Jews under Islam in early modern Morocco in travel chronicles
2020
This paper addresses the relationship between the ideological and legal structures that discriminated against Jews in early modern Morocco and its reflection in social practices. The study shows th...
The development and validation of the Business Cultural Intelligence Quotient
2016
Purpose– The purpose of this paper is to present a new instrument for measuring cultural intelligence in the business context (BCIQ).Design/methodology/approach– The paper describes the process of the conceptualization of the model and the development of the instrument, the sample, as well as the validation of the instrument. Directions on the use of the instrument and future research are discussed.Findings– The instrument shows good psychometric properties and good predictive power and outperforms other publicly available CQ measures on a number of dimensions.Originality/value– The unique features and advantages of the present instrument are as follows: first, a refined factor structure co…
Virtual Acoustic Rendering in Old Spaces: Application to an Early-Modern Theatre in València, “L’Olivera”
2018
The application of the VR to the renderization of ancient and lost buildings is one important topic in the cultural heritage field nowadays. Moreover, the addition of other senses apart from the graphical view, increases the sensation of immersion in a virtual application. The aim of this paper is to show the work on a virtual acoustic system, based on Unity, FMOD and Csound. This system has been implemented to render binaural auralizations and has been applied to the renderization of an old and lost theatre in Valencia (Spain). This theatre was firstly build in the 16th century, and rebuilt several times until the 18th century. It has been modelled from ancient documents. The auralization …
Definition of a Model-Based Detector of Curvilinear Regions
2007
This paper describes a new approach for detection of curvilinear regions. These features detection can be useful for any matching based algorithm such as stereoscopic vision. Our detector is based on curvilinear structure model, defined observing the real world. Then, we propose a multi-scale search algorithm of curvilinear regions and we report some preliminary results.
geomIO: An Open‐Source MATLAB Toolbox to Create the Initial Configuration of 2‐D/3‐D Thermo‐Mechanical Simulations From 2‐D Vector Drawings
2019
Creating the initial geometry and temperature configuration of 3D numerical simulations is a challenging task. Professional tools are expensive. They often have a steep learning curve and do mostly not interface with the numerical simulation software used by the geodynamics and tectonics academic community. There, we developed geomIO (geometry Input/Output), a MATLAB toolbox to create the initial configuration of geological models regarding model geometry and temperature structure. geomIO allows users to create a geo-referenced 3D volume by drawing multiple 2D cross-sections in a standard vector graphics editor. The volume is then used to assign material properties and set up initial temper…
Exudate-based diabetic macular edema detection in fundus images using publicly available datasets
2010
International audience; Diabetic macular edema (DME) is a common vision threatening complication of diabetic retinopathy. In a large scale screening environment DME can be assessed by detecting exudates (a type of bright lesions) in fundus images. In this work, we introduce a new methodology for diagnosis of DME using a novel set of features based on colour, wavelet decomposition and automatic lesion segmentation. These features are employed to train a classifier able to automatically diagnose DME through the presence of exudation. We present a new publicly available dataset with ground-truth data containing 169 patients from various ethnic groups and levels of DME. This and other two publi…
3D grafikas atveidošana reālā laikā ar Vulkan API
2017
Maģistra darba mērķis veikt pētījumu par dažādām 3D grafikas atveidošanas iespējām uz mūsdienu datoriem, fokusējoties uz Vulkan programmsaskarni (turpmāk API), apskatot tās stiprās un vājas puses kā arī atšķirības no alternatīvām. Līdz šim tirgu ir dominējušas 2 API, lai izmantotu videokartes grafisko procesoru (turpmāk GPU) grafikas atveidošanai – OpenGL un DirectX. Tā kā mūsdienās 3D grafikas detalizācija un sarežģītība ir augoša, ir nepieciešami jauni risinājumi, kas precīzāk atbilst mūsdienu datoru arhitektūrai un ierīču daudzveidībai, kā arī dotu izstrādātājiem lielāku kontroli pār visiem notiekošajiem aprēķinu procesiem. Darba ietvaros ir izstrādāti divi 3D grafikas dzinēji. Vienā ir …
An automated image analysis methodology for classifying megakaryocytes in chronic myeloproliferative disorders
2008
This work describes an automatic method for discrimination in microphotographs between normal and pathological human megakaryocytes and between two kinds of disorders of these cells. A segmentation procedure has been developed, mainly based on mathematical morphology and wavelet transform, to isolate the cells. The features of each megakaryocyte (e.g. area, perimeter and tortuosity of the cell and its nucleus, and shape complexity via elliptic Fourier transform) are used by a regression tree procedure applied twice: the first time to find the set of normal megakaryocytes and the second to distinguish between the pathologies. The output of our classifier has been compared to the interpretati…
URBAN IMAGE | From logo to brand
2018
Corporate image has arised in the last Century as a strategy to assume visual identity and a great power of attraction. By using that strategy, corporations have become a sort of “economic divinity” able to seduce and move the mass of consumers. The aim of the article is to describe how to apply the strategy of corporate image on a pavilion, designed by some students of Hong Kong and Palermo, in order to make it visually relevant and to highlight its strong points, which are connected to light and water. In this perspective, some important cases in the history of design have been anylised with punctual examples, starting from the beginning of Twenty Century to come to todays situation, in w…
Unipa L’immagine della cultura
2017
Nel campo della comunicazione visiva l'immagine aziendale è un mezzo potente per affermare lo stato e l'identità di una società. Infatti, nel ventesimo secolo le aziende più importanti del globo svilupparono ampiamente la loro attività commerciale usando un coordinamento sistematico del design per ogni prodotto e mezzo visivo, dal logo alle testimonianze. L'obiettivo dell'articolo è quello di esaminare come questa strategia, tradizionalmente legata alle società commerciali, possa essere applicata correttamente alle Istituzioni Culturali e, in particolare, alle Università, che sono "corporazioni di cultura". Dopotutto, questi sono concorrenti nella "battaglia delle visibilita" per diversi mo…
