There are many problems in conceptual modeling process, such as sharing difficulty in modeling conception, complexity of modeling method, difficulty in cooperative modeling by experts from different domains, and so on. To solve those problems, by establishing expression rules of metadata and semantics of geographical models, introductive geographical modeling approaches is put forward here to r...

Knowledge of the distance between a robot and its surrounding environment is vital for any robotic system. The robot must obtain this information rapidly in order to plan and react in realtime. Our technique rst surrounds the robot links and the obstacles by optimal ellipsoids, and then computes the clearance of the links from the obstacles with a generalized distance function. This approach o ...

This paper studies the role of geographic proximity for interaction on R&D, by exploring the special case of university-industry contacts. While numerous studies find that geographic proximity facilitates spillover effects between university and industry by utilising evidence from e.g. patenting and publishing activities, the geographical dimension is largely understudied in studies that report...

Toponym disambiguation or location names resolution is a critical task in unstructured text, articles or documents. Our research explores how to link ambiguous locations mentioned in documents, news and articles with latitude/longitude coordinates. We designed an evaluation system for toponym disambiguation based on annotated GEOCLEF data. We implemented a node-based approach taking population ...

In this contribution the authors examine robotics research itself. We look at the data which the European funded ECHORD project (European Clearing House for Open Robotics Development) generated. The project began in January 2009 with the ambitious goal of bringing together European robotics manufacturers with the European research institutions and it ended in 2013. We will especially look at th...

Network wide broadcasting is an energy intensive function. In this paper we propose a new method that performs transmission power adaptations based on information available locally, to reduce the overall energy consumed per broadcast. In most of the prior work on energy efficient broadcasting it is assumed that the originator of the broadcast has global network information (both topology inform...

The oldest branch of dialectology is the study of what is today often referred to as " dialect geography " , i.e. the study of the geographical distribution of language varieties, as opposed to the study of many other relations between language varieties and external conditioning factors, such as social class, age, and sex. While it is clear that geography has a massive influence on the distrib...

Research has increasingly focused on intentional or planned lesbian, gay, bisexual (LGB)parent families; however, how young adults in these families navigate the aftermath of parental break-up and subsequent repartnering is unexamined. This qualitative study of 20 young adults who had experienced their LGB parents’ relationship dissolution and/or the formation of an LGB stepfamily examined how ...

While the debate on whether countries should or should not sign trade agreements with selected partners continues, governments have significantly stepped up the rate at which they enter into such agreements. A number of such agreements have been signed lately and many more are under negotiation. Multinational firms get impacted by these agreements irrespective of whether these are beneficial to...

Context: The context of this paper is Global Software Development (GSD) which is a current trend concerning the development of software in a distributed manner throughout different countries. This paradigm has several advantages, but unfortunately there are a number of challenges that hinder projects’ successful development. Objective: The main goal of this paper is to discover which factors af...
