Inspired by Stillman Drake’s definition of G&lean Units as those for which & = (g)g where g is any finite, constant acceleration measured in units of L and T, we construct a lcinematical dimensional analysis based only on two universal, dimensionless constants. For the linear relation between L and T we use Einsteinian Units 6 = (1)~. For orbiting masses negligible compared to some mass unit M,...

Existing studies on data acquisition in vehicular networks often take the mobile vehicular nodes as data carriers. However, their autonomous movements, limited resources and security risks impact the quality of services. In this article, we propose a data acquisition model using stable matching of bipartite graph in cooperative vehicle-infrastructure systems, namely, DAS. Contents are distribut...

This paper deals with a strategic issue in the stable marriage model with complete preference lists (i.e., a preference list of an agent is a permutation of all the members of the opposite sex). Given complete preference lists of nmen over n women, and a marriage μ, we consider the problem for finding preference lists of n women over n men such that the men-proposing deferred acceptance algorit...

Many discrete event systems (DESs) such as manufacturing systems, database management systems, communication networks, tra c systems, etc., can be modeled as input-output discrete event systems (I/O DESs). In this paper we formulate and study the problem of stable realization of such systems in the logical setting. Given an input and an output language describing the sequences of events that oc...

The stable marriage problem is that of matching n men and n women, each of whom has ranked the members of the opposite sex in order of preference, so that no unmatched couple both prefer each other to their partners under the matching. At least one stable matching exists for every stable marriage instance, and efficient algorithms for finding such a matching are well known. The stable roommates...

Eastern boundary currents are often described as 'wasp-waist' ecosystems in which one or few mid-level forage species support a high diversity of larger predators that are highly susceptible to fluctuations in prey biomass. The assumption of wasp-waist control has not been empirically tested in all such ecosystems. This study used stable isotope analysis to test the hypothesis of wasp-waist con...

The general theoretical issues of set phrases have yet to be studied at the level requirements modern linguistics, position such language units has not been clearly defined, and their boundaries with other remain uncertain. Issues as nature phrases, formation, types, attitude linguistic units, especially words sentences, features development, still need addressed in linguistics. article's autho...

Two experiments with rats examined the dynamics of well-learned response sequences when reinforcement contingencies were changed. Both experiments contained four phases, each of which reinforced a 2-response sequence of lever presses until responding was stable. The contingencies then were shifted to a new reinforced sequence until responding was again stable. Extinction-induced resurgence of p...
