Smart spaces research focuses on technology for multiple displays and devices for collocated participants. In most approaches, however, users have to cope with heterogeneous interfaces and information organization, as well as a lack of support for collaboration with mobile and remote users outside the smart space. In this paper, we present ReticularSpaces;(More)
Distributed interaction is a computing paradigm in which the interaction with a computer system is distributed over multiple devices, users and locations. Designing and developing distributed interaction systems is intrinsically difficult as it requires the engineering of a stable infrastructure to support the actual system and user interface. As an(More)
Constraint Satisfaction Problems (CSP) and Integer Linear Programming Problems (ILP) in their decision form are both N P-complete problems and thus rely on tree-search techniques for their solution. Despite several similarities in the solution algorithms, the two research fields have developed in quite separate directions. Recent attempts however indicate(More)
Orienteering is a sport in which the orienteer completes a course of control points in the shortest possible time, aided only by map and compass. As in all forms of sport, it is necessary to ensure that the conditions of competition are the same for all competitors. The more accurate the map, the better this can be done, and the greater the opportunity for(More)
The proximate composition of seeds and main physicochemical properties and thermal stability of oil extracted from Lannea microcarpa seeds were evaluated. The percentage composition of the seeds was: ash (3.11%), crude oil (64.90%), protein (21.14%), total carbohydrate (10.85%) and moisture (3.24%). Physicochemical properties of the oil were: refractive(More)
Interactive workspaces are increasingly physically distributed, highlighting the challenge of building interfaces that support group interaction with digital documents through multiple locations and devices. This paper presents the technical implementation and user interface of <i>ReticularSpaces</i>. Based on the concepts and principles of Activity-Based(More)
—Turbulence of the incoming wind field is of paramount importance to the dynamic response of civil engineering structures. Hence reliable stochastic models of the turbulence should be available from which time series can be generated for dynamic response and structural safety analysis. In the paper an empirical cross spectral density function for the(More)
Two different partially recurrent neural networks st,ruc-tured as Multi Layer Perceptrons (MLP) are inves tigated for time domain identification of a nonlinear structure. The one partially recurrent neural network has feedback of a displacement component from t,he output layer to a tapped-delay-line (TDL) input layer. The other recurrent neural network bazd(More)
