Hardware-in-the-Loop (HIL) testing is proposed as a new methodology for verification and certification of marine control systems. Formalizing such testing necessitates the development of a vocabulary and set of definitions. This paper treats these issues by constructing a framework suitable for industrial HIL test applications and certification of marine systems.

A nice trick for studying the billiard flow in a rational polygon is to unfold the polygon along the trajectories. This gives rise to a translation or half-translation surface tiled by the original polygon, or equivalently an Abelian or quadratic differential. Veech surfaces are a special class of translation surfaces with a large group of affine automorphisms, and interesting dynamical propert...

This study intended to inspect the possible effects of teaching English lexical clusters on speaking accuracy of Iranian EFL intermediate learners. Also it examined the influence of gender on the effect of teaching English lexical clusters on speaking accuracy of the same learners. 41 male and female EFL intermediate learners, studying  English at intermediate level at Zabankade Institute in Te...

Attribute-based Access Control (ABAC) policies are based on mutually processable policy attributes. Assigned permissions in such policies need to be reflected or combined with organisational constraints. Best practice in information security dictates having the operational need to access a particular information artifact independent from the function of the specific application systems. Consequ...

There are several terms used to describe the same phenomenon, and the same term is used to describe different phenomena. It confuses us and makes metacognition miracle. What is metacognition? We have been tackling the problem by defining our own criteria for determining what metacognition is or what cognition is. Through a survey of related works, we try to define the criteria and classify skil...

This study sought to examine the effects of a teacher-designed, differentiated instructional model on the reading skills (i.e., fluency and vocabulary) of struggling third grade readers. Participants included eight struggling third grade students in the intervention classroom and a comparison group of eight struggling third grade students in a control classroom. Participants completed measures ...

According to Oxford (1990), strategies are steps taken by students to enhance their own learning. This research attempted to investigate the impact of teaching vocabulary learning strategies on short-term and long-term retention of vocabulary items. The sample participants included 303 females randomly selected from one all-female governmental Pre-university school (PUC) in Iran. They were then...
