description: La tesi verte sull?analisi della comprensibilita? e della leggibilita? di un corpus di testi istituzionali italiani destinati agli stranieri e sulla sperimentazione di soluzioni redazionali e didattiche efficaci. E? noto che il linguaggio istituzionale italiano (soprattutto nelle varianti utilizzate dalle amministrazioni e dal diritto) spesso tende ad essere inutilmente complicato, soprattutto per gli stranieri che devono necessariamente far fronte a numerose pratiche burocratiche ed amministrative per poter risiedere sul territorio italiano; la ricerca intende agevolarne l?integrazione facilitando l?accesso ai documenti. Per poter raccogliere quante piu? informazioni possibili sugli elementi che definiscono comprensibilita? e leggibilita? di questa tipologia di testi riguardo all?utenza straniera, si e? deciso di creare un corpus di testi istituzionali destinati ai migranti (ISTR) e di analizzarlo in maniera computazionale. Allo stesso tempo 101 studenti stranieri sono stati testati nella comprensione di diversi testi istituzionali a loro rivolti. Grazie all?analisi dei dati e? stato possibile stilare un elenco delle marche linguistiche di difficolta? del linguaggio istituzionale destinato agli stranieri e dei fattori cognitivi, socio-linguistici ed emotivi che intervengono durante il processo di comprensione. In seguito, sono state selezionate due strategie per il miglioramento della comprensione: la semplificazione del testo e l?ideazione di un corso di formazione sul linguaggio istituzionale italiano. L?analisi statistica (dependent t-test e Anova test) dei dati e la comparazione tra i gruppi di studenti mostra che sia la semplificazione (df = 59, p- value = 1.066e-09) dei testi sia la frequenza del corso di formazione migliorano la comprensione dei testi istituzionali (F value = 4.56, p- value=0.037 *). I risultati mostrano che la congiunzione di sforzi istituzionali (con la redazione di testi a difficolta? controllata per gli stranieri) ed educativi (con la creazione di corsi di lingua specifici) puo? effettivamente agevolare l?integrazione dei migranti nel tessuto socio- politico delle comunita? di accoglienza.

description: Gakkel Ridge, the active spreading center in the Arctic Ocean, is the slowest spreading portion of the global mid-ocean ridge system. Total spreading rates range from 0.6 cm/yr in the east where the ridge disappears beneath the Laptev shelf to 1.3 cm/yr in the west near Greenland. Bathymetry and gravity surveys of four sections of the Gakkel Ridge were carried out in 1996 by the U.S. Navy nuclear submarine USS POGY as part of SCICEX 96 in order to sample variations in seafloor morphology and gravity anomalies as a function of spreading rate. The ridge axis throughout the survey area is characterized by a continuous axial rift valley similar to that observed at other slow spreading ridges. The continuous rift axis suggests that well-organized seafloor spreading is occurring at total spreading rates of less than 1 cm/yr. In three faster spreading (1.13–1.24 cm/yr) western survey areas located between 7ºE and 54ºE, the Gakkel Ridge is deep compared with other ridge axes. Axial depths range between 4600 and 5100 m and ridge flanks at about 3200 m. The ridge flank morphology is very blocky and is characterized by large scarps and deep fault-bounded troughs. Very large amplitude free-water anomalies with peak-to-trough amplitudes of 85–150 mGal are observed centered on the axis of the Gakkel Ridge. Modeling of the free-water anomalies by varying the crustal thickness and average crustal density, including the gravity effect of the cooling of the mantle away from the axis, implies that if the average crustal density is less than 2900 kgm3, the crustal thickness must be less than 4 km. The axial rift valley at the fourth survey area, near 98ºE where the total spreading rate is 0.99 cm/yr, is buried by sediments. The axis in this region is associated with a continuous 70 mGal gravity minimum implying the presence of a large buried rift valley. The rift flanks at 95ºE are at a depth of greater than 3800 m, 600 m deeper than the average depth at the Gakkel Ridge axis west of 60ºE. Simple isostatic calculations suggest that the crust in this region may be vanishingly thin beneath the sediment cover. These observations indicate a relationship between melt production and seafloor spreading rate at very slow spreading rates, suggesting that ultra-slow spreading may suppress melt production or delivery at the Gakkel Ridge.

