Compacted graphite iron (CGI) is considered as the potential replacement of flake graphite iron (FGI) for the manufacturing of new generation high power diesel engines. Use of CGI, that have higher strength and stiffness as compared to FGI, allows engine to perform at higher peak pressure with higher fuel efficiency and lower emission rate. However, not only for its potential, CGI is of an area...

This research outlines the Taguchi optimization methodology, which is applied to optimize cutting parameters in drilling of glass fiber reinforced composite (GFRC) material. Analysis of variance (ANOVA) is used to study the effect of process parameters on machining process. This procedure eliminates the need for repeated experiments, time and conserves the material by the conventional procedure...

Conducting studies that assist in the evaluation of agroecosystems is essential for advancing biodiverse and sustainable agriculture. This study aimed to assess impact intercropping on photosynthetic activity Arabica coffee plants. The experiment was conducted municipality Alegre, Espírito Santo, southeastern Brazil. Three cropping systems were studied: monoculture; intercropped with Nanicon va...

Machining-induced white layers and severely deformed are undesirable surface integrity features which can be formed when machining high-strength aerospace alloys. An orthogonal milling process has been designed performed to assess the impact of cutting speeds, tool wear, edge radius climb vs conventional on layer formation plastic strain distribution. The deformation in machined associated with...

in this paper some new applications of empirical mode decomposition (emd) and hilbert spectrum in seismic ground-roll attenuation, random noise attenuation and spectral decomposition are introduced. hilbert spectrum is a time-frequency representation for hilbert-huang transform which is obtained by combination of instantaneous frequency (if) concept and intrinsic mode function of empirical mode...

BACKGROUND Skin incisions have traditionally been made using a scalpel. Cutting diathermy, a more recent alternative, is thought to increase the risk of infection, impair healing and decrease cosmesis. Recent studies suggest otherwise, claiming that diathermy may offer potential advantages with respect to blood loss, incision time and postoperative pain. The aim of this meta-analysis was to com...
