Bucket increasing trees are multilabelled generalizations of trees, where each non-leaf node carries b labels, with b≥1 a fixed integer. We provide fundamental result, giving complete characterization all families bucket that can be generated by tree evolution process. also several equivalent properties, complementing and extending earlier results for ordinary to trees. Additionally, we state s...

AxialGen is a research prototype for automatically generating the axial map, which consists of the least number of the longest visibility lines (or axial lines) for representing individual linearly stretched parts of open space of an urban environment. Open space is the space between closed spaces such as buildings and street blocks. This paper aims to provide an accessible guide to software Ax...

Problem urgency. To improve the efficiency of road construction machines, especially in high altitude conditions, has been proposed a new design bulldozer-loader with transforming working equipment. Purpose. Methodology development to determine mass body, i.e. bucket, excluding material that may be bucket. Methods. Analyzed one main elements body - Further, using formulas for determining volume...

a r t i c l e i n f o a b s t r a c t Donations in-kind can be a mixed blessing for charities, who are often more adept at solicitation than resale. Many organizations rely on raffles to turn donations into cash, but auctions are also common. Theory predicts that all-pay mechanisms should produce more revenue than winner-pay mechanisms, but the empirical literature is thin and inconclusive. Dra...

Workers in a bucket brigade production system perform unproductive travel when they walk to get more work from their colleagues. We introduce a new design of bucket brigades to reduce unproductive travel. Under the new design, each worker works on one side of an aisle when he proceeds in one direction and works on the other side when he proceeds in the reverse direction. We propose simple rules...

The increased risk to the safety of excavator personnel and difficulty in training them, combined with a manpower shortage, have led an demand for machine automation. This study applies long short-term memory algorithm automating bucket-tip trajectory planning AI system. Unlike other autonomous excavation techniques, proposed approach this performs bucket-trajectory without prior knowledge nonl...
