An ANN approach on the optimization of the cutting parameters during CNC plasma-arc cutting

Kechagias, J.; Pappas, M.; Karagiannis, S.; Petropoulos, G.; Iakovakis, V.; Maropoulos, S. (2010)

The objective of the present study is to develop an Artificial Neural Network (ANN) in order to predict the bevel angle (response variable) during CNC plasma-arc cutting of St37 mild steel plates. The four (4) input ...

Lattice kinetic schemes in toroidal geometry

Breyiannis, G.; Valougeorgis, D. (2006)

Lattice kinetic schemes has been consistently developed for the last 15 years as a tool to tackle complicated problems from a mesoscopic perspective. The system is described by a velocity distribution function, which follows ...

Spatial and temporal distribution of p,p′-DDE (1‑dichloro‑2,2‑bis (p‑chlorophenyl) ethylene) blood levels across the globe. A systematic review and meta-analysis

Koureas M., Rousou X., Haftiki H., Mouchtouri V.A., Rachiotis G., Rakitski V., Tsakalof A., Hadjichristodoulou C. (2019)

Background: Although p,p′‑DDT (1,1,1‑trichloro-2,2‑bis (p‑chlorophenyl)‑ethane) has been banned for decades in most countries, its major metabolite p,p′-DDE (1‑dichloro‑2,2‑bis (p‑chlorophenyl) ethylene) is still detected ...

Tribological coatings for aerospace applications and the case of WC-Co plasma spray coatings

Koutsomichalis, A.; Vaxevanidis, N.; Petropoulos, G.; Xatzaki, E.; Mourlas, A.; Antoniou, S. (2009)

Friction and wear requirements in aerospace systems are dictated by life limiting problems. One challenge is the broad range of contact stresses and sliding speeds for various movable devices. Another challenge is the ...
