Freezing alarm system based on time series analisys
نویسندگان
چکیده
The aim of this work is to design an alarm system that allows protecting and preventing crop-freezing damages taking decisions with enough time to react. A first step was to obtain a temperature forecast mode. In this line an hourly temperature series was analyzed with Box-Jenkins methodology ( ARIMA models). An alarm system is designed based on these forecast, at each 12 hours, in the air temperatures obtained each hour at real time and in the average errors between real and forecast each hour and each 12 hours. This system generates an index alarm that is related with the risk intensity that over a certain value will activate several sensors. This system is applicable to any area adjusting conveniently the parameters and the ARIMA model.

The present study has made an attempt to discuss the effects of exchange rate volatility and price expectation on maize imports in Iran from 1980 to 2013. In doing so, using the EGARCH technique for time series econometrics, price volatility variables for both exchange rate and final price have been calculated, and the time series for these variables have been extracted. Additionally, in regard...

A framework for fuzzy conceptual clustering of time series is proposed. Static and temporal information is analyzed separately. Temporal reasoning is used to generate temporal rules. The generated rules can be brought into a hierarchy. The framework will be used for the classiication and description of alarm and no-alarm concepts for an intelligent anesthesia monitor. trend analysis by temporal...
متن کاملA Proposal for Fuzzy Rule Generation Using Temporal Reasoning
Knowledge acquisition is difficult, especially when the domain knowledge is not structured. In this paper a framework based on machine learning is proposed in order to generate a rule-base for signal analysis in the case of anesthesia monitoring. During surgery, clinical parameters are measured. From training samples, rules for a knowledge-based system can be learned that describe alarm situati...
