Powerskin’ in January 2017 at the BAU building trade fair in Munich and the ICBEST International Conference on Building Envelopes Systems and Technologies, May 2017 in Istanbul. Both events will be covered in two special issues. This development stimulates us to continuously evaluate the future scope of JFDE. In this sense, we are proud to present a new issue of JFDE with innovative contributions that target both the design and engineering of building envelopes. Two papers focus on a better understanding of facades in a technical sense. The first one predicts light transmission trough complex fenestration systems including high incident directions, the other aims at understanding the increased thermal load, the effect on structural safety of insulated glass units and the implications for norms and regulations. Two other contributions focus on novel applications: The first one looks at photocatalytic self-cleaning coatings for building façade maintenance. The application of Nano technologies is rather new and it is important to explore the potential it might provide to the discipline. The second one researches biomimetic inspired natural ventilation facades with integrated green. Such combination is prototypic of the scope we envision for JFDE. A good mixture of technical and innovative contributions, always trying to relate science and practice, design and engineering. The editors in chief, Tillmann Klein Ulrich Knaack

description: We investigate the use of a certain class of functional inequalities known as weak Poincaré inequalities to bound convergence of Markov chains to equilibrium. We show that this enables the straightforward and transparent derivation of subgeometric convergence bounds for methods such as the Independent Metropolis--Hastings sampler and pseudo-marginal methods for intractable likelihoods, the latter being subgeometric in many practical settings. These results rely on novel quantitative comparison theorems between Markov chains. Associated proofs are simpler than those relying on drift/minorization conditions and the tools developed allow us to recover and further extend known results as particular cases. We are then able to provide new insights into the practical use of pseudo-marginal algorithms, analyse the effect of averaging in Approximate Bayesian Computation (ABC) and the use of products of independent averages, and also to study the case of lognormal weights relevant to particle marginal Metropolis--Hastings (PMMH).

description: This paper addresses the thermal bridges issues of a two storey lightweight steel framed envelope in which the VIPs are placed in an inner “protected” layer of the external walls. This configuration provides “protection” for the VIPs, allows flexibility in installation of façade elements and at the same time permits interventions and modifications (e.g. drilling, installation of appliances) on the internal side of the wall. The envelope is extensively analyzed in terms of all the different types of thermal bridges utilizing commercial computational tools and standardized methodologies and their effect on the overall thermal performance is evaluated. A total improvement of 33% on the heat transfer coefficient of the building is estimated. Results indicate the junctions between the external and internal walls, the external walls and the ceiling, the internal walls and the roof and the internal walls and the floor, respectively, as the most crucial thermal bridges. Different design modifications and solutions are assumed in order to further reduce the impact of the most crucial thermal bridges. The implementation of the modifications resulted to a further reduction of the overall thermal losses by 27.5%, leading to an overall thermal loss reduction by 60.5% when compared to the reference building.

Enhanced Flame retardancy of flax-biocomposites for the construction market

Publisher: name: Journal of Facade Design and Engineering
Year: 2016

description: Biocomposites are made of natural fibers which are an attractive alternative to conventional synthetic fibers such as glass or carbon fibers not only because their intrinsic properties but also because their contribution to more sustainable materials. However, natural fibres are flammable and the biocomposites need to be protected against fire for safety reasons but also to meet the strictest EU regulations of the transport and construction sectors. Thermosetting composites need high loadings of flame retardant additives to achieve satisfactory results in terms of flammability. However, high levels of flame retardants lead to significant deterioration in mechanical properties. This work explores the possibility of reducing the flammability of flax-biopolyester composites with potential uses in transport and construction sectors through the combination of several novel fire retardant additives which are halogen free and are considered environmentally friendly. Cone calorimeter tests indicate that proper combinations of FR additives reduced HRR and MARHE values up to a 60% delaying the ignition time with respect to the unfilled material. These results were achieved at concentrations much lower than with traditional solutions. However the addition of dimethyl propyl phosphonate (PMPP) to the resin formulation with ATH and APP failed to demonstrate any significant synergistic effect at reducing the HRR.

description: Russia has experienced a remarkable agricultural recovery during the past 20 years. Yet, food production is heavily concentrated in the top five and top ten regions. Russia’s agricultural recovery is narrow because leading regions account for a disproportional percentage of output. That narrowness fosters fragility, which suggests that a downturn in production among main producers may cause a spike in food insecurity. Second tier regions are not able to compensate for significant production declines in the top ten. The article explores four scenarios for narrowness going forward: continuation, expansion, slow decline, and collapse. Of the four scenarios, expansion is the only one that is either unlikely to occur or has not already occurred. The upshot is that Russia’s agricultural production base will remain narrow and fragile, a fact that impacts domestic food security and food security in its export markets.

