In heartbeat detection tasks based on the Method of Constant Stimuli (MCS), subjects judge the simultaneity between their heartbeats and stimuli presented at six intervals ranging from 0 to 500 ms after the R-waves on an electrocardiogram. Because research suggests that subjects do not perceive stimuli at 0 or 500 ms as simultaneous, individual performance was indexed with quadratic trend analy...

One of the common quality parameters for drinking water is residual aluminium. High doses of residual aluminium in drinking water or water used in the food industry have been proved to be at least a minor health risk or even to increase the risk of more serious health effects, and cause economic losses to the water treatment plant. In this study, the trend index is developed from scaled measure...

In October 2013 the MARLANT N02OR team of DRDC, Centre for Operational Research and Analysis (CORA) was asked by Commander Canadian Fleet Atlantic (COMCANFLTLANT) to collaborate with the Commanding Officer (CO) and Weapons Officer (WpnsO) from HMCS Charlottetown on a high-level analysis of the change – if any – in the scope and complexity of the fleet’s operations over time. More concisely, the...

This thesis describes research work within the theme of trend mining as applied to social network data. Trend mining is a type of temporal data mining that provides observation into how information changes over time. In the context of the work described in this thesis the focus is on how information contained in social networks changes with time. The work described proposes a number of data min...

In many applications, the mean of a response variable can be assumed to be a nondecreasing function of a continuous predictor, controlling for covariates. In such cases, interest often focuses on estimating the regression function, while also assessing evidence of an association. This article proposes a new framework for Bayesian isotonic regression and order-restricted inference. Approximating...

dimension in the co-citation literature, to date it has not been incorporated into the analogous process of link analysis on the Web. In this paper, we discuss several aspects and uses of the time dimension in the context of Web information retrieval. We describe the ideal case— where search engines track and store temporal data for each of the pages in their repository, assigning timestamps to...

The purpose of this study was to analyze the trend of scientific articles in the field of agricultural education. The statistical population of the study consisted of all agricultural education articles published in three scientific journals from the years 2013 to 2017 (N = 198). All the articles were studied. SPSS and EXCEL software used to analyze the data. The findings showed that the journa...

the aim of this research is the study of trends in annual precipitation changes in some selected stations located in the sefid rood basin, applying the man-kendall non-parametric technique. the method is one of the most frequently used non-parametric techniques for trend analysis of precipitation on an annual scale. six synoptic stations located in the sefid rood basin were selected for the ana...
