Abstract:
AbstractCredibility theory refers to the use of linear least-squares theory to approximate the Bayesian forecast of the mean of a future observation; families are known where the credibility formula is exact Bayesian. Second-moment forecasts are also of interest, for example, in assessing the precision of the mean estimate. For some of these same families, the second-moment forecast is exact in linear and quadratic functions of the sample mean. On the other hand, for the normal distribution with normal-gamma prior on the mean and variance, the exact forecast of the variance is a linear function of the sample variance and the squared deviation of the sample mean from the prior mean. Bühlmann has given a credibility approximation to the variance in terms of the sample mean and sample variance.In this paper, we present a unified approach to estimating both first and second moments of future observations using linear functions of the sample mean and two sample second moments; the resulting least-squares analysis requires the solution of a 3 × 3 linear system, using 11 prior moments from the collective and giving joint predictions of all moments of interest. Previously developed special cases follow immediately. For many analytic models of interest, 3-dimensional joint prediction is significantly better than independent forecasts using the “natural” statistics for each moment when the number of samples is small. However, the expected squared-errors of the forecasts become comparable as the sample size increases.

Abstract:
The zero-moment of an architectural undertaking precedes and the final one postpones the conventional moments of building and demolition. This pre-usage of the material and of the site turn the ‘birth’ of the house into a rather vague moment. In the numerous makings there exist prior makings, and sites often appear to be palimpsests, layer upon layer, erasure upon erasure. This manner of approaching the question of the temporal ‘sponginess’ of architecture recalls the question concerning the beginnings of architecture. In this chain of fertile ‘blackouts’, the ‘origin’ of architecture ceases to be the inaugural moment still sought to this day: in a making there exist prior makings, and in an unmaking there endures the chance of future lives, at least in principle. Moreover, the question ‘when?’ deserves another, probably more fertile for the economy of this text: ‘For how long?’

Abstract:
The purpose of this study was to compute the 3-dimensional kinetics required to swing 3 youth baseball bats of varying moments of inertia. The 306 swings by 22 male players (age 13–18 y) were analyzed. Inverse dynamics with respect to the batter’s hands were computed given the known kinematics and physical properties of the bats. Peak force increased with larger bat moments of inertia and was strongly correlated with bat tip speed. By contrast, peak moments were weakly correlated with bat moments of inertia and bat tip speed. Throughout the swing, the force applied to the bat was dominated by a component aligned with the long axis of the bat and directed away from the bat knob, whereas the moment applied to the bat was minimal until just prior to ball impact. These results indicate that players act to mostly “pull” the bat during their swing until just prior to ball impact, at which point they rapidly increase the moment on the bat. This kinetic analysis provides novel insight into the forces and moments used to swing baseball bats.

President Joe Biden recognized atrocities committed against Armenians as the Armenian Genocide in his statement on Armenian Genocide Remembrance Day (24 April 2021). The statement represents a watershed moment in US-Turkey relations. President Tayyip Erdogan can address US and international concerns prior to the Biden-Erdogan summit on the margin of June’s NATO meeting, or he can double down and intensify repression against Turkey’s ethnic and religious minorities. Erdogan’s course will define international relations prior to the centennial of the founding of the Turkish republic in 2023.

We consider minimum relative entropy calibration of a given prior distribution to a finite set of moment constraints. We show that the calibration algorithm is stable (in the Prokhorov metric) under a perturbation of the prior and the calibrated distributions converge in variation to the measure from which the moments have been taken as more constraints are added. These facts are used to explain the limiting properties of the minimum relative entropy Monte Carlo calibration algorithm.

Abstract:
In a prior study [Ye HQ, Yao DD (2016) Diffusion limit of fair resource control–Stationary and interchange of limits. Math. Oper. Res. 41(4):1161–1207.] focusing on a class of stochastic processing network with fair resource control, we justified the diffusion approximation (in the context of the interchange of limits) provided that the pth moment of the workloads are bounded. To this end, we introduced the so-called bounded workload condition, which requires the workload process be bounded by a free process plus the initial workload. This condition is for a derived process, the workload, as opposed to primitives such as arrival processes and service requirements; as such, it could be difficult to verify. In this paper, we establish the interchange of limits under a moment condition of suitable order on the primitives directly: the required order is [Formula: see text] on the moments of the primitive processes so as to bound the pth moment of the workload. This moment condition is trivial to verify, and indeed automatically holds in networks where the primitives have moments of all orders, for instance, renewal arrivals with phase-type interarrival times and independent and identically distributed phase-type service times.

