Research on Crash Safety Design of Electric Vehicle Power Battery
By expounding the collision conditions of electric vehicles, analyzing the characteristics of battery collision under different collision conditions, and studying the traditional collision safety design of electric vehicle power batteries, a new safety design method based on battery damage tolerance is proposed, which aims to provide help for improving the safety protection of electric vehicle power batteries in collision and improve the safety of power batteries in collision, Meet people's requirements for vehicle safety
The moment exponential stability of infinite-dimensional linear stochastic switched systems
This paper studies the 2nd-moment exponential stability of a class of infinite-dimensional linear stochastic switched systems comprising two unstable subsystems. We first construct an algebraic sufficient condition on the existence of multiple Lyapunov functions. Then, two switching strategies are designed to stabilize infinite-dimensional linear stochastic switched systems in terms of the multiple Lyapunov function method. Moreover, the system possesses good robust stability of the switching time with our switching strategies
OpenPARF: An Open-Source Placement and Routing Framework for Large-Scale Heterogeneous FPGAs with Deep Learning Toolkit
This paper proposes OpenPARF, an open-source placement and routing framework
for large-scale FPGA designs. OpenPARF is implemented with the deep learning
toolkit PyTorch and supports massive parallelization on GPU. The framework
proposes a novel asymmetric multi-electrostatic field system to solve FPGA
placement. It considers fine-grained routing resources inside configurable
logic blocks (CLBs) for FPGA routing and supports large-scale irregular routing
resource graphs. Experimental results on ISPD 2016 and ISPD 2017 FPGA contest
benchmarks and industrial benchmarks demonstrate that OpenPARF can achieve
0.4-12.7% improvement in routed wirelength and more than speedup in
placement. We believe that OpenPARF can pave the road for developing FPGA
physical design engines and stimulate further research on related topics
