The concept of a construction solution of a robot for harvesting strawberries [PDF]

open access: yesE3S Web of Conferences, 2019
Strawberry fruit products are of high commercial and consumption value, while difficult to harvest due to their very low mechanical strength and difficulties in identifying them within the plants.

The Role of Natural Laccase Redox Mediators in Simultaneous Dye Decolorization and Power Production in Microbial Fuel Cells [PDF]

open access: yes, 2018
Redox mediators could be used to improve the efficiency of microbial fuel cells (MFCs) by enhancing electron transfer rates and decreasing charge transfer resistance at electrodes. However, many artificial redox mediators are expensive and/or toxic.

Simplifying products of fractional powers of powers [PDF]

open access: yesACM Communications in Computer Algebra, 2013
Most computer algebra systems incorrectly simplify z -- z /√ w 2 1/ w 3 -- w √ w 2 to 0 rather than to 0/0. The reasons for this are:

Thermoelectric heat exchange and growth regulation in a continuous yeast culture

open access: yesMicrobiologyOpen, 2019
We have designed a thermoelectric heat exchanger (TEHE) for microbial fermentations that is able to produce electric power from a microbial continuous culture using the intrinsic heat generated by microbial growth.

Powers of a product of commutators as products of squares [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We prove that for any odd integer N and any integer n > 0, the Nth power of a product of n commutators in a nonabelian free group of countable infinite rank can be expressed as a product of squares of 2n + 1 elements and, for all such odd N and integers n, there are commutators for which the number 2n + 1 of squares is the minimum number such that

Integration of wind power production in a conventional power production system: stochastic models and performance measures

open access: yes, 2013
A stochastic programming model for the daily coordination of hydro power plants and wind power plants with pumped storage is introduced, with hourly wind power production uncertainty represented by means of a scenario tree.

Comparative Evaluation of Coated and Non-Coated Carbon Electrodes in a Microbial Fuel Cell for Treatment of Municipal Sludge

open access: yesEnergies, 2019
This study aims to provide insight into the cost-effective catalyst on power generation in a microbial fuel cell (MFC) for treatment of municipal sludge. Power production from MFCs with carbon, Fe2O3, and Pt electrodes were compared.
