Antioverload high-range accelerometer is playing an increasingly important role in the field of hard target penetration testing, and demand higher accuracy range accelerometers growing consequently. Therefore, a novel with new structure membrane island proposed this article, while measurement significantly improved to 200 000 g. The design mainly based on finite-element method. In general, membrane-island structured piezoresistive formed four-clamped that carries piezoresistor at four ends....
This paper mainly studies the model design of a thin-film heat-flux sensor (TFHFS), and focuses on comparison three dynamic calibration methods. The primary motivation for studying this came from urgent need measurements in extreme environments, one-sidedness performance evaluation corresponding TFHFS. theoretical TFHFS was originally established principle temperature gradient basis thermal radiation boundary. Then, novel developed, which can be used at temperatures above 880 °C has high...
A cobalt(<sc>ii</sc>) chain based on pymca generated <italic>in situ</italic> from the hydrolysis of 2-cyanopyrimidine. The magnetic properties indicate that complex <bold>1</bold> shows single-chain magnet (SCM) behavior with energy barrier 31.2 K.
In this paper, we propose a susceptible‐infected‐susceptible (SIS) epidemic model with demographics on heterogeneous metapopulation networks. We analytically derive the basic reproduction number, which determines not only existence of endemic equilibrium but also global dynamics model. The always has disease‐free equilibrium, is globally asymptotically stable when number less than unity and otherwise unstable. provide sufficient conditions stability unique equilibrium. Numerical simulations...
This paper considers an M-member "individual-based" continuous time swarm model with individuals moving a nutrient profile (or attractant/repellent) in n- dimensional space. It is proved that the members aggregate and eventually form cohesive cluster of finite size for Gaussian Profiles. Moreover, all will converge to more favorable areas under certain conditions.
In this paper, the process of infectious diseases among cities is studied in metapopulation networks. Based on heterogeneous diffusion rate, epidemic model networks established. The factors affecting rate are discussed, and relationship connectivity heterogeneity parameter traffic flow obtained. existence stability disease-free equilibrium endemic analyzed, threshold also It shown that more developed city, greater which resulting large number infected individuals; stronger flow, disease...
In this paper, three dimensional energy supply and demand system with time delay has been considered. We analyze stability properties of the equilibrium points obtain sufficient condition producing hopf bifurcation. By using center manifold theory normal form method, we have explicit formulae which result in Numerical simulations illustrate effectiveness our results. Finally, linear feedback control designed to make asymptotically stable for points.
This paper considers a swarm model with an attraction-repulsion function involving variable communication time lags and attractant/repellent. It is proved that for quadratic attractant/repellent profiles the members of delays will aggregate form cohesive cluster finite size in time. Moreover, all converge to more favorable areas under certain conditions presence delays.
