13 Knowledge about how many sh that have been killed due to bycatch is an important 14 aspect of ensuring a sustainable ecosystem and shery. We introduce a Bayesian spatio15 temporal prediction method for historical bycatch that incorporates two sources of available 16 data sets, shery data and survey data. The model used assumes that occurrence of bycatch 17 can be described as a log-linear co...

We present a new way of analyzing Contraction Hierarchies (CH), a widely used speed-up technique for shortest path computations in road networks. In previous work, preprocessing and query times of deterministically constructed CH on road networks with n nodes were shown to be polynomial in n as well as the highway dimension h of the network and its diameter D. While h is conjectured to be polyl...

The Traveler’s Problem (TP) entails determining the maximum distance that can be traversed along a road, given the locations and room rates of inns along that road, and given the constraints of maximum distance per day and limited budget available for overnight stays at inns. An OP(n 3 5_ (log n) 3 1_ ) time algorithm is presented for the TP. An OP(n 3 5_ (log n) 3 4_ )-time algorithm for compu...

Background and aims: Although accident is the secondary cause of mortality in Iran, information on the occurrence and mortality are not wholly understood. The study aimed to explore seasonal occurrence and mortality pattern of traffic accidents in Isfahan population, Iran. Methods: This study was a cross-sectional. The data on traffic accidents of Isfahan Province was extracted from the Minist...

This paper investigates a zero-sum game played on a weighted connected graph G between two players, the tree player and the edge player. At each play, the tree player chooses a spanning tree T and the edge player chooses an edge e. The payoo to the edge player is cost(T ; e), deened as follows: If e lies in the tree T then cost(T ; e) = 0; if e does not lie in the tree then cost(T ; e) = cycle(...

ABSTRACT Pope & Talbot Ltd., Arrow Lakes Timber Division, Nakusp, B.C. having no alternative options constructed a forest road with adverse haul grades up to 16%, to access a harvesting area. The company did not know the exact limitations of the adverse haul grade, but it did plan to use highway sized loads on this off-highway haul, thus sacrificing some productivity. When the road was complete...

The Reciprocal-Wedge Transform (RWT) is presented as an alternative to the log-polar transform which has been a popular model for space-variant sensing in computer vision. The log-polar transform provides efficient data reduction. It simplifies the centric rotational and scaling image transformations. However, it adversely complicates the linear features and translational transformations. The R...
