Mathematical formula with two-dimensional structure has rich meanings. However, when input mathematical formula on the computer, we can only use finite characters on the keyboard to input string of one-dimensional characters. So the size and the position of a lot of signs and symbols can't be input directly using the keyboard. In order to achieve fine input and display of mathematical formula, according...
Throughput-optimal scheduling has been widely discussed due to its capability to stabilize single-hop multiuser wireless systems if possible. However, most of the previous discussions focused on the underloaded scenario, i.e., the arrival rate lies inside the achievable rate region. The behavior of throughput-optimal scheduling in overloaded multiuser wireless systems is the focus of this paper. We...
According to the empirical analysis in this paper, there is an optimal concentration degree of production and population for Chinese provinces, whether below or above the optimal value will cause serious loss to economic growth. These provinces, such as Guangdong, Hubei, Sichuan, Liaoning, Heilongjiang should scatter production and population to their medium and small cities, so as to avoid the non-economical...
Photoplethysmogram (PPG) of pulse wave has been proposed for analgesia monitoring recently with most attentions paid to its magnitude and little attention to its morphology. Therefore, effect of nociceptive stimuli on the morphology of PPG was studied using a morphological parameter named area ratio (AR). Fifty patients, ASA I or II, scheduled for laparoscopy surgery under general anaesthesia were...
An example-based approach for facial portrait style learning is proposed. By learning a training set with the same style, this method can generate new portraitures which are similar to this style. To obtain facial features with high quality, there are two key elements in this paper: Using an Inhomogeneous Markov Random Field Model (MRF) and a nonparametric sampling scheme to learn the statistical...
The water resources vulnerability (WRV) is defined as the characteristics that water resources system easily suffers damage from natural factors or human activities, and it is difficult to recover to its former status once this damage happens. The quantitative assessment of the WRV is important for the scientific decision-making for the sustainable water resources exploitation and utilization. In...
