Smart Dust particles, are small smart materials used for generating weather maps. We investigate question of the optimal number of Smart Dust particles necessary for generating precise, computationally feasible and cost effective 3–D weather maps. We also give an optimal matching algorithm for the generalized scenario, when there are N Smart Dust particles and M ground receivers.

For most sub-Saharan African (SSA) cities, in order to control the historically unplanned urban growth and stimulate sustainable future urban development, there is a need for accurate identification of the past and present urban land use (ULU). However, studies addressing ULU classification in SSA cities are lacking. In this study, we developed an integrated approach of remote sensing and Geogr...

This paper describes a study of the role and methods for context capturing in smart spaces. The collected context information is captured for further use by pro-active services provided in user-centric service spaces. Another aspect addressed by the paper is representation of the Network Protocols and Algorithms ISSN 1943-3581 2012, Vol. 4, No. 4 www.macrothink.org/npa 85 collected context data...

INTRODUCTION A long and protracted civil war compounded by the occurrence of nature-related disasters have forced thousands of Somalis to take refuge in camps for internally displaced persons (IDPs) to escape violence and seek shelter. Dwellers of these camps have limited accessibility to and affordability of the fractured healthcare facilities located in nearby towns. A free, outreach, mobile,...

BACKGROUND In Argentina, dengue has affected mainly the Northern provinces, including Salta. The objective of this study was to analyze the spatial patterns of high Aedes aegypti oviposition activity in San Ramón de la Nueva Orán, northwestern Argentina. The location of clusters as hot spot areas should help control programs to identify priority areas and allocate their resources more effective...

The study area of Marand city is 45 ° 46 'east longitude and 38 ° 26' north latitude and is located in the northwest of East Azarbaijan province and 60 km northwest of Tabriz province. Unfortunately, in recent years, the development of countries, including Iran, has led to more exploitation and improper use of groundwater resources, which reduces these resources and does not control the amount ...

Continuous monitoring of drinking water quality is essential in terms of heavy metals and toxic substances. The general objective of this study were to determine the concentration of heavy metals in drinking water of Khorramabad city and to determine the water quality indices (The heavy metal pollution index and heavy metal evaluation index). According to the city map, 45 points were selected f...

This paper describes how the NGO Shelter Associates and an organization of women and men slum dwellers worked together to collect information on each household in slum settlements in Pune and Sangli and to map this, along with infrastructure and service provision and each slum’s position within the city. This permitted data on slums to be superimposed on these cities’ development plans using a ...

3D city models are important in urban planning for sustainable development. Urban planners draw maps for efficient land use and a compact city. 3D city models based on these maps are quite effective in understanding what, if this alternative plan is realized, the image of a sustainable city will be. However, enormous time and labour has to be consumed to create these 3D models, using 3D modelli...

In this work we present an application of InSAR and gravimetric surveys for risk management related to land subsidence and surface ground faulting generation. A subsidence velocity map derived from the 2007–2011 ALOS SAR imagery and a sediment thicknesses map obtained from the inversion of gravimetric data were integrated with a surface fault map to produce a subsidence hazard zoning in the cit...
