Due to many sub-components, such as HGA, carriage, pivot and VCM, etc., any condition change, such as dimension, young modulus, temperature, will change transfer function frequency and phase.

The measurement-based approach obtains real-world performance data of MICA2 mote communications as power transmission levels are varied.

Some works have been done to apply classification learning like SVM to relevance feedback and obtained successful results. However they did not fully utilize characteristic of example distribution in document retrieval. We propose heuristics to bias document showing according to distribution of examples in document retrieval. This heuristic is executed by selecting examples to show a user in neighbors of positive support vectors, and it improves learning efficiency. We implemented a SVM-based interactive document retrieval system using our proposed heuristic, and compare it with conventional systems like Rocchio-based system and a SVM-based system without the heuristic. We conducted systematic experiments using large data sets including over 500,000 paper articles and confirmed our system outperformed other ones","PeriodicalId":415827,"journal":{"name":"2006 9th International Conference on Control, Automation, Robotics and Vision","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122833483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By applying the concept of fictitious zero-moment point (FZMP), a method to maintain the walking stability of humanoid robot under external disturbance is presented. The support polygon and the rotation edge in the case of losing balance in single and double foot support phase are determined in computerized form. A new control strategy is proposed to maintain stability in different environments. The measures to keep stable walking are the adjustment of the support polygon, the push or pull support of hand with environment and the movement modification of upper robot body. The relative position between the FZMP and the rotation edge represents the strength and direction of losing the stability. The optimization gait of humanoid robot was determined by using genetic algorithms.

First, we present an asynchronous algorithm for updating persistent probabilities and prices to avoid collision using local coordination. By casting this algorithm as a best response in a cooperative game, we characterize its convergence analytically. We further model that each node attempts to maximize a selfish local payoff function. We characterize the Nash equilibrium (NE) of the non-cooperative game and prove the convergence of a best response algorithm to the unique NE. Then we study the energy efficient throughput maximization problem when the wireless nodes are constrained by their battery power.
