Communication Path

Guaranteeing data transmission between modules is the key for application development of modular robotic systems. In a multi-channel modular robotic system, intersection modules play an essential role of communication channel selection in controlling data flow toward desired destinations. The gradient-based routing algorithm is an ideal solution to create an one-way communication path from any robotic module to a designated destination. To create bi-directional communication for a communication path of robotic configuration, virtual pheromone-based routing algorithm is a promising mechanism for intersection modules due to its simplicity and distributivity. In this paper, we address a virtual pheromone based network flow control based on the integration of gradient and virtual pheromone-based routing algorithms. We validated this method through an education and entertainment application using our newly developed modular robotic system.

AbstractTwo aerodynamic concepts theorized in the early twentieth century – laminar-flow control and flying wings – offer the potential for more efficient aircraft. However, despite compelling advantages on paper and optimistic predictions, the fuel-saving benefits of these technologies have not yet been fully realized. This paper documents British work on these concepts, with a particular focus on laminar-flow control. Faced with an increasingly difficult funding context and a lack of a clear military rationale, these potentially significant advances in aircraft efficiency were stymied by a catch-22: the government was only prepared to provide financial support for the development of an operational prototype if operational performance had already been demonstrated. This case also highlights the challenges faced in the commercial uptake of radical aviation technologies, even when they appear to offer greater efficiency and environmental benefits.

ABSTRACT Direct turbulence measurements using TurboMAP over a “small ridge” on the continental shelf off Jogashima, Sagami Bay, Japan revealed an active layer of topographically induced turbulence. The active layer ( = 10-7 - 10-6 W kg-1) located at mid-depth of 200 – 250 m, occurred on alternate side of “small ridge” depending on the direction of the tidal current. This active layer was accompanied by rebounded-isopycnal surfaces 26.0 - 26.1 σθ , in which all in qualitative manner showed an internal hydraulic flow control on the shelf. The turbulence friction velocity was two order of magnitude lower than observed- in this active layer explaining a less role of bottom friction than hydraulic flow to the high turbulence layer.

Mediating Variables

In the existing literature, studies rarely found in the context of mobile shopping incorporate the concept of flow in their research. This study aims to examine and analyze the role of the concept of flow in which three dimensions of flow are chosen, including flowconcentration, flow-control, and flow-enjoyment as an intervening variable to perceived usefulness and purchase intention through Shopee shopping services. The concept of flow related to studies with the context of mobile shopping is scarce. The type of this study is explanatory research. For this reason, this study had been examined 153 respondents who have used Shopee shopping services. Data were collected using a questionnaire and analyze for in-depth studies of related variables. The results show that the concept of flow from the three dimensions is proven to be an intervening variable between perceived usefulness and repurchase intention. Future exploration additionally can be applied to the business division with a bigger scope and more extensive topographical region.
