On the Influence of Antioxidants and Recycled MgO–C Source Material on the Mechanical Properties of Carbon‐Bonded Magnesia Refractories

Advanced Engineering Materials, EarlyView.
The presented study focuses on the fracture behaviour of carbon‐bonded magnesia MgO–C refractories, where environmentally friendly fructose, collagen and lignin serve as temporary binding agents. The partial substitution of the source material with recycled MgO–C reduces the fracture resistance, which can be counteracted by the additional introduction ...

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

Advanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

Investigation of Thermo‐Chemical Processes in Commercial MgO‐C Refractory Bricks With and Without MgO‐C Recyclate at Elevated Temperatures

Advanced Engineering Materials, EarlyView.
This study investigates thermo‐chemical processes during high‐temperature testing of two commercial MgO‐C brick grades, one containing 47.5 wt.% MgO‐C recyclate. Using ETV, DTA/TG‐MS, XRD, and SEM/EDS/EBSD, mechanisms such as carbothermal reduction of magnesia, impurity incorporation into the secondary MgO surface layer, and calcium‐rich phase ...

Adaptive hybrid brain-computer interaction: Ask a trainer for assistance!

2014 36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2014
In applying mental imagery brain-computer interfaces (BCIs) to end users, training is a key part for novice users to get control. In general learning situations, it is an established concept that a trainer assists a trainee to improve his/her aptitude in certain skills.

Trainer Opinions of Selected Computer-Based Training Methods

Journal of Education for Business, 2002
Abstract In this study, the author surveyed 138 business professors concerning their opinions of various training methods. The respondents' ratings of computer-based training methods, such as Web-based ones, were lower than the ratings they gave more participative methods, such as internships and live cases.

Teaching Vowel Articulation with the Computer Vowel Trainer Methodology and Results

International Journal of Audiology, 1981
The Computer Vowel Trainer (CVT) uses linear prediction to estimate and display the shape of the speaker's vocal tract during an utterance. The assessment of the CVT was carried out over a period of three years with 14 profoundly deaf children divided into an experimental and a matched control group.

A Digital Computer for Use in an Operational Flight Trainer

IRE Transactions on Electronic Computers, 1955
The requirements for a digital computer for use in an operational flight trainer are presented with emphasis being placed on the real-time aspects of the problem. The general purpose digital computer is shown to be inadequate for this purpose and a special purpose digital computer is described which meets the requirements.

A micro-computer based trainer for pure-tone audiometry

International Journal of Audiology, 1986
A micro-computer based system to simulate patient performance on pure-tone audiometry has been developed, which in conjunction with a dummy audiometer allows easy development of a student training facility. The system can be easily configured to realistically and comprehensively represent a wide range of hearing losses.

Measuring Computer Literacy of Teacher Trainers

Journal of Educational Computing Research, 1988
The creation of sufficient numbers of trainers prepared to train teachers in the use of computers has been a difficult task. Work by the Training Modules for Trainers Project has been addressing this problem using a trainer of trainers model. A core group of fifty trainers has been created by the project, in addition to a series of fourteen resource ...
