With the introduction of trust mechanism into the wireless ad hoc network, security can be greatly improved, because trust information is shared among all nodes in the network. However, such a mechanism also has the potential vulnerability if the so-called 'big-mouth' nodes broadcast wrong trust information. Some measures have to be taken to filter the received trust information before it is fed to...
For the design and performance evaluation of advanced wireless communication systems employing multiple-input multiple-output (MIMO) technologies, realistic MIMO channel models with a good tradeoff between accuracy and complexity are indispensable. This paper compares the statistical properties of the two latest standardized MIMO channel models: Long Term Evolution-Advanced (LTE-A) and IMT-Advanced...
Although the ICEMC measurement standards at present provides a test program guideline for system under test to simplify the EMC test, papers are suggested that different programs running on such systems do have their EMC effects. This paper proposes an efficient and flexible methodology to simulate irregular and long time instruction current waveform. This methodology is based on ICEM model and is...
Other papers have suggested that different application programs running on a digital system have their own EMC effects. This paper proposes two efficient and flexible techniques to improve the simulation efficiency of techniques instruction current waveform proposed by our laboratory. Experimental results show the efficiency is improved while the simulation quality remains the same.
In this paper, modeling and simulation of high-pressure urea synthesis loop has been studied. The extended electrolytic UNIQUAC equation has been used to describe the nonideality of liquid phase of NH 3 –CO 2 –H 2 O–urea system under high pressure and high temperature, and the perturbed-hard-sphere (PHS) equation of state has been used to predict the vapor fugacity coefficients...
