Based on an IMU motion sensitive device, a dynamic time warping (DTW) to detect risky activities of people under healthcare has been devised and implemented. DTW, beneficial by matching time sequences with nonlinear dynamic alignment of the sample points to optimize the similarity, is especially a candidate for such a kind of activity detection because that the discrete activity signal sequence would...
To achieve an online robotic path planning system which can dynamically react to environmental changes, the study proposes a real-time system which updates locally the input information and re-plans in time an alternative path for consecutive following under restrained computing capability of the agent. The system consists of a framework of functions to switch the working space successively into so-called...
At present, countries around the world attach great importance to college students' employment. The employment of university graduates has also been a focus of social attention. Playing the advantages of university students hunting for a job on the Internet, on constructing and developing online self-employment service and employment information service and improving the employment information degree...
Deadline assignment is to assign each subtask composing a distributed task with a local deadline such that the global deadline can be met. Today's real-time systems often need to handle hundreds or even thousands of concurrent customer (or service) requests. Therefore, deadline assignment is becoming an increasingly challenging issue with a large number of parallel and distributed subtasks. However,...
Now botnets have become the great threat of Internet Security. To be well prepared for future attacks, it is not enough to study how to defend against the botnets that have appeared in the past. More importantly, we should study advanced botnet designs that could be developed in the near future. In this paper, we present the improved design of an advanced hybrid P2P routing algorithm. The first method...
