description: The purpose of this article is to verify impact variables on international demand for beef between January 1995 and June 2013. The method used was Ordinary Least Squares with Breaks, obtaining 4 breaks, 5 regimes. The independent variables in the regression were the domestic and export prices of beef, chicken and pork, besides income and the exchange rate. In the first regime, the demand for beef was elastic with regard to prices, both internal and external, the domestic chicken and beef prices. However, income elasticity was more significant. In the second regime, the relation of export prices was inelastic. The income elasticity was significant in this regime and the exchange rate had a significant impact. In the third regime, the demand was inelastic to export prices of chicken and beef and inelastic to domestic prices of the same meat. The exchange rate also had a significant impact. In the fourth regime, the demand was elastic to its domestic price and inelastic in relation to external and internal prices of chicken. The income becomes significant again. In the fifth regime, demand is elastic to the external price of pork, domestic bovine price and income. There was a significant increase trend in the second regime and recession in the first and third regimes.

New start-up intermediaries: an institutional theory perspective
Creators: name: Vandeweghe, Laurens
Publisher: name: Imperial College London
Year: 2020

description: The present dissertation consists of three free-standing papers focused on the challenges that new start-up intermediaries face when spanning different social groups. The first paper advances theoretical understanding of the accelerator as an organizational form by drawing on a systematic literature review. We identify four distinct research orientations on the accelerator, highlight their common and divergent perspectives on the organizational features of the accelerator and synthesize them into an integrative typology. We contribute to our understanding of the theoretical underpinnings of the accelerator. The second paper inducts a model of a change in the instantiation of logics at an estranged hybrid by drawing on a longitudinal single case study analysis of a hybrid accelerator spanning the university, corporate, and professional software developer logics. We induct that internal agents enable such change by (1) renegotiating hybrid goals, (2) acquiring target logic, (3) acculturating into target logic and (4) embedding the new instantiation of logics. We further illuminate the different responses that individuals expose when engaging with changing institutional logics at estranged hybrids. The third paper explores how a concept gets translated into a recipient organization when the logics of the source context and the recipient context are mutually incompatible. Using ethnographic techniques, I conduct a longitudinal single case study analysis of a corporation that implemented the concept of impact investing. I find that the corporate motivations for implementing the concept gradually change as tensions surface, and that this leads the internal agents to morph the implemented concept from a strict coupling to a decoupling with the source concept.
A question of hierarchy: matter effects with atmospheric neutrinos and anti-neutrinos

description: It is by now established that neutrinos mix, have (different) non-zero masses, and therefore oscillate. The oscillation parameters themselves, however, are not all well-known. An open problem is that of the neutrino mass hierarchy. We study the possibility of determining the neutrino mass hierarchy with atmospheric neutrinos using an iron calorimeter detector capable of charge identification such as the proposed MONOLITH and ICAL/INO detectors. We find that such detectors are sensitive to the sign of the mass-squared difference, δ_{32} = m_3^2 - m_2^2, provided the as-yet unknown mixing angle between the first and third generations, θ_{13}, is greater than 6 degrees (\sin^2 2θ_{13} > 0.04). A result with a significance greater than 90% CL requires large exposures (more than 500 kton-years) as well as good energy and angular resolution of the detected muons (better than 15%), especially for small θ_{13}. Hence obtaining definitive results with such a detector is difficult, unless θ_{13} turns out to be large. In contrast, such detectors can establish a clear oscillation pattern in atmospheric neutrinos in about 150 kton-years, therefore determining the absolute value of δ_{32} and \sin^2 2 θ_{23} to within 10%.

