Experiences with Recent Price Stabilization Programs for Agriculture
The stabilization of farm prices and incomes has been a goal of all farm legislation dating back to the establishment of the Farm Board in 1929. After the Farm Board concept failed in the wake of the great crash of 1929, price stabilization turned more and more toward price supports with prices set above market equilibrium. To absorb the differential quantities that arose, loan and storage programs were established for major commodities. Stocks of accumulated grain were used in times of war or world grain production shortfalls to even out the flow of food to consumers
Administered Pricing by Cooperatives: Effect on Producer and Consumer Prices and Sales of Fluid Milk
Considerable controversy exists with regard to pricing agricultural commodities, especially when pricing departs from classical market concepts dependent on equating supply and demand. In a recent study of alternative Class I pricing systems, it was suggested that “pricing of milk and dairy products is one of the major policy issues to be resolved in the 1970s”. A different pricing system in federal milk orders was considered urgent enough that a concentrated study of pricing alternatives was pursued by the U.S. Department of Agriculture.
Research on Control and Planning of Soft-Wing UAV for Haze Removal
The existence of fog and haze has caused great pollution to the environment. The research of removing haze is a hot topic in recent years. In this paper, a special haze removal algorithm based on Soft- Wing UAVis proposed. In this algorithm, two track control strategies are designed based on the Soft-Wing UAV model transfer function. A SIMULINK platform based mathematical model of Soft-Wing UAV is built to testified effectiveness of the two track control strategies. An autonomous ergodic-planning algorithm with greedy strategy and foldback algorithm for Soft-Wing UAV is designed. Within the algorithm, the haze regional has been modelled, the cost matrix is constructed, and the planning and ergodic strategy is proposed. Finally, the experimental results validates the reliability of the algorithm in the application of haze removal with the proposed evaluation Index.
