Development of laser-based techniques for in situ characterization of the first wall in ITER and future fusion devices
Analysis and understanding of wall erosion, material transport and fuel retention are among the most important tasks for ITER and future devices, since these questions determine largely the lifetimeExpand

Algorithms to compute the topology of orientable real algebraic surfaces
TLDR
We present constructive algorithms to determine the topological type of a non-singular orientable real algebraic projective surface S in the real projective space, starting from a polynomial equation with rational coefficients for S. Expand

Degree reduction under specialization
We examine the degree relationship between the elements of an ideal I ⊆ R[x] and the elements of ’(I ) where ’ : R → R is a ring homomorphism. When R is a multivariate polynomial ring over a 3eld, weExpand

Computing the topology of real algebraic surfaces
TLDR
We present constructive algorithms to determine the topological type of a non-singular real algebraic projective surface S in the real projective space when there exists a line in RP3 not intersecting the surface. Expand

Real algebraic varieties with prescribed tangent cones
The definition of the tangent cone C(V, p) to an algebraic variety V at a point p was given by Whitney more than 40 years ago as one of the tools to get information about the geometric shape of aExpand

Local approximation of semialgebraic sets
Let A be a closed semialgebraic subset of Euclidean space of codimension at least one, and containing the origin O as a non-isolated point. We prove that, for every real s ≥ 1, there exists anExpand

Algorithmical determination of the topology of a real algebraic surface
TLDR
We present an algorithm to compute the topology of a non-singular real algebraic surface S in RP^3, that is the number of its connected components and a topological model for each of them. Expand

Chemical activation in view of MSWI bottom ash recycling in cement-based systems.
In the present study, the feasibility of recycling incinerator bottom ash in cementitious systems by means of chemical activation was investigated. Different Na-, K- and Ca-based hydroxides and saltsExpand

W/Cu composites produced by pulse plasma sintering technique (PPS)
Abstract W–Cu composites of various compositions were produced using the pulse plasma sintering (PPS) technique which applies pulsed high electric discharges to heat the powders subjected toExpand
