Orientalism and Oriental collections in three French national museums
Creators: name: Archer, Isabella D.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: This project focuses on Orientalist exhibitions of art and cultural artifacts from the Arabo-Islamic world in three French museums in Paris (the Louvre, the Musée du Quai Branly, and the Cité Nationale de l'Histoire de l'Immigration) in order to assess the extent to which a greater French identity is impacted by its interactions with the Other. Museums are an important part of France's history as a nation, and the history and growth of the French national museum network and its collections are a testament to the history and growth of the state. France's history and relationship with the Arabo-Islamic world, the Orient, is also a longstanding cornerstone of French identity. The prominence of Arabo-Islamic art and culture in French museums and the ways in which museums have studied and curated these works establish the important role of Orientalist exhibitions in French museums and the Orient in French history.

description: The ability to efficiently switch from one pre-encoded video stream to another (e.g., for bitrate adaptation or view switching) is important for many interactive streaming applications. Recently, stream-switching mechanisms based on distributed source coding (DSC) have been proposed. In order to reduce the overall transmission rate, these approaches provide a "merge" mechanism, where information is sent to the decoder such that the exact same frame can be reconstructed given that any one of a known set of side information (SI) frames is available at the decoder (e.g., each SI frame may correspond to a different stream from which we are switching). However, the use of bit-plane coding and channel coding in many DSC approaches leads to complex coding and decoding. In this paper, we propose an alternative approach for merging multiple SI frames, using a piecewise constant (PWC) function as the merge operator. In our approach, for each block to be reconstructed, a series of parameters of these PWC merge functions are transmitted in order to guarantee identical reconstruction given the known side information blocks. We consider two different scenarios. In the first case, a target frame is first given, and then merge parameters are chosen so that this frame can be reconstructed exactly at the decoder. In contrast, in the second scenario, the reconstructed frame and merge parameters are jointly optimized to meet a rate-distortion criteria. Experiments show that for both scenarios, our proposed merge techniques can outperform both a recent approach based on DSC and the SP-frame approach in H.264, in terms of compression efficiency and decoder complexity.
Split Sex Ratios and Genetic Relatedness in a Primitively Eusocial Sweat Bee

Subjects: subject: Life Sciences

description: How helping behaviour is maintained in eusocial species is a key topic in evolutionary biology. Colony-level sex investment ratio changes in response to relatedness asymmetries can dramatically influence inclusive fitness benefits for helpers in eusocial Hymenoptera. The extent to which helpers in primitively eusocial colonies can respond adaptively to different sources of variation in relatedness asymmetry is unclear. Using data from 109 colonies of the sweat bee Lasioglossum malachurum, we found that queen loss, but not multiple paternity or the presence of alien helpers, was correlated with colony sex investment ratios. Moreover, we quantified average helper-brood genetic relatedness to test whether it is higher than that predicted under solitary reproduction (r=0.5). Values equal to and below r=0.5 suggest that relatedness benefits alone cannot explain the maintenance of helping behaviour. Ecological benefits of group living and/or coercion must also contribute.

description: Superconducting Microstrip Single Photon Detectors (SMSPDs) are increasingly attracting the interest of the scientific community as a new platform for large area detectors with unprecedented advantaged in terms of fabrication. However, while their operativity at the telecommunication wavelength was achieved, working beyond 1.55 um is challenging. Here, we experimentally demonstrate single-photon operation of NbRe microstrips at wavelengths of 1.55 and 2 um. The devices are structured as pairs of parallel microstrips with widths ranging from 1.4 to 2.2 um and lengths from 5 to 10 um. This innovative design may assure large sensitive areas, without affecting the kinetic inductance, namely the time performance of the detectors. The results are discussed in the framework of the hot-spot two-temperature model.

description: At its simplest, pimento cheese consists of cheddar, pimiento peppers, and mayonnaise. This thesis investigates the role of pimento cheese spread in regard to a particular history, place, and context within the Piedmont of North and South Carolina to provide a name and face to the men and women who have produced and consumed the food over the past century. The history and narratives woven together about pimento cheese reveal a simple and meaningful food that provides a window into working class experience, memory, and regional identity.

