description: Sulphate attack of concretes and mortars is a very complex process which is not yet fully understood. It was the purpose of this thesis to evaluate the influence of two western North American fly ashes on sulphate durability. In this work care was taken to eliminate sources of experimental variability by controlling the quality of (a) the attacking environment and (b) the material composition. The attacking environments were (a) combined sulphate solution (0.176 Mol Na2so4 + 0.176 Mol Mgso4·7H20) and (b) water. Both were kept at pH 7, pH 9.5 and pH uncontrolled. Sulphuric acid (H2so4) was added once daily to keep pH constant. Mortar bars were exposed to experimental conditions when they reached (a) constant strength (21 Â± MPa) or (b) constant calcium hydroxide content (15% plain mortars,10.5Â± 0.5% blended mortars). Ordinary Portland cement (Type 10) and sulphate resistant cement (Type 50) were employed. Sundance and Laramie fly ashes (sub-bituminous ashes) were used in two levels of replacement, 35 and 50% by volume. Water/cement ratio by mass of 0.47 was used. The extent of attack was evaluated by linear expansion measurement. At the end of the testing period (6, 9 or 12 months) compressive and tensile strength measurements were performed and micros true ture of mortars was examined by means of x- ray diffraction and thermogravimetric analyses. Laramie fly ash reduced sulphate resistance at both levels of ash replacement. Sundance fly ash improved sulphate durability of ordinary Portland cement as measured by linear expansion. Increased rate of expansion was displayed by bars exposed to sulphate solution at pH 7 after 250 days of immersion. Generally, though, consistent dependency of extent of attack on the pH of the solution was not detected.

Abstract

Before software can be formally reasoned about, it must first be represented in some form of logic. There are two approaches to carrying out this translation: the first is to generate an idealised representation of the program, convenient for reasoning about. The second, safer approach is to perform a precise, conservative translation, at the cost of burdening verification efforts with low-level implementation details. In this thesis, we present methods for bridging the gap between these two approaches. In particular, we describe algorithms for automatically abstracting low-level C code semantics into a higher level representation. These translations include simplifying program control flow, converting finite machine arithmetic into idealised integers, and translating the byte-level C memory model to a split heap model. The generated abstractions are easier to reason about than the input representations, which in turn increases the productivity of formal verification techniques. Critically, we guarantee soundness by automatically generating proofs that our abstractions are correct. Previous work carrying out such transformations has either done so using unverified translations, or required significant manual proof engineering effort. Our algorithms are implemented in a new tool named AutoCorres, built on the Isabelle/​HOL interactive theorem prover. We demonstrate the effectiveness of our abstractions in a number of case studies, and show the scalability of AutoCorres by translating real-world programs consisting of tens of thousands of lines of code. While our work focuses on a subset of the C programming language, we believe most of our algorithms are also applicable to other imperative languages, such as Java or C#.

description: Authoring languages for Computer Assisted Learning (CAL) have undergone significant developments during the last 25 years. The languages used in the early mainframe computer and minicomputer CAL projects were initially limited by available hardware facilities. Nevertheless, attempts were made to provide authoring flexibility and to implement desirable instructional paradigms. Many CAL programs for the early microcomputers were written in general purpose programming languages. However, the difficulty of using these and their limitations led to the development of CAL application languages, some converted from mainframe counterparts and others produced especially for microcomputer courseware authoring. With limitations of processing speed, memory, and inflexible authoring features, these application languages were frequently perceived by authors as being too restricted. As microcomputers have become more powerful and as they have acquired extensive memory on hard disk, they have also become capable of supporting languages more suitable for CAL authoring. In effect, these languages may be classified into three types: more powerful general purpose programming languages, object oriented languages, and graphics oriented languages. In order to assess the value of such languages in a variety of teaching/ learning applications, three CAL programs were written. The first, written in a general purpose language extended by means of templates, macros, and a shell, was concerned with English grammar. The second, written in a powerful object oriented language, was intended to teach the process of creating an outline. The third, written in a graphics oriented language with built­in utilities, was concerned with the teaching of higher level cognitive skills. The analysis of results from the writing and use of the three programs indicates the strengths and weaknesses of each of the three types when used for CAL. It is clear that further facilities are required which are not provided by any of the three; however, it is also concluded that the field is not sufficiently mature for an attempt to be made to provide any one language which will meet all needs.

