En este documento se presentan de forma breve los principales usos de las estadísticas de precios de consumo, prestando especial atención a la predicción de la inflación mediante modelos econométricos. También se realizan algunas propuestas de cara a aumentar la utilidad del índice de...

Purpose – The objective of this work is to develop a model that can be used for simulation of different parameters including price, subjected to different control strategies. Design/methodology/approach – The entire supply chain can be modelled by combining the transfer function into a...

We review the past 25 years of time series research that has been published in journals managed by the International Institute of Forecasters (Journal of Forecasting 1982-1985; International Journal of Forecasting 1985-2005). During this period, over one third of all papers published in these...

Implementing control structures such as gates at suitable locations in the urban drainage network enables its improved utility by actively controlling and optimizing the flow during a flood event. The successful operation of the control structure is fully governed by the suitability and...

Space constraints in developed urban cities necessitate utilizing existing capacity of the drainage system for actively controlling and optimizing the flow during a flood event. This is mainly achieved by the use of non-structural control measures (in the form of suitable controllers and control...

One-dimensional indexed bilinear (BL) models are widely used for modeling non Gaussian time series. Extending BL models to multidimensional indexed (spatial) SBL one, yields a novel class of models which are capable of taking into account the important characteristic of non Gaussianity and...

A calculation method of radiant time factors is presented and the method is used to calculate radiant cooling load. Based on experimental data of total heat gain and total cooling loads collected within 24-h, radiant heat gain and radiant cooling load can be calculated through convection and...

We present a medium-scale dynamic factor model to estimate and forecast the rate of growth of the Spanish economy in the very short term. The intermediate size of the model overcomes the serious specification problems associated with large-scale models and the implicit loss of information of...

In view of system efficiency and environmental protection, it is of primary importance to harvest solar energy better and better for example by means of developing solar collectors. Mathematical modelling is the theoretically established tool for it, for example with using the collector transfer...

Using a time series method called 'transfer function', this paper examines the effect of terrorism on tourism in Turkey. The results indicate that there exists a negative but small impact of terrorism, which is observed within approximately one year. However, terrorist attacks in Turkey have...