We give a necessary and sufficient condition for the existence of a non-trivial $G$-equivariant fibration on $X$. We also show that two automorphisms $g_i$ of positive entropy and polarized by the same nef divisor are the same up to powers, provided that either $X$ is not an abelian surface or the $g_i$ share at least one common periodic point. The surface case is known among experts, but we treat this case together with the hyperkähler case using the same language of hyperbolic lattice and following Ratcliffe or Oguiso.

description: Introduction: As the most important centers of science production and the place of activity of students, and researchers, universities play a key role in scientific advancement and the place to give direction to intellectual, religious, and cultural movements. In Iran, with the spread of the COVID-19 epidemic and the closure of face-to-face educational centers in 2020, a deeper look at virtual education seems necessary. One of the virtual education systems is the integrated electronic unit system of the Islamic Azad University (Vadana), which was launched in order to unify and improve the quality level of offline and online education of the Islamic Azad University. Currently, the point that can be considered is students’ evaluation, its challenges and solutions in the context of virtual courses. Meanwhile, the conducted researches have presented contradictory results regarding the quality of virtual courses. In addition, due to the importance of virtual education in Iran's educational environment, no research has been done regarding the online system of Islamic Azad University, especially in relation to the field of English as a foreign language (EFL). On top of that, one of the issues that has not been addressed is the need to share knowledge in the field of EFL with regard to the performance of the online system of Islamic Azad University in the era of COVID-19.

description: We study the chiral phase transition in the presence of the chiral chemical potential $μ_5$ using the two-flavor Nambu--Jona-Lasinio model. In particular, we analyze the reason why one can obtain two opposite behaviors of the chiral critical temperature as a function of $μ_5$ in the framework of different regularization schemes. We compare the modifications of the chiral condensate and the critical temperature due to $μ_5$ in different regularization schemes, analytically and numerically. Finally, we find that, for the conventional hard-cutoff regularization scheme, the increasing dependence of the critical temperature on the chiral chemical potential is an artifact, which is caused by the fact that it does not include complete contribution from the thermal fluctuations. When the thermal contribution is fully taken into account, the chiral critical temperature should decrease with $μ_5$.

Housing First programs from a right to housing perspective

Publisher: name: University of Alberta Library
Year: 2021

The notion that Housing First (HF) is a human-rights based approach to housing some of society’s most vulnerable citizens is often alluded to in the literature, but seldom interrogated. In this paper, we examine whether HF in Alberta, Canada is practiced in a way that realizes the right to housing for chronically homeless people. We do so using four human rights principles identified by Fukuda-Parr: non-discrimination, participation, adequate progress and remedy. Based on interviews with staff of 14 HF programs in three cities, we identify constraints to a human rights-based approach, including time-limited support, which necessitates a strong emphasis on housing sustainability. We also identify positive practices, such as client participation in decision-making and tenant rights education. The paper also provides a model for systematically assessing whether HF programs respect, protect and fulfil the right to housing.

We assume that the law of the conductances is ergodic with respect to space-time shifts. We prove a quenched invariance principle for the Markov process $X$ under some moment conditions on the environment. The key result on the sublinearity of the corrector is obtained by Moser's iteration scheme.

description: Purpose – The purpose of this paper is to identify lead users within social networks of young adults between 14 and 17 years of age. Design/methodology/approach – A questionnaire and the SAGS-method were used to collect data within seven high schools in the north of The Netherlands. These data were used to empirically test five hypotheses using the variables which could enable the identification of lead users. A multiple regression analysis was used to test the predictive value of the variables. The analysis was complemented with a qualitative analysis of the collected data. Findings – The main characteristics which identify lead users among adults can also be used with young adults. Those young adults who are more likely to be a lead user, are more ahead of a trend and have a higher amount of expected benefit. They also display more expertise than other young adults. Research limitations/implications – The variable of perceived information benefits could complement the variables used for identifying lead users among young adults, but further research is necessary. Because the focus is on only one specific product, the generalizability of the results from this research is limited. Further research should include different products or services in different domains of interest. The variables of perceived information benefits and efficiency did not have a significant positive relation with lead userness, but further research is needed. Practical implications – The identification of lead users could be valuable to organizations that focus on young adults in the age range 14 to 17 years and could lead to significant commercial benefits. Young adults are a large potential market and the identification of lead users within this target group could help organizations Originality/value – Research on lead user theory ismainly focused on adults or organizations. This article tries to fill this research gap by focusing on young adults. It is an extension of the research of Kratzer and Lettl, Kunst and Kratzer and Molenmaker et al. who focused on children from 8 to 12 years old.

