Abstract-- Renewable drive technology is developing in the current era, one of which is electric transportation. The Switched Reluctance Motor (SRM) was chosen for the transportation development because it has many advan...

Along with technological advances in modern times, and the development of science, human needs are also growing. In order to facilitate human work, many technologies have been created using automatic systems. One of them...

ABSTRACT The limitations of traditional direct current–electrocoagulation (DC–EC) in wastewater treatment encompass electrode passivation, high energy consumption and substantial sludge generation. Alternating curren...

Scanned reactive-ion-beam etching method was proposed to transfer two-dimensional mask patterns into quartz substrate, which would produce a larger-size and polarization-independent two-dimensional grating. This method w...

Abstract We use the two dimensional finite element method (2D-FEM) in the frequency domain to characterize the transmission properties of 90°-bend periodic segmented waveguides (PSWs). We investigated the dependence of ...

The problem with DC motors is speed regulation, adjusted to the needs in the field. The speed of a DC motor can be changed by adjusting the motor voltage. To overcome this, the motor voltage is regulated using Pulse Wide...

Abstract It is difficult to effectively improve the low bonding strength of TA1/304 clad plates. This study proposes a new process for applying pulse current (1500 A, 500 Hz, 50% duty cycle) to TA1/304 clad plates duri...

Impaired wound healing is one of the Diabetes mellitus complications. Low-intensity Pulsed Ultrasound (LIPUS) therapy may accelerate the impaired wound healing. The use of LIPUS therapy in the early inflammatory phase ca...

Metamaterials are mostly designed in the time-harmonic scenario where wave propagation can be spatially manipulated. Tailoring the electromagnetic response of media in time has also gained the attention of the scientific...

Electrochemical migration (ECM) is a major concern in modern electronics because miniaturization has reduced insulation distances and electronics are now operated in harsher environments than before. Previous studies on ...

A new concept of electrochemically modulated single-molecule localization super-resolution imaging is developed. Applications of single-molecule localization super-resolution microscopy have been limited due to insuffici...

Exceptional points (EPs) in non-Hermitian systems have attracted significant interest due to their unique behaviors, including novel wave propagation and radiation. While EPs have been explored in various photonic system...

We present the intracavity generation of beams with radial polarization at an average output power of 750 W and an optical efficiency of 43% from a continuous wave thin-disk laser. Circular grating waveguide output coup...

Electrochemical cutting with internal electrolyte jetting is a high-efficiency and high-precision machining technology suitable for cutting workpieces with a thickness exceeding 1 mm. In this process, a metal tube with...

The first period-doubling bifurcation of a dc-dc buck converter controlled by a zero-average dynamic strategy is studied in detail. Owing to the saturation of the duty cycle, this bifurcation is followed by a border-coll...

Periodically poled thin-film lithium niobate (TFLN) crystals are the fundamental building block for highly-efficient quantum light sources and frequency converters. The efficiency of these devices is strongly dependent o...

A novel ionic material from thiophene and bromobutane was synthesized using ultrasound assistance as an alternative energy source. The optimal sonochemical reaction was carried out at 185 W, 20% duty cycle, 60 min in an ...

Gamma-Ray Bursts (GRBs) are one of the brightest transient events detected, with energies in their prompt phase ranging from keV to GeV. Theoretical models predict emissions at higher energies in the early times of the a...

Natural gas is a cleaner fuel for combustion and with less carbon intensity than traditional ones (gasoline and diesel); however, it requires an adequate calibration of the electronic management of the internal combustio...

This article presents an light-emitting diode (LED) driver that actively reduces low-frequency output current ripple through a duty-cycle modulation scheme, enabling the use of compact film capacitors and eliminating ele...

Abstract The current gait planning for legged robots is mostly based on human presets, which cannot match the flexible characteristics of natural mammals. This paper proposes a gait optimization framework for hexapod rob...

En este artículo pretendemos postular algunos argumentos sobre la presencia efectiva de Numa en la obra del ciclo de Región. La hipótesis de nuestro trabajo sostiene que Numa articula una serie de topoi, simbolizados ...

"The thermochemical decomposition of beech wood biomass results in a poor quality bio-oil, which cannot be directly used in diesel engines. In order to make this oil resemble liquid fossil fuels, an upgrading technique s...