description: This research analyzed the performance of the Uruguayan apple export chain for fresh consumption, through the so-called policy analysis matrix method (PAM). The selected variety was Royal Gala, which is becoming an important export product due its early maturity season and good acceptability in highincome markets, such as Europe.The study quantified the effects of public policies (taxes, subsidies and social security cost) and the potential market failures affecting the different rings of the production chain. The potential transfers from and towards the chain were estimated. First, all revenues and costs were computed for each ring: production, transportation, and packing. In the second stage, private and social benefits were estimated, from the farm level up to the port.The results showed that global profits generated during 2007 by the apple export chain reached 347.57 US dollars per metric ton of processed fruit. The private agents involved in this chain capture up to 90% of this value, leaving on the table 37.51 US dollars per metric ton, in terms of net transfers towards other sectors of the economy. In 2010, the global profits dropped to 251.15 US$/t. Private agents only captured 68% of this value, as net transfers attained 80.58 US$/t.
description: Este trabajo analizó el desempeño de la cadena exportadora de manzana para consumo en fresco, en Uruguay, mediante el método de la matriz de análisis de políticas (MAP). Se trabajó con la variedad Royal Gala, una de las más exportadas localmente por su temprana maduración y su buena aceptación en mercados de valor, como el europeo. Se cuantificaron los efectos de las políticas públicas (impuestos, subsidios, cargas sociales) y las eventuales fallas de mercado que afectan los distintos eslabones, estimándose las potenciales transferencias de recursos, desde o hacia la cadena. Primero se computaron los ingresos y costos en los distintos eslabones considerados: producción, transporte, procesamiento y empaque. Se calcularon los beneficios privados y sociales en toda la cadena, desde la chacra hasta el puerto. Los resultados mostraron un beneficio global de 347,57 US$/ton procesada para 2007. Los agentes privados involucrados en la cadena capturaron el 90% de este valor, dejando sobre la mesa 37,51 dólares por tonelada de manzana procesada, en forma de transferencias netas hacia otros sectores de la economía. En 2010, dicho beneficio disminuyó a 251,15 US$/ton. Los agentes privados se apropiaron del 68%, derivando en una transferencia neta de 80,58 US$/ton hacia el resto de la economía.
Design of a serialized link for on-chip global communication
Creators: name: Kedia, Amit
Publisher: name: University of British Columbia
Year: 2010

description: On-chip global communication is required for data and control transfers across various modules on the chip and determines the performance of the integrated circuit in current technology generation. A particularly difficult challenge at the present time is the routing complexity and congestion of parallel buses that span large distances on the chip. This thesis presents the design of an on-chip serialized link for replacing a parallel bus. The serial channel uses a wave-pipelined signaling scheme which provides high data rates to compensate for the loss of parallelism. A serializer-deserializer (SERDES) transceiver is investigated to determine the required number of wires in the serial channel based on interconnect bandwidth and design overhead. Further, the robustness of the SERDES technique is studied in the presence of on-chip variations. A technique for reducing the energy consumption on the serial channel by lowering the average switching activity is also proposed. Using our design technique, a 32-bit wide parallel bus operating at a frequency of 1Ghz in 90nm CMOS technology can be replaced by a serial channel consisting of 4 interconnects. Considering overhead due to the SERDES transceiver itself, the number of interconnects required in the serial channel increases to 8. Further, the intra-die variation forces the required number of interconnects to 16. This thesis also demonstrates that the energy of a serialized link can be reduced by up to 40% if there is prior knowledge of the data to be transmitted on the bus.
Constraints on relativistic beaming from estimators of the unbeamed flux

description: We review the statistical properties of relativistic Doppler boosting relevant for studies of relativistic jets from compact objects based on radio--X-ray(--mass) correlations, such as that found in black-hole X-ray binaries in the low/hard state, or the ``fundamental plane'' of Merloni, Heinz, & DiMatteo. We show that the presence of only moderate scatter in such relations does not necessarily imply low Lorentz factors of the jets producing the radio emission in the samples under consideration. Applying Doppler beaming statistics to a large sample of XRBs and AGN, we derive a limit on the width of the Lorentz factor distribution of black holes with relativistic jets: If the X-rays are unbeamed (e.g., if they originate in the accretion disk or in the slower, innermost part of the jet), the width of the βΓdistribution should be about one order of magnitude or less. If the scatter about the ``fundamental plane'' is entirely dominated by relativistic beaming, a lower limit on the mean Lorentz factor > 5 can be derived. On the other hand, if the X-rays are boosted by the same factor as the radio emission, we show that the observed scatter cannot be reasonably explained by Doppler boosting alone.

