Научная квалификационная работа посещена исследованию пульсаций электромагнитного момента в магнитоэлектрическом двигателе рулевой колонки автотранспортного средства. В первой главе выполнен обзор исследований на тему магнитоэлектрических машин с различной компоновкой магнитов на роторе и осуществлена постановка задачи научной квалификационной работы. Во второй главе рассмотрены вопросы имитационного моделирования магнитоэлектрической машины в конечно-элементной компьютерной среде. Выполнено планирование эксперимента, получена взаимосвязь между количеством пазов ротора, зубцами статора, коэрцитивной силы магнитов с позиции значений электромагнитного момента. В третьей главе выполнен расчет связанной модели магнитоэлектрический двигатель-инвертор напряжения-система управления.Scientific qualification work is visited to a research of pulsations of the electromagnetic torque in the magnetoelectric motor of a steering column of the vehicle. In chapter 1 the review of researches on magnetoelectric machine with various configuration of magnets on a rotor is executed and problem definition of scientific qualification work is carried out. In chapter 2 questions of a simulation modeling of the magnetoelectric machine in the terminating and element computer environment are considered. Scheduling of an experiment is executed, the interrelation between quantity of poles of a rotor, tooths of a stator, a coercive force of magnets from a position of values of the electromagnetic torque is received. In a chapter 3 calculation of the bound model the magnetoelectric motor

Clinical implications in laboratory parameter values in acute Kawasaki disease for early diagnosis and proper treatment

PurposeThis study aimed to analyse laboratory values according to fever duration, and evaluate the relationship across these values during the acute phase of Kawasaki disease (KD) to aid in the early diagnosis for early-presenting KD and incomplete KD patients.MethodsClinical and laboratory data of patients with KD (n=615) were evaluated according to duration of fever at presentation, and were compared between patients with and without coronary artery lesions (CALs). For evaluation of the relationships across laboratory indices, patients with a fever duration of 5 days or 6 days were used (n=204).ResultsThe mean fever duration was 6.6±2.3 days, and the proportions of patients with CALs was 19.3% (n=114). C-reactive proteins (CRPs) and neutrophil differential values were highest and hemoglobin, albumin, and lymphocyte differential values were lowest in the 6-day group. Patients with CALs had longer total fever duration, higher CRP and neutrophil differential values and lower hemoglobin and albumin values compared to patients without CALs. CRP, albumin, neutrophil differential, and hemoglobin values at the peak inflammation stage of KD showed positive or negative correlations each other.ConclusionThe severity of systemic inflammation in KD was reflected in the laboratory values including CRP, neutrophil differential, albumin, and hemoglobin. Observing changes in these laboratory parameters by repeated examinations prior to the peak of inflammation in acute KD may aid in diagnosis of early-presenting KD patients
