Current characterisation for ultra low power wireless body area networks

2010

The emerging area of body area networks (BAN) imposes challenging requirements on hardware and software to achieve the desired lifetimes for certain devices such as long term medical implants. In this paper, we propose a novel approach to the measurement and characterisation of the energy consumption of BAN devices. The approach uses a low cost energy auditing circuit and addresses the problem of accurately measuring low-level current consumption. This new technique will allow precise and analytical measurements of systems and components in terms of energy. This will help circuit designers minimise power consumption in BAN devices. Software engineers might use this approach to validate and …

Characterization of petroleum-based products by infrared spectroscopy and chemometrics

2012

Abstract The role of fossil fuels in providing the energy required for automobiles, factories and daily life has seriously concerned the authorities. Consistency of the quality of petroleum-based products is an important aspect of social and environmental criteria in a developed society. High-quality petroleum-based fuels would have several benefits (e.g., reduction in rate of consumption, less environmental pollution and durability of hardware). We review recent advances in the application of infrared spectroscopy in the petroleum industry. We focus on the methods proposed for the determination of a wide range of characteristics in petroleum-based products. We discuss methods based on the …

Multi-dimensional pattern matching with dimensional wildcards

1995

We introduce a new multi-dimensional pattern matching problem, which is a natural generalization of the on-line search in string matching. We are given a text matrix A[1: n1, ..., 1:n d ] of size N= n1×n2×...×n d , which we may preprocess. Then, we are given, online, an r-dimensional pattern matrix B[1:m1,...,1:m r ] of size M= m1×m2×...×m r , with 1≤r≤d. We would like to know whether B*=B*[*, 1:m1,*, ...,1: mr, *] occurs in A, where * is a dimensional wildcard such that B* is any d-dimensional matrix having size 1 × ... × m1×...1×m r ×...1 and containing the same elements as B. Notice that there might be (d/r)≤2d occurrences of B* for each position of A. We give CRCW-PRAM algorithms for pr…

Spatial dispersion intensity measure of phase concentration distributions and its applications to quantitative characterization, distinguishing and c…

2008

A method of evaluation of spatial dispersion of structures is presented. A quantitative parameter measuring spatial dispersion is introduced. It is shown that this parameter indeed measures spatial dispersion. A classification of bubble flow structures based on values of this parameter is proposed. An example of application of the method to real flow structures is presented.

Joint Audit: Issues and Challenges for Researchers and Policy-Makers

2013

International audience; The publication of the European Commission Green Paper, ‘Audit Policy: Lessons from the Crisis’ in October 2010, has stirred up a lively debate on the role of joint audits. This literature review identifies and evaluates, for the benefit of future research and regulators, existing evidence about joint audits. We find limited empirical support to suggest that joint audits lead to increased audit quality, but some empirical support to suggest that joint audits lead to additional costs. Overall, this paper indicates that joint audit should be seen as a mechanism that is embedded in a broader institutional context and not be considered in isolation from other factors tha…

The character and origin of the manuscripts in the present edition

1995

In the following I try to provide the reader with all the details needed to insert the Godel essays appearing here in the broader context of the rest of his unpublished work, as well as everything about my personal work on them. I start with a short description of what can be found in the Godel Nachlass in Princeton, USA, by referring to the catalogue prepared by John Dawson. Then I attempt to justify the particular selection I made of the manuscripts which I finally decided to study, reconstruct and publish. Such an explanation seems to be advisable given the great amount of Godel’s material unpublished but still extant. Also, I describe some of the historical details relevant to understan…

Characterization of a digital camera as an absolute tristimulus colorimeter

2003

An algorithm is proposed for the spectral and colorimetric characterization of digital still cameras (DSC) which allows them to be used as tele-colorimeters with CIE-XYZ color output, in cd/m2. The spectral characterization consists in the calculation of the color-matching functions from the previously measured spectral sensitivities. The colorimetric characterization consists in trans- forming the raw RGB digital data into absolute tristimulus values CIE-XYZ (in cd/m2) under variable and unknown spectroradiometric conditions. Thus, in the first stage, a gray balance was applied over the raw RGB digital data to convert them into RGB relative colorimetric values. In the second stage, an algo…

Sport and Quality of Life

2022

Negli ultimi trent’anni lo sport ha assunto un significato molto rilevante nella vita delle persone e, seppure con notevoli differenze, sia nei paesi a sviluppo economico avanzato, sia in quelli in via di sviluppo. A livello individuale, esso ha costituito un’area di investimento identitario quando ha assunto la forma di sport spettacolo del quale fruire, alimentando la pratica del tifo e il fandom o costituendo il modello di uno stile di vita vincente; ma anche quando ha assunto la forma di pratica del tempo libero attraverso la quale tenersi in forma, facendo crescere, in questo caso, la diffusione di una cultura della salute e del benessere. Si tratta di due modalità di approcciare al co…

but also when he took the form of free time practice through which to keep fit making grow in this case the diffusion of a culture of health and well-being. These are two ways of approaching the consumption of sports by spectators and actorIn the last thirty years sport has taken on a very significant meaning in people's lives and albeit with considerable differences both in advanced economic development countries and in developing countries. On an individual level it constituted an area of identity investment when it assumed the shape of “sport spectacle” to be enjoyed fueling the practice of cheering and fandom or constituting the model of a winning lifestyleand the two ways of use can be strongly related to the perception and assessment of the quality of life. The “semantic universes” which however connote sport and “free time sports” have often appeared polarized. Commercial sport and sports professionalism are intertwined with the institutions of economics politics and culture which above all stress its “spectacularity” in order to capture first and foremost the audience. But also the sport of leisure time is intertwined with the actions of the institutions of economics politics and culture with the difference that these stress above all its “healthy value” aimed at the “healthy and rational” investment of time in an activity which improves the quality of life in the short medium and long period. This polarization between the consumption of sport entertainment - commercial sport - and the consumption of sport as a leisure activity - sport for all - has become increasingly interconnected precisely because of the increased collective identity demand via sport. In other words we have witnessed the spread of shape of sports entertainment that recall the importance of sports for psychophysical well-being for integration and social participation for the reduction of social inequalities ethnic and cultural differences and in which the importance assumed was weakened in the show from agonism from competition from the physical confrontation between two contenders or two teams. A sport in which we act with competitors as well as against competitors. And on the other hand we have gradually witnessed the spectacularization of sports in our free time to the point that the sharing of the results obtained through the declination of a competitive spirit that presents itself as directed no longer against other contenders but against its own performance limits it has become the way in which each person makes part of his or her own life spectacular the one he often considers most authentic. The aim of this work is to describe how the intertwining between the commercial/professional dimension of the sports show and the playful/recreational dimension of sports practice are fueled by a demand and an offer of social identity that characterizes these two “semantic universes”.Settore SPS/07 - Sociologia Generale

Characterisation through naming in Javier Marias’ A Heart so White (1992): A corpus stylistic analysis

2020

espanolCorazon tan blanco (1992), una muy conocida obra de Javier Marias, ha dado lugar a numerosos estudios. Sin embargo, ninguno de ellos se ha interesado en interpretar estilisticamente el conjunto de formas denominativas y su funcion pragmatica en la caracterizacion de los personajes de la obra. La presente contribucion presta atencion a dicho objetivo. Para ello haremos uso de la estilistica de corpus, la cual aplica tecnicas desarrolladas por la linguistica de corpus al analisis literario. El uso de dicha metodologia nos ha permitido ser sistematicos y exhaustivos en el analisis cuantitativo e interpretar cualitativamente las elecciones denominativas de Marias como elementos important…
