This paper proposes a new tracking state estimator aimed at following some of the dynamics of the network state (bus voltage phasors) by a hybrid processing of SCADA and synchronized phasor measurements. The latter are assumed to be available in limited number. To avoid time skew effects, only the SCADA measurements received since the last execution of the estimator are processed. To ensure observability, estimated SCADA measurements are used as pseudo-measurements. The procedure includes a prediction, an innovation analysis and a correction step. The latter consists of solving a constrained least-squares optimization. The simulation results refer to a test system undergoing large disturbances, evolving to long-term voltage instability or stabilized by emergency control. The proposed method appears to satisfactorily track the overall network evolution, even during those severe conditions. [less ▲]

We investigate the implications of venture capital (VC) investor type (government or private) on the operating efficiency of a sample of 515 Belgian portfolio firms up to 3 years after the investment. We find that the government VC-backed firms display significant reductions in productivity. No significant differences in efficiency are found in firms backed by private VC compared with their non-VC-backed peers. Finally, significant reductions in efficiency exist in targets of government VC compared to their non-VC-backed peers. [less ▲]

Objectives - This review studies the concept of affective security in children living outside of their family environment by a brief exposition of its practical illustration in institution. We want to show that sufficient affective security can be achieved even in children institutionalized with major attachment difficulties. Method - We will first examine the original meaning of the concept by a theoretical review of its evolution over the years in the literature. Then, we will consider various questions concerning the legitimacy of institutionalization in link with affective security through a case analysis illustrating the issue. We will finally end by mentioning the main practical implications about the optimization of affective security in children institutionalized. Results - It is foremost by the predictable and expected daily acts posed by the professional caregivers in institution that the child may find sufficient affective security, generating emotional well-being and ultimately, an overall adequate development. Discussion – Children early separated from their family home to be placed in residential institution most often suffer from serious difficulties in terms of attachment to others. In this context, the institution has to deal with a specifically challenge: that is, to help the child to (re-)find sufficient internal security to allow him to grow on solid foundations. The institutional life which replaces family life primarily consists of an organizational structure that seeks to make child life as predictable as possible so that it has the necessary daily benchmarks to evolve adequately. Conclusion – In the everyday life in institution, the professionals struggling with children’s attachment disorders constantly try to achieve a right emotional-body balance through their psycho-educational practices with the child deprived of secure attachment strategies.

Simulating a power system with both transmission and distribution networks modeled in detail is a huge computational challenge. In this paper, a Schur-complement-based domain decomposition algorithm is proposed to provide accurate, detailed dynamic simulations of such systems. The simulation procedure is accelerated with the use of parallel programming techniques, taking advantage of the parallelization opportunities inherent to domain decomposition algorithms. The proposed algorithm is general, portable and scalable on inexpensive, shared-memory, multi-core machines. A large-scale test system is used for its performance evaluation. [less ▲]

Pourquoi et dans quelle mesure les montreurs de marionnettes liégeoises font-ils intervenir Tchantchès aux côtés des grands chevaliers médiévaux, dont les aventures constituent une part importante du répertoire liégeois ? Quels sont ses moyens d'action, mais également ses modes d'expression ? Divers registres de langue apparaissent au fil des spectacles ; quels sont ceux prêtés à notre héros ? Et surtout, ce rôle et cette langue ont-ils évolué au fil du temps ? C’est à ces quelques questions que nous tentons de répondre, en observant les différentes interventions de Tchantchès dans les réécritures des aventures des quatre fils Aymon, l’une des œuvres les plus anciennes et les plus fréquemment jouées dans les théâtres liégeois dévolus aux comédiens de bois.

Ce travail vise à interroger la manière dont les jeux vidéo et les dynamiques de détournement qu’ils suscitent chez les joueurs redéfinissent la traditionnelle opposition entre consommation et création. Dans ce but, nous étudierons un usage spécifique du médium vidéoludique qui s’est institué en véritable pratique créative sur internet : le speedrun (et son dérivé, le tool-assisted speedrun). L’analyse se déroulera en deux temps : une première partie envisagera les déplacements concrets qu’opère le speedrun dans les notions liées au pôle de la réception (qu’est-ce qu’être un joueur ou un spectateur au sein de ce domaine ?) ; la seconde étudiera la façon dont cette pratique participe à redéfinir le pôle de la production (que deviennent les notions d’auteur, d’œuvre et de création dans le cadre de cette activité ?).

Perception results from a combination of actual data and interpretative schemata based on pre-existing knowledge. Thus, ensuing subjective experience depends on the dynamic interplay between data-driven and conceptually-driven processing. A chronic imbalance between these two sources of stimulus encoding is likely to be maladaptive and could underlie cognitive and behavioral disturbances similar to that observed in schizotypy, especially if the balance is tipped too far towards conceptually-driven processing (i.e., Internal encoding style). This study aimed to examine the relationships between encoding style and various dimensions of schizotypy, by using a questionnaire that evaluates the extent to which pre-existing schemata (versus cues from the outside world) affect encoding processes. Consistent with previous findings, our results revealed that both Cognitive-Perceptual and Disorganization dimensions were related to an internal mode of encoding, suggesting that individuals with these features may be characterized by a disposition to biases at early stages of encoding.
