A High Level Language for Pyramidal Architectures
1986
In the paper are described the syntax and some implementation features of a high level language for pyramidal architectures called Pyramid B Language (PCL). The language is an extension of the B and include data type, set of instructions and builtin functions oriented to the pyramidal architectures. Some notes on the implementation for the PAPIA machine are also given.
Construction and Implementation of LR(1) Parsers
1990
This chapter is devoted to the practical issues involved in the construction and use of deterministic LR(1) parsers. We shall show how the practical versions of LR (1) parsers, most notably the LALR (1) parsers, can be constructed efficiently, and we shall present methods for encoding LR(1) parsers as efficient RAM programs. Two versions of RAM program implementation are considered: in the first implementation the parsing program is table-driven, that is, the rules of the parser are encoded in a two-dimensional array which is simulated by a program body; in the other implementation the tabular information is further transformed into a set of program statements.
Informatics in Descriptive Geometry. Didactic Experience
2009
This study is centred in the environment of the research into solutions of the problems of graphic representation, expressing theoretical considerations which allow the carrying out of geometric-descriptive procedures decoded in informatics language, for implementing CAD commands.
From the descriptive geometry to the informatics language - Case study
2010
This study is centred in the environment of the research into solutions of the problems of graphic representation, expressing theoretical considerations which allow the carrying out of geometric-descriptive procedures decoded in informatics language, for implementing CAD commands. The solution of these problems requires a reliable command of stereometry and descriptive geometry and it can extend remarkably the level of external geometric competences. The implementation of the means of ICT has brought a higher effectiveness of graphing mapping processes. In the informatics field, the advent of software dedicated to computerized representation has increased the possibilities of investigation …
HERMIA: An Heterogeneous and Reconfigurable Machine for Image Analysis
1990
In this paper is described the general architecture of an Heterogeneous and Reconfigurable Machine for Image Analysis (HERMIA); the first prototype of the system has been developed at the University of Palermo. Conventional hardware has been used in order to emulate the machine and evaluate the system performance Preliminary results are presented and discussed.
E-LEARNING AND ART OF PROGRAMMING: A CONTEXT ORIENTED TO
2017
Coding or programming is very important for a number of tasks and this is true not only in problem solving but also in the computer science and over. Many skills have to be acquired before to have a high familiarity degree with this science. In the studies for methods of coding, students have a great problem for understanding on how to solve and to develop algorithms in a rational way, thus the expertise on how to solve and to develop algorithms is the most difficult to acquire for all students in whatever age. This paper introduces the prototype of a framework able to running in the web space and to be supported by different devices and browsers, useful to integrate a number of collaborati…
Application of EαNets to Feature Recognition of Articulation Manner in Knowledge-Based Automatic Speech Recognition
2006
Speech recognition has become common in many application domains. Incorporating acoustic-phonetic knowledge into Automatic Speech Recognition (ASR) systems design has been proven a viable approach to rise ASR accuracy. Manner of articulation attributes such as vowel, stop, fricative, approximant, nasal, and silence are examples of such knowledge. Neural networks have already been used successfully as detectors for manner of articulation attributes starting from representations of speech signal frames. In this paper, a set of six detectors for the above mentioned attributes is designed based on the E-αNet model of neural networks. This model was chosen for its capability to learn hidden acti…
Inferring Business Rules from Natural Language Expressions
2014
This paper proposes a mapping technique for automatically translating rules expressed in a format based on natural language, i.e. Semantics of Business Vocabulary and Business Rules (SBVR) standard, into production rules that can be executed by a computer (i.e. Rule engine). The proposed approach achieves a twofold purpose: on the one hand non IT skilled people (i.e. Domain expert) can effectively focus on business rules definition by using statements in natural language, and on the other hand the IT staff will have to manage business rules in a format ready to be executed by a rule engine. The main goal is to overcome some weaknesses in the software development process that could produce i…
XPL, a Presentation Language based on User Interface Design Pattern
2007
The great diversity of presentations in software applications deals with fulfillment of various type of graphic interface constructions related to different programming Languages. Moreover, in the Internet era html pages play a main role because of the increasing complexity of Web applications. In Software Engineering, the use of design patterns is proven remarkable for the design and reuse of software components. Visual Design. Patterns (ViDP) are useful to define interaction schemas between. user and computer. By the some token, visual design. patterns are useful to incorporate common interfaces of interaction, schemas between user and computer. This paper describes the eXtensible Present…
Multi-Platform Agent Systems with Dynamic Reputation Policy Management
2011
Open, distributed multi-platform agent systems require new management approaches for resources and data secure access. In this paper a Jade-S based multi-platform agent system implementing dynamic reputation policy management is proposed. The implemented extension deals with biometrics, X-Security, DES cryptography and agent reputation. With more details, the proposed reputation management system helps to assess the agent's behavior and reliability, in order to select trusted agents. This is made possible by the knowledge that agents are able to acquire, over time, and that allows them to choose the best solution using own intelligence in total autonomy.
