Résumé :
Under a guaranteed annuity option, an insurer guarantees to convert a policyholder's accumulated funds to a life annuity at a fixed rate when the policy matures. If the annuity rates provided under the guarantee are more beneficial to the policyholder than the prevailing rates in the market the insurer has to make up the difference. Such guarantees are common in many US tax sheltered insurance products. These guarantees were popular in UK retirement savings contracts issued in the 1970's and 1980's when long-term interest rates were high. At that time, the options were very far out of the money and insurance companies apparently assumed that interest rates would remain high and thus that the guarantees would never become active. In the 1990's, as long-term interest rates began to fall, the value of these guarantees rose. Because of the way the guarantee was written, two other factors influenced the cost of these guarantees. First, strong stock market performance meant that the amounts to which the guarantee applied increased significantly. Second, the mortality assumption implicit in the guarantee did not anticipate the improvement in mortality which actually occurred. The emerging liabilities under these guarantees threatened the solvency of some companies and led to the closure of Equitable Life (UK) to new business. In this paper we explore the pricing and risk management of these guarantees.

Résumé :
Platform marketplaces can potentially steer buyers to certain sellers by recommending or guaranteeing those sellers. Money-back guarantees—which create a direct financial stake for the platform in seller performance—might be particularly effective at steering as they align buyer and platform interests in creating a good match. We report the results of an experiment in which a platform marketplace—an online labor market—guaranteed select sellers for treated buyers. The presence of a guarantee strongly steered buyers to these guaranteed sellers, but offering guarantees did not increase sales overall, suggesting financial risk was not determinative for the marginal buyer. This preference for guaranteed sellers was not the result of their lower financial risk, but rather because buyers viewed the platform’s decision to guarantee as informative about relative seller quality. Indeed, a follow-up experiment showed that simply recommending the sellers that the platform would have guaranteed was equally effective at steering buyers. This paper was accepted by Chris Forman, information systems.

Résumé :
Purpose The purpose of this paper is to focus on public guarantees granted to micro-, small- and medium-sized enterprises (SMEs) by the Italian national credit guarantee programme (Fondo Centrale di Garanzia – Central Guarantee Fund – (CGF)). The CGF provides a direct guarantee to banks granting loans or a counter-guarantee to mutual guarantee institutions (MGIs) acting as first-level guarantors. Because the behaviour of MGIs could affect the default risk of counter-guaranteed loans, it is vital to investigate their operating and structural characteristics in order to identify an optimal design for public credit guarantee schemes (PCGSs). Design/methodology/approach Using regression models, the paper analyses the determinants of default for 33,229 SME loans guaranteed by an MGI and counter-guaranteed by the Italian CGF. The dependent variable is the ex-post default risk of SMEs’ counter-guaranteed loans in the 2010-2011 period. The explanatory variables are certain characteristics of the MGI. Findings The authors demonstrate that increases in an MGI’s leverage and the size of the counter-guaranteed portfolios increase the default risk. When the counter-guaranteed portfolio increases, MGIs are more risk taking but take less risk than when local and specialized MGIs are at play. Finally, direct public aid is relevant. Practical implications An appropriate design of the PCGS becomes crucial to controlling moral hazard in financial institutions and ensuring the financial sustainability of public intervention in favour of SMEs. Originality/value The paper evaluates an original and confidential firm-level data set that is not available in public documents or supervisory board statistics but is collected directly from the MGIs that participated in this study.

Résumé :
This study examines corporate bond guarantees by developing a theoretical model that decomposes the overall impact of a guarantee into signalling and incentive effects and presenting empirical evidence based on data from China’s corporate bond market. Our empirical research yields considerable evidence for the effects we posit in the model and provides some important insights into the problems of adverse selection and moral hazard in China’s bond market. The empirical evidence shows that the bond issuer with lower credit rating are more willing to purchase a bond guarantee and guaranteed bonds have a higher issue spread yield than those non-guaranteed bonds, even though both have the same bond credit rating. Our findings suggest that moral hazard would be better than adverse selection to explain the self- selection of bond guarantees. Prior to bond issuance credit rating signal provides a mechanism to mitigate information inequality, while bond guarantees relieve information asymmetry afterwards.

