This paper proposes a rapid detection algorithm of a salient region for music video browsing system, which can be applied to mobile device and digital video recorder (DVR). The input music video is decomposed into the music and video tracks. For the music track, the music highlight including musical chorus is detected based on structure analysis using energy-based peak position detection. Using the emotional models generated by SVM-AdaBoost learning algorithm, the music signal of the music videos is classified into one of the predefined emotional classes of the music automatically. For the video track, the face scene including the singer or actor/actress is detected based on a boosted cascade of simple features. Finally, the salient region is generated based on the alignment of boundaries of the music highlight and the visual face scene. First, the users select their favorite music videos from various music videos in the mobile devices or DVR with the information of a music video's emotion and thereafter they can browse the salient region with a length of 30-seconds using the proposed algorithm quickly. A mean opinion score (MOS) test with a database of 200 music videos is conducted to compare the detected salient region with the predefined manual part. The MOS test results show that the detected salient region using the proposed method performed much better than the predefined manual part without audiovisual processing.

Home economics education professional knowledge consists of empirical interpretive critical science component. Thus it is imperative that the alternative research perspectives be used to gain certain knowledge for the profession of home economics education. In human inquiry and education there is a growing concern that the dominant research paradigm positivist natural science model is inadequate to address the phenomena constructed by persons. However, Home economics education has not examined and almost utilized alternative research perspectives. This review will probe research logic and resecrach methodology of qualitative inquiry within home economics education and highlight the shift from positivism to post-positivism.

In this paper, different curvature-rates are controlled to highlight the characteristic of viscoplastic response in cyclic bending tests. The curvature-ovalization apparatus, which was designed by Pan et al. (1998), is used for conducting the curvature-controlled experiments on thin-walled tubular specimens for AISI 304 stainless steel under cyclic bending. The results reveals that the faster the curvature-rate implies, the fast degree of hardening of the metal tube. However, the ovalization of the tube cross-section increases when the curvature-rate increases.

This paper deals with a problem on the selection of alternative tools in a flexible manufacturing system (FMS) where a lot of tools are required to produce a large variety of product items. An approach using branch and bound method is proposed to minimize a total number of tools required through the optimal use of the alternative tools. In this approach, tools are initially divided into tool subgroups based on graph theory for the purpose of the effective search of the optimal solution. A small example is also presented to highlight the effectiveness of the proposed approach.

This is a experiment about change of highlight point by HBU and HLM of auxiliary function of gradation in color scanner. The result of change - over by HBU and HLM are summerized as follows. Therefore, the determination for the effective point and the amount of HBU and HLM are decided by the Table 1 and Table 2.

This paper intends to highlight the effect of the third-body in an inclined orbit on a spacecraft orbiting the primary mass. To achieve this goal, a new origin of coordinate is introduced in the primary and the X-axis toward the node of the spacecraft. The disturbing function is expanded up to the second order using Legendre polynomials. A double-averaged analytical model is exploited to produce the evolutions of mean orbital elements as smooth curves.

In this paper, we firstly introduce the class of C^*-algebra valued symmetric spaces and utilize the same to prove our fixed point results. We furnish an example to highlight the utility of our main result. Finally, we apply our result to examine the existence and uniqueness of a solution for a system of Fredholm integral equations.

The effect of heat treatment on membrane permeabilities of yeast's cells was studied, the amounts of efflux out of yeast cells were put to analysis, and fraction survival was also counted by viable plate counting method. Effects of nutritional substances on thermally injured yeast cells were also investigated under the highlight of reabsorption mechanism, then the relationship between permeability and surviving action in injured yeast cells are discussed.
