Inglés contra valenciano. La introducción del multilingüismo en el sistema lingüístico educativo valenciano
2017
Aquest treball tracta sobre l’ús polític de les llengües i, singularment, centra l’atenció en el programa de plurilingüisme educatiu posat en marxa pel govern de la Generalitat Valenciana el 2012. Considerem que aquesta iniciativa obeïa una voluntat conscient del partit en el govern (PP) de minoritzar més encara el valencià davant el castellà, amb l’excusa de millorar el coneixement d’anglés. Ara bé, la iniciativa valenciana no és un fet aïllat, s’emmarca dins d’una proposta política d’àmbit estatal orientada a garantir la preeminència del castellà i debilitar le polítiques lingüístiques educatives favorables a les altres llengües espanyoles. Val a dir que fem el treball des de l'òptica com…
On the Size Complexity of Deterministic Frequency Automata
2013
Austinat, Diekert, Hertrampf, and Petersen [2] proved that every language L that is (m,n)-recognizable by a deterministic frequency automaton such that m > n/2 can be recognized by a deterministic finite automaton as well. First, the size of deterministic frequency automata and of deterministic finite automata recognizing the same language is compared. Then approximations of a language are considered, where a language L′ is called an approximation of a language L if L′ differs from L in only a finite number of strings. We prove that if a deterministic frequency automaton has k states and (m,n)-recognizes a language L, where m > n/2, then there is a language L′ approximating L such that L′ c…
Monadic second-order logic over pictures and recognizability by tiling systems
1994
We show that a set of pictures (rectangular arrays of symbols) is recognized by a finite tiling system if and only if it is definable in existential monadic second-order logic. As a consequence, finite tiling systems constitute a notion of recognizability over two-dimensional inputs which at the same time generalizes finite-state recognizability over strings and matches a natural logic. The proof is based on the Ehrenfeucht-FraIsse technique for first-order logic and an implementation of “threshold counting” within tiling systems.
Monadic Second-Order Logic over Rectangular Pictures and Recognizability by Tiling Systems
1996
Abstract It is shown that a set of pictures (rectangular arrays of symbols) is recognized by a finite tiling system iff it is definable in existential monadic second-order logic. As a consequence, finite tiling systems constitute a notion of recognizability over two-dimensional inputs which at the same time generalizes finite-state recognizability over strings and also matches a natural logic. The proof is based on the Ehrenfeucht–Fraisse technique for first-order logic and an implementation of “threshold counting” within tiling systems.
Recent results on syntactic groups of prefix codes
2012
International audience; We give a simplified presentation of groups in transformation monoids. We use this presentation to describe two recent results on syntactic groups of prefix codes. The first one uses Sturmian words to build finite bifix codes with a given permutation group as syntactic group. The second one describes a class of prefix codes such that all their syntactic groups are cyclic.
A Generalization of Girod's Bidirectional Decoding Method to Codes with a Finite Deciphering Delay
2012
Girod’s encoding method has been introduced in order to efficiently decode from both directions messages encoded by using finite prefix codes. In the present paper, we generalize this method to finite codes with a finite deciphering delay. In particular, we show that our decoding algorithm can be realized by a deterministic finite transducer. We also investigate some properties of the underlying unlabeled graph.
Some Decision Results on Nonrepetitive Words
1985
The paper addresses some generalizations of the Thue Problem such as: given a word u, does there exist an infinite nonrepetitive overlap free (or square free) word having u as a prefix? A solution to this as well as to related problems is given for the case of overlap free words on a binary alphabet.
Translingual Practices in Global Business : A Longitudinal Study of a Professional Communicative Repertoire
2018
This chapter draws on a longitudinal ethnographic study of a Finnish engineer’s communicative repertoire that develops in the process of professional migration. The participant first works as a factory intern in Germany, then as a project engineer and project manager in Finland, and latterly as an operations manager in China. Here, repertoire is viewed through dynamic and flexible translingual practices, in which people follow, appropriate and invent norms, combine and shuttle between languages, ways of speaking, semiotic resources and modalities in the transnational work space in order to meet, interact, make meaning and build relationships and, ultimately, do their jobs. The data selected…

Biznesa procesu modelēšana, izmantojot metamodelēšanas paņēmienus : kopsavilkums
2007
Darba tēma ir saistīta ar biznesa procesu vadības sistēmu izstrādi. Šajā darbā biznesa procesu modelēšanas problēmas ir risinātas, izmantojot metamodelēšanas paņēmienus. Metamodelēšana ļauj dažādus biznesa modelēšanas aspektus aplūkot vienotā un vispārīgā formā, tai pat laikā nezaudējot precīzu jēdzienu nozīmi. Galvenie pētījumu rezultāti ir sekojoši: Izstrādāts vienots biznesa procesu un to apkārtnes metamodelis, kas parāda biznesa modelēšanas jēdzienus un to saistību. Izstrādāta biznesa modeļu jēdzienu kartēšanas metode jēdzienu kartēšanai no viena domēna uz vairākām modelēšanas valodām. Izstrādāta precīza Unified Modeling Language Aktivitāšu diagrammas (UML AD) izpildes semantika, izmant…
