A multistage system refers to a system consisting of multiple components, stations or stages required to finish the final product or service. Multistage systems are very common in practice and include a variety of modern manufacturing and service systems. In most cases, the quality of the final product or service produced by a multistage system is determined by complex interactions among multip...

In this work, a new constrained hybrid variational deblurring model is developed by combining the non-convex firstand second-order total variation regularizers. Moreover, a box constraint is imposed on the proposed model to guarantee high deblurring performance. The developed constrained hybrid variational model could achieve a good balance between preserving image details and alleviating ringi...

Selective excitation of the human visual cortex by patterned stimuli was examined in a randomly selected sample of normal adtdts and adults with severe monocular visual loss resulting from childhood strabismic amblyopia. Six of the eight normal eyes showed selective but variable configuration cortical evoked responses (VER, passband 0.2 to 50 Hz.) to patterned stimulation when lenses were used ...

BACKGROUND The present study was conducted to evaluate seasonal variability in the quality of pre- and post-thaw semen parameters among sperm bank donors. METHODS The first two consecutive ejaculates during the months March (spring, 92 males), June (summer, 97 males), September (autumn, 81 males) and December (winter, 97 males) were analysed. A comparison was made between sperm parameters fro...

Black musli (Curculigo orchioides Gaertn.) one of the ayurvedic dasapushpa and a rejuvenating and aphrodisiac drug. Is on the verge of extinction and needs to be conserved and cultivated. Large variations are also observed in the quality of the crude drug available in the market. Study on the quality of C. orchioides in natural habitat, under cultivation and in trade in south India showed that ...

We allow quality variations in a duopoly of locationally differentiated products a-la-Hotelling (1929). We analyze the impact of quality variations on the choices of the varieties produced. We show that in a sequential game of variety choice and subsequent quality and price choice there exist only maximal variety differentiation equilibria in pure strategies. Maximal variety differentiation is ...