description: The ground-state phase diagram and quantum phase transitions (QPTs) in a spin-1 compass chain are investigated by the infinite time-evolving block decimation (iTEBD) method. Various phases are discerned by energy densities, spin correlations and entanglement entropy. A generalized string correlator is found to be capable of describing the nonlocal string order in the disordered phase. Furthermore, in the noncritical disordered phase, the spin-spin correlations are found to decay exponentially. Except for a multicritical point ($J_{1}=0$, $J_{2}=0$), the QPTs are determined to have second-order characters. In addition, the central charges on these critical phase boundaries are determined to be $c$=1/2, therefore these QPTs belong to the Ising universality class.

description: A hypergraph is said to be properly 2-colorable if there exists a 2-coloring of its vertices such that no hyperedge is monochromatic. On the other hand, a hypergraph is called non-2-colorable if there exists at least one monochromatic hyperedge in each of the possible 2-colorings of its vertex set. Let m(n) denote the minimum number of hyperedges in a non-2-colorable n-uniform hypergraph. Establishing the lower and upper bounds on m(n) is a well-studied research direction over several decades. In this paper, we present new constructions for non-2-colorable n-uniform hypergraphs. These constructions improve the upper bounds for m(8), m(13), m(14), m(16) and m(17). We also improve the lower bound for m(5).
Dynamics of drug trafficking: Results from a simple compartmental model

description: In this work we propose a simple model for the emergence of drug dealers. For this purpose, we built a compartmental model considering four subpopulations, namely susceptibles, passive supporters, drug dealers and arrested drug dealers. The target is to study the influence of the passive supporters on the long-time prevalence of drug dealers. Passive supporters are people who are passively consenting to the drug trafficking cause. First we consider the model on a fully-connected newtork, in such a way that we can write a rate equation for each subpopulation. Our analytical and numerical results show that the emergence of drug dealers is a consequence of the rapid increase number of passive supporters. Such increase is associated with a nonequilibrium active-absorbing phase transition. After that, we consider the model on a two-dimensional square lattice, in order to compare the results in the presence of a simple social network with the previous results. The Monte Carlo simulation results suggest a similar behavior in comparison with the fully-connected network case, but the location of the critical point of the transition is distinct, due to the neighbors' correlations introduced by the presence of the lattice.

A regularised singularity approach to phoretic problems

description: An efficient, accurate, and flexible numerical method is proposed for the solution of the swimming problem of one or more autophoretic particles in the purely-diffusive limit. The method relies on successive boundary element solutions of the Laplacian and the Stokes flow equations using regularised Green's functions for swift, simple implementations, an extension of the well-known method of "regularised stokeslets" for Stokes flow problems. The boundary element method is particularly suitable for phoretic problems, since no quantities in the domain bulk are required to compute the swimming velocity. For time-dependent problems, the method requires no re-meshing and simple boundaries such as a plane wall may be added at no increase to the size of the linear system through the method of images. The method is validated against two classical examples for which an analytical or semi-analytical solution is known, a two-sphere system and a Janus particle, and provides a rigorous computational pipeline to address further problems with complex geometry and multiple bodies.

Untersucht wurden die Wirkungen von Judo auf Aspekte der motorischen Leistungsfähigkeit, des prosozialen Verhaltens und der Ich-Stärke von Kindern. Hierfür kamen sowohl quantitative als auch qualitative Methoden zum Einsatz. Die hier vorgestellten Ergebnisse der quantitativen Teilstudie weisen darauf hin, dass Judo im Schulsport die Kraftausdauerfähigkeit verbessern kann und das Potential besitzt, die sportbezogene Selbstwirksamkeit positiv zu beeinflussen. Die Wirkungen auf prosoziales Verhalten können allein durch die quantitativen Daten nicht abschließend beurteilt werden.

Tunneling diodes under environmental effects

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We examine the robustness of single-molecule tunneling diodes to thermal-environmental effects. The diode comprises three fragments: two different conjugated chemical groups at the boundaries, and a saturated moiety in between, breaking conjugation. In this setup, molecular electronic levels localized on the conjugated groups independently shift with applied bias. While in the forward polarity a resonance condition is met, enhancing conductance, in the reversed direction molecular electronic states shift away from each other, resulting in small tunneling currents. In the absence of interactions with a thermal environment (consisting e.g. internal vibrations, solvent), rectification ratios reach three orders of magnitude. We introduce decoherence and inelastic-dissipative effects phenomenologically, by using the "voltage probe" approach. We find that when $γ_d \lesssim v$, with $γ_d$ the interaction energy of electrons with the environment and $v$ the tunneling energy across the saturated link, the diode is still highly effective, though rectification ratios are cut down by a factor of 2-4 compared to the coherent limit. To further enhance rectification ratios in molecular diodes we suggest a refined design involving four orbitals, with a pair of closely spaced states at each conjugated moiety.

