This paper aims to study the efficiency of energy dissipators, both fluid viscous and hysteretic, improve seismic responses buildings. To quantify ability dissipators reduce responses, a series time history analyzes were carried out on simplified models Said consist masses springs with linear elastic behavior whose properties are obtained from shear beam model, joined by link elements non-linea...

We consider a time-dependent small quantum system weakly coupled to an environnement, whose effective dynamics we address by means of Lindblad equation. assume the Hamiltonian part Lindbladian is slowly varying in time and dissipator has amplitude. study properties evolved state as adiabatic parameter coupling constant both go zero, various asymptotic regimes. In particular, analyse deviations ...

We develop a general theory describing the thermodynamical behavior of open quantum systems coupled to thermal baths beyond perturbation theory. Our approach is based on exact time-local master equation for reduced open-system states, and principle minimal dissipation. This leads unique prescription decomposition into Hamiltonian part representing coherent time evolution dissipator dissipation ...

In this paper we consider a quantum open system and treat the master equation with some restricted dissipator which consists of a set of projection operators (projectors). The exact solution is given under the commutable approximation (in our terminology). This is the first step for constructing a general solution. In this paper we revisit dynamics of a quantum open system. First of all we expl...

This paper presents a simulation based on the boundary element method for optimization of thermomechanical behavior three-dimensional microchip-dissipator packaging when heat generation produced is medium-low. Starting from basic architecture studied in literature, different modifications affecting both elastic conditions and contact interface between microprocessor heatsink are included order ...

The seismic-resistant structure is required for the earthquake-hazard area. One of systems Concentrically Braced Frame (CBF), which was established to diminish seismic damage. At time implementation, CBF reduces horizontal deformations building so that failure as well heavy damage can be avoided. In CBF, brace energy dissipator, whose performance needs enhanced. This study discussed structural ...

The performance of precast concrete frame structures against seismic loads mainly depends on the beam-to-column connection. A ductile hybrid connection consists unbonded post-tensioning steel and bonded reinforcement bars, both which provide overall moment resistance to frame. Post-tensioning acts as a restoring force brings structure back its initial position upon unloading. Mild an energy dis...

BACKGROUND The morphopathological picture of a subset of equine myopathies is compatible with a primary mitochondrial disease, but functional confirmation in vivo is still pending. The cationic dye JC-1 exhibits potential-dependent accumulation in mitochondria that is detectable by a fluorescence shift from green to orange. As a consequence, mitochondrial membrane potential can be optically mea...
