As language learners scale up in terms of speaking proficiency, they expand the volume of expressions in the target language that they can use in a robust fashion, combining vocabulary and syntactic structures into novel constructions and transferring them to new contexts. In the ISLET Project, sponsored by the Office of Naval Research (ONR), we have developed a strategy for allowing a dialog-r...

We deene a new type of recurrence equation called \Simple Indexed Recurrences" (SIR). In this type of equation, ordinary recurrences of the form Xi] = opi(Xi ? 1]; Xi]) i = 1 : : : n are generalized to Xg(i)] = opi(Xf(i)];Xg(i)]), where f; g : f1 : : : ng 7 ! f1 : : : mg and g is distinct. This enables us to model sequential loops of the form for i = 1 to n Xg(i)] = opi(Xf(i)];Xg(i)]); as a seq...

MOTIVATION With the emergence of genome-wide expression profiling data sets, the guilt by association (GBA) principle has been a cornerstone for deriving gene functional interpretations in silico. Given the limited success of traditional methods for producing clusters of genes with great amounts of functional similarity, new data-mining algorithms are required to fully exploit the potential of ...

The studies on the merits of processing instruction (PI) and output-based instruction (OI) have mostly treated the two approaches as mutually exclusive. To address the potentials of combining interpretation and production activities, this research compared the two isolated approaches of PI and OI with two combined approaches in which processing and output tasks were used in two opposite orders ...

 This research aims to 1). analyze the level of Arabic proficiency in KMA 183 text book from perspective ACTFL, 2). Knowing urgency arrangement material textbook on language proficiency. 3) describe implications analysis based ACTFL guidelines. The is library by presenting data, documents and other supporting files with a qualitative descriptive approach, using content techniques,...

The validation of ability scales describing multidimensional skills is always challenging, but not impossible. This study applies a multistage, criterion‐referenced approach that uses a framework of aligned texts and reading tasks to explore the validity of the ACTFL and related reading proficiency guidelines. Rasch measurement and statistical analyses of data generated in three separate langua...

The “Durability Index” (DI) performance-based approach, developed in South Africa, involves the application of early-age concrete test methods together with service life prediction models, and links material properties directly expected reinforced (RC) structures under various environmental conditions. Oxygen Permeability Index (OPI) DI is based on permeation relates to carbonation concrete. As...

This paper presents an instruction scheduling algorithm based on the Subgraph Isomorphism Problem. Given a Directed Acyclic Graph (DAG) G1, our algorithm looks for a subgraph G2 in a base graph G2, such that G ′ 2 is isomorphic to G1. The base graph G2 represents the arrangement of the processing elements of a high performance computer architecture named 2D-VLIW and G2 is the set of those proce...
