Abstract

In this work, simulation techniques have been implemented to study the sound fields of a multi-configurable performance enclosure by creating computer acoustic 3D-models for each room configuration. The digital models have been tuned by means of an iterative fitting procedure that uses the reverberation times measured on site for unoccupied conditions with the orchestra shell on the stage. The initial virtual acoustic model is validated by comparing the other monaural and binaural acoustic parameters measured in the room in terms of their perception differential threshold. The procedure is applied to the Maestranza Theatre of Seville, built for the Universal Exhibition in 1992. The spatial distribution of the acoustic parameters in the audience area of the venue by measured parameters and simulation mappings enables the establishment of three zones of acoustic comfort, and are corroborated by the values of the Ando-Beranek function which provide a global quality coefficient of each zone.

Abstract

The paper presents selected results of the work carried out at the Air Force Institute of Technology (AFIT) in the scope of computer diagnostic tests of the SWPL-1 Cyklop helmet mounted flight parameters display system. This system has been designed in such a way that it warns the pilot of dangerous situations occurring on board the helicopter and threatening the flight safety (WARN) or faults (FAIL), which inform about a failure in given on-board equipment. The SWPL-1 system has been awarded the Prize of the President of the Republic of Poland during the 17. International Defense Industry Exhibition in Kielce.

Abstract

This study attempts to examine the differences in the collaborative activities between the Turkish contracting firms that are listed as the “Top 225 International Contractors” by Engineering News Record (ENR), according to their international revenues, and other large contracting firms that are not on this list. For this purpose, 30 large-scale Turkish general contracting firms, including 15 listed by the ENR, have been examined in terms of their collaborations during the innovation process as well as the levels of significance for the sources of information that serve as the means of “sources of innovation”. Results show some remarkable differences between the top-listed firms and other large-scale contracting companies. The levels of importance indicated for the collaborations made with “universities and research institutions” and the sources of information “conferences, fairs and exhibitions” and “scientific/ technical publications” show remarkable differences between the two groups of companies. Contractors who are not ENR listed are more active in making collaborations. While the number of collaborations is increasing in the timeline, both groups of contractors indicate the most important collaborations as “consultants, private R&D institutions” and “suppliers”. Findings also show a decreasing interest against collaborations with universities. Finally, findings of the research are discussed in the context of innovation, expecting to contribute to international contracting firms in evaluating their innovation approaches to their competitive advantage.
