Wild hummingbirds require a consistent view of landmarks to pinpoint a goal location

Ordering Landmarks in a View

Angular measures to point landmarks such as mountain peaks can be used to navigate through large, unstructured environments if the landmarks have been matched to a map and their left to right order in the view is known. This paper addresses the problem of ordering those landmarks. Experiments run in simulation show that simple geometric properties can often be used to order landmarks, avoiding ...

from linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar

chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...

From Multiple Images to a Consistent View

Landmarks Constellation Based Position Estimation for Spacecraft Pinpoint Landing

This paper presents a vision-based approach to estimate the absolute position of a planetary lander during the last stages of the descent. The approach relies on the matching of landmarks detected in the descent imagery with landmarks previously detected in orbiter images. The matching process must be robust with respect to scale and radiometry differences in the image data: it mainly relies on...

A Solution to View Management to Build a Data Warehouse

Several techniques exist to select and materialize a proper set of data in a suitable structure that manage the queries submitted to the online analytical processing systems. These techniques are called view management techniques, which consist of three research areas: 1) view selection to materialize, 2) query processing and rewriting using the materialized views, and 3) maintaining materializ...
