An instrument to produce surface colors of continuously variable brightness

Design of Continuously Variable Transmission (CVT) with Metal Pushing Belt and Variable Pulleys

Nowadays, automakers have invested in new technologies in order to improve the efficiency of their products. Giant automakers have taken an important step toward achieving this objective by designing continuously variable transmission systems (CVT) to continuously adapt the power of the engine with the external load according to the optimum efficiency curve of e...

Modeling and Sensitivity Analysis of Full Toroidal Continuously Variable Transmission

an experimental study on full toroidal continuously variable transmission system

abstract: a continuously variable transmission (cvt) is a transmission which may change step less by way of an infinite variety of effective gear ratios between maximum and minimum values. this contrasts with different mechanical transmissions that solely permit just a few different distinct gear ratios to be selected. continuously variable transmissions (cvts) are mechanical devices that allow...

Operationalization of Formative Assessment in Writing: An Intuitive ‎Approach to the Development of an Instrument

The current study aimed to develop a Formative Assessment of Writing (FAoW) instrument through operationalizing Black and Wiliam’s (2009) Formative Assessment (FA) and Hattie and Timperley’s (2007) feedback model. Following intuitive approach of scale construction (Hase & Goldberg, 1967), a comprehensive review of the literature was undertaken, and 30 Likert scale items were devised.  The items...

Developing an instrument to measure effective factors on clinical learning

Introduction: Although nursing students spend a large partof their learning period in the clinical environment, clinicallearning has not been perceived by its nature yet. To develop aninstrument to measure effective factors on clinical learning innursing students.Methods: This is a mixed methods study performed in 2 steps.First, the researchers defined “clinical learning” in nursingstudents thr...
