Optimal flock structure of pig farm providing minimum costs

COMPARISON BETWEEN MINIMUM AND NEAR MINIMUM TIME OPTIMAL CONTROL OF A FLEXIBLE SLEWING SPACECRAFT

In this paper, a minimum and near-minimum time optimal control laws are developed and compared for a rigid space platform with flexible links during an orientating maneuver with large angle of rotation. The control commands are considered as typical bang-bang with multiple symmetrical switches, the time optimal control solution for the rigid-body mode is obtained as a bang-bang function and app...

Löffler syndrome on a Louisiana pig farm

Löffler syndrome, a fulminant eosinophilic pneumonitis associated with the larval migratory phase of human parasites, is rarely reported in the United States. A previously healthy 8-year-old male was hospitalized with tachypnea, cough, hypoxemia, and fever of one week's duration. History revealed exposure to pigs on his family's farm in southernmost Louisiana, where the patient was responsible ...

Managerial Flexibility, Agency Costs and Optimal Capital Structure

This paper investigates the effect of managerial flexibility on the choice of capital structure for a firm and the corresponding valuation of its long term debt. We consider a general model in continuous time where the manager (who is not a shareholder) of a firm with long term debt in place may dynamically switch strategies at random times so as to maximize his expected discounted compensation...

Optimal slaughter pig marketing

The problem of optimal marketing of slaughter pigs has been examined by a wide range of authors (e.g. Rasmussen, 1973; Wendt, 1979; Jolly et al., 1980; Chavas et al., 1985; Sundermeier et al., 1987; Giesen et al., 1988; Broekmans, 1992; Jørgensen, 1993; Boland et al., 1993; de Lange & Schreurs, 1995 (based on the model of Black et al., 1986)). Many different approaches have been taken, but in g...