description: We study families of open chaotic maps that classically share the same asymptotic properties -- forward and backwards trapped sets, repeller dimensions, escape rate -- but differ in their short time behavior. When these maps are quantized we find that the fine details of the distribution of resonances and the corresponding eigenfunctions are sensitive to the initial shape and size of the openings. We study phase space localization of the resonances with respect to the repeller and find strong delocalization effects when the area of the openings is smaller than $\hbar$.

description: Anomalies in the temperature dependences of the recoil-free factor, f, and the average center shift, , measured by 57-Fe Mossbauer Spectroscopy, were observed for the first time in the archetype of the σ-phase alloys system, Fe-Cr. In both cases the anomaly started at the temperature close to the magnetic ordering temperature, and in both cases it was indicative of lattice vibrations hardening. As no magnetostrictive effects were found, the anomalies seem to be entirely due to a spin-phonon coupling. The observed changes in f and in were expressed in terms of the underlying changes in the potential, ΔE_p, and the kinetic energy, ΔE_k, respectively. The former, with the maximum value larger by a factor of six than the latter, decreases, while the latter increases with T. The total mechanical energy change, ΔE, was, in general, not constant, as expected for the Debye-like vibrations, but it resembled that of ΔE_p. Only in the range of 4-15 K, ΔE was hardly dependent on T.

description: The phase diagrams of EuFe$_{2-x}$Co$_x$As$_2$ $(0 \leq x \leq 0.4)$ and EuFe$_2$As$_{2-y}$P$_y$ $(0 \leq y \leq 0.43)$ are investigated by Eu$^{2+}$ electron spin resonance (ESR) in single crystals. From the temperature dependence of the linewidth $ΔH(T)$ of the exchange narrowed ESR line the spin-density wave (SDW) $(T < T_{\rm SDW})$ and the normal metallic regime $(T > T_{\rm SDW})$ are clearly distinguished. At $T > T_{\rm SDW}$ the isotropic linear increase of the linewidth is driven by the Korringa relaxation which measures the conduction-electron density of states at the Fermi level. For $T < T_{\rm SDW}$ the anisotropy probes the local ligand field, while the coupling to the conduction electrons disappears. With increasing substitution $x$ or $y$ the transition temperature $T_{\rm SDW}$ decreases linearly accompanied by a linear decrease of the Korringa-relaxation rate from 8 Oe/K at $x=y=0$ down to 3 Oe/K at the onset of superconductivity at $x \approx 0.2$ or at $y \approx 0.3$, above which it remains nearly constant. Comparative ESR measurements on single crystals of the Eu diluted SDW compound Eu$_{0.2}$Sr$_{0.8}$Fe$_2$As$_2$ and superconducting (SC) Eu$_{0.22}$Sr$_{0.78}$Fe$_{1.72}$Co$_{0.28}$As$_2$ corroborate the leading influence of the ligand field on the Eu$^{2+}$ spin relaxation in the SDW regime as well as the Korringa relaxation in the normal metallic regime. Like in Eu$_{0.5}$K$_{0.5}$Fe$_2$As$_2$ a coherence peak is not detected in the latter compound at $T_{\rm c}=21$ K, which is in agreement with the expected complex anisotropic SC gap structure.

description: We investigate open string theory on backreacting D3-branes using a spacetime approach. We study in detail the half-BPS supergravity solutions describing open strings ending on D3-branes, in the near horizon of the D3-branes. We recover quantitatively several non-trivial features of open string physics including the appearance of D3-brane spikes, the polarization of fundamental strings into D5-branes, and the Hanany-Witten effect. Finally we detail the computation of the gravitational potential between two open strings, and contrast it with the holographic computation of Wilson lines. We argue that the D-brane backreaction has a large influence on the low-energy gravity, which may lead to experimental tests for string theory brane-world scenarios.

