Climate change and the depletion of fossil fuels make it urgent to find an alternative oil-based fuels, especially in machines powered by internal combustion engines. Biomass is currently a poorly used source energy meets necessary conditions replace large part fuels. However, current engines cannot burn solid biomass specific engine needs be developed. This work proposes thermodynamic cycle bi...

We study the effect of the degeneracy factor in the energy levels of the well-known Landau problem for a magnetic quantum Otto engine. The scheme of the cycle is composed of two quantum adiabatic processes and two quantum isomagnetic processes driven by a quasi-static modulation of external magnetic field intensity. We derive the analytical expression of the relation between the magnetic field ...

The study proposed to analyze the combined driving cycles and their effect on fuel consumption within Distrito Metropolitano de Quito. For this, a test protocol was established where orography of land, traffic density road infrastructure District were studied. These factors allowed evaluation through global positioning system canister in order systematically travel set roads distance, time, ave...

We revisit the intrinsic differential geometry of Wasserstein space over a Riemannian manifold, due to series papers by Otto, Otto-Villani, Lott, Ambrosio-Gigli-Savaré, etc.

We analyze the entropy production and the maximal extractable work from a squeezed thermal reservoir. The nonequilibrium quantum nature of the reservoir induces an entropy transfer with a coherent contribution while modifying its thermal part, allowing work extraction from a single reservoir, as well as great improvements in power and efficiency for quantum heat engines. Introducing a modified ...

We propose an alternative conceptual design for a graphene-based quantum engine, driven by a superposition of mechanical strain and an external magnetic field. Engineering of strain in a nanoscale graphene flake creates a gauge field with an associated uniform pseudomagnetic field. The strain-induced pseudomagnetic field can be combined with a real magnetic field, leading to the emergence of di...

In the recent years, researchers developed image encryption methods based on chaotic systems. This paper proposed new image encryption technique based on new chaotic system by adding two chaotic systems: the Lorenz chaotic system and the Rössler chaotic system. The main advantage of this technique is stronger security, as is shown in the encryption tests.

We consider a quantum Otto cycle for a time-dependent harmonic oscillator coupled to a squeezed thermal reservoir. We show that the efficiency at maximum power increases with the degree of squeezing, surpassing the standard Carnot limit and approaching unity exponentially for large squeezing parameters. We further propose an experimental scheme to implement such a model system by using a single...
