A Feature Rich Distance-Based Many-Objective Visualisable Test Problem Generator
2019
In optimiser analysis and design it is informative to visualise how a search point/population moves through the design space over time. Visualisable distance-based many-objective optimisation problems have been developed whose design space is in two-dimensions with arbitrarily many objective dimensions. Previous work has shown how disconnected Pareto sets may be formed, how problems can be projected to and from arbitrarily many design dimensions, and how dominance resistant regions of design space may be defined. Most recently, a test suite has been proposed using distances to lines rather than points. However, active use of visualisable problems has been limited. This may be because the ty…
Unidirectional probabilistic direct control for deferrable loads
2014
International audience; The idea of harnessing the inherent flexibility in demand of many types of electric loads has been largely discussed in the last years for coping with the need to maintain the energy demand-supply balance. In particular, the fine tuning of the operation conditions of different thermostatic loads (such as air-conditioning, refrigerators, etc.) has appeared as the most natural solution for load control with minimal user discomfort. In this paper we focus on an alternative approach: deploying simple open-loop control strategies for deferrable loads with minimal communication overhead. The idea is to send a multicast control message to a group of users, on the basis of t…
Collaborative virtual environments in the year of the dragon
2000
Three suggestions are made for extensions from and to CVE's: awareness of others, multiple media, and scalability. Awareness of others and their activities is strongly desirable in all media and applications, not just in CVE's. Multiple media are not seriously catered for in existing CVE's, and a suitable architecture will precede popular applications. CVE's need to be scalable to greater numbers of people, and achieving this also has implications for greater flexibility and reconfigurability. With respect to awareness of others, we argue that the Web and most document handling applications are unaware of others in the workgroup or community, and this limits the ability to support real work…
Video sharing application for educational use: Usability and impacts of participation modes
2014
For the past few years, the use of video lectures in universities has been on the increase. Production of video lectures will bring flexibility that is needed for study and enable the utilization of pedagogical solutions based on new videos. On the other hand, applications for the sharing and use of lecture videos clearly designed for educational requirements are not available. This article introduces an application for the sharing and use of videos. The application was designed and implemented for educational purposes, and it has been in use already for two years. The article examines, with the help of a SUS survey, students' and lecturer's satisfaction with the application and its usabili…
Object Orientation and Conceptual Modeling
1993
The object oriented (OO) approach is very popular nowadays. It has proved to be a powerful and practical programming paradigm for the development of large and complex software systems, including database management systems (DBMS). Among its many benefits are significant improvements in modularity, reusability, flexibility, and extensibility. The database community has already taken advantage of the OO approach and produced a number of OO DBMSs, much faster than in the case of the previous generation of relational systems.
Incentive System Design Based on Accrual Accounting: A Summary and Analysis
2009
ABSTRACT: This paper provides a formal analysis on how to design accrual-based incentive systems so that a manager's and owner's interests are properly aligned. We introduce a general framework to summarize the literature, provide various extensions to it, and point to some of its limitations. We characterize the entire class of goal-congruent and preference-similar incentive systems when the owner has perfect as well as imperfect information about the manager's preferences. This allows us to show how compensation functions and performance measures are interrelated and to demonstrate what information should be incorporated into compensation functions and performance measures. We illustrate …
Behavior adaptation and selection.
2010
6 pages; The evolutionary approach to behavior is concerned with the evolutionary origin and adaptive function of behavioral traits. Like any other part of the phenotype, behavior can be shaped by natural selection to produce adaptations. However, behavior often shows large phenotypic variation and flexibility, and can be both – subject to selection and a major agent of selection. Therefore, the study of adaptation and evolution of behavior is a particularly complex one, involving a wide range of methodologies and techniques, including mathematical modeling, comparative methods, phenotypic engineering, quantitative genetics, genetic dissection, and artificial selection.
The extension of collective agreements in France, Portugal and Spain
2020
This article examines the role of extension provisions for collective agreements in France, Portugal and Spain, three countries that have faced pressure to introduce more flexibility in their employment regimes during recent economic crises. The article establishes the continuing importance of extension provisions for maintaining high bargaining coverage in all three countries and traces the origin of national differences in their evolution to the strategies of the various actors, governments, employers and trade unions, and the context in which they are operating. It also looks at the characteristics of the extension regulations themselves.Cet article examine le rôle des mécanismes d’exten…
Shell structure and the fluctuation of the nuclear density distribution
1984
We investigate the relation between the density-fluctuations in nuclei and their description by single-particle models, i.e. the shell model and the Hartree-Fock method; the question is whether every shell-structure necessarily leads to those fluctuations. We demonstrate the flexibility of the single-particle models by constructing a shell-model potential and an effective Hartree-Fock potential, respectively, which produce completely flat distributions without any density fluctuation; this means that “shell structure” is not sufficient an explanation for the fluctuations. Only the additional requirement that the dynamical features of nuclei are also met selects a subclass of “reasonable” po…
SmartCampus Project
2017
The aim of the SmartCampus project is to create an environment which enables high-quality, flexible and effective studying, both as traditional face-to-face and online. A focal result of the project is the CiNetCampus environment, developed in connection with the Master’s education in mathematical information technology. It increase flexibility in education with the help of video lectures and add interactivity to lecture videos. It was also possible to integrate other functionalities to the environment that are useful for teaching and studying. This paper focuses on the presentation of the CiNetCampus environment and the functionalities implemented for it. The paper also highlights the impa…
