Ascending and Descending Conditional Independence Relations
We explore the conditional probabilistic independences of systems of random variables (I; JjK), to read \I is conditionally independent of J given K", which are ascending (I; JjK)) (I; JjK L) or descending (I; JjK L)) (I; JjK). The resulting abstract independence structures can be equivalently described by weak families of connected sets. Using, in addition, probabilistic representations of mat...
متن کاملAscending and Descending Walking Recognition using Smartphone
In the recent decades, activity recognition for human behavior monitoring has been one of the major interesting research subjects. This paper investigates fractal dimension (FD) as an effective feature for human activity recognition. The target activities are descending and ascending stairs, which are performed by six male participants. To testify the validity of feature, the classification met...
متن کاملPermutations with Ascending and Descending Blocks
We investigate permutations in terms of their cycle structure and descent set. To do this, we generalize the classical bijection of Gessel and Reutenauer to deal with permutations that have some ascending and some descending blocks. We then provide the first bijective proofs of some known results. We also solve some problems posed in [4] by Eriksen, Freij, and Wästlund, who study derangements t...
متن کاملDerangements with Ascending and Descending Blocks
We continue the work of Eriksen, Freij, and Wästlund [3], who study derangements that descend in blocks of prescribed lengths. We generalize their work to derangements that ascend in some blocks and descend in others. In particular, we obtain a generating function for the derangements that ascend in blocks of prescribed lengths, thus solving a problem posed in [3]. We also work towards a combin...
متن کاملValue Construction and Bidding Behavior in Descending and Ascending Auctions
We report two experiments examining how a set of motivational, cognitive and situational factors drives consumers’ value construction and bidding in auctions involving real products. A motivational antecedent, bidder goals (winning the item versus acquiring it at a price consistent with their value) is examined along with two cognitive factors (a) value precision (operationally, the width of a ...