Résumé :
Purpose The purpose of this paper is to identify determinants of feasible outcome events (expired with no loss, settled for loss, still performing) and time to event of Farm Service Agency (FSA) operating and farm ownership (FO) loan guarantees. Design/methodology/approach Data on 19,126 FSA guaranteed loans, which were made by various lenders to farmers who have limited ability to obtain loans from normal sources without the Federal guarantee, were collected. Cox proportional hazards models for operating loans (OLs) and FO loans are estimated to identify borrower characteristics, loan characteristics, lender types, and farm and macroeconomic environment factors that influence guarantee outcomes. Findings Loans with different characteristics (loan amount, loan term, lender type, region originated) and assistance programs (Beginning Farmer, Interest Assistance) have differing guarantee outcomes. Contemporaneous variables, in particular delinquency status, have a significant impact on guarantee outcomes. Research limitations/implications All loans were originated in calendar years 2004 and 2005. Since FO loans may have as long as 40 year terms, results are not as robust for FO loans as for OLs. Practical implications Different loan characteristics and macroeconomic conditions significantly influence the occurrence of possible guarantee outcomes and time to the outcomes. Originality/value Guaranteed loans are the primary method of government credit assistance to US farm operators. Data on individual borrowers have been difficult to obtain for much of the life of the guaranteed program because loan applications are held privately. This study provides insight on how various factors drive guarantee performance which is useful to policy makers trying to increase guaranteed loan program efficiency.

Résumé :
In 2002, variable annuities were introduced in South Korea and have shown enormous success since then. They are life-insurance products with investment guarantees. Variable annuities allow policyholders to allocate premiums into a wide range of investment vehicles such as stocks, bonds, money market instruments, or some combinations of them. Due to the investment guarantee which is called guaranteed living benefits (GLBs), the benefit is always the greater of (1) the account value of the policyholder investment and (2) the guaranteed amount. Life insurance companies set aside reserves for the guarantees in the general account. Just as the account value depends on the performance of investments, VA lapses also rely on the performance of investments. For example, policyholders will not terminate the contracts when account value is way lower than the guaranteed amount. Considering that lapses determine the total benefit of VAs that a insurance company should pay, calculating risk margin for lapse is a key issue in the VA business. In this study, risk margin for VA lapses is estimated with Wang transform suggested by Wang (2000, 2002).

Résumé :
The mapping problem is a major player in mobile robotics, and it is essential for many real applications such as disaster response or nuclear decommissioning. Generally, the robotic mapping is addressed under the umbrella of simultaneous localization and mapping (SLAM). Several probabilistic techniques were developed in the literature to approach the SLAM problem, and despite the good performance, their convergence proof is only limited to linear Gaussian models. This thesis proposes an interval SLAM (i-SLAM) algorithm as a new approach that addresses the robotic mapping problem in the context of interval methods. The noise of the robot sensor is assumed bounded, and without any prior knowledge of its distribution, we specify soft conditions that guarantee the convergence of robotic mapping for the case of nonlinear models with non-Gaussian noise. A new theory about compact sets is developed in the context of real analysis to conclude such conditions. Then, a case study is presented where the performance of i-SLAM is compared to the probabilistic counterparts in terms of accuracy and efficiency. Moreover, this work presents an application for i-SLAM using an RGB-D sensor that operates in unknown environments. Interval methods and computer vision techniques are employed to extract planar landmarks in the environment. Then, a new hybrid data association approach is developed using a modified version of bag-of-features method to uniquely identify different landmarks across timesteps. Finally, the results obtained using the proposed data association approach are compared to the typical least-squares approaches, thus demonstrating the consistency and accuracy of the proposed approach.

Résumé :
SATISFACTION GUARANTEED AND OTHER STORIES was a collection of dark short fiction that explored the nature of hubris. Hubris was not limited to the definition of overbearing pride and arrogance, but bore a connection to love, curiosity, greed, and covetousness. In each story, the main characters' hubris sparked a desire that often lead to extreme actions. The stories' characters ranged in age from five years to centuries old. Their backgrounds were also diverse: a condemned spirit, a sculptor, a succubus posing as a psychiatrist and her empathic patient, a Rosarian, an entomologist, and a mural artist, The plots of the stories were simple and drawn from elements of myth and legend. In the essence of Edgar Allan Poe and Henry James, the stories developed the uncanny to give introspection concerning the darker human qualities.

This article describes interaction among constitutional law, international law of human rights and family law based on human rights extensive role. In family law field, involving family model and constitutional protection, it is clear to notice the influence of permanent dialogue among those three areas becoming as the main factor of family law evolution. The author emphasizes the deep transformation experienced by “family” notion through history and in fact that change shall keep happening, which does not necessarily mean that all forms of living in family shall have the same level of legal coverage. However, it should result in a minimum level of protection marked by human rights recognition.
Este artículo describe la interacción entre el derecho constitucional, el derecho internacional de los derechos humanos y el derecho de familia, cuyo fundamento es el papel extensivo de los derechos humanos. En el ámbito del derecho de familia —que implica el modelo de familia y la protección constitucional de la que goza— se ve la incidencia de este diálogo permanente entre las tres áreas, que llega a constituirse en el principal motor de la evolución del derecho de familia. El autor concluye señalando que lo que conocemos como «familia» ha experimentado una transformación profunda a través de la historia y que el cambio en su contenido seguirá variando. Esto no significa que todas las formas de vivir en familia vayan a gozar del mismo grado de cobertura legal, pero sí que debe traducirse en la existencia de un piso mínimo de protección signado por el reconocimiento de los derechos humanos.

