Comparative analysis of brushless DC and switched reluctance motors for optimizing off-grid water pumping.

Sci Rep

January 2025

Department of Theoretical Electrical Engineering and Diagnostics of Electrical Equipment, Institute of Electrodynamics, National Academy of Sciences of Ukraine, Beresteyskiy, 56, Kyiv-57, Kyiv, 03680, Ukraine.

Off-grid water pumping systems (OGWPS) have become an increasingly popular area of research in the search for sustainable energy solutions. This paper presents a finite element method (FEM)-based design and analysis of Brushless-DC (BLDC) and Switched Reluctance Motors (SRM) designed for low-power water pumping applications. Utilizing adaptive finite element analysis (FEA), both motors were designed with identical ratings and design parameters to ensure a fair comparison.

Today, with the increasing use of the Internet of Things (IoT) in the world, various workflows that need to be stored and processed on the computing platforms. But this issue, causes an increase in costs for computing resources providers, and as a result, system Energy Consumption (EC) is also reduced. Therefore, this paper examines the workflow scheduling problem of IoT devices in the fog-cloud environment, where reducing the EC of the computing system and reducing the MakeSpan Time (MST) of workflows as main objectives, under the constraints of priority, deadline and reliability.

Background: Doxorubicin (DOX) is a potent chemotherapeutic agent for breast cancer, but its effectiveness is often diminished by resistance mechanisms, particularly through p-glycoprotein (P-gp) mediated drug efflux. Clarithromycin (CAM), a macrolide antibiotic, inhibits multiple metabolic pathways including CYP3A and P-gp, potentially countering DOX resistance.

Objective: This study aimed to evaluate the potentiation of DOX and its effectiveness against the MCF-7 breast cancer cell line by encapsulating both DOX and CAM in PEGylated liposomes.

This study first proposes an innovative method for optimizing the maximum power extraction from photovoltaic (PV) systems during dynamic and static environmental conditions (DSEC) by applying the horse herd optimization algorithm (HHOA). The HHOA is a bio-inspired technique that mimics the motion cycles of an entire herd of horses. Next, the linear active disturbance rejection control (LADRC) was applied to monitor the HHOA's reference voltage output.

Introduction: In NCCN favorable intermediate-risk (FIR) prostate cancer (PCa) patients treated with radical prostatectomy (RP), we tested the effect of upstaging and upgrading on cancer-specific mortality (CSM).

Methods: Within the SEER database (2010-2021), upstaging (≥pT3a or pN1) and upgrading (ISUP ≥3) rates in FIR RP patients were tabulated. Kaplan-Meier (KM) plots and multivariable Cox-regression models (CRMs) were fitted.

Purpose Of Review: Transurethral resection of bladder tumor (TURBT) remains the basis of bladder tumor diagnosis and an effective means of treating nonmuscle invasive bladder cancer (NMIBC). There are several limitations to this procedure: TURBT may cause free floating of malignant cells in the bladder and as a result re-implantation and early recurrence. Also, it does not allow the pathologist to define the correct spatial orientation of the specimen.
