We report results of combined experimental and theoretical studies of dye-sensitized solar cells (DSSCs) using 5-(4-sulfophenylazo)salicylic acid disodium salt, known as Mordant Yellow 10 (MY-10), as TiO2 sensitizer. We focus on a single dye but vary the solvent and the pH of the solution as well...
Over the past decades, the research on structural vibration control has mainly focused on ‘energy dissipation’ strategy using various dampers for hazard mitigation. This paper proposes a novel application of linear motion electromagnetic (EM) devices, termed linear EM dampers hereinafter, for...
To achieve electronics intimately integrated on the surfaces of substrates with complex, curvilinear shapes are described. The approach exploits silicon membranes in circuit mesh structures that can be deformed in controlled ways using thin, elastomeric films. Experimental and theoretical studies...

The paper presents a state-of-the-art of the numerical modeling of the coupled problems involving heat, fluid flow and electromagnetic phenomena in electrical transformers. Mathematical descriptions of both Computational Fluid Dynamics (CFD) and electromagnetic (EMAG) models are given. Since thes...
Drawn from an analysis of experimental data and results of special studies are generalized; based on this, it is possible to estimate the advantages gained from incorporating a deaeratorless thermal circuit into the regeneration system used in modern power units.
In previous experimental studies on the visual processing in vertebrates, higher-order visual functions such as the object segregation from background were found even in the retinal stage. Previously, the "linear-nonlinear" (LN) cascade models have been applied to the retinal circuit, and succeed...
Vibrating energy is a renewable energy that can be used to power wireless transducers. This article presents analytical and numerical results that put forward design parameters for optimizing the energy conversion from mechanical vibration to electrical power with an electromagnetic transducer. T...
Results from experimental studies of the gas generation process as applied to independent power-generating installations are presented.

Research in noise and vibration control has partially focused on semi-active attenuation techniques such as switching shunt control (SSC) systems. Among the various methods, SSC architectures exhibit several interesting advantages such as low power absorption and intrinsic adaptive capabilities. ...
Impedance characteristics of the negative electrode of lead-acid battery were derived on the basis of fundamental interfacial processes occurring at the electrode. The solution of the governing equations was presented in terms of a simple equivalent circuit consisting of resistive and capacitive ...
