The article examines existing methods for assessing the homogeneity of feed mixes in industry and agriculture. As an alternative to approaches, authors offer a low-cost online technology assess feed. feedstuff under study includes cattle or compound consisting naturally-grown (green mass freshly cut grass, haylage, corn silage, etc.) concentrated components (grain milling, sunflower, soybean me...

In this paper, a software-based implementation of a Traffic Detective for radio traffic monitoring in the 868 MHz band is presented. Besides the user-friendly graphical user interface of the Android app, this paper reports about the algorithms used for traffic monitoring and automatic communication standard recognition, implementation aspects as well as the receiver hardware used. Finally, use-...

Leaf area index (LAI) is a key biophysical parameter used to determine foliage cover and crop growth in environmental studies in order to assess crop yield. Frequently, plant canopy analyzers (LAI-2000) and digital cameras for hemispherical photography (DHP) are used for indirect effective plant area index (PAIe f f ) estimates. Nevertheless, these instruments are expensive and have the disadva...

Currently, portable X-ray fluorescence (PXRF) analysis is widely used as an auxiliary method for the preliminary investigation of soil heavy metal contamination. In this study, a smart glasses-based application (app) was developed to support field workers performing contamination surveys with PXRF analyzer. The app using MIT App Inventor and runs on glasses based optical head-mounted display th...

The routine measurement of direction-dependent reservoir rock properties like permeability often takes place along the axial direction of core samples. As permeability is a tensor property of porous materials, it should be fully described by a tensor matrix or by three main permeabilities in principal directions. Due to compaction, cementation, and other lithification processes, which take plac...
