Mowing a lawn can be a difficult and tedious chore. The goal of this paper is to introduce the idea of using the visual property of texture to design an autonomous lawnmower robot that mows a lawn similar to how a human would (in some type of pattern.) Previous autonomous lawnmowers that have been designed, the LawnNibbler and LawnShark for example, rely on the principle of randomness to mow in...

The standard initial treatment of lawn mower injuries to the foot consists of prompt administration of parenteral antibiotics, debridement of devitalized tissue, irrigation, repair of traumatized vascular structures, and stabilization of osseous fractures. The primary closure of these wounds at the initial operation is a controversial concept. The authors performed a retrospective study of 9 la...

This paper presents an evolutionary synthesis of feature extraction programs for object recognition. The evolutionary synthesis method employed is based on linear genetic programming which is combined with redundancy-removed recombination. The evolutionary synthesis can automatically construct feature extraction programs for a given object recognition problem, without any domain-specific knowle...

Chlamydomonas reinhardtii, a unicellular green alga, has been used in bioassay detection of a variety of toxic compounds such as pesticides and toxic metals, but mainly using liquid culture systems. In this study, an algal lawn-agar system for semi-quantitative bioassay of herbicidal activities has been developed. Sixteen different herbicides belonging to 11 different categories were applied to...
