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.

一帶一路倡議是中國最近的經濟發展策略，其目的是透過基礎設施發展和貿易，將中國與歐亞大陸的其他國家連結在一起。儘管並非單純為了能源所規劃的策略，但是倡議的組成部分對中國提供日增的能源需求扮演了一個角色。 本論文透過與1990 年代末中國走出去策略之比較，在中國能源需求的大架構下，檢驗一帶一路倡議。為評估一帶一路倡議對中國能源安全的影響，本論文首先界定中國對能源安全的見解，然後分析一帶一路計畫如何應對中國對能源安全的關切。 本論文發現一帶一路倡議可視為走出去策略的後續策略。此外，本論文也發現中國主要是透過供應的角度來觀察能源的安全，且一帶一路計畫（如，石油和天然氣管道的構築）確保了能源運輸的可靠性。 / The Belt and Road Initiative is China’s latest economic development strategy, which seeks to connect China to the rest of Eurasia through infrastructure development and trade. While not a dedicated energy strategy, components of the initiative will play a role in meeting China’s growing energy needs. This paper examines the Belt and Road Initiative in the greater context of China’s energy policy by comparing it to China’s “going-out” strategy of the late 1990s. It assesses the impact that Belt and Road projects will have on China’s energy security by first defining how China views its energy security and then analyzing how Belt and Road projects address China’s energy security concerns. This paper finds that the Belt and Road Initiative can be considered a successor to the“going-out” strategy. It also finds that China views energy security primarily through the lens of supply, and that Belt and Road projects such as port and pipeline construction contribute by ensuring reliability of transport.

Master of Science / Department of Electrical and Computer Engineering / Steven Warren / Networks of low-power, in-suit, wired and wireless health sensors offer the potential to track and predict the health of astronauts engaged in extra-vehicular and in-station activities in zero- or reduced- gravity environments. Fundamental research questions exist regarding (a) types and form factors of biomedical sensors best suited for these applications, (b) optimal ways to render wired/wireless on-body networks with the objective to draw little-to-no power, and (c) means to address the wireless transmission challenges offered by a spacesuit constructed from layers of aluminized mylar. This thesis addresses elements of these research questions through the implementation of a collection of ZigBee-based wireless health monitoring devices that can potentially be integrated into a spacesuit, thereby providing continuous information regarding astronaut fatigue and state of health. Wearable biomedical devices investigated for this effort include electrocardiographs, electromyographs, pulse oximeters, inductive plethysmographs, and accelerometers/gyrometers. These ZigBee-enabled sensors will form the nodes of an in-suit ZigBee Pro network that will be used to (1) establish throughput requirements for a functional in-suit network and (2) serve as a performance baseline for future devices that employ ultra-low-power field-programmable gate arrays and micro-transceivers. Sensor devices will upload data to a ZigBee network coordinator that has the form of a pluggable USB connector. Data are currently visualized using MATLAB and LabVIEW.

International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Boeing Commercial Airplanes has used many methods in the past to measure the structural loads on the wings of its airplanes. The most recent approach is to use arrays of MEMS pressure sensors on the top and bottom surfaces of the wings. By knowing the difference in pressure between the top and bottom of the wings the structural loads on the wings can be calculated. It was decided that in order to build an array of 1100 sensors it would be necessary to condition the sensors and convert the analog output to a digital form at the site of the pressure measurement. This process was taken one step further by converting the output of the A/D converter into engineering units within the sensor module as well. The array is built using a flex circuit card in one foot sections that can be interconnected to form an array of up to 125 sensors. There is a sensor location every two inches on the flex circuit but not all locations are populated. This paper will describe not only the pressure belt but the lessons learned during the development and the implications that these lessons have for smart transducers in general.

