This article focuses on learning a model of system dynamics online, while satisfying safety constraints. Our objective is to avoid offline identification or hand-specified models and allow safely autonomously estimate adapt its own during operation. Given streaming observations the state, we use Bayesian obtain distribution over dynamics. Specifically, propose new matrix variate Gaussian proces...

Single farming systems (SFS) such as monocultures may negatively affect soil structural quality. This study tested the hypothesis that integrated (IFS), i.e., combination of cropping and forestry and/or livestock farming, improves quality, root development organic carbon. An experimental area was set up in 2012 at Canguiri farm belonging to Federal University Paraná, Southern Brazil. The soils ...

Corynespora cassiicola is an Ascomycetes fungus with a broad host range and diverse life styles. Mostly known as a necrotrophic plant pathogen, it has also been associated with rare cases of human infection. In the rubber tree, this fungus causes the Corynespora leaf fall (CLF) disease, which increasingly affects natural rubber production in Asia and Africa. It has also been found as an endophy...

The robust stabilization problem of chaos suppression for permanent magnet synchronous motors (PMSM) drive system is investigated in presence of parametric uncertainties. Based on control Lyapunov function (CLF) approach, a new state feedback controller is designed to realize the state of the system globally asymptotically stable. The stability of the proposed control scheme is verified via Lya...

In this paper, we propose a control Lyapunov function based on a nonlinear controller for a turbocharged diesel engine. A model-based approach is used which predicts the experimentally observed engine performance for a biodiesel. The basic idea is to develop an inverse optimal control and to employ a Lyapunov function in order to achieve good performances. The obtained controller gain guarantee...

In the title compound, C(6)H(4)ClF(3)N(2), an inter-mediate in the synthesis of the fungicide fluazinam, the F atoms of the trifluoro-methyl group are disordered over two sites in a 0.683 (14):0.317 (14) ratio. In the crystal structure, centrosymmetric dimers arise from pairs of N-H⋯N hydrogen bonds.

The asymmetric unit of the title compound, C(14)H(8)ClF(3)O(3), comprises two independent mol-ecules. The rings in each molecule are connected together via O-H⋯O hydrogen bonds to form classical hydrogen-bonded carb-oxy-lic acid dimers. The dihedral angles between the benzene rings are 80.7 (1) and 68.7 (1)°.

The title compound, C(17)H(19)ClF(3)NO, crystallizes with three mol-ecules in the asymmetric unit. The aromatic ring makes dihedral angles of 38.69 (13), 46.68 (12) and 50.52 (11)° with the plane of the cyclo-propane ring in the three mol-ecules. The crystal packing is stabilized by inter-molecular N-H⋯O hydrogen bonds.

In the mol-ecule of the title compound, C(15)H(12)ClF(2)NO(3), the quinoline ring system is not planar, the dihedral angle between the pyridine and benzene rings being 3.55 (8)°. In the crystal, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into layers parallel to (101).