description: In small developing countries such as Uruguay, the potential economic benefits to be gained by the adoption of new agricultural technologies based on biotechnology are limited by a reduced productive base. This work assesses the potential economic impact of a herbicide-resistant transgenic rice variety, where the market power of the multinational firm owning the variety affects adoption rates through the monopoly margin exerted in the purchase price of the seed. We employ stochastic simulation methods to study outcome variations due to changes in the technological parameters and the adoption rates. Producer’s economic surplus averaged US$1.82 million, while the monopolistic gain is US$0.55 million. These relatively small economic profits suggest that, without public policy strategies for increasing the potential profits and reducing research costs, the multinational companies are not willing to invest significant resources for developing a transgenic variety adapted to local conditions. The alliances with national institutions and the access to expanded regional markets also contribute to increase the private incentives in R&D.

description: The objective of this research is to determine the impact of the CONEAT productivity index over farmland prices in Uruguay. The CONEAT index attempts to express the relationship between land productivity, measured in terms of meat and wool production, and the type of soil present in the land. The advantage of this index is that is easily understood by all agents operating in the agricultural sector. The main critic is that it considers exclusively parameters from livestock production, which may be questioned when applied to the comparison of land for other productive uses. In spite of this pitfall, the CONEAT index is widely used to value farmlands in Uruguay, as well as compare productivity among rural lands. In order to assess the implicit money values that land traders assign to CONEAT productivity index, a hedonic price model was estimated. This study analyzes 1,407 land transactions, representing almost 2 million hectares, carried out between December 1993 and January 2005. The findings reveal that the CONEAT index has a nonlinear positive relationship with the price per hectare. Along with productive aptitude, farm location, and market conditions, these are all relevant characteristics for farmland price formation in Uruguay.
description: El objetivo de la presente investigación es cuantificar el impacto del índice de productividad CONEAT sobre los precios pagados por los inmuebles rurales en el Uruguay. El índice CONEAT intenta expresar la relación entre la capacidad de producción de un predio, medida en términos de carne y lana, y las unidades de suelo que lo componen. La ventaja de su uso radica en su fácil comprensión por parte de los agentes. La principal crítica es que utiliza exclusivamente parámetros de producción ganadera que hacen cuestionable su uso cuando se comparan inmuebles con otras aptitudes productivas. Sin embargo, aun se lo utiliza frecuentemente para tasar inmuebles rurales o comparar productividad entre inmuebles. Para estimar el valor monetario implícito que los agentes asignan al índice CONEAT, se utilizó un modelo de precios hedónicos. Se analizó información correspondiente a 1.407 transacciones efectuadas entre diciembre de 1993 y abril del 2005, abarcando una superficie de 2 millones de hectáreas. El análisis revela que el índice CONEAT mantiene una relación positiva, no lineal, con el precio de la hectárea. Junto a la aptitud de uso, la localización y las condiciones de mercado, todas estas son características relevantes en la formación de precios de los campos uruguayos.

