Abstract Smoking is the main reason for fire disaster and pollution in petrol
station, construction site and warehouse. Existing solutions based on wearable
devices and smoking sensors were costly and hard to obtain evidence of smoking
in unmanned scenarios. With the developments of closed circuit television (CCTV)
system, vision-based methods for object detection, mostly driven by deep learning
techniques, were introduced recently. However, the massive GPU computing
hardware required by the deep learning algorithm made these methods hard to be
deployed. This paper aims at solving the smoking detection problem on edge and
proposes the solution that has fast detection speed,… More >

Abstract User portrait has been a booming concept in big data industry in
recent years which is a direct way to restore users’ information. When it talks
about user portrait, it will be connected with precise marketing and operating.
However, there are more ways which can reflect the good use of user portrait.
Commercial use is the most acceptable use but it also can be used in different
industries widely. The goal of this paper is forecasting gender by user portrait
and making it useful in transportation safety. It can extract the information from
people who violated traffic principle to know… More >

Abstract The heating technological requirement of the conventional PID
control is difficult to guarantee which based on the precise mathematical model,
because the heating furnace for heating treatment with the big inertia, the pure
time delay and nonlinear time-varying. Proposed one kind optimized variable
method of PID controller based on the genetic algorithm with improved BP
network that better realized the completely automatic intelligent control of the
entire thermal process than the classics critical purporting (Z-N) method. A
heating furnace for the object was simulated with MATLAB, simulation results
show that the control system has the quicker response characteristic, the better… More >

Abstract A good hybrid vehicle control strategy cannot only meet the power
requirements of the vehicle, but also effectively save fuel and reduce emissions.
In this paper, the construction of model predictive control in hybrid electric
vehicle is proposed. The solving process and the use of reference trajectory are
discussed for the application of MPC based on dynamic programming algorithm.
The simulation of hybrid electric vehicle is carried out under a specific working
condition. The simulation results show that the control strategy can effectively
reduce fuel consumption when the torque of engine and motor is reasonably
distributed, and the effectiveness of… More >
