description: In integrated circuit design scheduling plays an important role in determining the overall performance of a high-level synthesis system. This thesis addresses the design of an efficient algorithm to solve the scheduling problem. The traditional integer linear programming (ILP) approach handles the scheduling problem with the combination of the number of input operations and scheduling steps. In this method, the number of input variables is a product of operations and scheduling steps of each operation. Since the valid scheduling steps depend heavily on the timing constraints of the scheduling problem, the input variables and thus the computing time grow drastically as the timing limits increase. An efficient scheduling model based on the binary decision diagram (BDD) is presented. In this approach, data dependent operations in the scheduling problem are handled as a coherent group. Therefore, many redundant variables and constraint equations in ILP formulation are removed. This has significantly improved the efficiency of previous IPL scheduling computation. The experiment results show that ILP variables and equations have been reduced by approximately 10% to 30% in our scheduling model. The advantages of this method become more evident in solving large and complicated scheduling problems.

description: We present the "endpoint" formalism for the calculation of electromagnetic radiation and illustrate its applications in astroparticle physics. We use the formalism to explain why the coherent radiation from the Askaryan effect is not in general Cherenkov radiation, as the emission directly results from the time-variation of the net charge in the particle shower. Secondly, we illustrate how the formalism has been applied in the air shower radio emission code REAS3 to unify the microscopic and macroscopic views of radio emission from extensive air showers. Indeed, the formalism is completely universal and particularly well-suited for implementation in Monte Carlo codes in the time- and frequency-domains. It easily reproduces well-known "classical mechanisms" such as synchrotron radiation, Vavilov-Cherenkov radiation and transition radiation in the adequate limits, but has the advantage that it continues to work in realistic, complex situations, where the "classical mechanisms" tend to no longer apply and adhering to them can result in misleading interpretations.

description: A modified replication was conducted of a 1988 study which aimed to determine the best strategies for promoting a female social work student's interest in a career in administration. The original study, using a survey research design, determined that encouragement from a mentor(s) followed by consciousness­raising were the two best strategies for promoting a female social work student's interest in a career in administration. The replication was modified only slightly with the inclusion of two additional independent variables. Some of the replication findings did concur with the original study, particularly among variables which appear not to be significant predictors of a female social work student's interest in an administrative career. however, encouragement from peers/colleagues was found in the replication to be more important than encouragement from mentors or consciousness-raising. One firm conclusion can be drawn from the findings of both studies - any strategy to promote interest in administration among female social workers must focus on active encouragement from as many sources of informal support as possible.

description: The paper presents a cradle-to-gate sustainability assessment methodology specifically designed to evaluate aircraft components in a robust and systematic manner. This methodology integrates multi-criteria decision-making (MCDM) analysis across ten criteria, categorized under environmental impact, cost, and performance. Environmental impact is analyzed through life cycle assessment and cost through life cycle costing, with both analyses facilitated by SimaPro software. Performance is measured in terms of component mass and specific stiffness. The robustness of this methodology is tested through various MCDM techniques, normalization approaches, and objective weighting methods. To demonstrate the methodology, the paper assesses the sustainability of a fuselage panel, comparing nine variants that differ in materials, joining techniques, and part thicknesses. All approaches consistently identify thermoplastic CFRP panels as the most sustainable option, with the geometric mean aggregation of weights providing balanced criteria consideration across environmental, cost, and performance aspects. The adaptability of this proposed methodology is illustrated, showing its applicability to any aircraft component with the requisite data. This structured approach offers critical insights to support sustainable decision-making in aircraft component design and procurement.

Gap like structure in a nonsuperconducting layered oxycarbonate Bi$_{2+x}$Sr$_{4-x}$Cu$_2$CO$_3$O$_{8+δ}$ single crystal

description: The magnetic field and temperature dependence of the in-plane tunneling conductance $dI/dV(V)$ in high-quality nonsuperconducting (down to 10 mK) layered oxycarbonate Bi$_{2+x}$Sr$_{4-x}$Cu$_2$CO$_3$O$_{8+δ}$ single crystals has been investigated using break junctions. Combining measurements of the in-plane magnetoresistivity $ρ_{ab}(T,H)$ and the magnetotunneling, we present evidence for the existence of a small "pseudogap" in a nonsuperconducting cuprate, without local incoherent pairs or any correlation phenomena associated with superconductivity. We are unable to distinguish if such a "pseudogap" is totally unrelated to superconductivity or if its existence is a necessary condition for the subsequent occurrence of superconductivity with increasing carrier density in the sample.