Thesis (MSc)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: The ~2.67 Ga Matok pluton comprises calc‐alkaline pyroxene (px)‐bearing and px‐free granitoids. The pluton was constructed by means of two episodes of intrusion each of which had co‐magmatic px‐bearing and px‐free granitoid groups. All the granitoid groups (px‐bearing and px‐free) are characterised by non‐porphyritic and porphyritic varieties. The phenocrysts in both episodes of intrusion are plagioclase ± alkali feldspar and are aligned parallel to the trend of the Limpopo Belt, attesting to a syntectonic emplacement. The time gap between the first and second intrusion is insignificant and magma was most likely stored in the chamber after the first intrusion. Petrography and geochemical signature of both px‐bearing and px‐free granitoid samples have been studied and a petrogenetic model which accounts for the coeval px‐bearing and px‐free granitoids is proposed. The relevance of the syntectonic emplacement of the Matok pluton ie n the Limpopo Belt is also addrssed. Px‐bearing granitoids always have clinopyroxene but orthopyroxene is not always present. Magnetite and ilmenite are present in both px‐bearing and px‐free granitoids but are more abundant in the px‐bearing granitoids and subordinate in the px‐free granitoids. Plagioclase in both px‐bearing and px‐free granitoids is of oligoclase (An12‐30) composition but is relatively more calcic and increases in modal abundance in the px‐bearing granitoids. Alkali feldspar is more dominant in the px‐free granitoids. Hornblende is present in all the px‐bearing granitoids and the px‐free granitoids with ≤71 wt.% SiO2 but is absent in the px‐free granites with >71 wt.% SiO2. Both magmatic epidote and titanite occur exclusively in the px‐free granitoids with ≤71 wt.% SiO2 and are absent in all the px‐bearing granitoids as well as the px‐free gra nites with >71 wt.% SiO2. Px‐bearing granitoids are mainly of dioritic and granodioritic and have subordinate granitic composition while px‐free granitoids are mainly of granitic and granodioritic and have subordinate dioritic composition. All the rocks define well correlated variation of SiO2 with the rest of the major elements. However, there is always a hiatus between the granites with >71 wt.% SiO2 and all other rocks. Px‐bearing and px‐free granitoids at the same SiO2 concentrations tend to have approximately equal concentrations of MgO, CaO and TiO2, whereas K2O concentration is distinctively higher for the px‐free granitoids. The distribution of the high field strength elements (HFSE; Nb, Ta, Zr and Hf) and rare earth elements (REE) is similar in both px‐bearing and px‐free granitoids. On contrary, Th, U, Cs and Rb are characteristically higher in the px‐free granitoids. All granitoids are characterised by negative anomalies of the HFSE (Nb, Ta and Ti) and the LILE (Th, U and Sr) on primitive mantle normalised diagrams. On the one hand, concentrations of compatible elements (Cr, Ni and Mg) in the Matok pluton granitoids are rather low for a mantle source. On the other hand, all the granitoids have superchondtritic Nb/Ta ratios that overlap with those of the Ventersdorp continental flood basalts which extruded in the Kaapvaal Craton at ~2.7 Ga. The continental crust typically has subchondritic Nb/Ta ratio, and superchondtritic Nb/Ta ratios are widely accepted to resemble a mantle source. The implication is that the Matok pluton granitoids had inherited the superchondtritic Nb/Ta ratio from their source; juvenile underplated mafic magmas that had ponded owing to the impact of the Ventersdorp mantle plume. The large volumes of ponded magma s probably induced the high grade metamorphism in the Limpopo Belt. All the granitoids of the Matok pluton are probably products of one partial melting event. One possible way to account for the co‐existence of px‐bearing and px‐free granitoids in the Matok pluton is by means of, at least, two magma chambers; one which was filled with anhydrous magma and the other which was filled with hydrous magma. An alternative model would be that in which there was only one chamber. In the one chamber scenario, the magma was hydrodynamically sorted into zones that differed mostly in fH2O and concentrations of highly fluid‐mobile elements but conserved the uniformity in fluid immobile elements. Regardless of the number of chambers, magma batches intruded in the form of feeder dikes which minimally interacted, thus avoiding the hydration of pyroxene in the px‐bearing granitoids. / SELELEKELA: Plutone ya Matok e fumanehang profinsing ya Limpopo sebakeng seo ho digeologist se tsebahalang ka hore ke Lebanta la Limpopo e ile ya aheya dilemong tse 2.67 biliyone tse fetileng.

Transverse zones are important syn-kinematic components of thrust belt development. Various scales of data were utilized to develop three-dimensional geometric and kinematic models for the Bessemer transverse zone (BTZ) of the Alabama Alleghanian thrust belt. Regional analysis of the BTZ began with the examination of geologic maps (1:250,000, 1:48,000, and 1:24,000 scales), seismic reflection profiles, well data, and previous stratigraphic research. All Paleozoic-age stratigraphic contacts, major thrust faults and associated folds, and various unnamed minor structures were compiled to create two strike-perpendicular, and five-strike parallel, cross sections transecting the extent of the BTZ at a scale of 1:100,000. The balanced and viable cross sections were used to create palinspastic maps of the BTZ. The deformed cross sections and geologic maps, and the restored cross sections and palinspastic maps, model the post- and prekinematic geometry of the transverse zone, respectively. Additional geological fieldwork in the northwestern part of the BTZ permitted the construction of geologic maps (1:24,000 scale) documenting cross-strike links (the fundamental unit of transverse zones) exposed at the present erosional surface (Concord and McCalla 7.5 quadrangles). Balanced and viable geologic cross sections (1:24,000 scale) were constructed from these data and placed parallel and perpendicular to strike of cross-strike links. The cross sections were restored and used to create 1:24,000-scale palinspastic maps of the cross-strike links in this part of the BTZ. The cross sections and maps model the three-dimensional geometry of the cross-strike links comprising the BTZ. Sub-allochthon basement structures are present beneath the thrust transport vectors of cross-strike links in the BTZ, indicating genetic relationships between transverse zone structures and underlying basment structures. Basement-graben related changes in the stratigraphic thickness of the decollement-host horizon are interpreted as having localized and facilitated growth of the Bessemer mushwad, a ductile duplex in the allochthon. The muswad localized the structural position of two thrust sheets and several cross-strike links in the BTZ. Geologic map patterns of the transverse zone indicate a break-back deformation sequence for the BTZ, interpreted as a response to decollement propagation through an allochthon-spanning weak decollement-host horizon, which had large stratigraphic thickness variations in basement grabens.