description: For more than 30 years, the Central Kiyú has been a reference for marketing Hereford purebred bulls in Uruguay. As a performance test center, it played a key role in incorporating objective information for marketing Hereford sires. The particular characteristics of Kiyú make of its auctions an excellent source for studying bulls' market behavior. In particular, this research assessed the economic value buyers assigned to this information, using a hedonic price model. The results from 11 years of auctions performed at Kiyú reveal that both sale order and sale weight were the most relevant variables in determining bull's sale prices. Other bull traits such as variety and eye pigmentation were also identified as important. Polled bulls received price premiums compared to horned or non-polled bulls, ceteris paribus. In addition, buyers preferred bulls with pigmented eyes rather than animals not having this condition. With regard to measures of genetic merit, sires reporting lower values for birth weight EPDs and higher values for weight at 18 months EPDs obtained better prices, other things equal, than sires that did not excel in those traits.
description: Durante más de treinta años, la Central Kiyú ha sido una referencia para la venta de toros Hereford en el Uruguay. Como Central de Pruebas, ha cumplido un rol fundamental en la incorporación de información objetiva sobre los reproductores comercializados. Las características particulares de Kiyú, hacen de sus remates una excelente fuente de estudio de la comercialización de reproductores de cabaña, para la raza. En particular, este trabajo cuantificó el valor económico que los compradores atribuyen a dicha información a través de un modelo de precios hedónicos. Los resultados provenientes de 11 años de remates revelan que el orden de entrada a pista y el peso de venta fueron las variables más relevantes en la determinación del precio de un toro. En igualdad de otras condiciones, los toros mochos recibieron mayores precios que los no mochos. Adicionalmente, los compradores mostraron inclinación por animales con buen grado de pigmentación en los ojos frente a los que no presentaron esa condición, lo cual se tradujo en premios en el precio. En cuanto al mérito genético, el estudio demostró que los compradores valoraron más a toros con bajos valores de EPD para peso al nacer y altos valores de peso a los 18 meses.

description: We revisit and complete the study of curved BPS-domain walls in matter-coupled 5D, N=2 supergravity and carefully analyse the relation to gravitational theories known as "fake supergravities". We first show that \emph{curved} BPS-domain walls require the presence of non-trivial hypermultiplet scalars, whereas walls that are solely supported by vector multiplet scalars are necessarily \emph{flat}, due to the constraints from very special geometry. We then recover fake supergravity as the effective description of true supergravity where one restricts the attention to the flowing scalar field of a given BPS-domain wall. In general, however, true supergravity can be simulated by fake supergravity at most \emph{locally}, based upon two choices: (i) a suitable adapted coordinate system on the scalar manifold, such that only one scalar field plays a dynamical role, and (ii) a gauge fixing of the SU(2) connection on the quaternionic-Kahler manifold, as this connection does not fit the simple formalism of fake supergravity. Employing these gauge and coordinate choices, the BPS-equations for both vector and hypermultiplet scalars become identical to the fake supergravity equations, once the line of flow is determined by the full supergravity equations.

description: Cattle market can be viewed as a differentiated market, where quality is determined by a set of attributes that completely define the product. There exist price differentials (premiums and discounts) that depend on the specific characteristics of cattle. Market monetary values of the characteristics of interest were estimated using a hedonic price model, involving more than 8,000 lots (454 thousand heads) traded at cattle video auctions. Most of the variables included in the auction catalogs influenced short-time market prices. Nonlinear relationships and interactions among some of the characteristics were also verified. Marketing strategies, such as lot size, order, scale-determined weight, and outstanding lot recommendations, were also relevant in price determination, as well as market conditions measured by season of the sale and current market price levels. Finally, it seems worthy some additional efforts to improve recording of some presumably important characteristics such as presence of horns and health traits, which could not been used in the present research.

A través de un modelo de precios hedónicos se estimó el valor monetario que el mercado otorga a dichas características, medidas sobre más de 8.000 lotes (454 mil vacunos) comercializados por pantalla. La mayoría de las variables incluidas en los catálogos incidieron en la formación de los precios. Peso, sexo, raza, clase, estado, procedencia, uniformidad, tratamiento nutricional y conocimiento del mío-mío, son características que afectaron significativamente el precio. Varias de estas variables mostraron relaciones no lineales o interacciones entre sí. Estrategias de mercadeo como el tamaño de lote, orden de entrada al remate, determinación del peso en balanza, recomendación explícita de lotes destacados, son también importantes en la determinación del precio, así como las condiciones imperantes en el mercado, como la época del año o el nivel general de los precios. Finalmente, vale la pena hacer el esfuerzo de registrar mejor algunas características como ser la presencia de astas y el manejo sanitario, las que no pudieron ser incluidas en el análisis.

