A method for efficient measurement-based COTS assessment and selection - Method description and evaluation results

The use of Commercial-off-the-Shelf (COTS) software has become more and more important in state-of-the-art and state-of-the-practice software and system development. The use of COTS software promises faster time-to-market, reduced development cost, increased productivity, and the possibility for companies to focus on their own core competencies. At the same time COTS software raises risks such as

Planar droplets sizing of a hollow-cone spray using SLIPI-LIF/Mie

In this work, we report an original experimental approach for measuring the two-dimensional distribution of the droplets Sauter Mean Diameter (SMD) using the SLIPI-LIF/Mie technique. A hollow-cone spray is formed by continuously injecting water mixed with a non-toxic fluorescing dye at 20 bars injection pressure. The spray is illuminated using a continuous wave laser. The illumination wavelength (

Load Modulation for Damping of Electro-Mechanical Oscillations

Today it is feasible for utilities to control selected customer loads in a nondisturbing fashion. This is comparable to load shedding, but has a wider area of application. This paper focuses on direct load control or modulation for power system damping and is based on a field test of on-off control and modal analysis of differential-algebraic equation models of three test systems. Real power load
