MPEG, the Mowing Picture Experts Group, is a popular compression standard used in many multimedia applications. I n video distribution systems, a CBR communications channel is often shared among several VBR MPEG video streams. Since there are fluctuations of data rates an video streams, t ra f ic congestion may occur and video quality may he aflected. W e propose a frame-skipping aggregation te...

OVERSEEDING: WHICH GRASSES ARE BEST 1971 overseeding results in south Florida. A. E. Dudeck andE. O. Burt. Florida Turf. 4 (5):3-6. (from the University of Florida Agricultural Research Center, Fort Lauderdale, Fla. 33314). The objective of this investigation was to evaluate monostands and polystands of various cool season turfgrasses for use in overseeding dormant bermudagrass putting greens u...

The industry trend to golf putting greens which produce greater ball-roll distances has led to development of high density creeping bentgrass (Agrostis palustris, Huds.) cultivars that tolerate very low mowing heights. These cultivars also have a finer leaf texture and improved competitiveness with the invasive weed, annual bluegrass (Poa annua L.). In this multi-year field study, newer cultiva...

The aim of the article is to define hyssop ( Hyssopus officinalis ) ‘Markiz’ cultivar capacity parameters aimed at recultivating degraded soils, alkali sloping lands, local landscaping technologically polluted areas, which will promote improvement anthropogenically transformed ecosystems. To implement such practical measures comprehensive approach should be used while selecting agronomic for gr...

Clothoids are very useful for smoothing the motion of a mobile robot mowing along a trajectory. This paper addresses the problem of smoothing the mobile robot motions when cusps, i e . , changes of motion direction along the trajectory, are imposed. We pinpoint some special curves (that we call uanticlothoids”) and we discuss how they can be used together with clothoids in order to smooth a pre...
