There is a requirement to find accurate parameters to accomplish precise dimensional accuracy, excellent surface integrity and maximum MRR. This work studies the influence of various cutting parameters on output parameters like Cutting force, Surface roughness, Flatness, and Material removal rate while face milling. A detailed finite element model was developed to simulate the face milling proc...

The relative permittivity of LCP material has been characterized within the whole 60 GHz frequency band using the microstrip ring resonator (MRR) method. Using a circuit model, the gap capacitance of the MRR has been taken into account in order to improve the accuracy of the determined relative permittivity. The results show that the relative permittivity of LCP is almost constant (εr ≈ 3.1) wi...

The paper envisages the study to optimize the effects of process variables on surface roughness, MRR and power consumption of En24 of work material using PVD coated tool. In the present investigation the influence of spindle speed, feed rate, and depth of cut were studied as process parameters. The experiments have been conducted using full factorial design in the design of experiments (DOE) on...

We report a high-responsive hot-electron photodetector based on the integration of an Au–MoS 2 junction with silicon nitride microring resonator (MRR) for detecting telecom-band light. The coupling evanescent field MRR Schottky region enhances injection efficiency. device exhibits high responsivity 154.6 mA W −1 at wavelength 1516 nm, and moderately uniform responsivities are obtained over rang...

Microstructured steel 40Cr13, which is considered a hard-to-machine due to its high mechanical strength and hardness, has wide applications in the dies industry. This study investigates influence of three process parameters 355 nm nanosecond pulse laser on ablation results based analysis variance (ANOVA) back propagation (BP) neural network. The ANOVA show that power greatest depth, width, mate...

The objective of this paper is to determine the optimal setting of the process parameters on the electro-discharge machining (EDM) machine while machining AISI H13 tool steel. The parameters considered are pulse current, pulse-on-time, pulse-off-time and gap voltage ; whereas the responses are Tool wear ratio (TWR) and material removal rate (MRR). The optimal setting of the parameters are deter...

Bioinformatic analysis of the putative nuclease domain of the single polypeptide restriction-modification enzyme LlaGI reveals amino acid motifs characteristic of the Escherichia coli methylated DNA-specific Mrr endonuclease. Using mutagenesis, we examined the role of the conserved residues in both DNA translocation and cleavage. Mutations in those residues predicted to play a role in DNA hydro...

While developing an approach towhy-QA, we extended a passage retrieval system that uses offthe-shelf retrieval technology with a re-ranking step incorporating structural information. We get significantly higher scores in terms of MRR@150 (from 0.25 to 0.34) and success@10. The 23% improvement that we reach in terms of MRR is comparable to the improvement reached on different QA tasks by other r...
