Does relevance matter to data mining research?
2008
Data mining (DM) and knowledge discovery are intelligent tools that help to accumulate and process data and make use of it. We review several existing frameworks for DM research that originate from different paradigms. These DM frameworks mainly address various DM algorithms for the different steps of the DM process. Recent research has shown that many real-world problems require integration of several DM algorithms from different paradigms in order to produce a better solution elevating the importance of practice-oriented aspects also in DM research. In this chapter we strongly emphasize that DM research should also take into account the relevance of research, not only the rigor of it. Und…
Kromos: Ontology based information management for ICT societies
2009
Over the last few years, several projects for the development of innovative systems capable of collecting and sharing information have been carried out, following the increasing companies' interest on a correct knowledge management. ICT companies' managers have realized that knowledge and its management, more than the mere data, constitute fundamental part of their activities. This paper proposes a Knowledge Management System whose main feature is an underlying ontological knowledge representation. This data representation allows the specialization of the reasoning capabilities and the provision of ad hoc behaviors. The system has been designed for the management of projects and processes a…
Applying constructivist approach to educational business games: Case REALGAME
2003
Business organizations and their employees face ever-increasing complexity and accelerating changes. This brings along the need for training models that can transmit knowledge and skills needed in this kind of environment. Business process understanding is especially required. This article evaluates business games in the light of constructivism, a view of learning emphasizing the need to anchor training to everyday activities and concrete contexts, and introduces a new computer-based business game. The purpose of this construction is to give the business game participants a realistic view of business processes and thus enhance participant business process perception. The primary aim of the…
Business models and opportunity creation: How IT entrepreneurs create and develop business models under uncertainty
2015
How can entrepreneurs develop business models for markets in which the technology is constantly changing-or create business models for markets that do not exist? These are fundamental questions for information technology IT entrepreneurs, and for information systems IS scholars who seek to develop a theoretical understanding of business models. The case study presented in this paper addressed these questions, demonstrating how a small software firm developed its business model over a 15-year period in cloud gaming markets. Based on the empirical findings, a preliminary theoretical model is presented. The aim of the model is to increase scholarly understanding of how business models are crea…
Translating the Idea of the eGovernment One-Stop-Shop in Indonesia
2013
Article from the Book:Information and Communication Technology, Springer 2013. Also available on SpringerLink:http://dx.doi.org/10.1007/978-3-642-36818-9_1 This study aims to understand how the idea of an eGovernment one- stop-shop (OSS) has been translated into a new setting. Since the beginning of 2000, this idea has been implemented in a variety of ways by Indonesian local governments. Using an interpretive case study in the city of Yogyakarta, the study revealed that the specificity of each setting influences the translation process of the idea of OSS during its institutionalization. It also identified a set of editing rules used during the translation process. These include the editing…
Analysis and validation in design time of distributed control systems implemented by means of rule based expert systems
2005
In this paper a new analytical method for control systems validation is presented. The control system will be implemented by means of expert systems based on rule nets, which are a formalism that seeks to express an automatism in a similar way to as would make it a human being: "IF antecedents THEN consequent". But at the same time rule nets are a tool for the design, analysis and implementation of rule based systems (RBS), and consist on a mathematic-logical structure which analytically reflects the set of rules that the human expert has designed. The validation consist on the analysis of the decisive rule nets properties in design time. This properties have been studied and formalized com…
The Duality of Entropy/Extropy, and Completion of the Kullback Information Complex
2018
The refinement axiom for entropy has been provocative in providing foundations of information theory, recognised as thoughtworthy in the writings of both Shannon and Jaynes. A resolution to their concerns has been provided recently by the discovery that the entropy measure of a probability distribution has a dual measure, a complementary companion designated as &ldquo
Pension Schemes and Falling Birth-Rates: Change in Customs or Microeconomic Optimization?
2004
In this paper, we develop an overlapping generations model where fertility is endogenous. The utility of the parents is a function of the number of their children, and each child implies two types of fixed costs: the financial cost and the cost in terms of time. A "pay-as-you-go" pension scheme introduces an externality in that the number of children will be fewer than optimal because their favorable impact on the level of pension income is not taken into account. First, we define the competitive equilibrium dynamics and the steady state. This allows comparisons with the optimal stationary state, a notion which generalizes the golden rule. Two instruments, pensions and child benefits, are n…
Minimum Leading Edge Protection Application Length to Combat Rain-Induced Erosion of Wind Turbine Blades
2021
Leading edge erosion (LEE) repairs of wind turbine blades (WTBs) involve infield application of leading edge protection (LEP) solutions. The industry is currently aiming to use factory based LEP coatings that can applied to the WTBs before they are shipped out for installation. However, one of the main challenges related to these solutions is the choice of a minimum LEP application length to be applied in the spanwise direction of the WTBs. Generally, coating suppliers apply 10–20 m of LEP onto the blades starting from the tip of the blade using the “rule of thumb”, and no studies in the literature exist that stipulate how these LEP lengths can be calculated. In this study, we extend the sc…
Dynamic Ordering of Firewall Rules Using a Novel Swapping Window-based Paradigm
2016
Designing and implementing efficient firewall strategies in the age of the Internet of Things (IoT) is far from trivial. This is because, as time proceeds, an increasing number of devices will be connected, accessed and controlled on the Internet. Additionally, an ever-increasingly amount of sensitive information will be stored on various networks. A good and effi- cient firewall strategy will attempt to secure this information, and to also manage the large amount of inevitable network traffic that these devices create. The goal of this paper is to propose a framework for designing optimized firewalls for the IoT. This paper deals with two fundamental challenges/problems encountered in such…
