since the emergence of the process-oriented approach to second language writing instruction two main questions have been what and how error feedback should be given to the students. the question of whether teachers should provide feedback on grammar in the writing assignments of english as a foreign language students, and if so how, has been a matter of considerable debate in the field of secon...

In this paper, an extension of algorithm for the implicit discretization a super-twisting sliding mode observer is presented. Implicit and explicit algorithms homogeneous differentiators, where no physical model information considered, are investigated in literature. This article studies behavior when considering models rather general class nonlinear systems. The discrete equations reformulated...

A numerical method using implicit surface representations is proposed to solve the linearized Poisson-Boltzmann equations that arise in mathematical models for the electrostatics of molecules in solvent. The proposed method used an implicit boundary integral formulation to derived a linear system defined on Cartesian nodes in a narrowband surrounding the closed surface that separate the molecul...

Recently an automatic solution to the problem of applying 2D textures to an implicit surface has been introduced [13]. The method derives a uv-texture coordinate system by tracing particles from the implicit surface to a support surface. In this paper we describe the adaptation of this algorithm to the BlobTree data structure. The BlobTreeprovides an implicit modelling system through a hierarch...

A flexible, scalable and affordable virtual reality software system architecture is proposed. This solution can be easily implemented on different hardware configurations: on a single computer or on a computer cluster. The architecture is aimed to be integrated in the workflow for solving engineering tasks and oriented towards presenting implicit object properties through multiple sensorial cha...

Four verbal implicit memory tests, word identification, word stem completion, word fragment completion, and anagram solution, were directly compared in one experiment and were contrasted with free recall. On all implicit tests, priming was greatest from prior visual presentation of words, less (but significant) from auditory presentation, and least from pictorial presentations. Typefont did not...

We develop a novel framework, the implicit hitting set approach, for solving a class of combinatorial optimization problems. The explicit hitting set problem is as follows: given a set U and a family S of subsets of U , find a minimum-cardinality set that intersects (hits) every set in S. In the implicit hitting set problem (IHSP), the family of subsets S is not explicitly listed (its size is, ...

introduction: children with attention deficit hyperactivity disorder have problem in sustain attention that is necessary for learning. the purpose of present study is comparing explicit and implicit memory in children with attention deficit disorder and typically developing children. material and methods: in present cross sectional study, fifteen children with attention deficit disorder compare...

This paper synthesizes the Balasian implicit enumeration approach to integer linear programming with the approach typified by LAND AND DOIG and by ROY, BEBTIER, AND NGHIEM. The synthesis results from the use of an imbedded linear program to compute surrogate constraints that are as 'strong' as possible in a sense slightly different from that originally used by GLOVBK. A simple implicit enumerat...

We study an implicit inhomogeneous linear differential-difference equation in the module of formal generalized functions over a commutative ring. prove well-posedness and find fundamental solution. obtain representation unique solution to form convolution given function. also consider second order differential arbitrary
