When a regulator cannot observe or infer individual emissions, corrective policy must rely on ambient pollution data. Assuming this kind of environment, we study a class of differential games of pollution control with profit functions that are polynomial in the global pollution stock. Given an open-loop emissions strategy satisfying mild regularity conditions, an ambient transfer scheme is exhi...

When exploring large spatial datasets, zooming and panning interactions often lead to the loss of contextual overview. Existing overview-plus-detail approaches allow users to view context while inspecting details, but they often suffer from distortion or overplotting. In this paper, we present an off-screen visualization method called Ambient Grids that strikes the balance between overview and ...

Peer-to-peer (P2P) networks are being developed all around us and used for a growing number of applications. At the same time Ambient Intelligence is an upcoming branch on the IT-tree, demanding quick and easy connection of mobile devices into the network and constant access to all data on all devices in that network for all users. Peer-to-peer technology seems the perfect basis for a Ambient I...

Weyl geometry is a natural extension of conformal with covariance mediated by connection. We generalize the Fefferman-Graham (FG) ambient construction for manifolds to corresponding manifolds. first introduce Weyl-ambient metric motivated Weyl-Fefferman-Graham (WFG) gauge. From top-down perspective, we show that space as pseudo-Riemannian induces codimension-2 geometry. Then, from bottom-up sta...

In MANET applications, a common pattern is to maintain and query time-varying collections of remote objects. Traditional approaches require programmers to manually track the connectivity state of these remote objects and adding or removing them from local collections on a per-object basis. Queries over these collections have to be manually recomputed whenever the collection or its elements chan...

It is recognized in Ambient Intelligence that ambient devices should be modeled as intelligent autonomous components rather than passive information sources. The agent paradigm suits well for representation of both intelligent ambient devices and humans. However, modeling complex cognitive dynamics from which intelligent behavior of agents emerges is not trivial. In this paper a formal framewor...

Study on ambient and cryogenic grinding was performed to test the novelty of cryogenic grinding and pin point the drawbacks of ambient grinding. Comparative study had shown that ambient grinding need more power (8.92%) and specific energy (14.5%) than cryogenic grinding. Particle size analysis had shown that cryogenic grinding produced coarser particles. Comparative study of energy law constant...

The effect of olfactory stimuli on consumer behaviour has received little attention in marketing and retailing literature compared to other atmospheric cues. Researchers report ambiguous findings and shortcomings of measurement approaches. Based on a critical literature review, a field experiment in a regional shopping mall investigates the effectiveness of ambient scent. Before-and-after surve...
