Cost Reduction of Telecommunication Network Provisioning Operation and Maintenance is today a strategic issue for Telco operators. Workforce Management (WFM) environments and techniques allow a dramatic cost and performance improvement for the "on the field" technicians management. Basic functionalities offered by the WFM environments are: automated task assignment to workers and mobile office ...

Current approaches to the formal representation of geographical reality are characterized by their static character. GIS representations are representations of the world at a given time, reflecting the fact that geographic information systems have their roots in printed maps. Yet, geographical reality, like all other domains of reality, is essentially dynamic. We here outline a theory that is d...

Mobile e-commerce (m-commerce) is defined as all activities related to a commercial transaction conducted through communications networks that interface with wireless (or mobile) devices. It is started recently to appear in the scene by exploiting the advantages of internet, mobile computing and mobile communications in order to provide a large number of advanced services to mobile users. In th...

This paper begins to explore the determinants of the topological properties of the international-trade network (ITN). We fit bilateral-trade flows using a standard gravity equation to build a " residual " ITN where trade-link weights are depurated from geographical distance, size, border effects, trade agreements, and so on. We then compare the topological properties of the original and residua...

Whatever the data source, or the capture process, the creation of a building footprint in a geographical dataset is error prone. Building footprints are designed with square angles, but once in a geographical dataset, the angles may not be exactly square. The almost-square angles blur the legibility of the footprints when displayed on maps, but might also be propagated in further applications b...

BACKGROUND/AIMS Molecular epidemiology of hepatitis C virus (HCV) shows that HCV genotypes are unique with respect to their nucleotide sequence, geographical distribution and clinical relationship. METHODS In this study we enrolled 67 HCV-infected individuals with various stages of liver disease from four geographical regions of Turkey. A partial NS5B region of the HCV genome was sequenced an...

Geographers have been reticent on the role of the African diaspora in the contouring of Brazil’s biological and cultural landscapes. Whereas paradigm shifts have occurred in regards to environmental stability in the tropical realm and the pristine nature of pre-Columbian landscapes, these have not translated to a rigorous reassessment of the geographical position of Africans and their descendan...

Information agents on mobile computing environment should adaptively provide information based on the changing location of mobile users. The agent has to obtain user’s location dynamically, and respond him the information or service depending upon his geographical position. We propose a novel framework for location-aware information agent that operates on the Wireless Application Protocol (WAP)...

Real-time labeling of geographical landmarks is a simple wearable computing application. Most current systems are based on calculation of optical flow between the current and previous frames to adjust the label position. Here we present two alternative algorithms based on geometrical image constraints .The first is based on epipolar geometry and provides a general description of the constraints...
