The paper is dedicated to the study of strong duality for a problem linear copositive programming. Based on recently introduced concept set normalized immobile indices, an extended dual deduced. satisfies relations and does not require any additional regularity assumptions such as constraint qualifications. main difference with previously obtained results consists in fact that now uses neither ...

The combination of proteins with acids has been studied by Loeb I and others largely by means of hydrogen electrode measurements. The present work constitutes an attempt to apply the method of conductivity titration to the determination of the combining capacity of a protein for acids. The first work which indicated that the measurement of electrical conductivity could be used in volumetric ana...

We consider the dynamic shortest path problem in the continuous-time model because of its importance. This problem has been extensively studied in the literature. But so far, all contributions to this problem are based on the assumption that all transit times are strictly positive. However, in order to study dynamic network flows it is essential to support negative transit times since they occu...
