In the present paper, a model-based fault/attack tolerant scheme is proposed to cope with cyber-threats on Cyber-Physicals Systems. A common scheme based on observers is designed and a state feedback control based on an aperiodic event-triggered framework is given with control synthesis and condition on the switching time. Classical fault tolerant control with Bi-linear Matrix Inequality () approaches are used to achieve novel and better security strategy based on an event-triggered control implementation. The purpose of using the event-based implementation would be to reduce (limit) the total number of transmissions to only instances when the networked control system (NCS) needs attention. Simulation results on a real-time laboratory three tank system are given to show the attack-tolerant control ability despite data deception attacks on both actuators and sensors. A detection/isolation scheme based on residual observers bank is also proposed. [less ▲]

This paper historicizes “rigour”, discipline” and “systematic” as inventions of a certain rational spirit of Enlightenment that was radicalized during the 19th century. These terms acquired temporary value in a transition during the 19th century when a culture of research was established within a modern episteme. Beginning in the 20th century, this development was perceived as problematic, triggering criticism from philosophy and the arts, and even within the sciences. “Discipline”, “rigour” and “systematic” have changed meanings over time, and recent contributions from Digital Humanities are promising for a renewed critical debate about rigour in research. Both digital humanities and quantitative research deal with big data sets aimed at providing a large-scale analysis. However, unlike most quantitative research, digital humanities explore uncertainties as their main focus. Attention to the human-machine collaboration has led to more expansive thinking in scientific research. Digital humanities go further by advancing a metaperspective that deals with the material hermeneutics of data accumulation itself. [less ▲]

Objective: Impulsivity is a multifaceted construct known to play a crucial role in the development and maintenance of a wide range of problematic behaviors and psychological disorders in children. Method: In this study, we adapted the short French adult version of the UPPS-P Impulsive Behavior Scale for use with children (short UPPS-P-C) and tested its psychometric properties. Results: Confirmatory factor analyses conducted on a sample of 425 children (aged from 8 to 14 years) supported the five-factor structure of the scale. Additional analyses emphasized the good internal and test-retest reliability of the short UPPS-P-C. Furthermore, our results also revealed that lack of premeditation and urgency subscales were able to discriminate between children diagnosed with attention-deficit/hyperactivity disorder (ADHD) and their matched controls. Conclusion: These results suggest that the short UPPS-P-C may be considered as a promising time-saving tool to assess impulsivity traits in healthy children and in children with psychiatric disorders.

On a generic metric measured space, we introduce a notion of improved concentration of measure that takes into account the parallel enlargement of k distinct sets. We show that the k-th eigenvalues of the metric Laplacian gives exponential improved concentration with k sets. On compact Riemannian manifolds, this allows us to recover estimates on the eigenvalues of the Laplace-Beltrami operator in the spirit of an inequality of Chung, Grigor’yan & Yau, Upper bounds for eigenvalues of the discrete and continuous Laplace operators.

Jugendliche aus stationären Einrichtungen (z.B. Heime) sind häufig von der Chronifizierung einer psychischen Störung bedroht [Schmid, 2007]. Unter anderem aufgrund von Traumatisierungen sind externalisierende Verhaltensprobleme, z.B. wiederholter unangemessener Ärgerausdruck, festzustellen, die einen Behandlungserfolg in Frage stellen. Erforderlich ist es daher problematische Ärgerreaktionen von Jugendlichen zu thematisieren, und den Umgang mit Ärger zu verändern. In dieser Falldarstellung wird die Umsetzung eines 10-wöchigen kognitiv-verhaltenstherapeutischen Ärgerbewältigungstrainings [Schwenkmezger et al., 1999] bei einem fremdplatzierten verhaltensauffälligen Jugendlichen aufgezeigt [Steffgen et al., 2014]. Die eingesetzten testdiagnostischen Verfahren belegen, dass die Bereitschaft zu aggressiven Verhaltensweisen sowie des nach außen gerichteten Ärgerausdrucks reduziert, und die Ärgerkontrolle erhöht wurde. Insgesamt konnte die Wirksamkeit der programmgestützten Intervention am Einzelfall nachgewiesen werden. Jugendliche in der Heimunterbringung können somit durch die Teilnahme an einer Ärgerintervention Nutzen ziehen, indem sie lernen ihre Emotionsregulation zu optimieren, um dadurch ihre soziale Kompetenz zu erhöhen. Ihre gesellschaftliche Eingliederung ließe sich dadurch erleichtern. [less ▲]

