In this paper, we present various functional means in the sense of convex analysis. In particular, a logarithmic mean involving convex functionals, extending the scalar one, is introduced. In the quadratic case, our functional approach implies immediately that of positive operators. Some examples, illustrating theoretical results and showing the interest of our functional approach, are discussed.

We show how software architectures (including interface descriptions) can be derived from artifacts set up in the analysis phase of the software lifecycle. The analysis phase consists of six steps, where various models are constructed. Especially, the software development problem is decomposed into simple subproblems. The models set up in the analysis phase form the basis for (i) defining softw...

We document music programming in Gibber, a creative coding environment for the browser. We describe affordances for a sample-accurate and functional approach to scheduling, pattern creation and manipulation, audio synthesis, using rhythm and harmony, and score definition and playback.

The functional approach of the Technological Innovation System (TIS) has become important in innovation theory to understand the dynamics of technological innovations. Until now, TIS has mainly been applied topdown from a policy perspective. The aim of this study was to investigate whether TIS can be used in the management domain, from an actororiented perspective, to explain the dynamics in wh...

Imagine you have traveled to an unfamiliar city. Before you start your daily tour around the city, you need to know a good route. In Network Theory (NT), this is the traveling salesman problem (TSP). A dynamic programming algorithm is often used for solving this problem. However, when the road network of the city is very complicated and dense, which is usually the case, it will take too long fo...

Evaluation measures, objective and subjective, are used to assist users in finding interesting association rules. Objective measures are more general, but they can be insufficient because they do not consider user’s and domain features. However, getting user’s knowledge and interest needed to calculate subjective measures can be a difficult task. Thus, this work presents a methodology to identi...

Three major puzzles, described later in this section, have captured the attention of macroeconomic finance: the equity-premium, riskfreerate and equity-volatility puzzles. A common strand of these three asset-return puzzles is that markets are behaving as if investors fear some unknown hidden randomness that isn’t obvious from the data. People are acting in the aggregate like there is much more...

Conventional compilers often are large entities that are highly complex, di cult to maintain and hard to reuse. In this article it is argued that this is due to the inherently functional approach to compiler construction. An alternative approach to compiler construction is proposed, based on object-oriented principles, which solves (or at least lessens) the problems of compiler construction. Th...

Introduction The material interpretation of conditionals is commonly recognized as involving some paradoxical results. I here argue that the truth functional approach to natural language is the reason for the inadequacy of this material interpretation, since the truth or falsity of some pair of statements ‘p’ and ‘q’ cannot per se be decisive for the truth or falsity of a conditional relation ‘...

This article presents a qualitative analysis showing the dependency of effective collaborative argumentation on interpersonal relational aspects that develop during synchronous interaction. Four regulatory principles are proposed as propelling the interaction, and of these, autoregulation, or the conservative restraints within the existing relation, appears to be the dominant force. When using ...
