Commentary on Jakab's Ineffability of Qualia
Zoltan Jakab has presented an interesting conceptual analysis of the ineffability of qualia in a functionalist and classical cognitivist framework. But he does not want to commit himself to a certain metaphysical thesis on the ontology of consciousness or qualia. We believe that his strategy has yielded a number of highly relevant and interesting insights, but still suffers from some minor inconsistencies and a certain lack of phenomenological and empirical plausibility. This may be due to some background assumptions relating to the theory of mental representation employed. Jakab's starting assumption is that there is no linguistic description of a given experience such that understanding the description would result in someone who has never had the experience being described undergoing an experience of that type. (In terms of the well-known Mary case: No description could reveal what colors are like to Mary.) This is what Jakab means by the ineffability of qualia. And this is Jakab's explanation: Understanding in the standard sense involves our linguistic- conceptual abilities; but our linguistic-conceptual abilities are notinvolved in undergoing simple sensory experiences; so they cannot deliver knowledge by acquaintance, which means linguistic descriptions of sensory experiences cannot result in someone who understands the description undergoing the experience being described. (We do not agree with the assumption that our linguistic-conceptual abilities are not at all involved in undergoing simple sensory experiences; such processes can be involved in undergoing simple sensory experiences, but they need not be the only thinginvolved in undergoing simple sensory experiences; in undergoing simple sensory experiences something else is involved which cannot be captured by descriptions. The crucial point is that descriptions do not give us knowledge by acquaintance.
Blue - A Language for Teaching Object-Oriented Programming
Teaching object-oriented programming has clearly become an important part of computer science education. We agree with many others that the best place to teach it is in the CS1 introductory course. Many problems with this have been reported in the literature. These mainly result from inadequate languages and environments. Blue is a new language and integrated programming environment, currently under development explicitly for object-oriented teaching. We expect clear advantages from the use of Blue for first year teaching compared to using other available languages. This paper describes the design principles on which the language was based and the most important aspects of the language itself
Influence of Models on the Existence of Anisotropic Self-Gravitating Systems
This paper aims to explore some realistic configurations of anisotropic
spherical structures in the background of metric gravity, where is
the Ricci scalar. The solutions obtained by Krori and Barua are used to examine
the nature of particular compact stars with three different modified gravity
models. The behavior of material variables is analyzed through plots and the
physical viability of compact stars is investigated through energy conditions.
We also discuss the behavior of different forces, equation of state parameter,
measure of anisotropy and Tolman-Oppenheimer-Volkoff equation in the modeling
of stellar structures. The comparison from our graphical representations may
provide evidences for the realistic and viable gravity models at both
theoretical and astrophysical scale.Comment: 23 pages, 13 figures, version accepted for publication in European

A Model for Configuration Management of Open Software Systems
The article proposes a model for the configuration management of open
systems. The model aims at validation of configurations against given
specifications. An extension of decision graphs is proposed to express
specifications. The proposed model can be used by software developers to
validate their own configurations across different versions of the components,
or to validate configurations that include components by third parties. The
model can also be used by end-users to validate compatibility among different
configurations of the same application. The proposed model is first discussed
in some application scenarios and then formally defined. Moreover, a type
discipline is given to formally define validation of a configuration against a
system specificationComment: 13 page
Existence of Compact Structures in Gravity
The present paper is devoted to investigate the possible emergence of
relativistic compact stellar objects through modified gravity. For
anisotropic matter distribution, we used Krori and Barura solutions and two
notable and viable gravity formulations. By choosing particular
observational data, we determine the values of constant in solutions for three
relativistic compact star candidates. We have presented some physical behavior
of these relativistic compact stellar objects and some aspects like energy
density, radial as well as transverse pressure, their evolution, stability,
measure of anisotropy and energy conditions.Comment: 27 pages, 13 figures, version accepted for publication in European