description: We introduce a theory of volume polynomials and corresponding duality algebras of multi-fans. Any complete simplicial multi-fan $Δ$ determines a volume polynomial $V_Δ$ whose values are the volumes of multi-polytopes based on $Δ$. This homogeneous polynomial is further used to construct a Poincare duality algebra $\mathcal{A}^*(Δ)$. We study the structure and properties of $V_Δ$ and $\mathcal{A}^*(Δ)$ and give applications and connections to other subjects, such as Macaulay duality, Novik--Swartz theory of face rings of simplicial manifolds, generalizations of Minkowski's theorem on convex polytopes, cohomology of torus manifolds, computations of volumes, and linear relations on the powers of linear forms. In particular, we prove that the analogue of the $g$-theorem does not hold for multi-polytopes.

PHONETIC MOTIVATION FOR DIACHRONIC SOUND CHANGE IN BANTU LANGUAGES AS EVIDENCED BY VOICELESS PRENASALIZED STOP PERCEPTION BY NATIVE SOMALI CHIZIGULA SPEAKERS
Creators: name: Boone, Haley
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Two hypotheses were tested as triggering nasal effacement (leaving an aspiration contrast) in voiceless prenasalized stops in Bantu languages:
      Aspiration is more reliably produced than voiceless nasalization.
      Voiceless nasalization is harder to hear than aspiration.
      Productions from two Somali Chizigula speakers were measured to test the cue reliability of nasalization amplitude versus aspiration duration. Aspiration is a more reliably produced cue, providing better distinction between voiceless stops.
      The perception of voiceless nasalization and aspiration by 10 Somali Chizigula participants was tested. Native productions of voiceless prenasalized and plain stops were cross-spliced to contain pre-burst information from one stop type and post-burst from the other. Participants then identified each stimulus as prenasalized or plain.
      Nasalized-only stimuli were identified as “prenasalized” significantly less than control prenasalized stimuli, but aspirated-only stimuli did not receive significantly less “prenasalized” responses than prenasalized controls.
      Aspiration appears easier to hear, but not more heavily weighted than nasalization.

description: Spectacular Body Images: Fantasies of Reproduction and Sexual Representation in Inez van Lamsweerde’s Artworks An image of the (human) body is always necessary for fantasies of reproduction to be developed – in science as well as art. Inze van Lamsweerde’s series “Thank you Thighmaster” (1993) works with computer-manipulated photographs and provides an opportunity to discuss the question whether these fantasies of reproduction have to be regarded as completely artificial. The non-sexed body images refer to a dilemma within the discourse on reproduction: On the one hand, these bodies appear desirable because of the model’s beauty. On the other, however, the cyborgs cannot respond to the desire since they lack any reproductive ability. Thus they emphasize a gap within the technical evolution: You may overcome space and time but you always need a body to do so.

Supernatural persuasion and Luis de Molina's theology in three of Tirso de Molina's works: El burlador de Sevilla (1630), El condenado por desconfiado (1635) and Quien no cae no se levanta (1636)

description: This article seeks to reveal Tirso de Molina's view of auxiliis through analysis of three of his religious plays, El burlador de Sevilla (1630), El condenado por desconfiado (1635) and Quien no cae no se levanta (1636). While several aspects of Tirso's theological perspective have been well researched, the supernatural characters and their theological implications have received practically no scholarly attention. This study demonstrates that the playwright utilizes these characters to illustrate his personal belief in man's free will. In order to explore his theological perspective, the essay first briefly looks at the presiding debate of auxiliis in its historical context and then analyzes the dramatic functions of three distinct manifestations of supernatural forces in the plays: the demonic manipulation in El condenado por desconfiado, the ghostly apparition of Don Gonzalo in El burlador de Sevilla and divine messengers' attempt to win souls in both the plays aforementioned and Quien no cae no se levanta.

