Description
East Asia in the aftermath of the Cold War might provide the most favorable case for realist theory due to historical rivalries, territorial disputes, economic competition, great power politics and deep-rooted realist beliefs among politicians in the region. Yet the fundamental realist prediction of balance of power in the region has not materialized. Neither internal nor external balancing in their original senses is explicitly present. This poses a serious challenge to realism and more broadly, western international relations theories for understanding regional dynamics. Several explanations have been put forward in previous research, such as a total rejection of the applicability of realism for explaining East Asian politics, modifying realism by adding new variables, and focusing on domestic variables. Using a neoclassical realist term, underbalancing, this dissertation goes beyond neoclassical realist theory of underbalancing by reintroducing the distinction between external and internal balancing, which has direct implications for the resources needed for a balancing policy and external reactions to balancing policy. In particular, this approach emphasizes the effect of interaction between states on underbalancing. By doing so, it also highlights what is omitted by realism, namely, the agency of the targeted state at risk of being balanced. In other words, the policy of the state that is aware of its risk of being balanced could draw upon foreign policy tools it possesses to neutralize the balancing efforts from others. This notion of state policies influencing the outcome of balance of power is tested with post-Cold War East Asian politics. The cases included China-Japan and China-ASEAN strategic interactions after the Cold War. Based on materials from public media outlets, official documents and recently leaked U.S. diplomatic cables, this dissertation argues that China's policies towards neighboring states- policies expressed variously through cultural, diplomatic, economic and security initiatives- are indispensable to explain the fact of underbalancing in the region.

Description
In nearly all commercially successful internal combustion engine applications, the slider crank mechanism is used to convert the reciprocating motion of the piston into rotary motion. The hypocycloid mechanism, wherein the crankshaft is replaced with a novel gearing arrangement, is a viable alternative to the slider crank mechanism. The geared hypocycloid mechanism allows for linear motion of the connecting rod and provides a method for perfect balance with any number of cylinders including single cylinder applications. A variety of hypocycloid engine designs and research efforts have been undertaken and produced successful running prototypes. Wiseman Technologies, Inc provided one of these prototypes to this research effort. This two-cycle 30cc half crank hypocycloid engine has shown promise in several performance categories including balance and efficiency. To further investigate its potential a more thorough and scientific analysis was necessary and completed in this research effort. The major objective of the research effort was to critically evaluate and optimize the Wiseman prototype for maximum performance in balance, efficiency, and power output. A nearly identical slider crank engine was used extensively to establish baseline performance data and make comparisons. Specialized equipment and methods were designed and built to collect experimental data on both engines. Simulation and mathematical models validated by experimental data collection were used to better quantify performance improvements. Modifications to the Wiseman prototype engine improved balance by 20 to 50% (depending on direction) and increased peak power output by 24%.
