Opis:
As many research focused on robustness methodology, this paper discuss on how to implement these methodology concept from the management perspective. Guidelines and appropriate strategies are discussed on Quality Engineering (QE) implementation in an organization and experimentation. Firstly, the experience of a company implementing QE is presented. Secondly, the practical data of a laboratory experiment is discussed in order to relate between the experimental result and requirement in industry. The QE implementation is explained on the strategies used in tackling organization problems. Optimization of peel adhesion strength test is carried out to propose the feasibility of experimental design tools. QE methodology between the practical case and company's case study is compared. Finally, through the QE implementation in organization and method applied in experimental design, a framework is proposed for QE methodology. QE implementation is presented from two sources, from a company and practical case study point of view. It helps a researcher or engineer applies the management strategy and engineering tool to ensure product robustness.

MUSHRA
Opis:
The multi-stimulus test with hidden reference and anchors (MUSHRA) is commonly used for subjective quality assessment of audio systems. Despite its wide acceptance in scientific and industrial sectors, the method is not free from bias. One possible source of bias in the MUSHRA method may be attributed to a graphical design of its user interface. This paper examines the hypothesis that replacement of the standard multi-slider layout with a single-slider version could reduce a stimulus spacing bias observed in the MUSHRA test. Contrary to the expectation, the aforementioned modification did not reduce the bias. This outcome formally supports the validity of using multiple sliders in the MUSHRA graphical interface.

Opis:
Recyclability is one of the great features of aluminium and its alloys. However, it has been typically considered that the secondary aluminium quality is low and bad. This is only because aluminium is so sensitive to turbulence. Uncontrolled transfer and handling of the liquid aluminium results in formation of double oxide defects known as bifilms. Bifilms are detrimental defects. They form porosity and deteriorate the properties. The detection and quantification of bifilms in liquid aluminium can be carried out by bifilm index measured in millimetres as an indication of melt cleanliness using Reduced Pressure Test (RPT). In this work, recycling efficiency and quality change of A356 alloy with various Ti additions have been investigated. The charge was recycled three times and change in bifilm index and bifilm number was evaluated. It was found that when high amount of Ti grain refiner was added, the melt quality was increased due to sedimentation of bifilms with Ti. When low amount of Ti is added, the melt quality was degraded.
