In this paper a complete strategy for scene modelling from sensory data acquired in a natural environment is defined. This strategy is applied to outdoor mobile robotics and goes from environment recognition to landmark extraction. In this work, environment is understood as a specific kind of landscape, for instance prairie, forest, desert, etc. A landmark is defined as a remarkable object in t...

Component testing indicates that overheating in tropical buildings could be reduced using walls built from upcycled sand-filled plastic bottles, which also reduces building costs and prevents waste polluting the environment. It is not yet known, however, how these bottle-composite influence thermal comfort dwellings in-situ. This study presents world's first in-situ measurement of indoor temper...

BACKGROUND Quantitative measurements of mould enrichment of indoor air or house dust might be suitable surrogates to evaluate present but hidden moisture damage. Our intent was to develop a house-dust monitoring method to detect hidden moisture damage excluding the influence of outdoor air, accumulated old dust, and dust swirled up from room surfaces. METHODS Based on standardized measurement...

This paper contains measured data and empirical models for 5.85 GHz radio propagation path loss in and around residential areas. Three homes and two stands of trees were studied for outdoor path loss, tree loss, and house penetration loss in a narrowband measurement campaign that included 270 local area path loss measurements and over 276,000 instantaneous power measurements. The data will aid ...

The restorative potential of green outdoor environments for children in preschool settings was investigated by measuring the attention of children playing in settings with different environmental features. Eleven preschools with outdoor environments typical for the Stockholm area were assessed using the outdoor play environment categories (OPEC) and the fraction of visible sky from play structu...

Objective Allergic rhinitis (AR) is a major chronic respiratory disease due to its prevalence, impact on quality of life (QL), economic burden, link with asthma. During the last years, many countries have experienced an increase in the prevalence of respiratory allergy. A significant contribution in development of AR, in addition to house dust mite, cockroaches, dogs, cats, pollen and trees, se...

one of the major aspects of quality of life is place-attachment which is affected by human-nature interactions. looking at such a critical issue in human settlements requires the study of the relationship between architecture and nature. it is a critical issue in the contemporary literature of built environment and is discussed in specific frameworks such as phenomenology and environmental psyc...
