This research is done with an aim to compare the quality of housing in the two common appartment form on the rendering of main indexes of housing quality through two pre-designed neighbourhoods of Haft HozNeighborhood and the first phase of Ekbatan residential complex in the city of Tehran. Indexes of housing quality are extracted from the internal and external resources and are subjected to qu...

today, there arevarious statistical models for the discrete simulation of the rainfall occurrence/non-occurrence with more emphasizing on long-term climatic statistics. nevertheless, the accuracy of such models or predictions should be improved in short timescale. in the present paper, it is assumed that the rainfall occurrence/non-occurrence sequences follow a two-layer hidden markov model (hm...

during a funistic survey of natural enemies of pomegranate aphid (aphis punicae pass.) in kashmar region, specimens of an endoparasitoid belonging to family cecidomyiidae was collected which identified as endaphis perfidus keiffer 1896. endaphis perfidus is one of the six species in the genus endaphis in the world that was previously reported from acer aphid, drepanosiphum planatoides (schrank)...

The forecasting process of real-world time series has to deal with especially unexpected values, commonly known as outliers. Outliers in time series can lead to unreliable modeling and poor forecasts. Therefore, the identification of future outlier occurrence is an essential task in time series analysis to reduce the average forecasting error. The main goal of this work is to predict the occurr...

A binary sequence of zeros and ones is called a (d, k)-sequence if it does not contain runs of zeros of length either less than d or greater than k, where d and k are arbitrary, but fixed, non-negative integers and d < k. Such sequences find an abundance of applications in communications, in particular for magnetic and optical recording. Occasionally, one requires that (d, k)-sequences do not c...

Abstract. The time series of normalized difference vegetation index (NDVI) and interferometric coherence extracted from optical Synthetic Aperture Radar (SAR) images, respectively, have strong responses to sudden landslide failures in vegetated regions, which is expressed by a increase or decrease the values NDVI coherence. Compared with sensors, SAR sensors are not affected cloud daylight cond...

This paper investigates association between portfolio returns and higher-order systematic co-moments at different timescales obtained through wavelet multiscalinga technique that decomposes a given return series into different timescales enabling investigation at different return intervals. For some portfolios, the relative risk positions indicated by systematic co-moments at higher timescales ...