description: There is a systematic variation in axial morphology and axial depth along the Southeast Indian Ridge (SEIR) with distance away from the Australian Antarctic Discordance, an area of cold uppermost mantle. Since spreading rate (72–76 mm/yr) and mantle geochemistry appear constant along this portion of the SEIR, the observed variations in axial morphology and axial depth are attributed to a gradient in mantle temperature. In this study, we report results from a multichannel seismic investigation of on-axis crustal structure along this portion of the SEIR. Three distinct forms of ridge crest morphology are found within our study area: axial highs, rifted axial highs, and shallow axial valleys. Axial highs have a shallow (~ 1500 m below seafloor (bsf)) magma lens and a thin (~ 300 m) layer 2A along the ridge crest. Rifted axial highs have a deeper (~ 2100 m bsf) magma lens and thicker (~ 450 m) layer 2A on-axis. Beneath shallow axial valleys, no magma lens is imaged, and layer 2A is thick (~ 450 + m). There are step-like transitions in magma lens depth and layer 2A thickness with changes in morphology along the SEIR. The transitions between the different modes of axial morphology and shallow structure are abrupt, suggesting a threshold-type mechanism. Variations in crustal structure along the SEIR appear to be steady state, persisting for at least 1 m.y. Portions of segments in which a magma lens is found are characterized by lower relief abyssal hills on the ridge flank, shallower ridge flank depths, and at the location of along-axis Mantle Bouguer Anomaly (MBA) lows. The long-wavelength variation in ridge morphology along the SEIR from axial high segments to the west to axial valley segments to the east is linked to the regional gradient in mantle temperature. Superimposed on the long-wavelength trend are segment to segment variations that are related to the absolute motion of the SEIR to the northeast which influence mantle melt production and delivery to the ridge.

description: We study the scattering of graphene quasiparticles by topological defects, represented by holes, pentagons and heptagons. For the case of holes, we obtain the phase shift and found that at low concentration they appear to be irrelevant for the electron transport, giving a negligible contribution to the resistivity. Whenever pentagons are introduced into the lattice and the fermionic current is constrained to move near one of them we realize that such a current is scattered with an angle that depends only on the number of pentagons and on the side the current taken. Such a deviation may be determined by means of a Young-type experiment, through the interference pattern between the two current branches scattered by a pentagon. In the case of a heptagon such a current is also scattered but it diverges from the defect, preventing a interference between two beams of current for the same heptagon.
Air pollution in New Delhi, India : spatial and temporal patterns of ambient concentrations and human exposure

description: Urban air pollution is a major health and environmental concern worldwide, and the levels are extremely high in New Delhi, India. This research is focused on the spatial and temporal variability of air pollutant concentrations and its implications for population exposure in New Delhi. Since traffic is considered a significant source of air pollutants in urban environments, robust and multiple linear regression models were used to understand the impact of local traffic flow on ambient concentrations of PM₂.₅, CO, NO and NO₂ at a busy intersection. To elicit the spatiotemporal variability of PM₂.₅ and its constituents (black carbon and ultrafine particles), land use regression (LUR) models were developed. Separate morning and afternoon models were developed using 136 hours (39 sites), 112 hours (26 sites) and 147 hours (39 sites) of PM₂.₅, BC and UFPN data, respectively. Finally, to understand how spatiotemporal variations in PM₂.₅ concentrations impact population exposure, a probabilistic simulation framework was developed to integrate the PM₂.₅ LUR models with time-activity data obtained from a field survey. Regression models explained about 50–80% variability in hourly pollutant concentrations and localized traffic flow explained up to 19% of variability on that scale. Auto-rickshaw and truck flow had a higher influence on NO₂ and PM₂.₅ concentrations, respectively. Independent variables in the LUR models included population density, distance from major roads, and major and minor road lengths in buffers of different radii; measurements from a fixed continuous monitoring site were also used as independent variables in the PM₂.₅ and BC models. The temporal term explained most of the variability (63–77%) in PM₂.₅ and BC models compared to spatial variables (4–16%). Exposure simulations indicate that the estimated annual average PM₂.₅ exposure (109 µg m-³) was high compared to North American or European cities. PM₂.₅ exposures were highest during the winter months (~200 µg m-³) compared to the summer months (~50 µg m-³). Ignoring mobility (i.e. exposure during transport or at work/school locations), as is generally assumed in epidemiologic studies of long-term exposure, underestimated PM₂.₅ population exposure by about 11%.

