In this paper, we introduce a systematic process of design, simulation and experimental validation of a manipulator based on the honeycomb pneumatic network (HPN) structure. The HPN structure shows potential in achieving balance between flexibility and load bearing capacity, which overcomes the shortcoming of pneumatic networks in strength. To reach the best performance of both features above, we...
The formulas of tortuous channel lightning electromagnetic field are obtained by decomposing the current micro-source dipole and solving Maxwell's equations. The waveforms of lightning electric and magnetic fields in different areas are calculated using the transmission line model and pulse function. Then, the characteristics of lightning electromagnetic field for different channel geometries and...
Aiming at the deficiencies of ant colony clustering algorithms in distance measure, convergence rate, similarity clustering, and other aspects, WALF algorithm is presented as an improvement to the LF algorithm. Using weighted hybrid distance as distance measure, and introducing the adaptive mechanism during the process of clustering, ant colonies can adjust the radius of neighborhoods dynamically...
Molecular dynamics simulations of ZnO nanowires (NWs) <xref ref-type="bibr" rid="ref22">[22]</xref> show that the structural relaxation (SR) leads to the distribution of Young's modulus (Y) different from the assumption of the core–shell (C–S) model. It is thus of interest to validate the C–S model in measuring the equivalent Young's modulus and evaluate the effect...
For scheduling services with different features and Qos constraints, this paper proposes a hybrid scheduling strategy, in which delay-sensitive services are granted preemptive priority and non-delay-sensitive services are granted non-preemptive priority. Theoretical analysis verified that preemptive scheme results in longer waiting length of queue.
By analogy with Halbach permanent magnet (PM) array, a novel ironless trapezoid winding array (TWA) is designed to achieve a primarily single-sided and well sinusoidal magnetic field. After deriving the TWA's current density formula in Fourier series, via the magnetic vector potential we derive the analytical solution of its magnetic field, which is verified by ANSYS finite-element method.
The effective analysis of models needs to utilize the structure reduction of workflow model. Based on the structure reduction methods of workflow nets, a simple and effective decomposition algorithm of free choice subnets for workflow nets was proposed, and the time complexity analysis was presented in the paper. Combining the algorithm proposed with the current structure reduction methods of workflow...
