Interpreting archaeological boat material, the G1 boat of the Gokstad find

The cocktail boat.

We describe the inspiration, development, and deployment of a novel cocktail device modeled after a class of water-walking insects. Semi-aquatic insects like Microvelia and Velia evade predators by releasing a surfactant that quickly propels them across the water. We exploit an analogous propulsion mechanism in the design of an edible cocktail boat. We discuss how gradients in surface tension l...

Rocking the Boat: Damage to Eelgrass by Swinging Boat Moorings

Seagrass meadows commonly reside in shallow sheltered embayments typical of the locations that provide an attractive option for mooring boats. Given the potential for boat moorings to result in disturbance to the seabed due to repeated physical impact, these moorings may present a significant threat to seagrass meadows. The seagrass Zostera marina (known as eelgrass) is extensive across the nor...

Thinking with the Coleman Boat

Market Research in the Boat Tourism Segment

The purpose of this study was to determine whether there is a need for better tourism information on a portable media like a PDA or mobile phone. The market segment addressed in this market research was boat tourists in the Baltic Sea Region. Two parallel surveys were carried out; a quantitative survey with a sample of 665 respondents and a qualitative survey with 30 respondents. The results in...

Improvement and Validation of the BOAT Algorithm

The main objective of this paper is improving the BOAT classification algorithm and applying it in credit card big data analysis. Decision tree algorithm is a data analysis method for the classification which can be used to describe the extract important data class models or predict future data trends. The BOAT algorithm can reduce the data during reading and writing the operations, the improve...