description: We present an experimental study of a four beam optical lattice using the light scattered by the atoms in the lattice. We use both intensity correlations and observations of the transient behavior of the scattering when the lattice is suddenly switched on. We compare results for 3 different configurations of the optical lattice. We create situations in which the Lamb-Dicke effect is negligible and show that, in contrast to what has been stated in some of the literature, the damping rate of the 'coherent' atomic oscillations can be much smaller than the inelastic photon scattering rate.

description: We present the first optical observations of the unique system J0737-3039 (composed of two pulsars, hereafter PSR-A and PSR-B). Ultra-deep optical observations, performed with the High Resolution Camera of the Advanced Camera for Surveys on board the Hubble Space Telescope could not detect any optical emission from the system down to m_F435W=27.0 and m_F606W=28.3. The estimated optical flux limits are used to constrain the three-component (two thermal and one non-thermal) model recently proposed to reproduce the XMM-Newton X-ray spectrum. They suggest the presence of a break at low energies in the non-thermal power law component of PSR-A and are compatible with the expected black-body emission from the PSR-B surface. The corresponding efficiency of the optical emission from PSR-A's magnetosphere would be comparable to that of other Myr-old pulsars, thus suggesting that this parameter may not dramatically evolve over a time-scale of a few Myr.

STUDY OF CONCRETE SOLDIER PILE FAILURE AS A SUPPORTING SYSTEM IN BASEMENT EXCAVATION
Creators: name: DEMELASH WONDIMAGEGN
Publisher: name: Zenodo
Year: 2020

description: Lack of inadequate space at urban centers goes for deep vertical excavations which require supports that are designed for minimum construction cost. Among such structures is soldier piles excavation support system, which is considered in details for this case study. To study the causes of temporary support failure, a commercial finite element analysis software plaxis 3D foundation has been used. Considering, four cases, the extreme total displacement, the effective stresses, the incremental total displacement, the active pore pressure, the extreme volumetric strain increment, and factor of safety have been analyzed with respect to the embedment depth. In order to find the main causes for the failure of concrete soldier piles, input parameters from geotechnical investigation have been used. In addition to this, site reconnaissance study has been made with eyewitnesses of different construction workers as they were present before, during and after the failure occurs. Accordingly, the study revealed that two main causes for failure of the concrete soldier piles. These are: - the seepage of water and the soil cohesion. Seepage of water was demonstrated by conducting interview as well as from seepage analysis
Automatic extraction of wall streamlines from oil-flow visualizations using a convolutional neural network

description: Oil-flow visualizations represent a simple means to reveal time-averaged wall streamline patterns. Yet, the evaluation of such images can be a time-consuming process and is subjective to human perception. In this study, we present a fast and robust method to obtain quantitative insight based on qualitative oil-flow visualizations. Using a convolutional neural network, the local flow direction is predicted based on the oil-flow texture. This was achieved with supervised training based on an extensive dataset involving approximately one million image patches that cover variations of the flow direction, the wall shear-stress magnitude and the oil-flow mixture. For a test dataset that is distinct from the training data, the mean prediction error of the flow direction is as low as three degrees. A reliable performance is also noted when the model is applied to oil-flow visualizations from the literature, demonstrating the generalizability required for an application in diverse flow configurations.
Testing Einstein's time dilation under acceleration using Mössbauer spectroscopy

description: The Einstein time dilation formula was tested in several experiments. Many trials have been made to measure the transverse second order Doppler shift by Mössbauer spectroscopy using a rotating absorber, to test the validity of this formula. Such experiments are also able to test if the time dilation depends only on the velocity of the absorber, as assumed by Einstein's clock hypothesis, or the present centripetal acceleration contributes to the time dilation. We show here that the fact that the experiment requires $γ$-ray emission and detection slits of finite size, the absorption line is broadened; by geometric longitudinal first order Doppler shifts immensely. Moreover, the absorption line is non-Lorenzian. We obtain an explicit expression for the absorption line for any angular velocity of the absorber. The analysis of the experimental results, in all previous experiments which did not observe the full absorption line itself, were wrong and the conclusions doubtful. The only proper experiment was done by Kündig (Phys. Rev. 129 (1963) 2371), who observed the broadening, but associated it to random vibrations of the absorber. We establish necessary conditions for the successful measurement of a transverse second order Doppler shift by Mössbauer spectroscopy. We indicate how the results of such an experiment can be used to verify the existence of a Doppler shift due to acceleration and to test the validity of Einstein's clock hypothesis.

