Why do gasoline prices react to things that have not happened
Some people complain they are being gouged at the pump, but raising prices now in anticipation of what might happen helps ensure an adequate gas supply.
Consumer Gasoline Prices in 2014: What Caused the Decline?
Though a large body of literature analyzes commodity markets in general as well as the crude oil market, little work looks at the determinants of gasoline price shocks and which variables contributed to specific historical shocks. Using a structural vector autoregression (SVAR) model, one can determine how gasoline prices typically respond to shocks in price determinants, how much each variable, on average, contributes to the variation in gasoline, and which variables influenced gasoline prices during particular shocks. This paper proposes a simple SVAR model of the gasoline market and uses the model to determine what caused gasoline prices to decline between June 2014 and February 2015.
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.
