We investigate the use of repeaters to combat the problem of pilot pollution in IS-95 CDMA systems. For the purpose, we have formulated the problem into a manageable optimization model and suggested a greedy-type algorithm that determines the number and locations of repeaters needed. Simulation studies have been carried out by applying the algorithm to an actual CDMA network in which pilot poll...

e observational evidence indicates that recent regional changes in climate, particularly temperature increases, have already a ected a diverse set of physical and biological systems in many parts of the world. Allergens patterns are also changing in response to climate change and air pollution can modify the allergenic potential of pollen grains especially in the presence of speci c weather con...

In a stylized model of international trade, firms in the North indirectly export second-hand products to a representative firm in the South to be reused as intermediate goods, with potential trade gains. The degree of reusability of waste products is a crucial choice variable in the North. This is because with a lack of international vigilance, non-reusable waste can be mixed illegally with the...

According to the pollution haven effect (PHE) mobile capital responds to environmental regulation by moving from countries with high regulation to those with low regulation. Previous tests of the PHE have focused on host country regulation effect. This study also examines the effect of home country regulation on foreign direct investment (FDI). I use a panel of 28 OECD countries for 1981-2000 t...

Although several studies have explained the effect of urbanization on China’s carbon emissions, most have focused on population urbanization, while ignoring the urban spatial form. This study investigates the impact of urban spatial form, measured by residential density, on the evolution of carbon emissions of 108 cities from 2003 to 2013 in China. The main results are as follows: (1) although ...

Government regulations to address technological risks are important for the successful development and application of nanotechnology, but there is an ongoing debate in the USA about who is responsible for the regulation of nanotechnology. In a mail survey of leading US nano-scientists, we examine scientists’ perceptions about nano-regulation, including the government level (local, national, or ...
