Two Heuristic Approaches for the Total Tardiness Problem



Two approaches to creating a turbulence model with increased temporal accuracy
Aggul, Mustafa; Kaya Merdan, Songül; Labovsky, Alexander E. (2019-10-01)
When modeling a turbulent fluid flow, an Approximate Deconvolution Model (ADM) is sometimes chosen - in particular, due to the high order spatial accuracy. A method has been presented in [1], that demonstrates an approach to increase the temporal accuracy of the ADM, by combining it with the Deferred Correction method (DCM). The resulting model, DC-ADM, is at least second order accurate in both space and time, and theoretically an arbitrarily high order of accuracy is achievable, provided that enough comput...
Two Alternate Methods for Information Retrieval from Turkish Radiology Reports
Hadimli, Kerem; Yoendem, Meltem Turhan (2011-09-28)
Turkish is an highly agglutinative language and this poses problems in information retrieval from Turkish free-texts. In this paper one rule based and one data driven alternate methods for information retrieval from Turkish radiology reports are presented. Both methods do not utilize any medical lexicon or ontology, although inherent medical information within the training reports exist. Performance is measured and evaluated as a retrieval problem.
Two approximation schemes to the bound states of the Dirac-Hulthen problem
IKHDAİR, SAMEER; Sever, Ramazan (IOP Publishing, 2011-09-02)
The bound-state (energy spectrum and two-spinor wavefunctions) solutions of the Dirac equation with the Hulthen potential for all angular momenta based on the spin and pseudospin symmetry are obtained. The parametric generalization of the Nikiforov-Uvarov method is used in the calculations. The orbital dependence (spin-orbit-and pseudospin-orbit-dependent coupling too singular 1/r(2)) of the Dirac equation are included to the solution by introducing a more accurate approximation scheme to deal with the cent...
Two types of collusion in a model of hierarchical agency
Bac, Mehmet; Küçükşenel, Serkan (Mohr Siebeck, 2006-06-01)
The standard ex post type of collusion is a supervisor-agent agreement to misrepresent the outcome of supervision. Under ex ante collusion the agent makes a side transfer to the supervisor, who, in return, stops monitoring the agent's productivity. Extending TIROLE'S [1986] model of hierarchy to include ex ante collusion and supervision costs, we show that the principal can ignore ex ante collusion and the supervisor's incentive constraint if supervision technology is likely to generate information at a low...
Two new indices for the assessment of regional transmission connection capacities
Güverçinci, Ali Haydar; Göl, Murat; Department of Electrical and Electronics Engineering (2017)
Traditionally electrical power industry has been regulated and monopolized. However, since 1980s it has undergone a period of restructuring throughout the world. This privatization procedure has made the planning and operation of the generation, transmission and distribution parts of power system relatively more independent and disconnected. The transmission system planners lost their direct control over plant investments. As a result, planning of the transmission system became more complex than it ever was...
