Collecting labeling information of time-to-event analysis is naturally very time consuming, i.e., one has to wait for the occurrence of the event of interest, which may not always be observed for every instance. By taking advantage of censored instances, survival analysis methods internally consider more samples than standard regression methods, which partially alleviates this data insufficiency problem...
OpenFlow has been applied to a variety of demands of the transmission quality of the Internet business and it is still growing on its way. To test this protocol with its evolution consideration, we analyzed the working process of OpenFlow protocol and constructed the CPN model through phasing firstly and then role division for version 1.0. In addition, the selection of tokens and their given values...
The structure design that only by traditional statics calculating procedure for large amusement equipment is not accurate. It must be combined with the kinetic parameters to find the most dangerous working conditions, and then make optimization design for meet safety standards. This paper is studied by taking “self-control plane” amusement equipment cantilever beam as the research object, using the...
In survival analysis, the primary goal is to monitor several entities and model the occurrence of a particular event of interest. In such applications, it is quite often the case that the event of interest may not always be observed during the study period and this gives rise to the problem of censoring which cannot be easily handled in the standard regression approaches. In addition, obtaining sufficient...
More and more researches have demonstrated the benefits of cognitive radio technology in improving flexibility and efficiency of spectrum utilization. In order to encourage primary users (PUs) to share their idle spectrum resources with secondary users (SUs), spectrum trading frameworks are developed. In this paper, the investment problem of spectrum service provider (SSP) is considered which obtains...
There are flow pulsation in all existing piston pump, but this paper suggest a new constant flow method, and a axial piston pump with no flow pulsation in theory is designed. With the simulation in AMESim and MATLAB software, the dynamic characteristics of the new pump include pressure and flow are analyzed.
The paper mainly presents the analytical discussion of MANET and network survivability research that have been done so far. As MANET were open and complex, system hierarchical model was provided, which converted the traditional survivability analysis into hierarchical relation between the key services and the atomic components. This analysis can be applied in quantitative analysis of MANET survivability.
