On Exponential Stabilizability for a Class of Switched Nonlinear Systems with Mixed Time-Varying Delays by Jie Qi, Yuangong Sun

“…We study the exponential stabilizability for a class of switched nonlinear systems with mixed time-varying delays. By using a new technique developed for positive systems, we design the average dwell time switching under which the switched nonlinear system is exponentially stable for any bounded delays. …”

Estimation of Urban Link Travel Time Distribution Using Markov Chains and Bayesian Approaches by Wenwen Qin, Meiping Yun

“…Despite the wide application of Floating Car Data (FCD) in urban link travel time and congestion estimation, the sparsity of observations from a low penetration rate of GPS-equipped floating cars make it difficult to estimate travel time distribution (TTD), especially when the travel times may have multimodal distributions that are associated with the underlying traffic states. …”

Real-Time Analysis of Endogenous Wnt Signalling in 3D Mesenchymal Stromal Cells by Fatima Saleh, Alice Carstairs, S. Leah Etheridge, Paul Genever

“…Interestingly, endogenous Wnt signalling was only active during 3D differentiation whereas 2D cultures showed no EGFP expression throughout an extended differentiation time-course. Furthermore, exogenous Wnt signalling in 3D adipogenic conditions inhibited differentiation compared to unstimulated controls. …”

Service impact analysis and visualization display based on massive real-time monitoring data by Junwen LIU, Shuo CUI, Xiaomeng LI, Zhihong LI, Yang LI

“…With the development of electric power informatization,electric power information systems,interactive data and resource systems are also increasing.The amount of data generated during daily operation,has been a serious challenge to system operation and fault judge.But the traditional way of monitoring is simply to carry out data collection and indifferentiated recording,but no effective information is extracted from the monitoring data,while the means of monitoring can't be intuitive to reflect the system physical layer and business layer topology.Through the collection of electric power information system massive real-time monitoring data,and the collected data for effective extraction,the formation of information was interrelated,the mapping relationship between platform monitoring and upper service was established,thus the visualization of data flow was realized.…”

Stochastic differential equations to model influenza transmission with continuous and discrete-time Markov chains by Kazi Mehedi Mohammad, Md. Kamrujjaman

“…Since the basic reproduction number R0 is not sufficient to predict the outbreak, we apply the discrete-time Markov chain (DTMC), continuous-time Markov chain (CTMC), and Itô stochastic differential equations (SDEs) to calculate the probability of the disease outbreak. …”

Research on QR code logistics privacy based on segmented encryption and time-limited control by Liang LIU, Wenbo GUO, Yuwei YANG, Huaiyu GUO

“…In view of the disadvantages of the existing logistics system in the market in user privacy protection,a privacy protection scheme based on QR code segmentation encryption,hierarchical authorization and time-limited control was proposed.This scheme segments all the recipient information into RSA and Base64 encryption,after integration,it is embedded into the QR code.In the process of logistics transportation and delivery,different levels of QR code decryption permissions are granted to different branches or transfer centers to view the designated content.At the same time,the QR code automatically becomes invalid after the user signs for it,so as to protect the user's privacy.The core idea of the scheme is to minimize the contact group of recipient information and reduce the possibility of user information disclosure.…”

Indoor carrier phase positioning algorithm based on time-varying clock error elimination by Shaoshuai FAN, Zhiqiang RONG, Hui TIAN, Lihua LI, Xiaoqi QIN

“…To solve the problems of low positioning accuracy of traditional positioning algorithm and unsynchronized system clock in indoor wireless environment, a 3D positioning algorithm was proposed based on the fusion of triple-differential carrier phase measurements and time difference of arrival (TDoA) positioning.Considering that the time-varying clock offsets between wireless access points lead to lower positioning accuracy, the measurements from a reference terminal were used to eliminate the influence of time-varying clock offsets.The relative positions were estimated based on triple-differential carrier phase measurements, which were fused with unbiased differential TDoA positioning results to obtain the interim estimated positions.Furthermore, the carrier phase observation equations were linearized by Taylor expansion method, and the high-accuracy positioning was realized by solving the integer ambiguities.Simulation results show that the proposed algorithm eliminates the influence of time-varying clock offsets on positioning performance, and the integer ambiguities are resolved in a short time to achieve high-accuracy positioning.…”