Résumé :
Contrairement aux robots conventionnels, les robots continuums ne possèdent ni de liaisons discrètes, ni de corps rigides. Leur courbure est continue, similaire à celle des trompes ou des tentacules animales. Le développement de ce type de robots pour les applications médicales soulève plusieurs problèmes : optimisation de la conception, modélisation cinématique, choix des capteurs et commande en temps réel. Les techniques actuelles pour la modélisation des robots continuums ne tiennent pas compte les incertitudes inhérentes au système. La prise en compte de ces incertitudes est d'une importance cruciale pour la certification de tels robots utilisés pour les gestes chirurgicaux. Dans cette thèse, nous considérons un micro robot continuum à 3 actionneurs. Ce robot a été développé au laboratoire LISSI pour le traitement des anévrismes de l'aorte abdominale par chirurgie mini-invasive. Dans ce type de chirurgie, il est important de disposer d'un modèle cinématique garanti du robot continuum prenant en compte différents types d'incertitudes. Pour traiter ce problème, nous utilisons les techniques d'analyse par intervalles. Ces techniques permettent de résoudre des problèmes d'optimisation globale sous contraintes tout en prenant en compte des incertitudes aussi bien aléatoires que systématiques. La contribution de cette thèse porte sur la proposition d'un modèle cinématique d'un robot continuum prenant en compte des incertitudes liées à différents facteurs comme les erreurs d'arrondis, les erreurs paramétriques et les erreurs dues aux hypothèses de modélisation. Tout d'abord, nous développons les modèles géométriques direct et inverse du robot continuum sous forme de solutions de formes fermées. Ces solutions sont utilisées pour caractériser les différentes propriétés du robot comme la manipulabilité. Pour calculer la cinématique inverse garantie et optimale, nous appliquons une version améliorée de l'algorithme par séparation et évaluation (Branch and Bound). En considérant l'orientation du robot, la cinématique inverse est ramenée à la formulation et à la résolution par intervalles d'un problème d'optimisation sous contraintes. Les approches proposées sont validées par des simulations. Les résultats de cette thèse constituent un cadre général pour la modélisation garantie de la classe des robots continuums dont la forme est décrite par des actionneurs en flexion continue
Unlike conventional robots, continuum robots do not contain any rigid link or any rotational joint but present a continuous bending in the structure through smooth motion. Development of this class of robot for their medical application presents a common set of problems : optimization of design, kinematic modeling, sensing choice, and their control in real time. Existing techniques for the modeling of continuum robots do not take system uncertainties into account. A proper handling of these uncertainties becomes of crucial importance for the certification of such robots used as medical devices. For our research, we consider a continuum robot that has been developed for the treatment of aortic aneurysm by Minimal Invasive Surgery (MIS), in LISSI Lab. In the context of MIS, it is very important to develop a guaranteed kinematic model of robot taking into account the different types of un-certainties. To handle this problem, we use the techniques of interval analysis. These techniques are capable of performing the global optimization and solving CSPs while taking into account the different uncertainties ; no matter, whether these uncertainties are random or systematic. Contribution of this thesis is proposal of a continuum robot's kinematic model that can take system uncertainties due to different factors such as rounding errors, parametric errors, and errors due to modeling assumptions. Initially, we develop the forward and inverse kinematics of the continuum robot in closed-form formulas. These derived formulas are used for the characterization of different properties of the robot such as manipulability. To find optimized guaranteed kinematics, we retained and applied an enhanced version of branch and bound algorithm. The inverse kinematics was formulated and resolved as a constrained optimization problem for robot's orientation. The proposed approaches are validated through simulations. The results of this thesis give rise to a general framework that is valid to handle the system uncertainties for the entire class of continuum robot that are shaped by continuously bending actuators

The EM (Expectation-Maximization) algorithm is a heuristic for parameter estimation in statistical models with latent variables, where explicit computation of the maximum likelihood estimate (MLE) is infeasible. Although widely used in practice, the theoretical guarantees associated with EM are quite weak. We study the setting of a hidden Markov model (HMM) with two hidden states, where the (symmetric) transition matrix [mu] is unknown and observations are Gaussian with known covariance and unknown mean [mu]. The EM algorithm for HMMs, also known as the Baum-Welch algorithm, was previously studied by Yang, Balakrishnan, and Wainwright [1] but without global convergence guarantees. In this paper we propose a "local" version of the EM algorithm and prove absolute convergence of this algorithm to the true parameters ([mu], E) in both the population and finite-sample regime. To the best of our knowledge this is the first algorithm for simultaneous parameter estimation with global convergence guarantees. Additionally, we prove several theoretical results and supply some counterexamples for the ordinary Baum-Welch algorithm in this setting.