Hopf-Wess-Zumino term in the effective action of the 6d, (2, 0) field theory revisted

description: We discuss the Hopf-Wess-Zumino term in the effective action of the 6d (2, 0) theory of the type A_{N-1} in a generic Coulomb branch. For such terms, the supergravity calculation could be trusted. We calculate the WZ term on supergravity side and show that it could compensate the anomaly deficit, as is required by the anomaly matching condition. In contrast with the SYM theory, in which each WZ term involves one root e_{i}-e_{j}, here, the typical WZ term involves two roots e_{i}-e_{j} and e_{k}-e_{j}. Such kind of triple interaction may come from the integrating out of the massive states carrying three indices. A natural candidate is the recently proposed 1/4 BPS objects in the Coulomb phase of the 6d (2, 0) theories. The WZ term could be derived from the field theory by the integration out of massive degrees of freedom. Without the 6d (2, 0) theory at hand, we take the supersymmetric equations for the 3-algebra valued (2, 0) tensor multiplet as the prototype to see how far we can go. The H_{3}\wedge A_{3} part of the WZ term is obtained, while the A_{3}\wedge F_{4} part, which is the term accounting for the anomaly matching, cannot be produced by the standard fermion loop integration.

description: We present the evolutionary properties and luminosity functions of the radio sources belonging to the Chandra Deep Field South VLA survey, which reaches a flux density limit at 1.4 GHz of 43 microJy at the field center and redshift ~5, and which includes the first radio-selected complete sample of radio-quiet active galactic nuclei (AGN). We use a new, comprehensive classification scheme based on radio, far- and near-IR, optical, and X-ray data to disentangle star-forming galaxies from AGN and radio-quiet from radio-loud AGN. We confirm our previous result that star-forming galaxies become dominant only below 0.1 mJy. The sub-mJy radio sky turns out to be a complex mix of star-forming galaxies and radio-quiet AGN evolving at a similar, strong rate; non-evolving low-luminosity radio galaxies; and declining radio powerful (P > 3 10^24 W/Hz) AGN. Our results suggest that radio emission from radio-quiet AGN is closely related to star formation. The detection of compact, high brightness temperature cores in several nearby radio-quiet AGN can be explained by the co-existence of two components, one non-evolving and AGN-related and one evolving and star-formation-related. Radio-quiet AGN are an important class of sub-mJy sources, accounting for ~30% of the sample and ~60% of all AGN, and outnumbering radio-loud AGN at < 0.1 mJy. This implies that future, large area sub-mJy surveys, given the appropriate ancillary multi-wavelength data, have the potential of being able to assemble vast samples of radio-quiet AGN by-passing the problems of obscuration, which plague the optical and soft X-ray bands.

description: We consider transport properties of disordered two-dimensional electron gases under high perpendicular magnetic field, focusing in particular on the peak longitudinal conductivity $σ_{xx}^\mathrm{peak}$ at the quantum Hall plateau transition. We use a local conductivity model, valid at temperatures high enough such that quantum tunneling is suppressed, taking into account the random drift motion of the electrons in the disordered potential landscape and inelastic processes provided by electron-phonon scattering. A diagrammatic solution of this problem is proposed, which leads to a rich interplay of conduction mechanisms, where classical percolation effects play a prominent role. The scaling function for $σ_{xx}^\mathrm{peak}$ is derived in the high temperature limit, which can be used to extract universal critical exponents of classical percolation from experimental data.

description: We show strong effects of a weak and smooth, on the magnetic length, superlattice potential upon edge magnetoplasmons (EMPs) at the armchair edge, with a smooth steplike electrostatic lateral confining potential, of a wide graphene channel in the $ν=2$ quantum Hall effect regime. The superlattice potential leads to essential enlargement of a number of EMPs, descend from two fundamental EMPs in the absence of superlattice. For the wave vector $k_{x}$ within the first Brillouin zone, the EMPs show as the regions of acoustical or quasi-acoustical dispersion, with a finite value of group velocity, so the regions with frequency gaps, where a group velocity is nullified at some $k_{x}$. We obtain that for $k_{x} \to 0$ only for two EMPs the frequency tends to zero as for other EMPs it obtains finite values. Strong dependence of dispersion relations of the EMPs from the period of the superlattice $a_{0}$ and the distance $d$ from a metallic gate is shown; in particular, for typical size of a gap, for characteristic value of the frequency and $k_{x}$ at which the group velocity is reduced to zero. At the frequency that corresponds to zero group velocity of pertinent fundamental EMP branch the response of the system should present a strong resonance.

