Barbara Sokołowska Brukalski. Graphic Analysis of the House on Niegolewskiego Street
2017
The project analyzed in this paper by the critical and digital redrawing is the House on Niegolewskiego Street of 1927–28, designed by Barbara Sokołowska for her and her husband, Stanislaw Brukalski, inspired by the Neoplasticism ideas, the paintings of Mondrian and De Stijl. In its details the house seems to recall that one in Utrecht by G.T. Rietveld of 1924, with a very large living room, a studio overlooking a double height and a spiral stair connecting the two floors into one space defined by translated planes and pure volumes.
Multitechnique diagnostic analysis and 3D surveying prior to the restoration of St. Michael defeating Evil painting by Mattia Preti
2021
In this study, a multimethodological analysis involving optical and physical/chemical diagnostic techniques and 3D photogrammetric survey was successfully applied, for the first time, on the large oil on canvas St. Michael defeating Evil painting by Mattia Preti, located inside the Church of the Immaculate Conception of Sarria (Floriana) in Malta. Pigmenting agents, binder media, and raw materials were first characterized, both at elemental and molecular scales, through X-ray fluorescence spectroscopy (XRF), optical stereo microscopy (SM), scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM-EDX), Fourier transform infrared spectroscopy (FT-IR), and gas chroma…
PAOLO DI VITA 規則和/或情感 / PAOLO DI VITA, the rule and/or the emotion
2009
Paolo Di Vita是 - 如果我們試圖用一個形容詞來描述他 - 一個謹慎的平面設計師，這種品質不僅區分了他的作品，也區別於他的氣質。從這個意義上說，他私人生活和職業生活的兩個領域相互配合，相互滲透，產生了和諧的連貫性，勾勒出一個具有明確的道德和責任觀念的人物。外觀並不起次要作用，相反，它有助於我們進入並理解其設計世界，在那裡沒有形式主義，流行趨勢，奉承或眨眼的方式。所使用的每一個元素，無論是顏色，形狀，字體還是圖像，都是明智的比例，因為廚師會在配料中加入配料，這些配料不會對口感產生即時的慷慨影響，但需要一些時間才能產生。自己起來，慢慢品味。 同樣，Paolo Di Vita的作品有時呈現出外觀粗糙，這是一種阻礙觀察者立即參與的障礙，因為它們並不總是容易掌握並需要進一步努力才能完全理解除了在表面，也是更隱蔽的層面，紙張上建立的連接網絡支持強烈的緊張情緒，有時通過虛線，切口和划痕可見。 Paolo Di Vita is - if we would try to describe him with an adjective - a discreet graphic designer, and this is a quality which distinguishes not just his work but also his temperament. In this sense, the two spheres of his private and professional life, well match and permeate each other, generat…
Optimized Parallel Implementation of Face Detection based on GPU component
2015
Display Omitted An algorithm for face detection has been implemented on CPU.An acceleration of this algorithm on GPU migration.Performance of GPU implementation shows the effectiveness of this implementation.Another optimization method on GPU are operated. Face detection is an important aspect for various domains such as: biometrics, video surveillance and human computer interaction. Generally a generic face processing system includes a face detection, or recognition step, as well as tracking and rendering phase. In this paper, we develop a real-time and robust face detection implementation based on GPU component. Face detection is performed by adapting the Viola and Jones algorithm. We hav…
A distributed genetic algorithm for restoration of vertical line scratches
2008
This paper reports a distributed algorithm for the restoration of still frames corrupted by vertical line scratches. The restoration is here approached as an optimisation problem, and is solved using an ad-hoc Genetic Algorithm. The distributed algorithm is designed following a pipeline logical structure. The front end is a network of standard workstations with heterogeneous operating systems. The quality of image is appreciable and the computational time is quite low with respect the sequential version.
Dynamic interface for machine vision systems
2002
Iconic programming intends to provide expressive tools to implement, to debug, and to execute programs. For this purpose, visual languages need pictorial constructs and metaphors to guide the design of algorithms in interactive fashion. In the paper a new class of dynamic visual interfaces, named DIVA (Dynamic Interface for Visual Applications), is introduced, its properties are described, and an application to visual compilers in a multi-processors system dedicated to image analysis is given. Moreover, a formal definition of dynamic icon (DI) is also given.
A solution process for simulation-based multiobjective design optimization with an application in the paper industry
2014
In this paper, we address some computational challenges arising in complex simulation-based design optimization problems. High computational cost, black-box formulation and stochasticity are some of the challenges related to optimization of design problems involving the simulation of complex mathematical models. Solving becomes even more challenging in case of multiple conflicting objectives that must be optimized simultaneously. In such cases, application of multiobjective optimization methods is necessary in order to gain an understanding of which design offers the best possible trade-off. We apply a three-stage solution process to meet the challenges mentioned above. As our case study, w…
Paysage & [et] infrastructures de transport : modélisation des impacts des infrastructures sur les réseaux écologiques
2013
The development of linear infrastructures leads to the fragmentation and the artificialisation of the landscape across scales. Landscape fragmentation is a spatial process that is accompanied by a progressive decrease of the connectivity between the elements needed to conduct ecological processes. Thus, maintaining a good level of connectivity between natural habitats, compatible with human activities, has become a major issue for the preservation of biodiversity.By mobilizing methods from graph theory and landscape ecology, the thesis seeks to demonstrate the value of landscape graphs to model ecological networks and analyze impacts of transportation infrastructures at regional scale.The m…
Graphical models for estimating dynamic networks
2012
Het bepalen van dynamische netwerken met behulp van data is een actief onderzoeksgebied, met name in de systeem biologie. Het schatten van de structuur van een netwerk heeft te maken met het bepalen van de aan of afwezigheid van een relatie tussen de hoekpunten in de graaf. Grafische modellen definiëren deze relaties via conditionele afhankelijkheid. In Gaussiaanse grafische modellen (GGM) wordt verondersteld dat de hoekpunten een normale verdeling volgen. Dit heeft grote voordelen vanwege de computationele handelbaarheid van GGM. Standaard GGM zijn echter niet bruikbaar om grote netwerken te bestuderen, i.e. als het aantal waarnemingen minder is dan het aantal hoekpunten van de graaf. Rece…
A 3D reworking of the urban transformations of Palermo in recent history for a hypothesis of a "City Museum" based on digital visualizations
2021
The objective that drives this research is given by a multitude of information which, in addition to the contribution of technology, allows us to study, analyze, verify and remodel the sites, monuments and evolutions of the city through graphic processes of perspective restitution that start from the analysis of historical photos. The drawing methods, the digital graphic rendering and through the aid of geometric techniques, contribute to the reconstruction of projects and architectures that are now lost, this is possible thanks to the methods of perspective, axonometry and three-dimensional restitution. This remarkable photographic heritage belonging to Palermo, but also to any other city …