description: Agricultural production is highly exposed to potential negative effects derived from a set of highly variable factors. Weather, biological, institutional, human, and market factors affect yields as well as input and product prices. These factors are responsible for the economic risk any firm must face, regardless how it is financed; they can cause huge losses in a short period of time. On the other hand, financial risk to the often uncertain possibility that farmers could not bear their financial obligations (payments of interests and principal), which may affect viability of the firm. Both economic and financial risks are intimately linked, since the feasibility of dealing with its financial obligations greatly depends upon the productive ability of the firm. Two complementary easy-to-apply commonly used methods for estimation of economic and financial risks are presented in this study. The first method analyzes the variability of both Return on Assets (ROA) and Return on Equity (ROE) measured within the firm through historical information. The second method analyzes the structure of costs and the financial structure of the firm, measured through the economic and the financial leverages, respectively.
description: La producción agropecuaria está muy expuesta a los posibles efectos negativos de una serie de factores que presentan un muy alto grado de variabilidad. Factores climáticos, biológicos, institucionales, humanos y de mercados, afectan rendimientos y precios de productos e insumos. Estos factores son responsables del riesgo económico al que toda empresa está expuesta – cualquiera sea la forma en que se financie – y que puede originar grandes pérdidas en poco tiempo. Por otro lado, el riesgo financiero refiere a la posibilidad, incierta muchas veces, que el productor no pueda hacer frente a sus obligaciones financieras (pago de intereses y amortización de deudas), lo cual puede afectar la misma viabilidad de la empresa. Ambos riesgos están íntimamente ligados, ya que la posibilidad de hacer frente a las obligaciones financieras depende en gran medida de la capacidad productiva de la empresa. En este trabajo se presentan dos métodos, de fácil aplicación, para la estimación del riesgo económico y financiero, cuyos enfoques son complementaros. El primer método analiza la variabilidad de la rentabilidad económica y financiera de la empresa, a partir de información histórica. El segundo, analiza la estructura de costos y la estructura financiera, a través del grado de apalancamiento económico y financiero.

description: On the grounds of a Feynman-Kac--type formula for Hamiltonian lattice systems we derive analytical expressions for the matrix elements of the evolution operator. These expressions are valid at long times when a central limit theorem applies. As a remarkable result we find that the ground-state energy as well as all the correlation functions in the ground state are determined semi-analytically by solving a simple scalar equation. Furthermore, explicit solutions of this equation are obtained in the noninteracting case.

description: The present study looks for better understanding the demand for beef products in Montevideo, considering three geographic areas representing different socioeconomic levels, through the observed supply at the two most important retail formats: supermarkets and meat stores. Twenty one percent of the total volume was traded in the high- socioeconomic level area (AG1), 47% was traded in the mid-socioeconomic level (AG2) while the remaining 32% was traded in the low-socioeconomic level area (AG3). The results of this research showed that as we move from areas of high to low socioeconomic levels in Montevideo, the demand for cheaper cuts (chuck, clod, navel, and rib plate) increased in comparison to more valuable cuts (tenderloin, inside and eye round). Additionally, it was observed that meat stores (butcheries) exhibited their offered products mainly inside window cases (bulky rather than packed in vacuum bags or trays). Although it seems that supermarkets had better interpreted changing consumption habits and tastes, meat stores started adopting marketing strategies for capturing clients, going from improvements in packing and product presentation to incorporating other kind of products to their supply.