description: The transport of fluid and electrolytes across mammalian and amphibian gallbladder has been studied extensively as the gallbladder mucosa concentrates hepatic bile 8-10 fold yet bile remains isotonic to plasma. There is a net absorption of NaCl and NaHCO3 , whereas organic components like bile salts are retained against high concentration gradients. Active transport of Na+ and er is essential to the normal concentrating function of the gallbladder. The concentrated bile in this organ provides biological detergents for fat absorption in the duodenum and changes the physicochemical properties predisposing to nucleation of cholesterol from bile and hence gallstone formation. NaCl is believed to be absorbed by electroneutral coupled cotransport; Na+ is extruded across the basolateral membrane by the sodium pump (Na+-??-ATPase). An alternative double-exchange mechanism has been postulated (Na+ /H+ and c1· /HCO3 ·). Water movement is passive, following the osmotic gradients established by active electrolyte absorption. The normal regulation of Na+ and fluid absorption is poorly understood. Two candidate gut peptides were examined: secretin, which stimulates ductular bile flow in dogs, and VIP, which is thought to mediate secretion in cholecystitis. Both peptides act through cAMP. The Ussing chamber technique was used to assess transport in the gallbladder of the guinea pig. Using 22Na+ , sodium transport and short-circuit current (lsc) were measured and results plotted as a function of log doses of each peptide. The unstirred water layer, an important barrier to transport, was also quantitated.

Development of a Self-Efficacy Scale for Teachers Who Teach Kids With Autism Spectrum Disorder

description: This study aimed to measure teachers’ self-efficacy for teaching students with autism spectrum disorder (ASD). Teacher self-efficacy refers to the belief teachers hold about their ability to affect student learning and has been shown to change teachers’ motivation, stress levels, and amount of given effort (Klassen, Tze, Betts, & Gordon, 2011). Numerous studies have dealt with the measurement of this construct and developed measures that assess teachers in different domains and populations; however, only one study (Ruble, Toland, Birdwhistell, McGrew, & Usher, 2013) has attempted to measure within the population of students with ASD. The purpose of the current study was to develop and pilot a new measure, the Teacher Self-Efficacy for Autism Scale (TSEAS), expand the construct to the target population, and provide sources of validity evidence. Results indicated that the TSEAS represented a unidimensional scale and latent correlation analyses suggested that the TSEAS has a positive correlation with a well-known teacher self-efficacy measure and has a low, positive correlation with a job satisfaction instrument. With continued refinement, the TSEAS can support others who wish to measure this construct and future application of the methods employed in building this scale can be applied to other scales with minor revisions.

description: The relation between liquid-liquid phase transitions and waterlike density anomalies in core-softened potentials of fluids was investigated in an exactly solvable one dimensional lattice model and a in a three dimensional fluid with fermi-like potential, the latter by molecular dynamics. Both systems were shown to present three liquid phases, two liquid-liquid phase transitions closely connected to two distinct regions of anomalous density increase. We propose that an oscillatory behavior observed on the thermal expansion coefficient as a function of pressure can be used as a signature of the connection between liquid-liquid phase and density.

description: Gene mapping is a very active area of research in human genetics. This effort is still in its infancy, with less than 2% of the expected gene complement having been mapped to chromosomes. Recent advances in DNA technology that permit the detection of DNA sequence variations, should provide the large number of highly polymorphic loci necessary to map the total human genome with high resolution. Isolation of new DNA clones that recognize highly polymorphic loci constitutes an important component of the gene mapping process. Based on its size, chromosome 9 is relatively underrepresented in terms of the available number of DNA markers. This fact, coupled with the tentative localization of the gene responsible for tuberous sclerosis, provided the incentive to attempt to isolate new chromosome 9 DNA markers. Library screening methods using oligonucleotide probes and competitive hybridization similar to those used for cosmid libraries were successfully employed to isolate a highly polymorphic marker from an unamplif ied human total genomic lambda library. Though this study failed in its attempt to isolate new highly polymorphic chromosome 9 markers from two chromosome 9-enriched lambda libraries, these studies reiterated the importance of constructing and maintaining lambda libraries with recombination deficient hosts which do not select against the repetitive sequences associated with these loci. This study demonstrates that unamplified lambda libraries can be used as a source of DNA clones that recognize variable number tandem repeat loci and defines parameters for the selection of appropriate libraries and efficient isolation of new highly polymorphic DNA markers.

