The results show that the information transmission can be enhanced when a certain amount of noise is presented, i.e., aperiodic stochastic resonance (ASR). Then, the influence of signal amplitude and the ST threshold on ASR is examined, the applicability of the ST in reducing the noise level of random signal transmission and improving the quality of output signal via ASR effect is illustrated. This research is of great interest in the field of digital communications.展开更多

Based on the characteristic having two kinds of signal-detection threshold in ternary TTL circuits, a ternary TTL Schmitt circuit having twice reactions of threshold-jumping is designed. The simulation with PSPICE proves that the designed circuit has ideal function of Schmitt circuits.展开更多

Its trigger levels are determined by two Complementary Metal- Oxide-Semiconductor （CMOS） inverters. Contrast with traditional six transistors Schmitt trigger, its temperature and supply voltage characteristics have been analyzed. These two triggers are applied into relaxation oscillator and the result shows that the proposed one in this paper has better performance over wide temperature range, whose temperature coefficient from 0 to 85℃ is 1/5 of the traditional one.展开更多

However, these differences seem to have taken a back seat since both thinkers have been adopted to legitimate the convictions of imperial liberalism. In contrast, this article will show that Schmitt and Kant have essentially more in common than generally assumed but do precisely argue against just war theory, humanitarian interventions, and a unipolar world. On the other hand, Kant＇s liberal and Schmitt＇s illiberal theory do not apply to the classical paradigms of intemational relations. Instead, Schmitt＇s Political Theology and Kant＇s Political Philosophy will be compared along with the antagonistic logic （and ethics） of political existentialism and a peaceful interdependence between states and nations. Considering the contemporary crisis of world order, it should be even plausible that the two dominating paradigms of future international relations might be formed by Kantian and Schmittian premises. Thus, the aim of this paper is not to match Kant and Schmitt once again with the usual approaches in international relations theory but to stretch its theoretical and conceptual spectrum by extracting the inventive contribution both thinkers made to important topics of IR.展开更多
