A family of experiments to generate graphical user interfaces from BPMN models with stereotypes
2021
Abstract Context: A significant gap separates Business Process Model and Notation (BPMN) models representing processes from the design of Graphical User Interfaces (GUIs). Objective: This paper reports on a family of experiments to validate a method to automatically generate GUIs from BPMN models using stereotypes complemented with UML class primitives, and transformation rules. Method: We conducted two replications (23 and 31 subjects respectively) in which we compared two methods to generate GUIs from BPMN models; one automatic (using Stereotyped BPMN models) and one manual (using Non-stereotyped BPMN models). The study focuses on comparing effort, accuracy, and satisfaction (in terms of …
Teaching and learning in consumer behavior: a class activity supporting real decision-making in cultural management
2010
Abstract Problem-based learning has been suggested as a useful tool to foster student-centered learning and increase student motivation. Students of Business Administration are not familiar with Research on Consumer Behavior, its contents and techniques, since this subject is traditionally linked to Psychology. In order to facilitate the teaching-learning process in this subject, this paper presents an application of problem-based learning in the context of Consumer Behavior. Results of this pilot experience are assessed under a qualitative and a quantitative basis. The evidence obtained allow us to conclude that this collaboration project enable students to obtain and to process informatio…
The function of contextual knowledge: A videotaped class session in France
2015
This paper concerns seeing; specifically, what should and what can be seen in a classroom situation in a progressive school in Paris. It focuses on a lesson given in a foreign cultural context and the possibility of documenting it and reconstructing it: first, as far as possible, unaffectedly and out of context, to achieve comparative and interpretative classroom research. The emphasis will be on the way the subject matter is set up and the role the learners assume. It will become apparent that technical recordings, which are helpful in allowing literal transcriptions and descriptions, tempt us into abandoning objectiveness, thereby overlooking certain facts and circumstances. Only contextu…
Duality theory for multi-marginal optimal transport with repulsive costs in metric spaces
2018
In this paper we extend the duality theory of the multi-marginal optimal transport problem for cost functions depending on a decreasing function of the distance (not necessarily bounded). This class of cost functions appears in the context of SCE Density Functional Theory introduced in "Strong-interaction limit of density-functional theory" by M. Seidl.
On a class of languages with holonomic generating functions
2017
We define a class of languages (RCM) obtained by considering Regular languages, linear Constraints on the number of occurrences of symbols and Morphisms. The class RCM presents some interesting closure properties, and contains languages with holonomic generating functions. As a matter of fact, RCM is related to one-way 1-reversal bounded k-counter machines and also to Parikh automata on letters. Indeed, RCM is contained in L-NFCM but not in L-DFCM, and strictly includes L-CPA. We conjecture that L-DFCM subset of RCM
Guaranteed error bounds and local indicators for adaptive solvers using stabilised space–time IgA approximations to parabolic problems
2019
Abstract The paper is concerned with space–time IgA approximations to parabolic initial–boundary value problems. We deduce guaranteed and fully computable error bounds adapted to special features of such type of approximations and investigate their efficiency. The derivation of error estimates is based on the analysis of the corresponding integral identity and exploits purely functional arguments in the maximal parabolic regularity setting. The estimates are valid for any approximation from the admissible (energy) class and do not contain mesh-dependent constants. They provide computable and fully guaranteed error bounds for the norms arising in stabilised space–time approximations. Further…
Generation of Certain Matrix Groups by Three Involutions, Two of Which Commute
1997
Ž . We say that a group is 2, 2 = 2 -generated if it can be generated by three involutions, two of which commute. The problem of determining Ž . which finite simple groups are 2, 2 = 2 -generated was posed by Mazurov w x in 1980 in the Kourovka notebook 3 . An answer to this problem, for some classes of finite simple groups, was given by Ya. N. Nuzhin, namely for w x Chevalley groups of rank 1 in 4 , for Chevalley groups over a field of w x characteristic 2 in 5 , and for the alternating groups and Chevalley groups w x of type A in 6 . In this paper we consider the problem in the more n general context of matrix groups over arbitrary, finitely generated, commutative rings. As a special case…
Discussion on “Experimental Deformation of Opalinus Clay at Elevated Temperature and Pressure Conditions: Mechanical Properties and the Influence of …
2021
AbstractThe testing procedure and results on saturated samples of Opalinus Clay in the work of Schuster et al. (Rock Mech Rock Eng https://doi.org/10.1007/s00603-021-02474-3, 2021) were conducted and presented using strain rates two to four orders of magnitudes higher than the rates needed to allow pore pressure equilibrium in the material, both in drained and undrained conditions. This leads to an erroneous estimation of the mechanical properties in saturated conditions. We discuss this aspect in the context of shale testing. We also discuss the effect of drying-induced fissuring on the mechanical properties of geomaterials tested in dry conditions.
Climate Classification and Division of China
1988
As far as a climate classification and division is concerned, China represents a great complexity and diversity due to the country’s vast territory and extremely complex landforms. In detail, three major climate-governing factors must be taken into consideration for the climate of China as such and for its division over space: (1) the geographical latitude, (2) the elevation above sea level and (3) the distance from the Pacific Ocean. Of particular importance for a climate regionalization of China is the country’s location on the southeastern corner of the Eurasian continent against the Pacific Ocean, which means that the nature of the surrounding regions varies from open oceans to compact …
ASCO-Update 2015 – Neuigkeiten vom 51. Meeting der American Society of Clinical Oncology/ASCO 2015
2016
The field of gastrointestinal oncology is rapidly developing, on the one hand through the identification of novel molecular targets and therapeutic principles, on the other hand through the establishment and improvement of multidisciplinary treatment strategies. The following manuscript summarizes the most important trial results of the ASCO Meeting 2015 for gastrointestinal cancers. Besides trials on perioperative treatment of esophageal-, pancreatic- and colon cancer, we will present impressive data on new therapeutic strategies such as immunotherapy in gastric-, liver and microsatellite instable colorectal cancer. The trials will be put into context by the authors.
