Performance criteria namely Material Removal Rate (MRR), Surface Roughness (SR) and Radial Over Cut (ROC) in electrochemical machining process greatly affected by the machining parameters like electrical parameters, electrode parameters, electrolyte parameters and workpiece properties. In the present work applied voltage (electrical parameter), tool feed rate (electrode parameter), electrolyte ...

The Micro Rain Radar 2 (MRR) is a compact Frequency Modulated Continuous Wave (FMCW) system that operates at 24 GHz. The MRR is a low-cost, portable radar system that requires minimum supervision in the field. As such, the MRR is a frequently used radar system for conducting precipitation research. Current MRR drawbacks are the lack of a sophisticated post-processing algorithm to improve its se...

We propose and experimentally demonstrate a continuously tunable fractional Hilbert transformer (FHT) based on a high-contrast germanium-doped silica-on-silicon (SOS) microring resonator (MRR). The propagation loss of a high-contrast germanium-doped SOS waveguide can be very small (0.02 dB/cm) while the lossless bend radius can be less than 1 mm. These characteristics lead to the fabrication of...

OBJECTIVE To assess the influence of diaphragmatic activation control (diaphC) on Sniff Nasal-Inspiratory Pressure (SNIP) and Maximum Relaxation Rate of inspiratory muscles (MRR) in healthy subjects. METHOD Twenty subjects (9 male; age: 23 (SD=2.9) years; BMI: 23.8 (SD=3) kg/m²; FEV1/FVC: 0.9 (SD=0.1)] performed 5 sniff maneuvers in two different moments: with or without instruction on diaphC...

Measurements of rain were obtained with a vertically pointing micro radar (MRR) with 1 min time resolution and 50(100) m height resolution at the German Baltic coast on the Zingst peninsula (54.43°N, 12.67°E). The comparison with a conventional rain gauge (30 min integration time) for a fi ve months summer period show a correlation coeffi cient of r = 0.87 for the rainrate and agreement within ...

Despite significant advancements over the years, there remains an urgent need for low cost diagnostic approaches that allow for rapid, reliable and sensitive detection of malaria parasites in clinical samples. Our previous work has shown that magnetic resonance relaxometry (MRR) is a potentially highly sensitive tool for malaria diagnosis. A key challenge for making MRR based malaria diagnostic...

BACKGROUND AND PURPOSE Several investigations have detected evidence of apoptosis in delayed neuronal death, but controversy prevails regarding this point. Recent studies have implicated mitochondria in apoptotic events. To explore relationships between delayed neuronal death and dysfunction of the respiratory chain, we analyzed mitochondrial redox changes in the gerbil hippocampus. METHODS W...

Optical low-coherence interferometry (OLCI) takes advantage of the variation in refractive index in silicon-wire microring resonator (MRR) effective lengths to perform glucose biosensing using MRR interferograms. The MRR quality factor (Q), proportional to the effective length, could be improved using the silicon-wire propagation loss and coupling ratio from the MRR coupler. Our study showed th...

WEDM is a one of the non-conventional machining processes used for machining complex shape components and hard materials to produce intricate shapes on the wide variety of materials. With the increasing demands of high surface finish and high rate of MRR of complex shape geometries, WEDM machining process is now being replaced by non-traditional machining processes. According to this paper, opt...

The experimental work of this study leads with electro discharge machining (EDM). A system for machining in this process has been developed. Many parameters are studied such as current, dielectric fluid, thickness of the workpiece. The main aim of this work is to calculate the metal removal rate (MRR), electrode wear (EW) using copper electrode when machining stainless steel 304 specimens of th...
