In this dissertation, I considered five representative images of childhood that the Fifth Generation filmmakers created throughout a thirty-five year period of post-Maoist social transition in China since the beginning of the market reform and opening policy in 1978. To look at evolving childhood through their films is to position the construction of childhood under the prism of the most prominent and controversial cinematic transformation. On the one hand, the Fifth Generation’s shift towards incorporated production, theatrical narration, sentimental style, and generally conservative ideology, signals and constitutes their transition into the paradoxes of “market-socialism;” on the other hand, it maps out the fluctuation and signification of three discourses of capitalism, socialism and Confucianism through evolving images of the child and childhood. I expect this original work that bridges Chinese film studies with childhood studies to unfold a thorough and dynamic scroll, through which I can tap into China’s social transition toward authoritarian neoliberalism, and reveal the discursive mechanism where propaganda of communist regime and re-mobilized Confucian values negotiate and compete with global capitalist orders over the construction of childhood. This dissertation claims that the significance of childhood lies in its capability to fight against a homogenized and hostile environment as both a fundamental humanist domain, and a political, critical and imaginative weapon in commercialized Chinese society.

While the whole world is talking about China’s rise in wealth and power, most focus has been placed on understanding China’s present policies and future orientations. However, very little attention is devoted to examining how historical consciousness affects present China. People take for granted that the past—particularly the landmark traumas of the communist decades—is a far-reaching historical discontinuity, and that China’s profound changes in every aspect of society have rendered the past increasingly irrelevant. However, this thesis argues that this assumption is wrong. This thesis explores the ways that Chinese filmmakers rearticulate the historical traumas which continue to affect Chinese society in the post-WTO era. I will identify three historical traumas that feature prominently in the interplay between past and present. The first, revolution and modernization, occupies a hegemonic status in socialist history. The second historical trauma is the tradition and modernization entrenched in Chinese modern historiography. The third is the 1980s and post-1989 modernization that has found a voice in the period of reform and opening-up. I refer to and analyze a selection of films made by Chinese Fifth Generation filmmakers in the new century—Coming Home (Guilai, dir. Zhang Yimou, 2014), Together (He ni zai yiqi, dir. Chen Kaige, 2002), and The Founding of a Republic (Jianguo daye, dir. Han Sanping and Huang Jianxin, 2009)—to understand these historical traumas. To situate traumatic history in a broader Asian context, I will also offer comparative study of memory of World War II in postwar Japan by undertaking a close reading of Merry Christmas, Mr. Lawrence (Senjo no merii kurisumasu, dir. Nagisa Oshima, 1983). Employing a combination of methods, including textual analysis of films and institutional analysis of film industries, I will demonstrate that cinema finds innovative ways to engage the significant parts of national history and to generate remembrance and interpretation. Rather than reducing the Fifth Generation’s filmmaking trends in the new millennium to simplified government-appeasing or commercialization, this thesis emphasizes an understanding of their recollection of history, memory and trauma in a broader sociopolitical, economic, and cultural context. It shows how various factors—including the government’s cultural policy, economic transformation, and individual and generational sentiments—have influenced and shaped the historical discourses at specific historical moments. While affirming the significant role these films have played in keeping collective memories alive in the public sphere, this thesis also calls attention to their limitations, such as the problematic nostalgia for the Cultural Revolution, as well as the escapist imagination of cultural heritage and traditional values. / Graduate

In this thesis, components and parameters based power models (PMs) are produced to measure the power consumption (PC) of cloud radio access network (CRAN) architecture. In components PM, the power figure of each component within C-RAN is evaluated. After, this model is parametrised such that the computation complexity of each component is converted to a straightforward, but accurate method, called parameterised PM. This model compares cooling and total PC of traditional LTE architecture with C-RAN. This comparison considered different parameters such as, utilised bandwidth, number of antenna, base band units (BBUs) and remote radio heads (RRHs). This model draws about 33% reduction in power. Next, this PC model is updated to serve and exhibit the cost of integrating software defined networks (SDNs) with C-RAN. Alongside, modelling the power cost of the control plane units in the core network (CN), such as serving gateway (SGW), packet gateway (PGW) and mobility management entity (MME). Although there is power cost, the proposed model shows the directions to mitigate it. Consequently, a simplified PM is proposed for virtualisation based C-RAN. In this model, the power cost of server virtualisation by hosting several virtual machines (VMs) is shown, in a time and cost effective way. The total reduction in the PC was about 75%, due to short-cutting the number of active servers in the network. Alongside, the latency cost due to such technique is modelled. Finally, to enable efficient virtualisation technology, live migrating the VMs amongst the servers is vital. However, this advantageous situation is concurrent with VM's migration time and power cost. Therefore, a model is proposed to calculate the power cost of VM's live migration, and shows the effect of such decision upon the total PC of the network/C-RAN. The proposed work converts the complexity of other proposed PMs, to a simplified and costless method. Concurrently, the time cost is added to the imposed virtualisation's time cost to formulate the total delay expected prior to these techniques' execution.

