The quality of manufactured products is characterized by many controllable quality factors. These factors should be optimized to reach high quality products. In this paper we try to find the controllable factors levels with minimum deviation from the target and with a least variation. To solve the problem a simple aggregation function is used to aggregate the multiple responses functions then a...

The aeroheating environment of the Mars Reconnaissance Orbiter (MRO) has been analyzed using the direct simulation Monte Carlo and free-molecular techniques. The results of these analyses were used to develop an aeroheating database to be used for the preflight planning and the in-flight operations support for the aerobraking phase of the MRO mission. The aeroheating predictions calculated for ...

The structure evolutions of Al83Ni10Ce5Si2, Al83Ni10Ce7, Al85Ni10Ce5, Al87Ni7Nd6 and Al87Ni5Co2Nd6 metallic glasses have been studied in detail. The studies establish a relation between the amount of medium range order (MRO) and crystallization mode. An increased amount of MRO suppresses the precipitation of primary fcc-Al and transforms the crystallization mode from a primary crystallization (...

We present a semantic-based ontology mapping framework that offers instance transformation and discovery of new mapping using reasoning. Our framework comprises an expressive OWL-Full Mapping Representation Ontology (MRO) and a mapping translation method. Ontology mappings are represented in terms of an instantiation of the MRO. We define formal semantics for our ontology mapping representation...

We estimate spatial gradients in the ionosphere using the Global Positioning System (GPS) and GLONASS (Russian global navigation system) observations, utilising data from multiple GPS stations in the vicinity of Murchison Radio-astronomy Observatory (MRO). In previous work the ionosphere was characterised using a single-station to model the ionosphere as a single layer of fixed height and this ...

In this paper, we examine how fundamental changes that are taking place in the aviation industry are affecting strategies for managing service parts that are needed to support maintenance and repair operations (MRO). We present observations and recommendations based on the results of an empirical research project initiated by a large European airframe OEM that facilitates the sharing of part co...

The increasing need for Maintenance Repair Overhaul organisations (MROs) to meet customers’ demands in quality and reduced lead times is key to its survival within the Aviation industry. Furthermore, with the unpredictability in the global market and difficulties with forecasting characteristic of the MRO industry there is an increased need for the re-evaluation of the operation models of organ...

There are many real problems in which multiple responses should be optimized simultaneously by setting of process variables. One of the common approaches for optimization of multi-response problems is desirability function. In most real cases, there is a correlation structure between responses so ignoring the correlation may lead to mistake results. Hence, in this paper a robust approach based ...