Juvenile Hormone esterase is a conserved regulator of starvation-induced behavior
Creators: name: Stafford, Jeffrey
Publisher: name: University of British Columbia

description: Although feeding behavior is a matter of life and death for animals, the genetic factors that control it remain poorly understood. We have identified a novel regulator of hunger-induced behavior through comparison of transcriptomic changes in the fruit fly Drosophila melanogaster and the yellow fever mosquito Aedes aegypti. Head mRNA from each insect was sequenced at a roughly equivalent level of starvation. Using data gleaned from the protein orthology database OrthoDB, we looked for gene pairs in which both A. aegypti and D. melanogaster orthologs were significantly regulated by starvation. This identified Juvenile Hormone esterase (Jhe) as a possible modulator of hunger-induced behavior. Pan-neuronal knockdown of Jhe resulted in increased food consumption and caused enhancement of starvation-induced sleep suppression in Drosophila. These behavioral phenotypes were not caused by a developmental or metabolic defects, and were reproduced by feeding adult Drosophila methoprene, a synthetic Juvenile Hormone analog. Application of precocene I, an inhibitor of Juvenile Hormone biosynthesis, reversed the phenotype. Our analysis suggests that Jhe (and Juvenile Hormone by extension) is a novel and biologically relevant regulator of hunger-induced behavior.

description: The temperature of the mantle and the rate of melt production are parameters which play important roles in controlling the style of crustal accretion along mid-ocean ridges. To investigate the variability in crustal accretion that develops in response to variations in mantle temperature, we have conducted a geophysical investigation of the Southeast Indian Ridge (SEIR) between the Amsterdam hotspot and the Australian-Antarctic Discordance (88°E- 118°E). The spreading center deepens by 2100 m from west to east within the study area. Despite a uniform, intermediate spreading rate (69-75 mm yr- 1), the SEIR exhibits the range in axial morphology displayed by the East Pacific Rise and the Mid-Atlantic Ridge (MAR) and usually associated with variations in spreading rate. The spreading center is characterized by an axial high west of 102°45'E, whereas an axial valley is prevalent east of this longitude. Both the deepening of the ridge axis and the general evolution of axial morphology from an axial high to a rift valley are not uniform. A region of intermediate morphology separates axial highs and MAR-like rift valleys. Local transitions in axial morphology occur in three areas along the ridge axis. The increase in axial depth toward the Australian-Antarctic Discordance may be explained by the thinning of the oceanic crust by ~ 4 km and the change in axial topography. The long-wavelength changes observed along the SEIR can be attributed to a gradient in mantle temperature between regions influenced by the Amsterdam and Kerguelen hot spots and the Australian-Antarctic Discordance. However, local processes, perhaps associated with an heterogeneous mantle or along-axis asthenospheric flow, may give rise to local transitions in axial topography and depth anomalies.

