The Simpsons: An Uncensored, Unauthorized History

The Simpsons is among the so much winning exhibits to ever run on tv. From its first second on air, the series's wealthy characters, subversive issues, and layered humor resounded deeply with audiences either old and young who sought after extra from their leisure than what used to be being meted out on the time via the likes of complete condo, transforming into Pains, and relations concerns.

Handbuch Unterhaltungsproduktion: Beschaffung und Produktion von Fernsehunterhaltung

Das Feld der Beschaffung und Produktion von Unterhaltungsangeboten ist im Gegensatz zu Informationsangeboten bisher kaum erforscht. Der Band bietet einen strukturierten Überblick darüber, auf Grund welcher Mechanismen die Medien der Gesellschaft Unterhaltungsangebote präsentieren. Im Mittelpunkt stehen die Akteure, Marktstrukturen, Organisationsformen und Strategien in der Fernsehunterhaltungsbeschaffung und –produktion.

Narrativas Mediáticas

Los angeles lógica del entretenimiento es el gusto socialmente legitimado que otorga sentido a las estéticas mediáticas. Una estética que no sólo ofrece los angeles información como espectáculo sino que también crea modos especiales de narrar para cada medio de comunicación. En Narrativas mediáticas, Omar Rincón analiza los modos y las estruc

The Politics of Star Trek: Justice, War, and the Future

The megastar Trek franchise displays, conveys, and reviews upon the main philosophical tensions of the fashionable period. This publication info the way during which those tensions and controversies are manifested in superstar Trek throughout its iterations, arguing that megastar Trek deals an vital contribution to our knowing of politics within the smooth period.

2 shows sample images synthesized in these two color spaces. The undistorted one on the left is synthesized in RGB color space while the heavily distorted one on the right is reconstructed in HSI color space. Thus, we can get two conclusion remarks: (1) RGB images are generated by a digital imaging system, so the CRFs recovered from each color channel are very close to each other, as shown by the right figure in Fig. 4. Therefore, no color distortion can be observed while radiance map E recovered from these CRFs in a fusion way.

Quaternion-based edge detection and pattern matching are then implemented on segmentation results to locate glands. Consequently, the quantitative analysis is available based on the extracted glands. Rather than reading a large number of medical images all by themselves, doctors can provide diagnosis more efficiently and more accurately using the proposed automatic quantitative analysis of pathological signal. Keywords: IVF-ET, quantitative analysis, Quaternion, QSVD, k-means, color texture segmentation, color edge detection.

For example, we can use the pure quaternion represent color pixel , , . The multiplication between two pure quaternions , , and , , is computed as follow, · (2) where symbol ‘ ’ denotes dot product operator and ‘⊗’ denotes the cross product operator. Thus, HE staining medical images can be represented as a quaternion matrix, that is, each element of the matrix is formulated as a pure quaternion. Accordingly, all the color vector operations can be realized with the rules of quaternion algebra operations.