description: One of the proposed solutions for improving the scalability of semantics of programming languages is Component-Based Semantics, introduced by Peter D. Mosses. It is expected that this framework can also be used effectively for modular meta theoretic reasoning. This paper presents a formalization of Component-Based Semantics in the theorem prover Coq. It is based on Modular SOS, a variant of SOS, and makes essential use of dependent types, while profiting from type classes. This formalization constitutes a contribution towards modular meta theoretic formalizations in theorem provers. As a small example, a modular proof of determinism of a mini-language is developed.

description: This thesis takes an alternative approach to understanding the South's proposal for a new international economic order (NIEO). Throughout the history of the development of the new order ideal (1955-19 8 0) , many s cho la rs and statesmen took a narrow approach to understanding the NIEO, concentrating mainly on an economic analysis of Southern proposals for changes in the international economic arena. This thesis questions such a narrow focus on the NIEO and suggests that a multi-dimensional approach is required, one that understands the NIEO as a Southern effort to replace the structure and functioning of the old order with a new one based on the political, institutional, and legal re-ordering of international relations. The evidence demonstrates that while the development of the NIEO concept as a plan for the future of world politics was unsystematic, the elements of what constitutes an order are present within the NIEO. Drawing on the declarations, resolutions, and statements and speeches of Third World leaders and representatives, this thesis arranges the variety of Southern concepts, ideals, and assumptions into a potentially coherent political construct, and outlines a theory of world politics for the NIEO. Having completed this exercise, the thesis critically assesses the viability of the new order ideal and examines some sig:nificant internal tensions in the theory. Upon analysis, the viability of the NIEO as a plan for the future of international relations, is questionable.

description: We present a mesoscopic approach to granular crystal dynamics, which comprises a three-dimensional finite-element model and a one-dimensional regularized contact model. The approach investigates the role of vibrational-energy trapping effects in the dynamic behavior of one-dimensional chains of particles in contact (i.e., granular crystals), under small to moderate impact velocities. The only inputs of the models are the geometry and the elastic material properties of the individual particles that form the system. We present detailed verification results and validate the model comparing its predictions with experimental data. This approach provides a physically sound, first-principle description of dissipative losses in granular systems.

description: Added mass and damping factors for lateral vibrational motion and precessional (whirl) motion of a cylindrical beam, surrounded by a viscous fluid annulus, are obtained in the first approximation by solving the linearized Navier-Stokes equations in a two dimensional flow field. The dynamic responses of the cylindrical beams are then predicted analytically. Results of some experiments on simply supported and free-free beams excited by a lateral harmonic driving force are compared with theoretical prediction. Forced response of well-casings surrounded by cement-slurry is determined theoretically. The response parameters so obtained are compared with those required for fresh-concrete consolidation available in the literature. Further, the forces, and hence vibrators that can generate these casing-response parameters are specified.

description: We employed femtosecond time- and angle-resolved photoelectron spectroscopy to analyze the response of the electronic structure of the 122 Fe-pnictide parent compounds Ba/EuFe_2As_2 and optimally doped BaFe_{1.85}Co_{0.15}As_2 near the Γpoint to femtosecond optical excitation. We identify pronounced changes of the electron population within several 100 meV above and below the Fermi level, which we explain as combination of (i) coherent lattice vibrations, (ii) a hot electron and hole distribution, and (iii) transient modifications of the chemical potential. The response of the three different materials is very similar. In the Fourier transformation of the time-dependent photoemission intensity we identify three modes at 5.6, 3.3, and 2.6 THz. While the highest frequency mode is safely assigned to the A_{1g} mode, the other two modes require a discussion in comparison to literature. The time-dependent evolution of the hot electron distribution follows a simplified description of a transient three temperature model which considers two heat baths of lattice vibrations, which are more weakly and strongly coupled to transiently excited electron population. Still the energy transfer from electrons to the strongly coupled phonons results in a rather weak, momentum-averaged electron-phonon coupling quantified by values for λ between 30 and 70 meV^2. The chemical potential is found to present a transient modulation induced by the coherent phonons. This change in the chemical potential is particularly strong in a two band system like in the 122 Fe-pnictide compounds investigated here due to the pronounced variation of the electrons density of states close to the equilibrium chemical potential.

