The paper studies the rapid identification technology of short circuit fault and the predictive technology of the time at which the fault current is zero, introduces the current signal can be used for processing cycle of the half-wave Fourier algorithm, improves the algorithm according to the features of short circuit current and the inherent defects of half-wave Fourier algorithm and verifies the...
Forward logistics and reverse logistics collaborative distribution is a powerful way to reduce carbon emission because the vehicle loading efficiency can be improved. Firstly, this paper study the theoretically and proposes a forward and reverse logistics collaborative delivery model. Secondly, Design optimize the target is based on distribution distance, actual load and fuel consumption which are...
Time series clustering is an important task in time series data mining. Compared to traditional clustering problems, time series clustering poses additional difficulties. The unique structure of time series makes many traditional clustering methods unable to apply directly. This paper presents a novel feature-based approach to time series clustering, which first converts the raw time series data into...
Considering the high packet losses and low, varying bandwidth of GPRS/EDGE network and limited computation power of handheld devices, we present and implement a novel SVC video-on-demand system for hand-held devices over GPRS/EDGE network. For the purpose of handling varying bitrate, we propose a priority based layer switching (PLS) adaptation scheme for SVC stream, which not only performs online...
