Bending Stresses

Existing methods for estimating the bending stresses of buried pipeline section based on the survey data for the depth of the axis of the pipeline from the ground surface are characterized by a large error between the real values of the bending stress and the values of the bending stress obtained from the calculation results based on the survey data. The purpose of this study is to improve the methodology for calculating the bending stresses of buried pipeline section based on the results of determining the depth of the axis of the pipeline from the ground surface, taking into account the design features of the pipeline and the used search equipment. Mathematical models are proposed that allow for the set value of the maximum error in determining bending stresses for a particular pipeline to choose the optimal measurement step before the survey, which will allow to reduce the error. Explanations are given on the choice of the maximum step of the study based on the strength characteristics of the pipeline. A calculation is provided that confirms the adequacy of the developed mathematical models and the possibility of their application in practice.

Penelitian ini bertujuan untuk mengetahui apakah terdapat kointegrasi antara ekspor dan impor di Indonesia. Metode yang digunakan dalam penelitian ini adalah Uji Kointegrasi Gregory-Hansen dengan pertimbangan adanya structural break berdasarkan pada data tahunan ekspor impor Indonesia dari tahun 1970 sampai dengan 2013. Hasil penelitian memperlihatkan bahwa tidak terjadi kointegrasi antara ekspor dan impor. Hal ini berarti bahwa Indonesia menghadapi masalah neraca pembayaran, serta defisit perdagangan yang terjadi bukan merupakan fenomena jangka pendek. This research aims to investigate empirically the existence of Indonesian export import cointegration. This Research used the Gregory-Hansen cointegration analysis due to structural break based on Indonesia Export import annual data (period of 1970-2013 ). The results showed that there is no-cointegration of Indonesia export and import which means that Indonesia is facing international budget constraint and trade deficit isn’t a short term phenomenon.

Inherent Tendency

In our paper we focus on situations when central banks have to conduct monetary policy in a world in which they cannot rely fully on what is regarded the best practice and they have to cope with financial system inherent tendency to be unstable. Both phenomena are rooted in János Kornai’s intellectual heritage highlighting that economy tends to divert from equilibrium and that soft budget constraint erodes economic actors’ behavior.

The Cost

It is of great importance to identify the location of the harmonic sources for the harmonic governance in the power system. Applied with optimal measurement placement (OMP) and harmonic state estimation (HSE), this paper presents a novel process based on PMU measurements to locate the harmonic sources in the distribution network. Considering the cost and the observability, the OMP can provide a scheme of the measurement placement with the minimum number of PMU measurements. In order to simplify the HSE equation, the measured data are converted to the form of voltage by the method proposed in this paper.By solving the HSE equation, the location and magnitude of the harmonic source are evaluated. The methodology is applied to the IEEE 33-bus system, and the obtained results are properly analyzed.

Escalation is a key characteristic of many consumption behaviors that has not received theoretical attention. This paper aims to propose both a definition and a theoretical treatment of escalation in consumption. We define escalation as a subject’s attempt to obtain “more” or engage in consumption behaviors that are “more intense” on a measurable, quantitative or qualitative, objective or subjective, scale (more difficult ski slopes, stronger drugs, harder sex, better restaurants etc.), even if the subject preferred less intense consumption behaviors in the past. Further, this evolution in behavior also occurs if the budget constraint does not change. We will find endogenous and exogenous theoretical microfoundations for escalation in models of hedonic adaptation, desire for novelty, acquisition of consumption skills, rising aspirations, positional effects, and envy. However, we will also discuss the possibility that the tendency to escalate is a specific innate behavior inherent to human nature. Finally, we will propose a preliminary theoretical formalization of such behavior and indicate the possible implications of taking escalation into adequate consideration.

Abstract Eurobonds, dubbed as Coronabonds in the context of the current coronavirus crisis, are being hotly debated among the euro area member states amid the COVID-19 pandemic. The debate is in many ways a retread of the euro area sovereign debt crisis of 2011–2012. As China’s “debt centralization/decentralization” experience is comparable with the introduction of Eurobonds in the European Union (EU) in terms of institutional mechanism design, we review our previous series of studies of China’s “debt centralization/decentralization” experience to shed some light on the Eurobonds debate. We obtain three key lessons. First, the introduction of Eurobonds in EU is likely to soften the budget constraint of the governments of the euro area member states. Second, it is also likely to strengthen the moral hazard incentives of the governments of the euro area member states to intentionally overstate their budget problems. Finally, the magnitudes of the moral hazard effects generated by the introduction of Eurobonds in EU are likely larger than their respective counterparts in China.
