Improvements on the execution performance of a given application can be obtained simply by the use of more efficient algorithms, a better codification and by the selection of adequate compiling options. The present study aims to analyse these different scopes, and to apply this methodology to square matrix multiplication. The case study uses C language, the GCC compiler, and a reference algorit...

The Code Generation (CG) domain and its derivative domains, such as the CG56 domain (Motorola DSP56000) and the C language (CGC) domain, are used to generate code rather than to run simulations. Only the derivative domains are of practical use for generating code. The stars in the CG domain itself can be thought of as “comment generators”; they are useful for testing and debugging schedulers an...

abstractthe interference of the native language in acquiring a foreign language is unavoidable. in an attempt to explore the phenomenon why this occurs, the study was conducted in english as a foreign language writing. the study also investigated how the native language interference occurred in the writing process. in fact, this qualitative study explored the reasons and the process of native l...

A qualitative method and an in-depth interview have been applied to achieve the research goal. The information and data collected from the interviews have been analyzed using open coding and axial coding. Then, the initial indicators of the model of using e-ba...

Although Fortran is not a pleasant language to use, it does have the advantages of universality and (usually) relative efficiency. The Ratfor language attempts to conceal the main deficiencies of Fortran while retaining its desirable qualities, by providing decent control flow statements: statement grouping if-else and switch for decision-making while, for, do, and repeat-until for looping brea...

CRM information systems are valuable tools for enterprises. But CRM implementation projects are risky and present a high failure rate. In this paper we regard CRM implementation projects as services that could be greatly improved by addressing them in a methodological way that can be designed with the help of tools such as SysML. Here we introduce and comment on our first experience on the use ...

We are developing a system in which a user can control virtual agents through natural language dialogue. We particularly focus on the semantic analysis of spatial expressions in natural language instructions. Spatial expressions are relative to the speaker’s viewpoint and the indicated positions can change dynamically. In this paper we propose a semantic representation using lambda structures. ...
