Full textWhen large software product lines are engineered, a combined set of traditional techniques, such as inheritance, or design patterns, is likely to be used for implementing variability. In these techniques, the concept of feature, as a reusable unit, does not have a first-class representation at the implementation level. Further, an inappropriate choice of techniques becomes the source of variability inconsistencies between the domain and the implemented variabilities. In this thesis, we study the diversity of the majority of variability implementation techniques and provide a catalog that covers an enriched set of them. Then, we propose a framework to explicitly capture and model, in a fragmented way, the variability implemented by several combined techniques into technical variability models. These models use variation points and variants, with their logical relation and binding time, to abstract the implementation techniques. We show how to extend the framework to trace features with their respective implementation. In addition, we use this framework and provide a tooled approach to check the consistency of the implemented variability. Our method uses slicing to partially check the corresponding propositional formulas at the domain and implementation levels in case of 1–to–m mapping. It offers an early and automatic detection of inconsistencies. As validation, we report on the implementation in Scala of the framework as an internal domain specific language, and of the consistency checking method. These implementations have been applied on a real feature-rich system and on three product line case studies, showing the feasibility of the proposed contributions

Full textThis dissertation is devoted to the study of the variability of creativity evaluations, by focusing ontraining non-experts judges to enhance their expertise. In the theoretical part, various issues related tocreativity, judgment and variability are explored and provide hypotheses for the empirical part. Thefirst series of studies allows justifying the relevance of the application of a simplified model of creativityjudgment inspired by Besemer & O’Quin (1999) to the evaluation by non-experts judges of graphicproducts made by children. The rest of the empirical studies are devoted to the investigation of theeffect of the training on 1) the stability and 2) the expertise of creativity evaluations. The model ofcreative judgments provides the mechanism explaining the effect of the training on the stability andthe expertise of creativity evaluations, by emphasizing the mediating role of stability and expertise ofrelevant predictors evaluation (originality and elaboration) and of the integration function, by which thejudge combines predictors to make a creativity judgment. A final study allows studying the long-termeffect of the training. These results are discussed and future research and applications are suggested

It is well accepted within the episodic memory literature that successful memory retrieval is often driven by context cues. Specifically, the cues that are stored with the memory of the event. To develop a better understanding of how episodic memory works, we must understand how manipulating context cues changes memory performance. One way to investigate the effects of context manipulation is using encoding variability, which refers to the amount of variability (i.e., change) in context cues from one repetition of an item or event, to the next. Preliminary research in our lab (Diana, unpublished data) has found that increased encoding variability improves memory retrieval in a novel context, but it is unclear why this is the case. We proposed that the mental processing described by transfer-appropriate processing (TAP) – a principle stating that memory retrieval success is determined by the match, or overlap, between the mental processing at encoding (i.e., memory formation) and memory retrieval – determines the contextual cues that are stored with the memory at encoding. We hypothesized that encoding variability works even when TAP has already been achieved by matching the processing and cues at encoding to those at retrieval. Alternatively, we hypothesized that encoding variability works by specifically achieving TAP, so that encoding variability is only helpful when the encoding and retrieval contexts do not match. Results indicated partial support for the alternative hypothesis, suggesting that encoding variability works by achieving TAP. However, these results were not sufficiently conclusive, and it is likely that there are other mechanisms that allow for encoding variability to improve memory. This study establishes the groundwork for future work examining encoding variability and its effects on memory.

