An architecture for calculation of the distance transform based on mathematical morphology

This paper presents a hardware architecture for calculating the city-block and chessboard distance transform on binary images. It is based on applying multiple morphological erosions and adding the result, enabling both processing pixels in raster scan order and a deterministic execution time. Which distance metric to be calculated is determined by the shape of the structuring element, i.e. diamon

Do open-ended survey questions on migration motives create coder variability problems?

Contemporary research on migration has benefi ted from adopting a variety of methodological approaches and different sources of information to provide answers to the ever-recurring question of why people migrate. Yet, when it comes to central methods used for researching migration motives, progress appears to have been slow. This paper focuses on surveys to research migration motives using self-ad

Assertiveness, responsiveness and reciprocity in verbal interaction. Dialogues between children with SLI and peers with typical language development

The present study examined assertiveness and responsiveness in two different conversational contexts: children with specific language impairment (SLI) interacting with an age-matched peer with typical language development (TLD) and children with SLI interacting with a language-matched peer with TLD. The dialogues where the 10 participating children with SLI interacted with an age peer were charact

Adapting to changes in the supply chain – Challenges to re-defining the supply chain for increased customer orientation and product innovation within the paper packaging industry

Supply chains are no longer to be regarded as linear constructs with definite starting and ending points, but as systems, or wholes that are to be customer driven rather than product driven. But however easy it sounds in theory industries are struggling to re-invent or re-comprehend existing business models. This paper aims to describe and identify organizational challenges to re-defining the supp

Coordinated voltage control in medium and low voltage distribution networks with wind power and photovoltaics

Distributed Generation (DG) installations have been increasing during the last years. Wind power and photovoltaics are two of the most common renewable energy sources for DG typically connected to the distribution network (DN) originally planned and built to supply loads. DG units connected to the DN impact the voltage where customers are connected. Network voltage is an important quality criterio

Demographic, Socio-Economic and Environmental Impact of AIDS in Rural Tanzania

The paper forms part of the presentation of the results from a resarch projct looking into socio-economic and environmental aspects of the HIV/ADIS epidemic. The project focuses on Tanzania with a special refernce to Karagwe and Muleba districts in Kagera Region and Makete District in Iringa Region. In this report a more aggregate level is investigated, however. In demographic terms changes in imp
