Modelling and H∞ Robust Control of a Neonatal Incubator
Abstract: This study presents the modelling of a neonatal incubator and the design of a robust H∞ controller. Neonates, who are born premature, often don’t have enough maturity to regulate their temperature. These infants have low metabolic heat production rate and may have high heat loss from the skin so they have an increased risk of death in the first week of their life. The core temperature of the human body …

Electromagnetic Fields (EMFs) and Cellular Phones: Controversy over Oral Carcinoma
Abstract: All electrical and electronic devices, anywhere where electricity (electrons) flows through wire, set up magnetic fields (EMFs=low frequency electromagnetic fields). Generation of EMFs occurs when there is any significant flow of electricity. EMFs are alternating fields that center on frequencies up to 300 Hz (radiation in the microwave range). The risk from EMFs occurs from significant exposure from high-voltage power lines or in substation transformers, microwave ovens, cellular phones, appliances …

FPGA-based Multichannel Digital Duty-Cycle Modulation and Application to Simultaneous Generation of Analog Signals
Abstract: The DCM (duty-cycle modulation) is used in industrial electronics as a special technique for producing switching time-varying periodic waves, with variable pulse width and modulation period. As an implication, unlike the fixed period of a PWM wave, the cyclic ratio of a DCM signal changes as a function of the modulating input according to a known function. However, most existing research works related to DCM-based instrumentation systems, are limited to …

A Suboptimal Nonlinear Duty-cycle Modulation Scheme
Abstract: The DCM (duty-cycle modulation) technique is increasingly used in industrial electronics applications, including instrumentation systems, interfacing drivers and signal transmission chains. However, in existing research works related to new applications of DCM technique, the linear approximation policy is used for the sake of structural simplicity and low implementation cost, at the expends of rigorous analysis and low approximation errors. In this paper, a suboptimal nonlinear DCM scheme is developed. It …
