Fig. 1. Traditional network model and fabric model Abstract—This chapter describes an architecture for slicing, virtualizing, and federating wireless sensor network (WSN) resources. The architecture, which we call KanseiGenie, allows users—be they sensing/networking researchers or application developers—to specify and acquire node and network resources as(More)
This paper deals with challenges in federating wireless sensing fabrics. Federations of this sort are currently being developed in next generation global end-to-end experimentation infrastructures, such as GENI, to support rapid prototyping and hi-fidelity validation of protocols and applications. On one hand, federation should support access to diverse(More)
As a first step towards predictable, repeatable WSN experimentation, we propose the resource specification language LENS (a.k.a. Language for Embedded Networked Sensing) for WSN experimentation infrastructures. Using the Resource Description Framework (RDF) and the Web Ontology Language (OWL), LENS defines a semantic ontology for WSN resources; LENS enables(More)
Metrics that aggregate the state of neighboring nodes are frequently used in wireless sensor networks. In this paper, we present two primitives that exploit simultaneous communications in 802.15.4 radios to enable a polling node to calculate with low power the number (or set) of its neighbors where some state predicate of interest holds. In both primitives,(More)
BACKGROUND Developed countries use generic competition to contain pharmaceutical expenditure. China, as a developing and transitional country, has not yet deemed an increase in the use of generic products as important; otherwise, much effort has been made to decrease the drug prices. This paper aims to explore dynamically the price and use comparison of(More)
—This paper is an attempt to provide a language front-end to synthesise asynchronous control circuits using NCL technology. The target implementation being delay insensitive (DI), the specification language should be DI as well. Delay Insensitive Sequential Processes (DISP) is a process algebra where the behaviour of asynchronous control logic blocks is(More)
—The energy efficiency of the widely used converge-cast pattern depends substantially on the choice of medium access control (MAC) and routing protocol. In this paper, we formalize the maximization of convergecast energy efficiency with respect to its MAC and routing as a resource constrained optimization problem. We then analytically show that this(More)
During Bacillus subtilis sporulation, segregating sister chromosomes are anchored to cell poles and the chromosome is remodeled into an elongated structure called the axial filament. Data indicate that a developmentally regulated protein called RacA is involved in these functions. To gain insight into how RacA performs these diverse processes we performed a(More)
BACKGROUND Pharmaceutical expenditure is currently rising by 16% per annum in China, greater in recent years. Initiatives to moderate growth include drug pricing regulations, essential medicine lists and encouraging generic prescribing. These are principally concentrated in hospitals, which currently account for over 80% of total pharmaceutical expenditure.(More)
