In this paper an interactive game is described, that has been developed for a company using new technologies for raising awareness at job fairs. An already existing framework of a game terminal for job fairs is used. The corporate identity, the content of the advertised job, but also the attraction of a young and technologically interested audience is combined in a game in order to develop an i...

In colocated multi-user Virtual Reality applications, relative user positions in the virtual environment need to match their physical tracking space. A mismatch between and real might lead harmful events such as collisions. This paper examines three calibration methods that enable scenarios for SLAM-tracked head-mounted displays without an external system. Two of these methods—fixed-point marke...

Mining interaction patterns may lead to important observations in a variety of domains such as ecology, biology, epidemiology, earth science and transportation. For example, in biology, it is well known that Nile crocodiles are often seen together with Egyptian plovers, showing a pattern of colocation. Conversely, there is usually competition between the same kind of species which yields patter...

The goal of this paper is to evaluate cryogenics-based energy storage concepts: A thermo-electric energy storage unit, which uses surplus electricity while liquefying a gas, subsequently stored at cryogenic temperature. Here we review and evaluate concepts for power generation while regasifying the liquefied gas (cryogen) using an exergetic analysis. Two cold exergy recovery cycle configuration...

To examine what, if any, are the differences in how activities are coordinated within-firms vs. between-firms we conducted interviews with 32 project managers regarding 60 projects in the offshore software services industry. Uniquely, our projects were sampled along two dimensions: (1) co-location vs. spatial distribution and (2) were delivered by groups of individuals from a single firm vs. fr...

JEL Classifications: JI, R2 College educated couples are increasingly located in large metropolitan areas. These areas were home to 33 percent of all college educated couples in 1940, 40 percent in 1970, and 48 percent in 1990. We investigate whether this trend can be explained by increasing urbanization of the college educated or the growth of dual career households and the resulting severity ...

Infrastructure as a Service pricing models for resources are meant to reflect the operational costs and profit margins for providers to deliver virtualized resources to customers subject to an underlying Service Level Agreements (SLAs). While the operational costs incurred by providers are dynamic – they vary over time depending on factors such as energy cost, cooling strategies, and aggregate ...

Opportunistic networking protocols have recently started to emerge in different contexts, ranging from vehicular communications and remote populations connectivity to wildlife monitoring. These protocols are mainly based on the ability to exploit asynchronous communication among hosts who can act as carriers for the messages which are first stored and transported, and then delivered when the de...
