Many dynamic resource allocation and on-line load balancing problems can be modeled by processes that sequentially allocate balls into bins. The balls arrive one by one and are to be placed into bins on-line without using a centralized controller. If n balls are sequentially placed into n bins by placing each ball in a randomly chosen bin, then it is widely known that the maximum load in bins i...

Maximum vertical forces produced by flying animals can be difficult to identify unequivocally, but potentially indicate general limits to aerodynamic force and muscle power output. We used two methods (i.e. incremental addition of supplemental mass and asymptotic load lifting) to determine both the intraspecific allometry of and methodological differences in estimates of maximum flight performa...

Oral glucose tolerance test with 50g glucose was carried out with and without simultaneous oral administration of 3g calcium lactate. Blood sugar and serum immunoreactive insulin (IRI) were measured before and 30, 60, 90 and 120min after glucose load in 11 diabetics and 11 non-diabetics. Similar oral glucose tolerance test was performed with and without intravenous administration of 10ml 8.5% c...

Earlier models of virus evolution during single infections do not include target cell limitation. Here we extend the basic mathematical framework of these theories and study the effect of target cell limitation on the evolution of antigenic variation, increasing replication rates and increasing virus load. We find that target cell limitation provides a selection pressure against antigenic diver...

This paper shows that the Principal Component Analysis, a compression method widely used in statistical anaylsis and image processing, can be efficiently implemented in a network of wireless sensors. The proposed scheme proves to be particularly suitable to sensor networks as it allows to reduce the network load while retaining a maximum amount of variance from sensor measurements. We present t...

Tooth root crack is considered as one of the crucial causes of failure in the gearing system and it occurs at the tooth root due to an excessive bending stress developed in the root region. The modern power transmission gear drives demand high bending load capacity, increased contact load capacity, low weight, reduced noise and longer life. These subsequent conditions are satisfied by the aid o...
