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
A Simulation Analysis of a Reserve Stock Management Policy for Feed Grains and Wheat
During the last three years agriculture has exhibited characteristics that parallel those of a manic depressive. The livestock sector was flying high during 1973 and in the depths of despair in 1974. The crop sector was elevated from two decades of despondent but stable economic health to a state of price elation in 1973 and 1974. Over the last couple of years consumers, who enjoyed excellent food budget health for years, have slipped into a state of belligerent depression. Each group views the future with anxious dismay. Livestock producers fear that the feed prices will remain high, crop producers fear they will not. Neither livestock nor crop producers have a sound basis for making short or longer term production plans.
Fault Diagnosis and CAN Bus/Ethernet Redundancy Design of a Monitoring and Control System
The ship monitoring system is used to monitor and control the working status of various equipment on the ship. The navigational safety of the ship is affected directly by the stable working of the monitoring system. In this paper, a ship monitoring system with fault-type judgment function and bus redundancy is designed to improve system reliability and reduce fault checking cost. A redundant Ethernet/CAN bus communication network is constructed in the system, which connects multiple simulation nodes. The simulation node can simulate the faults that may occur during the communication process and feeds back the fault information to the host computer. The host computer will analyze and display the corresponding fault type on the user interface with the feedback information is received. The system reconfigures the network route autonomously when the simulation node has a communication fault. Routing of fault nodes can be switched to redundant routing, and the load balancing of the communication network can be maintained. Through experimental tests, the system can accurately locate faults and achieve fast switching of redundant routes between buses. Hence, the reliability of data transmission is improved.