In many cases, rate constants inferred from fluorescence time series exhibit nonintuitive dependence on ligand concentration. Here we examine several possible mechanistic and technical origins that may induce ligand dependence of rate constants. Using aggregated Markov models, we show under the condition of detailed balance that non-fluorescent bindings and missed events due to transient interactions, instead of conformation fluctuations, may underly the dependence of waiting times and thus apparent rate constants on ligand concentrations. In general, waiting times are rational functions of ligand concentration. The shape of concentration dependence is qualitatively affected by the number of binding sites in the single molecule and is quantitatively tuned by model parameters. We also show that ligand dependence can be caused by non-equilibrium conditions which result in violations of detailed balance and require an energy source. As to a different but significant mechanism, we examine the effect of ambient buffers that can substantially reduce the effective concentration of ligands that interact with the single molecules. To demonstrate the effects by these mechanisms, we applied our results to analyze the concentration dependence in a single-molecule experiment EGFR binding to fluorophore-labeled adaptor protein Grb2 by Morimatsu et al. (PNAS,104:18013,2007).

description: In this paper we scrutinize the concept of locally inertial reference frames (LIRF) in Lorentzian and Riemann-Cartan spacetime structures. We present rigorous mathematical definitions for those objects, something that needs preliminary a clear mathematical distinction between the concepts of observers, reference frames, naturally adapted coordinate functions to a given reference frame and which properties may characterize an inertial reference frame (if any) in the Lorentzian and Riemann-Cartan structures. We hope to have clarified some eventual obscure issues associated to the concept of LIRF appearing in the literature, in particular the relationship between LIRFs in Lorentzian and Riemann-Cartan spacetimes and Einstein's most happy though, i.e., the equivalence principle.

Efficiency Theory: a Unifying Theory for Information, Computation and Intelligence
Creators: name: Yampolskiy, Roman V.
Publisher: name: arXiv
Year: 2011
Subjects: subject: Computational Complexity (cs.CC)
subject: FOS: Computer and information sciences

description: The paper serves as the first contribution towards the development of the theory of efficiency: a unifying framework for the currently disjoint theories of information, complexity, communication and computation. Realizing the defining nature of the brute force approach in the fundamental concepts in all of the above mentioned fields, the paper suggests using efficiency or improvement over the brute force algorithm as a common unifying factor necessary for the creation of a unified theory of information manipulation. By defining such diverse terms as randomness, knowledge, intelligence and computability in terms of a common denominator we are able to bring together contributions from Shannon, Levin, Kolmogorov, Solomonoff, Chaitin, Yao and many others under a common umbrella of the efficiency theory.
Vegetation classification using Landsat TM and SPOT-HRV imagery in mountainous terrain, Kananaskis Country, southwestern Alberta

description: Landsat-5 Thematic Mapper (TM) 7-band data and SPOT-HRV 3-band data, and topographic measures derived from a digital elevation model (DEM) were used to determine the best set of classification variables for mapping vegetation communities in a mountainous region in southwestern Alberta. Ground and topographic data were gathered for 765 pixels sampled in the field. Discriminant analysis of an integrated TM+DEM data set resulted in overall accuracy of 72.77% for twenty-eight landcover classes, an improvement_ of 10.81 % over TM data alone. Discriminant analysis of a SPOT +DEM data set resulted in a similar accuracy of 73.44% for twenty-three classes, an improvement of 10.23% over SPOT data alone. Individual classes showed considerable variability in accuracy, which was reduced significantly with the addition of elevation, slope and incidence from the DEM. Most accuracy improvement occurred in poplar slope (by 60.7%), herb avalanche slope (40.9%), fen (by 28.5%) and Cassiope alpine meadow heath (by 25%) classes. Most spectrally distinct vegetated classes included mixedwood forest, herb- and pine-dominated rock outcrop complexes, several shrub-dominated communities, and burned and logged areas. Herb-dominated wetlands (fen, marsh, floating bog) were least distinct. Higher spatial resolution data (SPOT) is important in the separation of non­forested wetlands, particularly herb-dominated communities. In turn, higher spectral resolution data (TM) is important in the separation of non-forested upland classes. Integration of best classification accuracies from the two satellite data sets improved overall accuracy to 88.31 % and shows the need for further research in this area. A maximum likelihood classification and mapping of the TM data set illustrates the spatial distribution of the classes, and provides further support for statistical evidence that topographic data is necessary for landcover classification of high relief environments.

