Multi-Objective Design of Optimisation of a Class of PKMs - The 3-DOF Gantry-Tau
2010
The main contribution of this paper is the use of the evolutionary multi-objective methodology based on the com plex search algorithm and geometric approaches to optimise a parallel kinematic structure. The design optimisation scheme includes the kinematic (collisions free workspace), elastostatic (Cartesian stiffness in the Y direction) and elastodynamic (first resonance frequency) properties of the PKM as the objectives. The optimisation constraints are the support frame lengths, actuator positions, end-effector’s kinematic parameters and the robot’s arm lengths. The optimisation results are presented in this paper.
Life cycle energy performances of a Net Zero Energy prefabricated building in Sicily
2017
The paper presents the energy performances in a life cycle perspective of a prefabricated building. The building was simulated in energy plus and validated on monitored data. To avoid the shifting of energy burdens from one life cycle stage to others, a Life Cycle Energy Assessment was performed. The primary energy use throughout the building's life cycle is 1,242 GJ. The materials production stage consumes the highest amount of primary energy (680 GJ) followed by the use stage (484 GJ), while the construction and end-of-life require respectively 1.7 % and the 4.6 % of total primary energy.

The use of wood with an anti-seismic function in the architecture of palermo during the 18th century
2016
The study analyzes the interventions in the historical buildings after the earthquakes that struck Palermo in 1726 and 1751, with a particular attention to the anti-seismic reinforcements. The research, based primarily on archival documents, focuses on a series of interventions in the architectural heritage, in which the use of wood for structural elements, was able to guarantee for an “antiseismic” reconstruction. Although wood was not commonly used as other materials (iron, for instance) in the post-earthquake reconstruction process of Palermo it was certified its use as an anti-seismic system in the reinforcements of the damaged buildings. It is documented, for instance, the insertion of…
Il Paradigm Shift Della Teoria Sistemica Nelle Scienze Sociali: Verso Un Nuovo Concetto Di Impresa Sistemico-Vitale (The Paradigm Shift of Systemic T…
2011
La complessita dell’ambiente sociale e di business ha reso ormai evidente l’imprescindibile necessita, per le organizzazioni complesse (tra cui le imprese) del XXI secolo, di miglioramento della capacita di gestione dei necessari mutamenti al fine di mantenere la vitalita e garantirne la sopravvivenza. L’approccio sistemico si e rivelato cruciale per l’apertura di nuove prospettive di studio e di comprensione delle dinamiche dei sistemi viventi. La comprensione di tali fenomeni si e rivelata di fondamentale importanza per il governo delle organizzazioni complesse. Negli ultimi decenni si e potuto assistere alla crescita della rilevanza strategica della comunicazione per la governance delle …
Wine label design as a strategic tool to attract consumers. A marketing study on Sicilian wine positioning
2013
Negli ultimi anni il packaging e stato considerato dalle aziende vinicole uno tra i piu importanti strumenti del marketing. Infatti, grazie all’utilizzazione di immagini e testi, e possibile comunicare chiaramente al mercato messaggi coerenti con i prodotti, con i valori dell’azienda e con i target di consumatori di riferimento. In questo studio si e voluto conoscere quanto le etichette siano importanti per le cantine siciliane nelle scelte di posizionamento dei loro vini. Si e voluta, inoltre, misurare l’influenza che le etichette esercitano sui consumatori, indirizzando ed orientando le preferenze al momento dell’acquisto di un vino, senza tralasciare l’eventuale effetto attrattivo causat…
Diseño y validación de un cuestionario para conocer la praxis docente del profesorado de flauta travesera en centros superiores de la comunidad valen…
2017
El objetivo del presente estudio es diseñar y validar un cuestionario para conocer la opinión del profesorado de las enseñanzas superiores de flauta travesera de la Comunidad Valenciana sobre la praxis docente. La población de referencia está formada por el conjunto de profesores de flauta travesera de los tres conservatorios superiores de música de la Comunidad Valenciana: CSM “Oscar Esplà” de Alicante, CSM “Joaquín Rodrigo” de Valencia y CSM “Salvador Seguí” de Castellón. El cuestionario fue enviado a toda la población y la muestra generadora de datos resultó ser del 100%. Sin embargo dos de los encuestados no respondieron, por tanto tenemos un sesgo del 33’33%. Se considera que el estudi…

En la part inferior apareix ressenyada la programació dels actes que se celebraran amb motiu del quart centenari de la fundació de la Universitat En primer terme i ocupant quasi tot el cartell, es veu a la Saviesa representada en la figura d'una jove que duu en la mà dreta una torxa encesa i en l'esquerra un llibre. Darrere d'ella, un sol espargeix els seus llamps daurats sobre un cel estrellat; als seus peus hi ha una serp amb cap de drac. En l'extrem dret el segell de la Universitat
Structural Basis of Tumoral Angiogenesis
2003
Mammalian cells require oxygen and nutrients for metabolism and growth. In all cases tissues possess a vascular and lymphatic network assuring the supply of these needs within 200 to 250µm. Multicellular organisms that grow beyond this size require the recruitment of new blood vessels, although some normal tissues are devoid of specific vascularization (cartilage, cornea, epidermis), obtaining their oxygen and metabolic supply through perfusion
Cardiovascular effect of dental anesthesia with articaine (40 mg with epinefrine 0,5 mg % and 40 mg with epinefrine 1 mg%) versus mepivacaine (30 mg …
2011
Objectives: The aim of the present study is to compare cardiovascular safety profiles of two dental anesthetics: articaine versus two standard mepivacaine solutions used during etiological periodontal treatment in cardiovascular patients. Study Design: Using a cross-over study design, ten cardiovascular patients were randomly assigned to dental treatment with 1.8mL of a local anesthetic injected on each quadrant of the mouth: Articaine (40mg with Epinephrine 0.5mg % and 40mg with Epinephrine 1mg %) or Mepivacaine (30mg and 20mg with Epinephrine 1mg %). A computer programme enabled continuous longitudinal data collection: O2 saturation, blood pressure (BP) and heart rate (HR). Results: No se…
