Authors: Yang Yu Lin , Su Bao Lei
Published: June 2014

In view of the time interleaving of the relevant processes in runway reconstruction project and the simplification of the relevant processes in current schedule optimization models, runway reconstruction project scheduling is treated the same way as the ordinary construction project, which can’t meet the requirement of the efficient use of limited daily construction time. Statistics of the daily supervision management data in an actual runway reconstruction project are analyzed according to each process respectively. The law of data distribution can help to judge the reliability of the planed schedule and some process with actual physical meaning can be divided into several processes having no physical meanings as the process time interleaving taken into consideration. Then a new equivalent schedule network diagram with independent processes is built to replace the old one and the Critical Path Method (CPM) technique can be used to solve this mathematic problem and develop a schedule. The schedule plan from the modified schedule network diagram can prove the validity of the modified optimization model compared with the one from the ordinary schedule plan method.

Published: June 2014

Diabetes is a disease characterized by the inability of the pancreas to regulate blood glucose concentration. The development of the closed-loop control method for the treatment of type 1 diabetes is a highly desired endeavor for patients, physicians and scientists. Focusing on the need for maintaining normal glycaemia, the paper proposes an integrated closed-loop control method, which is the model predictive control (MPC) method combined with model parameters estimation. Using the static glucose model to be the internal model can’t achieve the good performance in different objects because of the individual differences. By updating the internal controller model with current measurement information using the parameters estimation, mismatch between the actual controlled object and the internal controller model is significantly reduced. Therefore, the predictions of future glucose values using the updated model are more accurate than those of the static input–output model. Finally, the integrated control method was tested on the T1DM simulator which was accepted by the FDA. Four objects are selected randomly in T1DM simulator. The control results showed it can modulate the glucose concentration to 85~120 mg/dl without severe hypoglycemia in the effective time. In conclusion, it is promising for the control of glucose concentration in subjects with type 1 diabetes.

Published: June 2014

Researches on surface electromyography (sEMG) for upper-limb prosthesis control have been going on for several years. Most published studies on prosthesis usually use the steady-state sEMG or the transient sEMG for identification. However, the transient sEMG is less stable than steady-state sEMG. The nonstationarity in transient sEMG greatly affects the performance of myoelectric control. In this paper, we propose a method based on sparse representation to capture the characteristics of transient sEMG to identify movements. Experiment results show the proposed method extracts the variations in transient sEMG activity from different movements effectively. The proposed feature achieves a satisfactory classification rate, which outperforms the other features.

In wideband radar situation, target-spread and all scattering points back wave could be considered as the pulse train of random parameters. The wideband radar target and built the related model. Then it gave two methods of target detection, one is Energy Accumulation and the other is the IPTRP. It also presented the simulation result of these two methods performance curves. It showed that the IPTRP improved by more than 3dB in the same SNR.

Published: June 2014

The widespread deployment of smart meters for the modernization of the electricity distribution network has been associated with privacy concerns due to the potentially large number of measurements that reflect the consumers’ behavior. At the same time, how to extract important knowledge from the potentially large of measurements — these measurements are spilt among various parties, has already became a hot topic in the field of data mining. In this paper, we present protocols that can be used to compute meter measurements over defined sets of meters without revealing any additional about the individual meter readings, and address secure mining of association rules. Thus, most of the benefits of the smart grid can be achieved without revealing individual data.
