Thereby, when documenting disease freedom, the number of samples per species can be adjusted so that the most cost-efficient samples are collected.
When a ground and vegetation cover factor related to soil erosion is mapped with the aid of remotely sensed data, a cost-efficient sample design to collect ground data and to obtain an accurate map is required.
Doing so by implementing effective, and cost-efficient sampling protocols will help to optimise time and financial resources, particularly relevant to a disease such as schistosomiasis currently reliant on a single available drug.
We formulate a new problem for efficient monitoring of the collective attention dynamics, and we propose a cost-efficient sampling strategy that takes the users' hashtag adoption frequency, connectedness and diversity into account, with a stochastic sampling algorithm to cope with the variability of the sampling targets.
In the optimization process variance functions and cost functions have to be linked in order to derive the optimal (i.e. most cost-efficient) sampling alternative.
Because eggs and hatchlings are proxies of past and present adult pathogen exposure (3, 4 ), the difficult and sometimes disruptive sampling of adults can be circumvented by the rapid and cost-efficient sampling of their young, which will facilitate monitoring efforts.
Optimisation of the laser microdissection technique was crucial for efficient and cost effective sample collection.
Under these assumptions regression estimates that require full coverage are now more cost efficient than 2-phase sampling with regression estimators.
The most cost efficient method is to send samples in maximal 2 kg dry ice.
The aim of this study was to find a preservation method that is reliable and allows cost efficient long time transport of the samples.
Starting with a lube sampler is the most cost efficient and fun way to explore a variety of lubes and figure out what lube feels best.
