An adaptive filter for noise cancellation of ECG Is proposed. An adaptive noise canceller using the least mean squares algorithm Is used to reduce unwanted noise. An adaptive filter for nolse cancella lion minimizes the mean-square error between a primary input and a reference input. A primary input is the noisy ECG, and a reference input is a noise that Is correlated in some way with the noise in the primary input or a signal that is correlated only with ECG in the primary input.

Hundreds of Steller sea lions, Eumetopias jubatus, migrate from Sakhalin and the northern Kuril Islands to Hokkaido in Japan every winter. During this migration, they may use their roaring sounds to navigate and to maintain their groups. We recorded the roars of wild Steller sea lions that had landed on reefs on the west coast of Hokkaido, and those of captive sea lions, while making video recordings. The fundamental frequency ($F_0$), Formant frequency ($F_1$), pulse repetition rate (PRR), and duration of syllables (T) were analyzed using a sonagraph. $F_0$, $F_1$, and PRR of the roars emitted by captive sea lions increased in the order male, female. By contrast, the $F_1$ of wild males was lower than that of females, while the $F_0$ and PRR of wild males and females did not differ statistically. These results suggest regional differences between the five groups showed that.

Hundreds of Steller sea lions, Eumetopias jubatus, migrate from Sakhalin and the northern Kuril Islands to Hokkaido every winter. During this migration, they may use their roaring sounds to navigate and to maintain their groups. We recorded the roars of wild Steller sea lions that had landed on reefs on the west coast of Hokkaido, and those of captive sea lions, while making video recordings. A total of 300 roars of wild sea lions and 870 roars of captive sea lions were sampled. The fundamental frequency ($F_0$), formant frequency ($F_1$), pulse repetition rate (PRR), and duration of syllables (T) were analyzed using a sonagraph. $F_0$, $F_1$, and PRR of the roars emitted by captive sea lions increased in the order male, female, and juvenile. By contrast, the $F_1$ of wild males was lower than that of females, while the $F_0$ and PRR of wild males and females did not differ statistically. Moreover, the $F_0$ and $F_1$ frequencies for captive sea lions were higher than those of wild sea lions, while PRR in captive sea lions was lower than in wild sea lions. Since there was a linear relationship between body length and the $F_0$ and $F_1$ frequencies in captive sea lions, the body length distribution of wild sea lions could be estimated from the $F_0$ and $F_1$ frequency distribution using a regression equation. These results roughly agree with the body length distribution derived from photographic geometry. As the volume of the oral cavity and the length of the vocal cords are generally proportional to body length, sampled roars can provide useful information about a population, such as the body length distribution and sex ratio.

This study, after analyzing 2019 Cannes Lion winners, suggests five creative trends. It was found that these global five creative trends are multi-sensory experience, integration between data and creativity, real humanism, brand activist, and consideration for socially disadvantaged. Not only visual impact or stimulus, but audio or scent could be utilized in an effort to stimulate consumers and promote brands. In 2019 Cannes Lions advertising campaigns which sought to find consumer insight through data and apply it to creativity received applause from Cannes Lions judges. In addition, advertising campaigns based on real humanism suggest that attitudes are best changed through positive experiences. Nike's 'Dream Crazy' campaign is a good example which shows a company's philosophy and brand purposes. Brands are becoming activists and are being encouraged to take real action, and for good reason. Lastly, projects such as Ikea's 'ThisAbles' and Microsoft's 'Xbox Adaptive Controller' are contrived for the socially disadvantaged.

As the very important artistic elements expressing a visual image, the color has been increasing the power of expression. But the relationship between the remarkable peculiarity of colors in accordance with other artistic elements inside the picture plane makes difficult to express an effective expression of color. In the adaptation of color as well as artistic style between & by W. Disney co. is very different each other in the manner of expression. By revealing the difference of the practical use of color and it's principle of those two works, I want to formulate a suitable use of color. In this paper, focus on how to active application of color in relationship between other artistic element and expressive peculiar of color. A right is not only the dominant component in color, but contrast also. A contrast is the most considerable element for modeling order. To emphasize expressive peculiar of color, an artist control artistic element properly and can make expressive energy of brightness & shape.

