Collaborative networked organizations are complex entities whose proper understanding, design, implementation, and management require the integration of different modeling perspectives. A comprehensive modeling framework is therefore proposed as a first step towards the elaboration of a reference model for collaborative networks. Modeling tools and theories developed in other disciplines are al...

This paper reports an observation of communication in collaborative design by examining several historical cases of building design projects. It will present three cases of teamwork in architectural modelling. Each case provides a collection of drawings or illustrations that depict the artefacts being designed and constructed. Looking at the cases from the design as modelling perspective, two i...

In this paper, we examine the demand for fresh water of China in 2025 from the complex system modeling perspective and we develop an efficient, economical and practical water strategy to meet the demand for fresh water in 2025.Different from previous research, this study focus on studying several factors that can influence the demand for fresh water, and their interplay within the complex large...

The "perspective-plane" problem proposed in this paper is similar to the "perspective-n-point (PnP)" or "perspective-n-line (PnL)" problems, yet with broader applications and potentials, since planar scenes are more widely available than control points or lines in practice. We address this problem in the Bayesian framework and propose the "Bayesian perspective-plane (BPP)" algorithm, which can ...

A group-theoretic analysis is applied to nd the transformation of the homogeneous control points of k-dimensional B ezier simplices (such as two dimensional triangles and three dimensional tetrahedra) under a k-dimensional projective reparameterization. This transformation has applications in the perspective projection of textures represented as triangular spline intensity surfaces , in arbitra...

The present study aimed to understand the care provided to patients with HIV/AIDS in Portugal according to the healthcare providers' perspective. Thompson's method of oral history was used in the study, which included 22 healthcare providers. The data were collected by means of semi-structured interviews and were analyzed from the narrative compilation perspective formulated by the author using...

In this paper, we study the widely used nearest shrunken centroid classifier (NSC, also known as PAM) for microarray data from the supervised dimension reduction perspective. A simple modification is proposed and through application to public microarray data, we illustrate the favorable performance of the proposed method. Supplementary information can be found at http://www.biostat.umn. edu/~ba...

We study generalized Horn-Kapranov rational parametrizations of inhomogeneous sparse discriminants from both a theoretical and an algorithmic perspective. We show that all these discriminantal parametrizations are birational, we prove some results on the corresponding implicit equations, and we propose a combinatorial algorithm to compute their degree in the uniform case of (co)dimension 3.

In this paper, we consider the Grand Challenge under a very specific perspective: the enabling of application experts without programming knowledge to reliably model their business processes/applications in a fashion that allows for a subsequent automatic realization on a given platform. This goal, which aims at simplifying the tasks of the many at the cost of ambitious and laborious tasks for ...
