The temperature determination using luminescent materials is nowadays considered the perspective remote technique for gauging, despite few examples reported so far combining wide operating range with satisfying relative thermal sensitivity and uncertainty values. In this paper, we study Y3(Al,Ga)5O12:0.1%Pr phosphors controlled Ga:Al composition to deliberately affect their properties. We demon...

A compact printed hybrid-mode antenna for dual-band dual-sense circular polarisation (CP) has been proposed. To achieve CP, a hybrid mode produced by an L-shaped element and loop is used. In the lower frequency band, left-handed CP radiated vertical electric field from horizontal element. higher right-handed Both elements produce resonances in bands. The operational principle clarified using si...

Repetitive nonreentrant ventriculoatrial synchrony during dual-chamber pacing is characterized by long intervals alternating with short intervals. This arrangement activated automatic mode switching in a St Jude dual-chamber pacemaker in which the algorithm requires an atrial sensed event for automatic mode switching initiation. Automatic mode switching activation by an atrial sensed event (ret...

Dual-mode surface-plasmon resonance (SPR) sensors use both long- and short- range surface plasmon waves to differentiate surface binding interactions from interfering bulk effects. We have optimized the design of these sensors for minimum surface limit of detection (LOD) using a Cramer-Rao lower bound for spectral shift estimation. Despite trade-offs between resonance width, minimum reflectivit...

Two designs of conical-beam array antennas are presented for different fifth-generation applications. They based on slotted cylindrical waveguides and a travelling-wave topology, where the waveguide is used to progressively excite cross-slot array. A total 384 cross-slots, formed by transversal longitudinal slots, grouped in rings eight equally-spaced cross-slots. The propagation TM <sub xmlns:...

Dual-mode fuzzy dynamic matrix control (fuzzy DMC-FDMC) algorithms with guaranteed nominal stability for constrained nonlinear plants are presented. The algorithms join the advantages of fuzzy Takagi-Sugeno modeling and the predictive dual-mode approach in a computationally efficient version. Thus, they can bring an improvement in control quality compared with predictive controllers based on li...

In this paper, the effect of the Intake Valve Deactivation (IVDA) on engine performance is investigated in detail. Based on an optimization platform with Genetic Algorithm (GA) and engine thermodynamic model, the characteristics of the engine volumetric efficiency and pumping loss were studied under the cam-drive, Single Intake Valve (SIV) and Dual Intake Valves (DIV) operating modes, and the e...