description: Dans le cadre de cette thèse de maîtrise, nous nous intéressons à l’évolution de la thématique identitaire dans l’œuvre de Maryse Condé en ciblant trois romans principaux : Heremakhonon, Desirada et Le fabuleux et triste destin d’Ivan et d’Ivana, tout en faisant appel à d’autres romans de l’auteure qui peuvent approfondir notre raisonnement. Nous analysons la perspective de Maryse Condé sur l'identité antillaise qui évolue avec le temps à mesure qu'elle se détache de ses prédécesseurs, notamment Aimé Césaire à qui elle laisse une place prépondérante dans son œuvre. Plus précisément, nous examinons les différentes facettes de l’identité dans ces romans, au moyen de l’approche sociocritique, en tenant compte des contextes sociaux, en vogue lors de leur publication, qui mettent en lumière les problématiques identitaires abordées à travers ces textes littéraires. Pour tracer l’évolution de l’identité, nous avons repéré les répétitions et les différences évidentes qui traversent la diégèse de ces romans à travers quatre thèmes récurrents : la quête identitaire des personnages principaux, les espaces géographiques, l’errance et les nouveaux enjeux de la mondialisation.

description: In this paper, the non-Markovian dynamics of a microcavity coupled to a waveguide in photonic crystals is studied based on Fano-type tight binding model. Using the exact master equation, we solve analytically and numerically the temporal evolution of the cavity coherent state and the associated physical observables. A critical transition is revealed when the coupling increase between the cavity and the waveguide. In particular, the cavity field becomes dissipationless when the coupling strength goes beyond a critical value, as a manifestation of strong non-Markovian memory effect. The result also indicates that the cavity can maintain in a coherent state with arbitrary small number of photons when it strongly couples to the waveguide at very low temperature. These properties can be measured experimentally through the photon current flowing over the waveguide in photonic crystals.

description: Advance care planning (ACP) is a set of processes designed to help individuals express and document their preferences for future care and treatment interventions in accordance with their unique personal values. Prior research has identified healthcare chaplains as well-suited, yet potentially underutilized, facilitators of ACP given their expertise in spiritual care and healing. While ACP plays an important role in mapping patients’ long-term care plans, the physical and emotional strains of the COVID-19 pandemic have disrupted traditional avenues of ACP. As a result, this study analyzed 236 frontline accounts from board-certified healthcare chaplains to identify the ways in which COVID-19 has affected ACP across different clinical settings. Content analysis revealed two major themes: 1) COVID-19 has limited the scope of ACP and completion of advance directives, leading to 2) the emergence of legal, organizational, and technological adaptations in response to these challenges to continue supporting end-of-life care decision-making. Given the severity and progression of COVID-19, such findings suggest that there is heightened urgency for ACP, especially among patients and families who are unprepared or unfamiliar with navigating such conversations. This is further reinforced by the fact that ACP should ideally occur prior to a patient becoming critically ill, necessitating that healthcare professionals approach ACP education from a more proactive stance. Additionally, there may be future opportunities to incorporate the changes in ACP facilitation to foster greater interprofessional collaboration and accessibility through virtual platforms.

description: We study a class of dynamical semigroups $(\mathbb{L}^n)_{n\in\mathbb{N}}$ that emerge, by a Feynman--Kac type formalism, from a random quantum dynamical system $(\mathcal{L}_{ω_n}\circ\cdots\circ\mathcal{L}_{ω_1}(ρ_{ω_0}))_{n\in\mathbb{N}}$ driven by a Markov chain $(ω_n)_{n\in\mathbb{N}}$. We show that the almost sure large time behavior of the system can be extracted from the large $n$ asymptotics of the semigroup, which is in turn directly related to the spectral properties of the generator $\mathbb{L}$. As a physical application, we consider the case where the $\mathcal{L}_ω$'s are the reduced dynamical maps describing the repeated interactions of a system $\mathcal{S}$ with thermal probes $\mathcal{C}_ω$. We study the full statistics of the entropy in this system and derive a fluctuation theorem for the heat exchanges and the associated linear response formulas.

description: Building façades are Engineer-To-Order (ETO) products and, as such, they show unique features on a project-by-project basis. The partitioning of design tasks during the design and manufacturing process of these products, however, does not fully capture how specific design decisions influence other stakeholders’ choices. This lack of design integration is most severe at early stages when a large proportion of initial costs, mostly driven by manufacturability aspects, is determined. This paper illustrates a methodology to build Knowledge-Based Engineering (KBE) applications to support early-stage design integration through the development of a façade Product Model for automatic rule checking and knowledge reuse. The main outcome is a preliminary framework for developing knowledge-based, digital tools to support and integrate façade design as well as different scenarios in which the tool can potentially be used, based on two types of procurement methods. A prototype of the tool is also shown here. The paper proposes a new paradigm where façade systems are considered to be more closely related to Make-To-Order types, rather than ETOs, in which the product is ready for fabrication and designers can rapidly explore the subcontractor’s manufacturing capabilities and the implications of their design choices. Future work will include tool validation by applying the tool into a specific façade manufacturer’s workflow.

