Many exist localization algorithms are unbiased estimators. However, the estimation performance presents biased feature in the real location systems. On the other hand, many biased location estimators show advantages that unbiased estimators can not achieve, e.g., robust to the noise, more accurate estimation and low complexity. In this paper, we propose a biased localization estimator and a hybrid...
Consistent hashing-based DHT networks have an inherent load balancing problem. The problem becomes more severe in heterogeneous networks with nonuniform and time-varying popular files. Existing DHT load balancing algorithms are mainly focused on the issues caused by node heterogeneity. To deal with skewed lookups, this paper presents an elastic routing table (ERT) mechanism for query load balancing,...
Our paper presents an explicit infinite-dimensional Luenberger type observer for a class of vibrating systems. Further numerical investigation is undertaken for the observer based on a rotating Euler elastic beam system, including the eigenvalue distribution of the error system and the robustness of the observer. By using the finite element method numerical simulations are carried out to illustrate...
