A polygon approximation based approach is proposed to improve the query efficiency in querying spatial data in digital achieving system. Although the query efficiency can be increased if the number of sides of n-sided polygon decreases, the search precision can be reduced accordingly. Thus, in the proposed approach, the query efficiency and search precision can be well controlled according to the...
Joint clustering of multiple networks has been shown to be more accurate than performing clustering on individual networks separately. Many multi-view and multi-domain network clustering methods have been developed for joint multi-network clustering. These methods typically assume there is a common clustering structure shared by all networks, and different networks can provide complementary information...
In this paper a measurement method for InP-Based HBT devices to 220GHz is presented. S-parameters are de-embedded using TRL calibration structures (70–220GHz) fabricated on-wafer. The results shown in this paper are characterized at 75–110GHz and 140–220GHz. Good agreement between the low and high frequency measurement is achieved demonstrating the capability of TRL calibration in S-parameters extraction...
With the recent popularization of smartphones, more attention has been given to design dynamic keys for smartphone communications. In this paper, we particularly work to meet the requirement of encrypted information sharing among closely located smartphones. Considering the fact that GPS locations of smartphones are available, we propose a key agreement scheme, denoted by LSKA, based on the location...
As vehicles meet each other occasionally in VANETs, users will naturally have the requirement of protecting their privacy during VANET communications. The privacy requirements bring unique challenges for the communication setup and maintenance as any information (such as IP address and MAC address) that may relate to the users' IDs should not be used. To resolve this problem, we propose to utilize...
This paper describes the position and force control of a novel two-finger gripper using force control technology, a master-slave force control strategy is deveoped for making the force track the desired force quickly with lower overshoot. PID controller is adapted to the position system for the master finger, and force control is used to the slave finger with grey GM(1,1) model, the prediction models...
VISA over LAN was used to design remote automatic test system, in which MATLAB was selected as the application development environment to enhance the capability of data processing and analysis. Native GPIB commands and queries were funneled to/from VISA instrument object using Instrument Control Toolbox functions, and then used to control electrical measuring instruments through VISA I/O Library API...
Brassica rapa L. ssp. chinensis (L.) Hanelt is an important vegetable in eastern Asia. Its leaf area is one of main factor of influencing on the yield of individual plant. To reveal the mechanism of the leaf expansion, the joint segregation analysis of multiple generations (P1, P2, F1, B1, B2 and F2) was used to analyze the genetics of leaf expansion trait in combination SW-13×L-118 of Brassica rapa...
In wireless sensor networks (WSNs) deployed in an outdoor environment, obstacles may occur as a result of a non-uniform distribution of the sensor nodes or the presence of barriers. These obstacles result in a degradation of the network performance, so obstacle identification is a major concern in most WSN applications. This paper develops a Decentralized Boundary Detection (DBD) algorithm for identifying...
