Increasing the Museum Value of Information Technology Objects
2009
In this article, we define the basic concepts of museum work, museum value, and contextual information with the help of a case study and literature. We base the case study on the empirical material of a project that aimed to gather knowledge of the collections of the Finnish Data Processing Museum Association. This article opens up the concepts and analyzes them in the context of museum work and information technology objects.
How Do Students Value the Importance of Twenty-first Century Skills?
2014
Frameworks of twenty-first century skills have attained a central role in school development and curriculum changes all over the world. There is a common understanding of the need for meta-skills such as problem solving, reasoning, collaboration, and self-regulation. This article presents results from a Finnish study, in which 718 school pupils aged 11 to 15 years were asked to anticipate the skills they would need in the future. Accordingly, they were asked to value and rank the twenty-first century skills listed in existing frameworks and pick out those they regarded as the most important they had learned. Social skills and collaboration were ranked highest, both in the listed frameworks …
ISTehnology - Metamodel based approach to information system development
2014
Document describes experience of using metamodel-based tool ISTehnology in development of information systems. The author of this document is one of the developers of ISTehnology. The main goal of the research is to figure out the framework (methodology and tools) for building information systems able to work in variable business environment and easy changeable. ISTechnology is such a framework. The document describes a metamodel of ISTehnology, approach to information systems development, advantages and disadvantages of its usage and possibilities to prevent disadvantages by using modern graphical tools of modeling.
Fuzzy dynamic sliding mode control design for high order disturbed systems
2013
In this paper, the problem of fuzzy dynamic sliding mode control design is investigated for a class of disturbed systems. Specifically, the fuzzy controller is constructed based on one feedback signal to estimate the unknown nonlinear terms and to develop the sliding mode control according to the fuzzy rules. Furthermore, it possesses the characteristic of simplicity in design and effectiveness in attenuating chattering. Finally, a numerical example is included to demonstrate the effectiveness and advantage of the proposed method.
Comparing Traditional and IRT Scoring of Forced-Choice Tests.
2018
This article explores how traditional scores obtained from different forced-choice (FC) formats relate to their true scores and item response theory (IRT) estimates. Three FC formats are considered from a block of items, and respondents are asked to (a) pick the item that describes them most (PICK), (b) choose the two items that describe them the most and the least (MOLE), or (c) rank all the items in the order of their descriptiveness of the respondents (RANK). The multi-unidimensional pairwise-preference (MUPP) model, which is extended to more than two items per block and different FC formats, is applied to obtain the responses to each item block. Traditional and IRT (i.e., expected a po…
Vascular Contraction Model Based on Multi-agent Systems
2017
This paper presents a first approximation to the simulation of vascular smooth muscle cell following an agent-based simulation approach. This simulation incorporates mathematical models that describe the behaviour of these cells, which are used by the agents in order to emulate vascular contraction. A first tool, implemented in Netlogo, is provided to allow the performance of the proposed simulation.
Dual Inequalities for Stabilized Column Generation Revisited
2014
Column generation (CG) models have several advantages over compact formulations: they provide better linear program bounds, may eliminate symmetry, and can hide nonlinearities in their subproblems. However, users also encounter drawbacks in the form of slow convergence, also known as the tailing-off effect, and the oscillation of the dual variables. Among different alternatives for stabilizing the CG process, Ben Amor et al. [Ben Amor H, Desrosiers J, Valério de Carvalho JM (2006) Dual-optimal inequalities for stabilized column generation. Oper. Res. 54(3):454–463] suggest the use of dual-optimal inequalities (DOIs) in the context of cutting stock and bin packing problems. We generalize th…
Skeletons for parallel image processing: an overview of the SKiPPER project
2002
International audience; This paper is a general overview of the SKIPPER project, run at Blaise Pascal University between 1996 and 2002. The main goal of the SKIPPER project was to demonstrate the appli- cability of skeleton-based parallel programming techniques to the fast prototyping of reactive vision applications. This project has produced several versions of a full-fledged integrated pa- rallel programming environment (PPE). These PPEs have been used to implement realistic vi- sion applications, such as road following or vehicle tracking for assisted driving, on embedded parallel platforms embarked on semi-autonomous vehicles. All versions of SKIPPER share a common front-end and reperto…
Market Polarization due to Difference in Interface Implementation Efforts
2009
Another factor potentially affecting the evolution of the OSS/BSS software market is the high complexity of software interfaces. The software provided to a customer – a CSP – needs to be integrated with a number of heterogeneous subsystems deployed by the customer. If the number of integration interfaces is high, a vast amount of special knowledge is needed in the vendor organization. High integration efforts also take up the time of the compentent employees of the vendor organization, thereby reducing the number of customers which it is capable of serving. As a result, only few large vendors can compete in such market, and, due to a lack of competition, the evolution towards a horizontaliz…
Systematic classification of two-loop realizations of the Weinberg operator
2015
We systematically analyze the $d=5$ Weinberg operator at 2-loop order. Using a diagrammatic approach, we identify two different interesting categories of neutrino mass models: (i) Genuine 2-loop models for which both, tree-level and 1-loop contributions, are guaranteed to be absent. And (ii) finite 2-loop diagrams, which correspond to the 1-loop generation of some particular vertex appearing in a given 1-loop neutrino mass model, thus being effectively 2-loop. From the large list of all possible 2-loop diagrams, the vast majority are infinite corrections to lower order neutrino mass models and only a moderately small number of diagrams fall into these two interesting classes. Moreover, all …
