Computer-aided stress field analysis of discontinuity concrete regions
(2018)Computational Modelling of Concrete Structures: Proceedings of the Conference on Computational Modelling of Concrete and Concrete Structures (EURO-C 2018)Strut-and-tie models and stress fields are widespread methods in engineering practice for the design of dis-continuity regions. They are powerful tools that give the engineer control over the design, but they are not di-rectly applicable for checking serviceability criteria and their use for the dimensioning of real-life structures of-ten requires tedious iterative hand calculations. This paper presents a method for the design and assessment ...Conference Paper -

Improving Map Reading with Gaze-Adaptive Legends
(2018)Complex information visualizations, such as thematic maps, encode information using a particular symbology that often requires the use of a legend to explain its meaning. Traditional legends are placed at the edge of a visualization, which can be difficult to maintain visually while switching attention between content and legend.Moreover, an extensive search may be required to extract relevant information from the legend. In this paper ...Conference Paper -

The Joint Impact of Supply Chain Integration Practices on Construction
(2018)Construction Research Congress 2018Construction project teams are increasingly embracing supply chain integration practices (SCIPs) for complex projects. These SCIPs utilize formal or informal mechanisms that allow multiple actors and firms to collaborate together for the overall benefit of the project. This paper looks at the joint impact of four of these SCIPs—early involvement of key stakeholders, co-located project teams, multi-party contracts, and the last planner ...Conference Paper -

A lattice calculation of the hadronic vacuum polarization contribution to (g – 2)µ
(2018)EPJ Web of ConferencesWe present results of calculations of the hadronic vacuum polarisation contribution to the muon anomalous magnetic moment. Specifically, we focus on controlling the infrared regime of the vacuum polarisation function. Our results are corrected for finite-size effects by combining the Gounaris-Sakurai parameterisation of the timelike pion form factor with the Lüscher formalism. The impact of quark-disconnected diagrams and the precision ...Conference Paper -
Topological susceptibility under gradient flow
(2018)EPJ Web of ConferencesWe study the impact of the Gradient Flow on the topology in various models of lattice field theory. The topological susceptibility Xt is measured directly, and by the slab method, which is based on the topological content of sub-volumes (“slabs”) and estimates Xt even when the system remains trapped in a fixed topological sector. The results obtained by both methods are essentially consistent, but the impact of the Gradient Flow on the ...Conference Paper -
Medium effects and parity doubling of hyperons across the deconfinement phase transition
(2018)EPJ Web of ConferencesWe analyse the behaviour of hyperons with strangeness S = –1,–2,–3 in the hadronic and quark gluon plasma phases, with particular interest in parity doubling and its emergence as the temperature grows. This study uses our FASTSUM anisotropic Nf = 2+1 ensembles, with four temperatures below and four above the deconfinement transition temperature, Tc. The positive-parity groundstate masses are found to be largely temperature independent ...Conference Paper -
Improved convergence of Complex Langevin simulations
(2018)EPJ Web of ConferencesThe sign problem appears in lattice QCD as soon as a non-zero chemical potential is introduced. This prevents direct simulations to determine the phase structure of the strongly interacting matter. Complex Langevin methods have been successfully used for various models or approximations of QCD. However, in some scenarios it converges to incorrect results. We present developments of our new method that helps to improve the convergence by ...Conference Paper -
Alternatives to the stochastic "noise vector" approach
(2018)EPJ Web of ConferencesSeveral important observables, like the quark condensate and the Taylor coefficients of the expansion of the QCD pressure with respect to the chemical potential, are based on the trace of the inverse Dirac operator and of its powers. Such traces are traditionally estimated with “noise vectors” sandwiching the operator. We explore alternative approaches based on polynomial approximations of the inverse Dirac operator.Conference Paper -

Kinematic Determination Of GNSS Orbits Including Clock Modeling
(2018)Modern orbital products from the International GNSS Service (IGS) analysis centers are based on dynamic orbit models including a variety of perturbation forces. It is well-known that the errors caused by modeling deficiencies are propagating into further products like satellite clock corrections, station coordinates, Earth rotation parameters (ERP) and troposphere zenith delays, producing artifacts in the time series at the draconitic ...Conference Paper
