Formulations and valid inequalities for the heterogeneous vehicle routing problem
(Springer, 2006)
We consider the vehicle routing problem where one can choose among vehicles with different costs and capacities to serve the trips. We develop six different formulations: the first four based on Miller-Tucker-Zemlin ...
Arming civilians as a counterterror strategy: The case of the village guard system in Turkey
(Routledge, 2015)
There are currently more than 60,000 Kurdish village guards in a system that has been fighting against the PKK in Turkey for almost three decades. This article offers the first evaluation of the effectiveness of the village ...
Evidence from autoimmune thyroiditis of skewed X-chromosome inactivation in female predisposition to autoimmunity
(Nature Publishing Group, 2006)
The etiologic factors in the development of autoimmune thyroid diseases (AITDs) are not fully understood. We investigated the role of skewed X-chromosome inactivation (XCI) mosaicism in female predisposition to AITDs. One ...
Lighting monuments: reflections on outdoor lighting and environmental appraisal
(Elsevier, 2006-06)
For more than 10 years, highlighting urban pattern, revealing the artifacts in our surroundings, and providing relationships among the elements of cities, outdoor lighting practice gained more significance. The following ...
Analytical modelling of the interpixel thermal crosstalk in superconducting edge-transition bolometer arrays
(Institute of Physics Publishing Ltd., 2006)
We present an analytical thermal model to explain the crosstalk in YBCO edge-transition bolometer arrays. The verification of the model was tested on sample array devices made of 200 and 400 nm YBCO films on LaAlO3 and ...
PATIKAweb: a Web interface for analyzing biological pathways through advanced querying and visualization
(Oxford University Press, 2006-02-01)
Summary: PATIKAweb provides a Web interface for retrieving and analyzing biological pathways in the PATIKA database, which contains data integrated from various prominent public pathway databases. It features a user-friendly ...
The relationship between different price indices: evidence from Turkey
(Elsevier BV, 2006)
A possible relationship between the Consumer Price Index and the Wholesale Price Index has been analyzed for long and short-run relationships. Conventional Engle and Granger [Estimation Test Econ. 55(1987) 2251-276] and ...
Dependence of the cloud size on interactions for a trapped degenerate ultracold plasma
(Elsevier B.V., 2006)
We consider an ultracold plasma that has bosonic ions, at zero temperature. Assuming that ions are trapped by a harmonic trap, we calculate the size of the cloud for both screened and bare Coulomb interactions. Our results ...
Hub Location Problem with Allowed Routing between Nonhub Nodes
(Wiley-Blackwell, 2015)
In this study, we relax one of the general assumptions in the hub location literature by allowing routed flows between nonhub nodes. In hub networks, different flows are consolidated and routed via collection, interhub, ...
An EOQ model with multiple suppliers and random capacity
(2006)
We consider an EOQ model with multiple suppliers that have random capacities, which leads to uncertain yield in orders. A given order is fully received from a supplier if the order quantity is less than the supplier's ...
