Abstract: This paper proposes a new control strategy for bidirectional DC-DC converter. This strategy aims at controlling a bidirectional DC-DC converter to behave like a virtual conductor. As a matter of fact, the voltage difference between the terminals of any conductor is zero volts. Conversely, the main target of this proposed control strategy is to keep the voltage difference between the c...

Low Temperature Co-fired Ceramic (LTCC) technology is being used for various high frequency applications such as T/R modules for radar, bluetooth communication modules, LAN switches, and automotive radar. One of the key properties of the electronic packages for these applications is microwave loss. LTCC metallizations are typical thick film conductors. Conventional thick film technology has rel...

Ionic skin (I-skin) is an emerging skin-inspired sensor that has received increasing interest for the next-generation wearable electronics. However, profound challenges I-skin remain in achieving multiple signal responses (e.g., strain, pressure, and humidity) self-healability to fully mimic human skin. Herein, a Fe3+ ion-coordinated poly(acrylic acid) ionogel (PAIFe) with high stretchability, ...

Audible noise generated from water drops collected on the transmission line conductor surface during foul weather is a major concern in UHV (ultrahigh voltage) transmission line design. Although the noise can be kept to an acceptable level by maintaining a surface electric gradient below 15 to 17 kV/cm, this alternative is quite costly since it would mean having larger conductor bundles and hen...

Mixed ionic/electronic conducting (MIEC) oxides, such as SrFeCo0.5Ox, (La0.6Sr0.4)(Co0.2Fe0.8)O3, and BaCeO3, are a class of ceramics that contain ionic and electronic carriers in high enough concentration that both forms of charge conduction are exhibited at high level, typically at temperatures in excess of 500°C. Because of their properties, the demand for MIEC oxide-based devices has grown ...

Proposition 4.1 (1) of this article is not correct as stated. For instance, if ε is the quadratic Dirichlet character of conductor 15, then there are two newforms in Sk(Γ1(15), ε) with coefficients in Q, and these are twists of each other by the quadratic character of conductor 3, whereas the quantity u in the proposition is 0 here. I am grateful to Steve Donnelly for pointing out this example....

We propose a general workflow to numerically estimate the spread of electrical excitation in the patients' hearts. To this end, a semi-automatic segmentation pipeline for extracting the volume conductor model of structurally normal hearts is presented. The cardiac electrical source imaging technique aims to provide information about the spread of electrical excitation in order to assist the car...

Meaningful interconnect design and compliance analysis must start with the identification of broadband dielectric and conductor roughness models. Such models are not available from manufacturers and the model identification is the most important element of successful interconnect design for link paths with 10-50 Gbps and higher data rates. Electromagnetic analysis of interconnects without such ...
