We consider the use of well-known dual capacity bounding technique for deriving upper bounds on indecomposable finite-state channels (FSCs) with finite input and output alphabets. In this technique, are obtained by choosing suitable test distributions sequence channel outputs. propose that arise from certain graphical structures called Q-graphs. As we show in paper, advantage choice distributio...

Queueing networks with finite capacity queues and blocking are applied to model systems with finite resources and population constraints, such as computer and communication systems, as well as traffic, production and manufacturing systems. Various blocking types can be defined to represent different system behaviors. When a customer attempts to enter a full capacity queue blocking occurs. The a...

temperature profile determination in soils under adverse conditions of variable heat capacity and conductivity is a rather hard task. the heat capacity and conductivity are moisture dependent and both vary with the soil density. moisture movement on the other hand is temperature dependent and so the two interact. no single mathematical formulae as yet exists for anticipating the temperature dis...

large capacity cylindrical tanks are used to store a variety of liquids. their satisfactoryperformance during earthquake is crucial for modern facilities. in present paper, the behavior of cylindricalconcrete tanks under harmonic excitation is studied using the finite element method. liquid sloshing, liquidviscosity and wall flexibility are considered and additionally excitation frequency, liqu...

We derive a regularized formula for the common randomness assisted entanglement transmission capacity of finite arbitrarily varying quantum channels (AVQC’s). For finite AVQC’s with positive capacity for classical message transmission we show, by derandomization through classical forward communication, that the random capacity for entanglement transmission equals the deterministic capacity for ...

We develop a characterization of fading models, which assigns a number called logarithmic Jensen’s gap to a given fading model. We show that as a consequence of a finite logarithmic Jensen’s gap, approximate capacity region can be obtained for fast fading interference channels (FF-IC) for several scenarios. We illustrate three instances where a constant capacity gap can be obtained as a functio...

in this paper, finding dynamic load carrying capacity (dlcc) of flexible link manipulators in point to-point motion was formulated as an optimal control problem. the finite element method was employed for modelling and deriving the dynamic equations of the system. the study employed indirect solution of optimal control for system motion planning. due to offline nature of the method, many diffic...

The amplitude-constrained capacity of a scalar Gaussian channel is shown to be achieved by a unique discrete random variable taking on a finite number of values. Necessary and sufficient conditions for the distribution of this random variable are obtained. These conditions permit determination of the random variable and capacity as a function of the constraint value. The capacity of the same Ga...
