Inversio-ongelmat – Matematiikkaa Ja Sen Sovelluksia
Inversio-ongelmien teoria on matematiikan ja sen sovellusten kirjossa edelleen varsin nuori tutkimusala. Yksittäisiä ongelmia on toki tutkittu kauan, ja ensimmäinen yhtenäinen osakokonaisuus lienee 1950-luvulla kehitetty Gel’fandin koulukunnan yksiulotteinen käänteinen sirontateoria. Muutaman vuosikymmenen hiljaiselon jälkeen myös moniulotteisissa inversio-ongelmissa saavutettiin läpimurtoja, j...

We analyze M-theory compactified on (K3 × S)/Z2 where the Z2 changes the sign of the three form gauge field, acts on S as a parity transformation and on K3 as an involution with eight fixed points preserving SU(2) holonomy. At a generic point in the moduli space the resulting theory has as its low energy limit N = 1 supergravity theory in six dimensions with eight vector, nine tensor and twenty...

We study equational axiomatizations of bisimulation equivalence for the language obtained by extending Milner's basic CCS with string iteration. String iteration is a variation on the original binary version of the Kleene star operation p q obtained by restricting the rst argument to be a non-empty sequence of atomic actions. We show that, for every positive integer k, bisimulation equivalence ...
متن کاملOn Sen and Aristotle
In this paper I maintain that Amartya Sen’s Capability Approach (CA) implies a recuperation of practical science in Economics. Sen’s proposal has some problems closely related to this practical character: the heterogeneity and incommensurability of capabilities, its ambiguity concerning the use of the term “capability”, and the consequent lack of operative character of the CA. Sen recognizes th...

The use of computational steering for smog prediction is described. This application is representative for many underlying issues found in steering high performance applications: high computing times, large data sets, and many diierent input parameters. After a short description of the smog prediction model, its visualization and steering are described. The amount of computation needed to solve...
