German Institute of Food Technologies The division has its own research projects planned for 2013. The quality of food is determined by their structure. Therefore, an optimization of food structures leads an improvement of long-term quality of food. Based on test on structure generation and the interdependency with the quality of food the DIL tries to increase the shelf-life of products. When the Bio-Economy division was founded in 2012, it was accompanied by an extensive realignment and expansion of the research platforms. As a result, meat technology was removed from the Process Technology business division, the biotechnology focus was placed on enzyme and raw material
Slowly varying envelope approximation Slowly varying envelope approximation In physics, the slowly varying envelope approximation (SVEA, sometimes also called slowly varying amplitude approximation or SVAA) is the assumption that the envelope of a forward-travelling wave pulse varies slowly in time and space compared to a period or wavelength. This requires the spectrum of the signal to be narrow-banded—hence it also referred to as the narrow-band approximation. The slowly varying envelope approximation is often used because the resulting equations are in many cases easier to solve than the original equations, reducing the order of—all or some of—the highest-order partial derivatives. But the validity of the
