The spectral characteristics of laboratory turbulence obtained from the Shack-Hartmann wavefront sensor focal spot coordinates dynamics are presented. The limits of applicability of a fast adaptive optical system in a real atmosphere are determined.
In the early 2000s, the UK automotive industry was in a state of decline. Factory closures were commonplace, innovation levels modest, the supply chain shrinking, and environmental regulations seen as a threat. However, the industry has undergone a renaissance in the past decade, with UK low-carbon automotive investments of around £40 billion, increasing sector turnover, rising vehicle production volumes, and major OEM capacity expansions. This article sought to identify and understand the causal relationships between the UK's low-carbon policies and automotive industry investments via a triangulated methodology comprising an industry-wide survey, interviews of senior industry executives, extensive secondary research, construction of an investment database, and detailed policy analyses. It is concluded from the research that the strong co-operation between government and industry has proved vital to weathering the economic crisis and maintaining growth. Also, introduction of strong, cumulative industrial policies, and environmental regulations, together with funding programmes emerged as powerful driving forces for continued investment. Nevertheless, challenges remain and there is no room for complacency. Continued dialogue, support, and action are required to ensure that UK industry can deliver on low-carbon targets and build a sustainable industry and vehicle fleet.
Lossless audio technology is a kind of important audio coding technology which is used to archive digital audio data and encode high quality audio.Lossless audio codec system with lossy codec is described.It includes lossless extension through lossy coding residual and independent lossless codec.Channel decorrelation,in-teger lifting wavelet,linear prediction,residuals handling and arithmetic entropy coding are adopted.In very com-plex conditions,the compression performance is achieved to internation mainstream lossless audio coding technolgy.
