An experiment is reported which tests whether network information is more effectively displayed in a three dimensional space than in a two dimensional space. The experimental task is to trace a path in a network and the experiment is carried out in 2 0 , in a 3 0 stereo view, in a 3 0 view with head coupled perspective, and in a 3 0 stereo view with head coupled perspective: this last condition...

A trading partner agreement can be used to regulate the cooperation of organizations. It is typically written in natural language which gives rise to misunderstandings when partners interpret it differently. In addition it is often compiled in an unsystematic way so that we might easily overlook a situation the contract should have covered. It is therefore desirable to have a method that can su...

In this paper we present a novel method for automatically and efficiently generating stereoscopic mosaics by registration of optical data collected by a video camera mounted on an airborne platform that mainly undergoes translating motion. The resultant mosaics are seamless and will exhibit correct three-dimensional (3D) views. The basic idea is to fast construct stereo mosaics before 3D recove...

The current state-of-the-art in electronic negotiations shows a focus on the trade of standardised mostly inexpensive products in fixed networks of suppliers and customers. To overcome these shortcomings, the goal must be to enable the trade of complex and valuable goods and to support many-to-many marketplace for that purpose. Once valuable goods are concerned, the trade process involves negot...

Modeling how we choose among alternatives, or more generally, modeling preferences, is one of the core topics of study in Psychology. Preferences can be studied experimentally using a variety of procedures, one of the oldest being the method of paired comparisons. This method remains quite popular in areas such as psychophysics and consumer psychology. For a good overview of the method of paire...

The perspective-N-point problem is a well known issue in computer vision. It consists in the determination of the distance between the camera and a set of points well known in an object coordinate space. This problem has been extensively treated in the literature and is still opened. Many solutions already exist. All these approaches consider only common planar camera. We propose, with a new fo...

This paper presents some key concepts and underlying assumptions of three current fields of research: the Theory of Organized Activity, Organizational Semiotics and Language Action Perspective. All these fields are related by a human/social/organizational common view of Information Systems. In our analysis and, within Organizational Semiotics field Ronald Stamper’s theory was chosen, while with...

The purpose of this study is to propose a scalable architecture that can be supported via the BIM (Building Information Modeling) on a GIS (Geographic Information System) platform for information interoperability between various heterogeneous systems such as BIM, GIS, and FM (Facility Management). This platform requires the acquisition of information from various data sources such as IFC (Indus...

Two sources of document degradation are modeled { i) perspective distortion that occurs while photocopying or scanning thick, bound documents, and ii) degradation due to perturbation in the optical scanning and digitization process: speckle, blurr, jitter, threshold. Perspective distortion is modeled by studying the underlying perspective geometry of the optical system of photocopiers and scann...

Power supply is a bottle-neck problem of wireless micro-sensors, especially where the replacement of batteries is impossible or inconvenient. Now piezoelectric material is being used to harvest vibration energy for self-powered sensors. However, the geometry of a piezoelectric cantilever beam will greatly affect its vibration energy harvesting ability. This paper deduces a remarkably precise an...
