In order to estimate the forces transmitted onto the cabin in a running vehicle, we need to have proper dynamic models for the vibration isolation components such as rubber bushings. Typically the conventional Voigt model is used in commercial programs. However, this model has limitations in reflection of the frequency dependent characteristics of the vibration isolation components. In this pap...

In this article, the dynamic thermal rating assessment method of oil-immersed power transformer with multiple operating conditions is proposed, considering constraints hot spot temperature (HST), top oil temperature, losses life and maximum allowable current on-load tap changer (OLTC) or bushing, which can determine load curves under different give most sensitive to limit capacity. To improve a...

Abstract: This paper presents an in-wheel vibration absorber for in-wheel-motor electric vehicles (IWM EVs), and a corresponding control strategy to improve vehicle ride comfort. The proposed in-wheel vibration absorber, designed for suppressing the motor vibrations, is composed of a spring, an annular rubber bushing, and a controllable damper. The parameters of the in-wheel spring and rubber b...

To evaluate the sensitivity and specificity of Community Health Survey (CHS), we analyzed data from 11,217 participants aged ≥ 19 yr, in 13 cities and counties in 2008. Three healthcare utilization indices (admission, outpatient visits, dental visits) as comparative variables and the insurance benefit claim data of the Health Insurance Review & Assessment Service as the gold-standard were used....

The problem of automatic fault diagnosis has been an ongoing research in power system. This paper proposes a design of a multi-agent system for bushing condition monitoring system. The agents collect dissolved gases measurements from gas chromatography, analyze the measurements and perform fault diagnosis. The interpretation agents are encapsulated with artificial neural networks so as to enabl...

The Effect of Sanctions on the Job Finding Rate: Evidence from Denmark This paper investigates the effect of sanctions of unemployment insurance benefits on the exit rate from unemployment for a sample of Danish unemployed. According to the findings are that even moderate sanctions have rather large effects. For both males and females the exit rate increases by more than 50% following impositio...

Our paper provides an explanation why cost-of-living adjustment (COLA) provisions and their characteristics vary widely across U.S. industries. We develop models of optimal risk sharing between a firm and union to investigate the determinants of a number of contract characteristics. These include the presence and degree of wage indexing, the magnitude of deferred noncontingent wage increases, c...
