Errors in the administration of intravenous medications in hospital and the role of correct procedures and nurse experience
(BMJ Publishing Group Ltd and the Health Foundation, 26 M)Background Intravenous medication administrations have a high incidence of error but there is limited evidence of associated factors or error severity.Objective To measure the frequency, type and severity of intravenous ... 
Three Open Problems on the Wijsman Topology
(arXiv, 2016)Since it first emerged in Wijsman's seminal work [29], the Wijsman topology has been intensively studied in the past 50 years. In particular, topological properties of Wijsman hyperspaces, relationships between the Wijsman ... 
Oscillation Revisited
(arXiv, 2016)In previous work by Beer and Levi [8, 9], the authors studied the oscillation Ω(f, A) of a function f between metric spaces hX, di and hY, ρi at a nonempty subset A of X, defined so that when A = {x}, we get Ω(f, {x}) ... 
A novel network selection mechanism for vehicletoinfrastructure communication
(IEEE, 2016)The commercial deployment of 5G networks require heterogeneous multitier, multiple radio access technologies (RATs) to support vehicletoinfrastructure (V2I) communication with diversified services. Vehicles may need to ... 
A foundation programme preparing students for future study in Computing and Engineering Degrees
(IEEE, 2016)This paper presents the Certificate of Science and Technology (CertScT) a predegree programme at Auckland University of Technology in New Zealand, developed with the aim of preparing students to undertake degree level ... 
Pricing Variance Swaps in a Hybrid Model of Stochastic Volatility and Interest Rate With Regimeswitching
(arXiv, 2016)In this paper, we consider the problem of pricing discretelysampled variance swaps based on a hybrid model of stochastic volatility and stochastic interest rate with regimeswitching. Our modeling framework extends the ... 
Accurate calculations of Stationary Distributions and Mean First Passage Times in Markov Renewal Processes and Markov Chains
(De Gruyter Open, 2016)This article describes an accurate procedure for computing the mean first passage times of a finite irreducible Markov chain and a Markov renewal process. The method is a refinement to the Kohlas, Zeit fur Oper Res, ... 
Why the Kemeny Time is a constant
(De Gruyter Open, 2016)We present a new fundamental intuition for why the Kemeny feature of a Markov chain is a constant. This new perspective has interesting further implications. 
Analysing university students' abilities in making assumptions in a ballistics model: a case study
(The Bronx Colleges of the City University of New York, 2016)This paper investigates abilities of two groups of university students in making assumptions in a ballistics model. The first group consisted of postgraduate students majoring in applied mathematics from a New Zealand ... 
Multiple preemptive EDCA for emergency medium access control in distributed WLANs
(Springer, 2016)The increasingly use of wireless local area networks (WLANs) in public safety and emergency network services demands for a strict quality of service (QoS) guarantee especially a large number of users report an emergency ... 
EMAC: an evolutionary solution for collision avoidance in wireless ad hoc networks
(Elsevier, 2016)Transmission collision is a main cause of throughput degradation and nondeterministic latency in wireless networks. Existing collisionavoidance mechanisms for distributed wireless networks are mostly based on the random ... 
The Computation of Key Properties of Markov Chains via Perturbations
(arXiv, Cornell University Library, 2016)Computational procedures for the stationary probability distribution, the group inverse of the Markovian kernel and the mean first passage times of a finite irreducible Markov chain, are developed using perturbations. The ... 
Noninformative reparameterisations for locationscale mixtures
(Cornell University Library, 2016)While mixtures of Gaussian distributions have been studied for more than a century (Pearson, 1894), the construction of a reference Bayesian analysis of those models still remains unsolved, with a general prohibition of ... 
Model prior distribution for variable selection in linear regression models
(Cornell University Library, 2016)In this work we discuss a novel model prior probability for variable selection in linear regression. The idea is to determine the prior mass in an objective sense, by considering the worth of each of the possible regression ... 
Comparisonbased systemlevel fault diagnosis protocols for mobile adhoc networks: a survey
(Elsevier, 2016)Fault diagnosis is crucial for the successful deployment and operation of mobile adhoc networks (MANETs). Comparisonbased fault diagnosis is a practical approach to identify the status of nodes based on tasks they execute. ... 
Error estimates for the Galerkin finite element approximation for a linear second order hyperbolic equation with modal damping
(South African Symposium of Numerical and Applied Mathematics (SANUM), 2016)No abstract. 
Challenges and recommendations for the design and conduct of Global Software Engineering courses: a systematic review
(Association for Computing Machinery (ACM), 2015)Context: Global Software Engineering (GSE) has become the predominant form of software development for global companies and has given rise to a demand for students trained in GSE. In response, universities are developing ... 
Conversing at Many Layers: Implementing Multilayer Onchip Protocol Converters
(2015)The numerous intellectual property blocks of a systemonachip must be integrated so that they can meet systemspecific requirements. However, such integration is not guaranteed due to mismatches between IP protocols. ... 
Finding a closest match between wifi propagation measurements and models
(IEEE, 2015)In a series of papers by Sarkar and his team conducted radio propagation measurements to study the performance of WiFi in terms of received signal strengths (RSS) in an obstructed office block. The goal of this paper is ... 
Gateway load balancing and routing selection scheme of MANET in disaster scenario
(IEEE, 2015)After disaster occurs like earthquake, it is common results of collapse structure. It is impossible for disaster victims make use of communication devices such as cellular phones, iPad or laptop to communicate with others ...
