The onboard traction transformer is a critical equipment of high-speed trains, its running state directly affects the safety and stability train’s operation. Given complexity condition transformer, this paper proposes diagnosis algorithm based on kernel principal component analysis (KPCA) fuzzy clustering. To fully extract status information aging characteristics insulating oil main insulation ...

conclusions although skin traction had no effect on analgesic consumption, it significantly decreased the pain at the end of the first day. the application of skin traction in patients with intertrochanteric fractures is recommended. results the severity of pain was significantly decreased in skin traction group only at the end of the first day after traction application (2.7 ± 0.8 vs. 3.3 ± 0....

background: traction has been suggested to be an effective treatment for symptoms of neck disorder in patients with no contraindications. however, according to previous researches, the effectiveness of traction is controversial, particularly compared to other conservative treatments. this trial was conducted to evaluate the effect of sustained traction, using an over-the-door home cervical trac...

1 With guided-wave approaches becoming prevalent for structural health monitoring, the need has arisen for more effective models employing these methods using piezoelectric transducers. This paper describes an analytical formulation to couple transducer dynamics with axisymmetric guided-wave excitation models for isotropic plates. The finite-dimensional piezo-actuator dynamics are modeled using...

A routine dose computation around brachytherapy seeds employing the Fast Fourier Transform (FFT) has been demonstrated and likened to dose computations in a similar field based on the TG43 recommendations. In applying the FFT convolution model to dose computation, a dose convolution kernel which takes into consideration the anisotropy of the dose distribution around a brachytherapy source in th...

As a software system evolves, its architecture will drift. System changes are often done without considering their e ects on the system structure. Consequently, the concrete (as-built) architecture becomes convoluted over time making continuing development and maintenance activities increasingly di cult and highly error prone. This problem of architectural drift is especially pronounced in open...
