In low-cost permanent magnet synchronous motor (PMSM) drive systems, the rotor position is usually estimated based on the back-electromotive force. However, such estimation methods have the common drawback of having large errors in low-speed regions. In order to solve that drawback in the startup phase, the I-f startup method is studied as its compatibility with the FOC control structure. The purpose of such a method is to make the motor accelerate and overcome the low-speed threshold.

Several studies have proved that Polygenic Risk Score (PRS) is a potential candidate for realizing precision screening. The effectiveness of low-dose computed tomography (LDCT) screening for lung cancer has been proved to reduce lung cancer specific and overall mortality, but the cost-effectiveness of diverse screening strategies remained unclear.

Disparities in rates of contraceptive use are frequently attributed to unequal access to and affordability of care. There is a need to better understand whether common definitions of affordability that solely relate to cost or to insurance status capture the reality of individuals’ lived experiences.

The small business savings plan is designed to create awareness of all the cutting-edge tactics at readers' disposal and offer adivce about how to put these strategies into practice. Surprisingly, the vast majority of smaller companies don't recognize how they can reduce costs. Certainly they monitor expenses, reduce payroll in tough times, shop for low-priced vendors, and take other standard actions, but they fail to capitalize on the myriad of tools at their disposal.

Antibacterial packaging represents an active packaging solution crafted to uphold the quality and safety of products. One of the popular polymer used in food packaging is Linear Low-Density Polyethylene (LLDPE), due to its low cost, ease of processing, and high mechanical properties. Polymer blend based on LLDPE and antibacterial agent PHMG were prepared in the presence of PE-g_AM compatibilizer and DCP initiator.

This paper deals with a novel structure of serpentine micromixer with its high mixing efficiency and its fabrication of soft photolithography molds using dry film photoresist as an alternative to the conventional liquid photoresist, such as SU-8. This method provides simplification, significant time-savings, low cost due to non-cleanroom setting and less toxic developer solution.

The kinetic study was also carried out by studying the adsorption process at different temperatures using these two adsorbents to find the rate of adsorption process, its mechanism and to determine different thermodynamic parameters. For this purpose, different kinetic models were used which include film diffusion, particle diffusion, intraparticle diffusion, Elovich, Lagergren pseudo first order, Lagergren pseudo second order, simple first order and second order equations.

Especially, active metals require the modification maximum to escape the natural corrosion or passivation. The retention of sound performance of the metals as well as extension of their lifetime can be achieved by surface modification of coating formation. Chemical coating is one of the simple and low-cost methods of coating with great versatility including pre-treatment and post-treatment. This paper includes the most widely used inorganic and organic chemical coating methods and their fewer details and their future outlooks.

The article examines how firm leverage affects firm performance in the context of high and low agency costs. It explores the agency theory’s proposition that loans can mitigate the agency problem between shareholders and managers while potentially exacerbating the problem between shareholders and lenders. The study employed a mixed-methods approach, combining qualitative and quantitative methods. Secondary data from financial reports in Finn Pro and other sources was collected.
