the present study was designed to investigate the impact of applying fill-in-the-map and construct-a-map techniques on efl learners’ knowledge of tenses. to this end, sixty efl elementary female students, who were selected based on their performance on a standardized teacher-made proficiency test, were randomly assigned into two equal experimental and control groups. in order to be convinced of...

Rough surfaced implants have been reported to favor early bone healing than smooth surfaced implants. Among various methods introduced to roughen the implant surface, coating with calcium phosphate(CaP) is one of them. The purpose of this study was to evaluate the bone healing response of anodized implants with two different coating thickness of CaP(200 nm and 500 nm) deposited by ion beam assi...

Deciding test data volume is a major challenge in present System on Chip (SoC) design. Compaction of test data volume results in high compression ratio. Entropy analysis plays a vital role in such cases. Entropy is measurement of the amount of information contained in the data set. Entropy calculations tell the need of how much test data vector that can be compressed. This paper is based on fin...

We study the problem of providing recommendations to students that help them in their studies. To address this problem, we present an approach of providing recommendations of remedial learning materials to students that fill the gaps in their knowledge of the subject in the courses they take. According to this method, we first identify gaps in the student’s mastery of various course topics. We ...

This paper proposes an analytical method for performance evaluation and optimization of a production-distribution system composed of a warehouse supplied from an upstream manufacturing plant. Customer orders arrive randomly with random order size and the production capacity is finite. Transportation time from plant to warehouse is fixed. The analytical approach needs only the first two moments ...

An Apollonian configuration of circles is a collection of circles in the plane with disjoint interiors such that the complement of the interiors of the circles consists of curvilinear triangles. One well studied method of forming an Apollonian configuration is to start with three mutually tangent circles and fill a curvilinear triangle with a new circle, then repeat with each newly created curv...
