Abstract:

The microstructures and mechanical properties of cold upsetting magnesium alloys were investigated upon anneal under different conditions. The results show that a large amount of twins were observed in the original grains of cold upsetting AZ31 magnesium alloys. The twins disappeared gradually and recrystal grains formed after anneal. The volume fraction of the recrystal grains increases as the strain of samples rises. Recrystal grain size grows large with the elevated annealing temperature. Recrystal grain size reduces at first and then grows as the annealing time is prolonged. In addition, compared with as-cast magnesium alloys, the yield strength of cold upsetting samples increase apparently due to grain refinement after anneals.

Abstract:

We have recently explored the nature and stability of native defects in high-purity semi-insulating 4H-SiC bulk substrates grown by PVT and HTCVD methods after post-growth anneal treatments up to 2400oC using electron paramagnetic resonance (EPR) and low-temperature photoluminescence (PL) experiments. In the present study we have extended these investigations to SI 4H-SiC subjected to the same post-growth high-temperature anneal treatments, where significantly enhanced carrier lifetimes have been reported for such conditions, but cooled at different rates ranging from ~2-25oC/min. Previously, the intensities of the native defects decreased monotonically with anneals from 1200–1800oC; however, it was recently observed that several of these defects reappear after annealing at 2100oC and above. Our results illustrate the effects of the post-growth anneal treatments and cool-down rates on the concentrations of native defects.

Abstract:

Oxygen precipitation (OP) behaviors in conventional and nitrogen co-doped heavily arsenic-doped Czocharalski silicon crystals subjected to low-high two-step anneals of 650 oC/8 h + 1000 oC/4-256 h have been comparatively investigated. Due to the nitrogen enhanced nucleation of OP during the low temperature anneal, much higher density of oxygen precipitates generated in the nitrogen co-doped specimens. With the extension of high temperature anneal, Oswald ripening of OP in the nitrogen co-doped specimens preceded that in the conventional ones. Moreover, due to the Oswald ripening effect, the oxygen precipitates in the conventional specimens became larger with a wider range of sizes. While, the sizes of oxygen precipitates in the nitrogen co-doped specimens distributed in a much narrower range with respect to the conventional ones.

Abstract:

An important aspect in the consideration of V-4%Ti-4%Cr alloys as structural materials for proposed fusion reactors, especially for weldments, is the sensitivity of mechanical behavior to oxygen content. Following a 1-h anneal at 1200°C, sheet specimens were subjected to extended (16h to 43h) anneals at 500°C in 5 to 8 x 10-6 torr oxygen, followed by an homogenization vacuum anneal of 100 h at 600°C. Weight gains indicated ∼200 to >1400 wppm oxygen doping. Specimens were also subjected to an additional vacuum anneal for 4 h at 950°C. Specimens were prepared by standard double-jet electropolishing for TEM characterization with a Philips CM30 (LaB6) equipped with a Gatan Imaging Filter (GIF), and with a Philips CM200FEG equipped with Oxford EDS, GIF, and Emispec Vision integrated acquisition system.Following oxygen doping and homogenization, high concentrations of nanoscale G.P.-zone-like clusters on ﹛001﹜ were observed in the matrix, with a ∼200-nm-wide precipitate free zone (PFZ) at grain boundaries.

Abstract:

