Self-etch adhesives that etch, prime, and bond simultaneously should not exhibit incomplete resin infiltration within hybrid layers. We hypothesized that nanoleakage patterns in these systems are artifacts caused by mineral dissolution in mildly acidic silver nitrate. Resin-dentin interfaces bonded with four single-step, self-etch adhesives were examined for nanoleakage by conventional (pH 4.2)...

The novelty of this paper is a hybrid approach for modeling and implementing a real-time control strategy of a dc Servomotor angular speed by using a sliding mode control module. The sliding mode controller is embedded in an open-loop control system structure with a dc Buck converter to stabilize and regulate the converter output voltage, despite the load current changes and unregulated power s...

This work is concerned with multiple faults isolation for hybrid systems based on Global Analytical Redundancy Relationships (GARRs) approach. GARRs are derived from the Hybrid Bond Graph (HBG) model of a hybrid system with a specified causality assignment procedure. In this article, multiple faults are considered in a complex hybrid system and these faults can develop during a mode when the fa...

New hybrid materials made of gold nanoparticles functionalized by mesogenic ligands form laminated smectic phases. Mechanical shearing produces macro size domains with uniformly oriented layers with the layer normal either perpendicular (perpendicular mode) or parallel (transverse mode) to the shearing direction. This is in contrast to low weight and polymer liquid crystals which usually show p...

Plug-in hybrid electric vehicles (PHEVs) have a larger battery and can replace a certain amount of conventional fossil fuels with grid electricity, which differs from the traditional hybrid electric vehicles (HEVs). The application of the onboard electrical energy significantly influences the energy utilization efficiency and thus impacts the fuel economy. In this paper, the basic PHEV operatio...

Conventional electromagnetic transient (EMT) and phasor-domain hybrid simulation approaches presently exist for trans-mission system level studies. Their simulation efficiency is generally constrained by the EMT simulation. With an increasing number of distributed energy resources and non-conventional loads being installed in distribution systems, it is imperative to extend the hybrid simulatio...
