An information theoretic framework for unequal error protection is developed in terms of the exponential error bounds. The fundamental difference between the bit-wise and message-wise unequal error protection (UEP ) is demonstrated, for fixed length block codes on DMCs without feedback. Effect of feedback is investigated via variable length block codes. It is shown that, feedback results in a significant improvement in both bit-wise and message-wise UEP (except the single message case for missed detection). The distinction between false-alarm and missed-detection formalizations for message-wise UEP is also considered. All results presented are at rates close to capacity.

Unequal Error Protection: An Information-Theoretic Perspective Borade, Shashi; Nakiboğlu, Barış; Zheng, Lizhong (2009-12-01) An information-theoretic framework for unequal error protection is developed in terms of the exponential error bounds. The fundamental difference between the bit-wise and message-wise unequal error protection (UEP) is demonstrated, for fixed-length block codes on discrete memoryless channels (DMCs) without feedback. Effect of feedback is investigated via variable-length block codes. It is shown that, feedback results in a significant improvement in both bit-wise and message-wise UEPs (except the single mess...
Bit-Wise Unequal Error Protection for Variable-Length Block Codes With Feedback Nakiboğlu, Barış; Zheng, Lizhong; Coleman, Todd P (2013-03-01) The bit-wise unequal error protection problem, for the case when the number of groups of bits is fixed, is considered for variable-length block codes with feedback. An encoding scheme based on fixed-length block codes with erasures is used to establish inner bounds to the achievable performance for finite expected decoding time. A new technique for bounding the performance of variable-length block codes is used to establish outer bounds to the performance for a given expected decoding time. The inner and th...
A Control System Architecture for Control of Non-Affine in Control, Open-Loop Unstable Underactuated Systems Marangoz, Alp; Kutay, Ali Türker (2017-07-25) In this paper, a control system architecture for control of non-affine in control, open-loop unstable underactuated system is discussed. Passivization of the unactuated (internal) system dynamics achieved through perturbation of trajectories of the actuated states, which are calculated through adaptive dynamic inversion technique, based on Tikhonov's theorem. Performance of the controller is shown through simulation of two open-loop unstable and locally uncontrollable example problems.
Upper Bounds to Error Probability with Feedback Nakiboğlu, Barış (2009-08-18) A new technique is proposed for upper bounding the error probability of fixed length block codes with feedback. Error analysis is inspired by Gal lager's error analysis for block codes without feedback. Zigangirov-D'yachkov (Z-D) encoding scheme is analyzed with the technique on binary input channels and k-ary symmetric channels. A strict improvement is obtained for k-ary symmetric channels.
A verification approach for dynamics of metamodel based conceptual models of the mission space Eryılmaz, Utkan; Bilgen, Semih; Department of Information Systems (2011) Conceptual models were introduced in the simulation world in order to describe the problem domain in detail before any implementation is attempted. One of the recent approaches for conceptual modeling of the military mission space is the KAMA approach which provides a process description, a UML based notation, and a supporting tool for developing conceptual models. The prominence of the approach stems from availability of guidance and applications in real life case studies. Although the credibility of a con...