ABSTRACTAs advanced CMOS scaling with FinFETs continues beyond the 10/7nm nodes, contact resistance (Rc) remains a dominant component affecting device performance. The FinFET Source/Drain (S/D) contact area has become smaller with fin pitch scaling, resulting in drastically increased Rc. To achieve higher drive currents and fully realize the performance gain from FinFET architectural changes, it is critical to continue to reduce contact resistivity (ρc) < 1.0x10-9 Ω.cm2 for both NMOS and PMOS. In this paper, we review the recent trends for ρc reduction for advanced CMOS devices and discuss approaches that have demonstrated reduction in ρc, such as in-situ heavily doped epitaxial films for S/D, advanced ion implantation and laser anneals. The implant techniques include pre-amorphization implants (PAI), dopant boosting implants, cryogenic (-100°C) implants for damage engineering and plasma doping (PLAD) for conformal doping of high aspect ratio (HAR) contacts. With such high levels of doping from epi and implants, advanced laser anneals are key for epitaxial regrowth and formation of metastable alloys for dopant supersaturation or segregation in top layers. Millisecond laser anneal (MSA) improves dopant activation and nanosecond laser anneal (NLA) permits superactivation, and both have become key enablers for ρc reduction. This paper also reviews two alternative contact approaches: dual silicide scheme and wrap-around contact (WAC), as potential pathways to further reduce Rc for advanced CMOS nodes.

Abstract:

This study focuses on the evaluation of different post-trench processes (PTPs) for Trench-MOSFETs. Thereto, two different types of inert gas anneals at process temperatures above 1250 °C are compared to a sacrificial oxidation as PTP. The fabricated 4H-SiC Trench-MOS structures feature a thick silicon dioxide (SiO2) both at the wafer surface (‘top’) and in the bottom of the trenches (‘bottom’) in order to characterize only the thin gate oxide at the trenched sidewalls. It is shown that an inert gas anneal at a process temperature between 1400 °C and 1550 °C yields uniform current/electric field strength (IE) values and excellent dielectric breakdown field strengths up to 12 MV/cm using a SiO2 gate oxide of approximately 40 nm thickness. Charge-to-breakdown (QBD) measurements at a temperature T of 200 °C confirm the necessity of a high temperature inert gas anneal after 4H-SiC trench etching in order to fabricate reliable Trench-MOS devices. QBD values up to 16.2 C/cm² have been measured at trenched and high temperature annealed sidewalls, which is about twice the measured maximum QBD value of the corresponding planar reference MOS structure. The capacitive MOS interface characterization points out the need for a sacrificial oxidation subsequent to a high temperature inert gas anneal in order to ensure a high quality MOS interface with excellent electrical properties.

Abstract:

Selon la version de Green-Matignon de la conjecture de F. Oort, toute série d'ordre pn peut être relevée en une série de même ordre dont les coefficients sont entiers sur une extension convenable de Qp. Il est donc nécessaire de relever une série de chaque classe de conjugaison pour pouvoir relever l'ensemble des séries formelles d'ordre pn. C'est pourquoi, nous avons étudier dans ce travail les classes de conjugaison des séries d'ordre pn à coefficients dans la clôture algébrique Fpalg de Fp. Le premier chapitre est consacré aux rappels concernant les corps locaux et en particulier sur les corps locaux de caractéristique p. Dans le deuxième chapitre, nous donnons une démonstration au théorème de B. Klopsch qui donne les classes de conjugaison des séries d'ordre p dans le cas où le corps résiduel est parfait. Le troisième chapitre est dédié aux vecteurs de Witt et donne une réduction possible de ses vecteurs. Puis, dans le quatrième chapitre, nous utilisons les vecteurs de Witt de longueur n qui, grâce à la théorie d'Artin-Schreier-Witt déterminent les extensions de corps de degré pn. Dans le cinquième chapitre, nous utilisons l'équivalence entre endomorphismes et séries pour construire la première bijection établie entre un ensemble An de vecteurs de Witt et une caractérisation des extensions de degré pn de K. La seconde bijection permet, grâce à une certaine action de groupe, d'établir une correspondance entre les classes de conjugaison d'ordre pn et les orbites de An sous cette action. C'est ce que nous établissons dans le chapitre six. Pour finir, dans le dernier chapitre, nous donnons deux calculs, l'un utilisant la théorie de Lubin-Tate et l'autre la théorie d'Artin-Schreier-Witt, permettant d'obtenir une écriture explicite de séries d'ordre 4 pour la conjugaison
According to Green-Matignon's version of the conjecture of F. Oort, any series of order pn can be lifted up by a série of the same order which coefficients are integer in a certain extension of Qp. So it is necessary to lift a series of every conjugacy class to lift all formal power series of order pn. That is why, we have studied, in this report, conjugacy classes of formal power series of order pn with coefficients in the algebraic closure Fpalg de Fp. The first chapter is dedicated to recalls on locals fields and especially local fields of characteristc p. In the second chapter, we give a second proof of the theorem of B. Klopsch which states the conjugacy classes of series of order p when the residue field is perfect. The third chapter is dedicated to Witt vectors and gives a reduction of these vectors. Then, in the fourth chapter, we use Witt vectors of length n which, thanks to Artin-Schreier-Witt theory, determined any extensions of degree pn. In the fifth chapter, we use the equivalence between endomorphisms and formal power series to construct the first bijection which states a link between a set An of Witt vectors and a certain characterization of extension of degree pn of K. The second bijection permits, thanks to a certain action of group to get a correspondence between conjugacy classes of order pn and the orbits of An under this action. This is this bijection we will build in the sixth chapter. Finally, in the last chapter, we give two calculations, the first one using the Lubin-Tate theory and the second one Artin-Schreier-Witt theory, to get an explicit writting of series of order 4 for he conjugation law