description: NEWSERA Blueprints for citizen science communication (#citscicomm) with and for quadruple helix stakeholders (citizens and society at large, academic scientists, public sector and policymakers, industry and SMES) and science and data journalists is an instrument that can serve a general audience, including those who are planning to start a citizen science (CS) project, those who want to improve and/or rethink their communication strategies in order to increase specific target audiences, or those who want to enlarge their scope of action by involving the different actors of the quadruple helix model and the media. The road for CS projects establishment and sustainability is long and there are many barriers to be faced. But you are not alone! Together with 39 CS projects from Italy, Spain and Portugal, the NEWSERA Pilots, we have tested the NEWSERA methodology for the co-design, implementation, iterative assessment and validation of communication strategies directed to each of the quadruple helix stakeholders and science and data journalists. This was performed through our #CitSciComm Labs, dedicated to each individual stakeholder, consisting of three rounds of workshops, replicated in each of the participating countries, throughout three years. In this series of five blueprints, NEWSERA brings the learnings of this co-created process together with our pilots, invited stakeholders and science communication experts (NEWSERA Sounding Board) that was complemented with mentoring, capacity building and networking sessions, generating knowledge, recommendations and useful resources. In this blueprint, dedicated to citizen scientists and society at large as target stakeholder, you will find, more in depth, the importance to address this stakeholder, good practices on the co-design of targeted communication plans, elements of co-design, mutual benefits of CS project-stakeholder, and indicators. Furthermore, a description and details of messages, innovative tools, channels and specific case-studies from the NEWSERA Pilots are included. Finally, we shared a series of recommendations to efficiently engage with quadruple helix stakeholders and science and data journalists for wider impact and ensure replicability of the NEWSERA findings and science communication strategies in citizen science projects and beyond.

Interestingly in addition to the usual Goldstone mode, there exists three other "optical" spin wave branches. These spin excitations are the analog of "optical phonons" in crystals with more than one atom per unit cell. We compute the spin wave corrected ordering moment and the uniform spin susceptibilities.

New methods for deblending spectral energy distributions in confused imaging
Creators: name: MacKenzie, Todd
Publisher: name: University of British Columbia
Year: 2016

description: The submillimetre band is ideal for studying high-redshift star-forming galaxies, but such studies are hampered by the poor resolution of single-dish telescopes. Interferometric follow-up has shown that many sources are in fact comprised of multiple sources. For many such targets, confusion-limited Herschel observations that target the peak of their far-infrared emission are also available. Many methods for analysing these data have been developed, but most follow the traditional approach of extracting fluxes before model spectral energy distributions are fit, which erases degeneracies among fitting parameters and glosses over the intricacies of confusion noise. We have developed a forward-modelling method in order to tackle this problem in a more statistically rigorous way, which combines source deblending and spectral energy distribution fitting into the same procedure. We adapt our method to three independent projects, all of which benefit from our improved methodology. We investigate a "giant submillimetre arc" behind a massive foreground cluster and uncover seven multiply imaged galaxies, of which six are found to be at a redshift of z~2.9, and possibly constitute an interacting galaxy group. Using our new method, we disentangle the arc into its contributing components and constrain their far-IR properties. Using confusion limited Herschel-SPIRE imaging, the far-IR properties LABOCA detected submillimetre sources can be constrained. Despite such sources often breaking up in high-resolution ALMA imaging, existing studies have implemented traditional fitting methods. We apply our new forward modelling method to re-derive constraints on the far-infrared properties of these sources, exploring selection effects on this sample, while highlighting the benefits of our fitting approach. Finally, we present SCUBA-2 follow-up of 51 candidate proto-cluster fields undergoing enhanced star-formation. With the accompanying Herschel-SPIRE observations and a realistic dust temperature prior, we provide photometric redshift and far-IR luminosity estimates for 172 SCUBA-2 selected sources within the Planck overdensity fields. We find a redshift distribution similar to sources found in cosmological surveys, although our fields are enhanced in both density of sources and star formation rate density over a wide range of redshifts.
Bathymetric roughness of the Southeast Indian Ridge: Implications for crustal accretion at intermediate spreading rate mid-ocean ridges