Full text
Abstract:
AbstractIn Ockhamist branching-time logic [Prior 67], formulas are meant to be evaluated on a specified branch, or history, passing through the moment at hand. The linguistic counterpart of the manifoldness of future is a possibility operator which is read as ‘at some branch, or history (passing through the moment at hand)’. Both the bundled-trees semantics [Burgess 79] and the 〈moment, history〉 semantics [Thomason 84] for the possibility operator involve a quantification over sets of moments. The Ockhamist frames are (3-modal) Kripke structures in which this second-order quantification is represented by a first-order quantification. The aim of the present paper is to investigate the notions of modal definability, validity, and axiomatizability concerning 3-modal frames which can be viewed as generalizations of Ockhamist frames.

Full text
Abstract:
We define the nth moment of the transient electromagnetic impulse response as the definite integral with respect to time of the “quadrature” magnetic‐field impulse response weighted by time to the nth power. In this context, the quadrature response is defined as the full impulse response with the in‐phase component (i.e., the delta function component at zero time) removed. The low‐order moments are equivalent to familiar quantities: the zeroth moment (n = 0) is numerically equal to the frequency‐domain inductive limit, and the first moment is the resistive‐limit response. The higher order moments can be of particular benefit: successively they put greater emphasis on the late‐time data, and hence can bring out features in the data that are more conductive or deeper. An advantage of calculating moments (and hence the inductive and resistive limit) is that these data are not strongly dependent on any distortion of the waveform from an ideal impulse. Hence, it is not critical to deconvolve the data prior to estimating the moments. If a conductor has a single exponential decay, the nth moment of the decay is proportional to the nth power of the time constant of the exponential. Thus, it is relatively easy to estimate the time constant from the moments. For a conductive sphere model, the expressions for the moments are more complicated, but are still simpler than the full transient solution or the frequency‐domain solution. In a field example, the high‐order moments emphasize local highly conductive features, but also show the noise present in the late‐time data. A discrete feature on the profile evident in moments 3 through 10 has been modeled as a spherical conductor with its center at 90 m depth, a radius of 45 m, and a conductivity of 9.4 S/m.

Abstract:
Often we are confronted with heterogeneous multivariate data, i.e., data coming from several categories, and the interest may center on the differential structure of stochastic dependence among the variables between the groups. The focus in this work is on the two groups problem and is faced modeling the system through a Gaussian directed acyclic graph (DAG) couple linked in a fashion to obtain a joint estimation in order to exploit, whenever they exist, similarities between the graphs. The model can be viewed as a set of separate regressions and the proposal consists in assigning a non-local prior to the regression coefficients with the objective of enforcing stronger sparsity constraints on model selection. The model selection is based on Moment Fractional Bayes Factor, and is performed through a stochastic search algorithm over the space of DAG models.

Abstract:
This chapter explores movement and circulation across the Mediterranean and seeks to contribute to a history of proto-nationalism in the Maghrib and the Middle East at a particular moment prior to World War I. The discussion is particularly concerned with the interface of two Mediterranean spaces: the Middle East (Egypt, Ottoman Empire) and North Africa (Morocco), where the latter is viewed as a case study where resistance movements sought external allies as a way of compensating for their internal weakness. Applying methods developed by Subaltern Studies, and linking macro-historical approaches, namely of a translocal movement in the Muslim Mediterranean, it explores how the Egypt-based society, al-Ittihad al-Maghribi, through its agent, Aref Taher, used the press as an instrument for political propaganda, promoting its Pan-Islamic programme and its goal of uniting North Africa.

Chapter 2 tells the story of the crash as it unfolded. At that moment much of the public discovered a previously hidden world of obscure financial instruments and deals. Prior to the crash, the public might get only occasional glimpses of high finance when one of its components failed. In 2007, almost the entire system came crashing down. The complexity and tight coupling of the shadow banking system had created the possibility of a chain reaction and in 2007 and 2008 the chain was yanked tight. These events shocked the general public, most economists and most of the shadow bankers themselves.

