Traffic class assignment for mixed-criticality frames in TTEthernet

Analysis methods for mixed-criticality applications on TTEthernet-based distributed architectures

More and more, we can see how embedded systems are given great responsibility in applications where their malfunctioning could have catastrophic e ects. Often, embedded systems are used in areas where timing constraints need to be satis ed. For the hard real-time embedded systems it is important not only to produce the correct computation result, but also to deliver it at the correct moment in ...

An Extension for AADL to Model Mixed-Criticality Avionic Systems Deployed on IMA architectures with TTEthernet

Integrated modular avionics architectures combined with the emerging SAE TTEthernet standard provides a strong infrastructure for the deployment of mixed-critical avionic applications having stringent safety, reliability and performance requirements. The integration of such systems is a very complex and challenging engineering task. Therefore, a model-based approach, which endows system enginee...

DSD Approach for Criticality Assignment in

tight frame approximation for multi-frames and super-frames

در این پایان نامه یک مولد برای چند قاب یا ابر قاب تولید شده تحت عمل نمایش یکانی تصویر برای گروه های شمارش پذیر گسسته بررسی خواهد شد. مثال هایی از این قاب ها چند قاب های گابور، ابرقاب های گابور و قاب هایی برای زیرفضاهای انتقال پایاست. نشان می دهیم که مولد چند قاب تنک نرمال شده (ابرقاب) یکتا وجود دارد به طوری که مینیمم فاصله را از ان دارد. همچنین مسایل مشابه برای قاب های دوگان مطرح شده و برخی ...

Heavy Traffic Performance of a Class of Channel Assignment Algorithms*

In this paper we present a study of the performance of a general class of channel assignment algorithms. These algorithms, which we call R-algorithms, are completely characterized by the set of carried-traffic “states” which they allow. We shall see that for any such algorithm, there is a closed-form expression for the carried t r a c function, which lends itself to several kinds of asymptotic ...
