Surface-enhanced Raman scatters (SERS) spectroscopy is a novel detection technology which has advantages of fingerprint, high sensitivity, simple pretreatment and strong anti-interference for water and has been widely used for the analysis of organophosphorus pesticide residues. Furthermore, the intelligent species identification and quantitative analysis of organophosphorus pesticides can be achieved...
In this paper, we propose an algorithm that determines the optimal user equipment (UE) and base station (BS) association in heterogeneous cellular network, aiming at minimizing network energy consumption and avoiding frequent pico base station (PBS) mode switching, by taking into account the energy consumption of PBS switching-on/off operation. We first formulate the energy minimization problem into...
Aiming at the problem of constructing huge amounts of projected databases in PrefixSpan algorithm, this paper proposes an Improved PrefixSpan algorithm for Mining Sequential Patterns, called BLSPM algorithm (based on bi-level Sequential Patterns Mining). The algorithm use duplicated projection and certain specific sequential patterns pruning, reduce the scale of projected databases and the runtime...
Based on the Fast Fourier Transform(FFT) of sine signal sampling sequence, this article proposed a self - adaptive frequency estimation method using multi - spectral line information which is near the peak of spectral map. To solve the interpolation direction error of rectangular windows Rife ratio method, combining with triangular method, the new method self-adaptively selects different methods according...
Nowadays, most of the computerized network applications are depending on the ability of the servicing packet switching network to integrate different types of traffic from two main categories, real-time and best-effort classes, and provide different QoS guarantees based on the traffic type. Different methods were applied to provide such guarantees, one of the most efficient method used in packet switching...
