The characterization of strongly perfect graphs by a restricted list of forbidden induced subgraphs has remained an open question for a long time. The minimal strongly imperfect graphs which are simultaneous imperfect are only odd holes and odd antiholes ( E. Olaru, [9]), but the entire list is not known, in spite of a lot of particular results in this direction. In this paper we give some new ...

Abstract A deep ice core was drilled at Dome A, Antarctic Plateau, East Antarctica, which started with the installation of a casing in January 2012 and reached 800.8 m 2017. To date, total 337 successful ice-core drilling runs have been conducted, including 118 to drill pilot hole. The time 52 days, eight days were required for down reaming hole, 44 coring. average penetration depths individual...

Title of dissertation: UTILITY DRIVEN SAMPLED DATA CONTROL UNDER IMPERFECT INFORMATION Pavankumar Tallapragada, Doctor of Philosophy, 2013 Dissertation directed by: Dr. Nikhil Chopra Department of Mechanical Engineering Computer based control systems, which are ubiquitous today, are essentially sampled data control systems. In the traditional time-triggered control systems, the sampling period ...

The author identifies the two main (external and internal) dimensions of incomplete sovereignty in EMU respective caveats affecting scope single monetary policy, here described as a ‘monetary policy integration trap’. details implications caused by this curtailed both its external internal – e.g. on one hand, polarisation positions and, other effects limited European fiscal/budgetary atypical i...

The basic assumption in the traditional inventory model is that all outputs are perfect items. However, this assumption is too simplistic in the most real-life situations due to a natural phenomenon in a production process. From this it is deduced that the system produces non-perfects items which can be classified into four groups of perfect, imperfect, reworkable defective and non-reworkable d...

The effect of imperfect production processes on lot sizing decisions received a lot of attention in the literature. These efforts have been almost confined to single stage production systems. The issue of imperfect production processes has not been adequately addressed in the context of multistage production/inventory systems. In this paper, we propose a two-stage production inventory model tha...

This paper considers a modified empirical likelihood and uses it to estimate models with imperfect moment restrictions. Consistency, local normality and asymptotic optimality of the new estimator only require the local identifiability and the linear-quadratic representation. In imperfect situations, classical sandwich algorithms give bias estimations while the new estimator preserves its asympt...
