A growing number of collaborative networked organizations can be found in industry, services, and research. However, the lack of a reference model that could synthesize and formalize the base concepts, principles, and recommended practices, is an obstacle for an easier and more consistent development of the area. Therefore a reference modeling approach is proposed considering multiple modeling ...
Communicative action concerns achieving and maintaining mutual understanding among all those who are involved in a coordinated (organizational) situation. Communicative action is embedded in a social context. Current approaches in the Language/Action Perspective have focused mainly on the dynamic aspect of language, that is, on (business) conversation. In this paper, we develop a new model of c...
We propose a real-time and accurate solution to the Perspective-n-Point (PnP) problem –estimating the pose of a calibrated camera from n 3D-to-2D point correspondences– that exploits the fact that in practice the 2D position of not all 2D features is estimated with the same accuracy. Assuming a model of such feature uncertainties is known in advance, we reformulate the PnP problem as a maximum ...
This study is about outlier detection in time series data. The main objective is to derive and to test statistics for detecting additive outlier (AO) and innovative outlier (IO) in GARCH(1,1) processes and subsequently to develop a procedure for testing the presence of outliers using the statistics. A test statistic has been derived for each type of outlier. In the derivation of the statistics,...
The issue of the paper is how to characterize public e-services mediated through the web. One common kind of characterization is made through stage models (e-ladders). Such models are frequently used for policy-planning, evaluation and bench-marking of public e-services. E-ladder models have been criticized and as an alternative the e-diamond model has been formulated, which consists of twelve ...
This paper examines some standard open-economy New Keynesian models to address the question of how globalisation affects the inflation process. Specifically, it investigates how the Phillips curve for consumer price inflation in a country is affected by openness, and how the optimal choice of monetary policy is influenced by openness. The paper compares models that assume producer currency pric...
The game of football demands new computational approaches to measure individual and collective performance. Understanding the phenomena involved in the game may foster the identification of strengths and weaknesses, not only of each player, but also of the whole team. The development of assertive quantitative methodologies constitutes a key element in sports training. In football, the predictab...
In this paper, we propose a refinement of Chevallard’s algebraic modeling while still fully agreeing with his position that it is a key process in knowing mathematics. In doing so, based on our empirical study, we claim that: 1) there are two other stages in the algebraic modeling process; 2) it is nonlinear; and 3) partial models are constructed as well. Research on Chevallard's modeling persp...
We present a novel and fast algorithm to solve the Perspective-n-Point problem. The PnP problem estimating the pose of a calibrated camera based on measurements and known 3D scene, is recasted as a minimization problem of the Object Space Cost. Instead of limiting the algorithm to perspective cameras, we use a formulation for general camera models. The minimization problem, together with a quat...
In this paper the architecture and implementation of Cooperative Information Agents (CIA) is described. Taking a language-action perspective to the design of CIAs allows for the specification of obligations and authorizations, and results in the separation of tasks (things the agentmust do) and contracts (mutually agreed commitments to the course of communication). The architecture describes th...
