In the automotive industry, cost effective methods for predictive maintenance are increasingly in demand. The traditional approach for developing diagnostic methods on commercial vehicles is heavily based on knowledge of human experts, and thus it does not scale well to modern vehicles with many components and subsystems. In previous work we have presented a generic self-organising approach cal...

Entropy bounds render quantum corrections to the cosmological constant Λ finite. Under certain assumptions, the natural value of Λ is of order the observed dark energy density ∼ 10 −10 eV 4 , thereby resolving the cosmological constant problem. We note that the dark energy equation of state in these scenarios is w ≡ p/ρ = 0 over cosmo-logical distances, and is strongly disfavored by observation...

We show that in the framework of the classical general relativity the presence of a positive cosmo-logical constant implies the existence of a minimal mass and of a minimal density in nature. These results rigorously follow from the generalized Buchdahl inequality in the presence of a cosmological constant.

We have used the COSMO-RS implicit solvation method to calculate the equilibrium constants, pKa, for deprotonation of the acidic residues of the ovomucoid inhibitor protein, OMTKY3. The root mean square error for comparison with experimental data is only 0.5 pH units and the maximum error 0.8 pH units. The results show that the accuracy of pKa prediction using COSMO-RS is as good for large biom...

Synthetic aperture radar (SAR) interferometry is a powerful technology for detection and monitoring of slow terrain movements. Extraction of this information is a complex task. The persistent scatterer pair (PSP) approach was recently proposed to overcome limitations of standard persistent scatter interferometry. The PSP method exploits only the relative properties of neighboring points to avoi...

We refine the simulation technique introduced in (Di Cosmo and Kesner 1997) to show strong normalization of λ-calculi with explicit substitutions via termination of cut elimination in proof nets (Girard 1987). We first propose a notion of equivalence relation for proof nets that extends the one in (Di Cosmo and Guerrini 1999), and we show that cut elimination modulo this equivalence relation is...

We use Cosmo, a modern concurrent separation logic, to formally specify and verify an implementation of multiple-producer multiple-consumer queue in the setting Multicore OCaml weak memory model. view this result as demonstration experimental verification manner which Cosmo allows modular formal reasoning about advanced data structures. In particular, we show how joint logically atomic triples ...

By the practical success of the COSMO-RS fluid phase thermodynamics model [1,2] in many areas of chemistry, the COSMO polarization charge densities s have been proven to be excellent descriptors for the quantification of the most important kinds of molecular interactions in the liquid phase, as polar interactions, hydrogen bonding and hydrophobicity. In several comparisons and blind tests COSMO...