Abstract:

Due to their increasing complexity, today’s computer systems are studied using multiple models and formalisms. Thus, it is necessary to develop theories that unify different approaches in order to limit the risks of errors when moving from one formalism to another. It is in this context that monoids, semirings and Kleene algebras with domain were born about a decade ago. The idea is to define a domain operator on classical algebraic structures, in order to unify algebra and the classical logics of programs. The question of completeness for these algebras is still open. It constitutes the object of this thesis. We define tree structures called trees with a top and represented in matrix form. After having given fundamental properties of these trees, we define relations that make it possible to compare them. Then, we show that, modulo a certain equivalence relation, the set of trees with a top is provided with a monoid with domain structure. This result makes it possible to define a model for semirings with domain and prove its completeness. We also define a model for -continuous Kleene algebras with domain as well and prove its completeness modulo a new axiom.

Abstract:

L'espace de modules Mgbar des courbes stables de genre g est un object central en géométrie algébrique. Du point de vue de la géométrie birationelle, il apparaît naturel se demander si Mgbar est de type générale. Harris-Mumford et Eisenbud-Harris ont montré que Mgbar est de type générale pour un genre g>=24 et g=22. Le cas g=23 est encore misterieux. Dans les dix dernières années une nouvelle approche a émergé, dans l'essai de clarifier ça : l'idée est celle de considérer de recouvrement fini de Mgbar qui sont des espaces de modules de courbes stables munies d'une structure additionnelle comme un l-recouvrement (racine l-ième du fibré trivial) ou un fibré l-spin (racine l-ième du fibré canonique). Ces espaces ont la propriété que la transition au type générale se produit à un genre inférieur. Dans ce travail nous voulons généraliser cette approche de deux façons : - un étude de l'espace de modules des courbes avec une racine d'une puissance quelconque du fibré canonique ; - un étude de l'espace de modules des courbes avec un G-recouvrement pour un quelconque G groupe fini. Pour définir ces espaces de modules nous utilisons la notion de courbe twisted (voir Abramovich-Corti-Vistoli). Le résultat fondamental obtenu est qu'il est possible de décrire le lieu singulier de ces espaces de modules par la notion de graphe dual d'une courbe. Grace à cette analyse, nous pouvons developper des calculs dans l'anneau tautologique des espaces, et en particulier nous conjecturons que l'espace de modules des courbes avec un S3-recouvrement est de type générale pour genre impaire g>=13
The moduli space Mgbar of genus g stable curves is a central object in algebraic geometry. From the point of view of birational geometry, it is natural to ask if Mgbar is of general type. Harris-Mumford and Eisenbud-Harris found that Mgbar is of general type for genus g>=24 and g=22. The case g=23 keep being mysterious. In the last decade, in an attempt to clarify this, a new approach emerged: the idea is to consider finite covers of Mgbar that are moduli spaces of stable curves equipped with additional structure as l-covers (l-th roots of the trivial bundle) or l-spin bundles (l-th roots of the canonical bundle). These spaces have the property that the transition to general type happens to a lower genus. In this work we intend to generalize this approach in two ways: - a study of moduli space of curves with any root of any power of the canonical bundle; - a study of the moduli space of curves with G-covers for any finite group G. In order to define these moduli spaces we use the notion of twisted curve (see Abramovich-Corti-Vistoli). The fundamental result obtained is that it is possible to describe the singular locus of these moduli spaces via the notion of dual graph of a curve. Thanks to this analysis, we are able to develop calculations on the tautological rings of the spaces, and in particular we conjecture that the moduli space of curves with S3-covers is of general type for odd genus g>=13

