Full textIncludes bibliographical references (p. 161-163).
Robust parameter design is an engineering methodology intended as a cost effective approach to improve the quality of products, processes and systems. Control factors are those system parameters that can be easily controlled and manipulated. Noise factors are those system parameters that are difficult and/or costly to control and are presumed uncontrollable. Robust parameter design involves choosing optimal levels of the controllable factors in order to obtain a target or optimal response with minimal variation. Noise factors bring variability into the system, thus affecting the response. The aim is to properly choose the levels of control factors so that the process is robust or insensitive to the variation caused by noise factors. Robust parameter design methods are used to make systems more reliable and robust to incoming variations in environmental effects, manufacturing processes and customer usage patterns. However, robust design can become expensive, time consuming, and/or resource intensive. Thus research that makes robust design less resource intensive and requires less number of experimental runs is of great value. Robust design methodology can be expressed as multi-response optimization problem.
(cont.) The objective functions of the problem being: maximizing reliability and robustness of systems, minimizing the information and/or resources required for robust design methodology, and minimizing the number of experimental runs needed. This thesis discusses various noise factor strategies which aim to reduce number of experimental runs needed to improve quality of system. Compound Noise and Take-The-Best-Few Noise Factors Strategy are such noise factor strategies which reduce experimental effort needed to improve reliability of systems. Compound Noise is made by combing all the different noise factors together, irrespective of the number of noise factors. But such a noise strategy works only for the systems which show effect sparsity. To apply the Take-The-Best-Few Noise Factors Strategy most important noise factors in system's noise factor space are found. Noise factors having significant impact on system response variation are considered important. Once the important noise factors are identified, they are kept independent in the noise factor array. By selecting the few most important noise factors for a given system, run size of experiment is minimized.
(cont.) Take-The-Best-Few Noise Factors Strategy is very effective for all kinds of systems irrespective of their effect sparsity. Generally Take-The-Best-Few Noise Factors Strategy achieves nearly 80% of the possible improvement for all systems. This thesis also tries to find the influence of correlation and variance of induced noise on quality of system. For systems that do not contain any significant three-factor interactions correlation among noise factors can be neglected. Hence amount of information needed to improve the quality of systems is reduced.

Full textThe main objective of this dissertation is to perform a Comparative Analysis of different Multicriteria Decision Making Methods applied to real-world problems, in order to produce relevant information to enable the incorporation of those methods on computational platforms. The current document presents a simple case study concerning a decision support application targeted for a real problem regarding retrofitting alternatives of a building with energy efficiency impact. The application process was started with the selection of two Multicriteria Decision Making Methods guided by a preexisting framework, and resulted in the choice of AHP and PROMETHEE II methodologies. These two methods were then combined with three different decision maker profiles (Conservative, Moderate and Aggressive) created by means of risk assessment profiling techniques for portfolio allocation. Afterwards, the chosen decision criteria were disposed in a Risk Pyramid according to their inherent level of risk regarding project evaluation. A match was then performed between the decision maker profiles and each criterion, so as to define a proper set of weights for the decision criteria and preference functions, with corresponding preference and indifference thresholds. Finally, three different sets of results (one for each decision maker profile) were produced using appropriate software, and a Sensitivity Analysis was performed over the criteria to understand their influence on the solution. The general conclusion of this Comparative Analysis is that the increase in the preference modelling ability of the methods brings up the least expected alternatives as recommendations for the decision maker. Besides, we have concluded that the decision profiles that allocate bigger weights to the riskiest criteria are the ones that produce the more dispersed set of results within each method application and within each decision maker profile.