Ovid's Amores and Ars Amatoria: some shared themes

subject: Ovid, 43 B.C. - 17 or 18 A.D. Amores
subject: Ovid, 43 B.C. - 17 or 18 A.D. Ars Amatoria

description: Bibliography: p. 109 - 112.
description: This thesis examines aspects of the relationship that exists between the Amores and the Ars Amatoria. The fact that Ovid intended this relationship between the poems to be noticed and appreciated is observed, and that Ovid's re-use of his own material from the Amores in the Ars is part of a deliberate motif which underlines his declaration that it is experience that moves his work. Ovid's treatment of five major topics (the Circus, the Dinner-Party, Hair, Guarded Love, and the Lena) is analysed in detail in separate chapters, and other themes and topics that recur throughout the poems are also covered, although in less detail, within the Introduction and Conclusion. Ovid's persona as a lover/poet in the Amores and its transition to that of teacher/poet in the Ars is also taken into consideration, and the fact that humour and didactic-which are such important elements in the Ars-are already present in the Amores.

description: A switched capacitor cyclic algorithmic converter circuit is presented. The cirÂ­cuit is capable of performing both digital to analog and analog to digital conversions using a number of published algorithms. Error sources that limit converter resolution are investigated and circuit designs that minimize these errors are described. Test reÂ­sults from an integrated CMOS prototype indicate that the simpler algorithms outperÂ­form schemes that attempt to compensate for circuit nonidealities.

description: An important challenge for ubiquitous computing is the development of techniques that can characterize a location vis-a-vis the richness and diversity of urban settings. In this paper we report our work on correlating urban pedestrian flows with Google search queries. Using longitudinal data we show pedestrian flows at particular locations can be correlated with the frequency of Google search terms that are semantically relevant to those locations. Our approach can identify relevant content, media, and advertisements for particular locations.

Generating zeta with non-Abelian Vector Fields

description: In this paper the generation of the primordial curvature perturbation by vector fields of general non-Abelian groups is discussed. We show that non-Gaussianity of the perturbation is dominated by contributions from superhorizon evolution of fields. Also we find that non-Abelian vector fields of reasonably large groups can generate the total of the curvature perturbation without violating observational constraints on the angular modulation of the spectrum.

Towards a Framework for Assessing the Impact of Cadastral Development on Land Rights-Holders

description: Although there is a published lack of accepted frameworks and methodologies for the comparison
and evaluation of national land administration systems, several frameworks for assessing the
performance of LAS in terms of different aspects of these systems have been proposed. The bulk
are biased towards analysis of technical, institutional, or cost/benefit aspects, or focus on economic
efficiency and effectiveness. There is a dearth of frameworks for evaluating the external impact of
land administration and cadastral developments, i.e. how do these developments affect citizens and
communities having rights in land?
This paper constitutes a review of recently published frameworks related to land administration and
cadastral development. The underlying theories are explored and frameworks are identified as
belonging to two general groups: those providing recommendations or guidelines, and those
providing a hierarchical analysis that conforms to the general structure of evaluation frameworks.
This latter category is further explored in terms of the motivations for development of the
framework and three sub-groups are identified: those that address a gap in knowledge, those that
address issues related specifically to developing contexts, and those with a pro-poor and good
governance focus.
Finally key lessons are drawn from the reviewed publications. It is proposed that land
administration systems should be developed in such a way that they can become successful,
sustainable, and significant. To this end good leadership is seen as very important, as are public
participation, the (temporary) adoption of fit-for-purpose standards, a focus on providing secure
tenure, and good governance. The theoretical underpinning for development should be adaptation or
unified theories, not formalisation or replacement theory
A Cluster of Class I/f/II YSOs Discovered Near the Cepheid SU Cas

