In this paper we use a non cooperative equilibrium selection approach as a notion of stability in link formation games. Specifically, we follow the global games approach first introduced by Carlsson and van Damme (1993), to study the robustness of the set of Nash equilibria for a class of link formation games in strategic form with supermodular payoff(More)
This paper describes a new method based on a voltammetric electronic tongue (ET) for the recognition of distinctive features in coffee samples. An ET was directly applied to different samples from the main Mexican coffee regions without any pretreatment before the analysis. The resulting electrochemical information was modeled with two different(More)
An approach to an inhibition bioelectronic tongue is presented. The work is focused on development of an automated flow system to carry out experimental assays, a custom potentiostat to measure the response from an enzymatic biosensor, and an inhibition protocol which allows on-line detections. A Multi-commuted Flow Analysis system (MCFA) was selected and(More)
Let (X, L, V) be a triplet where X is an irreducible smooth complex projective variety, L is an ample and spanned line bundle on X and V ⊆ H 0 (X, L) spans L. The discriminant locus D(X, V) ⊂ |V | is the algebraic subset of singular elements of |V |. We study the components of D(X, V) in connection with the jumping sets of (X, V), generalizing the classical(More)
— In this paper, different classifiers were trained to identify myoelectric registers, in order to recognize nine different motions related to four degrees of freedom of the forearm. Three main methods were compared, namely Linear Discriminant Analysis, Artificial Neural Networks and Support Vector Machines. The behavior of pattern recognition schemes was(More)
We classify complex projective varieties of dimension 2r ≥ 8 swept out by a family of codimension two grassmannians of lines G(1, r). They are either fibrations onto normal surfaces such that the general fibers are isomorphic to G(1, r) or the grassmannian G(1, r + 1). The cases r = 2 and r = 3 are also considered in the more general context of varieties(More)
Network formation is frequently modeled using link-formation games under complete information presenting a multiplicity of Nash equilibria. Cooperative re…nements – such as strong, coalition proof or pairwise strong Nash equilibria-have been the standard tools used for equilibrium selection in these games. Alternatively, a non-cooperative re…nement derived(More)
This manuscript describes the use of a portable and low cost fluorescence setup to quantify the concentration of ochratoxin A (OTA) in beverage samples using an in-house developed system and different color models. It is reported that OTA is naturally fluorescent, for that reason an ultraviolet light at 365 nm was used to excite the samples and a(More)
