We apply the Artificial Immune System (AIS) technology to the Collaborative Filtering (CF) technology when we build the movie recommendation system. Two different affinity measure algorithms of AIS, Kendall tau and Weighted Kappa, are used to calculate the correlation coefficients for this movie recommendation system. From the testing we think that Weighted Kappa is more suitable than Kendall t...

For a given bivariate survival function F, we study the relations between the set of the level curves of F and the Kendall distribution. Then we characterize the survival models simultaneously admitting a specified Kendall distribution and a specified set of level curves. Attention will be restricted to exchangeable survival models. 2009 Elsevier Inc. All rights reserved.

Diurnal Temperature Range (DTR) is one of global warming indicator which using only daily minimum temperature (TMin) and maximum (TMax) for calculation. The study aims 1) to analyse trend TMax, TMin DTR over the early period 21st century (1987 - 2020) 2) forecast mid late (2021 2040 2041-2100) MIROC5 (rcp85) model, cooperated with EQM Statistical downscaling method. TMin, trends all periods wer...

Tourism activities are highly dependent on climatological conditions. The suitability of tourism destinations is investigated by using a Climate Index (TCI) that frequently used researchers. TCI varies between 0 and 100 created temperature, relative humidity, sunshine duration, wind precipitation data. For TCI, for ideal extremely unfavorable conditions tourism. In this study, the meteorologica...

The study aims to identify long-term trends in the changes of drought occurrences using Mann-Kendall (MK) test and Theil-Sen estimator. Trend research was carried out on example catchment area Upper Note? River, which covers an agricultural Poland with some lowest water reserves. meteorological droughts were identified based Standardized Precipitation Index (SPI), while hydrological determined ...

Based on energy balance theory, using Theil–Sen median trend analysis and the Mann–Kendall test, this research studied applicability of complementary theory evapotranspiration (ET) over Ningxia in Upper Reaches Yellow River with MOD16 ET product measured data meteorological stations, based which drought index (EDI) was proposed for first time. Moreover, usability EDI also verified its influenci...

One of Amartya Sen’s most distinctive claims, and perhaps also one of his most controversial, is that there is an altruistic attitude toward others that does not make sense within the terms of rational choice theory, however broadly that theory is construed. He describes this attitude as one of “commitment” to others, contrasting itwith egoismandalsowith adistinct altruistic attitude he calls “...

The design and implementation of an interactive spot noise algorithm is presented. Spot noise is a technique which utilizes texture for the visualization of ow elds. Various design tradeoos are discussed that allow an optimal implementation on a range of high end graphical workstations. Two applications are given: the steering of a smog prediction simulation and browsing a very large data set r...

We deene a speciication language called`timed CRL'. This language is designed to describe communicating processes employing data and time. Timed CRL is the successor of CRL 17]. It diiers in two main aspects. It is possible to make explicit reference to time using a newàt' operator; p,t is the process p where the rst action must take place at time t. Furthermore, a distinction has been made bet...
