Contemporary entrepreneurial research has experienced the shift from examining various characteristics of (nascent) entrepreneurs to investigating career pathways that lead to entrepreneurship. The proposed paper develops the analytical framework which complements this career perspective on entrepreneurship with the economic geography perspective on spatial mobility as a knowledge accumulation mec
How does a mobile game become a sport related community with its own cultural expressions and norms? This explorative article examines Turf, a mobile game where the players use the GPS function to navigate both a digital map and the physical landscape. By locating digital zones in the landscape, similar to the sport ori- enteering, the player gains points. Around the game various social activities
A graphics-based information system for process control applications is presented. All pieces of information, such as plant documentation, controller structures, control algorithms and run-time data, are positioned on virtual screens. The user selects the information to be presented on his monitor by “moving” in front of these screens using joysticks. Hierarchically structured information is handl
This article examines the interpretation of biosignatures, the signs of life that could bedetected in outer space. In astrobiology biosignatures could be of various kinds, fossils, molecules, traces, artefacts, structures, electromagnetic waves, etc. The purpose of this article is to bring some semiotic order in this seemingly chaotic variation of signs. It turns out that the semiotic function of
Thermoresponsive microgels find widespread use as colloidal model systems, because their temperature-dependent size allows facile tuning of their volume fraction in situ. However, an interaction potential unifying their behavior across the entire phase diagram is sorely lacking. Here we investigate microgel suspensions in the fluid regime at different volume fractions and temperatures, and in the
A three-language book Swedish, English and Arabic, that includes the information about the project entitled: Photograph and Film for freedom and Democracy, that funded by Swedish Institute, and Organized by Ibn Rushd Association and pertnership with Yemeni Idintity Organization and Lund University, among other partners. Also, it contains the thirty photos that have been shown in Yemen Art Exhibiti
In TN 18.057 a nonlinear system with a white noise forcing function was analyzed. In this note we will study a first order linear system 'which has a white noise forcing function and white noise paramneter fluctuations. The results are derived from the Fokker-Planck equation. It is found that the boundaries are always natural which means that no boundary conditions can be applied.
The parabolic equation is approximated by a set of ordinary differential equations and by finite difference equations. special attention is given to the approximation of the boundary condition. Some identities suitable to check numerical calculations are also derived.
Results of simulation of the scheme for cross machine stretch estimation and prediction are given. In the simulation we use data with known statistical properties.
