Background: Antenatal group discussions (AGDs) are utilized in antenatal peer support. Its application controlling fear of childbirth (FOC) has not been widely studied Africa. We examined the effect AGDs on FOC among pregnant women. Methods: This experiment was done between 2020 at a teaching hospital Nigeria. randomly assigned 218 consenting primigravid women into treatment (n = 111) and contr...

This paper focuses on Firm-Hosted Online Communities (FOC) communities that are hosted by organizations for commercial purposes. The purpose of this paper is twofold. Firstly, we will examine examples of existing FOCs in order to develop a broader view of how FOCs have been utilized in product business. This work results with a dimensional view illustrating some discovered opportunities with FO...

One of the most important development in control area for induction motor has been field oriented control (FOC) established firstly by (Blaschke, 1972). However, the performance of this technique is affected by the motor parameter variations and unknown external disturbances. To improve the dynamic response and reduce the complexity of FOC methods, an extension amount of work has been done to f...

Abstract Field‐oriented control (FOC) has been broadly used as an accurate method for electric drives. The traditional FOC approach effectively developed to 3‐phase induction motor (3φ IM) drive systems in recent decades. Despite the usefulness of methods during normal condition, these strategies are unable a wye‐connected 3φ IM y ) under stator winding open circuit fault (SWOCF). This paper di...

<p>The stability analysis is one of the most important elements to describe performance AC drive systems under both dynamic and steady-state operating circumstances. This particularly essential because electric motors operate over a wide range speeds utilize complex control such as field-oriented (FOC). study establishes small-signal (SSSA) in 1-horsepower vector-controlled Y-connected th...

We introduce the logic FOCN(P) which extends first-order logic by counting and by numerical predicates from a set P, and which can be viewed as a natural generalisation of various counting logics that have been studied in the literature. We obtain a locality result showing that every FOCN(P)-formula can be transformed into a formula in Hanf normal form that is equivalent on all finite structure...

The high-level penetration of renewable energy sources (RESs) is the main reason for shifting conventional centralized power system control paradigm into distributed control. This massive integration RESs faces two problems: complex controller structure and reduced inertia. Since frequency stability directly linked to system’s total inertia, integrated badly affected. Thus, a fractional order (...

The onion (Allium cepa L.) belongs to the family Alliaceae and has paramount importance among vegetable crops around globe. Salinity stress soil-borne fungus Fusarium oxysporum f. sp. Cepa (FOC), which is cause of basal rot, are potentially hazardous factors related yield crops. present study was conducted in CRD using three replicates vitro conditions a greenhouse investigate impact (salinity ...

Although, Single-Sided Linear Induction Motor (SLIM) utilization has increased in railway applications due to their numerous advantages in comparison to Rotational Induction Motors (RIM), there are some sophistication in their mathematical models and electrical drive. This paper focuses on the problems of SLIM modeling, with assuming end-effect on the basis of Field Oriented Control (FOC) as a ...
