Linear fusion of interrupted reports in cooperative spectrum sensing for cognitive radio networks

2015

Interrupted reporting has recently been introduced as an effective method to increase the energy efficiency of cooperative spectrum sensing schemes in cognitive radio networks. In this paper, joint optimization of the reporting and fusion phases in a cooperative sensing with interrupted reporting is considered. This optimization aims at finding the best weights used at the fusion center to construct a linear fusion of the received interrupted reports, jointly with Bernoulli distributions governing the statistical behavior of the interruptions. The problem is formulated by using the deflection criterion and as a nonconvex quadratic program which is then solved for a suboptimal solution, in a…

Synchronous R-NSGA-II: An Extended Preference-Based Evolutionary Algorithm for Multi-Objective Optimization

2015

Classical evolutionary multi-objective optimization algorithms aim at finding an approx- imation of the entire set of Pareto optimal solutions. By considering the preferences of a decision maker within evolutionary multi-objective optimization algorithms, it is possible to focus the search only on those parts of the Pareto front that satisfy his/her preferences. In this paper, an extended preference-based evolutionary algorithm has been proposed for solving multi-objective optimiza- tion problems. Here, concepts from an interactive synchronous NIMBUS method are borrowed and combined with the R-NSGA-II algorithm. The proposed synchronous R-NSGA-II algorithm uses preference information provid…

An intelligent learning support system

2017

Fast-growing technologies are shaping many aspects of societies. Educational systems, in general, are still rather traditional: learner applies for school or university, chooses the subject, takes the courses, and finally graduates. The problem is that labor markets are constantly changing and the needed professional skills might not match with the curriculum of the educational program. It might be that it is not even possible to learn a combination of desired skills within one educational organization. For example, there are only a few universities that can provide high-quality teaching in several different areas. Therefore, learners may have to study specific modules and units somewhere e…

Addressing Complexity in Science|Environment|Health Pedagogy

2019

This paper aims to discuss complexity as a key feature for understanding the role of science knowledge in environmental and health contexts—a central issue in Science|Environment|Health pedagogy. Complex systems are, in principle, not predictable. In different contexts, ephemeral mechanisms produce different, sometimes completely unexpected results. The art of decision-making in complex contexts is to take scientific knowledge into account but to interpret its meaning in terms of concrete complex contexts. This is illustrated by four empirical studies on Science|Environment|Health issues, presented midway through this paper. The findings underscore the importance of introducing complexity i…

Contents and functions of dramatizations in team decision making

2017

This study examines the contents and functions of dramatizations in natural team decision making. Theoretically, the study employs symbolic convergence theory to understand decision making as a complex phenomenon constructed in symbolic communication. Observational meeting data and thematic interview data from an autonomous team in Finland were analyzed. A fantasy theme analysis and an inductive, rhetorical discourse analysis revealed three rhetorical visions and seven functions of dramatizations in the team’s decision making. Visions represented social, righteous, and pragmatic master analogues. The functions of dramatizations were legitimizing independent and current decisions, reinforci…

超越宣告性模式和判决主义模式* ———麦考密克对“法律推理和法律理论”的重新思考

2019

This paper offers a diachronic reconstruction of MacCormick’s theory of law and legal argumentation: In particular，two related points will be highlighted in which the difference between the perspective upheld in Legal Reasoning and Legal Theory and the later writings is particularly marked． The ? rst point concerns MacCormick’s gradual break with legal positivism，and more speci? cally the thesis that the implicit pretension to justice of law proves legal positivism false in all its different versions． The second point concerns MacCormick’s acceptance of the one－right－answer thesis and the consequent thinning of the differences between MacCormick’s theory of legal reasoning and that of Ronal…

ISEBA – A Framework for IS Evolution Benefit Assessment

2005

Decisions regarding information system evolution strategy, including modernization or replacement, are economically significant. Selection of a proper method for analyzing potential options, acquisition of suitable metrics or follow-up data, and evaluation of the results are major challenges in the evolution strategy decision making. In order to address these challenges, a framework for Information System Evolution Benefit Assessment (ISEBA) was developed. ISEBA provides assistance in the selection of a benefit-evaluation method for the investment situation at hand. It is based on empirical research on industrial decision making and co-operation projects, and examination of existing researc…

Clean Agent Selection Approached by Fuzzy TOPSIS Decision-Making Method

2008

Abstract. It is well known that halons are ozone-depleting substances and their release into the atmosphere has contributed in the last decades to the reduction in the ozone layer. In consequence to the Montreal Protocol, an international agreement designed to gradually eliminate the use of such substances, fire protection industry researchers faced the challenge of finding effective solutions to replace halon extinguishers. This research aims to provide a method to support the decision maker in the selection of the most suitable extinguisher substance for a specific application. According to such framework, a set of quantitative and qualitative criteria has been established in the decision…