Abstract:

This thesis introduce my work on transverse and longitudinal non linear dynamics of an electron beam in ThomX, a novel X-ray source based on Compton backscattering. In this work I implemented in simulation code theoretical models to calculate transverse and longitudinal non linear dynamics under Compton back scattering. The processes studied include collective effect such as longitudinal space charge, resistive wall and coherent synchrotron radiation, intra beam scattering. I also implemented a longitudinal feedback algorithm and studied the effect of the feedback's delay in the simulation to explore its effects on beam dynamics. This code allows to perform a full 6D simulation of the beam dynamics in a ring under Compton back scattering taking into account the feedback stabilisation for the 400 000 turns (~ 20 ms) of one injection cycle. One important feature is that this simulation code can be run on a computer farm. Using this code I investigated the electrons dynamics in ThomX and the flux of scattered Compton photons. I analysed the relative contribution of each physical phenomena to the overall beam dynamics and how to mitigate their disruptive effect. As part of my work on longitudinal phase feedback I also measured and analysed properties of the ELETTRA RF cavity to be used on ThomX.

Abstract:

L'objectif de ce travail est le développement de couches catalytiques ordonnées en trois dimensions possédant une architecture contrôlée pour une application en pile à combustible et l’étude des propriétés electrocatalytiques de ces couches vis à vis de la réduction de l'oxygène, l'oxydation de l'hydrogène et de l'oxydation du monoxyde de carbone. Ce travail a été abordé par la préparation de couches catalytiques à base de nanoparticules du Pt déposées sur des nanofilaments de carbone verticalement alignés (Pt/VACNF). Ces couches catalytiques ont été considérées à la fois comme système modèle pour l'étude de la cinétique de réactions électrochimiques complexes et comme un système nouveau possédant des propriétés intéressantes en vue d'une 'utilisation dans les piles à combustible. La croissance des couches de VACNF a été effectuée à l'aide d'uneméthode de dépôt chimique en phase vapeur à partir d'un mélange de toluène et d'un catalyseur leferrocène. Les VACNF ainsi obtenues ont servi de substrat pour le dépôt de Pt en utilisant diverses méthodes chimiques et électrochimiques. Les couches Pt/VACNF ont été caractérisées parpar différentes techniques physiques (MET, MEB) et électrochimiques (CV). Afin de mieux comprendre les interactions entre la cinétique de réaction et les phénomènes de transport dans ces nouvelles architectures catalytique spatiallement ordonnées, nous avons étudié dans un premier temps les performances electrocatalytiques de ces couches vis à vis de l'oxydation de l'hydrogène, la réduction de l'oxygène et la réaction d'oxydation du CO en électrolyte liquide en utilisant une électrode à disque tournant et une électrode disque-anneau et comparé les résulats avec une modélisation mathématique de l'activité de ces nouvelles couches catalytiques. Ces études nous ont permis de comprendre l'influence des paramètres structuraux de ces couches catalytiques tels que l'épaisseur de la couche catalytique et le taux de couverture en Pt sur les nanofilaments sur leurs performances, le facteur d'efficacité d'utilisation du platine, ainsi que sur des réactions ayant une cinétique non-linéaire bistable (réaction d’oxydation du CO). Enfin, une nouvelle approche a été développée pour la préparation d'assemblage membraneélectrodes à base de VACNF sans perte de l'alignement. Ce travail a consisté dans la mise au point une procédure de croissance des VACNF et de dépôt de Pt sur des substrats de grandes dimensions dans le développement des méthodes de production d'assemblages membrane électrode non destructives
