Intelligent Management Systems for Energy Efficiency in Buildings: A Survey

2014

In recent years, reduction of energy consumption in buildings has increasingly gained interest among researchers mainly due to practical reasons, such as economic advantages and long-term environmental sustainability. Many solutions have been proposed in the literature to address this important issue from complementary perspectives, which are often hard to capture in a comprehensive manner. This survey article aims at providing a structured and unifying treatment of the existing literature on intelligent energy management systems in buildings, with a distinct focus on available architectures and methodology supporting a vision transcending the well-established smart home vision, in favor o…

Design Space Exploration of Parallel Embedded Architectures for Native Clifford Algebra Operations

2012

In the past few decades, Geometric or Clifford algebra (CA) has received a growing attention in many research fields, such as robotics, machine vision and computer graphics, as a natural and intuitive way to model geometric objects and their transformations. At the same time, the high dimensionality of Clifford algebra and its computational complexity demand specialized hardware architectures for the direct support of Clifford data types and operators. This paper presents the design space exploration of parallel embedded architectures for native execution of four-dimensional (4D) and five-dimensional (5D) Clifford algebra operations. The design space exploration has been described along wit…

Oggetti quotidiani ed estetica dell’abitare. Riflessioni sul design anni ’50 e ’60 in Italia

2023

Il saggio prende in considerazione alcuni oggetti presentati alla mostra Design! Oggetti, processi, esperienze, di cui il volume costituisce il catalogo, per dimostrare come oggetti, suppellettili e accessori costituiscono un indizio delle abitudini di chi abita la casa, testimonianza di memorie e affetti, espressione di un’identità. Di conseguenza, gli oggetti, intesi in senso etico-estetico e antropologico, assurgono a chiave euristica per ripensare, in termini non cumulativi ma relazionali, i modi in cui viene elaborata l’estetica dell’abitare.

Design and analysis of discrete choice experiments for models with response time

2013

Settore SECS-S/02 - Statistica Per La Ricerca Sperimentale E TecnologicaA sector of conjoint analysis (experimental design in marketing research) is made of the so called choice experiments. In choice experiments respondents undergo a questionnaire which is nowadays mostly submitted through the internet. The questionnaire proposes to the respondent a sequence of choice sets each one including two or more profiles being a profile a specific combination of attribute levels. The respondent selects the preferred profile for each choice set. Responses given by a sample of respondents are analysed through suitable methods aimed to eventually find the best combination of attribute levels. One method of analysis adopts the Multinomial Logit (MLN) model. In this article the authors show the results of the MLN analysis compared with another model of analysis which uses an additional response which can be easily recorded by electronically submitted questionnaires. In practice modern survey platforms like “Qualtrics” (the one used for this work) can record the so called “response latency” i.e. the time taken by the respondent to make the choice and select the most preferred profile in the choice set. Thanks to a response latency model further refined in this work it is possible to deduce the relative weight of importance of the profiles for each choice set and respondent. This type of response can be used in place of the dichotomous choice variable in the MLN model. The two models and methods of analysis are deeply compared and it is critically discussed when it is better to use one or the other method. As a result a more reliable estimate of the optimal profile comes up implying lower risks for new investments and marketing decisions.

Prioritization of the balancing property and full estimability in mixed-level designs

2008

In a recently published work, a new class of Balanced Asymmetrical Nearly Orthogonal Designs (BANOD2) was proposed, which can simultaneously estimate both first and second order effects of all factors, with a limited run size. The motivation for the new class lies in using the balancing property as a necessary precondition for several practical concerns arising in the experimentation field. A balanced design optimizes the use of experimental resources in technological experiments, may avoid misinterpretations in choice experiments of marketing research, and can relieve the experimenter from the arbitrariness in assigning the levels to factors. Furthermore the balancing property assures the …

Computer experiments combined with physical Experiments: two experiences in product development

2012

Physical experiments in industrial product development are often very expensive but also necessary sometimes even for safety reasons (think about the crash tests in the automotive industry conducted with new and completely equipped vehicles). Therefore there is a pressing need to reduce this cost as much as possible. Computer experiments may be a viable solution provided that their results are reliable as much as the physical ones. In most of the cases, computer experiments are opportunely combined with physical experiments and the recipe of such mix is interesting itself. In this presentation we will show two cases of combination of physical and computer experiments in product development.…

“Sicilia”. Una, nessuna, centomila Sicilie / ‘Sicilia’. One, no one and one hundred thousand Sicilies

2013

Sicilia, è una rivista che ancora oggi ha molto da raccontare e insegnare, nella sua assoluta visionarietà così costantemente in bilico tra l’essere un periodico visceralmente siciliana e ancor più palermitana e l’essere una rivista internazionale, contemporanea, poliglotta, sperimentale e proiettata verso nuovi scenari. Sicilia, senza timore di potere essere tacciata di inutile campanilismo, merita di essere studiata in modo ben più approfondito di quanto sia stato fatto sinora, attraverso un’attenta analisi condotta nei diversi ambiti disciplinari coinvolti tra le pieghe delle sue pagine. In questa sede proveremo ad approfondire il suo studio analizzando la rivista, quale complesso artefa…

Advanced Statistical Tools for Six Sigma and other Industrial Applications

Six Sigma is a methodological approach and philosophy for quality improvement in operations management; its main objectives are identifying and removing the causes of defects, and minimizing variability in manufacturing and business processes. To do so, Six Sigma combines managerial and statistical tools, with the creation of a dedicated organizational structure. In this doctoral thesis and the three years of study and research, we have had the purpose to advance the potential applications of the methodology and its tools; with a specific attention on issues and challenges that typically prevent the realization of the expected financial and operational gains that a company pursue in applyin…

Advances in designing drip irrigation laterals

2018

It is known that using paired laterals, in which two distribution pipes extend in opposite directions from a common manifold, contribute to increasing water use efficiency (WUE). Recently, an analytical procedure to optimally design paired drip laterals on uniform slopes was proposed. More recently, this design procedure was simplified by deriving simple explicit relationships, as a function of 16 calibration constants, with relative errors that were less than 2%. In this paper, further simple design relationships are derived that require only 3 calibration constants, thus more readily obtainable results are produced and the influence of the flow rate and diameter exponents of resistance eq…
