Genome-wide association studies (GWAS) have been widely applied to identify informative SNPs associated with common and complex diseases. Besides single-SNP analysis, the interaction between SNPs is believed to play an important role in disease risk due to the complex networking of genetic regulations. While many approaches have been proposed for detecting SNP interactions, the relative performance...
In order to prevent any accident from happening, a safety assessment modeling approach combined with analytical hierarchy process (AHP), signed directed graph (SDG) and hazard and operability (HAZOP) is proposed for thermal power plants in this paper. AHP is used to divide the production equipments for thermal power plants into several hierarchies and it can simplify the modeling difficulties by using...
Ray-space interpolation is one of the key technologies to utilize free viewpoint video (FVV). A novel ray-space interpolation method is proposed in the paper. Detection of ray directionality is based on a whole row of pixels to establish the search direction, then adaptive judgment is made as to whether the detection of ray directionality based on pixel by pixel analysis is needed and a reasonable...
J2EE model and technology, and the concept and structure of MVC pattern, are introduced in this paper. Based on the four-tier J2EE architecture and the MVC pattern, a technology roadmap of the e-commerce system architecture is planned out: JSP plus Servlet plus Session Bean plus CMP plus database, which makes up the shortcomings of unclear business logic among tiers in J2EE, simplifies the development...
With the fast development of information technology, the application environment and multimedia services in ad hoc networks, all of these are needed to support QoS. High-efficient and reasonable MAC protocol is the key point to provide QoS support in the network. In this paper, we analyze some typical QoS MAC protocols, and propose an adaptive QoS MAC protocol-AQMP, which is based on IEEE802.11 protocol...
This paper examines fractional-order dynamical model of happiness. The dynamics of this system is studied numerically. The system displays many different dynamic behaviors, such as periodic motions, chaotic motions and divergence. It was found that chaos exists in the fractional-order system with order less than 3. In this study, the lowest order for this system to yield chaos is 2.97. The results...
In this paper, we present a fault-tolerant wormhole routing scheme, called two-level-turn-model scheme, in the tori with revised convex faults. Our routing scheme is based on the turn model, which itself could tolerate some faulty nodes for some messages. Based on the fault-tolerant properties of the turn model, two patterns of the turn model are complementary to tolerate the faults in our solution...
Service level agreement (SLA) is a contract between the service provider (SP) and the customer. Among various parameters, SLA imposes penalties on the SP when the customer's quality-of-service (QoS) requirements are violated. Hence, it is desirable to avoid SLA violations and such penalties. SLA also states the maximum amount of downtime a connection may tolerate during its lifetime. In this study,...
The design for a 0.3 THz 400 W CW gyro-monotron is done and TE06 operating mode is chosen in the paper. The RF cavity mode field distribution and the diffraction Q value is optimized using HFSS software, so the starting current and operating magnetic field is chosen to restrain the mode competition. The simulation results including the peak output power 400 W and the electron efficiency 20% in the...
Most Active Queue Management (AQM) algorithms keep the queue length of the router at a reference value. While when the network traffic is heavy, these algorithms tend to cause high packet loss ratio, large queue oscillations, etc. To address these issues, a new method called Auto-tuning Reference Queue (ARQ) is proposed in this paper, which can be incorporated in any existing AQM algorithms with fixed...
This paper presents a new Web-based optimization method for path generation synthesis of planar four-bar linkage. The technical features of this method are analyzed and a Web-based design mode is confirmed, which is based on browser/server framework and combines the characteristics of optimization theory and of Web techniques. In the web design environment, it can accomplish remote design between...
An online information management system about the special vehicles enterprise is actualized for the enterprise architecture, the generalized business, and the key target of production management, in order to improve the production management level of the enterprise in this research. The system structure through integrated requirements is established for several aspects of the development processes...
In this paper, we would present a fault-tolerant wormhole routing scheme, called two-level-turn-model scheme, in the tori with convex faults. The reason why we choose the convex faults is that the shape of the convex faults is instrumental to design an effective fault-tolerant routing algorithm. Compared with many other solutions, which mainly focus on providing extra virtual channels to tolerate...
A number of previous studies have assessed the performance of torus networks with same bisection bandwidth. In this paper, the performance of torus networks is studied under the assumption of constant node size and constant channel width. We investigate the effect of dimension on the performance of different topologies. Results obtained through simulation experiments confirm the predictions on the...
For a WDM mesh network with shared-path protection, we propose to exploit the holding time of a connection to re(de)fine the customer's availability targets and achieve significant reduction in blocking probability.
We propose a novel restoration scheme by jointly considering accumulated downtime and SLA requirements of faulty connections. Results from simulation experiments demonstrate that the scheme achieves high restoration success rate and improves resource utilization.
We propose a novel scheme for dynamic connection reprovisioning with resource preemption. Study cases show that SLA violations are minimized, particularly for connections with high SLA requirements under heavy network load.
In optical wavelength-division multiplexing (WDM) networks, the progress in new technologies is paving the road towards dynamic optical transport networks in which leasable circuits can be set up and released on a short-term basis while providing huge capacities to bandwidth-hungry applications. Since interruption of a high-speed optical connection means a huge loss of data information, such connections...
In order to overcome the limitation of single sensor in vehicle integrated navigation system, cascade fusion architecture is proposed to enhance the reliability of location information. Our research is focus on the algorithm in decisionmaking level of the fusion architecture, which is used to fuse the information from Global Positioning System (GPS), Kalman filter and Map Matching (MM) to get the...
In this paper, we present a method using phase features for content based image retrieval (CBIR). Two related key issues of CBIR are feature extraction and similarity measure. However, most traditional methods treat them respectively and prevent further performance improvement. The method proposed here is based on the multi-scale local phase feature (MLPF) and local weighted phase correlation which...
