Objectives and makings of monetary policy in Japan
We attempt to identify significant objectives of monetary policy for the period from 1990 to 2013 and compare the results to those obtained by Asako and Kanoh (1997) for an earlier sample period. With the introduction of nontraditional monetary policy management such as zero-interest-rate policy and quantitative-easing policy, we find and examine some important shifts in the role of government bonds modeled by Asako and Kanoh as one of five stabilizing objectives of the monetary policy. We also look into the making of the monetary policy by focusing on the votes by the Bank of Japan Policy Board members

Component HCF Research Based on the Theory of Critical Distance and a Relative Stress Gradient Modification
<div><p>For the critical engine parts such as the crankshaft, the fatigue limit load is one of the most important parameters involved the design and manufacture stage. In previous engineering applications, this parameter has always been obtained by experiment, which is expensive and time-consuming. This paper, based on the theory of critical distance (TCD), first analyzes the stress distribution of a crankshaft under its limit load. In this way, the length of the critical distance can be obtained. Then a certain load is applied to a new crankshaft made of the same material and the effective stress is calculated based on the critical distance above. Finally, the fatigue limit load of the new crankshaft can be obtained by comparing the effective stress and the fatigue limit of the material. Comparison between the prediction and the corresponding experimental data shows that the traditional TCD may result in bigger errors on some occasions, while the modified TCD proposed in this paper can provide a more satisfactory result in terms of the fatigue limit for a quick engineering prediction.</p></div
