Abstract:

An improved mathematical model was used to extend polarization curves for direct propane fuel cells (DPFCs) to larger current densities than could be obtained with any of the previous models. DPFC performance was then evaluated using eleven different variables. The variables related to transport phenomena had little effect on DPFC polarization curves. The variables that had the greatest influence on DPFC polarization curves were all related to reaction rate phenomena. Reaction rate phenomena were dominant over the entire DPFC polarization curve up to 100 mA/cm2, which is a value that approache

This paper focuses mainly on the state modelling controlling of a new FACTS device named Distributed Power Flow Controller (DPFC). The paper also discusses the role and function of DPFC in power ﬂow controlling together with its economic evaluation. DPFC is one of the Distributed FACTS (D-FACTS) devices. Its function is similar to that of UPFC but instead of one series converters, several low power series converters are used in DPFC. Therefore, DPFC includes multiple series converters and one shunt converter without common dc link. This eventually enables the DPFC to fully control all power sy

Abstract:

<em>This paper presents a coordinated control strategy for a hybrid DC AC microgrid integrating photovoltaic PV wind turbine driven permanent magnet synchronous generator PMSG and a battery energy storage system BESS focusing on improving power quality and system reliability using a Distributed Power Flow Controller DPFC. The system connects solar wind battery AC and DC loads including a PMSM based water pump to a common DC bus. AC linear and non-linear loads are connected between the DPFC and the DC microgrids to balance loads enable bidirectional power flow and ensure reliable supply to AC l

Abstract:

AbstractThe aim of this study was to measure the satisfaction of patients treated in a dental hospital using a validated questionnaire on patient-dentist communication and investigate factors associated with satisfaction. Patients in the dental clinic answered 2 questionnaires: Dental Patient Feedback on Consultation (DPFC) and another regarding their oral health perceptions using a visual analog scale (VAS) and sociodemographic backgrounds. The correlation between patient’s satisfaction and other numerical variables was determined using Spearman's test. The Kruskal-Wallis and Mann-Whitney tes

Abstract:

1. We used single-pulse transcranial magnetic stimulation (TMS) to explore the temporal organization of the cortical control of memory-guided saccades in eight humans. The posterior parietal cortex (PPC) or the dorsolateral prefrontal cortex (DPFC), which are both known to be involved in the control of such saccades, were stimulated on the right side at different time intervals after the presentation of a flashed lateral visual target. The memorization delay was 2,000 ms. Single pulses were applied at 160, 260, and 360 ms after the flashed target, during the period of 700 and 1,500 ms, and fin

Abstract Aiming at the defects of DC energy storage elements, complex structure and large volume of unified power flow controller (UPFC), the paper combines flying capacitor multilevel technology and voltage vector synthesis technology with unified direct power flow controller. A three-level direct power flow controller (3L-DPFC) and a new control strategy are proposed. By obtaining the power parameters of the receiving end and substituting them into the derived calculation formula, the compensation voltage can be deduced to adjust the phase and amplitude, and the change relationship between t

In this paper, the series converters of Distributed Power Flow Controller are the main object of study. Its mechanism of suppressing power system oscillations is studied by theoretical analysis and formula derivation, which relies on a single-machine infinite-bus power system, installed the series converters. Then based on the mechanism, adopting the classic PI control and the damping controller, designed the transient stability control loop for the series converters. Finally, simulations performed by PSCAD/EMTDC, the results show that DPFC device can effectively suppress oscillation and impro

Abstract:

A rigorous mathematical model for direct propane fuel cells (DPFCs) was developed. Compared to previous models, it provides better values for the current density and the propane concentration at the exit from the anode. This is the first DPFC model to correctly account for proton transport based on the combination of the chemical potential gradient and the electrical potential gradient. The force per unit charge from the chemical potential gradient (concentration gradient) that pushes protons from the anode to the cathode is greater than that from the electrical potential gradient that pushes

Abstract:

Small vessel strokes (SVS) and intracerebral haemorrhages (ICH) are acute outcomes of cerebral small vessel disease (SVD). Genetic studies combining both phenotypes have identified three loci associated with both traits. However, the genetic cis-regulation at the protein level associated with SVD has not been studied before. We performed a proteome-wide association study (PWAS) using FUSION to integrate a genome-wide association study (GWAS) and brain proteomic data to discover the common mechanisms regulating both SVS and ICH.

Abstract INTRODUCTION Minimally invasive neuromodulation such as spinal cord stimulation (SCS) and occipital nerve stimulation (ONS) have shown to be successful for treatment of different types of pain such as chronic back or leg pain, complex regional pain syndrome (CRPS), and fibromyalgia. Recently, novel stimulation paradigm called burst stimulation was developed that suppresses pain to better extent than classical tonic stimulation. From clinical point of view, burst stimulation is very promising; however, little is known about its underlying mechanism. Hence, in this work we investigate m