Full textLarge scale approaches, namely proteomics and transcriptomics, will play the most important role of the so-called post-genomics. These approaches allow experiments to measure the expression of thousands of genes from a cell in distinct time points. The analysis of this data can allow the the understanding of gene function and gene regulatory networks (Eisen et al., 1998). There has been a great deal of work on the computational analysis of gene expression time series, in which distinct data sets of gene expression, clustering techniques and proximity indices are used. However, the focus of most of these works are on biological results. Cluster validation has been applied in few works, but emphasis was given on the evaluation of the proposed validation methodologies (Azuaje, 2002; Lubovac et al., 2001; Yeung et al., 2001; Zhu & Zhang, 2000). As a result, there are few guidelines obtained by validity studies on which clustering methods or proximity indices are more suitable for the analysis of data from gene expression time series. Thus, this work performs a data driven comparative study of clustering methods and proximity indices used in the analysis of gene expression time series (or time courses). Five clustering methods encountered in the literature of gene expression analysis are compared: agglomerative hierarchical clustering, CLICK, dynamical clustering, k-means and self-organizing maps. In terms of proximity indices, versions of three indices are analysed: Euclidean distance, angular separation and Pearson correlation. In order to evaluate the methods, a k-fold cross-validation procedure adapted to unsupervised methods is applied. The accuracy of the results is assessed by the comparison of the partitions obtained in these experiments with gene annotation, such as protein function and series classification

Full textLa globalización no es solo una transformación del mundo económico sino también del espacio geográfico en su conjunto. Los territorios locales participan en esta transformación. Estudiar y comparar sus evoluciones nos puede ayudar a analizar tanto la globalización, en su construcción, en sus efectos y en sus límites, como la existencia de dinámicas sociales y políticas que no son globalizadas. La reflexión se fundamenta sobre casos estudiados en el Perú, en colaboración con otros investigadores franceses y peruanos.

Full textTämä tutkimus tarkastelee standardoitujen kuntotestien ohjeistusta mobiiliympäristössä. Tutkimuksen pääpaino oli selvittää voiko kuntotestit suorittaa oikeilla tekniikoilla mobiilisovelluksen avulla. Eri visuaalisia apukeinoja, ohjeistuksia ja mobiililaitteita arvioitiin ja vertailtiin käytettävyyden ja virheiden esiintymisen suhteen. My Energy Test -kuntotestisovelluksen prototyyppiä käytettiin 2 x 2 x 3 kohteiden välisessä käyttäjätutkimuksessa, jossa oli kokonaisuudessaan 72 osallistujaa. Tietoa kerättiin kyselyllä käyttäjätestauksen jälkeen sekä videokuvaamalla käyttäjätestejä. Kysely mittasi koettua käytettävyyttä, videotallenteet analysoitiin poikkeamien, eli virheiden, testien oikeista suoritustekniikoista varalta. Tutkimuksen päälöydökset osoittavat, että käytetyllä mobiililaitteella ei todettu olevan vaikutusta koettuun käytettävyyteen, mutta se vaikutti tehtyjen virheiden lukumäärään. Lisäksi todettiin, että ääni- ja tekstiohjeistuksen koetussa käytettävyydessä ei ollut eroa. Visuaalisella apukeinolla oli tilastollisesti merkittävä vaikutus koetun käytettävyyden tulokseen; video ja kuvasarja arvioitiin animaatiota paremmiksi. Vähimpien virheiden ja käytettävyyden paras yhdistelmä havaittiin, kun video tai kuvasarja yhdistettiin tekstiohjeistukseen. Tutkimuksen tulosten perusteella pääteltiin, että standardoituja kuntotestejä on mahdollista suorittaa riittävällä moitteettomuudella ilman ammattilaisohjaajaa

Full textTechnical systems of today are often complex and integrated. If a fault occurs, the consequences can be disastrous both for the system itself and its surroundings. To maintain the operation and the security it is necessary to have a surveillance system which can detect a fault in an early stage.
In this thesis two structural methods for fault isolation analysis are discussed. The result from the studied algorithms shows what fault isolation properties a diagnostic model is expected to have. If the isolability is not good enough, it also gives information on where further modelling needs to be done.
To base a comparison of the two structural analysis algorithms on, four criteria are defined concerning for example realizability of residuals and time complexity. One interesting part of the methods is how dynamic models are handled. It is shown how differential constraints can end up in differential cycles which implies calculatory problems and what effects structural differentiation has on a system.
The algorithms have been tested on an application from the research training network DAMADICS. The result shows how different types of input models in this case give the same result.