description: Sentiment analysis of microblogs such as Twitter has recently gained a fair amount of attention. One of the simplest sentiment analysis approaches compares the words of a posting against a labeled word list, where each word has been scored for valence, -- a 'sentiment lexicon' or 'affective word lists'. There exist several affective word lists, e.g., ANEW (Affective Norms for English Words) developed before the advent of microblogging and sentiment analysis. I wanted to examine how well ANEW and other word lists performs for the detection of sentiment strength in microblog posts in comparison with a new word list specifically constructed for microblogs. I used manually labeled postings from Twitter scored for sentiment. Using a simple word matching I show that the new word list may perform better than ANEW, though not as good as the more elaborate approach found in SentiStrength.

description: Graphene nanoribbons show exciting electronic properties related to the exotic nature of the charge carriers and to local confinement as well as atomic-scale structural details. The local work function provides evidence for such structural, electronic and chemical variations at surfaces. Kelvin prove force microscopy (KPFM) can be used to measure the local contact potential difference (LCPD) between a probe tip and a surface, related to the work function. Here we use this technique to map the LCPD of graphene nanoribbons grown on a Au(111) substrate. The LCPD data shows charge transfer between the graphene nanoribbons and the gold substrate. Our results are corroborated with density functional theory calculations which verify that the maps reflect from the doping of nanoribbons. Our results help to understand the relation between atomic structures and electronic properties.
Thermal optimization of curtain wall façade by application of aerogel technology
Creators: name: Appelfeld, David
Publisher: name: Journal of Facade Design and Engineering
Year: 2017

description: The paper illustrates the use of aerogel technology in façades to reduce thermal bridging and limit condensation. Additionally by mitigating local thermal bridges the indoor climate, especially draught and molds creation, can be eliminated as the surface temperature increases and prevents these negative factors. Curtain walls, in comparison to opaque wall, are often not designed in an energy efficient way and can be large contributors to heat loss of buildings. This is common for curtain walls in Asia and North America, where the energy requirements are not as demanding as in Europe. Building envelopes have many details which can easily introduce thermal bridge due to limited space of insulation or incorrectly solved construction detail. The heat flow through a poor thermally-performing detail, e.g. exposed concrete slab, could account for over 40% of the heat loss of the façade. The contribution of a well-insulated slab could be less than 10%. Unfortunately, traditional insulation techniques are often not suitable due to limited installation space. This paper discusses several case studies whereby the performance of a reference case is compared to a case with a thermally optimized façade implementing Building Insulation Blanket (BIB), which uses silica based aerogel technology. The thermal conductivity of BIB can be as low as 0.015W/mK, and together with its high flexibility and fire resistance enables new design possibilities. The use of BIB in the case studies, contributed to the reduction of overall curtain wall thermal transmittance up to 30%. Additionally condensation risk was significantly reduced.

description: In the field of access control, delegation is an important aspect that is considered as a part of the administration mechanism. Thus, a complete access control must provide a flexible administration model to manage delegation. Unfortunately, to our best knowledge, there is no complete model for describing all delegation requirements for role-based access control. Therefore, proposed models are often extended to consider new delegation characteristics, which is a complex task to manage and necessitate the redefinition of these models. In this paper we describe a new delegation approach for extended role-based access control models. We show that our approach is flexible and is sufficient to manage all delegation requirements.
Topics in Siamou tense and aspect

description: This dissertation examines the syntax and semantics of tense and aspect in Siamou (Niger-Congo, Kru), a language of Burkina Faso. Its purpose is twofold. First, it provides a description of the tense/aspect system of Siamou; to date, this part of the grammar has not been systematically investigated. Second, it tests and sharpens formal syntactic and semantic tools relating to tense and aspect on Siamou data. It shows that applying standard analyses to a previously unanalyzed tense/aspect system is effective. For example, existing tests for perfective and imperfective aspect are able to diagnose two of Siamou's aspectual morphemes. However, it also points out some key areas that need work, including how Siamou past tense implicatures arise, and what kind of modality Siamou future expressions encode. Chapter 1 provides background information on tense and aspect, describes the methodology used, and introduces topics covered in this dissertation. Chapter 2 provides an overview of properties of Siamou that are relevant to the description and analysis of tense and aspect in this language. Chapter 3, which is a morpho-syntactic description and analysis of the Siamou aspectual phrase, establishes that Siamou has a set of six aspectual suffixes that partition into three tonal classes: a low tone class, which includes -L, -è, and -ɲɛ̀n, a mid tone class, which includes -n and -a, and a high-low tone class, which includes -bɛ̂. This is followed by a theoretical chapter which develops a set of semantic diagnostics for perfective and imperfective aspect. Chapter 5 uses those diagnostics to show that one of the aspectual markers, the low tone suffix, encodes perfective aspect while another, the mid tone nasal consonant suffix, encodes imperfective aspect. Chapter 6 investigates the semantics of the right-edge particle ín, and argues that its primary meaning is past tense. I show that this particle also gives rise to a number of implicatures that are consistent with its primary meaning. Finally, chapter 7 examines Siamou's future expressions (ri. . .-a, bè. . .-a, and bè. . .-bɛ̂). I show that the future meaning makes use of three syntactic positions: finiteness, modality, and prospective aspect.