description: The nature of the transition from axial highs to axial valleys at mid-ocean ridges and the physical processes involved in the transition are important for understanding how axial morphology changes with spreading rate, mantle temperature, and lithospheric strength at mid-ocean ridges. In order to provide observational constraints on the nature of the changes in axial mo11Jhology, we examined the regional- and segment-scale variations in axial and flank morphology at the intermediate spreading Southeast Indian Ridge (SEIR) using newly collected geophysical data. An empirical orthogonal function analysis was used to separate regional and local components of the topography field and to estimate bathymetric roughness. Three distinct types of axial morphology were identified from the regional component of ridge topography in our area: axial highs, shallow axial valleys, and "Mid-Atlantic Ridge-type" deep axial valleys. Axial depth increases by -2100 m from 88°E and l18 °E, while off-axis depth only increases by -500 m. In addition, except for one segment with a deep axial valley, there is little change in off-axis depth within segments, in contrast to the large intrasegment variations in axial depth. These observations indicate that the overall and intrasegment variations in crustal thickness are much smaller than would be predicted from the variations in axial depth and that the major portion of the variations in ridge axis depth are dynamically supported. There are step-like increases in bathymetric roughness as axial morphology changes from an axial high to a shallow axial valley and from a shallow axial valley to a deep axial valley. The step changes in roughness imply that the change from one mode of axial morphology to another is accompanied by an abrupt change in the strength of the lithosphere. The abrupt changes in lithospheric strength may be due to the existence of a "threshold" mantle temperature or crustal thickness about which the lithospheric strength is very sensitive to small fluctuations. Systematic intrasegment variations in roughness are also observed. Roughness shows V-shaped patterns within segments with axial highs but no clear pattern within segments with axial valleys. The different patterns in roughness at axial highs and axial valleys on the SEIR may result from the presence or absence of a magma chamber. The presence of a magma chamber at a ridge segment with an axial high implies weaker axial lithosphere and hence lower roughness near the center of segments relative to the segment ends.
The times they are a-changin : flexible meter and text expression in 1960s and 70s singer-songwriter music
Creators: name: Murphy, Nancy Elizabeth
Publisher: name: University of British Columbia
Year: 2016

description: The 1960s and 70s saw the flowering of the singer-songwriter style, which featured acoustic performances by artists who were the composers and lyricists of their own music. Reflecting their culture, their songs carried messages of personal and political significance. But their music is of technical as well as of social interest. Like classical art song, it often highlights lyrical meaning with various sorts of metric irregularities. In this dissertation, I closely analyze twenty-seven songs by Bob Dylan, Paul Simon, Buffy Sainte-Marie, Joni Mitchell, and Cat Stevens, in order to characterize the metric style of their songwriting and demonstrate their use of meter as an expressive device. To describe meter in this music requires theories more flexible than those usually applied to groove-based music. The analyses in this dissertation draw not only from theories of meter as a hierarchy of beat streams, but also upon theories of metrical process and prosody, in order to create transcriptions, to describe precisely listeners' sensations of meter, and to propose expressive rationales for metric settings. As an introduction to the style and the theoretical issues, Chapter 1 considers the problems of conceiving of meter in the expressively timed context of Mitchell’s “The Fiddle and the Drum.” Chapter 2 examines the existing methods for analyzing meter in music and poetry, in order to find some productive ways to analyze this metrically fluctuant repertoire. Chapter 3 considers transcription as analysis, showing that one's conception of meter informs and constrains musical representation, and therefore interpretations of lyrical meaning. In Chapter 4, I position 1960s and 70s songwriting in its cultural and political environment, reviewing some stylistic precedents to understand their influence, and determine its original metrical techniques. In the remaining analytical chapters, I examine meter-text expression in songs by Simon, Sainte-Marie, and Stevens (Chapter 5), the expression of character and lyrical personae in the narratives of three solo-piano-accompanied songs by Mitchell (Chapter 6), and how Dylan adapted text-expressive metric techniques of earlier genres in a variety of original ways (Chapter 7).

