Towards the design and implementation of aspect-oriented programming for spreadsheets

A spreadsheet usually starts as a simple and singleuser software artifact, but, as frequent as in other software systems, quickly evolves into a complex system developed by many actors. Often, different users work on different aspects of the same spreadsheet: while a secretary may be only involved in adding plain data to the spreadsheet, an accountant may define new business rules, while an engineer may need to adapt the spreadsheet content so it can be used by other software systems.Unfortunately,spreadsheetsystemsdonotoffermodular mechanisms, and as a consequence, some of the previous tasks may be defined by adding intrusive “code” to the spreadsheet. In this paper we go through the design and implementation of an aspect-oriented language for spreadsheets so that users can work on different aspects of a spreadsheet in a modular way. For example, aspects can be defined in order to introduce new business rules to an existing spreadsheet, or to manipulate the spreadsheet data to be ported to another system. Aspects are defined as aspect-oriented program specifications that are dynamically woven into the underlying spreadsheet by an aspect weaver. In this aspect-oriented style of spreadsheet development, differentusers develop,orreuse,aspects withoutaddingintrusive code to the original spreadsheet. Such code is added/executed by the spreadsheet weaving mechanism proposed in this paper.

Metaphorisms in programming

This paper introduces the metaphorism pattern of relational specification and addresses how specification following this pattern can be refined into recursive programs. Metaphorisms express input-output relationships which preserve relevant information while at the same time some intended optimization takes place. Text processing, sorting, representation changers, etc., are examples of metaphorisms. The kind of metaphorism refinement proposed in this paper is a strategy known as change of virtual data structure. It gives sufficient conditions for such implementations to be calculated using relation algebra and illustrates the strategy with the derivation of quicksort as example.

Final report detailed description - NET Station: shaping radio for web environment

In more scientific terms, NET Station contributed to: - discuss in theoretical terms the role radio still play in contemporary societies; - examine how audiences are using sound resources on the Web; - draw up a new theoretical framework for the study of the reconfiguration of radio language on the Internet;acknowledge that people are not abandoning radio as a medium; the survey applied by the team demonstrated that there is a complementariness between traditional radio and radio on the Internet; - understand that people expect more interactivity, more opportunities to participate in content production and more diversity of contents. These results were shared with editors responsible for Portuguese radio and might influence the offer made available by these radio corporations from now on; - demonstrate that the Internet is underexplored in terms of sound and acoustic communication; - promote the production of new sound narratives to be available on the Internet;
