Needs for increased product quality, reduced pollution, and reduced energy and material consumption are driving enhanced process integration. This increases the number of manipulated and measured variables required by the control system to achieve its objectives. This paper addresses the question of whether processes tend to become increasingly more difficult to identify and control as the proc...

When we use a mathematical model to represent information, we can obtain a closed and convex set of probability distributions, also called a credal set. This type of representation involves two types of uncertainty called conflict (or randomness) and non-specificity, respectively. The imprecise Dirichlet model (IDM) allows us to carry out inference about the probability distribution of a catego...

Enthymeme reconstruction, i.e. the task of reformulating arguments with missing propositions, is an exciting task at the borderline of text understanding and argument interpretation. However, there is some doubt in the community about the feasibility of this task due to the wide range of possible reformulations that are open to humans. We therefore believe that research on how to define an obje...

Rootkits pose a dilemma in forensic investigations because hackers use them surreptitiously to mislead investigators. This paper analyzes the effectiveness of online and offline information analysis techniques in detecting rootkits and determining the processes and/or files hidden by rootkits. Five common rootkits were investigated using a live analysis tool, five rootkit detection tools (RDTs)...

The purpose of this paper is to present a new approach to econometric modeling of substitution and technical change. Substitution is determined by observable variables, such as prices of output and inputs and shares of inputs in the value of output. Our principal innovation is to represent the rate and biases of technical change by unobservable or latent variables. This representation is consid...

Der Themenbeitrag reflektiert die Zielund Problemstellungen eines Wissensmanagements in der praktischen Arbeit, insbesondere in verteilten Projekten und bei Offshore-Outsourcing, und zeigt entsprechende Lösungsansätze auf. Er geht außerdem auf Realisierungsmöglichkeiten/-beispiele für ein systemgestütztes Wissensmanagement in verteilten Entwicklungsund Wartungsprojekten ein und berichtet über E...

In many applications, including climate science, power systems, and remote sensing, multiple input variables are observed for each output variable and the output variables are dependent. Several methods have been proposed to improve prediction by learning the conditional distribution of the output variables. However, when the relationship between the raw features and the outputs is nonlinear, t...

This paper compares two approaches to definition of the environmental and organizational influence constructs in strategic management research by quantitatively examining loading of variables on these constructs versus the predominant qualitative approach to construct definition in the field. Variables operationalizing competition, network externalities, and community resources were used to cap...

Many past studies documented a strong evidence of a linkage between stock prices and macroeconomic activities across different stock markets and time horizons. However, most of these studies have focused on developed economies and highlighted the impact of either domestic variables or a few global factors. In recent times, the impact of global macroeconomic factors upon stock returns has garner...

This paper empirically explores the determinants of corporate research and development (R&D) intensity in the Canadian context with a sample of 134 TSE companies. Specifically we investigate in cross-section the impact of various governance and firm-specific variables on firms’ R&D intensity. We find that, in the case of governance variables, percentage of inside director, Directors’ ownership,...