Constrained model predictive control of hypnosis
Creators: name: Khosravi, Sara
Publisher: name: University of British Columbia
Year: 2016

description: This thesis investigates the design and performance of a model predictive controller (MPC) for the automatic control of hypnosis. It constitutes the first step towards automatic control of anesthesia with constraints on important parameters such as drug concentrations in the body and hemodynamic variables such as blood pressure. The literature suggests, that closed-loop control of anesthesia can significantly reduce drug consumption and lessen recovery times, thus improving the safety and quality of anesthesia care while reducing costs. However, automation of anesthesia is challenging because of shortcomings associated with drug-response modeling, in particular limited data for children and disagreement between published models, inadequate predictive capacity of models owing to inclusion of monitor dynamics in the models, and significant inter/intra patient variability and uncertainty in models. The first part of this thesis introduces a new approach to dose-response modeling and presents models with different clinical end-points for propofol in children and adults. This thesis also presents a new monitor-decoupledmodel of propofol pharmacodynamics (PD) where the monitor model is clearly excluded from the identified PD. The second part of the thesis concentrates on design of a constrained MPC for hypnosis. While the anesthesia closed-loop concept has already been investigated in the past, there is still a need for a closed-loop control system that explicitly includes robustness in the design step, allows constraints on drug concentrations and physiological parameters, and can incorporate multivariable control of multi drug and multi sensor systems. In this thesis, robust MPC controllers are presented for closed-loop control of depth of hypnosis in adults and children. Robustness in the presence of inter-patient variability is taken into account in the controller design. A novel idea is introduced on how to define and implement physiological constraints in closed-loop control of hypnosis using MPC with a parallel PKPD model. Evaluation of the proposed MPC meets the design specifications and shows that the required robustness against patient uncertainty is achieved and the proposed safety constrained control strategy can potentially reduce the risk of under/over-dosing for most patients by providing controller enforced safety bounds without sacrificing the performance of the closed-loop control system.
Modeling the surge beds in the emergency department in a hospital by Markov decision process and queueing theory

Publisher: name: University of British Columbia
Year: 2016

description: In this thesis, we apply Markov decision theory to the problem involving M(t)/M/c/c queue to conduct a case study at Kelowna General Hospital (KGH) in British Columbia, Canada. Health-care systems have been challenged in recent years to deliver high quality care with limited resources. Emergency departments (ED) are perhaps the most sensitive components of the health-care system due to their nature. KGH has extra beds in its ED in a unit called the surge section. They use this section in case the ED is overcrowded. There is no systematic approach to when this section should be in use, and managerial decisions are made based on the what seems necessary at the time. Obviously, these decisions are usually costly and not based on a careful analysis. Therefore, they want to have a policy to know when to use the surge section. In this thesis, first we adapt the fourth order Runge-Kutta method (RK4) to obtain more accurate transient solutions for M(t)/M/c/c queues. We show numerically that our method works better than RK4 for our specific queue. Then we provide the Markov decision process (MDP) model for solving the problem. In this model, the arrival rate is time-dependent, and there are two levels for the number of servers. We prove that decisions for an MDP with periodic and time-dependent Poisson arrivals are periodic as well. Consequently, the contour control policies which are obtained based on the optimal decision show periodic behavior as well. Numerical results presented support this claim. Moreover, we model the seasonal flu epidemics and define a combined arrival rate for the ED. The results of this model support the claim about the periodicity of the policies as well. In addition, we show that a type of linear extrapolation is a reliable way to obtain control polices for large-scale problems.

