— This paper applies fractional order P ID k controller to torsional system's backlash vibration suppression control, in which the order k of D controller can not only be integer but also be any real number. In order to improve control system's robustness against backlash non-linearity, several methods have been proposed. However their design processes are(More)
—In this paper, low-order integral–proportional (IP), modified IP (m-IP), and modified integral–proportional– derivative (m-IPD) controllers are designed for the speed control of a two-mass system based on a normalized model and polynomial method. In order to have sufficient damping, the parameters of the controllers are determined through(More)
—Wireless power transfer (WPT) has attracted an ever increasing interest from both industry and academics over the past few years. Its applications vary from small power devices such as mobile phones and tablets to high power electric vehicles, and from small transfer distance of centimeters to large distance of tens of centimeters. In order to achieve a(More)
MicroRNAs (miRNAs) are important regulators of many physiological and pathological processes, including cell proliferation, apoptosis, and cell cycle arrest. In this study, we aimed to investigate the biological role of miR-155 in cervical cancer and the underlying molecular mechanism involved in tumorigenesis. The expression of miR-155 in human cervical(More)
Estimation of state of charge (SOC) is of great importance for lithium-ion (Li-ion) batteries used in electric vehicles. This paper presents a state of charge estimation method using nonlinear predictive filter (NPF) and evaluates the proposed method on the lithium-ion batteries with different chemistries. Contrary to most conventional filters which usually(More)
—This paper discusses a utility function-based control of a battery-ultracapacitor hybrid energy system. The example system employs the battery semi-active topology. In order to represent different performance and requirements of the battery and ultracapacitor packs, the two packs are modeled as two independent but related agents using the NetLogo(More)
Methylenetetrahydrofolate reductase (MTHFR) enzyme plays an important role in folate metabolism and MTHFR polymorphisms have been suggested to be associated with risk of various cancers. MTHFR C677T polymorphism is a common genetic alteration and may affect the host susceptibility to ovarian cancer. The aim of this study was to investigate the association(More)
To investigate the role of total cellular microRNA (miRNA) in regulating epithelial-to-mesenchymal transition (EMT) during human endometrial endometrioid adenocarcinoma (EEC). A miRCURY LNA microRNA array was used to evaluate the miRNA profiles of human EEC tissues and corresponding nontumorous endometriums. An in vitro model of TGF-β induced EMT in HEC-1-A(More)
