We investigate whether there were common causes for the withdrawal from the regional aircraft market of three established manufacturers (BAE Systems, Fokker and Saab), while competitors thrived. We focus on the markets for 50and 100-seat aircraft. One cause concerning the 50-seat market was the introduction of a new class of aircraft, the regional jet, which pushed the less successful turboprop...

Introduction: Diffusion tensor imaging (DTI) is a non-invasive MR imaging technique that can be used to probe in-vivo the microstructural properties of brain tissue [1]. Accurate inter-subject spatial normalization of DTI data is crucial for voxel-based comparisons of neuronal structural integrity [2] and brain connectivity [3] across populations, as well as for the development of a white matte...

performance analysis of jet engines in various environmental conditions is important and is the first step in the design of such engines. in this paper, the performance of a typical turboprop engine was modeled in the commercial software gasturb10 and the obtained results are validated at three flight regimes take off, military and 100% normal using engine test results. performance analysis of ...
