A room-temperature magnetic refrigerator, consisting of permanent magnet, active magnetic refrigeration (AMR) cycle bed, pumps, hydraulic circuit, active magnetic double regenerator cycle (AM2RC) and control subsystems, has been designed.
In the out-of-step process of a system, the electrical center, as the lowest voltage point [11], owns the periodic zero passage of circuit active power [12], maximum potential energy, overall infusion of the reactive power at both sides towards the center [13] and 0 ~ 360° periodical continuous changes of the bus voltage phase angle difference at both sides and other electrical quantity features.
The extended frequency range, lower propagation loss, and tunable properties by changing the metal-dielectric ratio might be useful for biosensor, integrated circuits, active SPP devices.
Expression of GHS-R1A in islet endothelial cells, together with the established production of ghrelin within pancreatic islets [ 3, 34], may sustain the autocrine/paracrine circuits active between endocrine and endothelial counterparts within the islet of Langerhans [ 14].
The combined analysis of target prediction and expression of 305 miRNAs with predicted targets and 12,748 target genes allowed us to reconstruct post-transcriptional regulatory networks describing the most probable regulatory interactions and circuits active in transitions characterizing tumor development and progression.
In a previous study, the authors have developed a high performance active passive alternative to the semi-active absorber that uses a combination of a passive electrical circuit and active control actions.
The first is the dynamic power that is generated when the circuit is active and denoted PDYN,BB in the following.
In addition, in the proposed circuit both active building blocks operate in negative feedback loop which results in an overall enhanced performance.
To reduce bending vibration, some authors have suggested the use of piezoelectric elements shunted by an external electric circuit or active damping via a piezo stack of actuators [5, 6].
By making a collection of almost all Wien bridge-based chaotic circuits, we have investigated these oscillators in terms of chaotic dynamics, circuit structures, active building blocks, nonlinear element structures and operating frequency by using PSpice simulations and laboratory experiments.
For M max =2, the three MINLP solvers, MITS, ACOmi and eSS, reached the same solution, the circuit with active pairs (P l a c1, t e t R) and (P t e t2, L a c I).
