FORECASTING THE CROPS FROM THE WEATHER

the effect of traffic density on the accident externality from driving the case study of tehran

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...

Forecasting Techniques in Crops

Introduction Reliable and timely forecasts provide important and useful input for proper, foresighted and informed planning, more so, in agriculture which is full of uncertainties. Agriculture now-adays has become highly input and cost intensive. Under the changed scenario today, forecasting of various aspects relating to agriculture are becoming essential. But in-spite of strong need for relia...

The Role of Diagnosis in Weather Forecasting

Diagnostic meteorology is intertwined with the role of humans in forecasting, as discussed in D86a. Truly, weather forecasting is part of the science of meteorology, but recent history has created the illusion of a dichotomy between them. This paper attempts to illustrate how we envision diagnostic meteorology should proceed. In the process, we shall provide a basis for understanding why the ga...

Decision Tree for the Weather Forecasting

Predicting the classification of data in a suitable class is a challenging task. It depends on various factors to predict the dependent variables. Since decision tree evaluation can be quantified and it is simple to use, so a model using decision tree has been proposed by the author to predict the event like fog, rain and thunder by inputting average temperature, humidity and pressure. Which ca...
