Comparative Evaluation of Second-Class Lever Principle Based Single-Axis Solar Tracking System and Conventional System

“…Using (15), can be obtain the daily available energy (H ot ) of a fixed tilt. By using Equations ( 16), (17), and (18) can be obtaining the solar radiation of horizontal surface (G in ), fixed tilt surface (G Fixed ), and single axis tracker (G Track ). Figure 5 shows the energy available of the horizontal flat plate, fixed tilted plate, and the plate while tracking the sun.…”

“…Moreover, the examinations do not include a valued analysis of energy yield and power consumption of the motor driver and electronic circuits. Here, the power consumption of a tracking system has 3-10% Salient Features • SAST system works based on a programmable logic controller (PLC) • Compared to the FSA system, the daily power extracted is 20% more [6] • A Passive SAST system is Aluminium/Steel bimetallic strips are controlled with a viscous damper • Improvement in energy is 23% greater than that of the FSA system [7] • 3-position automated tracking system • Extracted power is 24.5% greater than that of the FSA system [8] • Single-axis and dual-axis automatic system • Extracted power is 18% greater than that of the FSA system [9] • PIC microcontroller based SAST system • Mean power improvement is 66.9% greater than FSA system [10] • South-east 50 • , South and Southwest 50 • 3-position SAST system • Energy extracted is 24.2% greater than FSA system [11] • Fuzzy logic-based control system • Energy extracted is 47% greater than that of the FSA system [12] • Hybrid (dual-axis + single-axis) SAST system • Energy enhancement is 25.62% higher than the FSA [13] • MPPT based low power SAST system • Energy extracted is 12-20% greater than FSA system [14] • Tripper motor based single and two-axis solar tracking system • Energy extracted is 31.67% greater than FSA system [15] • Robot arm based SAST system • Power improvement is 17.2% greater than FSA system [16] • A passive SAST system working based on liquid vapor pressure (Thinner, Methanol, and Acetone) • Power improvement is 23.33% greater than FSA system [17] • A SAST system based on a real-time clock (RTC) • Energy savings are 15-20% greater than in the FSA system [18] • Scaled down version of SAST with 15 • step movement per hour • Energy improvement is 28-43.6% greater than FSA system [19] • Sunlight intensity based 3-position SAST system • Extracted energy is 20% greater than that of the FSA system [20] • A passive SAST system works reactor with metal hydride • Energy extracted is 7.2% greater than FSA system [21] • Irradiation monitored microcontroller SAST system • Energy extracted is 40% higher than in the FSA system [22] of improved effectiveness. The sun trackers essential not need to point directly sun effectively.…”

Roux‐en‐Y Versus One Anastomosis Gastric Bypass as Redo‐Operations Following Sleeve Gastrectomy: A Retrospective Study

“…Re‐sleeving, Roux‐en‐Y gastric bypass (RYGB) and various other procedures are options [8–14]. One anastomosis gastric bypass (OAGB) which is now an established bariatric procedure, maybe another option for conversion of SG [15, 16]. Comparative studies, reviews and meta‐analyses looking at the role of RYGB and OAGB as conversional surgery after SG are rare, present limited numbers [17, 18] or investigated conversional surgery after different primary procedures than SG [19–21].…”
