The effectiveness of valence and arousal features in whispered speech emotion classification is studied.Finally,the Gaussian mixture model is studied and applied to whispered speech emotion recognition. The cognitive performance is also considered in emotion recognition so that the recognition errors of whispered speech emotion can be corrected.Based on the cognitive scores,the emotion recognition results can be improved.The results show that the formant features are not significantly related to arousal dimension,while the short-term energy features are related to the emotion changes in arousal dimension.Using the cognitive scores,the recognition results can be improved.展开更多

Based on the findings, a method is suggested for emotional space formation and emotional inference that enhance the quality and maximize the reality of emotion-based personalized services. In consideration of the subjective tendencies of individuals, AHP was adopted for the quantitative evaluation of human emotions, based on which an emotional space remodeling method is suggested in reference to the emotional model of Thayer and Plutchik, which takes into account personal emotions. In addition, Sugeno fuzzy inference, fuzzy measures, and Choquet integral were adopted for emotional inference in the remodeled personalized emotional space model. Its performance was evaluated through an experiment. Fourteen cases were analyzed with 4.0 and higher evaluation value of emotions inferred, for the evaluation of emotional similarity, through the case studies of 17 kinds of emotional inference methods. Matching results per inference method in ten cases accounting for 71% are confirmed. It is also found that the remaining two cases are inferred as adjoining emotion in the same section. In this manner, the similarity of inference results is verified.展开更多

Thus, the objective of this research was to develop a tool capable to make possible the simulation and optimization of the continuous flow furrow irrigation performance, making successive simulations of the advance phase and respective prognostics of the performance parameters of the irrigation system. The proposed model is denominated SASIS, ＂Software Applied to Simulation of the Surface Irrigation＂, and had its validation tested for different field conditions. In this paper, the simulation and the optimization of the furrow irrigation by the model SASIS are evaluated regarding to the spatial （4） and temporal （0） weighted factors, which account for the nonlinear variation in the surface and subsurface flow profiles. The analysis of the sensitivity of simulation of the advance phase in the irrigation identified ranges of combinations between spatial and temporal weighted factors of the surface and subsurface flow profiles, resulted in acceptable discrepancies between simulated and measured advance time. Also it was verified that conjugated effect of these weighted factors on the simulation of the advance phase was greater than the effect of the temporal weighted factor. The model presents effective mechanisms in the accomplishment of countless simulations, in a discharge strip understood between the minimum and the maximum allowable values, aiming to determine the relationship between discharge and water application efficiency, deep percolation and runoff rates, and consequently to optimize the performance of the furrow irrigation systems with continuous flow.展开更多

There are a wide variety of pet products and services, similar to those available to the human being and note that pet care industry address the posts to pet owners and the messages intend to motivate the emotions and feelings for the animals, in a sentimental anthropomorphism process. The marketing messages are similar to those of products shaped to induce a person to buy luxury products. Market social interaction is driven by both the human-animal bond and the pet care market campaigns advertisement. In many situations, people interact with pet as a person or a member of the family, as a unique and special living being. The authors conclude that in families which people and animal interacts, new meanings emerge from this contact.展开更多

The aim of this study is to analyze engagement in a group of 132 high school teachers from various schools in the private sector and identify its relationship with the commitment variable. The results of the work of this group in three dimensions are presented in this study： vigor, dedication, and absorption; the correlation data are also presented with organizational commitment in three dimensions： affective, normative and temporal （or continuity）. With these results the aim is to find predictive evidence among teachers who score significantly in the three dimensions of engagement and the three dimensions of commitment.展开更多

First, according to Lefebvre, representations of space are created with violence for the purpose of accumulating capital. On the other hand, representational space is directly lived or affectively felt, opened up by inhabitants＇ imagination. In addition, Lefebvre points out that in abstract space, representational space will be invaded by representations of space. In The Bridge, Crane＇s affective experience with the Brooklyn Bridge or the subway indicates that he treats New York as a representational space. Besides, Crane expresses his concern for how capitalism has encroached on it. It would seem that Crane has followed Lefebvre＇s line of thinking in The Bridge. However, it is actually a specious analysis because both the Brooklyn Bridge and the subway are representations of space. And in this long poem, Crane feels the urban space through history, which plays a key role in creating representations of space. Thus, we can conclude that Crane is actually taking ＂a walk in between＂ in The Bridge. With his imagination, Crane has combined representations of space and representational space into his own poetic vision.展开更多

However, the annotation in the dimensional affect space usually takes the form of a continuous real value which has an ordinal property. The aforementioned methods do not focus on taking advantage of this important information. Therefore, we propose an affective rating ranking framework for affect recognition based on face images in the valence and arousal dimensional space. Our approach can appropriately use the ordinal information among affective ratings which are generated by discretizing continuous annotations.Specifically, we first train a series of basic cost-sensitive binary classifiers, each of which uses all samples relabeled according to the comparison results between corresponding ratings and a given rank of a binary classifier. We obtain the final affective ratings by aggregating the outputs of binary classifiers. By comparing the experimental results with the baseline and deep learning based classification and regression methods on the benchmarking database of the AVEC 2015 Challenge and the selected subset of SEMAINE database, we find that our ordinal ranking method is effective in both arousal and valence dimensions.展开更多