Los resultados obtenidos mostraron que a medida que disminuía el nivel socioeconómico de los consumidores aumentaba la demanda por cortes más económicos (aguja, paleta, falda y asado) en comparación con los más valiosos (lomo, nalga y peceto). Independientemente, se observó que las carnicerías ofertaban sus productos casi exclusivamente en vitrinas (mayoritariamente cortes sueltos frente cortes al vacío o bandejas). Si bien los supermercados han interpretado mejor (o inducido) los cambios en los hábitos de los consumidores las carnicerías han comenzado a adoptar estrategias para aumentar la captación de clientes, que van desde mejoras en la presentación y exposición de los productos hasta la incorporación de productos anexos a su oferta comercial.

description: A substantial fraction of barred galaxies host additional nuclear bars which tumble with pattern speeds exceeding those of the large-scale (primary) stellar bars. We have investigated the mechanism of formation and dynamical decoupling in such nested bars which include gaseous (secondary) nuclear bars within the full size galactic disks, hosting a double inner Lindblad resonance. Becoming increasingly massive and self-gravitating, the nuclear bars lose internal (circulation) angular momentum to the primary bars and increase their strength. Developing chaos within these bars triggers a rapid gas collapse -- bar contraction. During this time period, the secondary bar pattern speed Omega_s~a^{-1}, where "a" stands for the bar size. As a result, Omega_s increases dramatically until a new equilibrium is reached (if at all), while the gas specific angular momentum decreases -- demonstrating the dynamical decoupling of nested bars. Viscosity, and therefore the gas presence, appears to be a necessary condition for the prograde decoupling of nested bars. This process maintains an inflow rate of ~1 M_o/yr over ~10^8 yrs across the central 200 pc and has important implications for fueling the nuclear starbursts and AGN.

description: Globular clusters (GCs) formed when the Milky Way experienced a phase of rapid assembly. We use the wealth of information contained in the Galactic GC population to quantify the properties of the satellite galaxies from which the Milky Way assembled. To achieve this, we train an artificial neural network on the E-MOSAICS cosmological simulations of the co-formation and co-evolution of GCs and their host galaxies. The network uses the ages, metallicities, and orbital properties of GCs that formed in the same progenitor galaxies to predict the stellar masses and accretion redshifts of these progenitors. We apply the network to Galactic GCs associated with five progenitors: {\it Gaia}-Enceladus, the Helmi streams, Sequoia, Sagittarius, and the recently discovered, `low-energy' GCs, which provide an excellent match to the predicted properties of the enigmatic galaxy `Kraken'. The five galaxies cover a narrow stellar mass range [$M_\star=(0.6{-}4.6)\times10^8~{\rm M}_\odot$], but have widely different accretion redshifts ($z_{\rm acc}=0.57{-}2.65$). All accretion events represent minor mergers, but Kraken likely represents the most major merger ever experienced by the Milky Way, with stellar and virial mass ratios of $r_{M_\star}=1$:$31^{+34}_{-16}$ and $r_{M_{\rm h}}=1$:$7^{+4}_{-2}$, respectively. The progenitors match the $z=0$ relation between GC number and halo virial mass, but have elevated specific frequencies, suggesting an evolution with redshift. Even though these progenitors likely were the Milky Way's most massive accretion events, they contributed a total mass of only $\log{(M_{\rm \star,tot}/{\rm M}_\odot)}=9.0\pm0.1$, similar to the stellar halo. This implies that the Milky Way grew its stellar mass mostly by in-situ star formation. We conclude by organising these accretion events into the most detailed reconstruction to date of the Milky Way's merger tree.

description: The Blonder-Tinkham-Klapwijk model of the Point-Contact Andreev Reflection spectroscopy does not provide an adequate description of experiment in the presence of magnetic field. We demonstrate this using a junction between a niobium tip and a copper film. We modify the the-ory to explicitly take into account the contribution to conductance that stems from the normal vortex cores in the superconductor. These results have important implications for interpretation of transport spin polarisation measurements using PCAR technique. We demonstrate that stray magnetic fields can be responsible for the experimentally observed dependence of the spin po-larisation on the strength of the interface barrier, and potential misassignment of the inferred spin polarisation.

