Some of the main ranking features of today’s search engines reflect result popularity and are based on ranking models, such as PageRank, implicit feedback aggregation, and more. While such features yield satisfactory results for a wide range of queries, they aggravate the problem of search for ambiguous entities: Searching for a person yields satisfactory(More)

In view of the exploding distribution of digitized audio material, computer-based methods have become indispensable for processing and analyzing the content of music signals. To evaluate analysis results obtained by automated methods, one requires manually generated highquality labeled data and the feedback by music experts. In this paper, we introduce(More)
This paper presents active disturbance rejection control system for toggle-motor coupling servomechanism system. Genetic algorithm and mixed H2/Hinfin norm index are utilized to optimize the system parameters; Monte-Carlo method is applied to evaluate the robustness of the control system. Simulation results show that under the condition of external(More)
This paper establishes a semi-supervised strategy for extracting various types of complex business relationships from textual data by using only a few manually provided company seed pairs that exemplify the target relationship. Additionally, we offer a solution for determining the direction of asymmetric relationships, such as “ownership of”. We improve the(More)
This paper present robust Auto-MAP-Modify method for High-power Variable-Speed Governor of Diesel Engine by extended state observer. Firstly the uncertain between MAP parameter and real parameter is defined as additive-Perturbations. Secondly the original controller is reconstructed as a dynamic controller for sensitivity and noises, meanwhile a static(More)
Objective To investigate the expressions of substance P (SP) and its receptor neurokinin/tachykinin receptor 1 (NK1R) in peripheral blood eosinophils of patients with psoriasis. Methods The levels of SP and NK1R in the peripheral blood of both patients with psoriasis and healthy people were detected by flow cytometry. This method was again used to detect(More)
The common rail pressure has a direct influence on the working stability of Opposed-Piston Two-Stroke (OP2S) diesel engines, especially on performance indexes such as power, economy and emissions. Meanwhile, the rail pressure overshoot phenomenon occurs frequently due to the operating characteristics of OP2S diesel engines, which could lead to serious(More)
