Optimizing the Product Derivation Process [PDF]
2011 15th International Software Product Line Conference, 2011 Feature modeling is widely used in software product-line engineering to capture the commonalities and variabilities within an application domain. As feature models evolve, they can become very complex with respect to the number of features and the dependencies among them, which can cause the product derivation based on feature selection to become quite

Discrete Applied Mathematics, 1980 AbstractIt is often desirable to perform a “sensitivity analysis” by perturbing the data given with a problem. Motivated by serial and nonserial dynamic programming, we define a variety of sensitivity analysis problems, produce algorithms, and obtain lower bound results.

Review of Acoustic Sources Alternatives to a Dodecahedron Speaker
Applied Sciences, 2019 An omnidirectional source is required in many acoustic measurements. Commonly a dodecahedron speaker is used but due to various factors (e.g., high cost, transportation difficulties) other acoustic sources are sometimes preferred. In this review, fifteen