Abstract:
This chapter focuses on the Harlem Globetrotters as Cold Warriors between 1947 and 1954. This is an important moment because prior to the passage of the 1954 Brown v. Board of Education decision, the State Department was in the unenviable position of trying to defend segregation while stressing racial progress. Moreover, the politics of symbolism associated with the Globetrotters' tours was designed to give legitimacy to existing racial inequalities in American society by stressing “progress” during the early Cold War era, despite the social, political, and legal barriers that hindered African American advancement. The symbol of the successful yet segregated athlete allowed the government to argue that segregation was not an impediment to the advancement of individual African Americans.

Abstract:
This book scrutinizes the events of 1919 from below: the global underside of the Wilsonian moment. During 1919 the Great Powers redrew the map of the world with the Treaties of Paris and established the League of Nations intending to prevent future war. Yet, that 1919 was a complex threshold between war and peace contested on a global scale is often missed. This process began prior to war’s end with mutinies, labour and consumer unrest, colonial revolt but reached a high point in 1919. Most obviously, the Russian Revolutions of 1917 continued into 1919 which signalled a decisive year for the Bolshevik regime. While the leaders of the Great Powers famously drew up new states in their Parisian hotel rooms, state formation also had a popular dynamic. The Irish Republic was declared. Afghanistan gained independence. Labour unrest was widespread. This year witnessed the emergence of anti-colonial insurgency and movements across Europe’s colonies; in metropolitan centres of Empire, race riots took place in the UK and during the ‘red summer’ in the US, anti-colonial movements, as well as an important moment of political enfranchisement for women but their expulsion from the wartime labour force. 1919 has many legacies: the first Arab spring, with the awakening of nationalism in the Wilsonian and Bolshevik context; the moment (after Amritsar) that Britain definitively lost its moral claim to India; the definitive announcement of Black presence in the UK; the great reversal of women’s participation in the skilled occupations; the first Fascist movement was founded.

Abstract:
This chapter moves from the more familiar white/nonwhite binary to the less commonly studied double-minority multiracial representation. The celebrity culture surrounding Tiger Woods is a vivid example of how the boundaries between black and white racial categories hinge on the exclusion or erasure of Asians from the national imagination. Until the scandal over his infidelity, sports and mainstream media celebrated Woods as the exemplar of our current colorblind moment. An analysis of his online and televised advertising campaigns and his representation in feature magazine articles prior to his adultery scandal demonstrates the difficulty of a multiracial reading in the context of colorblind rhetoric and visual practices. In contrast, postscandal publicity remakes his image from disembodied to overly embodied and debunks the argument, promoted by Woods himself, that we are beyond race and are thus blind to difference.

Abstract:
Jazz improvisation offers raw material of considerable value for issues in the philosophy of mind, but this material remains insufficiently investigated. Collective intention and distributed group attention have emerged within philosophy in recent years as fruitful areas of study: the long-entrenched dualistic picture of an inner mental event standing behind its physical manifestation has been supplanted by a model of embodied action that is unburdened by a misleading inner/outer dichotomy (so we can now see how an intentional musical work emergeswithin, and not prior to, its physical sound). This makes possible a new focus on a special form of collective intentional action that is not contained within one single mind at one given moment, but rather distributed across a group of individuals engaged in a cooperative, interactively creative performance; cases examined here include John Coltrane, among others.

Full text
Abstract:
This is the story of how Americans attempted to define what it meant to be a citizen of the United States, at a moment of fracture in the republic's history. As Erik Mathisen demonstrates, prior to the Civil War, American national citizenship amounted to little more than a vague bundle of rights. But during the conflict, citizenship was transformed. Ideas about loyalty emerged as a key to citizenship, and this change presented opportunities and profound challenges aplenty. Confederate citizens would be forced to explain away their act of treason, while African Americans would use their wartime loyalty to the Union as leverage to secure the status of citizens during Reconstruction. In The Loyal Republic, Mathisen sheds new light on the Civil War, American emancipation, and a process in which Americans came to a new relationship with the modern state. Using the Mississippi Valley as his primary focus and charting a history that traverses both sides of the battlefield, Mathisen offers a striking new history of the Civil War and its aftermath, one that ushered in nothing less than a revolution in the meaning of citizenship in the United States.

