Abstract

Performing orbital insertion around Mars using aerocapture instead of a propulsive orbit insertion manoeuvre allows to save resources and/or increase the payload mass fraction. Aerocapture has never been employed to date because of the high uncertainties in the parameters from which it depends, mainly related to atmospheric density modeling and navigation errors. The purpose of this work is to investigate the feasibility of aerocapture at Mars with an innovative deployable drag device, whose aperture can be modulated in flight, and assess the effects of the main uncertainties on the success of the manoeuvre. This paper starts with the presentation of a parametric bi-dimensional analysis of the effectiveness of aerocapture, for which a wide range of uncertainty levels in the atmospheric density and the ballistic coefficient are considered. Then, an application to a real mission scenario is carried out including the error of the targeting manoeuvre performed at the limit of the sphere of influence of the planet. The analyses show the strong influence of the uncertainties in the atmospheric density and the ballistic coefficient, which significantly narrow the solution space and limit its continuity. However, viable solutions for aerocapture can still be identified even in the worst conditions.

Abstract

BACKGROUND Indicators of relative inequality of lifespans are important because they capture the dimensionless shape of aging. They are markers of inequality at the population level and express the uncertainty at the time of death at the individual level. In particular, Keyfitz' entropy $\bar{H}$ represents the elasticity of life expectancy to a change in mortality and it has been used as an indicator of lifespan variation. However, it is unknown how this measure changes over time and whether a threshold age exists, as it does for other lifespan variation indicators. RESULTS The time derivative of $\bar{H}$ can be decomposed into changes in life disparity $e^\dagger$ and life expectancy at birth $e_o$. Likewise, changes over time in $\bar{H}$ are a weighted average of age-specific rates of mortality improvements. These weights reflect the sensitivity of $\bar{H}$ and show how mortality improvements can increase (or decrease) the relative inequality of lifespans. Further, we prove that $\bar{H}$, as well as $e^\dagger$, in the case that mortality is reduced in every age, has a threshold age below which saving lives reduces entropy, whereas improvements above that age increase entropy. CONTRIBUTION We give a formal expression for changes over time of $\bar{H}$ and provide a formal proof of the threshold age that separates reductions and increases in lifespan inequality from age-specific mortality improvements.

Abstract

This investigation explores the interactions of different shaped debris with an array of obstacles under subcritical flow conditions, representative of a flood associated with a storm surge or tsunami. Panels, blocks and cylinders were used in a flow channel, as analogues for house panels, cars/containers and trees respectively, whilst some tests used a mix of debris. The backwater effect due to the blockage caused by the obstacles was most (least) significant for panels (cylinders). There was some evidence that smaller key log types and higher flow rates led to smaller dams. It was also evident that key logs formed at different depths depending on debris shape; debris shape also determined the vertical shape of the dam. Capture efficiency had a broadly negative (positive) correlation with the Froude number (permeability). Also, from video footage there were examples of the debris moving more quickly through partial dams. Finally, the drag force, deduced from only the water depths and the flow discharge, showed a clear relationship between drag force and Froude number, and a dependency of drag force on debris shape. There are some implications for the layout of building footprints in the inundation zones and the use of large, break‐away panels. [ABSTRACT FROM AUTHOR]

27. Rewriting formalisms with binding support : comparing combinatory reduction systems and nominal rewrite systems with atom substitution

