This paper studies an uncertain time-dependent vehicle routing problem with soft time windows. A novel mathematical model which considers both transportation costs (total traveling distance and number of vehicles) and service costs (early and late arrivals) is developed, and the equations for calculating the expected total service costs are deduced under uncertainty and time-dependency. A variation...
This paper proposed a calibration model of pressure sensor based on Support Vector Machine (SVM). In practice, the output of the temperature and voltage pressure sensor is nonlinear and easy to be affected by temperature and voltage fluctuation over a wide measuring range. This model used the support vector machine can approach any nonlinear function ability. It established a calibration model with...
Glaucoma is a common clinical eye disease which has a high incidence all over the world, and it is serious and irreversible damage to the retina and optic nerve tissue, so early diagnosis has a great significance. Based on the characteristics of this disease, we apply the Mumford-Shah image segmentation, and reconstruction of the model to noise (HMSMV), and smooth spline integration technique, is...
China is the largest country to produce and consume Chinese medicine in world. People have come to realize that the side effects of chemical medicine gradually because serious pollution, ecological environment deterioration and human ‘lifestyle disease’ are among the most severe challenges with which human beings are faced today. The voice for “return to nature” becomes louder and louder. To find...
This paper intends to do some research into Index System of Comprehensive Evaluation on hospital management and the weight setting, the influence of politics and economics on modern hospital management, by using the knowledge of System Science and Advanced Mathematics. In this paper, discussed Comprehensive Performance Measurement of hospital management, and according to the basic principles and methods...
Suaeda salsa is a typical pioneer species which can grow well in high salt environmental conditions. The objective of this study is to evaluate the effect of different levels of salinity (5.25, 10.5 and 21g NaCl per kg soil) and nutrient supply (0, 0.3, 0.6 and 1.2g urea per kg soil) on plant morphology, biomass, accumulation of ions and C/N ratio in leaves of S. salsa. The results showed that the...
PCE is an emerging technology to aggregate path computation tasks in some certain elements. The location of these elements may influence network performance. In this paper, an ILP model for PCEs location problem is formulated and a heuristic algorithm is proposed. Simulations are conducted to evaluate the effectiveness of the algorithm presented.
MPLS Transport Profile (MPLS-TP) technology is gaining importance as it becomes a dominant solution for a converged transport network in recent years. MPLS-TP ring protection mechanism defined in standards provides the ability to restore traffic delivery following failure or degradation of network resources to meet carrier-class transport network requirements. The article outlines MPLS-TP ring protection...
By analyzing the data obtained by GPS in dynamic deformation, processing analog GPS data mixed with random interference in the experiments through adopting various wavelet functions and different rank of the wavelet, and contrasting their analysis results, the suitable Daubechies function with the 'N' of six (db6) could be found. And it was used to filter GPS data of dynamic deformation, distill deformation...
The Quad Flat No Lead or QFN package, a near CSP lead frame, is a promising choice for portable wireless applications such as BluetoothTM and RF SoC. Excellent attributes of this advanced package include miniaturized footprint, good electrical performance and excellent thermal characteristics. In this paper, the parasitic parameters of one signal path for a typical 32 I/O (0.5 mm pitch) QFN package...
At present, spatial data has been widely used in many fields, such as GIS.Nevertheless, with the explosion of spatial data and burst from user application demands, lacking of scalability and the trend of being bottle neck have been faded up from traditional centralized GIS. The range query for spatial data is the one of the typical applications. This paper presents a method of range query based on...
Spatial data is generally managed by multiple organizations, and there are significant heterogeneities in these spatial data management nodes within each organization. In order to share spatial data over multiple organizations efficiently, we propose a comprehensive framework of federated spatial data grid based on super-peer network model. Concerning the high overlap of the bounding boxes in the...
Concerning the high overlap of the bounding boxes in the directory of index information about spatial data, a method called Peer X-tree based on X-tree for spatial queries in peer-to-peer systems was proposed. A hierarchical architecture is designed which could be adjusted according to the state of nodes, so Peer X-tree can exploits the resource heterogeneity that inherent in existing peer-to-peer...
