We studied the characteristic of reduced graphene oxide (rGO) as a counter electrode (CE) in Pt-free dye-sensitized solar cell (DSSC) using single diode model equation based on current density-voltage (J-V) measurement. The electrical characteristics of D... see more

The pure pregnancy epulis is mostly vascular, and generally shrinks or disappears with the drop in estrogen levels following delivery. However, the fibrous epulis or granulomatous epulis may enlarge rapidly in the early stages of pregnancy, necessitating ... see more

In this article, we propose the use of the optimization algorithm based on improved pattern search (IPSM), applying it to the estimation of the model parameters of a single diode of a photovoltaic cell. The parameters to be estimated are the photovoltaic ... see more

Experimental evaluation of spectral and power-current (P-I) characteristics of fiber coupled single emitter multimode laser diodes used for development of efficient pumping assembly is reported. Fiber coupled laser diodes emitting around 976 nm are best s... see more

The paper describe a computer-based method to calculate the series resistance Rs of a millimeter wave Ka-band packaged IMPATT diode from small signal conductance-susceptance characteristics. The series resistance Rs has been calculated at the threshold co... see more

Purpose: To describe a case of inferior bullous keratopathy caused by iris fibers resolved with laser diode 532.Case report: A 74-year-old woman consulted for deterioration of visual acuity in right eye, accompanied by foreign body sensation. A phacoemuls... see more

In this study, a diode characteristic testing will be conducted, namely the characteristics of forward bias and reverse bias using Multisim software. Diode components are mostly applied to electronic circuits, so a simulation is needed to determine the pe... see more

In this paper, the control of seven level diode clamped inverter with selective harmonic elimination (SHE) pulse width modulation (PWM) technique based on genetic algorithm (GA) has been developed. In standard SHE-PWM, the seven level inverters allow the ... see more

Objectives: Light irradiation and heat have been used to accelerate the process of tooth bleaching. This study aimed to assess the efficacy of conventional bleaching compared to laser-bleaching using three different wavelengths of diode lasers.Materials a... see more