We identified 'by eye' a transiting system, UScoJ161630.68-251220.1 (=EPIC203710387) with a combined spectral type of M5.25 whose photometric, astrometric, and spectroscopic properties makes it a member of USco. We conducted an extensive photometric and spectroscopic follow-up of this transiting system with a suite of telescopes and instruments to characterise the properties of each component of the system. We calculated a transit duration of about 2.42 hours occuring every 2.88 days with a slight difference in transit depth and phase between the two components. We estimated a mass ratio of 0.922+/-0.015 from the semi-amplitudes of the radial velocity curves for each component. We derived masses of 0.091+/-0.005 Msun and 0.084+/-0.004 Msun,radii of 0.388+/-0.008 Rsun and 0.380+/-0.008 Rsun, luminosities of log(L/Lsun)=-2.020 (-0.121+0.099) dex and -2.032 (-0.121+0.099) dex, and effective temperatures of 2901 (-172+199) K and 2908 (-172+199) K for the primary and secondary, respectively. We present a complete photometric and radial velocity characterisation of the least massive double-line eclipsing binary system in the young USco association with two components close to the stellar/substellar limit. This system fills in a gap between the least massive eclipsing binaries in the low-mass and substellar regimes at young ages and represents an important addition to constrain evolutionary models at young ages.

description: We analyze the migration characteristics of a droplet in an oscillatory flow field in a parallel plate micro-confinement. Using phase filed formalism, we capture the dynamical evolution of the droplet over a wide range of the frequency of the imposed oscillation in the flow field, drop size relative to the channel gap, and the capillary number. The latter two factors imply the contribution of droplet deformability, commonly considered in the study of droplet migration under steady shear flow conditions. We show that the imposed oscillation brings in additional time complexity in the droplet movement, realized through temporally varying drop-shape, flow direction and the inertial response of the droplet. As a consequence, we observe a spatially complicated pathway of the droplet along the transverse direction, in sharp contrast to the smooth migration under a similar yet steady shear flow condition. Intuitively, the longitudinal component of the droplet movement is in tandem with the flow continuity and evolves with time at the same frequency as that of the imposed oscillation, although, with an amplitude decreasing with the frequency. The time complexity of the transverse component of the movement pattern, however, cannot by rationalized through such intuitive arguments. Towards bringing out the underlying physics, we further endeavor in a reciprocal identity based analysis. Following this approach, we unveil the time complexities of the droplet movement, which appear to be sufficient to rationalize the complex movement patterns observed through the comprehensive simulation studies. These results can be of profound importance in designing droplet based microfluidic systems in an oscillatory flow environment.

description: Visualizations? On Harmonic Structures as Universal Patterns This article analyzes the role of “harmonics” in western art historical discourse. Hövelmeyer takes the work of the psychiatrist Leo Bader as an example of the role of images, the discourse on the artist, and the interrelationship of artistic and scientific authority. We see how the historical and contemporary position of the male scientist is embedded in aesthetic premises, to which little reflection has been given.

description: Using high resolution Cluster satellite observations, we show that the turbulent solar wind is populated by magnetic discontinuities at different scales, going from proton down to electron scales. The structure of these layers resembles the Harris equilibrium profile in plasmas. Using a multi-dimensional intermittency technique, we show that these structures are connected through the scales. Supported by numerical simulations of magnetic reconnection, we show that observations are consistent with a scenario where many current layers develop in turbulence, and where the outflow of these reconnection events are characterized by complex sub-proton networks of secondary islands, in a self-similar way. The present work establishes that the picture of "reconnection in turbulence" and "turbulent reconnection", separately invoked as ubiquitous, coexist in space plasmas.
Zu ähnlich – Neue Klitorisbilder aus Kunst und Wissenschaft

description: Too Similar: New Images of the Clitoris in Art and Science What influence do visual and especially digital media have on what is conceived of as a body, especially a female body, from a medical point of view? With examples of new 3D visualizations in film, television, and the fine arts based on a short paper in the US Journal of Urology in 1998 by Helen O’Connell, a “new” discourse on the clitoris is analyzed. Two narratives are found to interweave in this process: one, the belief in 3D visualization derived with the “truth machine” computer; and the other, a claim to the first “objective” anatomical description of the female body by a woman researcher. Instead of referencing feminist and historical anatomical findings, a notion of ahistorical “objectivity” is maintained that interlocks perfectly with the popular myths of the visually unveiled “truth” of the body by digital media. A blow to psychoanalysis, especially Sigmund Freud, is added to these evidence myths with an acclaimed “end of penis envy” through the revelation of the true size of the clitoris. Ironically it was Freud who based his writings on the “real little penis of the woman” – anatomically well informed by the excellent nineteenth-century German anatomical literature on the clitoris.

