A novel mode control device is described, comprising a point-load mode scrambler in tandem with a mode filter. The device may be tuned to ensure compliance of fibre test equipment with new link performance standards. Improvement in the reproducibility of insertion loss measurements on concatenated fibres is demonstrated. [ABSTRACT FROM AUTHOR]

Entrepreneurial planning and control systems have been designed and developed specifically for startup environment to improve the odds of survival for a startup and to encourage entrepreneurial managers and teams to formulate and implement strategies. They are based on years of research, testing, and practical application with startups, incubators, business development organisations, and investors in the U.S. and New Zealand. These systems are designed specifically to help new and growing companies do a number of things. The three systems that form the entrepreneurial planning and control system are action controls, strategy controls, and performance controls. [ABSTRACT FROM AUTHOR]

The construction and performance measurement of a quasi-optical Fresnel rhomb for millimetre wavelengths is described. The Fresnel rhomb was found to operate successfully over W-band with an efficiency ranging from 85 to 95% as the frequency increased from 85 to 99 GHz. Thus, the device offers a wideband performance quarter-wave plate, suitable for quasi-optical systems at millimetre wavelengths. [ABSTRACT FROM AUTHOR]