Abstract

In this thesis, two extensions of term rewriting systems with binding support are compared: Nominal Rewrite Systems defined by Fernández, Gabbay and Mackie (Fernández and Gabbay, 2007; Fernández et al., 2004) and Combinatory Reduction Systems, a well-established higher-order rewriting formalism introduced by Klop (Klop, 1980; Klop et al., 1993). Higher-order term rewriting is a collective name for a large number of different formalisms combining term rewriting systems and the λ-calculus, a formal system for expressing functional computation which provides to term rewriting systems a notion of binding and substitution as primitive. Nominal rewriting allows a first-order approach to binding where variables, both free and abstracted, can be directly manipulated and α-equality is formally axiomatised in the logic by means of a swapping operation and a freshness relation. Despite the differences in their underlying semantic foundations, nominal and higher-order rewriting formalisms are closely related to each other. The relationship between Combinatory Reduction Systems and other higher-order rewriting formalisms has already been well documented (see for instance (Bertolissi et al., 2006; Kop, 2012; van Oostrom and van Raamsdonk, 1994; van Raamsdonk, 1999)). In (Fernández et al., 2004), Fernández, Gabbay and Mackie presented an encoding of Combinatory Reduction Systems into Nominal Rewrite Systems showing the rewrite relation to be preserved when adding to the encoded system a set of rules simulating higher-order substitution from the λ-calculus. This immediately poses two areas of study that are addressed in this thesis, the simulation of nominal rewriting in Combinatory Reduction Systems and an extension of Nominal Rewrite Systems where higher-order substitution for nominal terms is provided as primitive. As a result, the naturality of the encoded Combinatory Reduction System in nominal rewriting is improved in the sense that the rewrite relation is not only preserved but also reflected. This thesis aims to unify both rewriting communities by providing a concrete correspondence between Combinatory Reduction Systems and the nominal rewriting framework. There is a theoretical interest in showing such correspondence because the expressive power of nominal and higher-order rewriting is put in evidence. Techniques to prove confluence and termination of higher-order rewriting systems were studied in (Hamana, 2010; Klop et al., 1993; Mayr and Nipkow, 1998) amongst others. However, the syntax and type restrictions imposed on rewrite rules in these systems have prevented the design of completion procedures for higher-order rewrite systems (Nipkow and Prehofer, 1998). Nominal terms enjoy many useful properties, for instance, unification modulo α-equivalence is decidable and unitary (Urban et al., 2004) and nominal matching is linear (Calvès and Fernández, 2008a). Nominal rewriting can be implemented efficiently if we use closed rules, roughly speaking, closed rules do not contain unabstracted atoms and preserve the binding status of atoms during reduction - a natural restriction which is also imposed on Combinatory Reduction Systems by definition as well as other wellknown higher-order formalisms (e.g. HRSs (Nipkow, 1991) and ERSs (Glauert et al., 2005; Khasidashvili, 1990)). Additionally, a completion algorithm for Nominal Rewrite Systems has been designed by Fernández and Rubio in (Fernández and Rubio, 2012). Therefore a practical interest arises, that of the possibility of transferring results between nominal rewriting and higher-order term rewriting by reason of the existing translations between Combinatory Reduction Systems and other higher-order rewriting formalisms. In particular, techniques and properties of the rewriting relation such as termination can be exported from nominal rewriting to Combinatory Reduction Systems. This thesis first defines a pair of translation functions from Combinatory Reduction Systems to Nominal Rewrite systems and vice versa where the rewrite relation is preserved and (almost) reflected. The translation from Combinatory Reduction Systems to Nominal Rewrite systems is based on the translation given in (Fernández et al., 2004) where some issues have been corrected from the original translation as well as improving the naturality of the encoding by using closed rewriting, a formal treatment of the Barendregt variable convention in rule induction. An extension of nominal terms is then studied, where captureavoiding substitution of atoms by terms is implemented in the syntax. Properties of the extended theory and an algorithmic representation of α-equality are then derived, providing a framework in which the notion of unification of extended nominal terms is defined, along with a proof of undecidability constructed by implementing an effective method to reduce Hilbert’s tenth problem to unification of nominal terms extended with atom substitution. Two matching algorithms are then specified, a general one that finds the set of all possible correct solutions and only correct solutions to any (unifiable) matching problem by imposing a syntactic restriction on the matching algorithm to avoid instantiation of variables on one side of the matching constraint, and a unitary simple-matching algorithm which enjoys the property of unique most general solutions for the class of simple matching constraints. Both matching algorithms are then applied to the extension of Nominal Rewrite Systems we describe, providing an operational definition of closedness for extended nominal terms and, in the case of the simple-matching algorithm, finding a match during the rewriting process. Finally, we use the framework of extended nominal rewriting to provide a one-step reduction preserving translation from Combinatory Reduction Systems to standard extended Nominal Rewrite Systems as well as a reduction-preserving translation from the class of standard extended Nominal Rewrite Systems to Nominal Rewrite Systems.

The diverse morphological configurations in teeth present clinical challenges in root canal treatment, complicating instrumentation and irrigation processes, which can lead to treatment failure. Understanding anatomical variations, such as C-shaped canals and radix entomolaris, enhances clinical skills and improves long-term endodontic treatment success rates. Cone-beam computed tomography (CBCT) offers superior diagnostic capabilities over conventional radiography, enabling the pre-operative detection of root configurations and canal numbers, facilitating personalized endodontic treatments. A total of 2173 teeth of a Mexican population, including 1057 first mandibular molars and 1116 s mandibular molars, were studied using only CBCT to identify C-shaped canals and radix configurations of patients who were treated from 2018 to 2023 at the Department of Radiology at the Faculty of Dentistry, Juarez University of the State of Durango, Mexico. C-shaped canals were identified in 160 teeth, with a prevalence of 0.2% in first mandibular molars and 14.1% in second mandibular molars. The highest frequency was in the left second mandibular molar (3.7) at 14.8%. Gender differences were significant, with higher prevalence in females (27.3%) compared to males (13.3%). The most common C-shaped canal configuration was type C2 (39.3%). Radix entomolaris was found in 52 teeth, with a prevalence of 3.4% in first mandibular molars and 1.4% in second mandibular molars. This research on a Mexican population using cone-beam computed tomography (CBCT) highlights significant findings in the prevalence and types of C-shaped canals and radix entomolaris in mandibular molars for this population. The left second mandibular molar (3.7) showed the highest prevalence at 14.8%, followed closely by the right second mandibular molar (4.7) at 13.5%, with a significant difference (p < 0.001). We found a significant difference in the prevalence of C-shaped canals between genders (p = 0.004, OR 1.78). Additionally, radix entomolaris (p < 0.001) was more frequently identified in first mandibular molars to a significant degree. These insights underscore the importance of CBCT in diagnosing complex root anatomies, which can greatly enhance the success rates of endodontic procedures by allowing for more tailored and precise treatments for this population.