The aim of the present work is the development of novel 3D ordered catalytic layer architectures for fuel cell applications and their investigation in fuel cell related reactions such as oxygen reduction, hydrogen oxidation and CO oxidation reaction. This task is addressed via the preparation of catalytic layers based on Pt nanoparticles supported on vertically aligned carbon nano-filaments (Pt/VACNF). These catalytic layers were utilized both as a tool for gaining insights into the complex electrochemical reactions and as novel systems with promising activity for the use in PEM fuel cells. The growth of the arrays of the VACNF was performed using catalytic chemical vapor deposition from ferrocene/toluene mixture. Thus obtained systems were used as substrates for Pt deposition using various chemical and electrochemical methods. The obtained catalytic layers were investigated using a set of physical (TEM, SEM) and electrochemical (CV) tools. In order to get an insight into the complex interplay between the reaction kinetics and diffusion phenomena in these novel catalytic architectures we have currently chosen to study the hydrogen oxidation, the oxygen reduction and the CO oxidation reaction in liquid electrolyte using rotating disc and ring-disc methods coupled with mathematical modeling. These studies allowed understanding the influence of the key parameters such as the thickness of the catalytic layer and the Pt coverage on the performance of the catalytic layers, on the effectiveness of the Pt utilization as well as on bistable phenomena (as studied for dissolved CO oxidation). Finally, an approach has been developed for the incorporation of VACNF into MEA without loss of alignment. This work necessitated the scale-up of the growth procedure, Pt deposition, as well as required to establish the methods of a nondestructive membrane-electrode assembly production

Abstract:

De nombreux systèmes de transport peuvent être modélisées par des synchronisations ordinaires (pour tout k>=l, l'occurrence k de l'événement B se produit au moins t unités de temps après l'occurrence k-l de l'événement A). Ces systèmes sont linéaires dans l'algèbre (max,+). Pour certaines applications, il est primordial de modéliser la simultanéité entre événements. Comme la synchronisation ordinaire ne suffit pas à exprimer ce phénomène, nous introduisons la synchronisation partielle (l'événement B ne peut se produire que quand l'événement A se produit). Dans ce mémoire, des méthodes développées pour la modélisation et le contrôle de systèmes linéaires dans l'algèbre (max,+) sont étendues à des systèmes régis par des synchronisations ordinaires et partielles. Nous considérons uniquement des systèmes divisés en un système principal et un système secondaire et gouvernés par des synchronisations ordinaires entre événements dans le même système et des synchronisations partielles d'événements dans le système secondaire par des événements dans le système principal. Nous introduisons une commande optimale et une commande prédictive pour cette classe de systèmes par analogie avec les résultats disponibles pour les systèmes linéaires dans l'algèbre (max,+). En considérant un comportement donné pour le système principal, il est aussi possible de représenter le système secondaire par une fonction de transfert et de modifier sa dynamique pour suivre un modèle de référence
Many transportation networks can be modeled by (max,+)-linear systems, i.e., discrete event systems ruled by standard synchronizations (conditions of the form: "for all k>=l, occurrence k of event B is at least t units of time after occurrence k-l of event A"). In some applications, it is also necessary to model simultaneity between events (e.g., for a road equipped with traffic lights, a vehicle can cross an intersection only when the associated traffic light is green). Such conditions cannot be expressed using standard synchronizations. Hence, we introduce the partial synchronization (condition of the form: "event B can only occur when event A occurs"). In this thesis, we consider a class of discrete event systems ruled by standard and partial synchronizations, called (max,+)-systems with partial synchronization. Such systems are split into a main system and a secondary system such that there exist only standard synchronizations between events in the same system and partial synchronizations of events in the secondary system by events in the main system. We adapt some modeling and control approaches developed for (max,+)-linear systems to (max,+)-systems with partial synchronization. Optimal feedforward control and model predictive control for (max,+)-linear systems are extended to (max,+)-systems with partial synchronization. Furthermore, transfer relation and model reference control are provided for the secondary system under a predefined behavior of the main system

