TL;DR: In this article, a cost-effective power amplifier circuit is developed and interfaced with a LabVIEW program to characterize soft magnetic materials, and the measurements for a sinusoidal excitation from the proposed setup are validated with those from a standard commercial measuring setup.
Abstract: Energy losses during the magnetization process of soft magnetic laminations depend on the excitation waveform. Manufacturers of magnetic materials may not provide losses for different excitation waveforms. This may affect the accuracy of the predicted losses which are used to estimate the performance of electrical equipment during the predesign stage. Thus, a characterization tool which is capable of measuring hysteresis loops under controlled magnetization is required. Digital characterization systems available in literature use expensive commercial power amplifiers. In this work, a cost-effective power amplifier circuit is developed and interfaced with a LabVIEW program to characterize soft magnetic materials. The measurements for a sinusoidal excitation from the proposed setup are validated with those from a standard commercial measuring setup. The system is also used to measure hysteresis loops for arbitrary magnetization conditions (magnetic flux density ( $ {B}$ ) with harmonics). The proposed setup can operate over a frequency range 35–500 Hz. A small Epstein frame is also designed for measurements at higher frequencies (>200 and <500 Hz). A provision is also made to predict three components of dynamic hysteresis losses at any frequency in the above range using the loss separation approach. This capability of the setup enables the user to predict the losses at frequencies beyond the capability of the tool. The predicted losses using this algorithm are validated with measured losses. The proposed setup is cost-effective and can be developed easily using basic electronic components.

Abstract: This chapter discusses concepts and various research-oriented IAM techniques for growing connected healthcare system. Identity and access management (IAM) in a computer system includes a security framework, tools, and technologies to control access to critical information resources to legitimate users in the right context. IAM is even more challenging for healthcare organization as they are responsible for the protection of users identities and valuable medical records. Health care organizations are more prone to attacks than financial institutions. Data breaches in e-healthcare can lead to identifying theft, billing, and insurance frauds. To prevent such breaches IAM for health care must be even more secure and scalable to meet current challenges. IAM cannot be explained without learning the concept of identification.
