We analyze a multi-layered queueing network that models a client-server system where clients and servers communicate via synchronous and asynchronous messages. The servers are organized in groups such that they form a multi-layered... more
The purpose of the traffic assignment problem is to obtain a traffic flow pattern given a set of origindestination travel demands and flow dependent link performance functions of a road network. In the general case, the traffic assignment... more

Airborne laser scanning (ALS), also referred to as airborne LiDAR (light detection and ranging), is a widely-used method for the 3D sampling of the earth's surface. The resulting point cloud is often used to derive digital terrain models... more
We investigate a characterization of underwater acoustic signals using extracted time-scale features of the propagation channel model for medium-to-high frequency range. The underwater environment over these frequencies causes multipath... more

This paper is devoted to the construction of multi-dimensional schedules for a system of uniform recurrence equations. We show that this problem is dual to the problem of computability of a system of uniform recurrence equations. We... more
The neural networks are successfully applied to many applications in different domains. However, due to the results made by the neural networks are difficult to explain the decision process of neural networks is supposed as a black box.... more
The performance of a speech recognizer is degraded drastically in reverberant environments. We proposed a novel algorithm which can model an observation signal by composition of HMMs of clean speech, noise and an acoustic transfer... more
To address the inadequacies of the mean and the α-trim mean filter, we introduce a class of non-linear filters that are a variation of the existing filters. The proposed filters use the concepts of recursion and trimming of extremities to... more

PurposeThe purpose of this paper is to propose a methodology to estimate manufacturing complexity for both machining and layered manufacturing. The goal is to take into account manufacturing constraints at design stage in order to realize... more
In this paper, we present a generic Multistage Stochastic Programming (MSSP) model considering endogenous uncertainty in some of the parameters. To address the issue that the number of non-anticipativity (NA) constraints increases... more
In this paper we compare the performance of different algorithms employed in solving frequency domain blind source separation of convolutive mixtures. The convolutive model is an extension of the instantaneous one and it allows to relax... more
Previous optimization models for the scheduling of tests for pharmaceuticals and agrochemicals, assume that the resources available for testing such as laboratories and scientists are constant throughout the testing horizon, and that all... more

As advances in process technology continue to scale down transistors, low power design is becoming more critical. Clock gating is a dynamic power saving technique that can freeze some flip-flops and prevent portion of the circuit from... more
Planning, scheduling and dispatching play critical roles in the operations of a supply chain. Their definitions are clearly given through a unified view in this paper. The distinction between planning and scheduling is analyzed from the... more
Available transfer capability (ATC) is an important metric used to measure the techno-economic viability of the transmission networks. Several methods have been presented in literature for ATC assessment, however, only some few articles... more
The graph partitioning problem consists of partitioning the vertex set of a graph into several disjoint subsets so that the sum of weights of the edges between the disjoint subsets is minimized. In this paper, robust optimization models... more
