#### Mathematical and numerical modeling of the effect of input-parameters on the flushing efficiency of plasma channel in EDM process

(Elsevier Ltd, 2013)

In the present study, the temperature distribution on the surface of workpiece and tool during a single discharge in the electrical discharge machining process has been simulated using ABAQUS code finite element software. ...

#### Distributed bounding of feasible sets in cooperative wireless network positioning

(IEEE, 2013)

Locations of target nodes in cooperative wireless sensor networks can be confined to a number of feasible sets in certain situations, e.g., when the estimated distances between sensors are larger than the actual distances. ...

#### Moments of conditional sojourn times in finite capacity M/M/1/N-PS processor sharing queues

(Institute of Electrical and Electronics Engineers, 2012)

Moments of sojourn times conditioned on the length of an admitted job are derived for a finite capacity M/M/1/N-PS processor sharing queue. The mean conditional sojourn time is given in closed form whereas an expression ...

#### Binary integer formulation for mixed-model assembly line balancing problem

(Pergamon Press, 1998-04-01)

The assembly line balancing problem has been a focus of interest to the academicians of production/operations
management for the last 40 years. Although there are numerous studies published
on the various aspects of the ...

#### Metal-insulator transition induced by random dipoles

(American Physical Society, 2013)

We study the localization properties of a test dipole feeling the disordered potential induced by dipolar impurities trapped at random positions in an optical lattice. This random potential is marked by correlations which ...

#### New product success: is it really controllable by managers in highly turbulent environments?

(Wiley-Blackwell Publishing, 2008)

This research proposes and tests a model of direct and indirect effects linking four antecedents to new product success: (1) a proactive strategic orientation along with enabling (2) organic organizational structures should ...

#### A concave-convex procedure for TDOA based positioning

(IEEE, 2013)

This letter investigates the time-difference-of-arrival based positioning problem in wireless sensor networks. We consider the least-mean absolute, i.e., the ℓ1 norm, minimization of the residual errors and formulate the ...

#### Phonon confinement and screening effects on the polaron energy in quantum wires

(Institute of Physics Publishing Ltd., 1995)

We study the contribution of confined phonons to the polaron energy in quantum-well wires. We use a dispersionless, macroscopic continuum model to describe the phonon confinement in quantum wires of square cross section. ...

#### Efficient use of closed-form Green's functions for the analysis of planar geometries with vertical connections

(Institute of Electrical and Electronics Engineers, 1997-05)

An efficient and rigorous method for the analysis of planarly layered geometries with vertical metallizations is presented. The method is based on the use of the closed-form spatial-domain Green's functions in conjunction ...

#### An inventory problem with two randomly available suppliers

(Institute for Operations Research and the Management Sciences, 1997)

This paper considers a stochastic inventory model in which supply availability is subject to random fluctuations that may arise due to machine breakdowns, strikes, embargoes, etc. It is assumed that the inventory manager ...
