In memoria di Francesco Orlando

Marco Di Francesco and Andrea Pascucci

where z = (x, t) ∈ RN×R and 1 ≤ p0 ≤ N. By convenience, hereafter the term “Kolmogorov equation” will be shortened to KE. We assume the following hypotheses: (H.1) the matrix A0 = (aij)i,j=1,...,p0 is symmetric and uniformly positive definite in R p0 : there exists a positive constant μ such that |η| μ ≤ p0 ∑ i,j=1 aij(z)ηiηj ≤ μ|η|, ∀η ∈ R0 , z ∈ R; (1.2) (H.2) the matrix B ≡ (bij) has constan...

Segunda parte: Sistemas de memoria de largo plazo: Memoria episódica, sistemas de memoria no declarativa y memoria de trabajo

According to recent evidence, memory can be conceptualized as a series of subsystems working together to reach the same final goal. In the present time, most authors coincide in proposing a main division or long-term memory systems in mammals. This division separates memory in two categories: declarative and not declarative, often conceptualized also as explicit and implicit memories, respectiv...

Apprendimento Dinamico Della Memoria Di Lavoro: Una Realizzazione in Elettronica Analogica

La classi cazione degli stimoli ambientali viene considerata uno dei misteri fondamentali del sistema cognitivo realizzato dal cervello ([1]), in grado di elaborare stimoli ambientali che si presentano ad esso in gran numero e possono cambiare rapidamente. Questi stimoli inoltre si presentano nel tempo in sequenze impredicibili, ed anche quando lo stesso stimolo appare pi u volte, non si presen...

Ontology : a consumer ’ s point of view Primo di essere ingenieri siete uomini ! Francesco de Sanctis

Ontology is the science of objects. It is an ancient discipline, which has recently been rediscovered, and overhauled, for the purposes of Artificial Intelligence. Ontology has been concerned with the properties of objects, with their modes of existence and with questions such as how they can be divided in parts and how they fill space. This presentation takes the position of a user of ontologi...
