Creating agent platforms to host agent-mediated services that share resources
After a period where the Internet was exclusively filled with content,
the present
efforts are moving towards services, which handle the raw information to
create
value from it. Therefore labors to create a wide collection of
agent-based services
are being perfomed in several projects, such as Agentcities does.
In this work we present an architecture for agent platforms named
a-Buildings. The
aim of the proposed architecture is to ease the creation, installation,
search and
management of agent-mediated services and the share of resources among
services.
To do so the a-Buildings architecture creates a new level of abstraction
on top of
the standard FIPA agent platform specification.
Basically, an a-Building is a service-oriented platform which offers a
set of
low level services to the agents it hosts. We define low level services
as those
required services that are neccesary to create more complex high level
composed
services.Postprint (published version
La sodomia i el cos malat de les dones
El present article tĂ© com a objectiu analizar els discursos literaris, religiosos i mèdics que convergeixen en una de les obres cabdals en llengua catalana medieval: l’Espill (1460), de Jaume Roig. Primerament, cal no oblidar que el seu autor va ser un dels metges mĂ©s prestigiosos a la València quatrecentista, de manera que haurĂ de valorar-se el context cientĂfic que el nodreix; tampoc no pot oblidar-se, en segon lloc, la tradiciĂł misògina que forneix el seu extens poema narratiu. D’altra banda, voldria incidir en una cruĂŻlla cultural encara poc analitzada —força insòlita al seu temps— que Ă©s la vinculada a la sodomia com a “creació” femenina; hom valorarĂ les significacions de la seva construcciĂł, comparada a la lepra al mateix text
Sodomy and the Sick Body of Women
The aim of this article is to analyse the literary, religious and medical discourses that converge in one of the leading works in medieval Catalan: the Espill (Mirror) (1460), by Jaume Roig. Firstly, it should be remembered that the author was one of the most prestigious doctors in 15th century Valencia, so it should be judged in the scientific context that nurtured it. Nor should we forget, in second place, the misogynist tradition behind this long narrative poem. On the other hand, I would like to emphasise a cultural crossroads that was quite unusual in its time, and is as yet little studied, which is linked to sodomy as a female “creation”; I will assess the significance of this construction, compared with leprosy in the same text
An infrared study of galactic OH/IR stars. I. An optical/near-IR atlas of the Arecibo sample
In this paper we present optical and near-infrared finding charts, accurate
astrometry (~1") and single-epoch near-infrared photometry for 371 IRAS
sources, 96% of those included in the so-called Arecibo sample of OH/IR stars
(Eder et al. 1988; Lewis et al. 1990a; Chengalur et al. 1993). The main
photometric properties of the stars in the sample are presented and discussed
as well as the problems found during the process of identification of the
optical/near-infrared counterparts. In addition, we also identify suitable
reference stars in each field to be used for differential photometry purposes
in the future.
We find that 39% of the sources (144 in number) have no optical counterpart,
8 of them being invisible even at near infrared wavelengths. The relative
distribution of sources with and without optical counterpart in the IRAS
two-colour diagram and their characteristic near infrared colours are
interpreted as the consequence of the increasing thickness of their
circumstellar shells. Among the objects not detected at near infrared
wavelengths four non-variable sources are proposed to be heavily obscured
post-AGB stars which have just very recently left the AGB. Eight additional
objects with unusually bright and/or blue near-infrared colours are identified
as candidate post-AGB stars and/or proto-planetary nebulae.Comment: 28 pages, 9 figures, for associated finding charts see:
