    Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Rainfall is very important parameter in hydrological model. Many techniques and models have been developed for rainfall forecasting. This study present a method of rainfall forecasting by developing an ANN- based model using major weather variables such as dry bulb temperature, wet bulb temperature, relative humidity, pan evaporation, vapour pressure as inputs while the rainfall as the target output. As part of the ANN model development procedures, the data sets of 11956 data in the study area was partitioned into two parts with 70% of the entire data sets used as the training data while the remaining 30% used as the testing and the validation data. The proposed model has been able to predict values with suitable results. For the evaluation of the results and the ability of the developed prognostic models, appropriate statistical indexes such as the coefficient of determination (R2), the Root mean square error (RMSE), Mean square error (MSE), Nash-Sutcliffe efficiency (EF), Akaike information criteria (AIC), Bayesian information criteria (BIC) were used. The findings from this analysis showed that the ANN model 5-5-3-1 provides satisfactory results based on statistical indexes. 84 pp. Englisch.

De nombreuses techniques et modèles ont été développés pour la prévision des précipitations. Cette étude présente une méthode de prévision des précipitations en développant un modèle basé sur l'ANN utilisant les principales variables météorologiques telles que la température du bulbe sec, la température du bulbe humide, l'humidité relative, l'évaporation de la cuvette, la pression de vapeur comme données d'entrée, tandis que les précipitations constituent la sortie cible. Dans le cadre des procédures de développement du modèle ANN, les ensembles de 11956 données de la zone d'étude ont été divisés en deux parties, 70% de l'ensemble des ensembles de données étant utilisés comme données d'entraînement tandis que les 30% restants sont utilisés comme données de test et de validation. Le modèle proposé a été en mesure de prédire les valeurs avec des résultats appropriés. Pour évaluer les résultats et la capacité des modèles pronostiques développés, des indices statistiques appropriés tels que le coefficient de détermination (R2), l'erreur quadratique moyenne (RMSE), l'erreur quadratique moyenne (MSE), l'efficacité de Nash-Sutcliffe (EF), les critères d'information d'Akaike (AIC), les critères d'information bayésiens (BIC) ont été utilisés. Les résultats de cette analyse ont montré que le modèle ANN 5-5-3-1 fournit des résultats satisfaisants sur la base des indices statistiques.

    Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Niederschlag ist ein sehr wichtiger Parameter in hydrologischen Modellen. Viele Techniken und Modelle wurden für die Niederschlagsvorhersage entwickelt. In dieser Studie wird eine Methode zur Niederschlagsvorhersage durch die Entwicklung eines ANN-basierten Modells vorgestellt, das die wichtigsten Wettervariablen wie Trockenkugeltemperatur, Feuchtkugeltemperatur, relative Luftfeuchtigkeit, Pfannenverdunstung und Dampfdruck als Eingaben und die Niederschlagsmenge als Zielausgabe verwendet. Im Rahmen der Entwicklung des ANN-Modells wurde der Datensatz von 11956 Daten im Untersuchungsgebiet in zwei Teile aufgeteilt, wobei 70 % des gesamten Datensatzes als Trainingsdaten und die restlichen 30 % als Test- und Validierungsdaten verwendet wurden. Das vorgeschlagene Modell war in der Lage, Werte mit geeigneten Ergebnissen vorherzusagen. Zur Bewertung der Ergebnisse und der Fähigkeit der entwickelten Prognosemodelle wurden geeignete statistische Indizes wie das Bestimmtheitsmaß (R2), der mittlere quadratische Fehler (RMSE), der mittlere quadratische Fehler (MSE), die Nash-Sutcliffe-Effizienz (EF), die Akaike-Informationskriterien (AIC) und die Bayes'schen Informationskriterien (BIC) verwendet. Die Ergebnisse dieser Analyse zeigten, dass das ANN-Modell 5-5-3-1 auf der Grundlage der statistischen Indizes zufriedenstellende Ergebnisse liefert. 84 pp. Deutsch.

    Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A precipitação é um parâmetro muito importante no modelo hidrológico. Foram desenvolvidas muitas técnicas e modelos para a previsão da precipitação. Este estudo apresenta um método de previsão da precipitação através do desenvolvimento de um modelo baseado em RNA que utiliza as principais variáveis meteorológicas, tais como a temperatura de bolbo seco, a temperatura de bolbo húmido, a humidade relativa, a evaporação da panela e a pressão de vapor como entradas, enquanto a precipitação é o resultado pretendido. Como parte dos procedimentos de desenvolvimento do modelo ANN, os conjuntos de dados de 11956 dados na área de estudo foram divididos em duas partes, com 70% dos conjuntos de dados completos utilizados como dados de treino, enquanto os restantes 30% foram utilizados como dados de teste e validação. O modelo proposto foi capaz de prever valores com resultados adequados. Para a avaliação dos resultados e da capacidade dos modelos de prognóstico desenvolvidos, foram utilizados índices estatísticos adequados, como o coeficiente de determinação (R2), a raiz do erro quadrático médio (RMSE), o erro quadrático médio (MSE), a eficiência de Nash-Sutcliffe (EF), os critérios de informação de Akaike (AIC) e os critérios de informação bayesianos (BIC). Os resultados desta análise mostraram que o modelo ANN 5-5-3-1 fornece resultados satisfatórios com base em índices estatísticos. 80 pp. Portugiesisch.

Sono state sviluppate molte tecniche e modelli per la previsione delle precipitazioni. Questo studio presenta un metodo di previsione delle precipitazioni sviluppando un modello basato su RNA che utilizza le principali variabili meteorologiche come la temperatura del bulbo secco, la temperatura del bulbo umido, l'umidità relativa, l'evaporazione del pan e la pressione di vapore come input, mentre le precipitazioni come output target. Nell'ambito delle procedure di sviluppo del modello ANN, la serie di 11956 dati dell'area di studio è stata suddivisa in due parti: il 70% dell'intera serie di dati è stato utilizzato come dati di addestramento, mentre il restante 30% è stato utilizzato come dati di test e di validazione. Il modello proposto è stato in grado di prevedere i valori con risultati adeguati. Per valutare i risultati e la capacità dei modelli prognostici sviluppati, sono stati utilizzati indici statistici appropriati come il coefficiente di determinazione (R2), l'errore quadratico medio (RMSE), l'errore quadratico medio (MSE), l'efficienza di Nash-Sutcliffe (EF), i criteri di informazione di Akaike (AIC) e i criteri di informazione bayesiani (BIC).
