In this paper, stream weight optimization for multi-modal speech recognition using audio information and visual information is examined. In a conventional multi-stream Hidden Markov Model (HMM) used in multi-modal speech recognition, a constraint in which the summation of audio and visual weight factors should be one is employed. This means balance between transition and observation probabiliti...

As additive manufacturing expands into multi-material, there is a demand for efficient multi-material topology optimization, where one must simultaneously optimize the topology, and the distribution of various materials within the topology. The classic approach to multi-material optimization is to minimize compliance or stress while imposing two sets of constraints: (1) a total volume constrain...

This paper proposes a multi-material topology optimization formulation for thermo-elastic structures considering coupled mechanical and uniform thermal loads. The ordered-SIMP multiple materials interpolation model is introduced, combined with examples structural volume minimization under stress constraints. p-norm function the adjusted coefficient was adopted to measure global maximum stress. ...

UAVs formation is a complex nonlinear system. Although quadrotor has many advantages, its dynamics model nonlinear, coupled, and under driven. For model-based controller design, physical constraints, uncertainties external disturbances significantly deteriorate control performance. Therefore, multi-constraints MPC strategy based on error proposed for the formation. Firstly, 3D established by us...
