In automated negotiation systems consisting of self-interested agents, contracts have traditionally been binding. Leveled commitment contracts | i.e. contracts where each party can decommit by paying a predetermined penalty | were recently shown to improve Pareto ef-ciency even if agents rationally decommit in Nash equilibrium using innated thresholds on how good their outside ooers must be bef...

We investigate two types of graph layouts, track layouts and layered path decompositions, and the relations between their associated parameters track-number and layered pathwidth. We use these two types of layouts to characterize leveled planar graphs, the graphs with planar layered drawings with no dummy vertices. It follows from the known NP-completeness of leveled planarity that track-number...

We analyzed the trends in the age-standardized incidence rates of 10 460 cases of primary intracranial tumors diagnosed during 1975 and 2004, Osaka, Japan using the Joinpoint regression analysis. During the period 1975–2004, the age-standardized incidence rates of total intracranial tumors increased until 1987 at 3.1% per year and then decreased significantly at 21.8% per year. The time trends ...

Highly integrated and extended application of product model based engineering using product lifecycle management systems is the most important recent achievement in computer aided engineering. Continuous development of products and their variants placed management of changes of engineering objects during development of product in the centre of investigations in product modeling. The authors joi...

We analyzed the trends in the age-standardized incidence rates of 10,460 cases of primary intracranial tumors diagnosed during 1975 and 2004, Osaka, Japan using the Joinpoint regression analysis. During the period 1975-2004, the age-standardized incidence rates of total intracranial tumors increased until 1987 at 3.1% per year and then decreased significantly at -1.8% per year. The time trends ...

one of the basic adjustments in application of agricultural implements, particularly tillage tools, is their work in a leveled state while in operation. throughout the ongoing research, and by application of electronic and hydraulic circuits, an intelligent system was designed, developed and evaluated. the device is expected to perform the plow longitudinal as well as lateral adjustments at the...

Generational garbage collection (GGC) is one of the most popular garbage collection techniques. GGC gains a performance advantage by performing minor collections on the younger objects in the heap, reducing the number of major collections of the whole heap. A promotion policy determines when an object moves from the younger generation to the older. The design of GGC has been justified by the pl...