Abstract:

AbstractThis paper analyzes and contrasts the constraints, stakeholders, and framing goals that must be considered when Energy Master Planning (EMP) is conducted for communities in seven countries. The analysis is based on findings from seven countries participating in the International Energy Agency’s “Energy in Buildings and Communities Program Annex 73”. The analysis covers design constraints such as emissions, sustainability criteria, and resilience goals, regulations and directives, regional and local limitations, such as available energy types, local conditions, and various levels of stakeholders, as well as community objectives. An analysis of the various constraints on different planning levels was done, and the key stakeholders were identified. They can be characterized by different governance structures and thereby stakeholder constellations. Mapping of the stakeholders involved provides insights in further constraints resulting into issues within the EMP that will need to be addressed for multi-owner, multi-stakeholder neighborhoods and districts. With a closer look at a case study in Elverum, Norway, the paper identifies constraints related to stakeholders involved and their impact on applying EMP.

Abstract:

NORSOK U-001 4th edition was released October 1st, 2015. It replaces edition 3 from 2002. The 4th edition is based on industry experience and use of the previous version. With focus on Norwegian Continental Shelf (NCS) operations and experience, NORSOK U-001 provides normative reference and amendments to selected parts of ISO 13628 (equivalent to API 17 series). The focus areas of this paper are the informative annexes to NORSOK U-001: The revised Annex A (informative), and the new Annex B (informative). These annexes provide NCS related amendments to Part 4 (API 17D), Part 7 (API 17G), and Part 15 (API 17P) of ISO 13628. Annex A (informative) provides loads for design and selection of subsea trees, wellheads and templates and has been completely revised with new standard design loads. Annex B (informative) gives recommendations for structural design, manufacture and testing of subsea wellhead and tree equipment (ISO 13628-4/API 17D) and completion/workover riser systems (ISO 13628-7/API 17G). This paper provides a brief introduction and background to Annex A and Annex B. Some differences between NORSOK U-001 Annex B, ISO 13628-7 (API 17G), ISO 10423 (API 6A), API 6X, ISO 13628-4 (API 17D), ASME VIII Div. 3 and ASME VIII Div.2 are also highlighted.

Full text

Abstract:

Standards and Recommended Practices require periodic updating so they represent current technology and industry practices. Canadian Standards Association (CSA) Z662 “Oil and Gas Pipeline Systems” contains Annex E that covers software-based leak detection for liquid hydrocarbon pipelines. The CSA Technical Committee determined that is was time to update Annex E. A Task Force of industry experts and regulators met over a period of 18 month to draft a new Annex E. This paper outlines some of the significant features of the new Annex and where possible does a comparison with the similar section in American Petroleum Institute’s API 1130 which covers recommended practice for software based leak detection in the US. A pipeline operator should consider using both Annex E and API 1130 in the implementation and use of a software-based leak detection system. The CSA Task Force did not want to copy and modify API 1130 to provide a new Annex E, so both documents provide necessary information.

In ASME 2016 International Mechanical Engineering Congress and Exposition. American Society of Mechanical Engineers, 2016. http://dx.doi.org/10.1115/imece2016-65514.

