For a general regression model with n independent observations we consider the variance of the estimate of a quantity of interest under two scenarios. One scenario is where all the parameters are estimated from the data, the other scenario is where a subset of the parameters are assumed known at their true values and the remaining parameters are estimated. We focus on quantities of interest whi...

Concatenative speech synthesis is increasing in popularity, as it offers higher quality output than previous formant synthesisers. However, it is based on recorded speech units, concatenative synthesis offers a lesser degree of parametric control during resynthesis. Consequently, adding pragmatic effects such as different speaking styles and emotions at the synthesis stage is fundamentally more...

INTRODUCTION Agitated Depression and Bipolar mixed states combine depressive and manic symptoms, reflecting severe forms of affective disorders with an increased suicide risk. These states have not been defined with adequate consensus and hence present a diagnostic and therapeutic challenge. In this study, we argue that both states are part of the bipolar spectrum rather than a distinct affecti...

Using computers to simulate human affective activities is a challenging work. After the analysis of human affective characters, this paper puts forward some artificial psychology models and mainly discusses a model based on HMM, and the concept of affective entropy which is used as the parameter index of constructing and evaluating individual characters of virtual human. This model considers hu...

In this paper we describe an approach for using semantic annotations of process models to support business process benchmarking. We show how semantic annotations can support the preparation of process benchmarking data by adding machine-processable semantic information to existing process models without modifying the original modeling language, conduct semantic analyses for the purpose of perfo...

Artificial neural networks (ANNs) are processors that are trained to perform particular tasks. We couple a computational ANN with a simulated affective system in order to explore the interaction between the two. In particular, we design a simple affective system that adjusts the threshold values in the neurons of our ANN. The aim of this paper is to demonstrate that this simple affective system...

in order to investigate the effect of adding fennel powder (foeniculum vulgare) in starter diet on performance, immunity system and biometric parameters of holstein calves, 30 holstein calves (15 males and 15 females) with birth weight of 40±0.5 kg were used in a completely randomized design. experimental diets were: 1. starter without fennel powder (control), 2. starter containing 0.4% fennel ...

BACKGROUND Somatic, but not cognitive-affective, symptoms of depression have been associated with reduced heart rate variability (HRV), and with poor prognosis in cardiovascular patients. However, factors concomitant with cardiovascular diseases may confound the relationship between somatic symptoms of depression and reduced HRV. Therefore, this study examined whether reduced HRV was differenti...

1. For consistency and to avoid confusions, the term dimension is used across PCA, CFA, and RSM analyese. Validity evidence is provided for a Persian blog attitude questionnaire (P-BAQ). P-BAQ was administered to 565 Iranians and factor analysis and rating scale model identified affective, behavioral, and perseverance, and confidence dimensions underlying the data. P-BAQ's validity argument was...
