Implementing stochastic multicriteria acceptability analysis
Tervonen, Tommi; Lahdelma, RistoStochastic multicriteria acceptability analysis (SMAA) is a family of methods for aiding multicriteria group decision making in problems with inaccurate, uncertain, or missing information. These methods are based on exploring the weight space in order to describe the preferences that make each alternative the most preferred one, or that would give a certain rank for a specific alternative. The main results of t...
Image Analysis and Multiphase Bioreactors
Ferreira, E. C.; Mota, M.; Pons, M. N.The applications of visualisation and image analysis to bioreactors can be found in two main areas: the characterisation of biomass (fungi, bacteria, yeasts, animal and plant cells, etc), in terms of size, morphology and physiology, that is the far most developed, and the characterisation of the multiphase behaviour of the reactors (flow patterns, velocity fields, bubble size and shape distribution, foaming), t...
Information security policies: a content analysis
Lopes, Isabel Maria; Sá-Soares, FilipeAmong information security controls, the literature gives a central role to information security policies. However, there is a reduced number of empirical studies about the features and components of information security policies. This research aims to contribute to fill this gap. It presents a synthesis of the literature on information security policies content and it characterizes 25 City Councils information...
A Quantitative analysis of European Horses from Pleistocene to Holocene
Kaushik, NeelanshuEmbora se conheçam muitos artigos publicados sobrea anatomia e sistemática do cavalo do Quaternário,a história de alguns Equus mostra a falta de alguns elos de ligação na história natural do cavalo. No presente trabalho pretende‐se fazer uma tentativa de classificar Cavalos (discriminar entre espécies ou grupo de espécies), com base no tamanho, sexo e forma, com em dois métodos estatísticos. Os objectivos são...
Maple tools for modified quaternionic analysis
Falcão, M. I.; Malonek, H. R.; Silva, A. M.Since 1992 H. Leutwiler, S. L. Eriksson and others developed in a number of papers a modified Clifford analysis and, particularly, a modified quaternionic analysis. The modification mainly consists in considering generalized Cauchy-Riemann equations with respect to a hyperbolic metric in a half space. The aim of this paper is to show how through a change of the basic combinatorial relations used in the modified...
Code analysis : past and present
Cruz, Daniela da; Henriques, Pedro Rangel; Pinto, Jorge SousaThe integration of Software components within complex industrial applications with severe security standards, requires strict quality assessment of each integrated component. That is, requires a guarantee that each component is compliant with the software development good practices and all the standards in use. If full certification is easy to obtain for proprietary modules, it is particularly hard to achieve w...
Turbidimetric and nephelometric flow analysis$econcepts and applications
Morais, Inês P. A.; V. Tóth, Ildikó V.; O. S. S. Rangel, AntónioA review on flow analysis with turbidimetric and nephelometric detection is presented. A brief discussion of the principles of turbidimetry and nephelometry is given. Particular emphasis is devoted to coupling different flow techniques (flow injection, sequential injection, multicommutation) to these detection techniques. Applications in environmental, pharmaceutical, biological, and food samples are summarized...
The assessment of retailing efficiency using network data envelopment analysis
Vaz, Clara B.; Camanho, Ana; Guimarães, RuiAPDIO - Associação Portuguesa de Investigação Operacional e EURO ; This paper describes a method for the assessment of retail store performance based on DEA. The assessment considers the stores aggregate several subunits, corresponding to sections with management autonomy. This motivated an analysis at the section level and the store level. The performance assessment of the sections involves a comparison among...
Recursion patterns and time-analysis
Barbosa, Manuel Bernardo; Cunha, Alcino; Pinto, Jorge SousaThis paper explores some ideas concerning the time-analysis of functional programs defined by instantiating typical recursion patterns such as folds, unfolds, and hylomorphisms. The concepts in this paper are illustrated through a rich set of examples in the Haskell programming language. We concentrate on unfolds and folds (also known as anamorphisms and catamorphisms respectively) of recursively defined types,...
Comparative Efficiency Analysis of Referral Costs in
Portela, Maria; Thanassoulis, Emmanuel; Graveney, MikeThe aim of this paper is to compare English General Practitioner (GP) units in terms of their overall referral costs through Data Envelopment Analysis (DEA). Results revealed potential cost savings and benchmark practices under 4 perspectives: ‘overall cost efficiency’, ‘technical efficiency’, ‘allocative efficiency’, and ‘price efficiency’.
