Botanical Supplements: Weeding Out the Health Risks

An important challenge in the analysis of mechanochemical coupling in molecular motors is to identify residues that dictate the tight coupling between the chemical site and distant structural rearrangements. In this work, a systematic attempt is made to tackle this issue for the conventional myosin. By judiciously combining a range of computational techniques with different approximations and s...

Data Weeding Techniques Applied to Roget's Thesaurus

It can be difficult to automatically generate “nice” graphical representations for concept lattices from lexical databases, such as Roget’s Thesaurus, because the data sources tend to be large and complex. This paper discusses a variety of “data weeding” techniques that can be applied in order to reduce the size of a concept lattice, first, in general and then with respect to Roget’s Thesaurus....

Weeding the Reference Collection: a Review of the Literature

the actual mechanics of performing this activity vary widely and is the cause of much concern in libraries. Furthermore, the actual decision process for selecting an item to be culled from the primary collection is not fixed, and varies according to the type of library under study and/or to the mandate of the library. Thus, the approach to weeding taken by a small public library has an outcome ...

An Autonomous Weeding Robot for Organic Farming

The objective of this research is the replacement of hand weeding in organic farming by a device working autonomously at field level. The autonomous weeding robot was designed using a structured design approach, giving a good overview of the total design. A vehicle was developed with a diesel engine, hydraulic transmission, four-wheel drive and four-wheel steering. The available power and the s...
