Transnational entrepreneurs are often represented as active agents capable of mobilizing resources situated in different countries to develop new businesses. However, restrictive migration regimes limit the possibilities individuals become entrepreneurs. Based on ethnographic research Barcelona, Spain, this article argues that, a context unequal access formal resources, resorting informality is...

Abstract The meridional overturning circulation consists of an upper and lower cell. Southern Ocean Biogeochemical Divide (SOBD) is the boundary between two cells in surface Ocean, but its location poorly constrained. Localizing SOBD important because biological nutrient utilization north south have fundamentally different consequences for global ocean primary production carbon sequestration. H...

In this article, we propose a new method for localizing optic disc in retinal images. Localizing the optic disc and its center is the first step of most vessel segmentation, disease diagnostic, and retinal recognition algorithms. We use optic disc of the first four retinal images in DRIVE dataset to extract the histograms of each color component. Then, we calculate the average of histograms for...

We investigate the fault-tolerance of distributed algorithms in asynchronous message passing systems with undetectable process failures. We introduce failure locality as a measure of the fault-tolerance of distributed algorithms. This measure captures the general idea of allowing part of a system to continue to function despite the failure of other parts of the system. We concentrate on two pro...

A bsfracf-Ultrasonic holographic imaging holds the potential for recognizing object contours in two-dimensional or three-dimensional space. The theory of both the monofrequency and multifrequency modes of the method, as suitable for the requirements of object recognition in robot assembly tasks, is described. The theory was implemented experimentally. Results obtained show that the monofrequenc...

In this chapter, we present a weakly-supervised approach that discovers the spatial extent of relative attributes, given only pairs of ordered images. In contrast to traditional approaches that use global appearance features or rely on keypoint detectors, our goal is to automatically discover the image regions that are relevant to the attribute, even when the attribute’s appearance changes dras...

Humans can e ectively navigate through large search spaces, enabling them to solve problems with daunting complexity. This is largely due to an ability to successfully distinguish between relevant and irrelevant actions (moves). In this paper we present a new single-agent search pruning technique that is based on a move's in uence. The in uence measure is a crude form of relevance in that it is...

In clause (i) of Lemma 2.1 of [1] it is claimed that in BST we can show the existence of ω as the least inductive set. BST contains the axiom of Infinity saying that “there is an inductive set”. However one cannot see how to prove the existence of a least inductive set without either ∈-induction or at least Π1-Separation, both of which are not included in BST. The simplest way to correct this f...
