Minimizing total tardiness in a scheduling problem with a learning effect
(Elsevier Science Inc, 2007)
Minimizing of total tardiness is one of the most studied topics on single machine problems. Researchers develop a number of optimizing and heuristic methods to solve this NP-hard problem. In this paper, the problem of ...
Poly[[diaquacaesium(I)]bis(μ 3 -3-carboxypyrazine-2-carboxylato)]
(Int Union Crystallography, 2007)
The asymmetric unit of the title compound, [Cs(C6H3N2O4)(2)(H2O)(2)](n), contains one Cs-I cation on an inversion centre, one 3-carboxypyrazine-2-carboxylate anion and one water molecule. In the crystal structure, each ...
Approximation of functions of two variables by certain linear positive operators
(Springer India, 2007)
We introduce certain linear positive operators and study some approximation properties of these operators in the space of functions, continuous on a compact set, of two variables. We also find the order of this approximation ...
Effect of austenitization heat treatment on the magnetic properties of Fe-40wt% Ni-2wt% Mn alloy
(Journal Of Univ Of Science And Technology Beijing, 2007)
The effect of austenitization heat treatment on magnetic properties was examined by means of Mossbauer spectroscopy on an Fe-40wt%Ni-2wt%Mn alloy. The morphology of the alloy was obtained by using scanning electron microscopy ...
Martensitic transformation and magnetic properties of Fe-24.5%Ni-4.5%Si alloy
(Maney Publishing, 2007)
The effect of austenitising temperature and cooling rate on the morphology and magnetic properties of martensite in Fe-24-5%Ni-4-5%Si alloy has been studied by means of scanning electron microscopy, Mbssbauer spectroscopy ...
Late dissemination of ependymoma: case report
(Soc Espanola Neurocirugia, 2007)
Spinal cord dissemination over 10 years after surgical removal of the fourth ventricle ependymoma without local recurrence is extremely rare. A 49-year-old male underwent a macroscopically gross total removal of the fourth ...
