Traffic jam has caused serious environmental pollution problem to our daily life nowadays. To make clear the effects of different traffic flow drivers' type influence on traffic carbon-dioxide(i.e. CO2) emission, we first modified the traditional coupled-mapping traffic flow car following model, that the driver's sensitivity factor obeys mathematic statistical probability distribution, and deduced...
An improved forward considering car-following model was proposed to describe the automated vehicle's flow behavior. A theorem was proved as a criterion for judging the stability of homogenous automated vehicles flow. The greater forward considering vehicles' number means more stability. A series of simulations were carried out to verify the new model and analyze the stability of automated flow. From...
Traffic patterns of the lanes accommodating the same movement at signalized intersection are different with each other in most cases, which could decrease the efficiency of signal control. This problem derives from drivers' preferences to specific lane, which is contrary to common control strategy that usually takes the lane traffics as a whole. Lane-based timing technique can solve this problem,...
An analytical large signal model based on semi-empirical formulas is presented for describing the DC characterization of GaAs Pseudomorphic High Electron Mobility Transistor (pHEMT), which included pad capacitances, intrinsic elements and extrinsic elements is in good agreement with the theoretical results obtained by performing device simulation. The accurate temperature rise in the GaAs pHEMT's...
This paper is a study of staff issues at the bank, ICBC China. Due to extra and imbalanced staff, the system was idle most of the time. By using the qualitative approach, M/M/s queuing model and discrete event simulation, the staff was sub-optimized. First, observation of the system was conducted and recorded using the existing operations system used by the bank. Arrival time of customers, service...
This paper perfects the simulation model of mass collaborative product development. A new structure of simulation model was presented, and the model considering the participants' learning effect in this paper, which improve the model's reliability. Structure and modeling steps of the simulation were studied, and the model performance under the two different situation "participants learning effect"and...
Noise is electrical or electromagnetic energy that reduces the quality of a signal. Noise affects digital, analog and all communications systems. This paper introduced a noise analysis method based on Multisim. Multisim creates a noise model of the circuit, using noise models of each resistor and semiconductor device, instead of AC models, and then performs analysis. It calculates the noise contribution...
This paper, bases on the trend and seasonal fluctuation of China's monthly railway freight, uses ARIMA model and Holt-Winters model to forecast. After comparison of forecasting results, a final freight result from January to December of 2010 is generated. After verification, the predict results of ARIMA model and Holt-Winters model, with errors lower than 4%, are preferable to be used of railway freight...
In this paper, the exoskeleton robot is first briefly introduced, the mathematical model for the upper limb exoskeleton robot and the force and position double-closed-loop control system are discussed. Then the authors discuss the type design of all sectors for the control system, and the various components of the system are given. Lastly, through the use of Matlab's Simulink software, the simulation...
Parameter method of using AR (auto-regressive) Parameters model is one of most important way to signal extraction, analyzing the acoustic signal data from different algorithms of AR Parameters Model in this paper, proves that different outcomes attributes different extractions to by simulating and the importance of preprocessing.
