Random Early Drop (RED) is widely applied in Mobile Ad-hoc NETworks (MANETs) for congestion control. It randomly drops packets to prevent congestion from occurring, while keeping proper queue size of Route Request (RREQ) packets at the same time. Unfortunately, in the case of severe congestion and large amounts of RREQ packets in the queue, RED algorithm with tune parameters is not able to impr...

We investigated the utility of time-lapse photography to provide population estimates and lamb : ewe ratios of mountain sheep populations. We compared 2 methods of time-lapse data analysis: group sampling and frame sampling. We failed to reject the null hypothesis that population estimates and lamb : ewe ratios from time-lapse and direct observation sampling were the same.

I derive analytically the spectrum of the CMB fluctuations. The final result for Cl is presented in terms of elementary functions with an explicit dependence on the basic cosmological parameters. This result is in a rather good agreement with CMBFAST for a wide range of parameters around concordance model. This allows us to understand the physical reasons for dependence of the particular featur...

Aims Data assimilation is a useful tool to extract information from large datasets of the net ecosystem exchange (NEE) of CO2 obtained by eddy-flux measurements. However, the number of parameters in ecosystem models that can be constrained by eddy-flux data is limited by conventional inverse analysis that estimates parameter values based on one-time inversion. This study aimed to improve data a...

A compact graphical device for combining survival and time-varying covariate information is proposed. The proposed graph contains the Kaplan-Meier estimator for right-censored data and a simultaneous display of the behaviour of time-dependent covariate(s) and the lifetime for each subject in the sample. The observed levels of time-dependent covariates are possibly subjected to an initial dimens...

OBJECTIVES To identify factors that influence the extent to which general practitioners use absolute risk (AR) assessment in cardiovascular disease (CVD) risk assessment. DESIGN, SETTING AND PARTICIPANTS Semi-structured interviews with 25 currently practising GPs from eight Divisions of General Practice in New South Wales, Australia, between October 2011 and May 2012. Data were analysed using...