The Electromagnetic Green's Function for Layered Topological Insulators

description: The dyadic Green's function of the inhomogeneous vector Helmholtz equation describes the field pattern of a single frequency point source. It appears in the mathematical description of many areas of electromagnetism and optics including both classical and quantum, linear and nonlinear optics, dispersion forces (such as the Casimir and Casimir-Polder forces) and in the dynamics of trapped atoms and molecules. Here, we compute the Green's function for a layered topological insulator. Via the magnetoelectric effect, topological insulators are able to mix the electric, E, and magnetic induction, B, fields and, hence, one finds that the TE and TM polarizations mix on reflection from/transmission through an interface. This leads to novel field patterns close to the surface of a topological insulator.

description: Big data is one of the most discussed, and possibly least understood, terms in use in business today. Big data is said to offer not only unprecedented levels of business intelligence concerning the habits of consumers and rivals, but also to herald a revolution in the way in which business are organized and run. However, big data is not as straightforward as it might seem, particularly when it comes to the so-called dark data from social media. It is not simply the quantity of data that has changed, it is also the speed and the variety of formats with which it is delivered. This article sets out to look at big data and debunk some of the myths that surround it. It focuses on the role of data from social media in particular and highlights two common myths about big data. The first is that because a data set contains billions of items, traditional methodological issues no longer matter. The second is the belief that big data is both a complete and unbiased source of data upon which to base decisions.
"One face with tow sexes"? - Versuch, die Erkenntnisse aus einem psychophysikalischen Experiment zu deuten

description: One Face with Two Sexes?: Attempting to Analyze the Insights of a Psychophysical Experiment This article analyzes some very specific processes of knowledge and evidence production in the field of human psychophysics concerning the question of whether gender is a category of human visual perception, specifically of face recognition. Methodologically speaking, the article conducts a discursive analysis on a micro-political level and addresses the question of how the experiment itself and the form of knowledge behind it, together with the media devices employed, produce some kind of truth or evidence about gender as it is represented in the form of text, diagrams, and pictures. This kind of scientific “truth” was published in, Vision, one of the field’s preeminent scientific journals, in 2005. The media technique used in the experiment is a morphing procedure based on complicated statistical-mathematical calculations and elaborated algorithms. In terms of effect on the level of image production, the medium primarily erased all differences between two categories of sex, which were extracted from “reality” and then digitalized, but also an a priori presumption on the part of the experimenters. The following article shows how the morphing procedure destabilizes this presumption on an epistemological level; how the process of presenting the images to the subjects in a static, photographic manner seeks to regulate this destabilization; and how, finally, the presumption is – as experimental solution – at the risk of being unverifiable, but for this very reason has to be rationalized and reestablished in order to keep sexual difference intelligible in the form of two categories of sex.

Equivalence of two Fixed-Point Semantics for Definitional Higher-Order Logic Programs

description: Two distinct research approaches have been proposed for assigning a purely extensional semantics to higher-order logic programming. The former approach uses classical domain theoretic tools while the latter builds on a fixed-point construction defined on a syntactic instantiation of the source program. The relationships between these two approaches had not been investigated until now. In this paper we demonstrate that for a very broad class of programs, namely the class of definitional programs introduced by W. W. Wadge, the two approaches coincide (with respect to ground atoms that involve symbols of the program). On the other hand, we argue that if existential higher-order variables are allowed to appear in the bodies of program rules, the two approaches are in general different. The results of the paper contribute to a better understanding of the semantics of higher-order logic programming.

Software tools and guide for viscoelastic creep experiments

Publisher: name: University of North Carolina at Chapel Hill

description: Models predicting strain as a function of time are fit to data obtained from creep recovery experiments on viscoelastic materials. Here we discuss standard non-inertial and instrument-induced inertial creep experiments. We first summarize and illustrate key signatures, which differentiate the models and highlight properties of creep data. The basic signatures distinguishing a solid versus fluid response, respectively, are: a sudden versus gradual rise when a stress impulse is applied; a sudden versus gradual decline when a constant stress is suddenly removed; and recovery to zero strain versus a finite steady state after the applied stress is removed. For completeness, we discuss development of the models, solution methods, and parameter influence on behavior. Finally, software created by Dr. Ke Xu to estimate the model parameters that best fit the experimental data is adapted to illustrate the influence of experimental noise in parameter recovery.