Full textThe use of geomaterials different from flint in Early and Middle Paleolithic. Economical technical and functional choices after the study of two sites : Sainte-Anne I (Haute-Loire, France) (MIS 5-7) and Notarchirico (Basilicata, Italy) (MIS 14-17).We tried to answer the question: has the variability of raw materials (from petrographical characteristics and morphological aspects) influenced prehistoric knappers during the production both in time and space? The creation and use of specific descriptive files for each category of objects allowed us to analyze the technical characteristics of the products and to select the variables that played a major role in the assessment of needs at the base of the lithic production. Critical analysis of the litho-stratigraphic contexts and consideration of technical, technological or chronological diversity allows to reconsider the paradigms underlying the differentiation of the techniques: products façonnage (double sided, ébauche), Levallois production system, discoid production system. These terms have for too long concealed the variability of the characters in Paleolithic lithic production. We have now to reconsider the purposes of lithic studies and to aim to decipher the plurality of individuals and palaeolithic societies behaviours
L’utilizzazione delle rocce diverse dalla selce nel Paleolitico antico e medio : scelte economiche, tecniche e funzionali, sulla base dello studio dei siti di Sainte-Anne I (Haute-Loire, France) (SIO 5-7) e di Notarchirico (Basilicata, Italia) (SIO 14-17).La questione principale alla quale abbiamo tentati di rispondere è la seguente: la variabilità delle materie prime (caratteristiche petrografiche e morfologia dei supporti) ha condizionato gli uomini preistorici durante la produzione nel tempo e nello spazio? La creazione e l’utilizzo di schede di analisi specifiche per ogni categoria di oggetti ci ha permesso di analizzare i caratteri tecnici specifici dei prodotti e di selezionare le variabili principali che hanno giocato un ruolo importante nella valutazione delle necessità alla base della produzione litica. L’analisi critica dei contesti lito-stratigrafici e la considerazione delle diversità tecnica, tecnologica o cronologica delle industrie permette di riconsiderare i paradigmi alla base della differenziazione delle tecniche: prodotti del façonnage bifacciale (bifacciale, ébauche), sistema di produzione Levallois, sistema di produzione Discoide. Questi termini hanno per troppo tempo celato la variabilità dei caratteri che durante il Paleolitico era necessario prendere in considerazione nella produzione litica. Adesso bisogna dare un nuovo indirizzo agli studi, indirizzandoli verso la presa di coscienza della pluralità dei comportamenti umani e delle società paleolitiche
Vo, Van Olivier. "Introduction of variability into pantograph-catenary dynamic simulations." Thesis, Paris, ENSAM, 2016. http://www.theses.fr/2016ENAM0021/document.
Full textIn railways, electrical current is generally collected by the train through a complex coupledmechanical system composed of a pantograph and a catenary. Dynamic phenomena that occur duringtheir interaction are still not fully understood. Furthermore, the system behaviour is sensitive to numerousparameters and thus highly variable. The first contribution of this thesis is a detailed analysis of thepantograph-catenary dynamic interaction separating phenomena due to the dynamic response of the pantographto the catenary geometry from wave propagations, reflections and transmissions that occur in thecatenary. The coincidence of frequencies or characteristic times is then shown to explain most variationsin the quantities of interest. Moreover, droppers surrounding the mast have been shown to be particularlyimportant in dynamic interaction. Ratio of wire impedances and sum of wave velocities also appeared tobe dimensioning quantities for catenary design. The second contribution was to reduce epistemic uncertaintylinked with model parameters such as catenary damping, contact stiffness and element size. Thefinal contribution was to use the model in a configuration with random parameters. An initial step was tostatistically characterise physical catenary parameters using available measurements. From this randommodel, ranking of uncertainties using Sobol indices on static and dynamic criteria was shown to be possible.An absence of correlation between geometric and dynamic criteria was also found, which has notableimplications for maintenance policies. The high number of sensitivity studies also gave the occasion tohighlight the maturity of simulation tool and propose directions for further work on design, maintenance orcertification of pantographs and catenaries
Velayudhan, Vikas. "TCAD study of interface traps-related variability in ultra-scaled MOSFETs." Doctoral thesis, Universitat Autònoma de Barcelona, 2016. http://hdl.handle.net/10803/400200.
Full textThe work developed in this thesis has focused on the analysis and study of the impact on the variability of ultra-scaled MOSFETs due to the number and spatial distribution of interfacial traps. In the study, the number of locations where traps were located were randomly varied, but the total charge in the entire device was always maintained constant. Initially 2D simulations of interfacial traps located along the channel of the transistor and its influence on Vth was analyzed. The analysis was started with the case of a single location, analyzing the influence of channel length and drain voltage, and the case of 2 and multiple locations were analyzed. Subsequently, the analysis was extended to 3D simulations, simulating interfacial traps distributed across the transistor. Finally, the effect of interfacial traps was analyzed not only on Vth but also on Ion. For a more realistic vison of the effect of interfacial traps variability on ultra-scaled MOSFET transistors, the study was extended to 3D simulations of a device WxL = 50nm x 20nm. The results showed that the location of traps along the channel has more influence than its position at the edge of the channel. In addition, when the case of two traps were considered, it was observed that if they were close together their influence is less than if they were sufficiently separated. The results were interpreted in terms of changes in the area of potential barrier created by the position of the traps. Devices were simulated with different number of locations at random positions and compared to the 2D results, a 'turn around' effect was observed in the dependence of Vth (mean value) and σVth. The initial increase in Vth was attributed to an increase in area of the effective barrier with the increase in the number of locations. The subsequent decrease observed in Vth with the increase in the number of locations was attributed to an increased likelihood of having traps very close to one another resulting in a decrease in the effective area of the barrier, along with the charge scaling at each location. It was also noted that σVth follows the Pelgrom’s law and that the width of the device plays a dominant role in this dependence. Furthermore, it has also been found that the spatial distribution of the traps affects the Ion. The results showed that the location of traps along the channel fundamentally influences Vth, while the distribution of traps channel along the width affects mostly Ion. These dependencies explain the asymmetries found in the Id-Vg characteristics of transistors. The work could be continued by analyzing the impact of distributions of traps in dynamic conditions, as in the mechanisms of RTN or BTI. The main applicability of the results of this thesis lies in the field of reliability of ultra-scaled MOSFETs. The contributions made in this thesis contribute to understand the effect of the number and the spatial distribution of interfacial traps that can arise with mechanisms such as Bias Temperature Instabilities (BTI), Hot Carrier Injection (HCI) or Random Telegraph Noise (RTN) that can reduce device reliability and result in the dispersion of the characteristics of MOSFETs.
