Studies were designed to evaluate the effectiveness of pulsed modulated UV light waveforms for killing bacteria. Exposure of five strains of bacteria to the modulated information encoded in the light decreased the colony population from a confluent lawn to less than 20 colonies. However, approximately 2,000 colonies survived treatment with the same intensity and time of exposure to UV light lac...
We present the case of a 72-year-old man with hemoptysis after a thoracic projectile injury, which occurred while mowing the lawn. Chest radiograph followed by a computed tomography angiogram revealed a metallic foreign body in the right middle lobe of the lung. The patient underwent a right anterolateral thoracotomy where the object was successfully retrieved. The patient had an uneventful pos...
This study is about the manufacturing of a personified automatic robotic lawn mower with image recognition. The system structure that platform above crawler tracks combined mower, steering motor, slide rail, and webcam to achieve purpose personification. Crawler strong grip good ability adapt terrain are selected as moving vehicle simulate human feet. In addition, mechanism designed left right ...
We describe a project in which a game of lawn bowls was recreated using Distributed Interactive Audio Devices (DIADs), to create an interactive musical experience in the form of a game. This paper details the design of the underlying digital music system, some of the compositional and design considerations, and the technical challenges involved. We discuss future directions for our system and c...

This paper describes the development of a robotic heavy duty lawn mower provided with a rich set of sensors which initially provide tele-operation mode capabilities but will support extension towards full autonomy via an intermediate mode termed teleautonomous to reflect a multilevel control structure which permits graceful withdrawal of human guidance as the development proceeds.
Although the principles of landscape ecology are increasingly extended to include riverine landscapes, explicit applications are few. We investigated associations between patch heterogeneity and riparian ant assemblages at 12 riverine landscapes of the Scioto River, Ohio, USA, that represent urban/developed, agricultural, and mixed (primarily forested, but also wetland, grassland/fallow, and ex...
Green leaf volatiles (GLVs) are a class of woundinduced volatile organic compounds emitted by several plant species. Turf grasses emit a complex profile of GLVs upon mowing, as evidenced by the “freshly cut grass” smell, some of which are readily oxidized in the atmosphere to contribute to secondary organic aerosol (SOA). The contribution of lawn-mowing-induced SOA production may be especially ...
