The design of complex VLSI circuits is typically based on the decomposition of the routing area into regions to be connected independently of one another. This approach requires the use of a tool for the definition of these regions and their ordering through a suitable interconnection sequence. In this paper, an algorithm is proposed that is...

The macrocell approach to the design of VLSI integrated circuits needs a tool for the solution of the switchbox problem, where terminals lie on all the edges of a generic rectilinear region. In the paper, such a problem is thoroughly analysed and a two-layer symbolic router is proposed, which is able to successfully route very dense examples of...

An abstract hypercube architecture made up of computing elements (nodes) has been simulated, in which each node is able to manage both the computation of data and the communications with the other nodes of the architecture. This is achieved by providing each node with a proper set of instructions, which are broadcast (according to the SIMD...

The implementation and evaluation of several algorithms for the solution of the partitioning problem has been described. The partitioning is performed according to the main strategy of separating, at each step, the elements into two groups looking for the minimization of the connections between elements belonging to different groups. In...

In this paper we describe some teaching methods to promote the acquisition of mathematical meanings through the use of money and suggest some software that implement them. Significant results have been obtained on some children of the elementary and middley schools with mild to moderate cognitive difficulties.

This paper describes a powerful pseudo-syllabic paradigm for improving the efficiency of typing in languages with transparent orthography (i.e., languages with highly regular correspondence of orthography and phonetics). By adopting a novel orthogonal framework, keyboards are defined as 2-D regular arrays of keys. Non-expert users can fast and...

This paper concerns a specific learning difficulty that children with Cerebral Palsy face when dealing with the logicalmathematical field, i.e. the mathematical modelling of the temporal dimension. Following analysis of the problems related to this type of difficulty, some methodological indications are provided for overcoming it. Subsequently...

The new ICT technologies can play an important role in aiding motor-impaired children by cerebral palsy to overcome some operational and cognitive difficulties in the logical-linguistic field, which concern autonomous writing and semantic understanding of written texts. In this paper it has been discussed the active role that can be played by...

In this paper we present a cooperative learning experience teaching Mathematics iat the University of Genoa. In particular, we present some ideas for a cooperative e-learning based on specific teaching methodologies and using a virtual laboratory approach. The virtual lab we present uses AulaWeb, which is an on-line support service at the...

In this article we present, through some case studies, a learning pathway for the cognitive development of children and adolescents with cognitive or neuromotor disabilities. This learning path uses some methodologies and some software programs within the field of experience regarding the use of money. The goal is to allow the person to...

This paper addresses the problem of loop iteration number estimation, applied to linear loops. This is important to statically put an upper bound on the execution time of real-time systems and implement timing constraint verification. In our approach, matrix calculation is applied to derive the analytical equation that holds the number of...

SKIP version 1.2 (Software Keyboard for Impaired Users; in Italian: Tastiera Software per Utenti Disabili) is a flexible framework for implementing virtual keyboards for improving the efficiency of typing by motor-impaired or non-expert users. To this aim, a powerful orthogonal framework has been used in which the keyboard is defined as a 2-D...

The program ERG (Easy Reading Glasses) has been studied and implemented to help in reading dyslexic people and more generally people with significant reading difficulties. This is obtained by expanding in a specific screen area the textual data contained in two screen areas containing web pages and texts. In fact, the text present in an...

In this paper some guidelines are described for a laboratory approach to address the difficulties in learning Mathematics. The main objective of this approach is to achieve a better understanding of meanings, in order to obtain useful and durable learning experiences. The proposed guidelines are of methodological nature and can be adapted to...

This paper proposes a pseudo-syllabic soft keyboard for the Croatian language. The orthogonal keyboard layout makes it possible to improve typing efficiency in terms of keystroke saving, and is based on a highly ordered arrangement of pseudo-syllabic keys. The positions of the consonant and vowel graphemes that constitute a pseudo-syllable are...

SKIP version 0.1 (Software Keyboard for Impaired Users; in Italian: Tastiera Software per Utenti Disabili) is the first prototype of a software keyboard for improving the efficiency of typing in languages with transparent orthography (i.e., languages with highly regular correspondence of orthography and phonetics) by impaired users or...

In this paper, starting from our experience with our daughter Margherita, who is affected by spastic tetraparesis due to childish cerebral paralysis with motor and visuo-spatial coordination problems, we propose the analysis of some problems concerning the learning of Mathematics to children with motor disability during the first years of...

In this paper a new technique is described to increase the writing speed by disabled users on hardware and software keyboards. The keyboard layout is organized as a bidimensional matrix of keys and allows to access the pseudo-syllables associated to the keys in a direct and intuitive way, and without the necessity to perform a complete visual...

In this paper we show how the recovery of cognitive problems can be obtained through a learning path in the economic field. The starting point of this path is the first contact with the experimental reality in the economic field, which then can find a significant boost in the use of the proposed educational software and subsequently in the use...

SKIP version 0.3 (Software Keyboard for Impaired Users; in Italian: Tastiera Software per Utenti Disabili) is an improved version of a software keyboard for improving the efficiency of typing in languages with transparent orthography (i.e., languages with highly regular correspondence of orthography and phonetics) by impaired users or...

The program SAGE (in Italian: Strumento per l'Apprendimento della Geometria Elementare) has been realized as an assistive technology software tool for students with learning disabilities in the mathematical field, and in particular concerning the management of basic geometric entities and operations. In fact, the program allows the student to...

This paper describes a three-layer maze router for chip-planning applications. The router contains a general and flexible algorithm to wire connections. It is also shown how this algorithm can effectively help to choose better heuristics in order to solve routing problems.
