Building the effective HPC resilience mechanisms required for viability of next generation supercomputers will require in depth understanding of system and component behaviors. Our goal is to build an integrated framework for high fidelity long term information storage, historic and run-time analysis, algorithmic and visual information exploration to enable system understanding, timely failure ...

The aim of this contribution is to show how the Ftransform technique can be generalized from the case of constant components to the case of polynomial components. For this purpose, we choose complete functional spaces with inner products. After a general presentation of Fm-transform where m ≥ 0, a detailed characterization of the F -transform is given. We applied a technique of numeric integrat...

The C library libkww provides functions to compute the Kohlrausch–Williams– Watts function, i.e., the Laplace–Fourier transform of the stretched (or compressed) exponential function exp(−t) for exponents β between 0.1 and 1.9 with double precision. Analytic error bounds are derived for the low and high frequency series expansions. For intermediate frequencies, the numeric integration is enormou...

Robust and computationally efficient numeric algorithms are required to simulate the sintering process of complex ceramic components by means finite element method. This work focuses on a thermodynamically consistent model capturing effects both, viscosity elasticity, within standard dissipative framework. In particular, temporal integration several implicit first second order accurate one step...

Nowadays, it is a common practice to use several educational systems in one domain. In this situation, each of the systems should be able to provide the best user modeling based on the integrated data about the user. However, differences in domain conceptualization complicate the ability of the systems to understand each other’s user models and necessitate the use of labor intensive and time co...

We consider the problem of developing O(N) scaling grid based operations needed in many central operations when performing electronic structure calculations with numeric atomcentered orbitals as basis functions. We outline the overall formulation of localized algorithms, and specifically the creation of localized grid batches. The choice of the grid partitioning scheme plays an important role i...

The Swedish national effort to program a team of Sony Legged Robots is described. Each robot uses a layered architecture for real-time situation assessment and decision making, inspired by the Thinking Cap and the Saphira architectures. Context-dependent blending simplifies the integration of higher-level, symbolic deliberation processes and lower level, and numeric control processes. Basic beh...

Arctic Options: Holistic Integration for Arctic Coastal-Marine Sustainability is a new three-year research project to assess future infrastructure associated with the Arctic Ocean regarding: (1) natural and living environment; (2) built environment; (3) natural resource development; and (4) governance. For the assessments, Arctic Options will generate objective relational schema from numeric da...

Results on approximate deduction in the context of the calculus of evidence of Dempster-Shafer and the theory of interval probabilities are reported. Approximate conditional knowledge about the truth of conditional propositions was assumed available and expressed as sets of possible values (actually numeric intervals) of conditional probabil­ ities. Under different interpretations of this condi...