Full text
Abstract:
In Fighting for Citizenship, Brian Taylor complicates existing interpretations of why black men fought in the Civil War. Civil War–era African Americans recognized the urgency of a core political concern: how best to use the opportunity presented by this conflict over slavery to win abolition and secure enduring black rights, goals that had eluded earlier generations of black veterans. Some, like Frederick Douglass, urged immediate enlistment to support the cause of emancipation, hoping that a Northern victory would bring about the end of slavery. But others counseled patience and negotiation, drawing on a historical memory of unfulfilled promises for black military service in previous American wars and encouraging black men to leverage their position to demand abolition and equal citizenship. In doing this, they also began redefining what it meant to be a black man who fights for the United States. These debates over African Americans’ enlistment expose a formative moment in the development of American citizenship: black Northerners’ key demand was that military service earn full American citizenship, a term that had no precise definition prior to the Fourteenth Amendment. In articulating this demand, Taylor argues, black Northerners participated in the remaking of American citizenship itself—unquestionably one of the war’s most important results.

Abstract Fertility rates show dynamically–varying shapes when modeled as a function of the age at delivery. We incorporate this behavior under a novel Bayesian approach for dynamic modeling of proportionate age–specific fertility rates via skewed processes. The model assumes a skew–normal distribution for the age at the moment of childbirth, while allowing the location and the skewness parameters to evolve in time via Gaussian processes priors. Posterior inference is performed via Monte Carlo methods, leveraging results on unified skew–normal distributions. The proposed approach is illustrated on Italian age–specific fertility rates from 1991 to 2014, providing forecasts until 2030.

Our statistical mechanical informatics schemes are based on advanced mean-field methods including loopy belief propagations. This chapter explores how phase transitions appear in loopy belief propagations for prior probabilistic graphical models. The frameworks are mainly explained for loopy belief propagations in the Ising model which is one of the elementary versions of probabilistic graphical models. We also expand the schemes to quantum statistical machine learning theory. Our framework can provide us with sublinear modeling based on the momentum space renormalization group methods.

Abstract:
This chapter explores how Enlightenment arguments about the creation of imitation human beings affected thinking about literary imitation. The creation of an imitated human would at once testify to the Promethean skill of its creator and threaten the notion that human beings were more than an assemblage of mechanical parts. The chapter opens with Descartes’s efforts to distinguish between human and mechanical beings, and goes on to consider La Mettrie and early automata, including those of Jacques Vaucanson and the Jaquet-Droz family. The ‘Promethean skill’ of such imitators of human life takes on a new form in Mary Shelley’s Frankenstein, or the New Prometheus, a work which itself imitates Milton, and in which Mary Shelley herself imitates Milton’s Eve in particular. It is argued that the monster, a vast and shadowy being that is also alive, grows out of the centuries-long debate about whether an imitator generated a living imitation of an original or a mere simulacrum. That opposition is then shown to run through twentieth-century representations of cloning, including Kazuo Ishiguro’s Never Let Me Go. The ability to create digital and biological replicants, the chapter argues, has led in late modernity to an inflated valuation of supposedly ‘human’ and ‘inimitable’ qualities such as creativity. It concludes by arguing that if imitation is regarded not as direct replication or as textual copying but as a process of learning practices from prior agents it might counteract the pessimism of postmodern discussions of cloning and copying.

Abstract:
This paper concerns a description of change in the framework of tense interval logic. The main goal is to present an approach to the construction of tense paraconsistent logic. Recent investigations show that moments are inapplicable to the study of the phenomenal continuums: for many kinds of the quality changes, any subdivision of existence time of an object does not separate clearly the state before change from the state after it. It is not possible to determine the last moment of the prior state and the first moment of the posterior one. So, the predicates of natural language are not valued relatively to the moment of time. I consider change as that occupying an interval of time which has fuzzy boundaries. The description of change consists in the conjunction of the descriptions of those states which overlap an interval of change. As a result such description contains inconsistent statements.