Full text

Abstract:

The properties of carbon nanotubes are dependent, in part, on the size of the catalyst metal nanoparticles from which the carbon nanotubes are grown. Annealing is a common technique for forming the catalyst nanoparticles from deposited films. While there is ample work connecting catalyst film properties or catalyst nanoparticle properties to carbon nanotube growth outcomes, the control of catalyst nanoparticle size by means other than the variation of initial film thickness is less explored. This work develops an empirical correlation for the control of nickel nanoparticle equivalent diameter by modification of anneal plateau temperature and anneal plateau time, thereby providing an additional avenue of control for catalyst properties. It has been hypothesized that the size of catalyst nanoparticles can be predetermined by appropriate selection of the initial catalyst film thickness, plateau temperature, and plateau time of the annealing process. To this end, buffer layers of 50 nm titanium, followed by 20 nm aluminum, were deposited onto silicon substrates via electron beam evaporation. Nickel catalyst layers were then deposited with thicknesses of either 5, 10, or 20 nm. Samples of each of the three nickel layer thicknesses were annealed in an ambient air environment at different combinations of 500, 600, 700, 800, and 900 °C plateau temperature and 5, 10, and 15 minute plateau time. Representative time-temperature curves corresponding to each plateau temperature were also acquired. The end result was a set of 45 samples, each with a unique combination of initial nickel film thickness, anneal plateau temperature, and anneal plateau time. Resulting nanoparticles were characterized by atomic force microscopy, and distributions of nanoparticle equivalent diameter were collected via a watershed algorithm implemented by the Gwyddion software package. Comparison of the 45 parameter combinations revealed a wide range of nanoparticle sizes. In most cases, comparable equivalent diameters were obtained from a variety of parameter combinations. Thus, results provide multiple options for achieving the same nanoparticle diameter, for use in cases where additional restraints are present. To facilitate such decisions, a correlation was developed that connected catalyst nanoparticle diameter to the three process parameters of initial catalyst film thickness, anneal plateau temperature, and anneal plateau time. For example, a given initial Ni film thickness can be annealed to a specified nanoparticle size by selecting anneal plateau temperature and plateau time per the correlation, provided that comparable buffer layers were chosen. This correlation provides a more robust array of options for specification of catalyst nanoparticle size and final carbon nanotube properties for a specific application.

Full text

Abstract:

As 2020 draws to a close, the economic devastation caused by the COVID-19 pandemic shows no sign of abating. Without urgent action, global poverty and inequality will deepen dramatically. Hundreds of millions of people have already lost their jobs, gone further into debt or skipped meals for months. Research by Oxfam and Development Pathways shows that over 2 billion people have had no support from their governments in their time of need. Our analysis shows that none of the social protection support to those who are unemployed, elderly people, children and families provided in low- and middle-income countries has been adequate to meet basic needs. 41% of that government support was only a one-off payment and almost all government support has now stopped. Decades of social policy focused on tiny levels of means-tested support have left most countries completely unprepared for the COVID-19 economic crisis. Yet, countries such as South Africa and Bolivia have shown that a universal approach to social protection is affordable, and that it has a profound impact on reducing inequality and protecting those who need it most. In addition to the full paper and executive summary, an Excel file with the data analysed by Oxfam and Development Pathways is available to download on this page, along with an annex on the crisis in Latin America and the Caribbean.

Financial Stability Report - September 2015. Banco de la República, August 2021. http://dx.doi.org/10.32468/rept-estab-fin.sem2.eng-2015.

