Perizie sulla stabilità di cupole e campanili della Sicilia centro-orientale nel secondo Settecento

2015

Il saggio analizza episodi di criticità strutturali relativi a cupole e campanili della Sicilia del secondo Settecento (chiese Madri di Ragusa, Piazza Armerina e Caltagirone). In particolare verranno esaminati i progetti ex novo e le perizie redatti dall’architetto catanese Francesco Battaglia sulle problematiche relative al comportamento statico di strutture spingenti, come le cupole e le volte, o alte e isolate, come i campanili, di cui l’architetto propone soluzioni finalizzate alla loro fortificazione e sicurezza. Diverse relazioni tecniche, di cui alcune inedite, stilate da Battaglia nella seconda metà del XVIII secolo e talune in risposta ad altrettante perizie richieste a rinomati pr…

Small Wind Turbines: Specification, Design, and Economic Evaluation

2016

In this work, we consider various aspects of small wind turbines' (SWTs) design and operation. First, an extensive literature study is presented by considering SWTs specification, market statistics, the smart grid, and the prosumer concepts as well as the most important parameters affecting the efficiency of wind turbines. Then, both the literature review and series of coupled numerical simulations investigating impact of the chosen design solutions on small wind turbine operation are performed. It allowed objective evaluation of different design approaches, which in turn enabled the systematic identification of actual limitations as well as the opportunities for specific design solutions o…

Reviewing the impact of problem structure on planning: a software tool for analyzing tower tasks.

2010

Cognitive, clinical, and neuroimaging studies on planning abilities most frequently implement the Tower of London task or one of its variants. Yet, cumulating evidence from a series of experiments suggests that the commonly used approximation of problem difficulty in terms of the minimum number of moves for goal attainment is too coarse a measure for the underlying cognitive operations, and in some cases may be even misleading. Rather, problem difficulty can be more specifically characterized by a set of structural task parameters such as the number and nature of optimal and suboptimal solution paths, the required search depths, the patterns of intermediate and goal moves, goal hierarchies …

Study on Interfacial Surface in Modified Spray Tower

2019

This paper presents an analysis of the changes in interfacial surface and the size of droplets formed in a spray tower. The interfacial surface and the size of droplets formed are of fundamental importance to the performance of the equipment, both in terms of pressure drop and process efficiency. Liquid film and droplet sizes were measured using a microphotography technique. The confusors studied were classical, with profiled inside surface, and with double profiled inside surface. The liquids studied were water and aqueous solutions of high-molecular polyacrylamide (PAA) of power-law characteristics. The ranges of process Reynolds number studied were as follows: ReG &isin

Il volume Tommaso Maria Napoli Utriusque Architecturae Compendium Roma 1688 Breve trattato sulle fabbriche civili e militari e la conservazione delle architetture del frate domenicano Tommaso Maria Napoli, vuole contribuire ad accrescere le nostre conoscenze sui principi che dovevano sottendere alla realizzazione dell’architettura civile e militare del periodo barocco e tardo barocco, così come espressi nel breve trattato scritto dal frate architetto, nato a Palermo, Tommaso Maria Napoli (1659-1725), e pubblicato a Roma alla fine del Seicento. Alla traduzione dal latino del trattato, redatta da esperti (Fabio Zarbo e Pietro Zarbo), è inclusa un’interessante ricerca, redatta congiuntamente c…

Infographic techniques for the representation of marginal buildings of Salerno coast

2016

By means of this article, it proposes a cognitive study of the coastal defence system of Amalfi; place rich in history, which is well suited as a case study to experiment the innovative digital techniques for the representation and preservation of cultural heritage. The interpretation of the building, its forms and its nature has been developed through the integration of monoscopic photogrammetry with BIM, this in order to reach the realization of an infographic image summary with the high knowledge content, and for the enhancement and conservation of these architectures

The Technologies of Architectural Survey: A New Comparison Based on the Tower of Sotillo de la Ribera, Burgos

2017

The paper offers an original research about the analysis and the comparison of different techniques of survey concerning the architectural field – image-based and range-based – throughout the development of the theory of errors in order to evaluate reliability and precision of the results. In particular, this analysis will be focused on the tower of the parochial Church of Santa Águeda, a building located in the small village of Sotillo de la Ribera, within the province of Burgos (Spain). The first part of this work, therefore, has been submitted to the implementation of different methodologies, from the direct survey used as a basis, to the procedure to represent graphically the results (e…

Unity bāzēta “Tower Defense” spēle

2022

Kvalifikācijas darba ietvaros tika izstrādāta Unity bāzēta “Tower Defense” lietotne, kuras autors ir Vitālijs Aņisimovs un darba vadītājs Dr.sc.comp. Edgars Diebelis. Lietotnes (turpmāk spēles) darbības princips un īss raksturojums: Spēles ietvaros lietotājam ir iespēja izvēlēties apkārtni, kurā notiks darbība, galvenais mērķis ir sasniegt pēc iespējas augstāku līmeni, izvietojot apkārtnē torņus, ar kuru palīdzību ir iespējams iznīcināt pretiniekus (šajā gadījumā mākslīgo intelektu), saņemot valūtu, ar kuras palīdzību ir iespējams uzlabot torņus un palielināt iespēju tikt līdz nākamajam līmenim, jo, sasniedzot nākamo līmeni, sarežģītība tiek palielināta tā, lai spēle būtu dinamiska un piepr…

A computational method to optimal control of a wind turbine system using wavelets

2011

Author's version of a chapter in the book: Proceedings of the IEEE International Syposium on Computer-Aided Control System Design (2011). Also avaliable from the publisher at: http://dx.doi.org/10.1109/CACSD.2011.6044551 This paper deals with a computational optimization approach to the problem of state-feedback control design for a wind turbine system. The first step of the study is to develop a reduced order model for the system by considering the most important physical phenomena of aerodynamics and structural dynamics. Moreover, the behavior of the system can be influenced by the coupled dynamics between the tower motions and the blade pitch and turbine speed which can cause instabiliti…
