Test-driven development in education
2008
Test-Driven Development (TDD) was applied in educational setting right after it became well-known as a key practice of Extreme Programming (XP). Basically, there are many studies reporting positive experiences on TDD applied in different levels of a curriculum. In this paper, we discuss the role of TDD in education through the students' experiences. In our experiment, a challenging programming task was applied in order to see what kind of difficulties the students would encounter and discuss. The students' answers revealed several topics that require a careful treatment in teaching to avoid conceptual confusion. For example, the topics include the scalability of TDD, extent of single test, …
Organizational Culture Challenges of Adopting Big Data: A Systematic Literature Review
2019
Part 2: Big Data Analytics; International audience; The interest of adopting big data (BD) in organizations has emerged in recent years. Even though many organizations have attempted to adopt BD, the benefits gained by this investment has been limited, and organizations struggle to fully utilize the potential of BD. There has been done several studies on the different challenges and benefits that may occur during the process of adopting and using BD. One major factor that has been discussed in the literature to overcome such challenges has been organizational culture. This paper aims to provide a systematic literature review that reports the organizational culture’s impact on BD adoption th…
Knowledge-driven multi-agent simulation engineering for assessing the effectiveness of disaster management plans
2020
Protecting humans from disasters has been an active mission of governments and experts through the definition of disaster management plans. Defining disaster response strategies is crucial in order to reduce the number of victims and the economic impact. In order to select which response plan is best suited to a specific disaster situation, these plans must be evaluated. However, such evaluation is limited by the high cost of exercises and the specificity of existing simulation models. The approach defended in this thesis combines techniques from Semantic Web and multi-agent simulation to evaluate disaster management response plans. It is composed of four steps : (1) modeling disaster manag…
Investigation of applicability of alanine pellets and films for dosimetry of proton clinical beams
2015
Laser-driven proton has recently gained a great interest as an alternative to conventional and more expensive acceleration techniques. These ion beams have desirable qualities such as small source size, high luminosity and small emittance to be used in different physics fields. This is very promising specially for the future perspective of a new concept of hadrontherapy based on laser-based devices could be developed, replacing traditional accelerating machines. ELIMED (Medical Applications at Extreme Light Infrastructure) is a task-force originally born by an idea of ELI-Beams (Prague) and INFN-LNS (Italian Institute for Nuclear Physics of Catania) researchers. ELIMED main goal is to perfo…
How Idioms Are Recognized when Individuals Are “Thrown Off the Track”, “Off the Rack” or “Off the Path”: A Decision Time Experiment in Healthy Volunt…
2021
Figurative elements in language have their own particularities, including words that deviate from their generally accepted definition to amplify our language or to paraphrase an issue. It is still unclear how individuals process idioms that are figurative or ambiguous, especially when they additionally become distracted by modified idioms that are similar in appearance. In our study, 47 healthy adults (mean age of 27.3 years, SD = 2.9) participated in a decision time experiment to determine how participants recognize well-formed, genuine German idioms alongside certain idiom modifications. All participants were initially exposed to a prime on a screen. Then, they had to detect the target id…
Understanding dynamic scenes
2000
We propose a framework for the representation of visual knowledge in a robotic agent, with special attention to the understanding of dynamic scenes. According to our approach, understanding involves the generation of a high level, declarative description of the perceived world. Developing such a description requires both bottom-up, data driven processes that associate symbolic knowledge representation structures with the data coming out of a vision system, and top-down processes in which high level, symbolic information is in its turn employed to drive and further refine the interpretation of a scene. On the one hand, the computer vision community approached this problem in terms of 2D/3D s…
The magnetohydrodynamic force experienced by spherical iron particles in liquid metal
2016
Abstract The paper contains a theoretical investigation of magnetohydrodynamic force experienced by iron particles (well-conducting and ferromagnetic) in well-conducting liquid. The investigation is performed by extending the Leenov and Kolin's theory to take into account the second-order effect. Therefore, the limits of the parent model are taken over to the present results. It is found that the effective conductivity of iron particles in liquid metal, which is important for practical application of the theoretically obtained force, is approximately equal to 1.5·106 S/m. The last result is obtained using a quasi-empirical approach – a comparison of experimental results with the results of …
The Death of the Subject in David Lynch's Lost Highway and Mulholland Drive
2003
International audience; Quel est le sujet de ces deux films qui ont suscité de nombreuses interrogations auprès du public lors de leur sortie, questions portant notamment sur la signification de la diégèse ? Nous avançons que ce n'est pas à ce niveau-là que l'on doit chercher le sens des films de Lynch. En fait, la mort du personnage comme sujet va de pair avec l'absence d'une histoire ; l'évolution du cinéma de Lynch montre que, si sujet il y a, c'est du côté du spectateur qui tient désormais le rôle de l'enquêteur que tenait les personnages dans les œuvres antérieures (Blue Velvet et la série Twin Peaks). Le sujet lynchien apparaît alors un véritable objet dans une composition qui se refl…
Driver mutations and differential sensitivity to targeted therapies: a new approach to the treatment of lung adenocarcinoma
2010
The adenocarcinoma of the lung has recently shown peculiar molecular characteristics, which relate with both carcinogenesis and response to targeted drugs. Several molecular alterations have been defined as "driver mutations". These are responsible for both the initiation and maintenance of the malignancy. The epidermal growth factor receptor (EGFR) pathway is the main regulator of cell function and cancer development. It has a widely defined role in the occurrence of driver mutations. Up till now EGFR gene mutations, KRAS gene mutations and EML4-ALK fusion genes are the most widely recognized alterations involved in both the biology and the clinical management of lung adenocarcinoma. In th…
Major results from the first plasma campaign of the Wendelstein 7-X stellarator
2017
After completing the main construction phase of Wendelstein 7-X (W7-X) and successfully commissioning the device, first plasma operation started at the end of 2015. Integral commissioning of plasma start-up and operation using electron cyclotron resonance heating (ECRH) and an extensive set of plasma diagnostics have been completed, allowing initial physics studies during the first operational campaign. Both in helium and hydrogen, plasma breakdown was easily achieved. Gaining experience with plasma vessel conditioning, discharge lengths could be extended gradually. Eventually, discharges lasted up to 6 s, reaching an injected energy of 4 MJ, which is twice the limit originally agreed for t…
