Fuzzy Membership Function Initial Values: Comparing Initialization Methods That Expedite Convergence
… to converge to a stable membership value in the shortest time possible. The paper compares three initialization methods, Random, Midpoint and Random Proportional, to determine which method optimizes convergence. The comparison experiments suggest the use of the Random Proportional method.

The impact of grape clone, yeast strain and protein on sparkling wine quality
… the foaming properties. The longest elapsed time for foam dissipation was observed in the control treatment where bentonite was not used to strip protein and the shortest time was observed in the treatment where bentonite was used to remove grape and yeast proteins. In Riesling sparkling …

Ultra-high-temperature processed and conventionally processed milk in the preparation of instant pudding
… with HTST milk, warm milk, and longer elapsed time. The combination of cold milk and shorter time was least viscous. Gel strength of refrigerated pudding was greater for HTST milk, cold HTST, and longer time. Nonrefrigerated pudding was firmer for HTST milk and cold milk. Shortest time resulted …

Least Cost Path Modeling Between Inka and Amazon Civilizations
… between a start and end point, often in terms of shortest time or least amount of energy. The approach is often applied in archaeology to estimate locations of sites, and routes between them. We applied LCPA to estimate how sites in the Andes in the eastern portion of the Inka empire may have …

Navigation of a high velocity tele-operated ground vehicle through an obstacle rich environment
… These resolutions, one meter, half meter, and centimeter scale, were selected to be representative of what might be available in real situations. Subjects controlled the vehicle using a joystick, with reference to the a priori image and a real-time video image from the vehicle. The subjects' times …