description: The Gakkel Ridge in the Arctic Ocean is the slowest spreading portion of the global mid-ocean ridge system. Total spreading rates range from 12.7 mm/yr near Greenland to 6.0 mm/yr where the ridge disappears beneath the Laptev Shelf. Swath bathymetry and gravity data for an 850 km long section of the Gakkel Ridge from 5°E to 97°E were obtained from the U.S. Navy submarine USS Hawkbill. The ridge axis is very deep, generally 4700–5300 m, within a well-developed rift valley. The topography is primarily tectonic in origin, characterized by linear rift-parallel ridges and fault-bounded troughs with up to 2 km of relief. Evidence of extrusive volcanic activity is limited and confined to specific locations. East of 32°E, isolated discrete volcanoes are observed at 25 - 95 km intervals along the axis. Abundant small-scale volcanism characteristic of the Mid-Atlantic Ridge (MAR) is absent. It appears that the amount of melt generated is insufficient to maintain a continuous magmatic spreading axis. Instead, melt is erupted on the seafloor at a set of distinct locations where multiple eruptions have built up central volcanoes and covered adjacent areas with low relief lava flows. Between 5°E and 32°E, almost no volcanic activity is observed except near 19°E. The ridge axis shoals rapidly by 1500 m over a 30 km wide area at 19°E, which coincides with a high-standing axis-perpendicular bathymetric high. Bathymetry and side scan data show the presence of numerous small volcanic features and flow fronts in the axial valley on the upper portions of the 19°E along-axis high. Gravity data imply up to 3 km of crustal thickening under the 19°E axis-perpendicular ridge. The 19°E magmatic center may result from interaction of the ridge with a passively imbedded mantle inhomogeneity. Away from 19°E, the crust appears thin and patchy and may consist of basalt directly over peridotite. The ridge axis is continuous with no transform offsets. However, sections of the ridge have distinctly different linear trends. Changes in ridge trend at 32°E and 63°E are associated with a set of bathymetric features that are very similar to each other and to inside/outside corner complexes observed at the MAR including high-standing ‘‘inside corner’’ ridges, which gravity data show to be of tectonic rather than magmatic origin.

description: The surface alignment of lyotropic chromonic liquid crystals (LCLCs) can be not only planar (tangential) but also homeotropic, with self-assembled aggregates perpendicular to the substrate, as demonstrated by mapping optical retardation and by three-dimensional imaging of the director field. With time, the homeotropic nematic undergoes a transition into a tangential state. The anchoring transition is discontinuous and can be described by a double-well anchoring potential with two minima corresponding to tangential and homeotropic orientation.

description: Chemical functionalization of graphene modifies the local electron density of the carbon atoms and hence electron transport. Measuring these changes allows for a closer understanding of the chemical interaction and the influence of functionalization on the graphene lattice. However, not only chemistry, in this case diazonium chemistry, has an effect on the electron transport. Latter is also influenced by defects and dopants resulting from different processing steps. Here, we show that solvents used in the chemical reaction process change the transport properties. In more detail, the investigated combination of isopropanol and heating treatment reduces the doping concentration and significantly increases the mobility of graphene. Furthermore, the isopropanol treatment alone increases the concentration of dopants and introduces an asymmetry between electron and hole transport which might be difficult to distinguish from the effect of functionalization. The results shown in this work demand a closer look on the influence of solvents used for chemical modification in order to understand their influence.
State Estimation for Human Motion and Humanoid Locomotion

description: The future where the industrial shop-floors witness humans and robots working in unison and the domestic households becoming a shared space for both these agents is not very far.
The scientific community has been accelerating towards that future by extending their research efforts in human-robot interaction towards human-robot collaboration.
It is possible that the anthropomorphic nature of the humanoid robots could deem the most suitable for such collaborations in semi-structured, human-centered environments.
Wearable sensing technologies for human agents and efficient human-aware control strategies for the humanoid robot will be key in achieving a seamless human-humanoid collaboration.
This is where reliable state estimation strategies become crucial in making sense of the information coming from multiple distributed sensors attached to the human and those on the robot to augment the feedback controllers designed for the humanoid robot to aid their human counterparts.