description: The SUPERSHINE project is a comprehensive initiative designed to address the urgent need forenergy efficiency renovations across Europe. Focused on Italy, Latvia, and Denmark, this projectemploys financial and statistical analyses within the framework of Public-Private Partnerships (PPPs)and crowdfunding to facilitate energy efficiency projects and foster sustainable development. Thisdocument covers the following:Environmental and Social impact analysis:This section focuses on the environmental impact assessment of district retrofit interventions inItaly, Latvia, and Denmark. These interventions aim to improve energy performance, reduce carbonemissions, and promote sustainable practices. The methodology involves evaluating the energysavings potential, assessing related costs, and emphasising waste management strategies, such asutilising local agricultural waste and promoting recycling. Despite substantial upfront costs, thelong-term benefits, coupled with potential carbon credits and voluntary carbon market support,make these interventions economically viable and environmentally sustainable. Through rigorousenvironmental assessment and mitigation strategies, SUPERSHINE seeks to drive positiveenvironmental outcomes and contribute to the transition towards a more sustainable future.The document outlines the methodology employed, starting with the energy savings modellingprocess. This involves data collection, baseline assessment, intervention simulation, and resultanalysis to predict energy consumption reductions and CO2 emissions reductions post-renovation.Energy efficiency and renewable measures can yield numerous substantial social ramificationsbeyond their immediate effects on energy efficiency and cost. Frequently, these implications aredisregarded due to the challenge of quantifying their value. The section related with social impactemphasises this aspect of the measures.

description: Motivated by nuclear safety issues, we study the heat transfers in a thin cylindrical fluid layer with imposed fluxes at the bottom and top surfaces (not necessarily equal) and a fixed temperature on the sides. We combine direct numerical simulations and a theoretical approach to derive scaling laws for the mean temperature and for the temperature difference between the top and bottom of the system. We find two asymptotic scaling laws depending on the flux ratio between the upper and lower boundaries. The first one is controlled by heat transfer to the side, for which we recover scaling laws characteristic of natural convection. The second one is driven by vertical heat transfers analogous to Rayleigh Benard convection. We show that the system is inherently inhomogeneous, and that the heat transfer results from a superposition of both asymptotic regimes. Keeping in mind nuclear safety models, we also derive a one-dimensional model of the radial temperature profile based on a detailed analysis of the flow structure, hence providing a way to relate this profile to the imposed boundary conditions.

The use of a magnetic model to analyze the load dependent behaviour of a power supply

description: It has been known since the first half of the 1990s that power supplies based on the ferroresonant transformer technology are incompatible with certain more recent types of loads such as actively power factor corrected devices. This is an issue that still remains today. The objective of this thesis is to analyze whether a specific ferroresonant uninterruptible power supply, operating in line mode, can be controlled by a linear time-invariant controller. This work shows that whether the ferroresonant-based circuit can be compatible with the aforementioned type of load is dependent on the characteristics of the same. The study includes a comprehensive nonlinear model of the controlled ferroresonant transformer also known as the controlled constant voltage transformer. Saturation is a normal mode of operation for this device. The level of detail includes winding resistances, core resistances, continuously nonlinear magnetizing inductances, tapped windings, and leakage inductances. A complete nonlinear state-space model of the power supply where the constant voltage transformer constitutes the major part is derived. The investigation encompasses stability evaluation of the device with several types of loads using a generalized approach. For the analysis, the nonlinear system is converted into a linearized periodically time-varying system, which in turn is sampled by means of Poincaré mapping to provide a discrete-time representation of the model. An analytical approach explains, in the discrete-time domain, why certain loads may be impossible to control by a linear time-invariant controller. The study emphasizes this type of controller since in general, with unknown loads, the assumption is that the controller should be relatively simple and less dependent on specific load parameters or specific type of loads. To complement the theory, this work also proposes an approximate procedure that leads to an implementation of a practical feedback controller that stabilizes a specific actively power factor corrected load. Laboratory experiments show that, for line mode operation, the power supply can indeed be compatible with the aforementioned load.