Résumé :
Apache Flink is a stream processing framework that provides a unified state management mechanism which, at its core, treats stream processing as a sequence of distributed transactions. Flink handles failures, re-scaling and reconfiguration seamlessly via a form of a two-phase commit protocol that periodically commits all past side effects consistently into the state backends. This involves invoking and combining checkpoints and, in time of need, redistributing the state to resume data pipelines. All the existing Flink state backend implementations, such as RocksDB, are embedded and coupled with the compute nodes. Therefore, recovery time is proportional to the state needed to be reconfigured and that can take from a few seconds to hours. If application logic is compute-heavy and Flink’s tasks are overloaded, scaling out compute pipeline means scaling out storage together with compute tasks and vice-versa because of the embedded state backends. It also introduces delays due to expensive state re-shuffle and moving large state on the wire. This thesis work proposes the decoupling of the state storage from compute to improve Flink’s scalability. It introduces the design and implementation of a new State backend, FlinkNDB, that decouples state storage from compute. Furthermore, we designed and implemented new techniques to perform snapshotting, and failure recovery to reduce the recovery time close to zero.
Apache Flink är ett strömbehandlingsramverk som tillhandahåller en enhetlig tillståndshanteringsmekanism som i sin kärna behandlar strömbehandling som en sekvens av distribuerade transaktioner. Flink hanterar fel, omskalning och omkonfigurering sömlöst via en form av ett tvåfas-engagemangsprotokoll som regelbundet begår alla tidigare biverkningar konsekvent i tillståndets backends. Detta innebär att man åberopar och kombinerar kontrollpunkter och vid behov omdistribuerar dess tillstånd för att återuppta dataledningar. Alla befintliga backendimplementeringar för Flink-tillstånd, som Rocks- DB, är inbäddade och kopplade till beräkningsnoderna. Därför är återhämtningstiden proportionell mot det tillstånd som behöver konfigureras om och det kan ta från några sekunder till timmar. Om applikationslogiken är beräkningstung och Flinks uppgifter är överbelastade, innebär utskalning av beräkningsrörledning att utskalning av lagring, tillsammans med beräkningsuppgifter och vice versa på grund av det inbäddade tillståndet i backend. Det introducerar också förseningar i förhållande till dyra tillståndsförflyttningar och flyttning av stora datamängder som upptar stora delar av bandbredden. Detta avhandlingsarbete föreslår frikoppling av tillståndslagring från beräkning för att förbättra Flinks skalbarhet. Den introducerar designen och implementeringen av ett nytt tillstånd i backend, FlinkNDB, som frikopplar tillståndslagring från beräkning. Avslutningsvis designade och implementerade vi nya tekniker för att utföra snapshotting och felåterställning för att minska återhämtningstiden till nära noll.

