In this work we address the Single-Source Uncapacitated Minimum Cost Network Flow Problem with concave cost functions. This problem is NPhard, therefore we propose a hybrid heuristic to solve it. Our goal is not only to apply an Ant Colony Optimization (ACO) algorithm to such a problem, but also to provide an insight on the behaviour of the parameters in the performance of the algorithm. The pe...

Mesopotamia is the broad, flat alluvial plain between the Tigris and Euphrates Rivers in what is today Syria and Iraq (Fig. 1). Under the rule of Sargon of Akkad, the world’s first united empire was established in this region, linking the remote agricultural hinterlands of northern Mesopotamia with the complex city-states in the south. This united empire extended from the Persian Gulf to the he...

Abstract We herein propose an alternative model for deformation caused by eruption at Sakurajima, which has been previously interpreted as being due to a Mogi-type spherical point source beneath Minami-dake. On November 13, 2017, large explosion with plume height of 4200 m occurred During the 3 min following onset (November 22:07–22:10 (Japan standard time (UTC + 9); same hereinafter), phase 1,...

Following another person’s gaze in order to achieve joint attention is an important skill in human social interactions. This paper analyzes the gaze following problem and proposes a learning-based computational model for the emergence of gaze following skills in infants. The model acquires advanced gaze following skills by learning associations between caregiver head poses and positions in spac...

A lot of work has been done extracting depth from image sequences, and relatively less has been done using only single images. Very little has been done merging these together. This paper describes the fusing of depth estimation from two images, with monocular cues. The paper will provide an overview of the stereo algorithm, and the details of fusing the stereo range data with monocular image f...
