In this paper, we propose an automatic method for generating roads based on a weighted anisotropic shortest path algorithm. Given an input scene, we automatically create a path connecting an initial and a final point. The trajectory of the road minimizes a cost function that takes into account the different parameters of the scene including the slope of the terrain, natural obstacles such as ri...

This chapter introduces the computational infrastructure that is used to bridge the gap between results from sensorimotor processing and language. It consists of a system called Incremental Recruitment Language (IRL) that is able to configure a network of cognitive operations to achieve a particular communicative goal. IRL contains mechanisms for finding such networks, chunking subnetworks for ...

We propose a single-valued solution that extends both the consistent Shapley value of Maschler and Owen (1989) and Raiffa’s discrete bargaining solution to a large class of NTU games. Though not axiomatized, the solution is motivated via the Nash program. In this respect, we follow an approach that is similar to the one initiated by Hart and Mas-Collel (1996). JEL Classification: C71. Aspirant ...

We present a simple model for synthesis of butterfly wing patterns. The model simulates the formation of eyespots as are called the rounded circular arrangements which appear in many butterfly species. We illustrate our results with the examples of Diatheria clymena and Automeris io species.

Overhangs have been a major stumbling block in the context of terrain synthesis models. These models resort invariably to a heightfield paradigm, which immediately precludes the existence of any type of overhang. This article presents a new technique for the generation of surfaces, with the ability to model overhangs in a procedural way. This technique can be used generally to model landscape e...

The view of NLs as codes mediating a mapping between “expressions” and the world is abandoned to give way to a view where utterances are seen as actions aimed to locally and incrementally alter the affordances of the context. Such actions employ perceptual stimuli composed not only of “words” and “syntax” but also elements like visual marks, gestures, sounds, etc. Any such stimuli can participa...

BACKGROUND Emergency physicians often treat patients who require procedural sedation for the management of upper extremity fractures, dislocations, and abscesses (upper extremity emergencies). Unfortunately, procedural sedation is associated with several rare but potentially serious adverse effects and requires continuous hemodynamic monitoring and several dedicated staff members. The purpose o...

PURPOSE To evaluate the impact of pre-procedural coronary plaque composition assessed by virtual histology intravascular ultrasound (VH-IVUS) on late stent malapposition assessed by optical coherence tomography (OCT) following drug-eluting stent (DES) implantation. MATERIALS AND METHODS The study population consisted of 121 patients (121 lesions) who underwent both pre-procedural VH-IVUS and ...

AIMS The aim of this study was to perform quantitative analysis of the plaques of target lesions by integrated backscatter intravascular ultrasound (IB-IVUS) and to investigate the association between these data and the risk of post-procedural myocardial injury after stenting. METHODS AND RESULTS One hundred and fourteen consecutive patients who received elective stent implantations following...

A procedural pattern generation process, called multi-scale “assemblage” is introduced. An assemblage is defined as a multi-scale composition of “multi-variate” statistical figures, that can be kernel functions for defining noiselike texture basis functions, or that can be patterns for defining structured procedural textures. This paper presents two main contributions: 1) a new procedural rando...
