Employing fuzzy logic in the diagnosis of a clinical case
2010
Fuzzy logic is a logical calculus which operates with many truth values (while classical logic works with the two values of true and false). Since fuzzy logic considers the truth of scientific statements like something softened, it is fruitfully applied to the study of biological phenomena, biology is indeed considered the field of complexity, uncertainty and vagueness. In this paper fuzzy logic is successfully applied to the clinical diagnosis of a patient who suffers from different diseases bound by a complex causal chain. In this work it is presented a mathematical foundation of fuzzy logic (with connectives and inference rules) and then the application of fuzzy reasoning to the study of…
Cloud Services Pricing Models
2013
A major condition for commercial success is a well-defined pricing strategy, however, cloud service providers face many challenges around pricing. Clearness and transparency in pricing is beneficial for all the actors in the ecosystem, where the currently existing abundance of different pricing models makes decision making difficult for service providers, partners, customers and competitors. In this paper, the SBIFT pricing model is evaluated and updated to cloud context. As a result, a 7-dimensional cloud pricing framework is proposed that helps clarifying the possible pricing models in order to let companies differentiate themselves from competitors by price. The framework can be used als…
Performances of the Fault Decoupling Device when unbalanced and multiple faults occur on distribution systems.
2005
Nowadays industrial processes are largely based on electronic devices such as programmable logic controllers and adjustable speed drives. Consequently, industrial equipments became less tolerant towards power supply disturbances. Voltage dips due to faults are surely among the worst disturbances for industrial equipments. A paper machine can be affected by disturbances of only 10% voltage drop lasting for 100 ms. A voltage dip of 75% (of the nominal voltage) with a duration shorter than 100 ms results in material loss in the range of thousands of US Dollars for semiconductors industry [1].
A hardware skin-segmentation IP for vision based smart ADAS through an FPGA prototyping
2017
International audience; In this paper we presents a platform based design approach for fast HW/SW embedded smart Advanced Driver Assistant System (ADAS) design and prototyping. Then, we share our experience in designing and prototyping a HW/SW vision based smart embedded system as an ADAS that helps to increase the safety of car's drivers. We present a physical prototype of the vision ADAS based on a Zynq FPGA. The system detects the fatigue state of the driver by monitoring the eyes closure and generates a real-time alert. A new HW/SW codesign skin segmentation step to locate the eyes/face is proposed. Our presented new approach migrates the skin segmentation step from processing system (S…
L'analogia physis-techne in Aristotele (Fisica B, 3-9) e la teoria interventistica della causalità
2015
Ho diviso la lettura dei capitoli 3-9 del libro B della Fisica di Aristotele in due momenti: nei capitoli 3-7 viene data la definizione delle quattro cause e si pone il problema se caso e fortuna sono cause del divenire, nei capitoli 8-9 si risolve tale aporia in senso teleologico e si traggono le conclusioni sulla relazione physis-techne. La concezione interventistica della causalità sostiene che c’è uno stretto legame fra causalità e intervento umano in natura: l’idea di una relazione causale fra due eventi (uno che causa e l’altro che è causato) ha come presupposto il concetto di azione intenzionale e nasce dalla riflessione dell’uomo sul proprio operare finalizzato nella realtà. Sebbene…
Definizione e significati della physis in Aristotele a partire dal confronto con la techne Il logos come apertura della physis alla techne in Fisica …
2015
Oltre all' idea della genesi della dottrina delle cause dal confronto fra techne e physis, l’ipotesi che guida questo studio, a tale idea strettamente connessa, è l’interpretazione della techne aristotelica come sussunzione del divenire naturale, e delle sue catene causali, entro l’operare umano in vista di un fine: la similitudine fra techne e physis viene colta da Aristotele nell’essere entrambe movimenti che producono enti imponendo una forma ad una materia adeguata e secondo un piano finalizzato; in entrambi questi processi la causa formale e la causa finale del movimento giungono, da un certo punto di vista, ad identificarsi.
Model analysis of uniaxial and biaxial stretching of polymer melts
1976
The biaxial extension results byDenson et al. are compared with the predictions of a model of non-linear viscoelasticity. Date of uniaxial extension on the same material (a commercial polyisobutylene) are taken for extending the comparison. The model used seems to adequately describe both types of elongational flow with the same value of the single adjustable parameter.
Theory and Simulation of Multiphase Polymer Systems
2010
The theory of multiphase polymer systems has a venerable tradition. The 'classical' theory of polymer demixing, the Flory-Huggins theory, was developed already in the forties of the last century. It is still the starting point for most current approaches -- be they improved theories for polymer (im)miscibility that take into account the microscopic structure of blends more accurately, or sophisticated field theories that allow to study inhomogeneous multicomponent systems of polymers with arbitrary architectures in arbitrary geometries. In contrast, simulations of multiphase polymer systems are relatively young. They are still limited by the fact that one must simulate a large number of lar…
¿Quién decide qué y cómo? el conflicto en torno a la participación ciudadana en el contexto del desarrollo de la iniciativa urbana: Cuenca-San Antón …
2018
This article describes the main results of an ethnographic study on citizen participation carried out in the context of the development of the Urban Initiative (2007-2015): Cuenca-Barrio de San Antón. Managed by the City Council of Cuenca and financed by the European Regional Development Funds (FEDER) under the Ministry of Economy and Finance at the Government of Spain The results of the research show how in the context of the application of neoliberal policies, citizen participation becomes the trigger for new conflicts between institutions and citizens. In this sense, it is worth noting how, in practice, institutions in their capacity as experts and not willing to dis-empower themselves, …
Computational cluster validation for microarray data analysis: experimental assessment of Clest, Consensus Clustering, Figure of Merit, Gap Statistic…
2008
Abstract Background Inferring cluster structure in microarray datasets is a fundamental task for the so-called -omic sciences. It is also a fundamental question in Statistics, Data Analysis and Classification, in particular with regard to the prediction of the number of clusters in a dataset, usually established via internal validation measures. Despite the wealth of internal measures available in the literature, new ones have been recently proposed, some of them specifically for microarray data. Results We consider five such measures: Clest, Consensus (Consensus Clustering), FOM (Figure of Merit), Gap (Gap Statistics) and ME (Model Explorer), in addition to the classic WCSS (Within Cluster…
