Abstract:

A 1-phase 4-pole starting capacitor induction motor which is used as an activator of the table drilling machine has a more complicated construction because it has a centrifugal switch which is connected in series with the capacitor for its initial start and a high rotational speed of the stator field, which is 1500 rpm. While a 3-phase 6-pole induction motor has a much simpler construction because it does not require a centrifugal switch and a capacitor for its initial start with a low rotational speed of the stator field, which is 1000 rpm. This study discusses the effect of modifying the sta

Abstract:

Pole-phase changing induction machines (IMs) offer the capability to extend the torque-speed envelope compared to their fixed pole-phase counterparts. Dynamic pole-changing can achieve higher torque levels at lower speeds, utilizing higher pole numbers, and extended flux-weakening range with lower pole-number operations. This paper investigates the design impact on the optimum pole-phase changing behavior and respective split of the operating region to different pole-phase operations. Additionally, the improvement in terms of the overall torque per ampere capability and efficiency is illustrat

Abstract:

This survey proposes a mitigation approach for common mode voltage produced in a three-level five-phase inverter fed two parallel-connected five-phase induction machines controlled by direct torque control. The switching frequencies used in the inverter fed these types of drives are characterized by a large amplitude of the produced common mode voltage waveforms (), leading to prominent issues, especially with the near introduction of wide-gap semiconductor technologies. In this context, the introduced approach is an extension to a multi-motor drive of the TATTE method, exploiting the concept

One of the important challenges of today is to ensure energy efficiency and improve the performance of the most common induction electric drives (IEDs) for production and lifting and handling machines. Increasing the overall control range and stable speed control in AEDs is often ensured by the use of pulse-key or phase-pulse control systems for the speed of rotation of the AD FR, in which the control is carried out in the rectified rotor current circuit. The presence in such schemes of a rotor winding voltage rectifier creates conditions for the use of the dynamic self-excitation braking (DSB

Three-phase induction motors (IMs) are electrical machines used on a large scale in industrial applications because they are versatile, robust and low maintenance devices. However, IMs are significantly affected when fed by unbalanced voltages. Prolonged operation under voltage unbalance (VU) conditions degrades performance and shortens machine life by producing imbalances in stator currents that abnormally raise winding temperature.

Abstract:

AbstractAmyloidogenic processing of the amyloid precursor protein (APP) forms the amyloid-β peptide (Aβ) component of pathognomonic extracellular plaques of AD. Additional early cortical changes in AD include neuroinflammation and elevated iron levels. Activation of the innate immune system in the brain is a neuroprotective response to infection; however, persistent neuroinflammation is linked to AD neuropathology by uncertain mechanisms. Non-parametric machine learning analysis on transcriptomic data from a large neuropathologically characterised patient cohort revealed the acute phase protei

Abstract:

AbstractPump fault diagnosis is essential for the maintenance and safety of the device as it is an important appliance used in various major sectors. Fault diagnosis at the proper time can reduce maintenance costs and save energy. This article uses a Simulink model based on mathematical equations to analyze the effects of parameter estimation of three-phase induction motor-based centrifugal pumps in inter-turn fault conditions. The inter-turn fault causes a massive in, a massive increase in current, which severely affects the parameters of both motor and pump. These have been analyzed by simul

Abstract:

AbstractRecently, renewable resources such as wind, hydro, and tidal have experienced a rapid development. Electricity production, based on wind, has been concentrated on a large scale. Additionally, a doubly fed induction generator has been used in wind farms on a large scale. This machine is influenced by the multiple transient states that are happening in the grid. Many researchers studied the effect of voltage-dip on DFIG performance; none of them studied the effect of voltage-dip sharing with wind-speed changing for both sub- and hyper-synchronous modes. In this paper, DFIG behavior is in

Abstract:

Abstract Research on Self –excited induction generator (SEIG) brings a lot of attentions in the last three decades as a promising solution in distributed generation systems with low cost investment. There are two important fixations to attend in the operation of SEIG based systems, a) excitation and b) voltage regulation. Many procedures are reported regarding selection of excitation capacitance in the literature, based on state-state analysis, dynamic modeling, empirical formulas and machine parameters which involve various levels of complexity in findings. Moreover, the voltage regulation is

Abstract:

ABSTRACT I argue that this examination and appreciation for the shift to abductive reasoning should be extended to the intersection of neuroscience and novel brain-computer interfaces too. This paper highlights the implications of applying abductive reasoning to personalized implantable neurotechnologies. Then, it explores whether abductive reasoning is sufficient to justify insurance coverage for devices absent widespread clinical trials, which are better applied to one-size-fits-all treatments.

Induced pluripotent stem (iPS) cells have first been generated from fibroblasts using retroviral insertion of OCT4A, SOX2, c-MYC and KLF4. Since then, a number of methods have been developed to avoid the random integration of ectopic factors in the genome and the low efficiency of the process. Those include alternative integrating, non-integrating, excisable and DNA-free systems, but they all present challenges that pre

Abstract:

Causal attributions are an element of a frame (Entman, 1991). Furthermore, a causal attribution organizes the anatomy of a problem within a text. Hereby, causal attributions provide explanations of problems in terms of their expectations, the underlying reasons or the causes that led to one or more problems depicted in the text.
