It is trivial to observe differences between cultures: people use different languages, have different modes of building houses and organize their cities differently, to mention only a few. Differences in the culture of different people were and still are one of the main reasons for travel to foreign countries. The question whether cultural differences are relevant for the construction of Geogra...

We consider (un)decidability of Multi-Lane Spatial Logic (MLSL), a multi-dimensional modal logic introduced for reasoning about traffic manoeuvres. MLSL with length measurement has been shown to be undecidable. However, the proof relies on exact values. This raises the question whether the logic remains undecidable when we consider robust satisfiability, i.e. when values are known only approxim...

This paper describes large scale implementations of spatial audio systems which focus on the presentation of simplified spatial cues that appeal to auditory spatial perception. It reports a series of successful implementations of nested and multiple spatial audio fields to provide listeners with opportunities to explore complex sound fields, to receives cues pertaining to source behaviors withi...

The paper analyzes spatial Cournot competition among multi-store firms. It demonstrates that the complex problem of determining equilibrium store locations for competing multi-store firms can be approximated by a simple one, in which each firm behaves as a multi-store monopolist in choosing its store locations. A firm’s equilibrium store locations often coincide with its monopoly locations, and...

Numerical simulations resultant from the Ice Sheet Model Intercomparison Project (ISMIP6), the Sea-Ice Model Intercomparison Project (SIMIP) and other components of the Coupled Model Intercomparison Project 6 (CMIP6) will produce many different spatial variables, from a number of models, a number of experiments and for several scenarios. The typical approaches for analysis of multi-variate mult...

Existing product derivation approaches focus on support for single users resolving variability based on a single variability model. However, in practice multiple users perform product derivation of large-scale systems with system-ofsystems architectures in a distributed and asynchronous manner. It is infeasible to describe the variability of such multi product lines with one integrated model. R...

A neuronal model made of two interconnected parts-a den-drite and a trigger zone-is considered under the action of white noise and periodic inputs acting on the dendritic compartment. It is shown analytically how the variability of the depolarization potential is decreased from the dendritic to the trigger zone for subthreshold behavior. These ltering properties of the model are also shown when...

Spatial data are complex and have spatial components and uncertain properties. It is important to develop effective spatial and aspatial indexing techniques to facilitate spatial and/or aspatial querying for databases that deal with spatial &a. In this study we discuss a number of spatial index structures, such as Multi-level grid file (ML,GF), R-tree, and R*-tree, for spatial andor aspatial qu...

A common approach to the conservation of farmland biodiversity and the promotion of multifunctional landscapes, particularly in landscapes containing only small remnants of non-crop habitats, has been to maintain landscape heterogeneity and reduce land-use intensity. In contrast, it has recently been shown that devoting specific areas of non-crop habitats to conservation, segregated from high-y...

One of the main challenges in variability management is the visualization and management of industry size variability models. In this work, we introduce our CASE tool MUSA that uses a multiple perspective approach to variability modeling and is implemented using state-of-the-art multi-touch interfaces. This gives it the power and flexibility to create and manage large-scale variability models. ...
