On robust solutions to linear least squares problems affected by data uncertainty and implementation errors with application to stochastic signal modeling
(Elsevier, 2004)Engineering design problems, especially in signal and image processing, give rise to linear least squares problems arising from discretization of some inverse problem. The associated data are typically subject to error in ... 
On semidefinite bounds for maximization of a nonconvex quadratic objective over the ℓ1 unit ball
(E D P Sciences, 2006)We consider the nonconvex quadratic maximization problem subject to the ℓ1 unit ball constraint. The nature of the l1 norm structure makes this problem extremely hard to analyze, and as a consequence, the same difficulties ... 
On separating cover inequalities for the multidimensional knapsack problem
(Elsevier, 200706)We propose a simple and a quite efficient separation procedure to identify cover inequalities for the multidimensional knapsack problem. It is based on the solution of a conventional integer programming model. Solving ... 
On testing independence with right truncated data
(Elsevier, 199712)Inference with bivariate data gained considerable interest recently, See eg.[1],[10],[12]. All of these studies howrver consider estimation of the bivariate distribution function under various bivariate censoring models. ... 
On the accuracy of uniform polyhedral approximations of the copositive cone
(Taylor & Francis, 2012)We consider linear optimization problems over the cone of copositive matrices. Such conic optimization problems, called copositive programs, arise from the reformulation of a wide variety of difficult optimization problems. ... 
On the consistency of a twosample matching test
(Taylor & Francis, 1996)Let {X k} and {Y k}, 1 ≤ k ≤n be the order statistics of independent random samples from continuous distribution function F and G respectively. To test the null hypothesis H 0 : G = F, known, against the alternative H 1 : ... 
On the distribution of throughput of transfer lines
(Palgrave Macmillan, 2000)Transfer lines simply characterise the interrelationship of manufacturing stages with their buffers and they are used to model the key features of such manufacturing environments with simplifying assumptions. There is a ... 
On the Hajek projection for truncated and censored data
(Scientific Publishers, 1993)Large sample properties of the productlimit estimators for truncated or censored data are usually achieved via the empirical cumulative hazard function estimators. Hajek projection of the empirical cumulative hazard ... 
On the minimum volume covering ellipsoid of ellipsoids
(Society for Industrial and Applied Mathematics, 2006)Let S denote the convex hull of m fulldimensional ellipsoids in ℝn. Given ε > 0 and δ > 0, we study the problems of computing a (1 + ε)approximation to the minimum volume covering ellipsoid of S and a (1 + δ)nrounding ... 
On the modeling of CO2 EUA and CER prices of EUETS for the 2008–2012 period
(John Wiley and Sons, 2016)Increased consumption of fossil fuels in industrial production has led to a significant elevation in the emission of greenhouse gases and to global warming. The most effective international action against global warming ... 
On the optimality of the greedy solutions of the general knapsack problems
(Taylor & Francis, 1992)In this paper we submit a unified discussion of some closely related results which were achieved independently in number theory and integer programming, and we partially generalize them. In the unified discussion we treat ... 
On the Sprocedure and some variants
(Springer, 2006)We give a concise review and extension of Sprocedure that is an instrumental tool in control theory and robust optimization analysis. We also discuss the approximate SLemma as well as its applications in robust optimization. 
On the singleassignment phub center problem
(Elsevier, 2000)We study the computational aspects of the singleassignment phub center problem on the basis of a basic model and a new model. The new model's performance is substantially better in CPU time than different linearizations ... 
On the use of phasetype distributions for inventory management with supply disruptions
(John Wiley & Sons, 2011)Maintaining the continuity of operations becomes increasingly important for systems that are subject to disruptions due to various reasons. In this paper, we study an inventory system operating under a (q, r) policy, where ... 
Onmachine fabrication of PCD and WC micro end mills using micro electro discharge machining
(Inderscience Enterprises Ltd., 2014)Micro electro discharge machining (μ EDM) process can be used to fabricate micromilling tools of different geometries from tungsten carbide (WC) and polycrystalline diamond (PCD). The noncontact nature of EDM process ... 
Online Contextual Influence Maximization in social networks
(Institute of Electrical and Electronics Engineers Inc., 2017)In this paper, we propose the Online Contextual Influence Maximization Problem (OCIMP). In OCIMP, the learner faces a series of epochs in each of which a different influence campaign is run to promote a certain product in ... 
Online contextual influence maximization with costly observations
(IEEE, 201906)In the online contextual influence maximization problem with costly observations, the learner faces a series of epochs in each of which a different influence spread process takes place over a network. At the beginning of ... 
Operationbased flowtime estimation in a dynamic job shop
(Elsevier, 2002)In the scheduling literature, estimation of job owtimes has been an important issue since the late 1960s. The previous studies focus on the problem in the context of due date assignment and develop methods using aggregate ... 
Optimal allocation and processing time decisions on nonidentical parallel CNC machines: ε{lunate}constraint approach
(ElsevierElsevier, 20071201)When the processing times of jobs are controllable, selected processing times affect both the manufacturing cost and the scheduling performance. A well known example for such a case that this paper specifically deals with ... 
Optimal allocation with costly inspection and discrete types under ambiguity
(Taylor & Francis, 2017)We consider the following problem: a principal has a good to allocate among a collection of agents who attach a private value to receiving the good. The principal, instead of using monetary transfers (i.e. charging the ...
