DESIGN OF A TWO-AXIS MEMS SENSOR FOR MEASURING THE FORCE AND TORQUE WITH COMB STRUCTURE
Published 2018-01-01“…Based on the micro-electro-mechanical systems(MEMS) technology,the chip structure of a two-axis force sensor with comb structure was designed.Silicon force sensitive structure converted the faint mechanical signals into measurable electrical signals.After finite element model was established,the structure and electrical properties of the sensor were analyzed.The corresponding relation between the mechanical signals and the electrical signal was obtained.The mode analysis and harmonic response analysis were performed for the model.The natural frequency of the structure and the harmonic response frequency both are verified that far away from the operating frequency of the system.The work stability and measurement accuracy of the chip are guaranteed.The resolutions of force and moment of the sensor chip are 2.85 μm and 0.0382 μN·m,respectively.The linearity of the signal conversion reached 0.999 6 and 0.999 9.The first and second order modal natural frequency is783.28 Hz and 1 294.3 Hz and harmonic response frequency is 770 Hz.Simulation results meet the requirement of performance specification.…”

Approach of location privacy protection based on order preserving encryption of the grid
Published 2017-07-01“…The centralized structure of the trusted third party is a major privacy protection structure on location based services.However,if the central third party server can not be trusted or compromised,users have the risk of leakage of privacy location.Aiming at the above problems,location privacy protection approach based on a user-defined grid to hide location was proposed.The system first automatically converted the query area into a user-defined grid,and then the approach utilized order preserving encryption,which made the user’s real-time position in the hidden state could still be compared.Because the information in the process of the approach was in a state of encryption,the server could not know the user’s location information,thus improved privacy protection of the user location.The central third party server only need to do simple comparison work,so its processing time overhead would effectively decrease.Security analysis certificate the security of the proposed approach and simulation experimental show the proposed approach can reduce the time cost of the central third party server.…”

Reliability modeling and planning of energy harvesting based on uncertainty theory
Published 2018-05-01“…Energy harvesting network is a new form of computer networks.It can convert the environmental energy into usable electric energy,and supply the electrical energy as a primary or secondary power source to the electronic device for network communication.However,the energy harvesting process has great volatility and uncertainty,the traditional analytical method based on probability distribution function to describe the energy collection process can not accurately simulate the actual situation,resulting in higher depletion probability of nodes,then the reliability cannot be guaranteed as a result.For this,the energy harvesting reliability of energy harvesting nodes was defined,represented with the degree of normal operation,respectively set up the node reliability models with no battery and infinite battery.As an example for maximum node achievable rate,the uncertain multilevel programming model based on node reliability was put forward,then the network efficiency was improved under the premise of ensuring node reliability.An energy average allocation (EAA) algorithm was proposed and the upper bound of competitive ratio of the algorithm was proved theoretically.Finally,the actual wind power data was taken as an example to verify the feasibility and effectiveness of the proposed model and method.…”
