On the use of evolutionary coupling for software architecture recovery
(IEEE, 2021)Software architecture documentation can be partially obtained automatically by means of software architecture recovery tools. These tools mainly cluster software modules to provide a high level structural organization of ... -
On the use of machine learning for predicting defect fix time violations
(Science and Technology Publications, 2022)Accurate prediction of defect fix time is important for estimating and coordinating software maintenance efforts. Likewise, it is useful to predict whether or not the initially estimated defect fix time will be exceeded ... -
On the volume of the shrinking branching Brownian sausage
(The Institute of Mathematical Statistics and the Bernoulli Society, 2020)The branching Brownian sausage in R-d was defined in [4] similarly to the classical Wiener sausage, as the random subset of R-d scooped out by moving balls of fixed radius with centers following the trajectories of the ... -
On throughput-delay optimal access to storage clouds via load adaptive coding and chunking
(IEEE, 2016-08)Recent literature including our past work provides analysis and solutions for using: 1) erasure coding; 2) parallelism; or 3) variable slicing/chunking (i.e., dividing an object of a specific size into a variable number ... -
On weak feller continuity properties of non-linear filters
(IEEE, 2019)Weak Feller property of controlled and control free Markov chains leads to many desirable properties. In control-free setups this leads to the existence of invariant probability measures for compact spaces and applicability ... -
On ‘‘Radiative transfer in three-dimensional rectangular enclosures containing inhomogeneous,anisotropically scattering media’’
(Elsevier, 2010-07)Our 1985 paper (JQSRT 1985; 33: 533–549) reported the result of the research we conducted back then to better understand heat transfer processes in large-scale combustion chambers, especially in pulverized coal-fired ... -
The one-warehouse multiretailer problem with an order-up-to level inventory policy
(Wiley, 2010-10)We consider a two-level system in which a warehouse manages the inventories of multiple retailers. Each retailer employs an order-up-to level inventory policy over T periods and faces an external demand which is dynamic ... -
Online association rule mining over fast data
(IEEE, 2013)To extract useful and actionable information in real-time, the information technology (IT) world is coping with big data problems today. In this paper, we present implementation details and performance results of ReCEPtor, ... -
Online real-time simulation of vehicles
(IEEE, 2020-09)Real-time simulation of a vehicle accessible as a server process on a network is needed in multiple use cases. One such use case is coordinated driving. Coordinated driving will eventually require us to control vehicles ... -
Operation altitude optimization of solar-powered rotary-wing UAVs for FSO backhauling
(IEEE, 2023)Free space optical communication (FSO) has emerged as an alternative backhauling technology. It provides a line-of-sight (LOS) link with a capacity comparable to fiber optics and much higher than those that can be supported ... -
Operations research approaches for improving coordination, cooperation, and collaboration in humanitarian relief chains: A framework and literature review
(Elsevier, 2023)Given the considerable number of actors in the humanitarian space, coordination is essential for successful disaster response. Furthermore, the sheer size of challenges and limited resources increasingly highlight the need ... -
Optical and radiative properties of individual and hybrid nanosuspensions: The effects of similar and dissimilar particle agglomerates on thermal radiation
