This paper presents a rigorous evaluation of a novel, distributed chemical plume tracing algorithm. The algorithm is a combination of the best aspects of the two most popular predecessors for this task. Furthermore, it is based on solid, formal principles from the field of fluid mechanics. The algorithm is applied by a network of mobile sensing agents (e.g., robots or micro-air vehicles) that s...
Background: Quantitative fluorescence-polymerase chain reaction (QF-PCR) is an inexpensive and accurate method for the prenatal diagnosis of aneuploidies that applies short tandem repeats (STRs) as a chromosome-specific marker. Despite its apparent advantages, QF-PCR is not applicable in all cases due to the presence of uninformative STRs. This study was carried out to investigate the efficienc...
The Proportional Responsibility for Integrated Metrics by Encounter (PRIME) model is a novel means of allocating patient experience scores based on the proportion of each physician's involvement in care. Secondary analysis was performed on Hospital Consumer Assessment of Healthcare Providers and Systems surveys from a tertiary care academic institution. The PRIME model was used to calculate spe...
INTRODUCTION Delayed discharge from acute hospital has been a cause of concern for the last 10 years. Older people with complex health needs are particularly vulnerable to delayed discharge with negative consequences for their health and wellbeing. SOURCE OF DATA Review of the literature on the impact of the Community Care (Delayed Discharge) Act (2003) and subsequent policy initiatives on de...
Cellular automata (CA) models have been for several years, employed to describe urban phenomena like growth of human settlements, changes in land use and, more recently, dispersion of air pollutants. We propose to adapt CA to study the dispersion of anthropogenic heat emissions on the micro scale. Three dimensional cubic CA with a constant cell size of 0.15 m have been implemented. Simulations ...
In this paper, simulation of fire in a short 2-lane road tunnel and its evacuation are described. Two traffic situations in the tunnel and their impact on people evacuation in fire conditions are analyzed. For simulation of the tunnel fire, the FDS (Fire Dynamics Simulator) system, version 5.5.3 based on advanced CFD (Computational Fluid Dynamics) fire model is used. The evacuation of people in...
I present four-frequency radio observations of the wide-angle tail radio galaxy 3C 130. By a technique of simulated observations, I assess the systematic errors in the data due to the varying uv plane coverage in the different observations used. Using spectral tomography I show that, at least in the southern plume, the source can be represented by a two-component model consisting of a flat-spec...
In the event that a bacteriological or chemical toxin is introduced to a water distribution network, a large population of consumers may become exposed to the contaminant. A contamination event may be poorly predictable dynamic process due to the interactions of consumers and utility managers during an event. Consumers that become aware of a threat may select protective actions that change thei...
As an alternative to often costly computational fluid dynamics (CFD) modelling of a data center (DC), we describe an ultra-low cost solution based on a wired sensor network. We describe the sensor hardware, packaging and cabling in detail, as well as the software components. Our prototype has been in production use for twelve months at the time of writing. This article presents detected air flo...
This chapter presents an operational grammar for German spatial language, in particular German locative phrases, as a case study for processing distributed information. It investigates the complex interplay of syntactic phenomena and spatial semantics, with a specific emphasis on efficient processing of syntactic indeterminacy and semantic ambiguity. Since FCG applies constructions in a sequenc...
