{"title":"Emotion Discrimination of Amusement Based on Three-Dimensional Data of Body Movements","authors":"Huawei Zhang, Tsuyoshi Takahashi, Y. Kageyama, M. Nishida","doi":"10.5188/ijsmer.23.189","DOIUrl":"https://doi.org/10.5188/ijsmer.23.189","url":null,"abstract":"An important problem associated with the progression of aging in society is the improvement of quality of life (QOL). If we can maintain or improve the QOL for individuals, including the elderly, this will contribute not only to the revitalization and stability of society [1], but also to the reduction of social costs such as nursing care and medical expenses [2]. Therefore, a living support system, such as an acceptable living environment and health monitoring system, is required. There are currently no imaging systems capable of automatically and quantitatively evaluating the factors that improve individual QOL and the intensity thereof in real time. Human QOL and \"laughs/smiles\" are closely related. Individuals who laugh every day exhibit better health and improved psychological state. In addition, calmness is recognized in animal-assisted therapy and is known to contribute to the improvement of QOL [3]. Based on these fi ndings, it is considered that maintaining or improving QOL is possible in an environment where amusement and calm are encouraged. Using visual images, it is difficult to distinguish between natural facial expressions and those shown intentionally; however, there is no example for defining and observing calmness [4]. The report on emotions by Miyasaka et al. focused on changes in facial skin temperature and accompanying blood fl ow [5] with emphasis on nose temperature, while Kumamoto et al. reported on a method for evaluating stress [6]. There is no system that considers an example of integrated visible and infrared images to evaluate attitude changes. In our previous studies, we showed that movement features of the lip change as the subject's feelings (state of no stress, no vision, etc.,) and physical conditions change, while acquiring motion data on the movement of the lips. We clarifi ed that the presence or absence of psychological changes can be discriminated by the movement features of the lip when amusement is evoked [7]. Vertical motion was observed in the head and shoulders when a strong emotion such as \"amusement\" was expressed. Nonverbal communication, including body movements, contributes to the transmission of approximately 65% of information [8]. That is, combining facial expression, movement features of the lips, and movement features of the body is useful for the recognition and quantification of emotions. In this paper, we develop elementary technologies of multiimage processing systems that can recognize multiple emotions by focusing on the basic study of body movement features to recognize emotion. This study aims to verify whether emotions of amusement can be detected with body movement features by using Microsoft Kinect. Although there are individual differences, this study aims to demonstrate the possibility of using body movement features as indicators of the strength of emotional expressions. Specifi cally, we use the XBOX ONE KINECT SENSOR (Microsoft Corp, Kinect for short), which focuses on nonverba","PeriodicalId":14339,"journal":{"name":"International journal of the Society of Materials Engineering for Resources","volume":"285 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75196139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The NaCl penetration into agar gel sprayed with NaCl on the surface was evaluated using impedance. As the measured position of the electrode moves downward, a longer time is needed to obtain a constant impedance value. Measurement of the chloride concentrations in the model food that had been cut into four pieces (surface, upper, middle, and lower parts) revealed an extremely strong relation between the equilibrium period of the impedance value and the inner chloride concentrations of the model. Results con fi rmed that a similar impedance value was obtained if the concentration of NaCl sprinkled on the top of the gels was the same irrespective of points measured using the electrode. These results demonstrate that this impedance measurement method using an LCR meter is useful for real-time monitoring of NaCl osmosis in the food interior.","PeriodicalId":14339,"journal":{"name":"International journal of the Society of Materials Engineering for Resources","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87261492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These deposits initially consist of disseminated sulfide minerals in a rock matrix, but near-surface weathering oxidizes the sul fi des and dissolves metals from the residual mass. These leached metals in solution percolate downward and are often reprecipitated in an enrichment zone overlying unreacted sulfide protore. The near-surface weathered, oxidized portion of the deposit corresponds to the oxidized region (high oxidation potential), while the non-oxidizing reduced enrichment zone corresponds to the reduced Copper sul fi de from ore deposits and recycled copper from collected wastes are the two main resources for the production of copper metal. Thermodynamic calculations can be used to serve as a guide for characterization of ore deposits and their mineralogy as well as for process development by mineral processing and by waste separation. The concentrated ore and separated waste can then be processed by pyro- and/or by hydro-metallurgical operations. Such operations may be controlled by oxidation-reduction potential, temperature, complexing reagents (gas, solid or dissolved species), oxidant- reductant, and mass of components. Commonly used stab ility diagrams for aqueous system include speciation (counting alpha) and E H -pH (Pourbaix) diagrams and, for non-aqueous systems, are partial pressure (Kellogg), binary and ternary phase, and Ellingham diagrams. For multicomponent systems, the appropriate approach for the construction of the stability diagram is to use a complete mass balance approach rather than draw the equilibrium line between two adjacent species. Not limited to two variables, a three- dimensional diagram can also be constructed. This paper illustrates the use of stability diagrams for investigating and interpreting how operation variables are important with a focus on extractive metallurgical operations to produce copper. Industria l operation conditions are marked on the diagrams.","PeriodicalId":14339,"journal":{"name":"International journal of the Society of Materials Engineering for Resources","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90144389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These materials are usually fed into the grizzly to remove the soils attached on their surfaces. At present, grizzly-under-materials (GUM) does not satisfy the required standard value for soil contents. In 2009, we proposed the equipment to remove the soils from GUM. This equipment was able to reduce the soil content in the GUM, but the ef fi ciency was not so high. Then, in 2013, a process of re-designing this equipment was carried out; where a vibration device was added to reduce the pipe inclination angle and to increase the processing time of materials inside the apparatus. The equipment performance had an opposite behavior from 2009 ’ s experimental results to 2013 ’ s experiment results, when the water content in the GUM was changed from 3% to 5%. That is, it was necessary to analyze the main factors that in fl uence on equipment performance. In this study, the experiments were carried out with changing the water contents. It was found through this research that soil reduction activity, using the screenless separation equipment not only depends on the soil particle distribution (% of clay and silt) contained in GUM and the moisture content in the soil when is mixed with GUM.