Abstract:
The chapter serves as a historical prelude to chapters on modernism and postmodernism, by providing a historical context for how the trope of laziness evolved in American literature prior to the 20th century. First, it looks at how the motif of laziness functioned in early Puritan literature, how this function was broadened in 18th-century secular and religious didactic literature, and how it eventually developed into an aesthetic device in the Early Republic, when the new trope of laziness combined high Romantic aesthetics of the pastoral with unrefined motifs of vagabondage and delinquency, and in this way addresses the culture’s desire for freedom from the norm of collective labour and from patterns of inclusion and exclusion within the consensual networks of social participation. Second, the chapter explores the difference between the familiar Romantic topos of idleness, which has no subversive potential with respect to ethical normativity and the topos of laziness, which does. Walt Whitman’s trope of loafing is reread here via the Cynical tradition of performative indomitability as parrhēsia, or speaking truth to power. Herman Melville’s experiments with haptic poetics of laziness in Typee are interpreted as a critique of Romantic moralism and the emerging ethico-aesthetic norm of productivity.

An hour after the Marquise’s escape from Cadenet, the Chevalier de Gange and the Duc de Caderousse arrived there with the most criminal intentions. One can imagine their astonishment when they learnt of Victor’s betrayal. His wife was shown the door the moment Euphrasie’s clothes were discovered in her quarters, and strict orders were relayed to every corner of Caderousse’s estate. ‘Well, this is the greatest calamity two honourable gentlemen could suffer,’ said the Chevalier, ‘for you will acknowledge we could not possibly have been in greater agreement. I relinquished all my rights prior to the defeat of our enemy. From that moment, nothing has come between us.’

Abstract:
An alternative method for the prediction of a ship's dynamic bending stresses at sea is presented and examined in this paper. The method uses a ship's heave and pitch motion to determine the dynamic bending moment at a point along the ship's length. This can be combined with the known still water bending moment, and known ship sectional properties to determine deck and keel stresses. A combination of mathematical modeling, the random decrement, and neural network techniques have been used to determine the relationship between ship motion and bending moment, without any prior knowledge of the wave excitation level To test this method, two sets of model experiments have been used. One set from a Great Lakes bulk carrier, the other from a Canadian patrol frigate. In each experiment, the mean and variance of the bending moment have been successfully predicted, demonstrating this method as a valid approach.

Abstract:
For spine biomechanical tests, the cable-driven system in particular has been widely used to apply pure bending moments. The advantages to pure moment testing lie in its consistency as an accepted standard protocol across previous literature and its ability to ensure uniform loading across all levels of the spinal column. Of the methods used for pure moment testing, cable-driven set-ups are popular due to their low requirements and simple design. Crawford et al [1] were the first to employ this method, but prior work by our group indicated a discrepancy between applied and intended moment for this system in flexion-extension only [2]. We hypothesize that this discrepancy can be observed in other bending modes and minimized with a second-generation floating ring design to eliminate off-axis loads.

Abstract:
Since an external bending moment affects the sealing performance of pipe flange connection, it is important to investigate this effect. This paper analyzed the contact gasket stress distribution of pipe flange connections and evaluates the effect of external bending moment on the sealing performance from the viewpoint of changes in contact gasket stress. The study includes the FE analyses and the experimental leakage tests. The FE analyses suggested the large decrease of contact gasket stress at tension side and small increase at compression side. The difference in change in contact gasket stress was caused by the non-linear hysteresis characteristics of stress-displacement curve of gasket. The FE analyses also suggested that the loading order, internal pressure and external bending moment, also affected the sealing performance due to the non-linear deformation characteristic of the gasket. The sealing performance when the external bending moment applied prior to the internal pressure was degraded more than when the internal pressure was applied prior to the external bending moment. The experimental leakage tests using helium (He) gas were analyzed by the finite element method and discussed. This paper also evaluated the stress distribution in the pipe flange under external bending moment. The results suggested that the hub stress dominated the flange structure and the most important factor in designing the flange.

Abstract:
Stainless steel is increasingly popular in construction owing to its corrosion resistance, excellent mechanical and physical properties as well as its aesthetic appearance. The current paper is concerned with the use of stainless steel in steel-concrete composite beams, which is a new application. Current design codes for steel-concrete composite beams neglect strain hardening in the steel. Whilst this is a reasonable assumption for carbon steel, stainless steel is a very ductile material which offers significant levels of strain hardening prior to failure. Therefore, when current design provisions are applied to stainless steel composite beams, the strength predictions are generally inaccurate. The current study presents a simplified analytical solution that takes into consideration the strain hardening of stainless steel when bending moment capacity is calculated. A finite element model is developed and validated against a number of experimental results for composite beams. The validated numerical model is then used to investigate the accuracy of the proposed analytical solution. It is concluded that simplified analytical solution is reliable and provides a straightforward design tool for practicing engineers who wish to specify this novel construction form in appropriate applications.

