Data Communication and Computer Networking is a traditional undergraduate CS course. Classic teaching focuses on communication protocol and algorithm analysis, plus socket programming, and often deploys simulator to reinforce theoretical concepts. However, in our CS department with only undergraduate students, this approach appears to be hard to meet students’ expectation to handle real world n...

We analyze the density distribution of marine sediments using density samples taken from 716 drill sites of the Deep Sea Drilling Project (DSDP). The samples taken within the upper stratigraphic layer exhibit a prevailing trend of the decreasing density with the increasing ocean depth (at a rate of -0.05 g/cm(3) per 1 km). Our results confirm findings of published studies that the density nonli...

Firms’ fob prices can vary depending on the distance to the destination market for two reasons: (i) firms can charge a different markup (ii) they can offer a product with slightly different quality. In theoretical models, distance generally covers transport costs. This paper shows that the response of firms’ prices to changes in distance to the destination market depends on the formulation of t...

"The educational, occupational, industrial and income characteristics of immigrants in Canada, 1971-1986, are considered in the context of postindustrial structural changes in the economic and social system, including declining primary and secondary sectors. Seven alternative theoretical models are reviewed. A composite model of 'segmented structural change' is found to correspond more closel...

Surface reflectivity effects on coherent backscattering have been studied by using variable-reflectivity mirrors at the sample surface. Photon-transport parameters obtained from coherent backscattering were found to be significantly improved by using current theoretical models for samples with high surface reflectivity.

Advances in experimental techniques and in theoretical models have improved our understanding of protein crystallization. However, they have also left open questions regarding the protein phase behavior and self-assembly kinetics, such as why (nearly) identical crystallization conditions can sometimes result in the formation of different crystal forms. Here, we develop a patchy particle model w...

Ethnic German Immigration from Eastern Europe and the former Soviet Union to Germany: the Effects of Migrant Networks This paper employed a widely accepted theoretical concept, the ‘theory of migrant networks’ to look at the recent immigration and absorption experience of ethnic Germans (Aussiedler) from Eastern Europe and the former Soviet Union in Germany. Consistent with network theory, the ...

This paper proposes a theoretical concept of cross cultural discursive competence (CCDC). As an initial step, it reviews and critiques a series of in the relevant areas of intercultural communication, genre analysis and contrastive rhetoric and points out that it is imperative to explore what CCDC is composed of. In addition, we also need to strengthen cross-cultural genre study in the light of...

In this paper we present general theoretical models to improve the coordination between team members. We apply these models for passing, a coordination problem in soccer, and demonstrate the usefulness of these models. For the improvement of the team a trainer has been used to extract good passing behavior out of a set of games. The trainer improves this behavior and gives advice for the agents...

In this paper, I consider theoretical models of the decay via photobleaching of a sample of surface-immobilized fluorescent molecules excited by a spatially varying laser intensity profile. I show that, with mild restrictions on the photobleaching mechanism, the fluorescence decay measured in a nonuniform excitation profile is always nonexponential. Under the same conditions, the fluorescence d...
