We hereby focus the study of the Albertian column system, as part of the Digital Alberti project, a research initiative that aims to shed some light on the influence of Alberti on Portuguese architecture. Starting from Alberti’s treatise on architecture, De Re Aedificatoria, and its translation into Portuguese, Da Arte Edificatória, a generative computational model was developed that encodes Alberti’s prescriptions about the elements of the column system, as well as their proportions and shapes.  This research complements the elaboration of the corresponding shape grammar on Alberti’s column system. This project is a paradigmatic example of the use of digital technology for understanding architectural tradition. The development of the referred models implied deepening the understanding of Alberti’s rules about the column elements. This in-depth analysis revealed a very coherent hierarchical structure ruling the relationships among the several elements. It also revealed that information was insufficient to inform a formal model of all them, especially the ones showing more complex geometry, such as the corinthian and composite capitals. Therefore, it can be considered that the application of digital technologies allowed to more accurately understand and reproduce Alberti’s guidelines for the art of building.Foca-se o estudo do sistema de coluna Albertiano, no âmbito do projecto Alberti Digital, cuja investigação pretende elucidar sobre a influência de Alberti na arquitetura portuguesa.

The paper will show parts of a shape grammar that uses as corpus the Alberti`s treatise and buildings to see possible influence in Portuguese Architecture. The column systematisation grammar is a grammar of detail and some of the different elements of the column system (base, shaft, capital and entablature) may be connected with different orders (Doric, Ionic, Corinthian and Composite) showing different combinations. This system may be applied to generate some buildings namely Rucellai Loggia and palace facade, Santa Maria Novella Facade, Santa Andrea and specifically the subject of this paper the central nave longitudinal façade of the church São Vicente de Fora in Lisboa. Finally transformations rules are analysed mapping Alberti`s treatise influence in the work of the authors of the generated building.  Gramatica da forma da sistematização das ordens da Da arte edificatóriaEste artigo mostra partes de gramatica da forma que usa como corpos o tratado de Alberti bem como alguns dos seus edifícios de modo a verificar a influência daquele autor na Arquitetura Portuguesa. A gramática da sistematização da coluna é uma gramática de detalhe. Alguns dos elementos do sistema da coluna (base, fuste, capitel e entablamento) podem ter elementos de diferentes ordens (dórica, jónica, coríntia e compósita) em diferentes combinações. Este sistema pode ser aplicado gerando a Loggia e a fachada do palácio Rucellai, a Fachada de Santa Maria Novella, nave central da fachada longitudinal da igreja Sant`Andrea e tratado especificamente neste artigo a nave central da fachada longitudinal da igreja de São Vicente de Fora em Lisboa. Finalmente as regras de transformação são analisadas mapeando a influencia do tratado de Alberti no trabalho dos autores do edifício gerado.

AbstractThis paper shows the way Leon Battista Alberti treatise De Re Aedificatoria column systematization shape grammar was built, and how the longitudinal elevation of the nave of the Sant'Andrea church was designed, evidencing some steps involved in the grammar construction process, its derivation, and the partial outputs gained from the grammar evaluation. The goal of this grammar is to infer Alberti's treatise rules through a computational approach evidencing its algorithmic nature, illustrating it, and understanding the De Re Aedificatoria rules that may be applied in the generation of some parts of buildings such as the Sant'Andrea church, showing a complementary method to archaeological, bibliographical, historical ones, among others, that have been used to understand the built environment. The rules provided by the grammar may be applied to an initial insertion point to produce a complete column and to a pre-existing plan or section element of a building generating its facade. It was proved, evaluating the grammar with a simple linear regression method, to what extent the treatise influenced the design of the facade in the study.

Sometimes, it is impossible to conduct tests with the use of the GNSS system, or the obtained results of the measurements made differ significantly from the predicted accuracy. The most common cause of the problems (external factors, faulty results) are interference disturbances from other radio telecommunication systems. The subject of this paper is to conduct research, the essence of which is an in-depth analysis in the field of elimination of LTE interference signals of the GNSS receiver, that is based on the developed effective methods on counteracting the phenomenon of interference signals coming from this system and transmitted on the same frequency. Interference signals are signals transmitted in the GNSS operating band, and unwanted signals may cause incorrect processing of the information provided to the end-user about his position, speed, and current time. This article presents methods of identifying and detecting interference signals, with particular emphasis on methods based on spatial processing of signals transmitted by the LTE system. A comparative analysis of the methods of detecting an unwanted signal was made in terms of their effectiveness and complexity of their implementation. Moreover, the concept of a new comprehensive anti-interference solution was proposed. It includes, among others, information on the various stages of GNSS signal processing in the proposed system, in relation to the algorithms used in traditional GNSS receivers. The final part of the article presents the obtained research results and the resulting significant observations and practical conclusions.

De Re Aedificatoria

Desde la propuesta teórica de Alberti en De re aedificatoria (ca. 1450-1485), el camino de acceso a la villa constituye uno de sus componentes definidores por excelencia, integrado muy tempranamente como parte de su composición general. En relación con este elemento de ordenación, se estudia un conjunto de villas que presentan desarrollo axial –principalmente dentro del tipo aterrazado– con viales de acceso de notable longitud, todas dentro del período renacentista, desde el ejemplo más antiguo de Quaracchi (ca. 1453) o Castello (ca. 1538-1550), entre otros de Toscana, entorno de Roma o el Véneto, hasta casos españoles como La Fresneda (ca. 1562-1569) o El Bosque de Béjar (ca. 1567).

De Re Aedificatoria

En los diez libros que conforman De re aedificatoria, el tratado de arquitectura de Leon Battista Alberti, la ruina expresa un modelo y una moraleja: es el último reducto donde anidan los rastros de una sabiduría perdida, y la firme consecuencia de un tiempo que todo lo devora, en sintonía con la violencia de la historia. A partir de esta doble enseñanza, Alberti busca instalar en su tratado ciertos principios de estabilidad. Buscando comprender estos principios, en el presente artículo nos proponemos analizar los conceptos de lineamenta (diseño) y materia (materiales) que el humanista nacido en Génova desarrolla en los dos primeros libros de su tratado, y ubicarlos en el marco de una historia construida, destruida, y vuelta a construir.