Abstract:
The attitude dynamics of a spacecraft with a variable speed control moment gyroscope (VSCMG), in the presence of external torques and internal inputs, is derived using variational principles. A complete dynamics model, that relaxes some of the assumptions made in prior literature on control moment gyroscopes, is obtained. A non-standard VSCMG model, that has an offset between the center of the gimbal axis and the center of the rotor (flywheel) is considered. The dynamics equations show the complex nonlinear coupling between the internal degrees of freedom associated with the VSCMG and the spacecraft base body’s attitude degrees of freedom. Some of this coupling is induced by the non-zero offset between the gimbal axis and the rotor center. This dynamics model is then generalized to include the effects of multiple control moment gyroscopes placed in the base body with non-parallel gimbal axes. It is shown that the dynamical coupling can improve the control authority on the angular momentum of the base body of the spacecraft using changes in the momentum variables of the VSCMG. Numerical simulations confirm the use of these VSCMGs for attitude control for a given de-tumbling maneuver.

Full text
Abstract:
In previous study, the characteristics of the pipe flange connections such as the contact gasket stress distribution and the sealing performance of the connection subjected to bending moments are examined. The result suggests that the leakage increases as the bending moment increases. However, a design method for the connection subjected to bending moment is not taken into consideration. The sealing performance of the connection for the different loading history is changed due to non-linearity and hysteresis of non-asbestos gasket. After the pipe flange connections are tightened, bending moment prior to internal pressure is applied due to misalignment of the connections with bolts and nuts. So, it is necessary to examine the difference in the sealing performance due to different loading history and to establish a design method for the connections subjected to bending moment and internal pressure. In this study, the difference in the sealing performance due to different loading history is examined and pipe length in each usage condition is determined for the two loading histories using tensile strength of hub side and allowable leak rate of soppy bubble method to establish a design method of flange subjected to bending moment. The result suggests the average contact gasket stress for the different loading history is changed due to non-linearity and hysteresis of non-asbestos gasket and pipe length in each initial contact gasket stress is determined for the two loading histories.

Abstract:
Within the European Network NESC, the project NESC IV deals with constraint effects of cracks in large scale beam specimens, loaded by uni- or biaxial bending moments and containing surface or embedded cracks. The specimens are fabricated from original US RPV material, being cladded or cladding is removed. All large scale tests have been conducted at ORNL outside the NESC IV project. The outcome and the analyses of these uncladded and cladded beams containing the surface or embedded cracks are shown. By means of the finite element method, local approach methods and the Weibull stress models the specimens are analysed at the test temperatures and the probability of failure is calculated, taking into account constraint effects. For the case of the embedded cracks it turned out that the failure moment of the uncladded beam is 5% lower than the one of the cladded beam. Both crack fronts of the embedded crack are supposed to fail at the same failure moment. The results of the analysis of the cladded beam showed that the upper crack front nearer to the surface fails prior to the lower crack front, which is located deeper in the specimen (the failure moment is 5% lower). The numerical results agree very well with the experiments. The experimental failure moments could be well predicted and the failure scenario (which crack front fails first) could be determined. A theoretical shift in the transition temperature T0 due to constraint effects could be defined for both crack fronts.

