Prospettiva solida: il caso della Cattedrale di Palermo

2014

Il panorama culturale architettonico ed artistico del capoluogo siciliano, è così ricco sia in termini di qualità che di varietà, da offrire sempre nuovi spunti di ricerca, interpretazione, elaborazione e rivisitazione. In particolar modo, per quanto concerne gli elementi scultorei e pittorici in cui sono presenti esempi di prospettiva solida, come teatrini, formelle, volte con finte prospettive, quadraturismo, tromp-oeil, ed altro ancora, vi è, sul territorio, una tale quantità e varietà di applicazioni che il loro studio meriterebbe un’attenzione a parte. In seno a questa ricerca su scala Nazionale, considerate le non adeguate forze lavoro a disposizione, è in corso la catalogazione degli…

EntityBot: Supporting Everyday Digital Tasks with Entity Recommendations

2021

Everyday digital tasks can highly benefit from systems that recommend the right information to use at the right time. However, existing solutions typically support only specific applications and tasks. In this demo, we showcase EntityBot, a system that captures context across application boundaries and recommends information entities related to the current task. The user’s digital activity is continuously monitored by capturing all content on the computer screen using optical character recognition. This includes all applications and services being used and specific to individuals’ computer usages such as instant messaging, emailing, web browsing, and word processing. A linear model is then …

An Effective Method to Model the Combustion Process in Spark Ignition Engines

2022

A numerical simulation is a fundamental tool in the design and optimization procedure of an Internal Combustion (IC) engine; since combustion is the process that mostly influences the engine performance, efficiency and emissions, an effective combustion submodel is fundamental. A simple, nonpredictive way to simulate the combustion evolution is to implement a mathematical function that reproduces the mass fraction burned (MFB) profile that is characterized by a sigmoidal trend; the most used for this purpose is the Wiebe function. In this article the authors propose a different mathematical model, a Dose-Response (DR) type function that shows some benefits when compared to the Wiebe functio…

First analyses on a mechanical motion converter to produce electrical energy from sea wave

2020

The exploitation of sea wave opens new horizon for suppling small islanded communities. With this goal the paper propones a prototypical device for the utilization of sea wave along the coastline. The device is based on a mechanical motion conversion, from an alternative rotation into unidirectional rotation in order to run commercial generators. First evaluations are here reported, demonstrating the feasibility of this solution.

Implementing the sustainable energy (and climate) action plans: quasi-steady state or dynamic building modeling approach?

2020

Actions contemplated in Sustainable Energy (and Climate) Action Plans (SEAPs), which municipalities adhering to the EU initiative called “The Covenant of Mayors” are required to prepare, regard many sectors, among which are buildings. To implement such plans, it is necessary to make use of methods for predicting energy use in buildings. Technicians involved in this tend to adopt easy-touse simulation models because of the common mid-level expertise of the offices involved. However, such simplified methods could result in a less accurate evaluation of the energy demand of buildings. In this paper the suitability of the quasi-steady state and the dynamic approach, in the frame of these new ur…

STRUCTURAL DETERMINISTIC MODELING DESIGN AND FABRICATION OF ELECTROSPUN SCAFFOLDS FOR SOFT TISSUE ENGINEERING

2011

The research fields of tissue engineering, biomechanics and regenerative medicine continue to evolve in response to the ever growing need for tissue replacement options. These fields aim to restore, maintain, or improve tissue or whole organ function. This doctoral studies focus on the development and experimental validation of a structural deterministic modeling strategy to: A) guide tissue engineering scaffold design, B) provide a better understanding of cellular mechanical and metabolic response to local micro-structural deformations. Targeted clinical application was the pulmonary heart valve. Electrospinning was selected as the optimal platform technology to implement, validate and tes…

Flax–Glass Fiber Reinforced Hybrid Composites Exposed to a Salt-Fog/Dry Cycle: A Simplified Approach to Predict Their Performance Recovery

2023

Despite natural fibers gaining significant attention in recent decades, their limited performance and poor durability under humid environments cannot allow them to fully replace their synthetic counterparts as reinforcement for structural composites. In such a context, this paper aims to investigate how exposure to a humid/dry cycle affects the mechanical response of epoxy laminates reinforced with flax and glass fibers. In particular, the main goal is to assess the performance evolution of a glass–flax hybridized stacking sequence in comparison with the full glass and flax fiber reinforced composites. To this end, the investigated composites were first exposed to salt-fog for 15 or 30 days…