The purpose of this study is to investigate the metatheatricality of Harris' plays marked by the device of 'play-within-a-play' - Androcles and the Lion, Arkansaw Bear, and Punch and Judy. In his metatheatrical plays Harris shows that characters perform for themselves and others. The framework that inner performance is going on within the outer frame play is formed on the stage, and this device reminds the audience in the seats that they are representing reality but that they are only in the middle of performing on the stage. Based on this point of view, this study explores fictionality of character, and play. In Androcles and the Lion, the most-performed children's play in America, the metatheatrical elements are shown in the style of commedia dell'arte, which attacks the rigidity of characters' identity in the Roman society. Another well-known children's play, Arkansaw Bear consists of realistic frame play and fantastic inner play in the mind of a girl, both of which function as a mirror each other and help to sustain aesthetic distance to death and reality on the stage. In Punch and Judy, the structure of frame play and inner puppet play reminds that what's going on in the play is just a fictional play and reflects history of children's puppet show. Harris' unique metatheatricality, the heightened awareness of his own artistic medium, offers children educational opportunity to learn about how a play is performed on the stage and contributes to convey mature theme through children's imaginary participation in the process of playmaking on the stage.

The nanocomposites containing graphene oxide (GO) were prepared in order to improve the mechanical properties of poly(methyl methacrylate)/aluminum hydroxide (PMMA/AH) composites. GO was prepared from graphite by oxidation of Hummers method followed by exfoliation with thermal treatment. The surface of GO was modified by oxygen plasma in various exposure times from 0 to 70 min to improve interfacial compatibility. Compared with PMMA/AH composites, the nanocomposites containing GO modified with oxygen plasma for the exposure time up to 50 min showed significant increases in flexural strength, flexural modulus, Rockwell hardness, Barcol hardness, and Izod impact strength. The morphology of fracture surface showed an improved interfacial adhesion between PMMA/AH composites and GO, which was properly treated with oxygen plasma. The mechanical properties of nanocomposites were deteriorated by increasing the content of GO above 0.07 phr due to the nonuniform dispersion of GO.

An experimental study is carried out to investigate the performance of the cutting tool regarding the insert wear, surface roughness, cutting forces, cutting power and material removal rate of three coated carbides GC2015 (TiCN-Al₂O₃-TiN), GC4215 (Al₂O₃-Ti(C,N)) and GC1015 (TiN) during the dry turning of AISI4140 steel. For this purpose, a Taguchi design (L₉) was adopted for the planning of the experiments, the effects of cutting parameters on the surface roughness (R_a), tangential cutting force (F_z), the cutting power (P_c) and the material removal rate (MRR) were studied using analysis of variance (ANOVA), the response surface methodology (RSM) was used for mathematical modeling, with which linear mathematical models were developed for forecasting of R_a, F_z, P_c and MRR as a function of cutting parameters (V_c, f, and a_p). Then, Multi-Objective Ant Lion Optimizer (MOALO) has been implemented for multi-objective optimization which allows manufacturers to enhance the production performances of the machined parts. Furthermore, in order to characterize and quantify the flank wear of the tested tools, some machining experiments were performed for 5 minutes of turning under a depth of 0.5 mm, a feed rate of 0.08 mm/rev, and a cutting speed of 350 m/min. The wear results led to a ratio (V_B-GC4215/V_B-GC2015) of 2.03 and (V_B-GC1015/V_B-GC2015) of 4.43, thus demonstrating the efficiency of the cutting insert GC2015. Moreover, SEM analysis shows the main wear mechanisms represented by abrasion, adhesion and chipping.