Full text
Abstract:
Spacecraft attitude control using an Adaptive Singularity-free Control Moment Gyroscope (ASCMG) cluster design for internal actuation is presented. A complete dynamics model is derived using the principles of variational mechanics, relaxing some common assumptions made in prior literature on control moment gyroscopes. These assumptions include perfect axisymmetry of the rotor and gimbal structures, and perfect alignment of the centers of mass of the gimbal and the rotor. The resulting dynamics display complex nonlinear coupling between the internal degrees of freedom associated with the CMG and the spacecraft base body’s rotational degrees of freedom in the absence of these assumptions. This dynamics model is further generalized to include the effects of multiple CMGs placed in the spacecraft bus, and sufficient conditions for non-singular CMG cluster configurations are obtained. General ideas on control of the angular momentum of the spacecraft using changes in the momentum variables of a finite number of CMGs, are provided. A control scheme using a finite number of CMGs in the absence of external torques and when the total angular momentum of the spacecraft is zero, is presented. The dynamics model of the spacecraft with a finite number of CMGs is then simplified under the assumption that the rotor is axisymmetric, in which case it is shown that singularities are avoided. As an example, the case of three CMGs with axisymmetric rotors, placed in a tetrahedron configuration inside the spacecraft, is considered. The control scheme is then numerically implemented using a geometric variational integrator and the results confirm the singularity-free property and high control authority of the ASCMG cluster. Moreover, as rotor misalignments are addressed in the dynamics model, the ASCMG cluster can adapt to them without requiring hardware changes.

Abstract:
Abstract While dislocation is a leading cause of total hip replacement failure, empirical observations far outnumber systematic laboratory examinations of this phenomenon. A previously validated three-dimensional, non-linear, contact finite element model was used to study how surgical placement affects dislocation propensity. The computational model employed a widely used 22mm modular system, and examined range of motion prior to impingement as well as peak moment developed to resist dislocation under a typical leg-crossing maneuver. Results were compared to a previous study of an otherwise similar 26mm modular head system, using the same formulation. Similar trends occurred. Increasing tilt and/or anteversion increased both the range of motion and the peak resisting moment, while apparent stiffness seemed to be unaffected. Further, impingement range of motion was independent of head size, but peak resisting moment was nearly 25% less for the 22mm head sizes.

Full text
Abstract:
Studying earthquakes in Baffin Bay and the surrounding regions is challenging. There is no knowledge of earthquake activity in this region prior to 1933 when a moment magnitude (MW) 7.4 earthquake occurred in Baffin Bay. With improved instrumentation, increased seismograph coverage in the north, and modern analysis techniques, knowledge and understanding of earthquakes in the Baffin region is improving. Active seismic zones include Baffin Bay, the east coast of Baffin Island, and the Labrador Sea, separated by areas of low seismicity. Focal-mechanism solutions show a mix of faulting styles, predominantly strike-slip and thrust. Regional stress-axes orientations show more consistency, which suggests that activity is occurring on previously existing structures in response to the current stress field. There is little correlation between earthquake epicentres in Baffin Bay and mapped structures. Glacial isostatic adjustment may be a triggering mechanism for earthquakes in the Baffin region, but modelling efforts have yielded equivocal results.

Abstract:
As a result of the refugee reception crisis in 2015 the advocacy for increasing resettlement numbers in the overall refugee protection framework has gained momentum, as has research on resettlement to the EU. While the UNHCR purports resettlement as a durable solution for the international protection of refugees, resettlement programmes to the European Union are seen as a pillar of the external dimension of the EU’s asylum and migration policies and management. This paper presents and discusses the literature regarding the value transmissions taking place within these programmes. It reviews literature on the European resettlement process – ranging from the selection of refugees to be resettled, the information and training they receive prior to travelling to their new country of residence, their reception upon arrival, their placement and dispersal in the receiving state, as well as programs of private and community sponsorship. The literature shows that even if resettlement can be considered an external dimension of European migration policy, this process does not end at the border. Rather, resettlement entails particular forms of reception, placement and dispersal as well as integration practices that refugees are confronted with once they arrive in their resettlement country. These practices should thus be understood in the context of the resettlement regime as a whole. In this paper we map out where and how values (here understood as ideas about how something should be) and norms (expectations or rules that are socially enforced) are transmitted within this regime. ‘Value transmission’ is here understood in a broad sense, taking into account the values that are directly transmitted through information and education programmes, as well as those informing practices and actors’ decisions. Identifying how norms and values figure in the resettlement regime aid us in further understanding decision making processes, policy making, and the on-the-ground work of practitioners that influence refugees’ lives. An important finding in this literature review is that vulnerability is a central notion in international refugee protection, and even more so in resettlement. Ideas and practices regarding vulnerability are, throughout the resettlement regime, in continuous tension with those of security, integration, and of refugees’ own agency. The literature review and our discussion serve as a point of departure for developing further investigations into the external dimension of value transmission, which in turn can add insights into the role of norms and values in the making and un-making of (external) boundaries/borders.