In this context, this thesis investigates the theory of Lie groups for designing state estimation techniques aimed towards humanoid locomotion and human motion estimation.
The abstract nature of Lie theory provides a unified approach to handle the three-dimensional machinery and the complex geometry required for modeling free-floating, highly articulated multi-body systems.
It enables suitably appropriate methods to perform rigorous calculus over complex nonlinear spaces and to handle the notion of uncertainties in such spaces, which are important for an estimator design.

Methods for loosely-coupled and tightly-coupled sensor fusion for floating base estimation of a humanoid robot are presented through the theory of averaging and filtering on Lie groups.
The problem of human motion estimation through wearable sensing technologies is tackled through a combination of dynamical systems' theory-based Inverse Kinematics and filtering on Lie groups, demonstrated to be directly applicable also for humanoid state estimation.
Experimental validations of the estimators for humanoid base estimation and human motion estimation have been carried out on simulated datasets and datasets collected from real-world experiments conducted on the iCub humanoid robot and Xsens Motion capture technology, respectively.

description: We analyze a special class of 1-D quantum walks (QWs) realized using optical multi-ports. We assume non-perfect multi-ports showing errors in the connectivity, i.e. with a small probability the multi- ports can connect not to their nearest neighbor but to another multi-port at a fixed distance - we call this a jump. We study two cases of QW with jumps where multiple displacements can emerge at one timestep. The first case assumes time-correlated jumps (static disorder). In the second case, we choose the positions of jumps randomly in time (dynamic disorder). The probability distributions of position of the QW walker in both instances differ significantly: dynamic disorder leads to a Gaussian-like distribution, while for static disorder we find two distinct behaviors depending on the parity of jump size. In the case of even-sized jumps, the distribution exhibits a three-peak profile around the position of the initial excitation, whereas the probability distribution in the odd case follows a Laplace-like discrete distribution modulated by additional (exponential) peaks for long times. Finally, our numerical results indicate that by an appropriate mapping an universal functional behavior of the variance of the long-time probability distribution can be revealed with respect to the scaled average of jump size.

description: In this report we present two complex eruptive solar events and the associated Cosmic Ray effects (Forbush decrease). We use combined recordings from a number of Earthbound Receivers, Space Experiments and data archives (such as the ARTEMIS-IV Radio spectrograph, the Athens NEUTRON MONITOR, the LASCO CME Lists, the SONG of the {CORONAS-F} satellite, etc.). The influence of solar transients on the interplanetary medium conditions and the cosmic ray flux is analysed and discussed. The observed time sequence of events of this time period indicates that the initiation of CMEs is closely related to the appearance of type II and IV radio bursts and strong solar flares. Their effects extend from the lower corona to the near Earth vicinity affecting Cosmic Ray measurements and space weather. As regards the Forbush decrease our data indicate significant amplification at the presence of a MHD shock.

description: First-principles dynamical CPA (Coherent-Potential Approximation) for electron correlations has been developed further by taking into account higher-order dynamical corrections with use of the asymptotic approximation. The theory is applied to the investigations of a systematic change of excitation spectra in $3d$ transition metals from Sc to Cu at finite temperatures. It is shown that the dynamical effects damp main peaks in the densities of states (DOS) obtained by the local density approximation to the density functional theory, reduce the band broadening due to thermal spin fluctuations, create the Mott-Hubbard type bands in the case of fcc Mn and fcc Fe, and create a small hump corresponding to the `6 eV' satellite in the case of Co, Ni, and Cu. Calculated DOS explain the X-ray photoelectron spectroscopy data as well as the bremsstrahlung isochromat spectroscopy data. Moreover, it is found that screening effects on the exchange energy parameters are significant for understanding the spectra in magnetic transition metals.
