Dielectric elastomers are active materials that undergo large deformations and change their instantaneous moduli when they actuated by electric fields. By virtue of these features, composites made soft dielectrics can filter waves across frequency bands electrostatically tunable . To date, to improve the performance adaptive phononic crystals , such as width at state, metaheuristics-based topol...

In this paper, a combination of algebraic and topological methods is applied to obtain new structural results on Gelfand residuated lattices. It demonstrated that Gelfand’s lattices strongly tied up with the hull–kernel topology. Particularly, it shown lattice if only its prime spectrum, equipped topology, normal. The class soft introduced, semisimple. are characterized using pure part filters....

Soft pneumatic bending actuators are commonly used in robotic grasping applications and can be applied for handling both delicate irregularlyshaped objects. Because these soft typically embedded with multiple air chambers inside soft, thin structures, their maximum payloads usually low compared to rigid designs of similar size. This article presents a actuator design using topology optimization...

The article deals with the correspondence between soft ideal topological spaces and ones. Investigation of is based on methods general topology, application results for omega open strongly sets given.

This paper presents the Zero-Voltage Switching (ZVS) performance of Dual Active Bridge (DAB) DC-DC converter for high power density aerospace applications. Switching transitions of the transistor occurring in favorable conditions such as device zero-voltage or zero-current is called as soft-switching. The benefits of soft-switching are reduced switching losses, switch stress, low electromagneti...

A new symmetrical topology switching power amplifier is introduced for professional audio use. The amplifier is composed by a pair of semi soft switched half-bridges with independent feedback control. Whole overall layout looks very similar than an already bridge configured stereo amplifier with few exceptions. Although the complexity of the proposed topology is at least twice of the convention...

ficient of Determination and Nash-Sutcliffo Coefficient were used for comparing the prediction ability of the developed models. Four input parameters were Body & texture, aroma & flavour, moisture, and free fatty acid. Neurons in two hidden layers varied from 1 to 20. One output parameter was sensory score. Experiments show that Elman model with combination of 4-17-17-1 performed significantly ...

The boost topology is the most popular topology used in power factor correction circuits. The efficiency and performance of the boost converter depends on the switching frequency affecting the switching losses. At high frequency operations the switching losses of the converter is considerable and decreases the efficiency of the converter. To remove this problem the converter is designed to oper...
