Particle swarm optimization (PSO) has received increasing attention in solving multi-objective economic dispatch (ED) problems in power systems because of parallel computation, faster convergence, and easier implementation. This paper presents a detailed overview of multi-objective particle swarm optimization (MOPSO) and provides a comprehensive survey on its applications in power system econom...

Contemporary societies are experiencing growing diversity both at different levels (firms, cities, regions, countries) and in different arenas (cultural, social, and economic). One of the main reasons is the process of globalization that has pushed the cross-country flows of ideas, knowledge, goods, capital and people. Undoubtedly, no feature of globalization is considered with more unease than...

PURPOSE To evaluate the efficacy and cost savings of outpatient management of post-fine-needle aspiration (FNA) pneumothoraces with small-caliber catheters. MATERIALS AND METHODS The authors retrospectively reviewed the medical and hospital billing records from 74 patients with enlarging or symptomatic post-FNA pneumothoraces treated with a small-caliber catheter. Forty patients (54%) were tr...

Controlling the consumption profile of office buildings can be used to provide balancing services to the power grid at a financial benefit without violating its thermal comfort constraints. The economic advantage of such a service is a reduction in the total operating cost, but also an increase in average occupants’ comfort when using our control scheme. We study these effects for the case of p...

The Federal Australian Government has used the results of computer modelling by ABARE, which predict supposedly major economic costs from reducing greenhouse gas emissions, to justify its international stance arguing for the right for Australia to continue increasing emissions. Attempts to challenge this modelling have been hampered by the lack of detail given over the assumptions within the mo...

We estimate a structural model of schooling, labor supply and life-cycle earnings in which some individuals have comparative advantage in producing skills in school while others are better at producing skills in the labor market and analyze some of its key implications. The model is estimated using a sample of white males taken from the 1979 cohort of the National Longitudinal Survey of Youth (...
