The network design problem with relays
(Elsevier, 2007)The network design problem with relays (NDPR) is defined on an undirected graph G = (V, E, K), where V = {1, ..., n} is a vertex set, E = {(i, j) : i, j ∈ V, i < j} is an edge set. The set K = {(o(k), d(k))} is a set ... 
A new method for the computation of all stabilizing controllers of a given order
(Taylor & Francis, 2005)A new method is given for computing the set of all stabilizing controllers of a given order for linear, time invariant, scalar plants. The method is based on a generalized HermiteBiehler theorem and the successive application ... 
Objectoriented query language facilitating construction of new objects
(Elsevier, 1993)In objectoriented database systems, messages can be used to manipulate the database; however, a query language is still a required component of any kind of database system. In the paper, we describe a query language for ... 
On moments of discrete phasetype distributions
(Springer, Berlin, Heidelberg, 2005)Recently, an efficient and stable method to compute moments of first passage times from a subset of states classified as safe to the other states in ergodic discretetime Markov chains (DTMCs) has been proposed. This paper ... 
On Roth, Korth, and Silberschatz's extended algebra and calculus for nested relational databases
(1992)We discuss the issues encountered in the extended algebra and calculus languages for nested relations defined by Roth, Korth, and Silberschatz. Their equivalence proof between algebra and calculus fails because of the ... 
On the set of all stabilizing firstorder controllers
(IEEE, 2003)A computational method is given for determining the set of all stabilizing proper firstorder controllers for finite dimensional, linear, time invariant, scalar plants. The method is based on a generalized HermiteBiehler theorem. 
Optimal control of a twostage stochastic hybrid manufacturing system with Poisson arrivals and exponential service times
(IEEE, 2005)Extending earli'er work on singlestage stochastic hybrid system models, we consider a twostage stochastic hybrid system where the job arrivals are represented through a Poisson process, and the service times required to ... 
Optimal shorttime Fourier transform for monocomponent signals
(IEEE, 2004)New methods of improving the shorttime Fourier transform representation of signals have recently emerged. These methods use linear canonical transforms to bring the signal into a minimal timebandwidth product form. Here ... 
Projections onto convex sets (POCS) based optimization by lifting
(IEEE, 2013)A new optimization technique based on the projections onto convex space (POCS) framework for solving convex and some nonconvex optimization problems are presented. The dimension of the minimization problem is lifted by ... 
Pulse shape design using iterative projections
(IEEE, 200509)In this paper, the pulse shape design for various communication systems including PAM, FSK, and PSK is considered. The pulse is designed by imposing constraints on the time and frequency domains constraints on the ... 
Quantum canonical transformations in starproduct formalism
(IOP, 2013)We study construction of the starproduct version of three basic quantum canonical transformations which are known as the generators of the full canonical algebra. By considering the fact that starproduct of cnumber ... 
Query model for objectoriented databases
(IEEE, 199304)A query language should be a part of any database system. While the relational model has a well defined underlying query model, the objectoriented database systems have been criticized for not having such a query model. ... 
Reconstruction of scalar diffraction field from distributed data points over 3D space
(IEEE, 2007)Diffraction field computation is an important task in the signal conversion stage of the holographic 3DTV. We consider an abstract setting, where the diffraction field of the desired 3D scene to be displayed is given by ... 
Restoration of errordiffused images using projection onto convex sets
(2001)In this paper, a novel inverse halftoning method is proposed to restore a continuous tone image from a given halftone image. A set theoretic formulation is used where three sets are defined using the prior information ... 
A search method for optimal control of a flow shop system of traditional machines
(Elsevier, 2010)We consider a convex and nondifferentiable optimization problem for deterministic flow shop systems in which the arrival times of the jobs are known and jobs are processed in the order they arrive. The decision variables ... 
Simple functors of admissible linear categories
(Springer, 2016)Generalizing an idea used by Bouc, ThÃ©venaz, Webb and others, we introduce the notion of an admissible Rlinear category for a commutative unital ring R. Given an Rlinear category (Formula presented.) , we define an ... 
Threedimensional motion and densestructure estimation using convex projections
(SPIE, 199702)We propose a novel method for estimating the 3D motion and dense structure of an object form its two 2D images. The proposed method is an iterative algorithm based on the theory of projections onto convex sets (POCS) that ... 
Towards finding global representations of the efficient set in multiple objective mathematical programming
(John Wiley & Sons, 1997)We propose and justify the proposition that finding truly global representations of the efficient sets of multiple objective mathematical programs is a worthy goal. We summarize the essential elements of a general global ... 
Using data compression for increasing memory system utilization
(Institute of Electrical and Electronics Engineers, 200906)The memory system presents one of the critical challenges in embedded system design and optimization. This is mainly due to the everincreasing code complexity of embedded applications and the exponential increase seen in ...
