Analysis of 2-year corneal cross-linking results in keratoconus patients
PURPOSE To analyze the results of 2 years of corneal collagen cross-linking (CXL) for the treatment of keratoconus and to detect the efficiency of this procedure. DESIGN This was a retrospective noncomparative study. PATIENTS AND METHODS A total of 58 eyes of 40 keratoconus patients were subjected to CXL. Epithelium-off CXL was the only procedure performed for all cases. The ... Read more

Comparison of epithelium-off and transepithelial corneal collagen cross-linking for treatment of keratoconus
PURPOSE The aim of the study was to assess the safety and efficacy of epithelium-off corneal cross-linking (conventional cross-linking) versus epithelium-on cross-linking (epithelium-on cross-linking) in the treatment of keratoconus. PATIENTS AND METHODS This study was a nonrandomized comparative trial. Forty-three eyes of 35 patients were included in this study. All eyes were subjected to the preoperative and postoperative measures including ... Read more

Self-Oscillating Fly-back Converter for Mobile Batteries Charging Applications‏
The self-oscillating flyback converter is a popular circuit for cost-sensitive applications due to its simplicity and low component count. This paper presents self-oscillating fly-back converter for mobile batteries charging applications. The converter is designed to step-down the high voltage input to an acceptable level from 220 VAC to 7VDC. By adding indictor and capacitor the power factor and input currant ... Read more

Optimal allocation of renewable dg sources in distribution networks considering load growth
The annual increasing of load demand in electrical distribution networks leads to line congestion, decreasing the bus voltages below the acceptable limits and increasing the active and reactive power losses. However, renewable distributed generation (DG) has received increasing attention due to that growing in load demand. This paper presents a hybrid method based on moth-flame optimization (MFO) algorithm with loss ... Read more

Optimal siting and sizing of SSSC using improved harmony search algorithm considering non-smooth cost functions
Static Synchronous Series Compensator (SSSC) is an elegant member of Flexible Alternating Current Transmission Systems (FACTS) devices. SSSC can be used to control the active and reactive power flows of transmission lines. In this paper, improved harmony search algorithm (IHS) is applied to determine the optimal location and parameter settings of SSSC in power systems. The optimal power flow (OPF) ... Read more