description: Preliminary constraints are placed on a cluster of YSOs (J2000 02:54:31.4 +69:20:32.5) discovered in the field of the classical Cepheid SU Cas. WISE 3.4, 4.6, 12, and 22 um images reveal that the cluster deviates from spherical symmetry and exhibits an apparent diameter of 3x6'. SEDs constructed using 2MASS Ks (2.2 um) and WISE photometry indicate that 19 (36%) class I, 21 (40%) class f, and 13 (25%) class II objects lie r<3' from the cluster center. Conversely, 11 (18%) class I, 13 (21%) class f, and 37 (61%) class II objects were detected for r>3'. Approximately 50% of the class I sources within r<3' were classified solely using WISE photometry owing to the absence of detections by 2MASS.

Rigidity percolation on the square lattice

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The square lattice with central forces between nearest neighbors is isostatic with a subextensive number of floppy modes. It can be made rigid by the random addition of next-nearest neighbor bonds. This constitutes a rigidity percolation transition which we study analytically by mapping it to a connectivity problem of two-colored random graphs. We derive an exact recurrence equation for the probability of having a rigid percolating cluster and solve it in the infinite volume limit. From this solution we obtain the rigidity threshold as a function of system size, and find that, in the thermodynamic limit, there is a mixed first-order-second-order rigidity percolation transition at the isostatic point.

Regular Expression Matching and Operational Semantics
Creators: name: Rathnayake, Asiri
name: Thielecke, Hayo
Publisher: name: arXiv
Year: 2011
Subjects: subject: Logic in Computer Science (cs.LO)
subject: FOS: Computer and information sciences

description: Many programming languages and tools, ranging from grep to the Java String library, contain regular expression matchers. Rather than first translating a regular expression into a deterministic finite automaton, such implementations typically match the regular expression on the fly. Thus they can be seen as virtual machines interpreting the regular expression much as if it were a program with some non-deterministic constructs such as the Kleene star. We formalize this implementation technique for regular expression matching using operational semantics. Specifically, we derive a series of abstract machines, moving from the abstract definition of matching to increasingly realistic machines. First a continuation is added to the operational semantics to describe what remains to be matched after the current expression. Next, we represent the expression as a data structure using pointers, which enables redundant searches to be eliminated via testing for pointer equality. From there, we arrive both at Thompson's lockstep construction and a machine that performs some operations in parallel, suitable for implementation on a large number of cores, such as a GPU. We formalize the parallel machine using process algebra and report some preliminary experiments with an implementation on a graphics processor using CUDA.

Thermodynamics of mono and di-vacancies in barium titanate
Creators: name: Erhart, Paul
name: Albe, Karsten
Publisher: name: arXiv
Year: 2012
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: The thermodynamic and kinetic properties of mono and di-vacancy defects in cubic (para-electric) barium titanate are studied by means of density-functional theory calculations. It is determined which vacancy types prevail for given thermodynamic boundary conditions. The calculations confirm the established picture that vacancies occur in their nominal charge states almost over the entire band gap. For the dominating range of the band gap the di-vacancy binding energies are constant and negative. The system, therefore, strives to achieve a state in which under metal-rich (oxygen-rich) conditions all metal (oxygen) vacancies are bound in di-vacancy clusters. The migration barriers are calculated for mono-vacancies in different charge states. Since oxygen vacancies are found to readily migrate at typical growth temperatures, di-vacancies can be formed at ease. The key results of the present study with respect to the thermodynamic behavior of mono and di-vacancies influence the initial defect distribution in the ferroelectric phases and therefore the conditions for aging.

Renormalizability conditions for almost-commutative geometries
Creators: name: van Suijlekom, Walter D.
Publisher: name: arXiv
Year: 2012
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We formulate conditions for almost-commutative (spacetime) manifolds under which the asymptotically expanded spectral action is renormalizable. These conditions are of a graph-theoretical nature, involving the Krajewski diagrams that classify such geometries. This applies in particular to the Standard Model of particle physics, giving a graph-theoretical argument for its renormalizability. A promising potential application is in the selection of physical (renormalizable) field theories described by almost-commutative geometries, thereby going beyond the Standard Model.
