Engineering Topological Nodal Line Semimetals in Rashba Spin-Orbit Coupled Atomic Chains
2019
We study an atomic chain in the presence of modulated charge potential and modulated Rashba spin-orbit coupling (RSOC) of equal period. We show that for commensurate periodicities $\lambda=4 n$ with integer $n$, the three-dimensional synthetic space obtained by sliding the two phases of the charge potential and RSOC features a topological nodal line semimetal protected by an antiunitary particle-hole symmetry. The location and shape of the nodal lines strongly depend on the relative amplitude between the charge potential and RSOC.
Languages with mismatches and an application to approximate indexing
2005
In this paper we describe a factorial language, denoted by L(S, k,r), that contains all words that occur in a string 5 up to k mismatches every r symbols. Then we give some combinatorial properties of a parameter, called repetition index and denoted by R(S,k,r), defined as the smallest integer h ? 1 such that all strings of this length occur at most in a unique position of the text S up to k mismatches every r symbols. We prove that R(S, k, r) is a non-increasing function of r and a non-decreasing function of k and that the equation r = R(S, k, r) admits a unique solution. The repetition index plays an important role in the construction of an indexing data structure based on a trie that rep…

Finite automata on timed ω-trees
2003
AbstractIn the last decade Alur and Dill introduced a model of automata on timed ω-sequences which extends the traditional models of finite automata. In this paper, we present a theory of timed ω-trees which extends both the theory of timed ω-sequences and the theory of ω-trees. The main motivation is to introduce a new way of specifying real-time systems and provide tools for studying decidability problems in related fields. We focus on the decision problems and their applications in system verification and synthesis.
RECOGNIZABLE PICTURE LANGUAGES
1992
The purpose of this paper is to propose a new notion of recognizability for picture (two-dimensional) languages extending the characterization of one-dimensional recognizable languages in terms of local languages and alphabetic mappings. We first introduce the family of local picture languages (denoted by LOC) and, in particular, prove the undecidability of the emptiness problem. Then we define the new family of recognizable picture languages (denoted by REC). We study some combinatorial and language theoretic properties of REC such as ambiguity, closure properties or undecidability results. Finally we compare the family REC with the classical families of languages recognized by four-way a…

Frisian as an Endangered Language: An Overview
2019
The main goal of the paper is to answer the questions whether Frisian can be referred to as an endangered language and if it managed to survive the constant influence of the surrounding larger cultures and languages. The first point to be analyzed is the geographic distribution of Frisian. The second issue to be considered is the historical and present cultural and social status of the Frisian language. The third matter to be analysed is the lexical variety of Frisian language and its complexity, which made its survival possible. The article takes the diachronic perspective and expounds upon all the mentioned factors and their role in the preservation of Frisian until today. The paper prese…
Process support in MetaCASE: implementing the conceptual basis for enactable process models in MetaEdit+
2002
This study concerns the support of information system analysis and design process in a metaCASE environment. We see a process as highly, evolutionary and unstructural in nature, thus requiring the tailorability of user process models and their conceptual basis, process modelling language (PML). In addition to the flexibility needed for guiding various system developers, the CASE environment needs to be enacted using strictly defined environment actions. A distinction between user and environment processes is made, hence distinguishing also their conceptual basis and modelling requirements. The study depicts the realisation of the basic concepts and tools required in modelling a PML and the …
FLIPPING THE ESL CLASSROOM.STRATEGIES FOR COMMUNICATION AND INCLUSION
2015
One of the most interesting and recent teaching approach that is attracting insistently both academic and teaching environments, is the Flipped Classroom, or Inverted Classroom. The class, where there is a turning over of the activities with the purpose of making both lessons and individual study more interesting and productive is “flipped”. This approach is fundamentally based on three issues: 1) a conscious use of technologies for learning/teaching purposes, 2) a revision of learning times, 3) the importance of the educational relationship. The flipped is also an answer to the teacher's aim to solve problems related to the learning process, that means, to create the best condition through…
