A PARALLEL ALGORITHM FOR ANALYZING CONNECTED COMPONENTS IN BINARY IMAGES
1992
In this paper, a parallel algorithm for analyzing connected components in binary images is described. It is based on the extension of the Cylindrical Algebraic Decomposition (CAD) to a two-dimensional (2D) discrete space. This extension allows us to find the number of connected components, to determine their connectivity degree, and to solve the visibility problem. The parallel implementation of the algorithm is outlined and its time/space complexity is given.
Soil Erosion as an Environmental Concern ... for Everyone?
2020
Nowadays, the scientific community is aware of the negative environmental impacts of soil erosion on ecosystem services. Soil erosion is one of the most important causes of land degradation because of its immediate influence of the most fertile topsoil parts. It is well-known that questions related to who, what, why, where and when soil erosion causes negative impacts must be considered by stakeholders and policymakers. However, why do the Sustainable Development Goals tell anything about soil erosion? In this keynote, we will try to show the importance to develop tools which can be used to assess soil erosion to obtain convincing results for stakeholders and policymakers. According to this…
W więzieniu widoczności medialnej. Rozważania o mikropolityce w "ponoptykonicznej rzeczywistości"
2017
W dobie telefonów komórkowych z dostępem do Internetu, wyposażonych w cyfrowe aparaty fotograficzne, „fotoreporterem” może zostać każdy. Dziś polityk nie tylko musi potrafić dobrze się zaprezentować, ale będąc ciągle narażonym na upublicznienie, kontrolować każdy swój gest i ważyć każde słowo. Każdy błąd czy gafa szybko może przerodzić się w poważny kryzys zagrażający wizerunkowi aktora politycznego. Na ciągłą widoczność narażone są nie tylko najważniejsze osoby w państwie, ale wręcz każdy. Co równie istotne, współczesna polityka oparta jest na ciągłej medialnej widoczności. Aktywna obecność na portalach społecznościowych staje się równie ważna, o ile nie ważniejsza od tego, kto i jak głoso…
3D part inspection path planning of a laser scanner with control on the uncertainty
2011
International audience; This article concerns the measurement process of mechanical parts using laser scanners. From the point of view of industrial applications, the objective is to guarantee the measurement accuracy during the scanning with regard to the geometrical product specifications. The proposed method can be summarized as follow: the first step consists of analyzing the interval of tolerance for the different specifications and to attribute to every geometrical entity a maximal uncertainty of measurement. This uncertainty depends on the angle of incidence between the laser plane and the scanned surface. In the second step, an approach based on the concept of visibility is used fro…
Can the Excluded Criticize? On the (Im)possibilities of Formulating and Understanding Critique
2021
If critique does not want to be more than just a ‘passion of the head’ it has to engage in dialogue with the worst-off in society. However, there are several mechanisms that hinder the excluded fro...
Towards Critical Research on Invisibility
2019
In this chapter, it will be asked how the struggle between visibilization and invisibilization engages in a struggle against social suffering.
On the Bride’s side? Fra politica della dislocazione ed etica del posizionamento
2016
This paper aims at critically exploring the network geographies underlying the production, distribution and consumption of the Italian docu-film "On the Bride’s side". Through a successful crowdfunding campaign and hundreds of screenings throughout Europe, the docu- film has given rise to a wide diasporic public sphere. It is here that mainstream practices and alternative imaginations combine each other and unveil the complex and contested production of the cultural field
Distributed Leadership and the Visibility/Invisibility Paradox in On-line Communities
2011
This paper analyzes the role of distributed leadership in three on-line communities, reflecting on an observed visibility/invisibility paradox in leadership within these communities. Leaders who downplay their seniority and assume a degree of invisibility, allocating discretionary powers to subordinate levels in an organizational hierarchy, may facilitate the emergence of distributed leadership. Yet, simultaneously, leader-led relations are enabled by high leadership visibility. This paradox—that leaders need to be both highly visible and also invisible, or hands-off, when the occasion requires it—was derived from prior research into e-learning communities and tested in the analysis of disc…