description: Bibliography: p. 241-247.
description: This work is both an Introduction to the philosophy of Bernard Lonergan and an essay in the application of his approach in the areas of contemporary epistemology and philosophy of historiography. The first Part of the work is an exposition and defence of Lonergan 's position on cognitional structure and epistemology. Attention is focused upon the way Lonergan's thought in this area compares and contrasts with recent work on epistemology and the possibility of objective knowing by such philosophers as Hintikka, Mackie, Davidson, Rorty and Wittgenstein. I defend Lonergan's attempt to argue that denials of the possibility of objective knowledge are self-referentially incoherent, and that, when properly understood, the reversal of such denials substantiates a position on cognition and epistemology. The second part of the work considers the way Lonergan builds upon his work in epistemology to outline an approach to problems concerning objectivity in the knowledge of History. After an exposition of Lonergan's thought on objectivity in historical knowledge, I proceed to examine ways in which his work in this area contributes to discussions on such issues as the criteria of selection used by historians and the place of value-judgements in historical writing. I argue that Lonergan's designation of the goal of historical writing as "understanding what was going forward in the human community in the past" is a useful one. In the final chapters of the work I employ elements from Lonergan's position to argue against some of the views put forward by Hayden White, Louis Mink and others, concerning the "subjectivity" of the historian's account of past developments. In a way akin to that of David Carr (but without Carr's dependence on Husserl) I argue that there is good evidence for the belief that reality does have an aspect to it which may be described in the "narrative" accounts of historians.
Modelling the light curves of PSR B1259-63/LS 2883-II.The effects of anisotropic pulsar wind and Doppler-boosting

description: PSR B1259-63/LS 2883 is a binary system in which a 48-ms pulsar orbits around a Be star in a high eccentric orbit with a long orbital period of about 3.4 yr. It is special for having asymmetric two-peak profiles in both the X-ray and the TeV light curves. Recently, an unexpected GeV flare was detected by $Fermi$ gamma-ray observatory several weeks after the last periastron passage. In this paper, we show that this observed GeV flare could be produced by the Doppler-boosted synchrotron emission in the bow shock tail. An anisotropic pulsar wind model, which mainly affects the energy flux injection to the termination shock in different orbital phase, is also used in this paper, and we find that the anisotropy in the pulsar wind can play a significant role in producing the asymmetric two-peak profiles in both X-ray and TeV light curves. The X-ray and TeV photons before periastron are mainly produced by the shocked electrons around the shock apex and the light curves after periastron are contributed by the emission from the shock apex and the shock tail together, which result in the asymmetric two-peak light curves.

Force localization in contracting cell layers

description: Epithelial cell layers on soft elastic substrates or pillar arrays are commonly used as model systems for investigating the role of force in tissue growth, maintenance and repair. Here we show analytically that the experimentally observed localization of traction forces to the periphery of the cell layers does not necessarily imply increased local cell activity, but follows naturally from the elastic problem of a finite-sized contractile layer coupled to an elastic foundation. For homogeneous contractility, the force localization is determined by one dimensionless parameter interpolating between linear and exponential force profiles for the extreme cases of very soft and very stiff substrates, respectively. If contractility is sufficiently increased at the periphery, outward directed displacements can occur at intermediate positions, although the edge itself still retracts. We also show that anisotropic extracellular stiffness leads to force localization in the stiffer direction, as observed experimentally.

description: We show that, for Galilean invariant quantum Hall states, the Hall viscosity appears in the electromagnetic response at finite wave numbers q. In particular, the leading q dependence of the Hall conductivity at small q receives a contribution from the Hall viscosity. The coefficient of the q^2 term in the Hall conductivity is universal in the limit of strong magnetic field.
