This paper presents an approach for calculating the capacity of multi-service CDMA networks with soft blocking using general insensitive traffic models. The system is modelled as a multi-rate traffic flow model with state dependent blocking probabilities which have to fulfil specific requirements for maintaining reversibility of the model. Performance calculations are carried out by generalisin...

This research examined how social self-efficacy, collective self-esteem, and need to belong can be used to predict teens’ use of social media. The particular focus was on how these social psychological variables together with social media use account for variation in teens’ participation in a flash mob—an exemplar of 21-century collective action. Empirical data come from a survey of teens in a ...

In the multiple authors case, the name with ∗ is the speaker.

The matching properties of the threshold voltage, substrate factor, and current factor of MOS transistors have been analyzed and measured. Improvements to the existing theory are given, as well as extensions for long-distance matching and rotation of devices. Matching parameters of several processes are compared. The matching results have been verified by measurements and calculations on severa...

In this article, we combine the DLA model of Witten and Sander with ideas from optimal transportation. We propose a modification of the DLA model in which the probability of sticking is inversely proportional to the additional transport cost from the point to the root. We used a family of cost functions parametrized by a parameter α as studied in ramified optimal transportation. α < 0 promotes ...

The performance of a large (3x3 cm 2) streamer tube cell in drift mode is shown. The detector space resolution has been studied using cosmic muons crossing an high precision silicon telescope. The experimental results are compared with a GARFIELD simulation.

Urban Freight Distribution (UFD) represents a very important activity in terms of cities economy, but can also be a problem for the daily life of citizens, due to traffic, noise and environmental contamination. Therefore UFD activities must be managed cautiously, to avoid or minimise external negative effects. In this context, this research aims to evaluate existing UFD measures, ranking them f...

In a previous paper [3] the author together with prof. dr. Finston constructed a class of UFDs An,m where n,m ∈ N ∗. These rings are all stably equivalent (An,m[T ] ∼= Ap,q[T ] for all n,m, p, q) but are only isomorphic themselves if (n,m) = (p, q). These examples are the first UFD examples over a characteristically closed field satisfying this behavior. In this paper, we describe the methods u...
