The expected high penetration of battery chargers for electric vehicles (EV) in electric networks is foreseen as a potential problem for power quality. Battery chargers are nonlinear devices that inject harmonic currents and pollute network voltages. Thus, their harmonic emissions must be analyzed and reduced by harmonic mitigation techniques to avoid future problems. This paper analyzes and re...

There has been an upsurge of interest in moral decision making, which appears to have some distinctive properties. For example, some moral decisions are so strongly influenced by ideas about how sacred entities are to be treated, that they seem to be relatively insensitive to the costs and benefits entailed (e.g., ‘‘do not allow companies to pollute the earth for a fee, even if pollution credit...

We study decisions in a dynamic game where firms’ private production leads to accumulation of a public bad, for example in the form of pollution. Firms have an option to invest in clean technology, which lowers emissions, or contributions to the public bad. The main treatment variable is access to clean technology, or benefits from such investment, which can be private or common. In the private...

Word level translational equivalences can be extracted from parallel texts by surprisingly simple statistical techniques However these techniques are easily fooled by indirect associations pairs of unrelated words whose statistical properties resemble those of mutual translations Indirect associations pollute the resulting translation lexicons drastically reducing their precision This paper pre...

mass generation of bagasse wastes from every 100 kg of sago starch pith being processed are likely to pollute the water when they are discarded into rivers. the increase of livestock production increases manure production and improper management of these manures will pollute the soil and environment, and causing diseases outbreak. co-composting of sago bagasse and chicken manure could serve as ...