Résumé :
Avec le développement rapide et les applications étendues de la technologie de robot, la recherche sur le robot mobile intelligent a été programmée dans le plan de développement de haute technologie dans beaucoup de pays. La navigation autonome joue un rôle de plus en plus important dans le domaine de recherche du robot mobile intelligent. La localisation et la construction de cartes sont les principaux problèmes à résoudre par le robot pour réaliser une navigation autonome. Les techniques probabilistes (telles que le filtre étendu de Kalman et le filtre de particules) ont longtemps été utilisées pour résoudre le problème de localisation et de cartographie robotisées. Malgré leurs bonnes performances dans les applications pratiques, ils pourraient souffrir du problème d'incohérence dans les scénarios non linéaires, non gaussiens. Cette thèse se concentre sur l'étude des méthodes basées sur l'analyse par intervalles appliquées pour résoudre le problème de localisation et de cartographie robotisées. Au lieu de faire des hypothèses sur la distribution de probabilité, tous les bruits de capteurs sont supposés être bornés dans des limites connues. Sur la base d'une telle base, cette thèse formule le problème de localisation et de cartographie dans le cadre du problème de satisfaction de contraintes d'intervalle et applique des techniques d'intervalles cohérentes pour les résoudre de manière garantie. Pour traiter le problème du "lacet non corrigé" rencontré par les approches de localisation par ICP (Interval Constraint Propagation), cette thèse propose un nouvel algorithme ICP traitant de la localisation en temps réel du véhicule. L'algorithme proposé utilise un algorithme de cohérence de bas niveau et est capable de diriger la correction d'incertitude. Par la suite, la thèse présente un algorithme SLAM basé sur l'analyse d'intervalle (IA-SLAM) dédié à la caméra monoculaire. Une paramétrisation d'erreur liée et une initialisation non retardée pour un point de repère naturel sont proposées. Le problème SLAM est formé comme ICSP et résolu par des techniques de propagation par contrainte d'intervalle. Une méthode de rasage pour la contraction de l'incertitude historique et une méthode d'optimisation basée sur un graphique ICSP sont proposées pour améliorer le résultat obtenu. L'analyse théorique de la cohérence de la cartographie est également fournie pour illustrer la force de IA-SLAM. De plus, sur la base de l'algorithme IA-SLAM proposé, la thèse présente une approche cohérente et peu coûteuse pour la localisation de véhicules en extérieur. Il fonctionne dans un cadre en deux étapes (enseignement visuel et répétition) et est validé avec un véhicule de type voiture équipé de capteurs de navigation à l'estime et d'une caméra monoculaire
With the rapid development and extensive applications of robot technology, the research on intelligent mobile robot has been scheduled in high technology development plan in many countries. Autonomous navigation plays a more and more important role in the research field of intelligent mobile robot. Localization and map building are the core problems to be solved by the robot to realize autonomous navigation. Probabilistic techniques (such as Extented Kalman Filter and Particle Filter) have long been used to solve the robotic localization and mapping problem. Despite their good performance in practical applications, they could suffer the inconsistency problem in the non linear, non Gaussian scenarios. This thesis focus on study the interval analysis based methods applied to solve the robotic localization and mapping problem. Instead of making hypothesis on the probability distribution, all the sensor noises are assumed to be bounded within known limits. Based on such foundation, this thesis formulates the localization and mapping problem in the framework of Interval Constraint Satisfaction Problem and applied consistent interval techniques to solve them in a guaranteed way. To deal with the “uncorrected yaw” problem encountered by Interval Constraint Propagation (ICP) based localization approaches, this thesis proposes a new ICP algorithm dealing with the real-time vehicle localization. The proposed algorithm employs a low-level consistency algorithm and is capable of heading uncertainty correction. Afterwards, the thesis presents an interval analysis based SLAM algorithm (IA-SLAM) dedicates for monocular camera. Bound-error parameterization and undelayed initialization for nature landmark are proposed. The SLAM problem is formed as ICSP and solved via interval constraint propagation techniques. A shaving method for landmark uncertainty contraction and an ICSP graph based optimization method are put forward to improve the obtaining result. Theoretical analysis of mapping consistency is also provided to illustrated the strength of IA-SLAM. Moreover, based on the proposed IA-SLAM algorithm, the thesis presents a low cost and consistent approach for outdoor vehicle localization. It works in a two-stage framework (visual teach and repeat) and is validated with a car-like vehicle equipped with dead reckoning sensors and monocular camera

Résumé :
Architecture is inseparable from defense. From its most primitive and revered “origins,” architecture was rehearsed in environments of conflict. As an alternative to the term defense architecture, a category which typically refers to forms and types (fortresses, citadels, bastions, urban walls), this project proposes the idea of an architecture of defense. An architecture of defense sees of architecture as a reaction to some measure of paranoia and studies the built environment to recognize measures and methods used to subdue these fears. Safety Not Guaranteedexplores the architecture of paranoia through a series of design manipulations. Its setting is the network of suburbia and everyday domestic scenes—those most commonly associated with spaces of privacy, safety, and security—and where fortification occurs on the scale of the front door, the home, the cul-de-sac, the neighborhood.

Résumé :
This paper presents a methodology for analyzing the H2 guaranteed cost performance of a discrete-time LTI system with unstructured dynamic uncertainty. Using the methods of guaranteed cost control, an upper bound on H2 guaranteed cost performance over unstructured parametric uncertainty is formulated in terms of feasibility of a linear matrix inequality. It is then shown that the feasibility of this inequality also guarantees the same level of performance also over unstructured dynamic uncertainty. This is then used to formulate the problem of finding the best upper bound on H2 guaranteed cost performance over unstructured causal dynamic uncertainty as a semi-definite program. Finally, it is shown that this optimization problem can be solved efficiently and accurately using discrete algebraic Riccati equations.