Yes / A four-element compact dual-band patch antenna having a common ground plane operating at 28/38 GHz is proposed for millimeter-wave communication systems in this paper. The multiple-input-multiple-output (MIMO) antenna geometry consists of a slotted ellipse enclosed within a hollow circle which is orthogonally rotated with a connected partial ground at the back. The overall size of the four elements MIMO antenna is 2.24λ × 2.24λ (at 27.12 GHz). The prototype of four-element MIMO resonator is designed and printed using Rogers RT Duroid 5880 with εr = 2.2 and loss tangent = 0.0009 and having a thickness of 0.8 mm. It covers dual-band having a fractional bandwidth of 15.7% (27.12–31.34 GHz) and 4.2% (37.21–38.81 GHz) for millimeter-wave applications with a gain of more than 4 dBi at both bands. The proposed antenna analysis in terms of MIMO diversity parameters (Envelope Correlation Coefficient (ECC) and Diversity Gain (DG)) is also carried out. The experimental result in terms of reflection coefficient, radiation pattern, gain and MIMO diversity parameter correlates very well with the simulated ones that show the potential of the proposed design for MIMO applications at millimeter-wave frequencies. / This work is supported by the Moore4Medical Project, funded within ECSEL JU in collaboration with the EU H2020 Framework Programme (H2020/2014-2020) under Grant Agreement H2020-ECSEL-2019-IA-876190, and Fundação para a Ciência e Tecnologia (ECSEL/0006/2019).

Fifth Generation (5G) cellular networks will experience a thousand-fold increase in data traffic with over 100 billion connected devices by 2020. In order to support this skyrocketing traffic demand, smaller base stations (BSs) are deployed to increase capacity. However, more BSs increase energy consumption which contributes to operational expenditure (OPEX) and CO2 emissions. Also, an introduction of a plethora of 5G applications running in the mobile devices cause a significant amount of energy consumption in the mobile devices. This thesis presents a novel framework for energy efficiency in 5G cloud radio access networks (C-RAN) by leveraging cloud computing technology. Energy efficiency is achieved in three ways; (i) at the radio side of H-C-RAN (Heterogeneous C-RAN), a dynamic BS switching off algorithm is proposed to minimise energy consumption while maintaining Quality of Service (QoS), (ii) in the BS cloud, baseband workload consolidation schemes are proposed based on simulated annealing and genetic algorithms to minimise energy consumption in the cloud, where also advanced fuzzy based admission control with pre-emption is implemented to improve QoS and resource utilisation (iii) at the mobile device side, Mobile Edge Computing (MEC) is used where computer intensive tasks from the mobile device are executed in the MEC server in the cloud. The simulation results show that the proposed framework effectively reduced energy consumption by up to 48% within RAN and 57% in the mobile devices, and improved network energy efficiency by a factor of 10, network throughput by a factor of 2.7 and resource utilisation by 54% while maintaining QoS.

一帶一路倡議是中國第五代領導人的政策之一，應該被視為整體戰略的一部分。為了評估一帶一路倡議的實際目的與風險，研究中國地緣政治與社會經濟局勢、前幾代中國領導人的政策（如西部大開發）、現任第五代領導人的政策（如中國夢與四個全面）。雖然並非與其它相關的分析相互排斥，結論指出一帶一路與第五代領導人其它政策具有協同效應、同時面對相對的急迫性，是中國第五代領導人經濟改革、輸出國營企業生產能力過剩、減輕資產泡沫破裂風險的工具之一。 / The Belt and Road Initiative is one corner of the Chinese fifth-generation leadership’s policymaking under the Xi Jinping administration, and should be understood as part of a cohesive whole. This study assesses the BRI, its actual goals, and its risks when analyzed alongside China’s geostrategic and socioeconomic positions, similar policies from previous generations of Chinese leadership such as the Western Development Strategy, and existing concurrent policies from the fifth-generation Chinese leadership such as the Chinese Dream and the Four Comprehensives. While not mutually exclusive with other explanations proposed for the BRI, this study suggests that due to its synergy with existing policies and its exceptional urgency, the fifth-generation leadership primarily uses the BRI as one tool amongst many to accommodate its economic reform, to export the production overcapacity of state-owned enterprises, and to mitigate any risks of an asset bubble collapse.

Internet of Things, or the infrastructure of the information age society, is an expanding area of research. It is the idea that physical things that we have today, can be turned into devices by being connected to a network. The purpose of these devices is through more sensors and actuators, allow smarter and more robust infrastructure to be built, as well as improving consumer devices interoperability. This thesis will investigate the current state of the art application layer communication protocols that have been developed with resource constrained mobile devices in mind. It will look specifically at high latency mid-range wireless cellular communication by investigating how the protocols affect energy consumption for an embedded Internet of Things device. This is done with the constraint that these findings needs to be applicable to the fifth generation of cellular networks, as well as extensions to current generation standards. The application layer communication protocols Constrained Applications Protocol(CoAP), Message Queue Telemetry Transport(MQTT) and Hypertext Transfer Protocol(HTTP) used on multiple modem modules, are investigated in a quantitative approach in deductive survey experiments, testing a variety of what is concluded to be typical sensor and actuator scenarios. The goal with the survey, is to ultimately select the protocol that shows to be the most suitable for a project to build a prototype platform for embedded mobile devices in the shape of publicly shared bikes in a city. This prototype is described and its architecture and design decisions are presented and argued for. The survey discovers that CoAP is the most suitable protocol for the purpose of the thesis, and proceeds to show how it is applied to the described platform.
