As a part of the day-ahead market clearing process, Midcontinent Independent System Operator (MISO) solves one of the largest and most challenging Security Constrained Unit Commitment (SCUC) models. Better computational performance of SCUC models not only improves the market efficiency but also facilitates future market development. This paper introduces two developments on Mixed Integer Progra...

This paper discusses the velocities of escaped savings and financial liquidity, as well minimum mixed savings. means that examined behavior money cycle under normal conditions, due to velocity at their lower level liquidity. As a result, determines how economy operates in this case. Thence, it is plausible extract conclusions about consumption investments each economy. For analysis Q.E. method ...

Nutrient pollution is one of the major sources of water quality impairments in the U.S. Agriculture is a major source of nutrients. Two alternative strategies for reducing nutrient loads from cropland are to reduce fertilizer application rates and to filter nutrients coming off cropland with restored wetlands. These two approaches are evaluated in the Mississippi Basin, where nutrient loadings ...

Atmospheric levels of carbon dioxide are tightly linked to the depth at which sinking particulate organic carbon (POC) is remineralised in the ocean. Rapid attenuation of downward POC flux typically occurs in the upper mesopelagic (top few hundred metres of the water column), with much slower loss rates deeper in the ocean. Currently, we lack understanding of the processes that drive POC attenu...

Female Labor Market Transitions in Europe Using micro panel data, labor market transitions are analyzed for the EU-member states by cumulative year-by-year transition probabilities. As female (non-)employment patterns changed more dramatically than male employment in past decades, the analyses mainly refer to female labor supply. In search for important determinants of these transitions, six EU...

The biological activities of tocotrienols are receiving increasing attention. Herein, we report the efficacy of a mixed-tocotrienol diet against prostate tumorigenesis in the transgenic adenocarcinoma mouse prostate (TRAMP) mouse model. Male TRAMP mice, 8 wk old, were fed 0.1%, 0.3%, or 1% mixed tocotrienols in AIN-76A diet up to 24 wk old. Likewise, a positive control group consisting of male ...

In this paper we consider multigrid algorithms for nonconforming and mixed nite element methods for second order elliptic problems on triangular and rectangular nite elements. We prove optimal convergence properties of the W-cycle multigrid algorithm and uniform condition number estimates for the variable V-cycle preconditioner. Lower order terms are treated, so our results also apply to parabo...
