embedded systems are becoming a suggestive target for code injection attacks in recent years. software protection mechanisms in general computers are not usually applicable in embedded systems as they come with limited resources like memory and processor. in this paper we investigate side channel characteristics of embedded systems and their usability in code injection attack detection. the arc...

a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...

in the present study, a new modelling technique was developed for the modelling and analysis of hyperchaotic systems using an expert system based on wavelet decompositions and the adaptive neuro-fuzzy inference system (anfis). the success and superior properties of this new expert system were shown by applying the hyperchaotic chen system which is a hyperchaotic system. the obtained expert s...

شبیه‏سازی رایانه‏ای رفتار آتش امکان تجزیه‌وتحلیل مشخصات اصلی گسترش و رفتار آتش را در ناحیه‌ای معین فراهم می‏سازد. تغییرات زمانی و مکانی رفتار آتش می‏تواند با استفاده از یکی از مدل‏های نیمه‌فیزیکی یا تجربی توسعه‌یافته در سال‏های گذشته پیش‏بینی شود. این پژوهش اثر شرایط مختلف رطوبت مادة سوختنی را بر گسترش و رفتار آتش‏سوزی در تیرماه 1390 در پارک ملی گلستان، با استفاده از سیستم‏های شبیه‏سازی FARSITE...

in recent years mobile networks have expanded dramatically, compared with other wireless networks. routing protocols in these networks are designed with the assumption that there is no attacker node, so routing protocols are vulnerable to various attacks in these networks. in this paper, we review the network layer attacks and then we simulate the impact of black hole attack on ad hoc on demand...

Repairable standby system’s study and analysis is an important topic in reliability. Analytical techniques become very complicated and unrealistic especially for modern complex systems. There have been attempts in the literature to evolve more realistic techniques using simulation approach for reliability analysis of systems. This paper proposes a hybrid approach called as Markov system ...

In previous studies, active suspension system in conventional powertrain systems was investigated. This paper presents the application of active suspension system in parallel hybrid electric vehicles as a novel idea. The main motivation for this study is investigation of the potential advantages of this application over the conventional one. For this purpose, a simultaneous simulation is develo...

Building performance simulation is being increasingly deployed beyond the building design phase to support efficient building operation. Specifically, the predictive feature of the simulation-assisted building systems control strategy provides distinct advantages in view of building systems with high latency and inertia. Such advantages can be exploited only if model predictions can be relied u...