Domain models are a useful vehicle for making the interpretation and elaboration of natural-language requirements more precise. Advances in natural language processing (NLP) have made it possible to automatically extract from requirements most of the information that is relevant to domain model construction. However, alongside the relevant information, NLP extracts from requirements a significant amount of information that is superfluous, i.e., not relevant to the domain model. Our objective in this article is to develop automated assistance for filtering the superfluous information extracted by NLP during domain model extraction. To this end, we devise an active-learning-based approach that iteratively learns from analysts’ feedback over the relevance and superfluousness of the extracted domain model elements, and uses this feedback to provide recommendations for filtering superfluous elements. We empirically evaluate our approach over three industrial case studies. Our results indicate that, once trained, our approach automatically detects an average of ≈ 45% of the superfluous elements with a precision of ≈ 96%. Since precision is very high, the automatic recommendations made by our approach are trustworthy. Consequently, analysts can dispose of a considerable fraction – nearly half – of the superfluous elements with minimal manual work. The results are particularly promising, as they should be considered in light of the non-negligible subjectivity that is inherently tied to the notion of relevance. [less ▲]

Context: Automatically generating test suites is intrinsically a multi-objective problem, as any of the testing targets (e.g, statements to execute or mutants to kill) is an objective on its own. Test suite generation has peculiarities that are quite different from other more regular optimisation problems. For example, given an existing test suite, one can add more tests to cover the remaining objectives. One would like the smallest number of small tests to cover as many objectives as possible, but that is a secondary goal compared to covering those targets in the first place. Furthermore, the amount of objectives in software testing can quickly become unmanageable, in the order of (tens/hundreds of) thousands, especially for system testing of industrial size systems. Objective: To overcome these issues, different techniques have been proposed, like for example the Whole Test Suite (WTS) approach and the Many-Objective Sorting Algorithm (MOSA). However, those techniques might not scale well to very large numbers of objectives and limited search budgets (a typical case in system testing). In this paper, we propose a novel algorithm, called Many Independent Objective (MIO) algorithm. This algorithm is designed and tailored based on the specific properties of test suite generation. Method: An empirical study was carried out for test suite generation on a series of artificial examples and seven RESTful API web services. The \evo system test generation tool was used, where MIO, MOSA, WTS and random search were compared. Results: The presented MIO algorithm resulted having the best overall performance, but was not the best on all problems. Conclusion: The novel presented MIO algorithm is a step forward in the automation of test suite generation for system testing. However, there are still properties of system testing that can be exploited to achieve even better results. [less ▲]

An important aim in software testing is constructing a test suite with high structural code coverage – that is, ensuring that most if not all of the code under test has been executed by the test cases comprising the test suite. Several search-based techniques have proved successful at automatically generating tests that achieve high coverage. However, despite the well-established arguments behind using evolutionary search algorithms (e.g., genetic algorithms) in preference to random search, it remains an open question whether the benefits can actually be observed in practice when generating unit test suites for object-oriented classes. In this paper, we report an empirical study on the effects of using evolutionary algorithms (including a genetic algorithm and chemical reaction optimization) to generate test suites, compared with generating test suites incrementally with random search. We apply the EVOSUITE unit test suite generator to 1,000 classes randomly selected from the SF110 corpus of open source projects. Surprisingly, the results show that the difference is much smaller than one might expect: While evolutionary search covers more branches of the type where standard fitness functions provide guidance, we observed that, in practice, the vast majority of branches do not provide any guidance to the search. These results suggest that, although evolutionary algorithms are more effective at covering complex branches, a random search may suffice to achieve high coverage of most object-oriented classes.

We consider the inventory decision of a retailer facing strategic customers. We develop a behavioral theory that accounts for reference dependence, which makes predictions on how the presence of strategic customers leverages retailer behavior. Specifically, the reference-dependent retailer shall decrease her order quantity when there are more strategic customers in the population. As such, the conventional pull-to-center bias for newsvendor is generalized, since the presence of strategic consumers may induce the retailer to pull her order further below the center even when the production cost is low. Furthermore, increasing proportion of strategic customers reduces the retailer's ordering bias under low cost, yet amplifies it when the cost is high. Our subsequent experiments find pull-below-center effect, validate the theoretical predictions, and establish the asymmetry of reference dependence with the estimated behavioral parameters. We also study extensions to our model and carry out robustness checks of our experimental results. [less ▲]
