An analysis methodology to determine heavy metal emission based on the whole product process was developed. In this article, the smelting technology and the raw materials components of the secondary copper smelting were introduced to analyse the amount of lead waste the site create per year. The balance of lead element gave the kinds and quantity of the waste including lead element clearly. The dust...
MLAT (Multilateration) in the civil aviation is a typical sensor network which locates the positions of aircrafts by the TDOAs (Time Difference of Arrivals) of signal from the aircraft to the different remote stations. It is important for MLAT to ensure the clock synchronization. On the basis of CHAN algorithm, this paper proposes an improvement based on TDOA adjustment. In this method, a reference...
In this paper, flight faults are generated and visual aircraft instruments are created as well as real-time information communication between simulation flight data and virtual instruments is established. Particularly, dynamical faults generation and its corresponding display system are developed and simulated in detail. Finally, the system is validated for authenticity and reliability by taking the...
An air defense decision-making model based on modern artificial intelligence technology is introduced in this paper. It also solve many difficult problems during model establishing, such as design of neural network structure, network propagation algorithm, fuzzy control algorithm and data reduction algorithm. Simulation experiment with typical battlefield situation data is conducted. First, quantify...
This paper is focused on the development of an effective method to optimization inversion on constitutive model parameters of bird material in the numerical simulation of bird impact on an aircraft windshield. The experiments of bird impact on a plate under the velocity of 170m/s were performed and the displacements as well as the strains of the plate were measured. The Murnaghan Equation of State...
This paper researches structure design of dry powder inhalers on clinical use for improvement, based on the theory of ergonomic from the perspective of efficiency, security and flexibility, puts forward a solution and builds up a control model of the system to verify its feasibility. So the improved dry powder inhaler is efficient and easy to use, meeting with the needs of patients.
