The tomb of Fu hao
No full textA fully intact Shang Dynasty Anyang phase (c.1300-1100 B.C.) tomb—Xiaotun M5 or better known as the tomb of Fu Hao—was discovered in the Anyang region of Henan province, China in 1976. Although only a 'medium' size burial by Shang standards, the huge quantity of yielded grave goods is unprecedented in Shang archaeology. The inscription 'fu hao' is seen on about half of the 210 ritual bronze vessels from the tomb, and this same name may be seen in the contemporaneous divination records (the oracle bone inscriptions) collected in other Shang sites. It is thus possible to identify the occupant of M5. Another bronze inscription from the tomb, 'si mu xin', further suggests that Fu Hao was one of the consorts of the Shang king Wuding. Many scholars have commented on aspects of this identification and the date of the tomb. This thesis incorporates a synthesis of the discussions along with descriptions of the tomb and its ccontents. The archaeological, art historical and palaeographical materials and their significance are considered in separate sections. An annotated translation of selected Fu Hao-related oracle bone inscriptions is included. In addition, a chapter is given to a new discussion on the placement of large vessels in the tomb — its spatial design principles and significance. The tomb of Fu Hao offers a rare opportunity for us to discern parallels in the Various complementary cultural subsystems of Shang, such as the oracular language and the bronze art, in a relatively enclosed context. In the conclusion, the Weberian model of patrimonialism is employed to propose a perspective of the tomb and its content in a cultural-political context.Arts, Faculty ofFine Arts, Department of, Department ofGraduat
Modelling galaxy and black hole evolution via DECODE: Discrete statistical sEmi-empiriCal mODEl
No full textIn a dark matter-dominated Universe, where structures grow hierarchically, galaxies are thought to live inside dark matter haloes with their evolution being intimately connected. In traditional models of galaxy evolution, galaxies build up their stellar mass via the interplay among several physical processes such as mergers, star formation and quenching, implying that all the observables characterizing galaxy evolution should be strictly linked to each other. These quantities include, for example, the galaxy stellar mass function, merger rates, star formation histories, satellite abundances and intracluster light. The failure in simultaneously fitting distinct observational probes may be attributed to shortcomings in the underlying modelling, or to disagreements in different data sets. Indeed, the systematic errors affecting observations still prevent universal and uniform measurements of, for instance, the stellar mass functions and the star formation rates, inevitably preventing theoretical models to compare with multiple data sets efficiently and simultaneously. Therefore, the need of well calibrated, homogeneous and self-consistent observational data sets is of vital importance for all types of theoretical galaxy evolution models, especially for data-driven models like semiempirical ones. The goal of this thesis is to build a holistic perspective among all the aforementioned quantities in galaxy evolution via a semi-empirical approach, exploring the role of each involved physical process. In this thesis, I will present DECODE, the Discrete statistical sEmi-empiriCal mODEl, and its contribution to the field of galaxy evolution. DECODE runs on top of objectby- object dark matter merger trees (hence discrete) generated from (sub)halo mass and infall redshifts distributions (hence statistical), without relying on full N-body simulations. Merger trees are then converted into galaxy assembly histories via abundance matching, using different stellar mass functions as input. First, I will apply DECODE to show the dependence of the output quantities on the input stellar mass function, probing that only specific characteristics of the latter can predict galaxy merger rates and star formation histories self-consistently with the latest observational data sets. Secondly, I will also show how DECODE can also efficiently predict other observables via simple merger models, such as the elliptical abundances, bulge-to-total distributions and intracluster light. Finally, I will present an updated version of DECODE, which grows galaxies via input star formation rate functions along with physically motivated quenching prescriptions, and will show the role of various quenching mechanisms in the stellar mass assembly histories of galaxies

A Content Based Oblivious Watermarking Model

Fu-Hao Ya
Computer network and digitized information, which bring the convenience of spreading and modifying, make it much easier to acquire multimedia data. Therefore, it becomes more and more important to affirm the legal use of multimedia data to protect the intellectual property of the creators. And Digital Watermarking, developed recently, has been proposed as an efficient way to protect copyright.
The principal purpose of this research lies in the development of Oblivious watermarking, which can ensure the existence of watermarking independently without the assistance of original images, and thus can authenticate the authority of copyright. The main method we adopted is to divide the whole image into several equivalent sub-blocks, and to determine if the embedment of the watermark would cause the distortion of the image by analyzing the texture and brightness of each sub-block. Then, each sub-block is given its proper weight, by which we embed the watermark of different energy in it, and, lastly, we amend the edge of the whole image after the embedment of the watermark with a function to retrieve the distortion.
The result of this experiment reveals that the method we took, as mentioned above, is able to effectively defend the attacks which other image processing techniques would cause, such as image cropping (95% cropped), lossy compression (rate of compression=12), image enhancement, multiple watermarks, etc.
