RECYCLING SPENT COFFEE WASTE FOR INNOVATIVE THERMO-PLASTERS: DEVELOPMENT OF A PROTOTYPE
2022
This paper presents an experimental study aimed at testing the real energy performance of a thermo-plaster prototype made of an ordinary mortar boosted by various percentages of spent coffee ground. That is one of the wastes of the brewing process that are usually disposed of in landfill with great concerns for the possible environmental footprint due to its organic nature and possible harmful components. In this paper, the mortar was manufactured froman ordinary Portland cement and sand, partially substituted by the waste. Specimens characterization is briefly outlined and a careful examination of the thermal properties is carried out. A plastering prototype was manufactured and placed in …
The use of sea waves for generation of electrical energy: a linear tubular asynchronous electrical generator
2007
A linear tubular asynchronous generator to be used as generator driven by seawave is presented. The design criteria of a TLIM with hollowed iron induced part as well as the technological processes to be adopted and the materials utilized in the various parts are described. The methodologies for mechanical assembling and electric wiring are considered too. Finally, the prototype with bimetallic induced part that has been designed and built is presented and some experimental results on electrical and mechanical variables are shown.

Prototipi per rigenerare Palermo
2021
Il contributo presenta e descrive criticamente le sperimentazioni progettuali per la città di Palermo elaborate all’interno del Laboratorio “Cosmopolitan Habitat” del Corso di Laurea Magistrale in Architettura del Dipartimento di Architettura dell’Università degli Studi di Palermo, giungendo all’elaborazione di prototipi di futuro possibile, progetti di conservazione, innovazione e trasformazione di alcune parti di città che fungono da esemplificazioni di soluzioni e da esposizione di processi. L’attenzione si è rivolta soprattutto alla generazione di “luoghi mondo”, ovvero luoghi che fungano da nodi locali di reti globali a supporto di una città policentrica e della cultura cosmopolita, in…
A Sliced Coprocessor for Native Clifford Algebra Operations
2007
Computer graphics applications require efficient tools to model geometric objects. The traditional approach based on compute-intensive matrix calculations is error-prone due to a lack of integration between geometric reasoning and matrix-based algorithms. Clifford algebra offers a solution to these issues since it permits specification of geometry at a coordinate-free level. The best way to exploit the symbolic computing power of geometric (Clifford) algebra is supporting its data types and operators directly in hardware. This paper outlines the architecture of S-CliffoSor (Sliced Clifford coprocessor), a parallelizable embedded coprocessor that executes native Clifford algebra operations. …
The ALICE Transition Radiation Detector: Construction, operation, and performance
2018
The Transition Radiation Detector (TRD) was designed and built to enhance the capabilities of the ALICE detector at the Large Hadron Collider (LHC). While aimed at providing electron identification and triggering, the TRD also contributes significantly to the track reconstruction and calibration in the central barrel of ALICE. In this paper the design, construction, operation, and performance of this detector are discussed. A pion rejection factor of up to 410 is achieved at a momentum of 1 GeV/$c$ in p-Pb collisions and the resolution at high transverse momentum improves by about 40% when including the TRD information in track reconstruction. The triggering capability is demonstrated both …
EXTERNAL RECIRCULATION IN PRS TYPE TURBINE: EXPERIMENTAL AND NUMERICAL RESULTS.
2022
Cavitation is a relevant phenomenon for structural safety and noise level in hydraulic turbines, occurring when water pressure falls below the vapor value at a given temperature. In this case bubbles of vapor grow inside the liquid and move along with it. When the pressure returns above the vapor value the bubble collapses, and the pressure can locally achieve very high values, up to 7000 bars (Kumar & Saini, 2010). Moreover, if the bubble was confined also by the solid wall of a blade, the solid particles suspended in the fluid can be transported by the fluid ones and hit the solid wall at very high velocity, generating erosion. Cavitation is also the source of high frequency noise, ve…
A Dual-Core Coprocessor with Native 4D Clifford Algebra Support
2012
Geometric or Clifford Algebra (CA) is a powerful mathematical tool that is attracting a growing attention in many research fields such as computer graphics, computer vision, robotics and medical imaging for its natural and intuitive way to represent geometric objects and their transformations. This paper introduces the architecture of CliffordCoreDuo, an embedded dual-core coprocessor that offers direct hardware support to four-dimensional (4D) Clifford algebra operations. A prototype implementation on an FPGA board is detailed. Experimental results show a 1.6× average speedup of CliffordCoreDuo in comparison with the baseline mono-core architecture. A potential cycle speedup of about 40× o…
Identifying opportunities for AI applications in healthcare — Renewing the national healthcare and social services
2018
A vast variety of artificial intelligence techniques have been deployed to specific healthcare problems during the last thirty years with varying levels of success while there is a shortage of systematic matching of AI capabilities with the breadth of application opportunities. In this paper, we describe the process of identifying opportunities for deploying artificial intelligence to healthcare and social services on regional and national levels in Finland. The project involved a large number of stakeholders from a variety of backgrounds ranging from governmental agencies to entrepreneurs. The process described includes idea generation of an application or solution and its elaboration in w…
