Sea surface temperature anomalies in the North Pacific Ocean

Sea surface temperature anomalies in the mid-latitude North Pacific Ocean were compared with a first-order autoregression model in which the anomalies are forced by local atmospheric white noise. The results showed that the model can explain the power spectrum of the anomalies for a little over 50% of the investigated regions, mainly in the central regions of the Pacific, but fails, not surprisingly, in regions of strong oceanographic processes

Traditional Chinese Philosophy in China’s Modern International Relations

Since gaining power in 2002 Hu Jianto and long-time ally Premier Wen Jiabao have been digging deep into the Communist-Chinese canon as well as ancient Confucian, and other traditional philosophical themes and practices to articulate President Hu Jianto’s foreign policy message “the Three Harmonies”. This message of the peaceful rise of China rang hollow in the ears of many politicians and analysts. (Lam 2006) Was Hu Jianto a leader who based his foreign policy on traditional Chinese philosophies such as Confucianism, or is China’s foreign relations ; as Richard Bernstein and Ross Munro put it “driven by nationalist sentiment, a yearning to redeem the humiliations of the past, and the simple urge for international power…” to become the dominant power or a new hegemonic power in Asia?

Political knowledge and voter turnout

This paper examines the relationship between a voter's level of political knowledge and the choice to vote. The issue of voter turnout is one of the major topics in American politics and has been studied extensively. This study seeks to fill a gap in the current body of academic research that fails to account for the significance of political knowledge as a predictor of voter turnout. Since political knowledge is, in part, a product of many other variables (including both socio-demographic and psychological), it serves as a single predictor that can encompass elements of other predictors. Using 2004 NES data, this study shows that an increase in campaign political knowledge is significantly correlated with an increase in the likelihood that the respondent will vote.Department of Political ScienceThesis (M.A.

Improved relay chatter detector

Detector provides go/no-go sensing of momentary relay or contact opening during vibration testing. Device compares duration of unwanted openings to calibrated standard and lights indicator if standard is exceeded. Stability and reliability are higher than in any other comparable device

WHAM Observations of H-Alpha, [S II], and [N II] toward the Orion and Perseus Arms: Probing the Physical Conditions of the Warm Ionized Medium

A large portion of the Galaxy (l = 123 deg to 164 deg, b = -6 deg to -35 deg), which samples regions of the Local (Orion) spiral arm and the more distant Perseus arm, has been mapped with the Wisconsin H-Alpha Mapper (WHAM) in the H-Alpha, [S II] 6716, and [N II] 6583 lines. Several trends noticed in emission-line investigations of diffuse gas in other galaxies are confirmed in the Milky Way and extended to much fainter emission. We find that the [S II]/H-Alpha and [N II]/H-Alpha ratios increase as absolute H-Alpha intensities decrease. For the more distant Perseus arm emission, the increase in these ratios is a strong function of Galactic latitude and thus, of height above the Galactic plane. The [S II]/[N II] ratio is relatively independent of H-Alpha intensity. Scatter in this ratio appears to be physically significant, and maps of it suggest regions with similar ratios are spatially correlated. The Perseus arm [S II]/[N II] ratio is systematically lower than Local emission by 10%-20%. With [S II]/[N II] fairly constant over a large range of H-Alpha intensities, the increase of [S II]/H-Alpha and [N II]/H-Alpha with |z| seems to reflect an increase in temperature. Such an interpretation allows us to estimate the temperature and ionization conditions in our large sample of observations. We find that WIM temperatures range from 6,000 K to 9,000 K with temperature increasing from bright to faint H-Alpha emission (low to high [S II]/H-Alpha and [N II]/H-Alpha) respectively. Changes in [S II]/[N II] appear to reflect changes in the local ionization conditions (e.g. the S+/S++ ratio). We also measure the electron scale height in the Perseus arm to be 1.0+/-0.1 kpc, confirming earlier, less accurate determinations.Comment: 28 pages, 10 figures.

Diffusion bonding of IN 718 to VM 350 grade maraging steel

Diffusion bonding studies have been conducted on IN 718, VM 350 and the dissimilar alloy couple, IN 718 to maraging steel. The experimental processing parameters critical to obtaining consistently good diffusion bonds between IN 718 and VM 350 were determined. Interrelationships between temperature, pressure and surface preparation were explored for short bending intervals under vacuum conditions. Successful joining was achieved for a range of bonding cycle temperatures, pressures and surface preparations. The strength of the weaker parent material was used as a criterion for a successful tensile test of the heat treated bond. Studies of VM-350/VM-350 couples in the as-bonded condition showed a greater yielding and failure outside the bond region
