Using the roadeng system to design an optimum forest road variant aimed at the minimization of negative impacts on the natural environment [PDF]

open access: yesJournal of Forest Science, 2002
The optimization study was carried out in the part of the Jeseníky Mts. region in order to find the optimum variant of a forest road route. The ROADENG system was used for determining the Jezerná forest road design with use of projection above the ...

ENVIRONMENTAL ASPECTS IN SELECTING OPTIMUM VARIANT OF SEWAGE SLUDGE MANAGEMENT

open access: yesEnvironmental Engineering and Management Journal, 2022
Sewage sludge management is a current problem worldwide because of its increasing quantities and the presence of contaminants. Its sustainable handling should be socially acceptable, cost- effective method that meets requirements of the efficient recycling of resources and ensures that harmful substances are not transferred to humans or the environment.

Simultaneous Improvement of Final Product-Tolerance and Thermostability of GH39 Xylosidase for Prebiotic Production by Directed Evolution

open access: yesFoods, 2022
Xylosidases are widely used for the production of prebiotics and the transformation of natural active substances in the food industry. However, xylosidases with excellent thermostability and product tolerance are required for industrial applications.

Reduced-state variant of optimum MAP equaliser

open access: yesElectronics Letters, 1999
Although the reduced-state technique has been widely used in Viterbi equalisers, its application to maximum a posteriori probability (MAP) equalisers is not satisfactory because it cannot operate due to the backward recursion of the conventional MAP algorithm.

Optimum designs for next-generation sequencing to discover rare variants for common complex disease [PDF]

open access: yesGenetic Epidemiology, 2011
Recent advances in next-generation sequencing technologies make it affordable to search for rare and functional variants for common complex diseases systematically. We investigated strategies for enriching rare variants in the samples selected for sequencing so as to optimize the power for their discovery.

The NLMS Algorithm with Time-Variant Optimum Stepsize Derived from a Bayesian Network Perspective [PDF]

open access: yesIEEE Signal Processing Letters, 2015
In this article, we derive a new stepsize adaptation for the normalized least mean square algorithm (NLMS) by describing the task of linear acoustic echo cancellation from a Bayesian network perspective. Similar to the well-known Kalman filter equations, we model the acoustic wave propagation from the loudspeaker to the microphone by a latent state ...