Full text

Abstract:

From this edition, the Financial Stability Report will have fewer pages with some changes in its structure. The purpose of this change is to present the most relevant facts of the financial system and their implications on the financial stability. This allows displaying the analysis more concisely and clearly, as it will focus on describing the evolution of the variables that have the greatest impact on the performance of the financial system, for estimating then the effect of a possible materialization of these risks on the financial health of the institutions. The changing dynamics of the risks faced by the financial system implies that the content of the Report adopts this new structure; therefore, some analyses and series that were regularly included will not necessarily be in each issue. However, the statistical annex that accompanies the publication of the Report will continue to present the series that were traditionally included, regardless of whether or not they are part of the content of the Report. In this way we expect to contribute in a more comprehensive way to the study and analysis of the stability of the Colombian financial system. Executive Summary During the first half of 2015, the main advanced economies showed a slow recovery on their growth, while emerging economies continued with their slowdown trend. Domestic demand in the United States allowed for stabilization on its average growth for the first half of the year, while other developed economies such as the United Kingdom, the euro zone, and Japan showed a more gradual recovery. On the other hand, the Chinese economy exhibited the lowest growth rate in five years, which has resulted in lower global dynamism. This has led to a fall in prices of the main export goods of some Latin American economies, especially oil, whose price has also responded to a larger global supply. The decrease in the terms of trade of the Latin American economies has had an impact on national income, domestic demand, and growth. This scenario has been reflected in increases in sovereign risk spreads, devaluations of stock indices, and depreciation of the exchange rates of most countries in the region. For Colombia, the fall in oil prices has also led to a decline in the terms of trade, resulting in pressure on the dynamics of national income. Additionally, the lower demand for exports helped to widen the current account deficit. This affected the prospects and economic growth of the country during the first half of 2015. This economic context could have an impact on the payment capacity of debtors and on the valuation of investments, affecting the soundness of the financial system. However, the results of the analysis featured in this edition of the Report show that, facing an adverse scenario, the vulnerability of the financial system in terms of solvency and liquidity is low. The analysis of the current situation of credit institutions (CI) shows that growth of the gross loan portfolio remained relatively stable, as well as the loan portfolio quality indicators, except for microcredit, which showed a decrease in these indicators. Regarding liabilities, traditional sources of funding have lost market share versus non-traditional ones (bonds, money market operations and in the interbank market), but still represent more than 70%. Moreover, the solvency indicator remained relatively stable. As for non-banking financial institutions (NBFI), the slowdown observed during the first six months of 2015 in the real annual growth of the assets total, both in the proprietary and third party position, stands out. The analysis of the main debtors of the financial system shows that indebtedness of the private corporate sector has increased in the last year, mostly driven by an increase in the debt balance with domestic and foreign financial institutions. However, the increase in this latter source of funding has been influenced by the depreciation of the Colombian peso vis-à-vis the US dollar since mid-2014. The financial indicators reflected a favorable behavior with respect to the historical average, except for the profitability indicators; although they were below the average, they have shown improvement in the last year. By economic sector, it is noted that the firms focused on farming, mining and transportation activities recorded the highest levels of risk perception by credit institutions, and the largest increases in default levels with respect to those observed in December 2014. Meanwhile, households have shown an increase in the financial burden, mainly due to growth in the consumer loan portfolio, in which the modalities of credit card, payroll deductible loan, revolving and vehicle loan are those that have reported greater increases in risk indicators. On the side of investments that could be affected by the devaluation in the portfolio of credit institutions and non-banking financial institutions (NBFI), the largest share of public debt securities, variable-yield securities and domestic private debt securities is highlighted. The value of these portfolios fell between February and August 2015, driven by the devaluation in the market of these investments throughout the year. Furthermore, the analysis of the liquidity risk indicator (LRI) shows that all intermediaries showed adequate levels and exhibit a stable behavior. Likewise, the fragility analysis of the financial system associated with the increase in the use of non-traditional funding sources does not evidence a greater exposure to liquidity risk. Stress tests assess the impact of the possible joint materialization of credit and market risks, and reveal that neither the aggregate solvency indicator, nor the liquidity risk indicator (LRI) of the system would be below the established legal limits. The entities that result more individually affected have a low share in the total assets of the credit institutions; therefore, a risk to the financial system as a whole is not observed.
