This paper presents the HDG learning algorithm, which uses a hierarchical decomposition of the state space to make learning to achieve goals more efficient with a small penalty in path quality. Special care must be taken when performing hierarchical planning and learning in stochastic domains, because macro-operators cannot be executed ballistically. The HDG algorithm, which is a descendent of ...

  Abstract   Background: The purpose of this study was to evaluate the significance of the Q   angle with respect to the patella position. We assess the correlation between the Q angles (calculated by clinical exam) in different positions and CT indices (with more   impression on TTTG).   Method: Atotal number of 68 knee joints of 50 cases entered the study. Clinical   examination was used to m...

This paper focuses on chemical characterization of ice-nucleating particles and the results from different sampling techniques are compared. The scientific results are in-teresting and the comparison of different techniques is necessary. The results from this paper are an important contribution to the fields of ice nucleation and aerosol chem-istry; however, I can only recommend this paper for ...

Globalization is not a rite of passage and culture appears to be the most neglected and underestimated source of challenge in global professional services. Academic research on national culture and cultural differences has identified dimensions with an effect on the functioning not only of societies and individuals, but also of organizations and project teams. Once cultural differences are reco...

The appropriateness of various numerical procedures for obtaining valid time-derivative data recently reported in the literature (Zernicke et a/., 1976: McLaughlin er al., 1977; Pezzack et u/., 1977) is discussed. A case for the use of quintic natural splines is presented. based on the smoothness of higher derivatives and flexibility in application. \‘ES; /\ . _J”P JGTc, SE=5 :;yz,s’sy = z7 ___...

We give the path model solution for the cluster algebra variables of the T system of type Ar with generic boundary conditions. The solutions are partition functions of (strongly) non-intersecting paths on weighted graphs. The graphs are the same as those constructed for the Q-system in our earlier work, and depend on the seed or initial data in terms of which the solutions are given. The weight...

‎We characterize the finite simple groups $L_2(q)$ by the group orders and the largest‎ ‎element orders‎, ‎where $q$ is a prime or $q=2^a$‎, ‎with $2^a+1$ or $2^a-1$ a prime‎.
